What are the standard requirements for the appearance of silicone products? With the development of science and technology and the improvement of product quality and performance requirements, silicone products have been widely used in all walks of life. As one of the important measurement factors, the appearance quality of silicone products is also getting more and more attention. So, what are the standard requirements for the appearance of silicone products?     1. Uniform color The color of silicone products is one of the important indicators of appearance quality. Qualified silicone products should have uniform color, no obvious color difference or uneven color phenomenon. In the production process, the appearance quality of silicone products has an important impact on its performance and use. This article will introduce some standard requirements for the appearance of silicone products.   2. Smooth surface The surface of silicone products should be smooth and flat, without obvious bumps, cracks, bubbles and other defects. These defects will not only affect the beauty of the product, but also affect the performance and service life of the product. Therefore, in the production process, effective measures should be taken to ensure the surface quality of the product. For example, in the field of food packaging, the surface smoothness of silicone products can affect the taste and preservation effect of food. Therefore, in the production process, it is necessary to ensure that the surface smoothness of silicone products meets the relevant standards.   3. Dimensional accuracy The dimensional accuracy of silicone products is also one of the important indicators of appearance quality. Products with high dimensional accuracy not only have high aesthetics, but also can better meet the production and use requirements. Therefore, in the production process, it should be strictly operated in accordance with the process requirements to ensure the dimensional accuracy of the product.   4. Uniform thickness The thickness of silicone products is also one of the important indicators of appearance quality. For some parts that need precise coordination, such as silicone buttons, seals, etc., more attention should be paid to the control of dimensional accuracy.   5. Good toughness Silicone products have a certain toughness and can withstand a certain amount of bending and distortion. In the production process, effective measures should be taken to ensure that the toughness of the product is good, to avoid cracks, bubbles and other defects. In the production process, the corresponding high temperature or low temperature resistance test should be carried out according to the actual use environment to ensure that the product can maintain good performance in various environments.   6. Aging resistance Silicone products will be affected by the natural environment during use, such as sunlight, oxygen, etc., so they must have certain aging resistance. In the production process, environmentally friendly materials and processes should be used to avoid the use of substances harmful to the human body. At the same time, the product should not produce harmful substances during use to ensure the environmental protection of the product. In the production process, the corresponding aging test should be carried out according to the actual use environment to ensure that the product maintains good performance during its service life.

Aging life is the hard wound of the silicone ring, all suitable for the sealing benefits of silicone products have such a disadvantage, such as our common machine doors and Windows, electrical product sealing and car waterproof sealing ring in the middle of the city found the inevitable shortcomings, regardless of the choice of silicone or rubber and other materials through the situation and the training of time are gradually lost efficacy can not reach the reality Fruit, showing the benefits of not producing things. There are many important reasons that affect the application life, but the silicone ring will be affected by several common signs in the service seal. Affected by the strength of the roughly shrinkable permanence, According to the different method of placement, plane, rugged groove or groove, etc., the difference in the placement method of each product is very likely to cause the uneven force to find the force center shift, and the discovery side is heavy The edge light causes shrinkage permanent deformation through the permanent accumulation force, and when the sealing silicone ring is removed again, it is very likely that the shape situation has been found, so the average and the level of the force need to be mastered at the same time. The product size is wrong resulting in fracture deformation The gap question can be divided into several components, first, because of the material of the rubber material question, very many silica gel material because of the formula found poor resilience, tensile force is not enough to cause the problem in the application process is not strong enough to find cracks caused by leakage, Silica gel ring and manufacturers processing questions: for example, the product is brittle resulting in the relatively thin thickness of the silica gel product, it is easy to find this question, and the product is soft causing the rubber material to have an internal bulge, and the deformation of the cracks is found after stretching and compression forever. The product is soft or brittle resulting in ineffective effect, very often not the layout of the material and the product, but in the middle of the silicone rubber product manufacturer manufacturing process caused by the product character specifications are affected, such as the hardness and softness of the final product when processing, the processing time is extended resulting in the product is too brittle in the process of installation found cracking signs, and probably want to be promoted The product is found to be soft, resulting in deformation signs when the product is stressed. Hard and soft influence, very often based on the difference in the softness of silicone rubber products can completely change the efficacy and layout of the product, so the silicone sealing ring in the application process because of the selection of different hard and soft in the force, Tensile, extrusion and other signs are found, the sealing ring will find a few unavoidable questions, such as extrusion cracks, excessive strength, high hardness, product deformation without rebound and so on.

Silicone products punching processing should pay attention to what, silicone products are a very common product type, there is a large part of the world people will use silicone products. Silicone products are produced by professional silicone products manufacturers, and silicone products manufacturers will turn raw materials into silicone products through a series of processes. In the production of silicone products, there is a processing is punching.   Metal die processing is currently a more common process, is widely used in a number of industries, for the current electronic chip integrated materials and precision metal sheet it is indispensable, and in addition to these, for the rubber and plastic industry die-cutting process can also be widely used, In the production process, there are great advantages in terms of product quality and efficiency. At present, many silicone rubber plugs and silicone foot pads and ultra-thin sheet products will choose the punching process, its main advantage is to take a certain degree of precision and processing efficiency, mainly used in solid die molding process, usually the use of punching process products need to pay attention to efficiency, and efficiency is continuous punching through the stamping press. The main processing method of the product is to cut the silicone plug from the raw edge of the main body through a sharp blade. In the early stage, it is necessary to pay attention to the processing method of the mold. Generally, the self-cutting edge of the silicone product mold is increased, but the punching position is reserved. If the mold is not processed in accordance with the punching method in the early stage, then the orderly slicing effect will not be achieved. Silicone products die cutting processing precautions: 1. Put the whole piece of the silicone product into the punching mold. The upper and lower dies of the mold are divided into automatic and manual punching. Usually, the higher precision and the higher pressure punching machine will have better product quality. 2, in the punching process according to the structure of the product to determine its quality, if it is only a flat gasket class, then the punching accuracy is basically not affected, but if there is a circular arc or reverse occlusion part, then the placement is not standard is easy to cause punching offset phenomenon. 3, the quality of the punching die is very important, usually the punching die mainly relies on the sharp edge of the surface, if the knife edge is damaged by the collision, then the product cut out will naturally be affected, and the material is different will also have an impact on the life of the punching die, usually can use copper die, aluminum die and steel die, if the number of processing is large, it is recommended to use large punching machine processing is better. 4, the position of the die machine is very important, usually need to carry out a long time correction adjustment during the sample, if only a single punching is relatively thin silicone rubber products, then the impact will not be very large, if you need two punching more than two times, then you need to pay attention to the pressure of the mold and the precision of the fixture fixed.

Silicone products how to improve the hardness, silicone products because of its excellent elasticity, water resistance and aging resistance, has been widely used in many fields. However, with the continuous expansion of the use of scenarios, the hardness requirements of silicone products are becoming higher and higher. Silicone products manufacturers have a process to improve the hardness of silicone products, so how to improve the hardness of silicone products.   First, the influencing factors of the hardness of silicone products The hardness of silica gel products is affected by many factors, including the choice of silica gel raw materials, the type and amount of vulcanization agent, and the control of vulcanization process. Therefore, to improve the hardness of silicone products, we first need to start with these factors and conduct in-depth research and analysis. Second, the method of improving the hardness of silicone products 1. Choose the right silicone raw materials The properties of silica gel raw materials have a direct impact on the hardness of products. In general, the hardness of products made of silica gel raw materials with higher hardness will also increase accordingly. Therefore, when purchasing silica gel raw materials, the varieties with higher hardness should be selected according to actual needs. 2. Adjust the type and dosage of vulcanizing agent Vulcanizing agent is one of the important factors affecting the hardness of silica gel products. Different types of vulcanizing agents have different effects on the vulcanization rate and hardness development of silica gel. By adjusting the type and dosage of vulcanizing agent, the hardness of silicone products can be effectively improved. It should be noted that the amount of curing agent is not the more the better, excessive use may cause the product hardness is too high and lose elasticity. 3. Optimize the vulcanization process Vulcanization process is the key link in the production of silica gel products. Reasonable vulcanization temperature, time and pressure and other parameters are helpful to achieve the uniformity and stability of the hardness of silicone products. Therefore, in the production process, the vulcanization process should be continuously optimized to improve the hardness of the product. 4. Add hardness enhancer Adding hardness enhancers, such as calcium carbonate, silica black and other inorganic fillers, can effectively improve the hardness of silica gel products. These fillers play a skeleton role in the silicone matrix and increase the rigidity of the product. However, it should be noted that the amount of filler added should be moderate, too much may lead to a decline in product performance. 5. Improve product structure design The structural design of the product also affects its hardness. By optimizing the structure of the product, such as increasing the wall thickness, changing the cross-section shape, etc., the hardness of the silicone product can be improved to a certain extent. In addition, reinforcing bars or other reinforcing structures can be added to the key parts of the product to improve the overall hardness of the product.

How many degrees of high temperature resistance silicone products, silicone products because of its unique physical and chemical properties, in many fields have been widely used. Among them, high temperature resistance is one of the important characteristics of silicone products, which directly determines its use effect in high temperature environment. So, how many degrees can silicone products withstand high temperature?   First of all, we need to understand the basic properties of silicone. Silica gel is a highly active adsorption material, belongs to the amorphous substance, insoluble in water and any solvent, non-toxic and tasteless, chemical stability. This stability allows the silica gel to maintain its original structure and properties at high temperatures.   However, the high temperature resistance of silicone products is not unchanged, it is affected by a variety of factors. The type of silica gel, the production process, the use of additives and other factors will affect the high temperature resistance of silica gel products. In general, ordinary silicone products can withstand higher temperatures, usually around 200 ° C. However, some special processes made of silicone products, its high temperature resistance may be higher, and even can reach more than 300 ° C.   In addition, we also need to note that although silicone products have high temperature resistance, some problems still need to be paid attention to in practical applications. First of all, the long-term high temperature effect may lead to the aging and performance decline of silicone products, so it is necessary to avoid long-term exposure to high temperature environments during use. Secondly, the high temperature resistance of different kinds of silicone products will also be different, so it is necessary to understand the specific high temperature resistance range before use.   In general, the high temperature resistance of silicone products depends on a variety of factors, in general, ordinary silicone products can withstand high temperatures of about 200 ° C, and silicone products made of special processes may have higher high temperature resistance. However, it is still necessary to pay attention to avoid long-term high temperature action during use, and rational use according to the high temperature resistance range of the specific product.

What are the surface treatment processes of silicone products? Silicone products are a very popular product, silicone products have excellent performance and are applied in many fields. Many silicone products have a delicate appearance, which also benefits from the surface treatment process of silicone products.   1, pad printing process: Silicone products printing process is a relatively early surface treatment process, it is suitable for silicone, rubber and plastic hardware and other materials of the printing process, mainly using printing ink through the plastic head mechanical printing, in the early stage mainly using the screen plate for artificial wall chart, and has been basically eliminated, currently with the upgrade of machine equipment, Mechanical printing has developed to multi-color printing and printing multiple colors at the same time through the glue head. The printing effect belongs to the plane, the surface has about 0.05MM printing steps, and the hand will feel a slight step bump effect.   2, molding: Silicone jewelry surface molding is easy, usually can also be directly made on the surface of the product, the product mold surface through the silicone products manufacturers processing concave and convex groove, directly put the silicone material into the mold pressing and curing molding products have concave and convex effect, usually many decorations are made into grooves, can be secondary filling oil processing, Add other colors of silicone ink to the grooves to make the surface of the product an additional pigment. In addition to this way, it can also be molded twice to inject other colors into the surface, this way is not difficult, mainly because the other color K pieces must be put into the mold cavity in the filling processing, the resulting product will naturally be combined with color K to achieve multi-color effect, the difficulty lies in the process of dispensing glue and production efficiency.   3, silicone drop glue, drop glue is currently the most popular process in silicone decorative supplies, mainly through the mold injection into the face of the mold cavity, through the color allocation of color glue can be made at the same time more than a dozen colors, and the effect of the production of glue products will have a certain three-dimensional effect, touch the product can be in the middle of the mold line there will be a color separation slot, the size of about 0.5mm, The product effect made by this process has been recognized by many consumers, and it is also widely used in silicone decorative bracelets and watchbands.   4, transfer: transfer process is divided into many types, in the general film industry there are basically transfer process, such as hardware, ceramics, plastics and other industries, and silicone transfer there are mainly several ways. Heat transfer printing is a more common processing of silicone bracelet, it is mainly printed pattern through high temperature PET polyester film that is printed into a heat transfer flower film, the heat transfer flower film installed on the heat transfer hot stamping machine for printing, simple operation, pattern molding, no need to color. And when some products can not use heat transfer, it is necessary to use the water transfer process, water transfer with special chemical treatment of the film, after printing the required color lines, flat to the surface of the water, the use of water pressure, the color pattern evenly transferred to the surface of the silicone product, when the coating is automatically dissolved in water, after cleaning and drying, and then a layer of transparent protective coating, By this time the product has presented a completely different visual effect. In addition to the above two transfer processes, silicone products are currently more common is the in-mold transfer effect, this way is the same as thermal transfer, the product pattern effect directly into the PET film production, through the mold design structure of the product for alignment molding, and the main technical control of this process is the open mold structure and the film plate alignment screen position. If the screen version is not strictly aligned, the resulting product will cause the overall offset.

With the development of industrial production and scientific skills, we continue to make new requests for conductive silica gel data. In the field of electronic and electrical appliances, because of the rapid development of integration skills and assembly skills, electronic components, logic circuits to light, thin, small direction, heat is also added, and then the need for high thermal insulation data, useful to remove the heat generated by electronic equipment, which is related to the service life of the product and the reliability of quality. The traditional way to deal with the heat dissipation of electronic equipment is to pad a layer of insulating medium between the heating body and the heat dissipation body as thermal conductivity data, such as mica, polytetrafluoroethylene and beryllium oxide ceramics, etc., this method has a certain effect, but there are poor thermal conductivity, low mechanical function, and advanced defects. At present, some of the heat dissipation of electronic equipment is processed by various forms of heat sinks, but most of them are necessary to be processed by thermal conductivity data, and thermal silica gel data is the most important member of thermal conductivity data. In this paper, the application of thermal paste and thermal silicone sheet to provide heat conduction treatment for electronic equipment is proposed. Thermal conductive silicone rubber material is a typical polymer composite material, its thermal conductivity function is mainly determined by the type of thermal conductive filler and the dispersion of thermal conductive filler in the silicone rubber matrix, thermal conductive filler is divided into metal filler and inorganic non-metallic filler, the thermal conductivity mechanism of various fillers is not the same, and the resolution of the difference between thermal conductivity or thermal conductivity. Thermal conductive paste is a mechanical mixture of silicone oil and thermal conductive filler. It has the characteristics of setting at any time, high thermal conductivity, non-curing and no corrosion to interface data. In electronic equipment, there are many contact surfaces and installation surfaces between various electronic components, there is a gap between them, resulting in poor warm flow, in order to deal with this problem, usually fill the thermal paste between the contact surface, use the activity of the thermal paste to sweep the air between the interface, drop or even eliminate thermal resistance.   Thermal silicone sheet is a sheet of thermal insulating silicone rubber processed by a special production process. It has the characteristics of natural viscosity, high thermal conductivity, high compressibility, high cushioning and so on. It is mainly used in the gap filling data of heating equipment and heat sink and casing, because of its soft material and elastic variable under the effect of low pressure force. It can touch the surface of the equipment even for the rough surface structure, reduce the air thermal impedance, and excellent treatment of thermal conductive silicon paste after high temperature silicone oil seepage, dust accumulation on the surface and other defects.

In life, there are many kinds of glass, and its use is also more extensive, such as tempered glass, quartz glass, optical glass and other glass types that are common in our life, and then we will understand what quality requirements optical glass has?   Glass that can change the direction of light propagation and change the relative spectral distribution of ultraviolet, visible or infrared light. The narrow sense of optical glass refers to colorless optical glass, and the broad sense of optical glass also includes colored optical glass, laser glass, quartz optical glass, anti-radiation glass, ultraviolet infrared optical glass, fiber optical glass, acousto-optic glass, magneto-optical glass and photochromic glass. Optical glass can be used to manufacture lenses, prisms, mirrors and Windows in optical instruments. Components made of optical glass are key components in optical instruments.   1, the specific optical constant and the consistency of the optical constant of the same batch of glass Each type of optical glass has a specified standard refractive index value for different wavelengths of light, which is used as the basis for optical designers to design optical systems. Therefore, the optical constant of the optical glass produced by the factory must be within a certain allowable deviation range of these values, otherwise the actual image quality will not be consistent with the expected results at the time of design and affect the quality of the optical instrument. At the same time, because the same batch of instruments are often made of the same batch of optical glass, in order to facilitate the unified calibration of the instrument, the allowable deviation of the refractive index of the same batch of glass is more stringent than their deviation from the standard value.   2. High degree of transparency The brightness of the optical system image is proportional to the transparency of the glass. The transparency of optical glass to a certain wavelength of light is expressed by the optical absorption coefficient Kλ. After light passes through a series of prisms and lenses, part of its energy is lost by reflection at the interface of the optical part and the other part is absorbed by the medium (glass) itself. The former increases with the increase of the refractive index of the glass, and this value is very large for high refractive index glass, such as a surface light reflection loss of about 6% for heavy flintlock glass. Therefore, for the optical system containing multiple thin lenses, the main way to improve the transmittance is to reduce the reflection loss of the lens surface, such as coating the surface anti-reflection film. For large-size optical parts such as the objective lens of an astronomical telescope, due to its large thickness, the transmittance of the optical system is mainly determined by the light absorption coefficient of the glass itself. By improving the purity of the glass raw material and preventing any coloring impurities from mixing in the entire process from mixing to melting, it is generally possible to make the light absorption coefficient of the glass less than 0.01(that is, the light transmittance of the glass with a thickness of 1 cm is greater than 99%).
