What are the advantages of our spiral protector？
Today, the editor will take you to know our high-quality spiral protective sleeve.
1、 Good wear resistance. Whether the spiral protective sleeve is wear-resistant depends on the material rather than the thickness. The spiral protective sleeve produced by parlmu company adopts modified PP raw material, which is an ideal wear-resistant material. We have modern production equipment and advanced testing instruments, which are made by retail winding qualitative extrusion process. The production of the assembly line makes the quality of the protective sleeve more stable and the data more accurate. Under the surface pressure of 1.9mpa, (disc pin friction tester) continues to grind for 1000km or 415h, with only 0.5mm wear.
2、 Good oil resistance. The oil resistance of the spiral protective sleeve is obtained through testing. Test method: immerse the spiral protective sleeve in the mixture of 70# gasoline and 10% toluene for 5 minutes. If there is no discoloration and stickiness, it is qualified; Otherwise, it is unqualified. After strict testing, the spiral protective sleeve of Qinghe Great Wall has no discoloration and adhesion.
3、 Good high and low temperature resistance. The spiral protective sleeve has high and low temperature resistance: 1 hour at 80 ℃, 0.5 hours at room temperature, - 40 ℃ for 1 hour and 0.5 hours at room temperature. It is a cycle and five consecutive cycles. It is observed that if the spiral protective sleeve has no cracking, sticking, depression and other phenomena, it is of high quality; Otherwise, it is inferior and unqualified. After testing, our sample has no cracking, deformation, sticking, depression and other phenomena.
Zuo Youzhong workers conduct sampling inspection for each batch of spiral protective sleeves before, during and after production to ensure that the factory pass rate is as high as 99.00%. We solemnly promise: one year warranty, seven days no reason to return.
