What Is The Seal Plate

The seal plate is an important consideration - liquid strippers are easy to drain. Paste strippers can stick to the surface, but it should be noted that there is no correlation between the viscosity and the strength of the stripper. Sealing plate 4 kinds of strength stripping agent, whether liquid or paste in which the dichloromethane solvent volatilization rate is very fast, so it is usually necessary to add paraffin to delay solvent volatilization, wax will float to the surface of the stripping agent to form a film, the solvent is sealed inside. If the wax film is disturbed and cracks appear, part of the solvent will evaporate out, and all residues must be removed before sealing the plate stripping agent.
