Construction characteristics of refractory plastics

Refractory plastics are gas-hard or thermo-hard materials. The water content in the plastic is less, and it will harden after being exposed to the air for a short time, so the joint surface should be continuously constructed during construction. The plastic blocks must be combined with a certain ext...
