Cork powder

Cork (Cork powder) purpose usually greater than 100 pieces of Cork known as cork particles, less than or equal to 100 the purpose of broken Cork known as Cork.

Its purpose: lead-acid battery grid casting, glass, lighting manufacturing mold release agents, mold insulation and ventilation in the smooth to prevent bonding. Function and mechanism in die casting alloy is formed between the insulating layer and the surface so good flowing molten alloy in die and mold in the lead does not cause deficiency of the grids in residual gas, thermal insulation box ventilation in the dual role, and lead alloys and die bonding. Grid anyway as the metal mold cooling and rib was relatively small, it is difficult to ensure liquid alloys in molten state full of mold, alloy hydraulic demoulding difficulties caused by direct exposure to mold, so longer use Cork powder suspensions as a mold release agent spraying in the mold cavity, uniformity of thickness of insulation, heat insulation, lubrication and adjustment functions. Advantages of this product uses: fine particles, distributed evenly, and the use of long cycle, flame self-extinguishing, antistatic, heat insulation. Recommend using PVA, bone glue formulations.
