Calcium silicate board equipment is made of fiber reinforced material, silicon material and calcium material according to a certain ratio of silicon-calcium mixture, in saturated steam pressure curing hydrothermal synthesis reaction produced strength. Compared with fiber-cement products, it has lower thermal conductivity, lower shrinkage rate, and excellent fire-proof performance. It will not explode and burn in open fire, does not produce smoke and toxic gases. The production mechanism of strength is different, and the product performance is also different. The product surface treatment state is divided into the original board (code name YB) , one-sided sanding plate (code name DB) and double-sided sanding plate (code name SB) .
Calcium silicate plate equipment suitable for outdoor use, may withstand direct sunlight, rain, snow or frost. Suitable for long-term possible heat, moisture and non-recurrent frost and other environments. Such as underground facilities, hot and humid alternate or outdoor indirect sunlight, rain, snow, Frost and other environment. Can also be used indoors, may be subjected to heat and humidity, but will not be subject to frost. Such as walls, floors, brick lining or floor.
Fiber cement board, calcium silicate board, the first production of fiber cement board in our country is made of asbestos-reinforced fiber asbestos cement board, divided into construction of asbestos cement board and Electrical Asbestos Cement Board, a considerable part is also used as a heat-resistant plate in electric furnaces. At present, there are many kinds of fiber reinforced cement board, Asbestos, fiber plants, organic synthetic fiber are widely used, mix a variety of fibers as a reinforcement material to change and improve the performance of products. Non-asbestos fibre cement panels are the main varieties of today and in the future, and cementitious materials have also developed from a single Portland cement to the present cement + silica mixture for the production of low shrinkage fibre cement panels.
Fiber cement flat plate, generally from the board surface state, applicable environmental conditions, shrinkage of the board size, functional materials, application fields, the thickness of the board and board functions and other aspects of classification. [1] according to the surface treatment status, it is divided into original board (code name: YB) , single-side sanding board (code name: DB) and double-side sanding board (code name: SB) .
"1" original plate: that is, after forming the tube after hardening or plate pressure compacting plate, after curing hardening, the surface without any treatment, to maintain the original state of the surface molding plate, is the initial state of the plate. The surface smoothness and thickness uniformity of the original plate are poor.
"2" one-side sanding: refers to one side of the plate, according to the needs of subsequent processing technology, after the plate hardens to carry out a single surface sanding, sanding the surface of the original plate floating slurry, to meet the requirements of the smoothness required for processing, but can not reach the thickness and degree of double-sided sanding.
"3" double-sided sanding: refers to the net plate both positive and negative surface sanding treatment, improve the surface smoothness and thickness uniformity. First, for the subsequent processing of surface leveling, and second, sanding to the required thickness of the plate, so that the same plate thickness has a higher uniformity, in line with the needs of subsequent processing.
