Low Density Insulation of Inorganic Powder with Supporting Structure Using Expended Perlite, its Manufacturing Method and Making Machine
The invention method of producing low density inorganic powder insulating material having a low density molded structure with a binder (binder) expansion peorayiteu (perlite) without the use of and relates to its molding machine, particularly by using the expansion peorayiteu the irregularly shaped glass particles to evenly distribute the peorayiteu particle shape for improved molding strength at low density to form a structural frame (framework) between synthetic silica according to the low density and increased specific surface area (conduction and convection block) is to generate the heat conductivity reduction. Through In low specific gravity and the specific surface area is large laminated material to compression molding, or compression roller with a molding machine with a plate and a filter of perforated structure mounted to remove the pressure and the air in the molded product generated upon compression of the use of raw material in the production method of the heat insulating material It made of a laminated material, by compressed economical and physical properties to the preparation method thereof and a molding machine of low density inorganic insulator powder having a forming structure using a high expansion peorayiteu.
