Abstract
The invention discloses a preparation method of haydites by using the smelting magnesium slag, wherein, 80-90 weight portions of smelting magnesium slag, 0-20 weight portions of cement, 1-10 weight portions of gypsum and 0.05-0.5 weight portions of gas former are mixed evenly and then added and mixed evenly with adequate water and then are made into grains with pelleting machine, therefore, the product is obtained after natural curing for 2 to 7 days or steam curing for 15 to 24 hours. The invention has simple process and can replace the haydites made from other materials and be applied in construction industry to improve the waste utilization of the magnesium-smelting industry, thereby increasing economic benefit and reducing environmental pollution.
Description
Technical field
The present invention relates to a kind of preparation method of porcelain granule, particularly a kind of method of utilizing magnesium-smelting reduction slag to prepare haydite.
Background technology
In the vacuum metling process of reduction method magnesium, can produce a large amount of magnesium reduction waste residues.These waste residues are usually as waste disposal, but these magnesium reduction waste residues are to be pulverous under the normal temperature, be difficult for condensing, usually need just can condense slowly more than 28 days, therefore before the powdered waste residue does not condense, the waste residue of stacking is met wind and is easy to produce airborne dust, serious environment pollution has very strong contaminative, be can not be careless topple over, they can destroy the ecotope and the eubiosis, therefore stack again after also needing waste residue handled, need special stockyards to stack, also need trucking costs and set up the expense in stockyard and stack these waste residues, increase the cost of business processes waste residue, and taken valuable land resources.
Summary of the invention
The objective of the invention is to: a kind of method of utilizing magnesium-smelting reduction slag to prepare haydite is provided.To substitute the haydite of other materials preparation, be used for building trade, solve the waste residue utilization of refining magnesium industry, increase economic efficiency, reduce environmental pollution.
Technical scheme of the present invention: utilize magnesium-smelting reduction slag to prepare the method for haydite, it is characterized in that: it is to make with the following weight parts proportion raw material;
Magnesium-smelting reduction slag 80-90 part; Cement 0-20 part;
Gypsum 1-10 part; Foaming agent 0.05-0.5 part.
The above-mentioned magnesium-smelting reduction slag that utilizes prepares the method for haydite, preferably makes with the following weight parts proportion raw material;
Magnesium-smelting reduction slag 85-88 part; Cement 7-15 part;
Gypsum 4-8 part; Foaming agent 0.1-0.3 part.
The aforesaid utilization in the method that magnesium-smelting reduction slag prepares haydite, described magnesium-smelting reduction slag are the magnesium reduction waste residues that produces with in the reduction method vacuum refining magnesium process, or the magnesium reduction slag that obtains of other method.
The aforesaid utilization in the method that magnesium-smelting reduction slag prepares haydite, described gypsum is the plaster of paris, phosphogypsum or the industry byproduct desulfurated plaster of sulfur acid calcium.
The aforesaid utilization in the method that magnesium-smelting reduction slag prepares haydite, described foaming agent is meant aluminium powder aluminium powder, hydrogen peroxide, carbide of calcium or chlorinated lime.
The aforesaid method of utilizing magnesium-smelting reduction slag to prepare haydite is made by following step;
A, with magnesium-smelting reduction slag, cement, gypsum, whipping agent mixing, add an amount of water and stir, make particulate state with granulation machinery, the A product;
B, with A product natural curing 2-7 days or vapor cure 15-24 hour, finished product.
Compared with prior art, the invention provides a kind of method of utilizing magnesium-smelting reduction slag to prepare haydite.This method is a main raw material with a large amount of magnesium reduction waste residues that produce in the refining magnesium process, adds suitably batching, and adopts and exempt from the agglomerating preparation method, make haydite, make waste residue become available material, both alleviated the pollution of industrial residue, provide useful material for building trade again environment.The present invention fills a prescription rationally, making method rationally and be easy to grasp, have be easy to produce, with short production cycle, production cost is low, the characteristics of good product effect.Improve economic benefit of enterprises, and reduced the industrial residue environmental pollution.
