Acid resistance	In less than 20% sulfuric acid or hydrochloric acid, using less than 5% nitric acid
Alkali resistance	Can be used in 10% sodium hydroxide solution
Salt tolerance	Sodium Chloride Solution can be used at any concentration
Heat resistance	℃	≤100	GB7751–—86

2、Brief introduction of wear resistant high alumina ceramics

High alumina ceramics, also known as corundum, it is through the dry pressing molding, and then through the high temperature sintering of 1500 degrees of special wear-resistant ceramics, high hardness. With wear resistance, acid and alkali resistance, shock resistance and so on. 260 times the equivalent resistance theory of manganese steel, 170 times of chrome steel, nitrile rubber 10 times.

Main technical index：

project	Hardness of the （HRA）	compressive strength (MPa)	bulk density （g/cm³）	Alumina content(%)	Abrasion P=76N N=800r/min T=300min	Water absorption rate (%)
index	80~90	≥850	≥3.5	95~99	≤0.0009	≤0.02

3、Polyurethane elastomer

Polyurethane elastomer (PUE) is a kind of elastic polymer material, which is formed by the addition of polymer polyol and the crosslinking agent. Its characteristic is：

(1) The modulus is between plastic and rubber.

(2) Maintain high elasticity at high hardness.

(3) Wide hardness range

(4) The tensile and tear strength is 2 times more than that of the rubber.

(5) High wear resistance.

(6) Resistance to chemical resistance is good.
