The main auxiliary materials for the production of silica gel products, silica gel raw materials, vulcanizing agents, color glue, and the most dominant advantage over the injection molding process is that the cost is lower. Solid silica gel molds are offset from liquid in the industry. The prices of raw materials and liquid are relatively cheap. The cavity of the mold is more than high. The disadvantage is that manual operation is troublesome. The self-splitting mold line is not perfect in liquid state, and the softness of the product is limited to about 20 degrees. In the silicone process, for the silicone products with special shapes and high hardness, which are not easy to bend, the sealing ring hardware package rubber products have become one of the choices of many customers. For example, our common handles are basically made of metal inside and glue outside. This phenomenon can be called partial encapsulation and integral encapsulation. The common products of partial encapsulation are like screwdrivers. The integral encapsulation is silicone spoon, for silicone products manufacturers, the difficulty of using injection molding process for local encapsulation products is still relatively large, so the overall encapsulation effect is basically used to produce. For rubber-coated liquid silicone products, the molding process mainly uses mixed rubber to wrap the hardware into the mold and carry out molding to obtain the overall wrapping effect. However, the appearance of the product and the requirements of the overall wrapping are compared with the products, so the phenomenon of hardware leakage has become a major difficulty in the metal-coated rubber process. As various problems inevitably occur in the rubber-coated rubber, for this reason, the adjustment of personnel and machines in the production process needs different ways to solve. In the silicone industry, all kinds of silicone rubber products can be made from mixed rubber and liquid rubber. The same is that their products are made of silicone rubber materials, which can reach various environmental protection certifications, and can also be made into the same shape and size. The products still have no difference in hand feeling and visual effect, but the difference lies in the difference between the two processing technologies and products of solid silicone and liquid silicone, so what should you choose between solid and liquid. The raw materials of solid silicone rubber products are mainly solidified overall raw materials. During processing, silicone rubber products manufacturers need to use rollers to heat it up to softness (like chewing gum, the finished product is perfectly solidified and chewed with soft edges). During processing, a molding curing agent is added, and a mold is used to put rubber into a flat vulcanizer at high temperature for molding to obtain finished products with different hardness.

Thermal vulcanization experiment is the main process for silicone product manufacturers to detect product aging and temperature resistance. Silicone keys put rubber material and silicone material into an oven for vulcanization for four hours at the same time. Generally, rubber will have obvious smell and rebound. Excessive hardness will also cause fracture. Silicone can completely remove the taste and discharge the amount of debris inside the rubber material to achieve complete food-grade silicone product material. In life, many products have a little problem but it is very headache, such as many sealing products, etc. Many times, the sealing rings and silicone fittings used in life have aging and failure of sealing rings, which affects their service life. The more common joint seals and pipeline sealing rings, etc. A small sealing fitting is broken but affects the overall usage. Therefore, it is more important for silicone sealing rings to purchase, otherwise, it will seriously affect the whole product. For silicone sealing products can be seen everywhere in life, such as water pipes, drinking fountains, switch valves and so on, so its adhesion and tightness of liquid silicone is still very important. When it comes to quality problems, aging and life make it seriously affected, so in addition to the use of various environments, the selection of material standards is also very important. First of all, whether the raw materials are qualified, and secondly, whether the vulcanizing agent added to the rubber mixture raw materials is qualified, and the main reason why the silicone products are affected by aging is caused by the raw materials, such as light, heat, oxygen, liquid and so on. For professional people, judging the material problem of silicone products is at a glance, but for new friends, it is difficult to distinguish the difference between rubber, silicone rubber and other rubber materials. However, there are many kinds of materials in the rubber category, and professionals sometimes cannot completely judge which one it belongs. The material is distinguished by performance and weight. When two identical products are obtained, it can be analyzed by weight whether it belongs to silicone rubber or which kind of rubber. Generally, the density of rubber is roughly the same, while the weight of silicone is relatively low, depending on the proportion of white carbon black added. Secondly, the material is soaked in oil for 48 hours. The rubber is generally NBR and EPDM,SBR and other three materials will be intrusive to increase weight, silica gel will not change.

The phenomenon of small products becoming brittle and soft is a relatively common phenomenon in the molding process of silicone products, and it is also a relatively distressing phenomenon. Many silicone product manufacturers become brittle and brittle in the production process, and they break when pinched, resulting in many bad problems in our production, seriously affecting our production efficiency, even if the products can barely pass QC sealing ring detection, the service life in the market can not meet the reasonable time requirements. 1. The first is the problem of production. The temperature is too high and the time is too long during molding and processing, which leads to brittle products, poor secondary vulcanization and ventilation for too long, material problems, and the main reasons for brittle or hard silicone products caused by materials are that the material itself is not good, resulting in substandard tear strength. 2. The unreasonable design of the mold and the unreasonable production structure of silicone products, the unreasonable structure of the liquid silicone product or the mold design of the product lead to fracturing of the mold product during production. It is suggested to improve the processing of the mold or the structure of the mold, and slightly thicken the thin place, slightly round the right angle, etc. 3. The most common reason is mainly caused by the operation method of personnel. Generally, silicone rubber product manufacturers will lock the vulcanization time in a time during the production process. Only when the mold time is well controlled can the product become brittle and soft. With the trend of the electronic product market, everyone is familiar with the current electronic protective cover and belongs to a very rising protective product. The selection of silicone material is not only a single choice of appearance, but also not inferior to other materials in quality, bringing more convenience to consumption. Everyone knows that a product has certain defects, so what factors are limited to the quality of silicone products. 1, silicone products tensile rebound strength: tensile strength is the root of rubber and plastic products, mainly refers to the silicone material in the tensile is what basic conditions, in different range of units to reach a certain standard, and silicone electronic protective sheath can get a certain degree of flexibility to achieve a good anti-fall shockproof effect. 2. Hardness and softness: Silicone rubber raw materials have certain different hardness and softness, which can be divided into 30-80 degrees. It can be applied to silica gel protective cover to a moderate extent. Under normal circumstances, the force and hardness and softness of silica gel have certain factors due to silica gel keys. If the hardness is too high, it is too brittle and does not rebound. If the hardness is too low, it is too brittle and easy to stick to dust.

Silica gel key leaching residue after acid leaching of cesium by Gulu silicic acid, due to leaching of iron and manganese and other elements, whiteness is improved, and due to leaching of various alkaline components, SiO2 content is also increased compared with silica, making it closer to the requirements of high silicon and low iron for SiO2 raw materials for sodium silicate, white carbon black and activated white carbon black. The total adverse phenomena in the processing of silicone products will bring great losses to the company, and the most special one is a kind of products with large sealing ring size and long processing time, which not only consumes a lot of raw materials, but also has a certain impact on time and energy. Therefore, the quality problems of silicone materials except molds, the phenomenon of dark marks often bothers us that we can't deliver the goods, so do you know what causes dark marks on silicone products. First of all, the reason for the dark marks or lines in silica gel products is not only caused by the vulcanization process, but also liquid silica gel has certain influence on rubber mixing, raw materials, mold structure and steel, etc. However, most of these products are included in white silica gel protective sleeve, flat back cover protective sleeve and overall area when the products are relatively large and the appearance is obvious and the color is relatively bright. In terms of color, the temperature of the roller and the proportion of color glue are not reasonably mixed during the mixing process. The most important thing is the control of the mixing time. The main reason for the appearance of material lines in the products of many silicone product manufacturers is that the rubber is not evenly mixed during mixing. Silica is the most important reinforcing agent for raw materials of silica gel products. In addition, it is also an indispensable raw material for rubber, plastic, paper making, coating, ink, paint making and other industries. Therefore, it cannot be ignored in quality. Many silica gel products commonly used by us must come from it. Therefore, there is a detailed analysis of material requirements and product performance. What is the processing of silica and how is it made. Most of the silica is supplied by foreign countries. Foreign countries not only produce large amounts of silica, but also silica gel products are developing into various inorganic fine chemical products. There are more than ten domestic manufacturers, and most of the silica produced are used for silica gel and rubber reinforcing agents. In recent years, with the improvement of people's living standards, the product structure of the rubber industry has undergone new changes. The amount of black rubber is decreasing day by day, replacing it with light colors and colors, the demand for transparent or translucent silicone rubber products is increasing day by day, so the market demand for silica is increasing rapidly.
