Generally, water glass with a certain number of moles, or glass water, that is, sodium silicate, is used to make plates of different specifications by high-temperature hot pressing process; if inorganic materials such as magnesite cement materials are used as perlite binders ( Can also be used to reduce the weight of the door core board), can be used as a partition wall and other architectural applications; or add some similar to urea-formaldehyde resin, polyester, protein, construction glue, 107 or 801 glue to make sticky Conjunction, because some will naturally release poison, and some will produce toxic gas through combustion, can be applied in sub-normal temperature or high temperature environment after fully placed, such as insulation board, sound insulation board, heat insulation board, etc.

If the inorganic bonding material is used as the main raw material, it belongs to the non-ionic and neutral state, and does not undergo displacement reaction with the metal molecules, and each of the perlite particles is in the state of coating. The film itself has high water resistance and hinders the pearl. The moisture absorption performance of the rock confirms the corrosion-free steel plate, the finished product has high strength, small thermal conductivity, moderate bulk density, good water-repellent performance, acid and alkali resistance, freeze-thaw resistance, high temperature resistance, good sound insulation, good elasticity and heat insulation. Flame retardant, dry and no black smoke, high temperature and high flame, no toxic gas after burning (according to GB/T20285-2006 standard) and GB12955-2008 "fire door" new standard, can be applied to fire shutter filling, fire door core The filling board can replace the replacement products of aluminum silicate cotton, rock wool, glass water type perlite board and foamed magnesite cement perlite board.
