Embodiment 1

[0037] The preparation technology of the calcium silicate board that the present invention proposes, the process is as follows:

[0038] The treatment process of step (1) is as follows: First, put the pulp board paper into the pulper, add quantitative water to fully relax, and the relaxation time is 40 minutes; the pulp after relaxation is pumped into the pulp tank, and then diluted with water to a lower concentration Enter the double-disc refiner for coarse grinding.

[0039] The treatment process in step (2) is as follows: First, add the fibers into the pulper, add quantitative water to fully relax; pump the loose fiber mixed pulp into the countercurrent mixer, add an appropriate amount of pulp after fine grinding, and then sequentially Add an appropriate amount of lime powder, quartz powder, and cement, and stir well in a countercurrent mixer to make a slurry.

[0040] The process in step (3) is as follows: First, the slurry is quantitatively and uniformly supplied to the ...

Embodiment 2

[0045] The preparation technology of the calcium silicate board that the present invention proposes, the process is as follows:

[0046] The process of step (1) is as follows: firstly, put the pulpboard paper into the pulper, add quantitative water to fully relax, and the relaxation time is 60 minutes; the pulp after relaxation is pumped into the pulp tank, and then diluted with water to a lower concentration Enter the double-disc refiner for coarse grinding.

[0047] The treatment process in step (2) is as follows: First, add the fibers into the pulper, add quantitative water to fully relax; pump the loose fiber mixed pulp into the countercurrent mixer, add an appropriate amount of pulp after fine grinding, and then sequentially Add an appropriate amount of lime powder, quartz powder, and cement, and stir well in a countercurrent mixer to make a slurry.

[0048] The process in step (3) is as follows: First, the slurry is quantitatively and uniformly supplied to the single-di...

Description

technical field [0001] The invention relates to the technical field of calcium silicate boards, in particular to a preparation process of calcium silicate boards. Background technique [0002] Calcium silicate board, as a new type of green and environmentally friendly building material, not only has the functions of traditional gypsum board, but also has the advantages of superior fire resistance, moisture resistance and long service life. It is widely used in suspended ceilings and partition walls of industrial and commercial engineering buildings, home decoration, Lining boards for furniture, billboards, ship partitions, warehouse sheds, network floors, and wall panels for tunnels and other indoor projects. [0003] Calcium silicate board is made of loose short fibers such as inorganic mineral fibers or cellulose fibers as reinforcing materials, and siliceous-calcic materials as the main cementing material. Plates made of calcium silicate gel. It is a new type of buildin...
