The damage of PVC shower hoses may be caused by various factors, including problems with the material itself, improper operation during installation and use, as well as the impact of daily maintenance and aging. In order to extend the service life of the hose, users should pay attention to the above factors when choosing and using PVC shower hoses, and regularly maintain and inspect them.
1. Material factors
The durability and toughness of PVC pipes are closely related to the raw material ratio and process control in their production process. If the raw materials are excessively plasticized or insufficiently plasticized, the head pressure is insufficient, the low molecular weight components in the product are not discharged, the screw torque is too low, the traction speed does not match the extrusion speed, the mold design is unreasonable, the die head pressure is insufficient, the discharge from the mouth mold is uneven, and the cooling rate of the shaping mold is improper, all of which may lead to brittle failure of the pipe.
2. Installation and usage issues
Improper installation may cause the rubber ring inside the hose to deform or fall off, and the interface to be uneven or too thin, leading to damage. In addition, if the hose is frequently pulled or forms knots during use, or if the force used is too strong, it may cause the hose to break.
3. Daily maintenance and aging
PVC pipes may undergo chemical changes under specific environmental conditions, such as over plasticization or under plasticization, which can cause pipe cutting and breakage. In addition, if the pipe is not fully plasticized during the extrusion process, its mechanical properties may also be reduced, leading to brittle failure.
