Cause Analysis of Hose Corrosion
Author:
Hose is one of the tools we often see and use in our lives. Basically, every household will use it. In the kitchen and bathroom, it hides in the corner we can't see.
Hose Features
1. Flexible between pitches.
2, have good flexibility, no blocking and stiffness.
3, light weight, good caliber consistency.
4, soft, repeated bending, good flexibility.
5. Good corrosion resistance and high temperature resistance.
6, anti-mouse bite, good wear resistance, to prevent the internal wire from being worn.
7. Bending resistance, tensile performance and strong lateral pressure resistance.
8. Soft and smooth, easy to thread installation and positioning.
Hose composition analysis
Hose (plastic corrugated pipe, imported hose) can be used in solid wall or structural wall design, the connection is mainly solvent bonding. According to whether plasticizer is used, it can be divided into hard polyvinyl chloride (the corrosion resistance and high temperature resistance are relatively high, and the cost is relatively high.
PVC hoses (sanitary plastic hoses, plastic hoses, plastic corrugated pipes, food-grade hoses, sanitary hoses, imported hoses) have been widely used in water supply pipeline systems and gas delivery pipeline systems, but in recent years PVC The market share of the pipeline system in the field of gas transmission is almost zero, and the amount of water supply system has also declined slightly. However, the use of PVC hoses in pressureless piping systems such as drainage, sewage and waste systems has grown steadily, mainly because the production of PVC raw materials is not as dependent on crude oil as other thermoplastics, making its production costs Relatively low.
PP hose (sanitary plastic hose, plastic hose, polypropylene hose, food grade hose, sanitary hose, imported hose) has been used in the production of pipes since the 1970 s. According to the different polymer structure, PP material can be divided into PP-H (homopolymer polypropylene), silicone hose PP-B (block copolymer polypropylene) and PP-R (random copolymer polypropylene) three categories.
