Application of green carborundum GC in sandblasting, grinding and polishing phenolic plastics
Green carborundum GC has the following core functions in sandblasting, grinding and polishing of phenolic plastics:
1. Surface treatment optimization
Efficient removal of impurities
Green carborundum GC, with its physical properties of Mohs hardness of 9.4, can quickly remove burrs, residues and oxide layers on the surface of phenolic plastics without damaging the substrate.
Enhancing coating adhesion
The uniform rough surface structure formed by green silicon carbide after sandblasting significantly improves the adhesion between phenolic plastics and subsequent coatings (such as anti-corrosion layers), extending the service life of composite materials.
2. Improved processing performance
Precise grinding control
Green carborundum GC (240#-10000# micro powder) with uniform particle size distribution can achieve high-precision grinding, which is particularly suitable for fine structure finishing of thermosetting materials such as phenolic plastics.
Polishing finish improvement
Green carborundum GC as a coated abrasive material (such as abrasive belts and sandpaper) can make the surface of phenolic plastics reach Ra≤0.1μm mirror effect during the polishing process, meeting the needs of precision electronic component packaging and other scenarios.
3. Process adaptation characteristics Thermal stability support
Green carborundum GC can withstand the processing temperature range of 200-300℃, adapt to the instantaneous high temperature that may be generated during the processing of phenolic plastics, and avoid deformation of the material due to thermal stress15.
Media compatibility advantage
Green carborundum GC has good compatibility with phenolic resin matrix and cutting fluids such as polyethylene glycol, and can maintain stable suspension and dispersibility in wet polishing processes.
4. Comprehensive benefits Extended tool life
When green carborundum GC is used as a filler for resin grinding wheels, its wear resistance can increase the life of the grinding wheel by 30%-50%, reducing the overall cost of phenolic plastic processing.
Environmentally friendly process adaptation
Green carborundum GC is a RoHS-compliant green carborundum GC abrasive that is irreplaceable in the environmentally friendly surface treatment of phenolic plastic products.
Note: In actual applications, it is necessary to select an adaptive size within the range of JIS#240-#10000 according to the filler type of phenolic plastic (such as wood powder, minerals, etc.) and the hardness of the product.
