Abstract
The invention provides a method for preparing a microcrystalline material from quartz sand waste residues.The method comprises the following steps that 1, the quartz sand waste residues are taken, dried, smashed and sieved with a 80-mesh sieve; 2, the sieved quartz sand waste residues are conveyed to a stock bin through a belt conveyor; 3, quartz sand waste residue powder obtained in the step 1 is lifted to a melting furnace through an elevator for high-temperature melting; 4, the product obtained in the step 3 is washed with water for quenching through a pressurized water gun, the product is water-quenched into particles which are smaller than 6 mm, and the particles are sieved and conveyed to a stock bin through a vibrating conveyor; 5, intermediate product raw materials are weighed and taken from the stock bin, and then compression molding and sintering molding are conducted; 6, obtained products are pushed into a crystallization annealing furnace for high-temperature molding and crystallization annealing, molded and crystallized products are ground, polished, cut and trimmed, and a microcrystalline material finished product is obtained, wherein the temperature of the high-temperature melting process is 1,400-1,600 DEG C, the melting time is 1-2 h, the sintering temperature is 1,000-1,200 DEG C, and the sintering time is 2-3h.According to the method for preparing the microcrystalline material from the quartz sand waste residues, the waste residue use ratio is high and can reach 70%.
Description
Technical field
The present invention relates to a kind of method utilizing quartz sand waste residue to prepare micro crystal material, belong to waste recovery technical field.
Background technology
Micro crystal material, is devitrified glass also known as microcrystalline jade or glass-ceramic.Being comprehensive glass, be the novel construction material just developed of a kind of foreign country, its formal name used at school is called glass quartz.Devitrified glass and our common glass seem to differ widely.It has glass and the double grading of pottery, and the atomic arrangement within simple glass is not have well-regulated, and this is also one of the reason of Glass breadks easily.And devitrified glass is as pottery, it is made up of crystal, say, that its atomic arrangement is regular.So, devitrified glass is higher than the brightness of pottery, stronger than glass toughness.
In the industrial production, mining to produce substantial amounts of mine tailing, the industry such as metallurgical industry and inorganic chemical industry can produce a large amount of waste residue in process of production, treatment of urban garbage can produce a large amount of solid waste, these mine tailings and waste residue typically use the mode of stacking to process, do not only take up a large amount of soil, also can because of infiltration polluted underground water resource.On the other hand, garbage main component typically exists with oxide forms such as SiO2, Al2O3, CaO, MgO, and these oxides are also to produce the important source material needed for devitrified glass.Producing devitrified glass with mine tailing and industrial residue, its surcharge is high, is possible not only to economize on resources, reduce the discharge of trade waste, alleviate ambient pressure, it is also possible to turn waste into wealth, bring huge economic and social benefit, be devitrified glass research and the main development direction produced.
Existing industrial residue produces in the method for micro crystal material, inefficient to waste residue.
