Abstract
The invention relates to a disposable glass magnesium cement building mould plate, which is characterized in that raw materials, mixed according to mass ratio, includes 13.65% of coal ash, 9.83% of sawdust, 27.29% of magnesium oxide, 21.29% of magnesium chloride, 0.82% of glass fiber cloth, 0.11% of non-woven fabric, 16.37% of reclaimed materials and 10.64% of water. The method includes using aqueous solution of magnesium oxide and magnesium chloride as a main part of slurry, adding the coal ash and sawdust of a certain quantity, using the glass fiber cloth and the non-woven fabric to form a framework with improved tensile and bending resistance, and finally extruding and curing to form the mould plate. The method is simple and convenient, the mould plate produced by the method is high in strength and low in cost, the manufacturing cost of the mould plate is one third of that of traditional bamboo moulds, and the mould plate does not need to be demounted when used in underground engineering so as to be pretty convenient in use.
Description
Technical field
The invention belongs to the building template technical field, the disposable glass cement works of especially a kind of magnesium template and preparation method thereof.
Background technology
Building template is a kind of temporary structure, and it is made by design requirements, and concrete structure or member are shaped by position, the geometrical dimension of regulation, keeps its tram, and bears the weight of load.The use of building template has guaranteed the quality and the construction safety of concrete works, has accelerated construction speed and has reduced engineering cost.
The normal in the past mould material that adopts was a timber, and it is bigger that it builds quantities, and damaged a large amount of forests; According to incompletely statistics; Timber year, waste reached billion cubic meter, and this is for the deficient day by day China of the forest reserves, and the cancellation wood template is imperative.Thus, people use the iron and steel template to replace traditional wood template through research gradually; These iron and steel templates are firm not yielding, and it is safer, reusable to construct; But before each the use, all need to smear the material that plays isolation concrete surface and template inwall on the wall within it, after each the use, all will carry out the cleaning of template inner wall surface and heavy shaping work; The increase that this has all caused workload has reduced working efficiency, has improved construction cost.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide collocation a kind of disposable glass magnesium cement works template reasonable, with low cost.
The technical scheme that the present invention takes is:
A kind of disposable glass magnesium cement works template is characterized in that: its raw material comprises according to the following component of weight proportion blended:
And said magnesian activity is 45～65%, and magnesium content is 65～90%, and particle diameter is 180～200 orders;
The particle diameter of flyash and sawdust is less than 2 millimeters.
And said non-woven fabrics weight is every square meter 10 grams.
And said glasscloth weight is every square meter 150 grams.
And said reclaimed materials is that particle diameter is less than 2 millimeters.
Another object of the present invention provides a kind of preparation method of disposable glass magnesium cement works template, it is characterized in that: may further comprise the steps:
(1) configuration magnesium chloride brine;
(2) magnesium chloride brine, Natural manganese dioxide, sawdust, flyash and the reclaimed materials with step (1) mixes, and stirs, and forms mixed slurry;
(3) on the slab processing line, place mould, in mould, place non-woven fabrics and glasscloth;
(4) mixed slurry that step (2) is made injects mould, and opens the slab processing line, when extrusion roll presses down, layer of glass cloth and non-woven fabrics is laid in above-mentioned mixed slurry surface;
(5) make slab after the extrusion roll extrusion molding, be placed on the maintenance carriage after slab is cut off by specification requirement;
(6) slab after the maintenance carries out demoulding processing;
(7) after the demoulding,, promptly make disposable glass magnesium cement works template through cutting.
And the concentration of said magnesium chloride brine is 18～30 degree Beaume.
And said magnesian activity is 45～65%, and magnesium content is 65～90%, and particle diameter is 180～200 orders;
The particle diameter of flyash and sawdust is less than 2 millimeters.
Advantage of the present invention and positively effect are:
Among the present invention, form the main body of slurry, mix a certain amount of flyash and sawdust by the aqueous solution of Natural manganese dioxide, magnesium chloride; Re-use the skeleton that glasscloth and non-woven fabrics form to strengthen tension, flexural capacity, after extruding, maintenance moulding, making method is easy; The template strength that makes is high, and cost is low, is 1/3rd of traditional bamboo wooden model tool cost; When underground works is used, this template need not to remove, and is very easy to use.
