Products such as jewelry protective covers basically go through the oil injection process in the market, and the problem of poor hand feeling will not occur after being used for a long time. It is difficult for us to observe the effect of oil injection with naked eyes, but there is still a difference between hand feeling and touch. The main characteristics of oil-injected products are smooth hand feeling, high surface finish, flat face, no sticky dust, improved wear resistance and strong adhesion. As we all know, a good product must first come from the outside to the inside. Whether it is a silicone product or a hardware and plastic product, all craft products are colored, so how to realize such colors needs to be matched, and how to make them complement each other, how to change the color of silicone products, and the color of good silicone products will also be very unique, there are many beautiful and bright colors in silicone products. How do these colors come true. Every silicone product needs to start from the modulation color, whether it is silicone kitchen utensils, silicone bib, silicone liquid silicone keys, silicone electronic accessories, silicone daily miscellaneous parts and other silicone products, or other technological products, all need this link, unless it requires the transparent color of silicone itself, but this is really rare, and the color of silicone itself is clear. Modulating color is a very professional problem, and it is also a job with a lot of technical content. In color science, mixing different colors to obtain another color is called hue change. Only by mastering the hue change first can the target color be modulated more quickly. There will be a big problem when there is a step difference in one process in the work. Silicone bracelet is no exception. There are many differences before and after oil injection. Oil injection is unknown to many friends. He mainly applies a layer of paint to the surface of the product in the industry to make the customer feel more comfortable. However, the difference in the process of a product on hand-sensitive oil is really very large. The effect of oil injection mainly lies in silk screen printing and pad printing in the rubber and plastic industry, oil injection effect, secondly, oil injection has a good effect on dust prevention and anti-sticking performance of silicone products. The reason why some friends of silicone products stick to dust for a long time is the problem of hand-felt oil. For silicone jewelry, there is a problem with the jewelry of many friends. After a period of time, the product is not as good as before, and the hand feeling is not as good as before, and it will feel a little sticky. In fact, this is caused by the silicone product manufacturer's failure to inject oil into the product, while this is generally not the case with high hardness products, silicone buttons think that some of our special silicone rubber or industrial products with high hardness requirements will not appear this phenomenon.

What if you produce elastic silicone products?

For the transformation and transformation of silicone in the 1980 s and 1990 s and the continuous research and development of technology, silicone rubber products have changed in a certain sense in the society. As far as I know, silicone rubber products have just started in China in the past nine years. In the past, industrial accessories made of rubber were used, and many auto accessories made of sealed silicone keys were replaced by silicone products, because of the outstanding performance and the idea of environmental protection, the silicone rubber products were replaced. The elasticity of silicone rubber products has always been involved in the technical level. Many silicone products need such a parameter to measure the feasibility of the product. From the internal structure of silica gel, it is mainly that some small holes are closely arranged together, and then the sealing ring is combined into a whole. These small holes are embedded and interacted with each other by molecular structure. However, since silica gel is a kind of synthetic rubber, it is necessary to mix silica gel into a kind of mixed rubber before processing and molding. The mixed rubber is roughly the same as the original silica gel structure, except that some substances that will not affect its own performance are added. Under normal circumstances, before the production of silicone rubber products, are added vulcanizing agent, color glue, etc., and the main characteristics of this vulcanizing agent on the liquid silica gel is a reduction catalyst, in fact, the raw material itself on the elasticity of the finished product It does not have much influence, mainly the addition of some other substances will play a specific role. Then, what affects the characteristics of the whole product is the product structure. The softness of silica gel itself is an advantage of creating this characteristic. For example, if the structure of such products as silica gel buttons is not adjusted well, the material cannot be changed or adjusted. The elasticity of the whole product. When someone asks: "Do you know about silicone rubber products, do you know about silicone rubber products," whether you can touch and send them a satisfactory answer, with the continuous reduction of resources, the environment and the change of science and technology, silicone rubber products can bring what kind of value to the society. No one can know the value of rubber and plastic since it was discovered in the early days, but it has been used in some playthings, rubber balls, etc. Silicone products have not been widely used in the early days when silicone was gradually developed with the change of time. Subsequently, it has been widely used in military since the rise of silicone in the 1940 s.

However, the appearance of many products on the packaging is the main reason to attract consumers to buy. Nowadays, many silicone product manufacturers have reduced the cost performance of their products because of an inconspicuous small package. Obviously, a relatively high-quality product has been destroyed in a package. Therefore, don't save costs, cheap and no good sealing ring goods, and blind selection of packaging bags is not acceptable. Whether the surface of the product is smooth or not is directly related to the mold. The quality of the mold directly affects the quality of the product. Then the silicone products must be prepared before production. How should the mold be handled to produce smooth and clean products. To produce high-quality silicone products, preparation work is very important. The preparation of liquid silicone molds and the preparation of raw materials need to be done as fully as possible. The first is to sandblast your mold. Sandblasting is a fine job. It is mainly to rinse the surface of the silicone product mold with fine sand under high pressure to make the mold surface more delicate and clean, and there will be no impurities in the production process, in addition to sandblasting the mold of silicone products, the steps of heating the mold, washing and touching, adding touch pads, etc. cannot be omitted. Silicone products now sales form is grim, in addition to the face of the production process problems, raw materials and mold problems and so on, every detail can determine whether the customer can pay for you, especially in the face of new customers when the details can always determine success or failure. From the appearance of the product to the appearance of the package, there are many details to be dealt with. In the appearance of the product, the matching of color silicone products and the saturation concentration of the color bring very important visual sense to consumers. Therefore, the concentration modulation of color modulation and color masterbatch is very important. Secondly, in terms of hand feeling, people will not feel rough and smooth. In the details of oil injection, it should be carefully checked whether it is comprehensive, whether the raw materials contain sundries or have expired in use, the mold closing line is also a very important point. The burr size of the silicone key offline often affects the main appearance of silicone rubber products and so on.

Many witnessed the trend and decline of silicone keys, as well as the advent of silicone keys for life gifts. In the early years of a few years, a large number of food-grade silicone products came in. Silicone daily products came from European and American countries. Many silicone products manufacturers in the lower reaches of our country changed from silicone keys to daily necessities. Therefore, silicone products for life had to be practical and high-quality, and grinding technology was one of them. Many things are most worried about the phenomenon of product cracking. Of course, silicone products are no exception. On the contrary, the sealing ring is unable to repair and basically scrapped in time after the rubber products are broken. Therefore, as a supplier in the silicone rubber products industry, it is necessary to strictly control this phenomenon. The problems caused by the failure to recover after the silicone rubber products are always annoying. The main phenomenon of man-made rupture: there is a right angle or rupture phenomenon in the use process, which is likely to lead to tear and other phenomena. The main reason is that the hardness of the product is relatively high and the tear property is relatively weak. The main reason is that the liquid silica gel surface on the product surface becomes brittle due to too long oil pressure time under high temperature molding during production and processing by the manufacturer, the phenomenon of high hardness becoming brittle is greater, resulting in right angles or tearing when the mouth is torn. The main reason for the rupture of some silica gel miscellaneous parts is due to the influence of force, and the uneven force at the same time leads to the rupture of product toughness deviation. This phenomenon can select special raw materials and vulcanizing agents from the raw materials of manufacturers to improve the wear resistance and fatigue resistance of products. In addition, the fluidization speed and temperature are normally controlled, and normal operation should be carried out to prevent rupture during use. Silicone material is now a household name. It has played a certain role in life, work and all walks of life. However, don't forget that it can only be loved by consumers if there are other technological help besides itself. Nowadays, there are many production and processing methods for silicone rubber products, but the common hot pressing processing methods for silicone products have long been mature. For products with strict appearance requirements, you need to adopt the appearance treatment method. When early silicone products were immature, most of the appearance treatment methods adopted by the products were manual treatment. The early silicone products and peripheral accessories of silicone products in the early 1990 s all needed to get good material properties and hand feeling properties, such as manual spraying, appearance grinding and manual printing, etc. In the end, grinding and oil spraying have always become one of the necessary processes for many kinds of silicone products, such as daily necessities, female silicone supplies and so on.

The Problem of Shiny Appearance in Mixing Silicone Rubber Products

The Problem of Shiny Appearance in Mixing Silicone Rubber Products

2021-03-20 09:33:24

Due to improper operation, rubber mixing is a technical job. Nowadays, many professional and technical personnel still have not found a mechanical method that can replace the silicone rubber mixing process. The main reason for the silicone rubber key is that the material needs to be clean, environmentally friendly and free of impurities. In the rubber mixing process, the operation mode of the rubber material and the adjustment of the wheelbase may lead to quality problems, such as the difficulty of dispersing high-hardness rubber material, low-quality white carbon black and high-hardness silicone rubber scattered after rubber refining. Silicone protective sleeve is very important to the surface of the appearance, so the requirements for black spots, impurities and burr parting lines are very strict. However, when many silicone products are customized, there will always be a sealing ring problem, and the appearance of the product will be shiny, resulting in uneven face, which will seriously affect the appearance effect. For this kind of imagination, anyone will basically think that this is a defective product, so the product will have shiny surface, how to deal with this problem. The first is the problem of raw materials. The proportion of silicone oil in the raw materials exceeds the proportion, resulting in a large area of color difference during the forming oil pressure. However, this phenomenon does not occur under normal circumstances, and precipitation will gradually become prominent after time. Therefore, the raw materials can be tested for liquid silica gel before production. On the other hand, it is caused by sticking adhesive paper during the process of mixing and cutting. Under normal circumstances, it is easy to mix the adhesive paper into the raw materials when the manufacturers of silicone mobile phone sets cut the raw materials. As a result, the mixed adhesive paper is vulcanized at high temperature on the machine table and melted and stuck to the inside and surface of the product when exposed to heat. Plastic paper is different from silicone raw materials, while silicone does not fuse with any substance, therefore, the shiny surface of the product is likely to be plastic paper, which leads to a high probability of product surface. Mixing rubber processing is a very popular processing industry among organic silicone products at present. At present, solid silicone rubber materials, such as electronic accessories, mechanical seals, daily necessities, etc., can be used in many industries around the world. However, solid mixing rubber is pure in the process. This certain problem is not easy to control, such as bad processing factors, precision quality of molds, purity and mixing of raw materials, can affect the normal production of products. The scorching of the raw materials of silicone rubber products is one of the main reasons. The raw materials also need to be mixed with silica gel products to achieve the physical properties. The uneven addition and distribution of vulcanizing agent accelerator is likely to lead to static electricity and fire in the mixed rubber. Therefore, the raw materials and vulcanizing agent should not be completely put into the high-temperature roller during mixing, which will lead to such problems. Instead, the vulcanizing agent needs to be dispersed and mixed after uniform coating.
