Misunderstandings on bearing quality discrimination
CPVC Resin made by polyvinyl chloride( PVC) resin chlorinated modified system. Appearance is white or light yellow, tasteless, non-toxic loose grain or powder.
Characters:
I. Widely used range---Vicat Softening Point than PVC increases by 40℃, one of polymer can be used in high temperature and high pressure for long time;
II. Mechanics performance---tensile strength than PVC increases by 50%, 1 time increases than ABS resin, PP resin, CPVC could still maintain in a strong rigidity, fully meet at this temperature to the requirements of the equipment and pipeline especially close to 100℃;
III. Chemical corrosion resistance---CPVC not only has chemical corrosion resistance in room temperature, but also has good acid and alkali resistance at higher temperature, far better than PVC and other resin, it can replace the traditional material to handle corrosive substance;
IV. Good fire-resistance---CPVC with good self-extinguishing feature, the limiting oxygen index is 60, no form drop, limit flame spread and smoke generation;
V. Low co-efficient of heat conductivity---the heat conductivity of CPVC is 0.105KW/(mk), the CPVC heat-resisting pipes are with less heat loss and the heat insulating layer is unnecessary;
VI. The CPVC will not be affected by the chlorine left in water--Polyolefin Material( such as PP/PE) will decompose when they meet the chlorine left in the water, will not have crack or drip;
VII. The bacteria will not easy to breed---because the CPVC pipe will not be affected by the chlorine left in water, and also can resist the common sterilization chemicals;
VIII. It's same with PVC when processing---the processing way of CPVC finished products is same with PVC product, it's very easy and convenient.

1. Feeling the quality of the bearing through the appearance. In the process of selling the bearing, I found that many customers said that only the external light of the bearing is good quality; this is wrong. The brightness of the bearing should be black and bright; the reason for this black light is Whether the steel used in the bearing can be qualified and its grinding process and the cutting fluid used, etc.; /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
2, chamfering whether the chamfer of the bright bearing does not determine the quality of the bearing; but it reflects the processing method of the bearing. The chamfer is black; clarify the heat treatment by quenching, etc.; thus adding the hardness of the bearing; and some people think that the chamfer is Black is not good looking is not processed completely; this is a misunderstanding.
3, one cage is better than the two; although the new process uses an integrated cage; but it only saves data; and the performance of the reverse is worse than the two.
In general; the service life of the bearing is related to three elements; one is the quality of the bearing itself. The second is the use of the environment. The third is the installation method.

Several common methods to distinguish the bearing quality. What is the frequent damage of the universal joint bearing?
