What if the poly/cotton woven sleeve is damaged from the edge and center?

The damage to polyester/cotton sleeves is generally divided into two situations, one is that the strength of the material is very high, and the friction caused by the polyester/cotton sleeves is relatively large, resulting in damage to the polyester/cotton sleeves, and the other is not mending and polyester The friction in the middle of the polyester/cotton sleeve will make the polyester/cotton sleeve produce thousands of small holes, causing the polyester/cotton sleeve to be damaged from the edge and center.

1. The mesh size of the Polyester/Cotton Braided Sleeve is determined by the diameter and the pitch. At this moment, we need to clarify that the diameter will not change to increase the pitch, and the other is to use high-strength polyester/cotton. Cotton braided sleeves, so that the polyester/cotton braided sleeves are not easy to wear the screen in a short period of time.
2. For a while, it will happen in the process of filtering high-precision viscous slurry. It is common for everyone to see that the Polyester/cotton Braided Sleeve is often damaged from the edge and the middle during the process of sieving porcelain slurry. Since the polyester/cotton woven sleeves used for filtering porcelain slurry have a high mesh number and are too expensive, saving polyester/cotton woven sleeves means saving product costs.
We lift the edge of the screen frame like a leather pad, so that the friction of the polyester/cotton woven sleeve on the edge becomes soft friction, and the center of the general polyester/cotton woven sleeve has a large bearing capacity, in other words, the polyester/cotton woven sleeve in the center The friction between the sleeve and the lining net is serious, and the sieving effect of this piece is just poor, so we also separate the 5cm in the center of the polyester/cotton sleeve with an eraser pad. In this way, the forced friction between the polyester/Cotton Braided Sleeve and the lining mesh and the edge of the polyester/cotton Braided Sleeve is reduced. Experiments have proved that the service life of the polyester/cotton braided sleeve can be increased by 3 to 5 times as long as before.
The corrosion resistance of stainless steel polyester/cotton braided sleeves depends on the chromium composition. When the chromium content reaches 10.5%, the air corrosion resistance of the steel can be significantly improved, but when the chromium content is higher, the corrosion resistance can still be improved. corrosion, but not significantly. The reason is that when chromium is used for solid solution strengthening of steel, the type of surface oxide is changed to a surface oxide similar to that formed on pure chromium metal. This tightly adhered chromium-rich metal oxide protects the surface from further atmospheric oxidation. This kind of oxide layer is thin, through which the natural gloss of the stainless steel surface can be seen, so that the stainless steel has a surface. Moreover, if the surface is damaged, the exposed steel surface will react with the air to repair itself, forming this "passive film" again, and continuing to play a protective role.
