PYRITE__As fillers used in grinding wheels/ abrasive tools
Place of Origin: Henan Luoyang, China
Pyrite, Iron pyrites, pyrites lump, Ferro sulphur, Pyrites powder.
Product Description
Detailed introduction: is filling agent for ablating grinding wheel abrasive, which can effectively reduce the grinding wheel temperature during ablation, improve the heat resistance, and prolong the service life of the grinding wheel.
Formation of a protective layer
4 FeS2 + 11 O2→2 Fe2O3 + 8 SO2
400-475 degrees is a limit that the grinding wheel can easily reach. The above reaction creates an oxygen-free and hypoxic environment for the grinding wheel at the micro level, thereby improving the high-temperature performance of the grinding wheel.
FeS2→FeS + S
(4)Sulfur, sulfur dioxide and sulfur trioxide react with the workpiece surface to form FexSy:

The life of a sealed bearing is largely determined by its sealing function; the current bearing seal is a hemmed skeleton; it is usually pressed by hand; the primary drawback is: poor elastic strength; poor installation function; poor sealing function. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The bearing dust seal is a hook-shaped crimping layout; compared with the existing skills, it has the following advantages:
The sealing function is good; the sealing strength is high; the original hook-shaped curling layout of the skeleton can increase the elasticity of the sealing ring; the maximum limit compensates for the influence of the tooth size deviation; it not only depends on the elasticity of the sealing elastic body; The elasticity and strength effect; the capping rate is improved; and the machine can be pressed; it can be pressed.

Previous:Universal bearing type code indicates the following method: the effect of operating temperature on bearing life
(1)The reaction absorbing oxygen occurs between 400 and 475 degrees, thereby reducing the oxidation of resin, reducing the oxidation burn of workpieces, and prolonging the working life of grinding wheels at high temperature.
(2) 4 FeS + 7 O2→4 Fe2O3 + 4 SO2
Decomposition reaction occurs at 650-degree heat absorption, thereby reducing the working temperature of the grinding wheels.
(3) It enters the melting state at about 1100 degrees, which becomes a good lubricant to protect the grinding wheel FeS(s)→FeS(l).
