It is said that the silicone material has a big disadvantage is that the toughness is not good, and it is careful to encounter sharp sharps, and with the industry application of all walks of life, the demand for silicone gaskets, silicone flakes and other thin materials is gradually increasing, so the relatively thin product tear resistance has become the trouble of many friends. The silicone gasket purchased is easy to tear and easy to be not durable enough, etc., so combined with various reasons, it can still be identified as caused by several factors!   Tear is the core performance of silicone products, so the tear resistance from the addition of raw material silicone resin in the baking curing process has a great reason! For example, room temperature curing for 24 hours, 130 degrees baking curing difference is relatively large, so the most fundamental reason is the baking time problem, time and temperature do not conflict, but to achieve the same condition of the effect of common, so high temperature baking curing and room temperature curing for a long time will have a great difference, so the raw materials occupy most of the factors! Secondly, silicone products manufacturers in the production vulcanization process, the reason for the tear strength or the production process, the general normal temperature, the normal time can avoid the phenomenon of easy tearing, and in the abnormal processing production time and temperature may cause the phenomenon of poor tearing degree! For example, the staff want to increase the output, the temperature of the machine to reduce the time of vulcanization this method is not feasible for thinner, smaller products, first of all, easy to cause the product is too brittle, poor tear resistance, followed by the mold too early prone to the phenomenon of immature products, so the feasible method is normal processing when adjusted, don't have a lucky mind, easy to bad things!

Are rubber products insulated? Rubber is an insulator. Substances that are not good at conducting current are called insulators, and insulators are also called dielectrics. Insulators can be divided into gases (such as hydrogen, oxygen, xenon, and all non-ionizing gases), liquids (such as pure water, paints, organic acids, etc.), and solids (such as glass, ceramics, rubber, paper, quartz, etc.).   Are rubber products insulated? Most are insulating, but a small amount can be conductive; Rubber refers to a highly elastic polymer material with reversible deformation, which is elastic at room temperature, can produce a large change under the action of a small external force, and can be restored to the original state after removing the external force. Rubber is a completely amorphous polymer, its glass transition temperature is low, the molecular weight is often large, greater than hundreds of thousands. Rubber is divided into natural rubber and synthetic rubber and other two kinds of rubber. Natural rubber is processed from gum extracted from rubber trees, rubber grass and other fine substances: synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life.   Some rubber products are insulated, the general cable rubber, the insulation board of the power distribution room are made of rubber, and some rubber products require a relatively high insulation coefficient, which mainly depends on the environment and application field you use.

Silicone products aging affected by what, silicone products are a common class of products in life, has a very rich variety, can give people help in many areas. Silicone products are the same as some other products, there will be the concept of service life, silicone products will age after a long time of use, and silicone products aging is also affected by some factors.   If the silicone jewelry in the normal use process, the impact of the environment is on the one hand, silicone products are usually subject to oxidation, thermal light, strength, liquid these aspects will have a certain impact on the aging life, after studying the surface of these aspects of the aging of silicone products as follows:   Oxidation: In ozone silicone products with time changes, resulting in the destruction of the material performance is larger, silicone molecular chain compounds are different, resulting in changes in the performance of silicone products, there will be low efficiency to change the material properties of silicone jewelry, you will find that your silicone strap may slowly appear deformation, slow rebound phenomenon!   Photoheat: The influence of photoheat mainly comes from the appearance, long-term exposure to ultraviolet light and light source may lead to the expansion of silicon atoms, the phenomenon of surface discoloration, but there is no change in the short-term exposure to light and heat.   Strength: The impact of the force is more serious, the product long-term tensile extrusion, over time, the silicon molecular chain in the material is damaged and cannot be restored, and there is no resilience after long-term stretching, tensile force decline or even tensile break.   Liquid oil: silica gel is a highly adsorbent material insoluble in water and any liquid, but long-term contact with water will lead to water molecules infiltrating into the silica gel and destroy the basic performance of the material, resulting in a decline in the performance of rubber products and even discoloration, deformation.

Can silicone products be recycled, with the progress of science and technology and the enhancement of environmental awareness, more and more items began to be included in the recycling system, silicone products is one of them. Silicone, as a widely used material, its products can be seen everywhere in daily life, such as baby pacifiers, kitchenware, mobile phone covers and so on. So, can silicone products be recycled?   Silica gel itself is a renewable resource, and its recycling process is relatively simple, mainly through physical or chemical methods to break it down into reusable materials. After the recovered silicone is processed, it can be used again to make new silicone products, so as to achieve the recycling of resources. This not only reduces the need for new resources, but also reduces the environmental pollution caused by the production of new silicone products.   However, it is important to note that not all silicone products can be recycled directly. Some silicone products may have other materials or additives added, making their recycling process complicated. In addition, the recycling of silicone products is not currently popular in all areas, and some areas may not have established a perfect recycling system. Therefore, for the recycling of silicone products, we need to judge and operate according to the specific situation.   In the process of promoting the recycling of silicone products, in addition to the need to establish a more perfect recycling system, it is also necessary to improve the public's environmental awareness and participation. Only when more people realize the importance of silicone products recycling, and actively participate in the recycling action, the recycling of silicone products can be better promoted.   Silicone products can be recycled, which is in line with our environmental protection concept and sustainable development strategy. In the future, with the progress of technology and the improvement of environmental awareness, I believe that the recycling of silicone products will be better developed and improved, and make greater contributions to protecting the environment and saving resources.

Silicone products, as a widely used in medical, home, baby products, kitchen utensils and other fields of material, its antibacterial performance has been concerned.   First of all, silicone products have natural antibacterial properties. The silicone material itself has a certain antibacterial effect, which can inhibit the growth and reproduction of bacteria. This is due to the microstructure and chemical properties of the surface of the silica gel material, so that it has a certain repulsive effect on bacteria. In addition, the silica gel material also has good permeability and hygroscopic properties, which helps to reduce the environment for bacterial breeding.   However, it should be noted that the antibacterial properties of silicone products are not absolute. Although the silicone material itself has a certain antibacterial effect, in practical applications, its antibacterial effect will be affected by a variety of factors. For example, the antibacterial properties of silicone products will gradually weaken with the increase of use time; At the same time, if the silicone products are not kept clean and dry during use, it is also easy to lead to bacterial growth.   In order to further improve the antibacterial properties of silicone products, manufacturers usually use some special treatment processes. For example, the silicone material is treated with antibacterial agents to enhance its antibacterial effect; Or using nanotechnology, a layer of antibacterial film is formed on the surface of the silicone material, so as to more effectively inhibit the growth of bacteria.   In the medical field, the antibacterial properties of silicone products are particularly important. For example, medical supplies such as silicone catheters and silicone pacifiers need to have good antibacterial properties to reduce the risk of infection in patients. In addition, in the field of home and baby products, the antibacterial properties of silicone products have also attracted attention. Silicone baby bottles, toys, etc., can effectively reduce the growth of bacteria and protect the health of infants.   In general, silicone products have certain antibacterial properties, but in practical applications, it is still necessary to pay attention to keep clean and dry to give full play to its antibacterial advantages.

How to distinguish inferior silicone products? In recent years, silicone products are favored by consumers because of their environmental protection, non-toxic and durable characteristics. However, the quality of silicone products on the market is uneven, how to avoid the trap of "toxic silicone" and buy safe and assured silicone products?   1. look at the appearance and feel   1. The surface of high quality silicone products is smooth, no burrs, impurities; The surface of inferior silicone products is rough, or there are obvious particles and scratches. 2. High quality silicone products feel soft, moderate elasticity; Poor quality silicone products feel hard, poor elasticity, and even easy to break.   2. Smell   1. High quality silicone products have no obvious odor, or only light rubber taste; Inferior silicone products have pungent odor, such as sour taste, kerosene smell. 2. Fire test: fire high-quality silicone products, the flame is blue, smokeless; Fire inferior silicone products, the flame is yellow, there is black smoke.   3.check the product certification and certificate   1.High quality silicone products should have relevant certifications, such as ROHS, Reach, etc., and accompanied by certification. 2. Inferior silicone products are often unable to provide relevant certifications and certificates.   4.understand the production process   1. High quality silicone products adopt production processes that meet national standards, such as hot pressing, injection molding, etc. 2. Inferior silicone products are backward in production process, such as manual pressing and low pressure injection molding.   5. Experimental test   1. Dripping test: the water drops on the surface of high-quality silicone products, the water beads are spherical, not easy to penetrate; Poor quality silicone products water diffusion, easy to penetrate. 2. Wear-resistant test: Wipe high-quality silicone products with sandpaper, no obvious surface wear; The surface wear of inferior silicone products is serious.   6. After-sales service   1.High-quality silicone products manufacturers to provide perfect after-sales service, including return, repair, etc.; 2. Manufacturers of inferior silicone products often have no after-sales service, or pass the buck.

Silicone buttons and other keys, as long as the product is needed to use the button, then the silicone button can be useful, for example; "Remote control button, instrument and equipment button, electronic dictionary button" including all electronic products can be used, then do you know, what makes the silicone button into a conductive silicone button, and how do we identify what is a conductive silicone button, the next small series will give you details.   In conductive silicone keys are usually divided into two conductive materials: 1, (conductive black particles) principle: the contact between conductive particles, forming a conductive path, so that the conductive adhesive has electrical conductivity, the stable contact between the particles in the adhesive layer is due to the conductive adhesive curing or drying caused. Before the conductive adhesive is cured or dried, the conductive particles are separated in the adhesive, and there is no continuous contact with each other, so they are in an insulating state. After the conductive adhesive is cured or dried, the volume of the adhesive shrinks due to the volatilization of the solvent and the curing of the adhesive, so that the conductive particles are in a stable continuous state with each other, and thus show electrical conductivity. 2, (ink conductive) electrically conductive printing ink (electrically conductive printing ink), paste ink made of conductive materials (gold, silver, copper and carbon) dispersed in the binder, commonly known as paste ink. It has a certain degree of conductive property and can be used for printing conductive points or conductive lines.   Ways to distinguish silicone buttons from conductive silicone buttons: 1, the black conductive silicone key identification method, to see whether there is a black dot at the bottom of the key, and the dot must have a certain thickness, there are also some dots with texture, if one of the two conditions is met, then the black conductive silicone key. 2, ink conductive silicone key identification method, is also to see whether there is a black dot at the bottom of the key, and the dot is particularly thin, and some form a small black block with the shape of the bottom of the key, which can not be deducted with the nail is the ink conductive silicone key.

There are indeed many rubber raw materials for oil seals, such as nitrile butadiene rubber, fluorine rubber, hydrogenated nitrile butadiene rubber, silicone rubber, AEM and so on.   However, which raw materials to use as oil seals are selected according to the requirements of the use of oil seals. The use of oil seal environment is hot oil state, need temperature resistance, oil resistance.   1, silicone rubber is not oil resistant, does not meet the requirements, eliminated; 2, if the temperature of the working part is low, generally within 120 degrees, NBR is optional, and the relative price is also suitable; 3, if the temperature exceeds 120 degrees, you need to choose ACM, but its gasoline resistance is not good, processing problems are more, compression time will be long deformation. Oil seals made of ordinary ACM materials are prone to oil leakage under high-speed operation. Consider using AEM. 4, if the requirements are higher, the cost is more relaxed, fluorine rubber is the best choice. Now fluorine rubber raw rubber on tens of yuan, such as the cost constraints are basically solved, fluorine rubber cost-effective. 5, if the requirements are higher, such as the seal inside the oil well, you can only use hydrogenated nitrile rubber.

Silicone products how to remove odor, silicone products with its excellent high temperature resistance, oxidation resistance, wear resistance and other characteristics, widely used in daily life and industrial production. However, some silicone products may produce unpleasant odors after they have just been produced or stored for a long time. The smell of silicone products will affect the user experience of consumers.   The odor of silicone products comes from a variety of sources, which may be caused by factors such as residues in the production process, the smell of the material itself, and the pollution of the storage environment. In order to remove these   1.we can start from the following aspects: First, cleaning treatment Cleaning is the first step to remove the odor of silicone products. The use of mild detergent and water, the thorough cleaning of silicone products, can remove surface dirt and residue, thereby reducing the source of odor. Be careful not to use too strong cleaning agents or chemical solvents during the cleaning process, so as not to cause damage to the silicone material.   2.ventilation and drying The cleaned silicone products are placed in a well-ventilated place for drying, which can effectively remove the residual odor. The ultraviolet rays in the sun have a certain bactericidal effect and can help eliminate odors. At the same time, a well-ventilated environment also helps to discharge harmful gases outside and reduce the production of odors.   3. Use activated carbon Activated carbon is a substance with strong adsorption capacity that can remove odors and harmful gases from the air. Placing silicone products in containers filled with activated carbon can speed up the removal of odors. It should be noted that the adsorption capacity of activated carbon is limited, and it needs to be replaced regularly to ensure the effect.   4. Use vinegar water Vinegar water is a natural cleaning agent, and it also has a certain effect on removing the odor of silicone products. Soak the silicone product in diluted vinegar water for a period of time, and then take it out to dry. The acidity of vinegar water can neutralize the alkaline substances on the surface of silicone products, thereby reducing the production of odor.   5.the use of professional deodorant For some stubborn odors, we can consider the use of professional deodorant. These deodorizers usually have a stronger odor removal ability, and can be targeted for the odor of silicone products. When selecting odor remover, we need to pay attention to the selection of good quality, safe and reliable products, and operate in accordance with the use methods on the instructions.

Silicone products are widely used in many fields because of their excellent heat resistance, corrosion resistance and good elastoplasticity. As an important physical property index of silica gel products, hardness has a significant impact on its application effect and service life.   First, the development of hardness standards of silicone products   The development of hardness standards for silicone products is mainly based on the relevant standards issued by the International Organization for Standardization (ISO) and the American Society for Materials and Testing (ASTM) and other authoritative bodies. These standards specify the test method, grade division and qualification range of silicone products hardness, and provide clear guidance for producers.   Second, the grade division of the hardness standard of silicone products   The Hardness standard of silica gel products is usually measured by Shore Hardness, which is divided into three grades: Shaw A, Shaw C and Shaw D. Shaw A is mainly used to test softer silicone products, Shaw C is suitable for medium hardness silicone products, and Shaw D is suitable for harder silicone products. Within each grade, it is divided into several different numerical ranges according to the size of the hardness value to represent different hardness levels.   Third, silicone products hardness standard application guide   Silicone products with different hardness have different application scenarios. Low hardness silicone products are suitable for occasions requiring high elasticity and softness, such as seals, non-slip pads, etc. High hardness silicone products are suitable for occasions that require greater pressure and wear resistance, such as guide rails and support parts.   When choosing silicone products, the appropriate hardness level should be selected according to the specific use requirements and scenarios. For example, for silicone products that need to withstand long-term pressure, materials with higher hardness should be selected to ensure their wear resistance and stability; For silicone products that need to be in contact with the skin, materials with lower hardness should be selected to ensure its comfort and softness.   It should be noted that the hardness of silicone products is not the harder the better or the softer the better, but to make a reasonable choice according to actual needs. Hard silicone products may lead to increased brittleness, fragile, and too soft silicone products may affect its load-bearing capacity and service life.   In addition, for the same silicone product, its hardness may be affected by factors such as temperature, time and environment. Therefore, in the application process should pay attention to the change in the hardness of silicone products, and make corresponding adjustments and maintenance.
