Abstract
The present invention is a kind of architectural light-fibre glass reinforced cement slab that is used for, and is called for short light grc board, and its manufacture method is to cut-the gunite moulding with short with low alkali cement slurry and alkali resistant glass fiber.Characteristics such as the preparation of slurry is to add admixtures such as pearlstone and thickening material in cement, and molding technological condition is similar to common GRC plate, makes product to have lightweight, and is high-strength, fire-resistant, do not fire, corrosion-resistant, heat insulation can be used for the interior exterior wall finishing of all kinds of buildingss.
Description
A kind ofly be used for architectural light-fibre glass reinforced cement slab, be called for short light grc board, the general glass fiber reinforcement cement board of characteristics volume to weight ratio of this product innovation is little many, and can satisfy the requirement of architectural processing, installation.
This matrix material of glass fiber reinforcement cement board (being called for short the GRC plate) of having developed excellent property with short cutting-spray technology technology during China " six or five " has the intensity height, and bending strength reaches 200Kg/cm
2More than, resistance to impact shock 5Kgcm/cm
2And rigidity is big, quality is hard, and the sheet material of making can not be processed again, so generally all make ribbed plate, give on the rib and bury bolt or other web members, give embedded part by this kind and be connected with framework, therefore, the application of this kind GRC plate is subjected to certain limitation, the general outer shell structure that is used for buildings more, and cost is high.
Task of the present invention is the requirement that is not suitable for some use range at common GRC plate, and the composition by changing it to be changing its physical and mechanical properties, to satisfy the demand of present construction sector for the superior light grc board of processing, installation capability.
Light grc board of the present invention is mainly by low alkali cement, and alkali resistant glass fiber and light material composition make in order to the below method:
(1) this kind sheet material is to cut-the gunite moulding with short with low alkali cement slurry and alkali resistant glass fiber.
(2) proportioning of cement slurry is as follows:
Low alkalinity cement 100
Pearlstone 10～30
Thickening material 0.3～1
Water cement ratio (W/C) 0.7～0.95
(3) alkali resistant glass fiber content is looked light grc board requirement of strength difference, and add-on accounts for 2～7% of light grc board material gross weight.
(4) the spray technology parameter is as follows:
Spray air pressure 3atm
Slip denseness 11～13cm(measures with mortar consistency tester)
Slip emitted dose 6～15Kg/ branch
Fiber jet amount 200～800g/ branch
(5) curing condition, available natural curing or vapor cure.
More than thickening material in the prescription of (2) cement slurry, can be gelatin, vegetable jelly, 107
#Glue or polyvinyl alcohol etc. have the colloid of thickening power, in addition in order to delay the time of coagulation of cement slurry, keep plasticity, can add lemon wood acid below 0.3 as retardant, in order to reduce water cement ratio, improve workability and intensity in addition, can add the water reducer below 0.7, as wooden calcium, naphthalene water reducer etc., its effect is to guarantee slurry stability in operation.
Below in conjunction with process flow sheet technological operation is described below:
Cooperate ratio with low alkali cement according to slurry, water, admixture, perlite measures respectively, earlier admixture (is comprised thickening material, water reducer and retardant) in water, dissolve, again and low alkali cement, pearlstone is poured stirrer together into and is made uniform slip, in the injection squeegee pump, start squeegee pump, slip just by force feed to the slip spray gun, then under compressed-air actuated effect, spray from spray gun, simultaneously, woven glass roving fabric is cut after fiber spray gun sprays through the cutting unit weak point, and two strands of jets aloft are deposited on the template behind the uniform mixing, again through roll extrusion, troweling has just been finished the forming operation of light grc board.New moulding light grc board leaves standstill the demoulding after 24 hours at ambient temperature, carries out maintenance again, can adopt natural curing or vapor cure.
Classify 3 embodiment of the present invention in the table 1 as.
The overall technique performance such as the table 2 of light grc board of the present invention:

Advantage of the present invention and effect:
(1) the present invention implements in the our factory, can form to the end of the year 90 and produce 210000 m per year
2Throughput, can be the profit of the newly-increased 4,200,000 yuan of output values of our unit and 80～1,000,000 yuan every year.
(2) light grc board subtracts half than common GRC plate unit weight, rigidity descends, and available general wood working tool is processed it, can saw, bores, follows closely, dig, at random do various surface decorations, construction install convenience, technical feature are very superior, at Tiantan Hotel, the restaurant, Asia, realm of art and literature restaurant uses square meter more than 40,000 in the heavy constructions such as Asian Games Village engineering, be subjected to user's very big welcome.
(3) light grc board can be used as permanent mold, and intensity and toughness all can meet the demands.
