As we all know, peristaltic pumps are widely used in a wide range of industries, and hoses are mainly used to transport general liquids and fluid mixtures. Therefore, in order to meet various work needs, a variety of peristaltic pump hoses have emerged as the times require. Let me introduce the characteristics of different peristaltic pump hose materials.
1. Silicone tube
The main chain of the hose containing silicone rubber is composed of silicon and oxygen atoms alternately, and has high-quality properties of high resistance, low resistance and oil resistance. It is one of the most commonly used pipes in the domestic biopharmaceutical industry. In order to strengthen the physical and chemical properties of silicone elastomers, there are generally two treatment methods: platinum vulcanization and peroxide vulcanization.
The first type is expensive to manufacture, but the inner wall of the tube is smooth and has good biocompatibility. It can be used as a medical grade/sanitary grade hose. The inner wall of the latter will be slightly uneven, and may react with certain chemicals and change color. In food grade technology.
2. Ordinary rubber tube
There are many kinds of rubber hoses, and hoses of different processes are suitable for different industries. Although the tolerance to organic solutions is better than that of silicone hoses, they are different for various organic substances, and their performance in other aspects is low, which is relatively cheap. the pump tube.
3. Viton tube
Fluororubber hose is a synthetic polymer elastomer containing fluorine atoms on the main chain or side chain carbon atoms, which is the best choice for transporting strong corrosive and non-polar solvents. The disadvantage is that the cost is higher, and you still have to choose different hoses according to your own needs.
