Rock wool insulation board production process: wool board is made of basalt (slag) by the blast melted into a liquid, stick spun by high speed centrifugation, the high-speed air flow blowing, forming a small fiber fineness, sandwich panel manufacturers, flexibility strong wool board fibers, injection Bumian method using synthetic wool board special glue which is injected into rock wool fibers, the wool fiber composite, and then by the fixed speed pendulum, uniform Bumian method rockwool fiber Bumian, the track speed control, track up and down compression, compressed into rock wool board, rock wool board density level of the track speed control, and the pendulum fall cotton decision. After the pendulum Bumian wool, and down by the track compression, transfer to a high temperature oven, which was dried, made into wool board after installation cycle is short: rock wool sandwich panels, sandwich processing, because the field no secondary processing, not only to keep the surroundings clean and tidy, does not affect the normal running of other processes, sandwich panels, and can greatly shorten the installation cycle sheet, Anyang sandwich panel, rockwool sandwich daily average installation area 600 to 800 square meters. Anti-scratch protection: rock wool sandwich panel production, can be attached to the surface of a polyethylene adhesive protective film to prevent transportation and installation process steel surface coating being scratched or worn.
