Abstract
A dual-fibre gypsum board is prepared from gypsum powder, cube spar, trigger, expanded pearlite, filler and plant fibres through proportional mixing, adding water, stirring, pouring in mould, spreading fibrous net cloth on both surfaces, and natural curing. Its advantages are low cost, protecting environment, and high strength and quality of product.
Description
The present invention relates to a kind of dual-fibre gypsum board, belong to building material technical field.
The partition wall that uses in the present building, dalle etc., kind is a lot, Thistle board, double-reinforced gypsum plate, honeycomb paper plasterboard, gypsum particle board, paper fibrous plaster etc. are arranged, and what wherein have uses pouring forming technology production, the usefulness semidrying compression moulding explained hereafter that has.Wherein the timber intensity of producing with pouring forming technology is low, and is frangible in the carrying, scrap rate height during construction and installation; Sheet material with the compression moulding explained hereafter, although timber intensity height, but facility investment is big, and production efficiency is low, the product price height, thereby be difficult for enlarging on a large scale to popularize producing, therefore application also is restricted, and all is the base-material manufacturing with the semi-hydrated gypsum, and goods all need bake drying, both increased cost, again contaminate environment.
The objective of the invention is to propose a kind of dual-fibre gypsum board, is the raw material production plasterboard with the industrial waste, and makes the manufacturing process of plasterboard simple, and production cost is low, and turns waste into wealth, the protection environment.
The dual-fibre gypsum board that the present invention proposes, its prescription is:
Plaster of Paris (or water gypsum) powder 35～45%
Dehydrated gyp-(also claim anhydrite powder, granularity is greater than 200 orders) 28～38%
Exciting agent (60～70% Powdered burning potassium alum and
The mixture of 30～40% Powdered Tai-Ace S 150) 1～3%
Pearlstone 10～15%
Stopping composition 10～15%
Vegetable fibre 1～3%
With 100 parts of the above-mentioned dry material that mixes, join in 30～40 parts the water, stir into the mucilage shape, then it is poured in shop, two surfaces up and down and applied in the mould of fiber mesh cloth, through 0.1～1 hour curing molding, the demoulding was dual-fibre gypsum board of the present invention.
The used vegetable fibre of the present invention can be a rice husk, and its length is 5～20mm, also can be bamboo fibers, and its straight length is 2～20mm, and stopping composition wherein can be blast-furnace slag or flyash.
In the above-mentioned curing molding method, can under the pressure of 1～3mPa, above-mentioned mucilage shape mixture be sprayed into in-mold molding, or stir the back with stirrer and directly inject.As adopt formwork erection, then lay fiber mesh cloth in the both sides of formwork erection; As adopt the platform mould, and then spread fiber mesh cloth earlier, spray into gypsum slurry then, after wipeing off, strickle repaves one deck fibrous reticulum, then the roller aftershaping.
The dual-fibre gypsum board that the present invention proposes, utilize semi-hydrated gypsum and dehydrated gyp-mixture to be raw material, add a certain amount of light filler, staple fibre and additive, mix injection molding on the mould of having laid fiber mesh cloth at end end face in the back with water, make through roll-forming again.With the gypsum sheet material that method of the present invention is made, maintenance in physical environment does not need bake drying, has both reduced investment, has saved the energy again, has protected environment, and the product strength height, and quality is good.
Introduce embodiments of the invention below.
Embodiment 1:
Getting plaster of Paris is water gypsum 35%, 200 purpose dehydrated gyp-30%, the mixture 1% of Powdered burning potassium alum by 60% and 40% Powdered Tai-Ace S 150, pearlstone 12%, flyash 11%, rice husk 1%, last with the above-mentioned dry material that mixes 100 parts, join in 30 parts the water, stir into the mucilage shape, then it is poured in shop, two surfaces up and down and applied in the mould of fiber mesh cloth, through 0.5 hour curing molding, the demoulding is dual-fibre gypsum board of the present invention.
Embodiment 2:
Getting plaster of Paris is water gypsum 40%, 250 purpose dehydrated gyp-28%, the mixture 2% of Powdered burning potassium alum by 65% and 35% Powdered Tai-Ace S 150, pearlstone 15%, blast-furnace slag 13%.Bamboo fibers 2%, last with the above-mentioned dry material that mixes 100 parts, join in 35 parts the water, stir into the mucilage shape, under the pressure of 2mPa, above-mentioned mucilage shape mixture is sprayed into up and down shop, two surfaces applied in the mould of fiber mesh cloth, through 1 hour curing molding, the demoulding is dual-fibre gypsum board of the present invention.
Embodiment 3:
Getting plaster of Paris is water gypsum 42%, 200 purpose dehydrated gyp-35%, the mixture 1% of Powdered burning potassium alum by 70% and 30% Powdered Tai-Ace S 150, pearlstone 10%, flyash 10%, wood chip 2%, last with the above-mentioned dry material that mixes 100 parts, join in 40 parts the water, stir into the mucilage shape, adopt the platform mould, spread fiber mesh cloth earlier, spray into gypsum slurry with 2mPa then, after strickle is wipeed off, repave one deck fibrous reticulum, then the roller aftershaping.
