Description
Technical field
The present invention relates to a kind of material of construction, be specifically related to a kind of calcium silicate board and manufacture method thereof be used to building inside and outside body of wall.
Background technology
The fibre-reinforced flyash pressure plate is one of materials for wall in a kind of modern architecture of making take siliceous material, calcareous material and fiber as main raw material.Possesses the irreplaceable advantage of other wallboards.Have fire prevention, protection against the tide, anti-sag, sound insulation, heat insulation, lightweight, without dust fall, dimensional stabilizing, indeformable, endurance quality is long, intensity is high, processing characteristics is superior, installation and maintenance are convenient, raw material is easily got, the second stage employ of some raw material meets the national green environmental protection, energy-saving and emission-reduction, the policy of low-carbon economy.
Existing calcium silicate board is take siliceous, calcareous material and fortifying fibre as main raw material, and moiety has following several types:
1, mainly by cement, quartz sand, fibrous.Cement, quartz sand account for larger proportion.The density of calcium silicate board is larger, and hardness is high, embrittlement, and later stage sanding, cutting are difficult for.
2, mainly by cement, slaked lime, quartz sand, fibrous.Slaked lime replaces the manufacture of cement cost high, and panel density is low, needs to consume a large amount of former mineral substance, does not meet the requirement of environmental protection.
3, mainly by kaolin, the expanded pearlite powder, gypsum forms.The insufficient strength of calcium silicate board, nail-holding ability is poor, and water-intake rate is high, and sheet material is out of shape easily.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome deficiency of the prior art, provide a kind of raw material sources abundant, cost is low, meets environmental requirement, high-compactness, and high nail-holding ability, intensity is good, fibre-reinforced flyash pressure plate and the preparation method of good processability.
Technical scheme: fibre-reinforced flyash pressure plate of the present invention is comprised of following component and mass percent:
Described flyash is comprised of following component and mass percent thereof:
Described pearlstone main component: SiO2 74.95%, and Al2O3 12.83%, and Fe2O3 0.21%, and CaO 0.08%, and other are 11.93% years old
The manufacture method of described fibre-reinforced flyash pressure plate comprises the steps:
One, is equipped with raw material by following component and mass percent thereof;
Cement 30～40%, asbestos 7～13.33%, waste cement paper bag 4～6.67%, flyash 40～50%, pearlstone 2～5%;
Two, with waste cement paper bag pulping, thin up, being stirred to mass percent concentration is 10～12%, sieves, thin up, transfers to the slurry of working concentration about 3%;
Three, with described asbestos opening, thin up, stirring, the 0.3h that loosens, the water of adding and the mass ratio of asbestos are 30: 1～40: 1, then add described cement, flyash, pearlstone, waste cement paper bag slurry, make slurry after mixing;
Four, with described slurry through head box cloth to felt, vacuum hydro-extraction is to mass percent concentration 70～75%, by the stacked forming tube compression moulding of cylinder, forming tube pressure is 2～3 MPas, through longitudinal and transverse trimming for forming, gets fibre-reinforced flyash pressure plate slab;
Five, with described fibre-reinforced flyash pressure plate slab patrix, place the 5000t chilling press to pressurize, moulding pressure is 800t～1200t;
Six, described fibre-reinforced flyash pressure plate slab is inserted in the precuring kiln, import pressure 0.25 MPa.60～70 ℃ of vapor cures of temperature, curing time 6h;
Seven, carry out high-pressure curing in the autoclave with inserting after the demoulding of described fibre-reinforced flyash pressure plate, importing vapor pressure is 0.8～1.0 MPa, 160～180 ℃ of temperature, the admission time is 3h, constant voltage constant temperature 13～14h, high-pressure curing time 16～17h, steam discharge temperature fall time 3h;
Eight, be≤10% with described fibre-reinforced flyash pressure plate work in-process with comb formula drying machine drying to water ratio.Bake out temperature summer is 95～115 ℃, and be 100～130 ℃ winter, then carries out limit facing sand light, the edging chamfering, and packing gets fibre-reinforced flyash pressure plate finished product.
Preparation method of the present invention simply may be summarized to be: material through pulping, loosen, pull an oar, store slurry, blowing, stream are starched, are vacuumized, moulding, the pressurization of colding pressing, precuring, the demoulding, pressure steaming, oven dry, sanding, edging chamfering, make finished product.Wherein key is: during the precuring behind (1) fibre-reinforced flyash sheet metal forming, pearlstone can effectively keep the skin wet inside and outside plate, accelerates the aquation xln of the things such as cement, flyash.Improve silicon salt body and the Tobemolai stone of sheet material in the steam pressure process and effectively form and hardness, can obviously alleviate panel weight.(2) improve the density of product after the moulding by the pressurization of colding pressing, improve nail-holding ability.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is:
One, utilize the three wastes as raw material, low production cost; Utilize waste cement paper bag pulping, making beating obtains the paper fiber, and utilization of waste material meets the environmental requirement of country; The flyash of coal-burning power plant's discharging is used, and has more great environmental protection and economic implications, reduces cement consumption, reduces cost, utilization of waste material, and refinforced cement condenses, and improves the hardness of fibre-reinforced flyash plate; The waste product that produces in manufacturing, transportation, installation process can be clayed into power and again be recycled, and does not produce secondary pollution.
Two, the product density is high, and nail-holding ability is high, and intensity is high, and is not yielding, fire prevention, and moisture-proof characteristic is good.
Three, technique is simple, of many uses, can use existing calcium silicate board production unit, need not transform, technical process is simple, easy to prepare, the fibre-reinforced flyash plate of production has the advantages that can saw, can follow closely, can dig, easily process, and is suitable for doing the high-speed railway acoustic barrier, build inside and outside wallboard, the floor, ceiling board, fire door etc.
