The most common problem with PVC plastic hose is that the color will fade after a period of time, and even some will fade seriously, such as PVC garden hose pipe, PVC plastic reinforced hose pipe and so on. So, how to ensure that the color of good PVC plastic hose does not fade?
Ultraviolet Ray, short for UV. UV resistance test is the “UV resistance aging test”. UV can cause equipment shell aging, exposed to outdoor equipment is usually required to do.
Aging detection is a process that simulates various factors involved in the actual use conditions of the product to carry out the corresponding condition strengthening experiment on the aging situation of the product. The experiment is mainly for plastic materials. The common aging mainly includes lighting aging, humid heat aging and hot air aging.
Products used in outdoor long-term exposure to the sun, want to know the product to be able to use in the outdoor is the life of a simulated solar ultraviolet UV aging experiment, experiment, of course, the strength of the outdoor light intensity is much larger than it actually is, so as to shorten the testing time, can pass the test for a short period of time to understand products use the change of time.
PVC plastic hose must use UV accelerated aging test machine, up to 8 cycles.
Each 12-hour cycle includes 8 hours of ultraviolet radiation (UV-A, 340mm, 60℃) and 4 hours of water test (60℃). After 144 hours of testing (1 hour is equal to the reality of 27 hours), the product can not appear rupture, and must be within the color value of 4 level, so as to be UV test qualified. And not through strict anti-UV treatment of products, fading seriously, with a period of time will break, and the surface will have the phenomenon of oil, service life is not long, will seriously affect the use of consumers.
Orientflex PVC plastic hoses are rigorously tested before they are shipped to consumers. UV resistance testing is an essential part of this process. The color of hoses are not easy to fade and the working life is longer.
