Conductive silicone keys generally use two conductive materials: conductive black particles and ink conductive, so how to distinguish the two conductive silicone keys? 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 this dot is particularly thin, and some are formed with the shape of the bottom of the key - a small black block, which can not be deducted with the nail is the ink conductive silicone key.   When it comes to silicone keys, I believe everyone knows that silicone keys are the same as other keys, as long as the product needs to use buttons, then silicone keys can be used, for example; "Remote control keys, instrument keys, electronic dictionary keys" including all electronic products can be used, then do you know, what makes silicone keys into conductive silicone keys, and how do we identify what is conductive silicone keys?   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.  

Generally, silicone products require insulation and conductivity, so how to distinguish between conductive silicone and antistatic silicone? The surface resistance value of insulating silicone products reaches 10 to the 12th power or more is the insulation level. (There must be many people who think: 10 to the fifth power below is conductive, 5 to the ninth power is anti-static, and more than 9 power is insulation.)   Conductive silicone rubber usually refers to a volume resistance within 9 ohms of 10. Conductive rubber is divided into anti-static grade conductive rubber 1. The surface resistance value of antistatic silicone rubber products reaches 10 to the power of 5-12 between the antistatic level. Within 10 to the 9th power, between 10 to the 6-8 power is permanent but the raw material performance will deteriorate, more than 10 to the 9th power is short antistatic. 2. The surface resistance of conductive silicone rubber products reaches 10 to the fifth power below the conductive level. The volume resistivity is generally 3 ~ 10Ω·cm, the relative density is 1.15, the hardness (Shore A) is 60, the tensile strength is 5.7MPa, and the relative elongation is 265%. It can be made of methyl vinyl silicone rubber (raw rubber), white carbon black, conductive filler, structural control agent and organic peroxide. When the volume resistance is less than 10 ohcm, the conductive rubber has electromagnetic shielding function.

First, the difference from the appearance and feel:   1, the fake silicone rubber wristband is easy to deform, and the real silicone rubber will feel the rebound is very good, and the tensile deformation is small.   2, if the real silicone rubber surface is not specially treated, the hand will feel the contrast lubrication, because there will be a layer of grease on the outer surface.   3, the appearance of silicone rubber is easy to stick to impurities such as dust and hair.   Two.Combustion comparison method:   1. The margin of the fake silicone rubber wristband is black after the fire, and the real silicone burning margin is white no matter what color, and the incineration residue is powder.   2. The fake silicone rubber wristband is burning with open fire, black smoke and foul odor. The real silicone rubber wristband is like carbon burning, and the flame is uniform. White smoke, tasteless.   Third, solution method:   Incinerate silicone rubber and touch the smoke with a surface dish, collect the white powder, dissolve the powder in a hot solution of 40% sodium hydroxide (60 degrees), take a drop of the solution into a test tube, add two drops of ammonia molybdate, gently heat it, cool it, add a drop of aniline solution and 3-8 drops of full sodium acetate solution, and observe the color response of the solution. If it appears blue, it indicates that there is silicon element. Proof is silicone rubber. The above three methods can identify the true and false silicone rubber bracelet for you!

Silicone sealing ring, in the long-term adhesion and metal pressing extrusion, after frequent stress resulting in silicone sealing ring does not rebound, no stress phenomenon, as the manufacturer will tell you how to maintain and long-term use of silicone sealing ring in three angles.   Some seals are used in harsh environments for a long time, such as oxygen, heat, and light under the action of aging phenomenon resulting in phase distortion, so in the early stage for the use of silicone seals environment and time, etc. need to consider whether the material and product can maintain a long-term life, elasticity is not affected and so on. Generally start from these three aspects.   The ambient temperature of the silicone seal ring In the process of use, a variety of high and low temperature is a major factor affecting the product, although the silicone material can accept more than 200 degrees to -40 degrees of high temperature, but long-term suitable for harsh heat conditions will accelerate the aging of the silicone seal ring, the higher the temperature, the greater the deformation of the product will be, and the largest force deformation of the silicone material is generally more than 40% will completely lose working performance. Causes the seal to leak and so on. When used at low temperatures, it is recommended to appropriately increase the compression and tensile degree. When used at low temperatures, attention should be paid to the phenomenon of product necrosis and deformation and rupture.   The tensile degree of the silicone sealing ring Tensile degree is one of the main operating capabilities of silicone sealing ring, so in the production of silicone products manufacturers will choose the corresponding pull strength material and various hardness of the use of conditions, so for long-term repeated use of the demand can choose high tensile silicone material processing production, in order to prevent the growth of products over time and affect the performance of the product, Due to the long-term operation of silicone rubber beyond the tensile range of the use of the case will often make the product become relaxed, lose tension, so in sufficient conditions to reduce the tensile degree of work intervention, long-term use of the biggest factor affecting the deformation of silicone material, so reduce the working pressure is the best way to maintain the seal ring.   Selection of raw materials for silicone sealing rings In addition, high quality materials are used in the performance of the product, and the higher the high tensile and product hardness properties, the better the product quality.

For consumers who do not understand the silicone material, the physical hardness of silicone rubber products may produce an ill-informed mind, the size of the product is the same without too much change, and the relationship between the formula and various physical properties is not complete to understand, all kinds of silicone, rubber and other material raw materials have its hardness and softness characteristics, natural silicone products are no exception, So why silicone material can be used in all walks of life in the world, because of its excellent hardness!   Different silicone products have its unique performance and process requirements, such as silicone silicone seals, silicone accessories, etc., can choose the most suitable polymer and match and reasonable deployment, in the hardness and softness to achieve close adhesion sealing shock absorption, waterproof oil and other effects, and hard and soft physical properties are still closely related to the formula and raw materials of the product. The debugging of the formula can try out various performance differences and functions, so the hardness and softness debugging still need to be careful, otherwise the hardness and softness errors are likely to cause inevitable trouble!   We all know that silicone material has good tensile strength, and the tensile strength of the index depends on the degree of hardness and softness of the product, silicone rubber products manufacturers generally the hardness of the manufacturer is about 20-80 degrees, the lower the hardness of the product tensile strength is better, generally can reach about 300%, the minimum is about 20%, However, it still depends on the structure and shape of the silicone product.   Silicone material is indispensable this is the tearing strength, silicone rubber material will be due to force and other factors and tear phenomenon, this is one of the inevitable phenomena of all rubber, and cracks and cracks caused by force cracking phenomenon occupy a minority, because silicone rubber with conventional hardness basically no tear rupture phenomenon, Materials with higher hardness are likely to tear due to the diffusion of the crack mouth!   Therefore, the tensile force and hardness of silicone products are important indicators of the material, silicone processing manufacturers in the vulcanization production procedures, the greater the silicon molecular weight of the compound, the greater the effective cross-linking fixed elongation stress. In order to obtain the specified constant elongation stress, the crosslinking density of the material with small molecular weight can be appropriately increased. Any structural factor that increases intermolecular forces. Increasing the density of silica gel material can prevent the hardness of the product from affecting the tensile strength of the product!

Some rubber contains unsaturated groups, due to the activity of these groups, sulfur can be used for vulcanization, on the other hand, it is precisely because of the presence of these unsaturated active groups, which makes rubber easy to react with oxygen, ozone and other active substances to break the rubber chain, crosslinking and so on. Even after destruction, diolefin rubber such as natural rubber, styrene butadiene rubber, butadiene rubber, isoamyl rubber, butadiene rubber and neoprene rubber still contain unsaturated groups and are affected by the above factors. The higher the temperature, the stronger the effect of these factors. These phenomena are particularly serious when the rubber is over-sulfur, at which time the free double bond in the rubber can also react with free sulfur to harden the vulcanized rubber, the so-called "post-vulcanization". In synthetic rubber, the material also hardens and becomes brittle due to further polymerization and intramolecular cross-linking (cyclization). Moisture, especially at high temperatures, can break rubber (such as polyurethane rubber) that can be hydrolyzed. In addition, rubber products often appear in the use of the surface cracking, white, physical and mechanical properties decline, these phenomena are collectively referred to as "aging". Rubber aging is not a simple process, but a general term for the decline in the performance of rubber and its products. The main factors leading to aging are thermal oxidation, oxidation with mechanical stress (flexion cracking), ozonation with mechanical stress (ozone cracking), oxidation with light and ultraviolet light (fine cracking effect), oxidation with heavy metal participation (accelerated aging of rubber poisons), hydrolysis of hot water, steam and water (hydrolytic aging), and simple heat Effects (thermal decomposition, post-vulcanization, cyclization, vulcanization reduction) and mold corrosion. In order to make durable rubber products, it is necessary to add some substances that can inhibit the above various aging phenomena in the rubber material, which is generally called "antioxidant". In fact, natural rubber, depending on its manufacturing method, always contains more or less organic substances that can inhibit oxidation (these substances are partly consumed in the vulcanization process). However, it can not meet the requirements of modern technology for the aging properties of rubber products, so it is still necessary to add antioxidants when manufacturing rubber products. Although most synthetic rubber has added some antioxidant as a stabilizer in the manufacturing process, a certain amount of antioxidant needs to be added in the application, especially to protect against ozone and flexor cracking.

There are many silicone products in our lives, and silicone products are also one of the most common supplies in our lives.   Silica gel, also known as silica gel, is a granular porous silica hydrate, which is an amorphous substance with a transparent or milky white appearance. It is made by washing and drying sodium silicate after acid addition. It is chemically stable, non-burning, non-toxic and tasteless. Although the name "glue", it is actually a solid, transparent or milky white appearance. Silicone is sometimes referred to as silicone, but is actually a silicon-containing compound with completely different properties and uses. Generally due to the humidity of the outside world, the temperature causes mold, such as the kitchen, bathroom and other humid places, as well as the hot and humid climate in the south. Of course, in addition to the external influence, the main reasons also include some additives in silicone raw materials, such as silicone oil, color rubber powder, vulcanizing agent and so on. They are the main body of nutrients for these molds to grow. The growth of mold leads to the erosion of plant proteins and carbohydrates in silica gel. In addition, due to the inert and electrostatic effect of silica gel, impurities in the air are adsorbed on the surface of the product, which can also lead to the growth of mold. Generally, silicone products manufacturers have to consider such factors, so the moldy phenomenon of silicone products in addition to the factors of raw materials, mainly to rely on their own control. For example, some silicone tableware should be placed at a tilt after washing, so that water can naturally flow down, and the silicone sealing ring inside the rice cooker, do not immediately install it after washing, and place it in a ventilated place to dry naturally. Moldy silica gel products can be wiped with alcohol to remove moldy spots. If the above methods are difficult to solve, we can also choose to use mildewproof agents to treat, the choice of mildewproof agents should have high thermal stability, good weather resistance, low volatility and good compatibility of materials.      

What is the role of silicone bracelet, silicone products are a very common type of product in life, there are many kinds of excellent functions, and they can give people a lot of help. Silicone bracelet is a very popular silicone products, many people will customize or buy silicone bracelets to wear.   Silicone bracelet used in various casinos, sports venues, can be used as gifts, souvenirs, promotional products, etc., is a hot fashion jewelry; It is also a low cost, high advertising efficiency advertising promotional gifts. Most sports bands have no practical purpose and are just fashion accessories. The English words or expressions on the bracelet often reflect the beliefs and values of the wearer. 1. As a fashion accessory. The color of the silicone bracelet is colorful, and it also comes with fluorescent luminous, which can choose your favorite color and style according to your own preferences. Wear it and then match it with your own clothing can play a very good decorative role. 2, prevent sweat flow to the player's hand caused by the phenomenon of sliding. Because it is made of environmentally friendly silicone, the silicone bracelet can effectively absorb the sweat from the human body and prevent the sweat from flowing to the players' hands causing the phenomenon of sliding. 3.
