Why PVC plastic reinforcement spiral reinforced hose is easy to break in winterWhy PVC plastic reinforcement spiral reinforced hose is easy to break in winter
PVC plastic reinforced hose is widely used in industrial life. It is used in the drainage field of highways, railway subgrades, tunnels, green belts, abandoned fields and other places, and it is also essential in agricultural irrigation. The PVC plastic rib spiral reinforced hose is a spiral hose formed by winding a soft PVC pipe wall with a hard skeleton. Customers often respond that the purchased PVC plastic hoses are easy to break, especially in winter, the hoses will become brittle, and they will break when bent slightly. What are the reasons that cause the PVC plastic reinforcement spiral reinforced hoses to become brittle and break in winter?
1. Material problem of PVC plastic reinforced hose
As we all know, no matter which kind of product the raw material has, there are advantages and disadvantages. Some low-priced PVC raw materials often add a lot of additives. The more additives are added in terms of toughness, the easier the produced hose is to break. Especially for the hard skeleton, poor raw materials do not have to wait until winter, and are easily broken at normal temperature. For some occasions that require cold resistance and low temperature resistance, there will also be some PVC raw materials for high cold resistance. This special raw material is more cold resistant than ordinary raw materials, and it is not easy to break in winter.

Second, the production process of PVC plastic hose
PVC plastic hose is produced by co-extrusion of two extruders. The temperature control during extrusion is very strict. It is also a PVC plastic reinforced hose, which can not be seen in appearance, but it is a little stepped on with the foot It broke with a click, and some of them just stepped back and immediately rebounded. Why is it broken? This is also related to the extrusion temperature control. In short, the production process causes the skeleton to become brittle.
Third, the storage problem of PVC plastic hose
Most PVC hoses are not UV-resistant (except for special customized UV-resistant products), so when storing, the hose should be placed in a place where it can not be exposed to the sun, it is best to be completely closed and no light In the warehouse, if it is exposed to ultraviolet rays, it will cause the aging of the hose to accelerate, which makes the PVC plastic hose easy to break.
