Conductive black particles. These conductive black particles are the most common and most common, found on many buttons. They are usually round with a grid pattern and have a resistance of around 100Ω. The shape can also be customized, requiring an additional black die for punching. Conductive ink. With conductive materials (gold, silver, copper and carbon) dispersed in the binder made of paste ink, has a certain degree of conductive properties, when the ink drying is poor, resistance value will increase, so also need to bake under infrared. Gold-plated grains. Conventional conductive black particles have a resistance of around 100Ω, while gold-plated particles can keep the resistance within 1Ω. The lower the resistance value, the higher the sensitivity of the key, therefore, gold plated particles are often used on the silicone button with higher sensitivity requirements. Such as military keys, car keys, instrument silicone keys and so on.....

Since transparent silica gel products are transparent how possible yellow, yellow can be transparent, what reason is that caused? Is it oxidation? Normal transparent silica gel products are put for several years will not yellow, but sometimes we are in production, some transparent silica gel products just out of the oven will yellow, the transparent silica gel products why yellow? The main problem lies in the following aspects: I. vulcanizing agent 1 vulcanizing agent performance is divided into common type and yellow resistance. Its application scope has the following two aspects: 2. Common type of non-yellow vulcanizing agent, used in some can be used for color is dark or the color is not high requirements of non-exposed silica gel products. 3. Anti-yellow vulcanizing agent should be used in products that need to be exposed, light and bright color, and have high requirements for color. The quality of vulcanizing agent is highly correlated with hydrogen silicone oil. Dow Corning contains hydrogen silicone oil with hydrogen value above 1.6. Acid value below 1, the effect is better. Two. The process Transparent silica gel products in the forming, leading to transparent silica gel products in the forming after the color of yellow main problems are: 1. The mold temperature is too high; 2. Too long curing time; 3. After adding sulfur twice. The raw material itself is of poor quality Sometimes we add anti-yellow vulcanizing agent in the rubber compound, but the transparent silica gel product still looks yellow after molding. It may be that the anti-yellow ability of the raw material is too poor. The raw material is suggested to be directly refueling. Conclusion: Although silicone products have excellent weather resistance and aging resistance. But sometimes the silicone products that have just come out of the oven turn yellow. In order to avoid this situation, according to the requirements of the selection of vulcanizing agent, process to strictly control the temperature of the mold and product vulcanization time, raw materials should pay attention to the yellow resistance of raw materials.

1, silicone keyboard has environmental protection, non-toxic tasteless, and good elasticity; 2, wear resistance, high temperature resistance, no deformation and other characteristics, can be used for a long time; 3, smooth appearance, feel strong, is a real green environmental protection products; 4, can do monochrome, two colors, three colors and other colors mixed; 5, the LOGO on the jewelry can be text, pattern or the combination of text and pattern. Silicone key production process Silicon is high temperature vulcanized rubber as the main raw material by molding molding process and the production of silicone rubber products. A finished silicone key needs to go through the following processes: First, raw material preparation (also called mixing glue, material preparation, etc.) : including raw glue mixing, color matching, raw material weight calculation, etc.; Two, curing molding (also called oil molding) : using high pressure curing equipment after high temperature curing, so that silica gel raw materials into solid molding; Three, the peak (also known as processing, burr, etc.) : silica gel products removed from the mold will be associated with some useless burr, hole debris, need to be removed; At present, in the industry, this process is completely completed by hand, some factories are also useful punch to complete; 4. Screen printing: This process is only used in some silica gel keyboards with patterns on the surface, such as English letters and Arabic numerals on the silica gel keyboard. In order to facilitate the user to operate the keys, it is often necessary to screen print the corresponding characters corresponding to the mobile phone keyboard in the corresponding position; Five, surface treatment: surface treatment including dust removal with air gun; Six, oil injection: silica gel keyboard in the ordinary state is easy to absorb the dust in the air, and has a certain viscosity. Spray a thin layer of feel oil on the surface of the silicone key, which can not only prevent dust but also ensure the feel; 7. Others: Other processes include some additional functions given by the silicone keyboard by the business, such as glue dropping, radium carving, P+R synthesis, optimized packaging, and assembly of other materials and components.

Silica gel keys are easy to absorb dust under normal circumstances, so in the production process, to spray a thin layer of feel oil on the surface of silica gel keys, which can prevent dust and make the feel better. Injection technology is mainly based on customer requirements to modulate different feel and appearance of silica gel keys, but silica gel keys injection also has three different processing methods. 1. Spray color oil: Spray color oil is originally in the appearance of silicone keys spray on a layer of visible ink, color is according to customer demand for goods to adjust. 2. Extinction: I believe that many people have been very familiar with the extinction ink, extinction ink is a fog surface feel ink, its characteristics and PU ink contrast is similar, but the extinction ink will make the silica gel button appearance of fog surface, and can spray the effect of abrasive, feel is also more smooth than! 3. The spray PU: PU refers to a kind of ink, it has the characteristics of strong adhesion, wear resistance, good transparency and so on. The silica gel keys sprayed with PU feel is also very good, very wear-resistant, and it is also a common injection of silica gel keys The above three are commonly known as the "oil injection silicone key", and some people say spraying, spray painting.

Silica gel products are a kind of silicone rubber, belonging to a single component room temperature vulcanized liquid rubber products. Once EXPOSED TO AIR, THE SILANE MONOMERS ARE CONDENSED, FORMING A NETWORK STRUCTURE THAT CROSS-LINKS THE SYSTEM, CANNOT BE MELTED AND DISSOLVED, IS ELASTIC, becomes RUBBERY, AND BINDS THE OBJECT TOGETHER. Its thermal conductivity is slightly higher than the general rubber products, once cured, it is difficult to separate the adhesive objects. A highly elastic polymer compound for rubber products. Includes both unvulcanized and vulcanized varieties. Can be divided into natural rubber products and synthetic rubber products two categories. Natural rubber is processed from latex obtained from rubber plants. Synthetic rubber products are prepared by polymerization or polycondensation of monomers. Unvulcanized rubber products commonly known as raw rubber products or raw rubber. Rubber products that have been vulcanized are called vulcanized rubber products, commonly known as rotted rubber products or rubber. Widely used in the manufacture of tires, rubber hose, tape, insulation materials, rubber shoes, and other rubber products, etc.

Summer is a season with the highest number of high temperature days in a year, with the temperature continues to rise, the intensity of ozone and ultraviolet light is getting higher and higher, resulting in rapid aging of silica gel products, resulting in reduced life of silica gel products, so how to prevent the aging of silica gel products in summer? 1. Prevent silica gel products from being placed in ventilated and dry places and avoid direct exposure to sunlight; 2, put water inside the bubble for a while, because silica gel has strong hygroscopic ability; 3, on the surface coating of silica gel products or add light shielding agent, add paraffin and other treatment to avoid premature aging of silica gel products; 4, 1% is added in the silicone products of amine or phenolic additives, can effectively protect from heat, oxygen, light, and the effect of fluid, for the silicone products, silicone products will have a storage period of raw materials, has a great relationship with temperature, if the temperature is about 20 ° C, the silica gel products generally can be stored for three years there was no problem. If stored at 35°C-40°C temperature, it is likely that the silica gel will stick together in less than a year, so try to use silica gel products within the specified period. In the summer we need to often check silica gel products, if there is cracking, adhesion and other phenomena need to deal with quickly, do a good job of maintenance measures can ensure unnecessary losses, can also ensure the use of silica gel products time.  

In the usual use of silica gel products, no matter whether the hardness of the product does not meet the requirements can not guarantee the normal use of the phenomenon, which is not in line with the local phenomenon of the hardness of silica gel products is very different from the manufacturer's production of hardness. The main reason is some problems in the molding curing process, and in the case of ensuring the hardness of the raw material of the product, it can basically be obtained from the machine equipment and personnel control. Recently, many friends have reported that their electronic buttons have such products. Due to the hardness and softness of the button, the toughness of the button is not good enough, and there is no rebound phenomenon after the installation. This situation is caused by the production reasons of the silicone product manufacturers themselves. The raw materials and machinery and equipment are guaranteed to be normal, that is, the production of personnel and the problem of The Times. Generally, the silicone product manufacturers will need to confirm how many degrees of raw materials are mixed in the samples required by the customers to ensure that the hardness requirements of customers meet the standard. After mixing, the temperature of the machine and equipment is adjusted from the pressure and drain hole. It is necessary to determine the curing time to achieve the most desirable results, so after complete inspection, the reason can be identified from the method of operation. For product hardness, it does not need to be too hard or too soft. Usually, silicone rubber products will be adjusted from time to time, and it is necessary to make more appropriate products to adjust the time. According to the previous model of the product, can realize whether the product reaches the hardness. If adding two or three degrees of mold temperature is not enough, the time will be extended. If the hand feels too hard and not too brittle, it will lead to easy cracking in the actual process in the future. You can reduce the time to increase production time. Too brittle, then only lower the temperature until the bubbles are not good. The hardness of silicone products may seriously affect the normal use. Therefore, when the manufacturer produces, try to make the product soft to achieve the best feel, hard and soft. Moderate seating.  

Silica gel according to its properties and components can be divided into organic silica gel and inorganic silica gel two categories. Inorganic silica gel is a kind of highly active adsorption material, organic silica gel is a kind of organic silicon compound, is the most used category, accounting for about 90% of the total dosage. Silica gel is also a kind of rubber and plastic material, because the material is superior in the production process when relatively simple, the cost is lower than plastic in the process, the outstanding advantage is that it is non-toxic and environmental protection products, there is no conflict on the body, the disadvantage is that the air permeability is not good, will produce electrostatic adsorption force is too strong. 2, belong to our common PU plastic material, PC material, such as when the manufacturer production using extrusion process, molding, blow molding process, the main advantages are wear-resisting, oil resistant, transparency, good elasticity, excellent electrical insulation, extensibility, dimensional stability and resistance to chemical corrosion resistance, heat resistance and cold resistance, also has the advantages of self-extinguishing, flame retardant, can be colored. Plastic parts design must make injection mold processing simple, low cost, at the same time parts injection molding time is short, high efficiency, parts defects less, high quality, this is the design of injection molding processing. Different from silicone rubber products is the problem of coloring, in the deployment of solvents at the same time part of polyvinyl chloride is not equal to the compound in the case of the release of harmful substances to secrete interfering chemicals, endangering the safety problem. Silica gel and plastic: one is thermosetting polymers, one is a thermoplastic polymer silica heating can't again and again with molding, was not in the solvent to dissolve plastic flow deformation can occur during heating, cooling after can keep certain properties of shape, easy for extrusion and injection or blow molding, forming, in a certain temperature range, can be repeated heating and cooling hardening. 1. Food grade silicone is tasteless, most of the plastic has smell; 2. Compared with plastic, silica gel has more stable chemical properties; 3. Silica gel can be degraded, plastic can't; 4. Silica gel aging resistance, long service life, relatively much worse plastic; 5. Silicone performs better than plastic in terms of anti-skid, fading and tear resistance; 6. Temperature resistance: silicone high and low temperature resistance (-40℃-230℃), plastic (100-150℃); 7 silica gel in the combustion performance: non-flammable; Plastics, on the other hand, are flammable and produce harmful substances. The difference between silicone and plastic: 1, non-toxic and tasteless: no silica gel, most of the plastic; 2, physiological inertia, chemical stability: silica gel is high, plastic is general; 3, environmental protection and degradation: silica gel can, plastic can't; 4, aging resistance, service life: silica gel can, plastic can't; 5, soft/flexible: silica gel is better, plastic is bad; 6, anti-slip, shockproof, elasticity, insulation, tear resistance, anti fading: silica gel is better, plastic is bad; 7, temperature resistance: silicone high and low temperature resistance (-40℃-230℃), plastic (100-150℃) 8, combustion performance: silica gel is not flammable, will not produce harmful substances, plastic flammable, produce harmful substances;
