Different Kinds Of Hydraulic Hose
Some PVC hose manufacturers reflect that their hose in the customer use did not appear a problem, but in their own testing found that the pipe in the bending degree is relatively large (such as 180 degrees), in the open air environment in the sun for a week, there will be a lot of cracks, like aging. And some other manufacturers, in the glue content is relatively low, this crack is not too obvious. What is the reason for this? Today, let’s learn more about why PVC steel wire spring hose crack with Orientflex, a PVC hose manufacturer.
1. It is easy to crack after bending, which may be caused by poor ozone performance and low glue content. It can be improved from the adjustment of formula.
2. If the glue content is relatively low and it is not easy to crack, it depends on the filler, the choice of raw glue type, and the improvement of the protection system may be improved.
3. The hose bent 180 degrees after exposed to the sun for seven days, it will crack. There may also be little relationship with the rate of rubber hose. More likely: after bending, stress concentration, accelerated aging hose. Insolate for seven days, the ultraviolet ray in the sun has a effect on the hose, is aged by ozone, cracking.
The above is the cause of PVC steel wire spring hose crack in the production process. Orientflex is made of 100% high-quality PVC raw materials and the production process is transparent and visual. Welcome customers to visit the factory.
