[0046] In a first aspect, in at least one embodiment, a method for preparing a calcium-silicon board slab is provided, comprising the following steps:
[0047] Transport the prepared slurry to the preforming device through the feeding device;
[0048] Vacuum dehydration is carried out during the preforming process with the preforming device, and the dehydrated material adheres to the feeding blanket under the action of the preforming device;
[0049] The material layer on the feeding blanket is driven by the transmission mechanism to be wound onto the forming cylinder. When the number of winding layers reaches the requirement, it will be pressed and formed by the forming cylinder to obtain a calcium-silicon board slab.
[0050] In order to alleviate the technical problem that the traditional production process cannot produce large-size, flat calcium silicate sheets of 1-2 mm and calcium silicate thick plates of more than 20 mm, the present invention provides a rolling feeding (o...

[0122] A preparation method of calcium silicon board, comprising the following steps:
[0123] Mix 35 parts by weight of diatomite, 35 parts by weight of lime, 25 parts by weight of quartz powder, and 5 parts by weight of wood fiber, add 110 parts by weight of water to stir and mix thoroughly, pump the mixed materials into five material barrels, and Add red, orange, yellow, green and purple pigments into the five material barrels respectively, and feed them into the distributing pipes through the feeding pumps respectively, leading to five different preforming cylinders, and open the appropriate distributing pipes to make the preformed Appropriate thickness of the preformed plate is formed on the forming cylinder, and finally the preformed plate of five colors formed on the five preforming cylinders is rolled and rolled by the forming cylinder, and the pigments penetrate and fuse with each other, and after dehydration, a gorgeous autumn color silicon is formed. Calcium slab;
