Modified phenolic plate foam board

by:Ventech     2020-12-18
Production technology of modified phenolic foam board insulation board has two kinds, the first is a traditional method of intermittent mould process, using phenolic resin raw materials in the form of free foaming, spontaneous into large pieces of foam, then the secondary cutting according to need. This kind of process before 2009 did not use in building external wall insulation system, the vast majority of and tank insulation for pipe insulation.

the second kind is a new process of continuous production line is made of continuous production equipment after high temperature and high pressure molding, the phenolic resin foam layer compressed into raw materials needed for the thickness of the foam plank. This process for the production process by high temperature heating curing, pressure increase material compactness and obturator rate, greatly improving the material of product performance, and retain the foam density surface layer which is formed by the surface effect, the product of the coefficient of thermal conductivity, bibulous rate, strength and off the powder with intermittent mold hair products are of great difference.
