Abstract

The invention relates to a fiber-reinforced fly ash pressure plate and its manufacturing method. Composed of cement, asbestos, waste cement paper bag, fly ash, and expanded perlite, the fly ash pressure plate is prepared by the processes of: pulping, releasing, beating, pulp storage, pulp discharge, pulp flow, vacuum pumping, molding, cold pressing pressurization, precuring, demoulding, autoclaving, drying, sanding, edging and chamfering. The invention provides the fiber-reinforced fly ash pressure plate with the advantages of rich raw material sources, low cost, environment friendliness, high density, great nail-holding power, good strength as well as good processability and its preparation method.

Description

technical field [0001] The invention relates to a building material, in particular to a calcium silicate board used for building inner and outer walls and a manufacturing method thereof. Background technique [0002] Fiber reinforced fly ash pressure plate is one of the wall materials in modern buildings made of siliceous materials, calcareous materials and fibers as the main raw materials. It has irreplaceable advantages of other wall panels. It is fire-proof, moisture-proof, subsidence-resistant, sound-insulating, heat-insulating, lightweight, dust-free, dimensionally stable, non-deformable, long-lasting, high-strength, superior in processing performance, easy to install and maintain, easy to get raw materials, and secondary use of some raw materials It is in line with the national policy of green environmental protection, energy saving and emission reduction, and low-carbon economy. [0003] The existing calcium silicate board uses silicon, calcium materials and reinfor...
