Description

technical field [0001] The application belongs to the field of plastic materials, in particular to a phenolic resin wear-resistant switch. Background technique [0002] Phenolic (PhenolFormaledlyde, referred to as PF) resin is also called bakelite, also known as bakelite powder. Originally a colorless or yellowish-brown transparent substance, the market often adds coloring agents to turn it into red, yellow, black, green, brown, blue and other colors, with granules and powders. Resistant to weak acids and alkalis, and corroded in case of strong acids. Insoluble in water, soluble in acetone, alcohol and other organic solvents. It is obtained by polycondensation of phenolic aldehyde or its derivatives. [0003] Phenolic resin, solid phenolic resin is a yellow, transparent, amorphous blocky substance, reddish due to free phenol, the average specific gravity of the entity is about 1.7, easily soluble in alcohol, insoluble in water, suitable for water, weak acid, weak alkali s...
