Abrasion resistant material

1、Introduction of TG-NM Wear-resistant Material

TG-NM wear-resistant material is a two-component reactive material made of toughened wear-resistant resin and brown corundum etc. It is widely used in the fields of cyclone, conveyor pump worm shell, flotation machine trough bottom, pipe elbow etc. It is especially suitable for repairing of shaped parts.

Main technical indexes:

Items unit Standard value Detection methods
shear strength MPa ≥15 GB7124—86
tensile strength MPa ≥30 GB6329—86
compressive strength MPa ≥100 GB177—85
wear value mm3/h 0.02~0.035  
acid resistance Can be used in ≤20% sulfuric or hydrochloric acid, ≤5% nitric acid solution
alkali resistance Can be used in ≤10% sodium hydroxide solution
salinity Can be used in any concentration of sodium chloride solution
heat resistance ℃ ≤100 GB7751–—86

2、Wear-resistant high alumina ceramics

High-alumina ceramics, also known as corundum, are special wear-resistant ceramics with extremely high hardness, which are dry-pressed by abrasive tools and then sintered at a high temperature of 1500°C. They are also known as corundum. It has the characteristics of wear resistance, acid and alkali resistance, impact resistance and so on. Theoretical wear resistance is equivalent to 260 times of manganese steel, 170 times of chromium steel and more than 10 times of nitrile rubber.

Main technical indicators:

Items Rockwell hardness （HRA） compressive strength (MPa) bulk density （g/cm3） Aluminium oxide content(%) wearing out by friction P=76N N=800r/min T=300min water absorption< (%)
norm 80~90 ≥850 ≥3.5 95~99 ≤0.0009 ≤0.02

3、Reaction Sintered Silicon Carbide

Silicon carbide ceramics have the advantages of high temperature resistance, corrosion resistance, ultra-high hardness and abrasion resistance, oxidation resistance, high strength, etc. They are mainly used in the production of cyclone wearing parts.

4、Highly abrasion-resistant polyurethane

Through molecular grafting modification, Tongge has made the DIN abrasion value of high wear-resistant polyurethane materials reach 85, and its service life is 1.5-2 times longer than that of general-purpose polyurethane in field application tests.

5、Highly abrasion-resistant rubber

Selection of specially formulated process of lining rubber layer, wear-resistant, acid-resistant performance is good.
