Silicone tube is a type of hose that is often used by many people, but most of the large-diameter silicon tube appears yellow during use, which is largely due to the harsh working environment. The yellowing of the silica gel indicates that the silica gel is in the process of high-speed loss and needs to be highly valued. The following is a professional silicone tube manufacturer to explain to you how to avoid large-diameter silicone tube yellowing too fast in harsh environments.
The excessive yellowing speed of large-caliber silicone tubes during product use has a lot to do with the harsh working environment. The reasons for the yellowing of large-caliber silicone tubes mostly occur in dry, non-ventilated, closed, high temperature, outdoor, direct ultraviolet radiation or Chemical reaction environment. In normal environments, the yellowing speed is relatively slow, so you can first determine whether the product is used in these environments and take targeted measures.
- In a dry, non-ventilated, closed environment, the yellowing of large-caliber silicone tubes should be improved in the storage environment and the use environment. The silica gel storage environment should be ventilated and cooled. Under conditions, the temperature drop in the warehouse can be maintained at room temperature. The warehouse environment can be properly watered to maintain humidity, or the electric fan can be cooled to keep the humidity of the silica gel relatively stable. There are also some large-caliber silicone tubes that need to be assembled in a closed environment. For sealed use, replacement of the silicone tube substrate or accessories can be solved from the source. At the same time, the addition of anti-yellowing agents during the production process can greatly reduce yellowing.
- Yellowing at high temperature outdoor: Usually this happens because the product comes in contact with the limit value of the silica gel performance. , Leading to excessive operation of silica gel, which is an important reason to accelerate the yellowing speed of silica gel. The improved method can not only control the cost, but also reduce the yellowing speed of the silica gel. To completely solve the problem of yellowing caused by high temperature, high temperature silica gel can be used instead. In addition, outdoor yellowing is due to the large-caliber silicone tube directly exposed to the sun through wind and rain, leading to accelerated physical factors. It is recommended to avoid long-term outdoor use or choose bright colors such as black and yellow to delay the yellowing rate or cover yellowing colour.
- The product is yellowed under chemical reaction or slightly corrosive environment: If the large-diameter silicone tube needs to be in contact with some slightly corrosive liquids or some chemical contacts, the silicone will also have yellowing and severe melting, which means that the silicone cannot Exposure to strong acids and bases. The improved method can adopt a new type of silica gel material (fluorine silica gel), which is used for acid and alkali (high cost), solves the problem of acid and alkali, and thus naturally solves the problem of yellowing of the silica gel.
The above is a summary for everyone in the harsh environment of the large diameter silicone tube in order to avoid yellowing in the use of the precautions, I hope to help everyone.
