Problems solved by technology

[0003] In order to meet different construction needs, some manufacturers try to use expanded pearl powder and gypsum to produce calcium silicate boards with low density. Since the raw materials are gypsum, the strength of the produced calcium silicate boards is not enough, and the boards are easily deformed and resistant to moisture. , generally can only produce products with smaller specifications, which can no longer meet the needs of calcium silicate boards widely used in construction
Moreover, it is required to mix the expanded pearl powder and gypsum powder separately and evenly during manufacture, which requires additional equipment and manpower, which not only increases the cost, but also has a cumbersome process.

Embodiment 1

[0023] see figure 1 10% of cellulose fiber, 39.5% of calcium carbide mud, 43% of fly ash, 4% of cement, 3% of wollastonite, and 0.5% of chopped glass fiber are taken respectively in the present embodiment; first, the cellulose fiber is directly put into pulping In the vat, under the action of circulating water and debonder, it is dispersed into single fibers, and the natural color cellulose fibers that have been refined into the degree of percussion (°SR) 60-70 are mixed in turn in the pulping vat, and then mixed according to the proportion Add chopped glass fiber, calcium carbide mud, fly ash, and wollastonite under the action of the beater to make a slurry with a concentration of 10-14% and send it to the slurry storage tank. Function Send the slurry to the plate making machine to make slabs, after forming, cutting, stacking, pressurizing, steam curing in the steam curing room at 60-95°C for 4-6 hours, demoulding, and using 0.9-1.0Mpa steam Steam under pressure for 18 hours...

Embodiment 2

[0025] The present embodiment gets respectively 7% of cellulose fiber, 27% of calcium carbide mud, 18% of cement, 35% of fly ash, 8% of quartz sand, 5% of wollastonite, and makes carbide mud fly ash according to the steps of embodiment 1 Fiber reinforced building slabs. The properties of the plates are shown in Table 1.

Embodiment 3

[0027] The present embodiment gets respectively 8.5% of cellulose fiber, 40% of calcium carbide mud, 4% of cement, 38% of fly ash, 5% of quartz sand, and 4.5% of wollastonite, and the calcium carbide mud fly ash is made according to the steps of embodiment 1. Fiber reinforced building slabs. The properties of the plates are shown in Table 1.

[0028] Table 1 Performance indicators obtained from the test

Abstract

The invention discloses a carbide slurry fly ash fiber-reinforced architectural flat plate and a manufacturing method thereof. The carbide slurry fly ash fiber-reinforced architectural flat plate comprises the components in percentage by weight as follows: 36 to 45 percent of carbide slurry, 42 to 48 percent of fly ash, 6 to 8 percent of cement, 5 to 8 percent of quartz sand, 6.5 to 9 percent of cellulose fiber and 1 percent of poly-acetamide. The manufacturing method of the carbide slurry fly ash fiber-reinforced architectural flat plate comprises the following steps: step I, fiber refinement; step II, material feeding and pulping according to a formula; III, pulp storage, pulp discharge, pick-up and forming; step IV, processing forming; and step V, coating and packaging. The invention has the advantages that by utilizing local industrial waste namely the carbide slurry and the fly ash as main raw materials and utilizing the cellulose fiber as a reinforcing material, the architectural flat plate which has a shrinkage deformation coefficient larger than that of an ordinary calcium silicate plate, and better fireproof performance is produced; the radioactivity measured value of the architectural flat plate is 10 to 20 percent of the minimum value allowed by a national regulation, so that the architectural flat plate belongs to green environmentally-friendly products; and not only the production process satisfies the requirement of circular economy, but products are plates for the fields of wall bodies, ceilings and architectural acoustics, which satisfy the requirements of componentization, assembly and dry work for architectural products, so that the architectural flat plate belongs to high-level architectural material products in the architectural products.

Description

technical field [0001] The invention relates to a production process of building materials, in particular to a production of high-quality building panels by completely utilizing waste and a manufacturing method thereof. Background technique [0002] Calcium silicate board is one of the important wall materials in modern buildings, because of its light density (1.05-1.25 g / cubic centimeter), fire prevention (its combustion performance reaches GB8624 non-combustible class A), strong sound insulation, anti-corrosion and moisture-proof, High strength (13-17 MPa) and other characteristics, widely used in various types of modern buildings, as indoor partition walls, partition walls, floors, ceilings, furniture, etc. The existing calcium silicate board production mainly uses a large amount of raw minerals and their processed materials, such as quartz stone, slaked lime powder, etc. Due to the rising price of minerals, high production costs, the product market competitiveness is not...
