What are the reasons for the poor tension of silicone mold?Mold silicone has the characteristics of high temperature resistance, good tension, many mold flip times, and many reuse times. However, in order to make silicone easier to operate, some manufacturers add a lot of silicone oil to silicone. As we all know, silicon oil will destroy the content of silicone, reduce the viscosity of silicone, make the silicone more soft and easier to operate, and cause the tension of Silicone Products Processing Factory.Solution of silicone thickening?Generally speaking, liquid silicone is placed for half a year. After more than a year, the viscosity of silicone will thicken over time. The expired liquid silicone will be condensed into a ball, which is basically not liquid, which will make us very difficult. The expired liquid silicone is very poor, and it will almost form a ball, which will cause AB to add a large amount of silicone oil, which will cause torn resistance after the silicone is cured, and the toughness will be reduced.How to increase liquid silicone without changing the characteristics of silicone?There is something on the market called expansion screws. You can buy a suitable length according to your silicone amount. After buying it, use a pliers to open the front mouth of the expansion screw jacket into a cross shape, then tighten the nut, tighten, and a simple stirred head is done.Next, stuck the stirring head on the electric diamond, began to stir crazy, and the silicone after the stirred was restored to circulation again. The newly mixed liquid silicone will be a bit hot because friction and molecular sports, and there are many bubbles. At this time, it is not wise to use it immediately. On the other hand, the heat itself will accelerate the reaction speed, or it is easy to foam, and put it. For a period of time, use it after cooling.

In the production of silicone pipes, a careless error may lead to the quality problem of the silicone tube. Such as: silicone tube yellow hard, poor aging resistance, increased flexibility, etc. The source of the Silicone Products Processing Plant tells you why the reason why the silicone tube is yellow and the matters should be paid attention to.The yellowing and hardening of the silicone tube are usually caused by aging. Controlling yellowing and sclerosis are the process of controlling aging. However, aging is divided into heat aging, ozone aging, gas corrosion aging, heavy metal oxidation aging. Reacting aging, aging of ultraviolet rays. Material aging, pH imbalance and broken chain over -sulfur can also lead to commodity aging.The question that should be paid attention to in the production of silicone pipes:1. Look at the yellow resistance of the raw material itself.2. Promoting agent system combination: The promotional agent DM and M can achieve yellow level 4 together, but the entire system needs to be re -adjusted. Using promoters is good for yellow, but it will sacrifice great toxicity and use.3. Pressing temperature control: The temperature should not exceed 150 degrees, it is best to have a significant effect below 140 degrees. Otherwise, many materials are prone to heat aging.4. Application of titanium pink powder: The application of titanium white powder is to produce mirror reflex on the surface, making it unable to pass rubber. The thinner the grain size of the titanium pink, the more thinner the dose, the better the anti -aging effect.5. Heavy metal control: If the heavy metal content is too high, heavy metals will have oxidative reactions and discoloration. The product is easy to get yellow.6. Oil application: less oil, especially the chain alkane base cannot participate in the application of ordinary rubber. Due to poor compatibility, the oil penetrates into the surface, and the additives dissolved in the oil are brought to the surface.7. PH adjustment: The glue acid value is weak, and it has a minor inhibitory effect on the vulcanization reaction, but it will control the aggravation of the broken chain.8. Application of aging agent: BHT has a good buffering effect on thermal oxygen. SP will coordinate with MB production, and the effect is also ideal. But the premise is that the quality of the material is excellent. Otherwise it will be counterproductive.In short, pay attention to the above points when producing a silicone tube in order to better prevent the silicone tubes from becoming yellow. The production of silicone pipes is an advanced technology. If you have any questions or questions, you can directly ask the Silicone Product Processing Factory Yuanxing Industry

About the silicone products processing plant, I don't know if you know the silicone products processing plant. If you do not know anything about liquid silicone products, the following silicone Lao Cui explains.As we all know, with the development and wide application of liquid silicone products, more and more liquid silicone product manufacturers began to customize according to customer requirements, choose environmental protection materials as bedding, silicone is one of them; With the market demand, silicone products have extrusion, calendering, solid, liquid processing technology and other processes, of course, each process production of silicone products in different industries have certain advantages.For example, liquid silicone products have soft rubber surface, tear resistance, high elasticity, high and low temperature resistance, yellow resistance, not easy to aging deformation product characteristics, widely used in baby toys and medical industry; Now more and more liquid silicone products also appear in our daily life, such as silicone bracelets, silicone watchbands, silicone phone cases, automotive liquid silicone accessories, liquid silicone trademarks, liquid silicone cables, medical liquid silicone products, liquid silicone seals, etc.So customized liquid silicone products, choose what kind of silicone products processing plant? Probably everyone will find a manufacturer with rich production experience, can carry out drawing sample processing, can customize the mold according to needs; For example, Shenzhen Yuanfeng Xingye, with more than 18 years of experience in the custom development of silicone products industry, professional for customers to deal with a variety of silicone products customization, development and other issues.

Silica gel is a kind of highly active adsorbent material, which belongs to amorphous substance. The adsorbent material can be made into a variety of products, such as silicone shovels. Silicone pacifier. Silicone keys. Sealing materials. Medical machinery and other supplies. When silicone is made into different products, it goes through a process. In some processes, it is not difficult to find that silicone is also prone to foaming. For the problem of silicone foam, Silicone product processing plant  tells you that you can use silicone foam agent to solve.The sources of silicone foam are as follows:1. The raw materials in silicone are easy to bubble, leading to foaming in the production mixing process.2. In the process of processing, other additives will be added, which contain surfactant or react with silicone material, causing bubbles.3. Silicone after some high temperature process, high temperature causes local substance foaming.The adverse effects of silicone foam are:1. Silicone foam will affect the appearance and image of the final product, leading to adverse problems.2. Silicone foam is easy to increase unqualified products and increase production costs.3. Silicone foam will affect some processes and production efficiency.In view of the adverse effects of silicone foam, we can use silicone defoamer to help solve the problem. The effects of silicone defoamer are as follows:1. Silicone defoamer can remove the foam in the process of silicone processing, without affecting the performance of silicone products themselves, specially developed for silicone defoamer.2. Silica gel defoamer has stable characteristics and can maintain stable defoamer and defoamer inhibition ability at high temperature.3. Silicone defoaming agent for the problem of silicone foam, add less, can achieve good defoaming effect.
