FAQ
Q1: What is the main function of pyrite in precision hardware manufacturing?
A1: It acts as bonding reinforcing filler, friction stabilizer and extreme pressure lubricant. It improves high temperature resistance, wear resistance and mute effect for grinding wheels and brake pads, and enhances anti-wear performance of industrial lubricants.
Q2: What mesh size is suitable for different usage?
A2: 80–200 mesh for resin grinding wheel and brake pad batch mixing; 325 mesh general grade for conventional formula; 325–1000 mesh ultra-fine for high-end lubricant and precision friction parts.
Q3: Will pyrite affect the strength and service life of abrasive and brake products?
A3: No. With stable sulfur content and controlled impurities, it optimizes internal structure of resin formula, promotes bonding tightness, extends service life and maintains stable friction feeling in long-term use.
