Embodiment 1

[0049] Example 1: Using wood shavings made from Sal from the Philippines, Portland cement, sulfate-containing salts, aluminum sulfate, calcium hydroxide, and carboxylic acid, a cement fiberboard was made according to the following proportions and methods: 15% of Sal shavings, 50% of cement, 3% of aluminum sulphur, 1% of calcium hydroxide, 1% of acetic acid, and 30% of water. After the production is completed, the bending test will be carried out.

Embodiment 2

[0050] Example 2: Using wood shavings made from Sal from the Philippines, Portland cement, sulfate-containing salts, aluminum sulfate, calcium carbonate, and carboxylic acid, a cement fiberboard was made according to the following ratio and method: Borneo Double tree shavings 15%, cement 50%, sulphur mud aluminum 3%, calcium carbonate 1%, acetic acid 1%, water 30%, the bending test is carried out after the production is completed.

Embodiment 3

[0051] Example 3: Using wood shavings made from Sal from the Philippines, Portland cement, sulfate-containing salts aluminum sulfate, calcium hydroxide, and oxalic acid, the cement fiberboard is made according to the following ratio and method: Sal wood shavings 15%, cement 50%, sulphur mud aluminum 3%, calcium hydroxide 1%, oxalic acid 1%, water 30%, the bending test will be carried out after the production is completed.

Abstract

The invention relates to the technical field of cement fibrolite plate manufacturing, in particular to a cement fibrolite plate manufacturing method. The cement fibrolite plate manufacturing method comprises the following steps that S1, material selection is performed for making materials, specifically, wood pulp fiber, cement, sulfate-containing salts, calcium salts, calcium hydroxide, distilledwater and carboxylic acid are selected; S2, the sulfate-containing salts are diluted into a solution, added to the wood pulp fiber and then mixed; S3, calcium hydroxide and the calcium salts are diluted into a solution and added to the wood pulp fiber, and then carboxylic acid is added to be fully mixed; S4, the mixed raw materials are dispersed uniformly by a dispersing machine, and paved and stacked; and S5, the uniformly stirred mixture is slowly sprinkled into a base plate in a forming frame, rolling and leveling are performed, water is removed, in order to facilitate demolding, an upper layer of plastic thin film and a lower layer of plastic thin film are additionally arranged, and after manual paving, the mixture is placed in a mold for pressurization. The cement fibrolite plate manufacturing method has the advantages of fireproof insulation, waterproof and moisture proof, light weight and high strength, simple construction, economical and beautiful properties, safe and harmlessproperties, long service life and the like.

Description

Technical field [0001] The invention relates to the technical field of cement fiber board manufacturing, in particular to a manufacturing method of cement fiber board. Background technique [0002] Cement fiberboard is a new type of building material made of siliceous and calcareous materials as the main raw material, with natural reinforcing fibers and auxiliary materials modified, after pulping, copying, pressing, and curing. The application range of cement fiberboard is very wide. Widely used, thin plates can be used as ceiling materials, and can be perforated as sound-absorbing ceilings. Conventional boards can be used for wall or decoration materials, thick boards can be used as LOFT steel structure floor boards, jumper boards, exterior wall hanging boards, clear water boards, etc. The standard length and width specifications of fiber cement boards are 1200*2400mm and 1220*2440mm Individual manufacturers can customize any specifications with a length of 2000-3000mm and a wi...
