Why does the peristaltic pump silicone hose change color at high temperature and its solution

Micro peristaltic pump is a commonly used industrial pump, widely used in fields such as chemical, pharmaceutical, and food processing. Under certain conditions, discoloration of the silicone tube may occur when using a peristaltic pump. This article will delve into the reasons for the discoloration of peristaltic pump silicone tubing at high temperatures and provide some solutions.

We need to understand the characteristics of silicone tubing. Silicone hose is a type of rubber product with excellent high-temperature resistance and good chemical resistance. However, at high temperatures, the silicone tube still undergoes some changes. One possible reason is that the silicone tube material undergoes thermal decomposition at high temperatures. High temperature can cause changes in the molecular structure inside the silicone tube, leading to color changes. In addition, when exposed to high temperatures, silicone tubes may react with chemicals, further exacerbating the discoloration phenomenon.

So, why is the peristaltic pump silicone hose prone to discoloration at high temperatures?

High temperature will accelerate the aging process of silicone tube materials. Long term exposure of molecules inside silicone tubes to high-temperature environments can lead to structural damage and deformation. These changes may change the color of the silicone tube, and over time, the discoloration phenomenon will become increasingly apparent.

Secondly, there may be some chemical substances that react with silicone tubes in high-temperature environments, leading to discoloration. In some industrial production processes, high-temperature chemicals may be used, and when these substances come into contact with silicone tubes, chemical reactions may occur, leading to discoloration of the silicone tubes. In this case, the discoloration phenomenon may be caused by the attachment of substances generated by chemical reactions to the surface of the silicone tube.

In addition, the operating conditions of the peristaltic pump can also affect the discoloration of the silicone tube. For example, during the operation of a peristaltic pump, if the liquid temperature is too high or there are some harmful substances in the liquid, it may cause discoloration of the silicone tube. At the same time, factors such as the operating status of the peristaltic pump, the design and operation of the pump head, may also have a certain impact on the discoloration of the silicone tube.

We can take some solutions to address the issue of discoloration of peristaltic pump silicone tubing at high temperatures, in order to extend the service life of the silicone tubing and reduce the occurrence of discoloration.

We can choose silicone tube materials with better high-temperature resistance. There are many different types of silicone tubes on the market, each with different heat resistance properties. When purchasing silicone hoses, we can choose suitable high-temperature resistant silicone hoses based on the temperature requirements of the specific working environment to reduce the possibility of discoloration of the silicone hoses.

Secondly, we should regularly inspect and maintain the operating status of the peristaltic pump. Maintaining the normal working state of the peristaltic pump can reduce the chance of damage to the silicone hose and extend its service life. Regularly inspect the pump head, pipeline connections, and other parts, repair or replace problematic components in a timely manner to reduce the risk of discoloration of silicone tubing.

It can also optimize the working conditions of the peristaltic pump. For example, controlling the temperature of the liquid to avoid exceeding the heat-resistant temperature range of the silicone tube; Use harmless chemicals to avoid discoloration caused by chemical reactions. In the operation and maintenance process of peristaltic pumps, we should pay attention to details, maintain stable operation of the pump, and comply with relevant operating procedures.

In summary, the reasons for the discoloration of peristaltic pump silicone tubing at high temperatures are multifaceted, including the characteristics of the silicone tubing material itself, chemical reactions in high-temperature environments, and working conditions. To reduce the occurrence of discoloration of silicone tubing, we can choose suitable silicone tubing materials, regularly inspect and maintain peristaltic pumps, and optimize working conditions. Only by comprehensively considering these factors and taking corresponding measures can the service life of silicone hoses be effectively extended and the occurrence of discoloration problems be reduced.
