Checking the quality of PVC water belt can be started from the following aspects

Checking the quality of PVC water belt can be started from the following aspects:

Appearance check

- Color: good quality PVC water belt color uniformity, with a natural luster. If the color is gray, uneven, may be poor material or production process problems.

- Surface: touch the surface of the water belt with your hand, it should be smooth and flat, without cracks, bubbles, sand holes and other obvious defects. These imperfections may cause the water belt to leak during use.

Material check

- Flexibility: gently bend the water belt, good quality PVC water belt flexibility, can be naturally bent and will not appear white, broken phenomenon. This indicates that the material has good elasticity, in the process of use can be better adapted to different laying environments.

- Thickness uniformity: check whether its thickness is uniform along the length and circumference of the water belt. It can be judged by measuring the thickness at different positions. Uneven thickness may affect the pressure resistance and service life of the water belt.

Performance check

- Pressure resistance test: If the conditions allow, you can inject the right amount of water into the water belt to make it withstand a certain pressure (pay attention not to exceed the pressure resistance range of the water belt label), observe for a period of time, check whether there is leakage, bulging phenomenon. This is the most direct way to check the quality of water belt.

- Connection firmness: check the connection part of the two ends of the water belt, good quality water belt connection firm, fine workmanship at the interface, there will be no loosening, falling off the situation. You can try to gently pull the interface to see if it is solid!
