The main component of PVC fluid hose is polyvinyl chloride. Its color is bright, corrosion resistant and durable. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents during the manufacturing process, it can enhance its heat resistance, toughness and ductility, so its products do not normally store food and medicine.
How to distinguish the quality of PVC hose?
1. Look at whiteness and gloss. If too much miscellaneous materials and recycled materials are added in the production process of PVC hose, the pipe will turn black and yellow, affecting the quality of PVC hose.
2. Observe the thickness. Check whether the wall thickness of PVC hose is uniform according to the pipe diameter rules.
3. Take the sample and throw it. If you have high requirements for product quality, you can wrestle the PVC hose to check its toughness. The PVC hose that is easy to break is generally a high calcium product.
4. Weather resistance. The most direct way is to take the PVC hose to a place with high temperature and high light for a few days and observe the surface change rate. The smaller the surface change, the stronger the weather resistance of the PVC pipe.
5. Look at the material. Analysis of PVC hose materials requires professional knowledge and equipment, but some simple judgment methods are also effective. Compare the weight of two pipes with the same diameter, wall thickness and length. If the weight of PVC hose is high, there are too many calcium powder and impurities, and the material is impure, which can not meet the requirements.
Key points: for PVC hoses produced by regular manufacturers, there is a relatively perfect testing process in the production process, and the quality is more guaranteed.
