Embodiment Construction

[0048] The weight ratio of raw materials in this embodiment is: 35 parts of tantalum-niobium tailings, 14 parts of carbide slag, 16 parts of cement, 14 parts of glass fiber, 3 parts of water glass, and 18 parts of water.

[0049] The fineness of the tantalum-niobium tailings is above 200 mesh, the cement is 32.5 grade ordinary Portland cement, the effective calcium content in the carbide slag is above 70%, the carbide slag is the waste slag discharged from the resin factory, and the glass fiber length is 7-9mm.

[0050] The production steps include:

[0051] (1) Ingredients

[0052] (2) loose glass fiber

[0053] Put all the glass fibers into the blender, then add water for loosening, the fiber loosening degree is 95%.

[0054] (3) Refining the glass fibers.

[0055] Refining parameters are: the speed is 40km / r, the feeding speed is 1250L / min, and the refining area is 2.2m 2 .

[0056] This process adopts a new type of conical refiner. The rotor of the refiner is a cantil...

Abstract

The invention discloses a fireproof plate. The fireproof plate is characterized by comprising the following raw materials in parts by weight: 30-32 parts of tantalum-niobium tailings, 13-15 parts of acetylene sludge, 8-10 parts of cement, 8-10 parts of glass fibres, 2-4 parts of sodium silicate, and 15-17 parts of water. Production for the fireproof plate comprises the following steps of: (1) proportioning; (2) loosening the glass fibres; (3) performing slurry-grinding treatment on the glass fibres; (4) preparing slurry; (5) flowing the slurry to produce a plate; (6) dehydrating the plate to form a blank; (7) cutting the blank; (8) curing the blank by high-temperature steam; (9) drying the blank; and (10) sanding the surface of the plate. The fireproof plate disclosed by the invention has remarkable economic and social benefits.

Description

technical field [0001] The invention relates to a fireproof board, in particular to a fireproof board and a preparation method. Background technique [0002] Traditional fireproof boards mainly use quartz powder, fly ash, etc. as silicon materials, and the production control is relatively mature. However, the cost of quartz powder in various places is generally high. As a result, the product cost is also higher, and the board produced by using fly ash is dark in color and low in strength. [0003] The main component of tantalum and niobium tailings is potassium albite feldspar powder, and is rich in flaky mica. As a silicon-rich material, feldspar powder is mainly composed of silicon dioxide, with a silicon dioxide content of more than 70%, and is rich in aluminum oxide, with a content of 15% to 17%. These silicon-aluminum components and calcium oxide can form excellent crystalline minerals such as calcium silicate hydrate and calcium plumbate hydrate under high-temperatu...
