The hardness of silicone products is one of the important test indicators. In general, the higher the content of rubber, the lower the hardness. The hardness of silicon is based on Shore hardness standard, and the instrument is also measured by Shore hardness tester. The hardness is between 0 and 100 degrees, and its use varies depending on the purpose of the product. Silicon products according to the different process, hardness is also different, the process has liquid-solid method and liquid-solid method.   Liquid silicone processing can be used to make 0-20 degrees of "low grade" silicone rubber products, even if you have this material on hand, it is still very sticky. Such silicone products are usually rare, and developing a set of liquid silicone product molds is particularly expensive. For a small number of people, it usually costs thousands of dollars. Most fluidized bed processes are at 1020 degrees. Some silicone rubber products are produced with liquid technology, and silicone rubber products produced with liquid technology are easy to produce uneven edges due to material reasons. The liquid process is suitable for low order silicone products and does not require very strict automatic assembly. The second is the solid process, at present, the softness of the solid silicone process is at least 30 degrees, and the maximum is about 80 degrees, although it can also reach a higher degree, but the failure rate is too high, the product is very brittle, and it is not easy to disassemble by itself. Therefore, the best hardness of solid state processing is between 30 degrees and 70 degrees. Can not make softer products, but can automatically discharge the edge, the product appearance is beautiful, no burrs. Generally, the hardness of silicone rubber products is between 30-80, which is also the hardness of silicon gel commonly used in most silicone products. Silicone rubber products have good toughness, good elasticity, because the external force is not easy to deform, there will be a layer of oily substances, so the touch is very smooth.

Many silicone gaskets are glued by pasting double-sided tape to prevent slipping after too long, so in normal use, in addition to human conditions, 3M gaskets will not easily fall off, because in the glue process and processing also need certain skills, and these experience skills will enhance the tightness of silicone gaskets. What are the specific gasket gluing methods? The premise of making high-quality gaskets must be to do the corresponding preparation work, such as the main product of the silicone gasket are to achieve the glue effect, which naturally can not get a good effect, so the face of the silicone gasket is required to be clean without impurities, dry without oil and liquid, the surface of the gasket should be clean and smooth, and there should be no potholes.   Silicone gaskets usually have two forms of backgluing, manual and fixture, manual backgluing is mainly for proofing and small batch trial production processing, in the case of no fixture die memory manual cutting, such as a class with higher corner requirements is not recommended, fixture die for mass production and processing, The premise of this method is that the silicone gasket processing manufacturer needs to do a good job in advance of the mold opening mode has been self-dismantling, and the edge is removed by punching after pasting the back glue, which is of high precision and fast efficiency. The pressure problem is secondary, the usual degumming phenomenon is likely to be caused by the size of the pressure, usually to achieve a good adhesive effect, the need to apply pressure to 3M glue and the bonding surface, so that the adhesive paper and the gasket have sufficient contact bonding, usually manual pressure is not as good as the scraper, and the scraper is not as good as the pulley, the pulley is different liquid machine, different silicone gasket requirements choose different pressure instruments.   Silicone gasket backing process is not complex, usually several reasons lead to the problem of backing glue, in addition to the silicone gasket manufacturers of raw materials and 3M rubber paper material accidents are basically controllable range, so choose a high-quality gasket supplier and material is important!

Food grade silicone rubber or nylon and stainless steel skeleton on the typical surface, the silicone rubber can be used at 200° C only slightly high temperature aging long-term tolerance, and aging in the air atmosphere is mainly carbon dioxide, water, silicon dioxide amount is small, no danger. So, from a security point of view, it doesn't feel like there's a big problem. But cooking at a low temperature, or using a pot at a higher temperature can extend the life of the bottom without long-term contact. Originally kitchenware silicone rubber was first designed by the West, the main case is that it is cooked at low temperatures. Or large frying oil scenes are actually more appropriate wooden or stainless steel cookware.   Silicone kitchenware is silicone products using a food grade FDA,LFGB as the standard of special silicone as raw materials, with its own unique environmental protection, chemical and technical performance is relatively stable, high temperature resistance, soft, anti-fouling, dirty, non-stick and other superior performance, in many research materials kitchenware stand out. The chemical structure of silica gel raw materials is very stable, and the products made have a longer life than other related materials. And more soft and comfortable: thanks to the softness of silicone nanomaterials, silicone kitchenware feels comfortable, has the development of flexibility, not easy to deformation. Many colors: According to the needs of corporate customers, deploy a variety of different colors. Environmental protection, safety and non-toxic: from raw materials into the factory to finished products are impossible to produce no treatment of toxic and harmful social substances. So the use of silicone spatula for stir-frying is no problem, you can rest assured that we use!  

Glass panels are an integral part of modern homes, and their cleaning and maintenance are critical. The correct cleaning and maintenance methods can extend the service life of the glass panel, so that it is always beautiful and clean, and create a comfortable and pleasant environment for the family. Let's take a look at how to clean and maintain glass panels.   First of all, cleaning the glass panel needs to choose the right detergent. In general, ordinary water and neutral cleaning agents can easily clean the glass panel. When using cleaners, you need to be careful not to use too much, so as not to residue, causing white residue on the glass panel. If it is a strong acidic or alkaline cleaner, it must be avoided, so it is easy to damage the glass panel.   Secondly, cleaning the glass panel also needs to choose the right tool. Generally speaking, we can use a soft cloth or sponge to clean the glass panel. Special attention should be paid to the use of hard tools, such as brushes or steel balls, so that it is easy to scratch the glass panel.   In addition, glass panel cleaning needs to pay attention to the frequency of cleaning. If you usually do not pay attention to cleaning, the accumulated dirt will be more and more difficult to clean, you need to use greater strength and stronger cleaners, at this time, the glass panel is easy to be scratched or deformed. It is recommended to perform a simple cleaning and wiping at least once a week to keep the glass panel clean and tidy.   Finally, the maintenance of the glass panel in addition to regular cleaning, but also need to pay attention to prevent collision and friction. It is necessary to avoid heavy objects or sharp objects hitting the glass panel, which is easy to cause cracks or scratches. At the same time, when moving the glass panel, attention should also be paid to avoid friction to avoid scratches on the surface of the glass panel.   In short, the correct cleaning and maintenance methods can extend the service life of the glass panel and protect its beauty and cleanliness. We should choose the appropriate cleaners and tools according to the needs, clean them regularly, and pay attention to prevent collision and friction, so that the glass panel can always remain bright as new.

Anti-slip silicone cushion is widely used in household goods, with the continuous innovation and improvement of daily necessities, more and more silicone floor mat protective gaskets are used in many furniture products, such as boxes, electrical furniture and other fields, many materials choose rubber EPDM or plastic ABS and other materials on the material. The silicone material is also gradually widely used with the concept of environmental protection, so what are the standard requirements for it to achieve non-slip buffering?   The mold surface structure is a more important link, in the installation standard above different silicone products have different effects on anti-slip, such as smooth and fog surface, such as smooth products in the adhesion smooth surface is more viscous, such as the surface of the fog surface anti-slip effect will be reduced, at the same time there are a lot of sungrain concave and convex spot surface, Different sides used in different scenes will have different anti-slip effects. Thickness affects the cushioning of the product, if the silicone rubber mat is too thin in the case of force is likely to be based on the size of the strength of the long-term buffer leading to a decline in life, and the silicone sheet can be done at least 0.3MM, the conventional force is not high, so in the process of cushioning the silicone sheet as thick as possible the better.   Hardness and softness determine the cushioning standard of the product, the softer the hardness of the silicone products may be the better the cushioning resilience of the product, the harder the hardness of the product the better the life of the product, usually the hardness of the product is too high the resilience is relatively low or even no resilience, so you still have to see your silicone gasket for life environment! Speaking of the environment, the use of the product environment is also very important, although the silicone material has more advantages, but in the whole product silicone also has the disadvantage of the use of the environment, such as oil pollution ozone and ultraviolet strong environment anti-aging performance is not better than rubber. At the same time, the silicone rubber washer also has some attention to the standard Angle of installation and use, so as far as possible to achieve a more perfect assembly degree of the product to prevent the reduction of service life!

In our opinion, usually transparent products are generally made of glass, we never thought that one day glass will be eliminated by acrylic products, acrylic products may be based on the disadvantage of glass and constantly improve to replace the glass, then acrylic products jumped on what?   1, acrylic light transmittance is very good, light transmittance of more than 92%, and ordinary glass light transmittance of 85%, so dyed acrylic craft products, in the sunlight, crystal clear, very beautiful!   2, acrylic has a very excellent insulation effect, in many electronic products should be to, such as tablet computers, mobile phones, computers, audio, television and other products used in some very small component insulators, everyone if the electronic products in the maintenance, pay attention to, can see.   3, acrylic weather resistance is very strong, it will not be due to exposure and freezing and other reasons yellow and broken, so that you clean up is also very convenient.   4, acrylic is very environmentally friendly, can be used repeatedly. Everyone may usually encounter, glass cup ah, what broke, is to sweep a broom to the trash bin, some ordinary glass products, when moving, because of heavy, with and inconvenient, lost and pity, and take to sell waste can not sell a good price. But if there are acrylic products at home, don't be such a loser, this material waste recycling, but the price is very high! Everyone knows who the junk collectors are.   5, the shaping freedom of acrylic is very high, can be processed at will to become the type you want very much: Because acrylic material is lighter than ordinary glass material, cutting processing technology is not complex, so acrylic products can basically meet the needs of all walks of life to customize products, such as cosmetics display shelves, photo frames, watch stands, or large to aircraft Windows, combat window covers, tank viewing Angle Windows, size, shape, height and thickness, Can be made according to customer needs   6, acrylic than ordinary glass resistance is more than 20 times higher, this is a foreign country has really done the test, when a certain thickness of acrylic material in front of the test protective body, the standard American M16 assault rifle, continuous shooting, in front of acrylic material always unable to break down, hit the target, so this is why in some foreign heads of special car, The reason why acrylic is widely used as bulletproof material.   7, the corrosion resistance of acrylic is very strong: this can be no exaggeration to tell you that you put strong sulfuric acid directly on the acrylic material, there is no problem.   Based on the above 7 advantages are enough to replace the glass, which is also the reason why acrylic products jumped on, of course, this is only a part of the advantage of acrylic products, otherwise acrylic products will not be applied to various fields.

Silica gel is a kind of polymer material widely used in medical, food, industry and other fields. To achieve medical grade, silicone products need to meet the requirements of the following aspects.   First of all, silicone products are required to use a sterile environment in the production process. Medical silicone products need to ensure that their use will not cause damage to the body, so the production process needs to exclude bacteria and other sources of pollution to prevent possible cross infection.   Secondly, silicone products need to pass strict quality testing. Medical silicone products need to have high purity, high elasticity, high transparency and other characteristics, need to pass various kinds of testing and certification, such as ISO9001 quality management system certification, FDA certification, European CE certification, etc., to ensure that it meets medical standards.   Finally, silicone products need to meet strict biocompatibility requirements. Medical silicone products need to be in contact with human tissues, physiological fluids, etc., so it is necessary to assess the impact of biological buffering, immunity, damage, etc., to ensure that silicone products will not have a negative impact on the human body.   Medical silicone products need to meet certain standards in manufacturing, quality testing and biocompatibility to ensure their safe and effective application in the medical field and escort people's health.

In many industries, rubber components play a vital safety role in everyday activities. For this, rubber components need to be durable. Although in many cases, rubber components have many ways to fail during use, mechanical fatigue is probably the most common failure mechanism, affecting almost all rubber-related components. In the future, we will also explore solutions for other failure mechanisms, such as wear and chips, chemical erosion, expansion and inelastic failures.   When it comes to mechanical fatigue, we are concerned with the long-term performance and service life of rubber components subjected to repeated mechanical loading and unloading cycles. Conveyors, synchronous conveyor belts, different tire components, AV bases require repeated mechanical cycles when working.   The challenge often faced by composite developers is how to extend the fatigue life of components without affecting other performance, or how to improve dynamic performance without affecting the service life of components. Fortunately, in the face of such challenges, we have a rich and well-developed scientific framework to address them, as well as some basic material selection guidelines that can help us.   Deformation control mode   First, we need to understand the loop running conditions of the component. Is rubber deformation controlled by the cyclic load or displacement applied? This is crucial because it helps us adjust the stiffness of the complex to ensure that the storage capacity is minimized in the event of deflection where cracks may occur. For example, under deflection control, we can select a soft compound that minimizes the energy stored in the compound under deflection and inhibits crack propagation. Instead, for load control situations, we can harden the complex to minimize component deflection.   Choice of rubber   The selection of suitable rubber is the most important for mechanical fatigue properties. Natural rubber is an excellent choice for crack and tear resistant compounds. Its ability to crystallize under strain results in automatic strengthening of the crack tip. This mechanism prevents and passivates cracks during cyclic relaxation and non-relaxation deformation. Of course, natural rubber is not suitable for all applications. High temperature operations or chemically harsh conditions require the use of specific synthetic rubber. Compared with natural rubber, the strain crystallization properties of most synthetic rubber are not outstanding. In contrast, synthetic rubber relies entirely on particle strengthening operations to achieve the desired crack growth and tear resistance   Selection of reinforcing agent   Reinforcing agents, such as carbon black, play a crucial role in determining the crack growth and tear resistance of rubber components. The key is to choose the right load class, surface area and structural layer of carbon black. The selected carbon black needs to exhibit good dispersion properties and minimal physical impurities during the complex mixing process to achieve further improvement. The same factors need to be considered when selecting other granular preparations. Filler agglomerates and raw material impurities lead to an increase in the size and number of crack signs of the composite, both of which have adverse effects on fatigue life.

With the development of social economy, domestic and foreign cars are frequently replaced, and the automobile industry is facing a period of rapid change. The development is characterized by further improving the service life of cars under the premise of ensuring driving safety, riding comfort, high-speed driving and luxury. Shock absorbing products are used to control the vibration and noise of the automobile and improve its handling stability, generally placed in the automobile engine frame, pressure rod device, suspension bushing, center bearing bracket, bump limiter and torsional vibration shock absorber and other parts to improve the safety and comfort of the automobile. Shock absorption products can be divided into four categories: bracket, bushing, cushioning and damping, the main requirements of shock absorption, heat resistance and fatigue resistance. Automotive shock absorbing rubber products include engine supports, suspension components, rubber springs, rubber air springs and collision rubber protective parts. In recent years, in order to improve the safety, comfort and operability of automobiles, the variety and number of shock-absorbing rubber products for automobiles have been increasing, such as the number of shock-absorbing rubber products on a car has reached 50-60.   Rubber shock absorbers for the engine and transmission operating system are used to insulate the vibration of the source. Multi-lateral coupling and damping clutch are adopted for shock absorption in transmission part. The shock absorber used on the front and rear suspension device should not only bear the weight of the car body, but also prevent the car body from transmitting the up and down vibration of the wheel, restrain the irregular movement of the unsprung mass, and transmit power and braking force. The rubber buffer is one of the important shock absorbers of the car body. Its structure form is that there is a rubber layer between two metal plates, and the shear deformation of rubber is used to achieve the purpose of buffering. Recently, the cylinder buffer filled with nitrogen and co-existing with shock absorber oil has been developed, which is characterized by improving the load capacity of the buffer (up to 20 MPa), good shock absorption effect, and prolonging its service life. The rubber materials used in automotive rubber shock absorbers are mainly NR and SBR. In order to improve the heat resistance of shock absorber products, IR, IIR, CR, EPDM and so on have been used as the main material. Thermoplastic elastomers will also be used in some shock absorbers, such as body and chassis shock absorbers.

Plexiglass has another common name, called acrylic, I believe that many people are more often heard.   The transparency of plexiglass is very good, and experiments have shown that more than 92% of the sunlight can be passed, and the hardness is very high, and it will not be easily broken. And in the car's headlights and other places are also applied to plexiglass, plexiglass corrosion resistance is also good, will not age in a short time.   The price of plexiglass is also relatively close to the people. And what are the characteristics of plexiglass?   First, highly transparent plexiglass is an excellent polymer transparent material, the solar lamp tube of the artificial small sun is quartz (because quartz can fully penetrate ultraviolet light), ordinary glass can only penetrate 0.6&ultraviolet light, but plexiglass can penetrate 73%.   Second, the relative molecules of high mechanical strength plexiglass are about 2 million, which is a long chain of polymer compounds, and the chain forming the molecule is very soft, therefore, the strength of plexiglass is high after all, and the tensile resistance and impact resistance are 7-18 times higher than ordinary glass. There is a kind of heated and stretched plexiglass, even if the nail penetrates the plexiglass, it will not crack, and this organic glass will not break into fragments after the bullet puncture. Therefore, the stretch-treated plexiglass can be used as bulletproof glass, and it is also used in the cockpit of military aircraft.   The density of light weight plexiglass is 1.18g/cm3, and the same size material, its weight is only half of ordinary glass!   Fourth, easy to process plexiglass can not only be cut with a lathe, drilling machine for drilling, but also can be bonded into various shapes of equipment with imitation, but also can be processed into large aircraft cabin cover, injection, extrusion and other plastic molding methods, small to dentures and dentures and other products.   The application of plexiglass is very wide, and plexiglass is not only in light industry, commerce, chemical industry and so on. Moreover, the application in advertising decoration and sand table model is also very extensive.
