What if the problem of cracking of silicone rubber products is solved?

What if the problem of cracking of silicone rubber products is solved?

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.

The advantages of silicone gifts we basically know, durable, with many, cheap and easy to clean, and now we say the shortcomings, silicone watchband is easy to aging, according to the temperature and there are different degrees of fracture, hardening, softening, discoloration and other phenomena. Silicone rubber material looks at the silicone key is relatively low in price and has no high value content of other materials. If it breaks and cannot be remedied, it can only be replaced. If it is worn for a long time, it is also easy to fade. With the popularity of the green environmental protection market, environmentally friendly silicone rubber has become a part of our life and work, with a wide range of functions beyond your imagination. At the same time, silicone products have gradually replaced many items in our life. For example, in the small gift industry of promotional gifts, silicone sealant gifts have gradually become one of the first items in modern promotional gifts, especially gifts at event sites, shopping mall event items and large-scale dinner event gifts, etc, however, the "how to buy silicone gifts" has become a real normal problem, can not find the desired effect and the desired quality and other factors. First of all, the standard is very important, any industry we need to have in line with the industry standard, and silicone rubber products and silicone liquid silicone rubber promotional gifts industry standard is the following points:. 1. Appearance of the product: The black dot hybrid affects the surface appearance of the product, and the inconsistent mold surface of the product affects the appearance effect. The product has mixed colors, the color difference leads to poor appearance, and the production and processing leads to poor appearance. 2. Product quality problems: mainly due to lack of glue during molding and vulcanization, soft or too brittle products, internal bulging and external bulging. Silicone watchband has become synonymous with sports and fashion, not only Casio watches, such as TAG Heuer, Zhibo, etc. have also been used, and even love Peter has oh. The excellent performance determines the status of the silicone fashion watchband in the watch circle. Although the leather watchband and metal watchband are still the most popular watches for high-end watches, the silicone watchband has also steadily occupied a place. Silicone products and even watch friends have made every effort to replace the Rolex blackwater ghost metal watchband with silicone watchband, which shows the charm. There are many advantages of silicone strap, but there are also many disadvantages.

Two-color molding is mainly to use compression molding for secondary molding, to make finished products from the pattern and font on the appearance surface of silicone keys, and to fix the raw materials into the main body up and down the mold into the main body for secondary molding and vulcanization. The product process is simple and can highlight the three-dimensional feeling, but it is only suitable for two-color, three-color and other colors, and it is not convenient to make more other colors. Silica gel products have corner cracking, and the phenomenon of mold clamping and bonding splits has seriously troubled the bad sealing ring of the product. The phenomenon of product edge bursting has become the norm in the flat vulcanization process. For this reason, many silica gel gifts are prone to edge bursting under the conditions of low hardness, circular arc shape and cylindrical shape. The main reason for the explosion edge is that the product has a certain radian under the condition of low hardness of the silicone gift. Liquid silicone and a certain gap in the mold may lead to the explosion edge phenomenon of the product when the mold is closed up and down. The most common product is circular low hardness, so this is mainly due to the error in mold accuracy. The fluidity of the raw material is too poor, and the essence of the raw material is low hardness, so there are errors when adding silicone resin and vinyl silicone oil. Combined with the time temperature and pressure of the machine itself, the product burst edge phenomenon occurs. This phenomenon can be adjusted from the machine. Silicone material itself is environmentally friendly and non-toxic material. It can be arbitrarily mixed according to the color and softness you like to achieve good visual effects and feel effects. Naturally, people are indispensable. Then when it comes to the maturity of the processing technology, it fully shows that the processing patterns of many silicone gifts in our country have obtained good response effects over the years. Silicone gifts can be divided into a variety of production methods, such as high-temperature compression molding of mold silicone products, liquid injection molding, glue dropping and slicing process, appearance screen printing process and transfer appearance processing process. Silicone gift manufacturers custom processing first prepare the color of the product body, mix the raw materials, add curing agent and color glue, cut the raw materials, and carry out high-temperature vulcanization molding to achieve the molding effect.

There are also many chemical reactions, such as ozone. Ozone not only affects the aging phenomenon of silica gel, but also affects various aspects of human air. For silica gel products, ozone has a greater impact on silica gel products in the sealing ring of humid climate and environmental problems. Long-term placement in that environment will cause cracks in the direct aging of silica gel materials, while oxygen has an associated reaction with silicone rubber, it will also change the performance of silicone rubber, the use of performance decline and so on. Perhaps many friends who like online shopping know silicone products. From a macro perspective, those so-called silicone gifts, silicone accessories, silicone kitchenware, silicone miscellaneous pieces, etc. are all a small category of silicone products. In this way, the word silicone products is very large. What kind of silicone products are so popular among netizens. Silica gel is a kind of silica gel is dehydrated by the appropriate particle size of different porous material, in the silica gel products have an open porous structure, can absorb many substances, including moisture in the air and the distribution of tiny dust in the air, but also a good desiccant, adsorbent and catalyst carrier. The statement that the performance is superior, non-toxic, tasteless and resistant to high and low temperatures may be known to all as silicone products. Is the performance really so superior in all aspects? This is actually not certain. Only in terms of silicone products, more than 80% of the products have no problems and the customers have responded well. However, there are also some products with quality problems, but the occurrence of defective rate is not impossible, users will gradually age after long-term use. What are the causes of silica gel products. First of all, there are many reasons for the aging of silica gel products. Although the material performance is good, the aging time is different when applied in different fields for a long time. Some applications in high temperature places have aging phenomenon faster. For example, cracks will appear when the temperature reaches a certain height in industrial manufacturing, silicone parts will improve the oxygen diffusion effect to speed up the oxidation reaction of silicone rubber key material, which is also our common thermal effect, one of the common phenomena leading to deformation and aging of silicone rubber, so in the use of the process should be long-term maintenance of climate temperature modulation, appropriate water cooling and so on.
