If the shower hose is improperly selected, it will not only affect the service life, but also affect the health. The consequences of improper selection of shower hose are very serious.
The inner tube material of the hose directly affects the service life. At present, the common inner tube materials on the market are:
1. PVC is generally transparent in color, and its applicable water temperature range is between - 15 and 55 degrees. The advantage of this material is that it is cheap, but its service life is relatively short, especially
The light and thermal stability is relatively poor, and it is easy to cause discoloration under high temperature environment, and high temperature will also lead to rapid decline in its physical and mechanical properties.
2. EPDM, this material has strong ozone resistance and ultraviolet resistance, and its temperature resistance range is wide. It can be used in the temperature range of - 50 ℃~+150 ℃, and its service life is long.
3. Regenerated rubber is generally processed with waste materials such as outer tubes and inner tubes as raw materials. If this material is used for a long time, it will have a great impact on human health.
In general, we recommend that you choose the hose of EPDM inner tube as much as possible. Although the hose is more expensive, it has a long service life. Therefore, in general, the cost performance ratio is relatively high.
At present, it can also be seen that the inner tube of some hoses uses waste rubber, which not only looks rough, but also has a thin inner tube. Even if the outer tube is electroplated, it can be seen that there are obvious scratches on the surface. When you weigh it by hand, you can find that the weight is very light. This kind of hose is very cheap. Some manufacturers even sell it by weight. We recommend that you try not to choose this kind of hose.
