What is the reason for the tearing of silicone products?

2021-03-13 09:06:58

Many friends know that a beloved accessory is broken and dirty but they don't know what to do. They think that the sealing ring can continue to be used, but when it is too dirty, they don't want to continue to use it. Many of our friends often have this kind of situation in silicone products. A beloved silicone accessory, a fashionable and exquisite silicone phone case, etc., are dirty but they don't know what to do. When cleaning, you can use detergent, toothpaste, balm essence, white electric oil, alcohol and so on. Of course, the functions of various cleaning agents are also different. Generally, we don't have some special tools in our life. We can use detergent, washing powder and tooth liquid silicone paste to clean. Soak the silicone jewelry in clear water for about ten minutes, wring it out with a wet cloth and wipe it inside and outside, toothbrushes can also be used to clean places where dirt cannot be wiped, and then blow them to a certain dryness with a hair dryer. Don't blow them too dry or too wet. If you blow them frequently, cracks will easily occur if they are too dry. If you don't blow them dry, discoloration will easily occur if you leave them in a humid place for too long. Don't expose them to the sun after blowing, which is also easy to discoloration or deformation, the pulling force is not enough. As we all know, there are many factors that cause plastic products to tear and break down. Apart from human phenomena, different problems will occur in their respective working environments. Therefore, this also leads to one of the reasons why many consumer friends do not like to use silicone products. For example, we commonly use silicone mobile phone cases, which may be easily marked when we encounter sharp things inadvertently, and this is also one of the important reasons for consumers to worry, can not touch sharp tools, can not pull too much force and other phenomena, but silicone products any product has no complete advantage, have their own advantages and disadvantages, just see how you use and maintenance correctly, that for tearing phenomenon, you do to prevent it. When it comes to tearing phenomenon, we have to start from the production source of silicone product manufacturers. There are many reasons for tearing phenomenon in manufacturers. For example, the reasons of raw materials may lead to two effects. Selecting common materials and high tensile materials on raw materials will lead to two effects. Therefore, the quality of silicone products will vary with different materials and different quality and tear resistance, of course, if there is not enough experience to control vulcanization in the production process, it will naturally be of no help. Therefore, time control is very important in the molding production process. If the vulcanization time of the product is too long, the tea grower may be too brittle and inadvertently torn. In addition, if the trimming is not properly trimmed, the product may be easily torn in subsequent use.

If how to improve the production efficiency of silicone products

2021-03-09 10:22:11

Change the discharging method of silica gel raw materials, and try to make the silica gel raw materials fill the whole mold cavity gradually from the side wall of the mold cavity to the sealing ring during the pressurization process. The silica gel raw materials of silica gel products can be divided into ordinary silica gel and meteorological silica gel according to their performance. Change the exhaust frequency and exhaust stroke, which requires higher working experience of the conditioner, because according to common sense, the larger the exhaust stroke of liquid silica gel, the more exhaust times, will be more conducive to exhaust, but this is not the case, need to be determined according to the structure of the product, some silicone products exhaust stroke will appear bad bubbles, and small to solve, silicone products factory. Identify the actual material of silicone products in the following ways:. 1. Ignition method, extraction of test articles, burning in gas, observing and checking the condition, naturally, if through observation, ignition, color tone and taste, people will also be shown more information content for silicone key manufacturers, such as NBR/PVC and glue. When there is an open flame, the fire splashes randomly, like water, the fire is self-contained, the smoke is thick and has peculiar smell, it must be noted that sometimes the glue with halogen-free flame retardant but no seal halogen will also self-extinguish, which depends on other methods to further deduce. 2. Ultra-low temperature method, extract the test article, produce a suitable ultra-low temperature natural environment with dry ice and ethanol, soak the test article in the natural environment of ultra-low temperature rubber products for 2-5 minutes, and feel the hardness and softness level of the O-ring at the selected temperature, for example, at -40 ℃, the silica gel and fluorine rubber with good heat resistance, acid and alkali resistance will be softer. 3, measuring the proportion, rubber keys with high-precision electronic scales, plus a cup of water, a hair can be, generally speaking, fluorine rubber proportion is larger, about 1.8, CR,ECO is also more than 1.3, the proportion is significantly larger can consider this kind of glue. Nowadays, due to the characteristics of silica gel itself, it can be used in many fields, and it is worth mentioning that it is environmentally friendly. In this way, it can be used in life, but in actual production, silica gel products will always be affected by multiple factors. It is necessary to understand some improvement methods. Appropriately increase the amount of vulcanizing agent added in silica gel raw materials, or select rapid vulcanizing agent, so as to speed up the vulcanization molding of silica gel products. The structure of the product determines that as long as the silica gel keys of silica gel products are not deformed and numb, if it is silica gel keys, pay attention to whether the load will be high.

What is the appropriate hardness control of silicone O-ring

In order to make the appearance neat and beautiful, it must be removed. This process is called trimming, O-ring seal insulation silicone pad, excellent high temperature resistance, silicone (edible liquid silicone grade silicone) can withstand high temperature of 200 ℃ and can be used for a long time. The raw materials produced by this product meet SGS standards, pass FDA food grade silicone testing standards, are tasteless and non-toxic, and the manufacturer produces according to the mold. The color and shape can be customized by the silicone product factory, the requirements for trimming are accurate dimensions and neat appearance. Friends who often contact silicone products will find that some silicone products feel soft and some silicone products are hard. This is the hardness of silicone key products often mentioned by silicone manufacturers. Silicon pixel products have different requirements on the hardness of rubber and plastic products in different occasions and different use environments. For example, silicone breast augmentation prosthesis has lower hardness in order to achieve the real feeling with the chest. Needle seals choose silicone products with different hardness for use in different fields. The regular low hardness can reach about 10 degrees, or even lower than 3-5 degrees. The regular hardness of silicone products usually used is between 30 and 70 degrees. Rubber products are also the reference hardness of most products, but the hardness of silicone products with special materials can reach about 80-95 degrees. Another is the common silica gel processing technology, that is, the processing technology of solid silica gel products. At present, the processing technology of solid silica gel products in the whole silica gel industry can achieve a lower softness of 10 degrees and a higher hardness of 90 degrees. Although higher can be achieved, the defect rate is too high, the product is brittle, the cost is high, and it is not easy to demold. The choice of rubber O-ring hardness is more important, such as a power station pump turbine hardness of 70 sealing ring, often peeling, or even transverse cut (cut, cut), after the use of 85~90 sealing ring, the effect of silicone products want. Unvulcanized rubber O-ring rubber material is viscous fluid under high temperature and pressure. At the stage of molding and vulcanization, the rubber material quickly fills the mold cavity. The surplus part (in order to prevent rubber shortage, the rubber material filled in the mold cavity and the silicone key must maintain a certain excess) overflows vulcanization, forming overflowing rubber (also known as waste edge and flash). Silicone sealing ring is mainly used for fresh-keeping boxes, electric rice cookers, water cookers, water dispensers, drinking water dispensers and lunch boxes, waterproof sealing and preservation of daily necessities such as heat preservation boxes, heat preservation boxes, water cups, ovens, magnetic sealing rings, coffee pots, etc.

How high temperature can silicone products withstand?

For the silicon industry, the upstream is pure in industrial flavor, while the downstream is pure in quality and environmental protection flavor. The upstream is more stable than the products and has a high quality matching degree, while the downstream is relatively compared with the quality, appearance, factory degree and purity of fine silicone products, so the relative difference is not big. Perhaps the test reports provided by our country are not as fine as those provided by foreign enterprises. Silicone materials have excellent heat resistance, cold resistance, dielectric properties, ozone resistance and atmospheric environment aging resistance. Silicone rubber can be used for a long time at -60 ℃ (or lower temperature) to 300 ℃ (or higher temperature). Silicone can withstand high temperatures between 200 and 300 ℃. Its characteristics are as follows: insulation, heat dissipation, temperature resistance, flame retardant and environmental protection of seals, anti-skid, insulation, temperature resistance and wear resistance, anti-aging, compression resistance and other characteristics. High temperature resistant silica gel is generally divided into high temperature resistant solid silica gel and high temperature resistant liquid silica gel, so the liquid silica gel should be kept in a liquid state, so the number of heat resistant fillers allowed to be filled with rubber products is less than that of solid silica gel. Therefore, in general, solid silica gel is more heat resistant and easier to realize. Special high temperature resistant silica gel can pass through 350 degrees. The high temperature resistant silica gel is mainly made of phenyl silicone rubber and gas phase white carbon rubber key black as raw materials, supplemented by high temperature resistant additives, so that the high temperature resistant capacity of the product can reach 300-350 ℃, without secondary vulcanization. It has high tear resistance, good resilience, not easy to yellow and good hand feeling. I believe many friends will have different choices. In fact, this is not aimed at anything, but there is a certain gap between the raw materials provided by the upstream suppliers of wholesale silicone rubber products and those provided by foreign countries. For example, many silicone rubber products manufacturers downstream of silicone rubber products now choose different raw materials, resulting in different contrast in various properties of the products or the quality is not stable enough, such as some silicone products that need good performance, the main reason for the failure may also be due to raw materials, and it is precisely for this reason that many manufacturers refuse to use domestic brands. The difference between the raw materials, whether it is precision silicone products, or commonly used silicone accessories, there are certain differences from all aspects, such as the weight of the seal ring will get different comfort, imported materials are more abundant, toughness and resilience better, and the color composition of raw materials also have certain differences, so it is not to say that the quality of foreign countries is good, instead, customers and consumers get stronger performance and stability of liquid silicone products.

At present, there are many kinds of silicone products, the most prominent ones are: silicone keys, silicone rubber seals, silicone phone shells, silicone products factory children's tooth glue and baby pacifier tooth glue, kitchen silicone tableware and silicone gift accessories, etc. With the development of industry to the 4.0 era, manufacturing industry has become the main core driving force of intelligent R & D and production, the silicone upstream and downstream combined with electronic information world silicone key manufacturers will bring silicone into our daily necessities, one of the main materials, mainly used for some electronic products combined with silicone rubber to lead the introduction into the market, recognized by consumers. Different processes and different ways of processing seals are required to meet product requirements:. In addition to the main silica gel, some consumers also require the appearance and functionality of silica gel products to achieve the expected effect, so there are certain requirements for external processes, such as sewing rubber products, transfer printing, coating and so on. The production and processing of this kind of products requires more powerful manufacturers, familiar with all aspects of technology and processing flow, otherwise some suppliers found will not achieve the expected goals. Rubber keys. For the first time, there is not much understanding of silicone products, resulting in the quality and functionality of the products did not reach the expected effect, this phenomenon requires analysis of the industry standards of silicone products and the production process of silicone manufacturers and mold precision. With the improvement of human living standards, the research and development of different new products are constantly in front of our eyes, of which electronic products are the most prominent. From the pagers in the 1980 s to the present, smart phones have some AI electronic devices. Besides electronic silicone products, there are also certain changes in other products. Among them, silicone products belong to only one category. At present, "silicone" is proudly reused in many industry fields, what is more prominent is that it is in the same category as the silicone button of the living family. Do you know what advantages and functions it has. Silicone material belongs to one of rubber and plastic materials. Theoretically, it also belongs to rubber and belongs to a synthetic silicone rubber material. The main sealing ring components are white carbon black, silicone resin and dimethyl siloxane are raw rubber, which can only be completed after being mixed with reinforcing filler and vulcanizing agent for curing. It belongs to soft solid rubber like rubber, but it is better than rubber material in performance, safety and environment-friendly liquid silicone, so it is widely used in silicone household products.
