Abstract
The invention discloses a method for producing hollow glass spheres, which comprise the following steps: mixing quartz sand, feldspar, soda ash, calcium carbonate, calcium sulfate, talcum, soluble glass, borax, white copperas zinc sulfate and zinc oxide solid raw materials and performing ball milling, passing through a sieve with 500 meshes, adding paste containing starch, cellulose and water, mixing and uniformly grinding, performing spray drying, calcinating through a spheroidizing furnace at 1100-1200 DEG C, and cooling to obtain the hollow glass spheres. According to the method, the production cost is greatly reduced.
Description
Technical field
The present invention relates to glass microballon, specifically the manufacture method of hollow glass micropearl.
Background technology
Hollow glass micropearl is a kind of type material that development in recent years is got up, and its density is low, good heat insulating, is widely used in various light material, lagging material.
CN101704632A discloses a kind of hollow glass micropearl and preparation method thereof, 1. prepare burden, frit is made up of the raw material of following weight proportioning: SiO2 70% ~ 80%, Na2O 8% ~ 12%, CaO 5% ~ 9%, B2O3 2% ~ 6%, SO3 0.2% ~ 0.5%, K2O or Li2O 0 ~ 5%, ZnO or BaO 0 ~ 5%, Al2O3 0 ~ 3%; Chemical constitution formula according to frit takes raw material and mixes; 2. shrend is melted: dropped in melting furnaces by the frit mixed and found, glass smelting temperature is 1350 DEG C ~ 1450 DEG C, and melting time is 1 ~ 2 hour, then pours the glass metal melted in watch-quench tank shrend; 3. dry crushing and classification: dried by frit good for shrend, then grinding classification, crushing and classification adopts jet mill grinding, and glass powder particle size range used is 4 ~ 40 μm; 4. hollow nodularization: the glass powder that classification is good is passed through into the hollow nodularization of pearl stove; Hollow nodularization temperature is 1100 DEG C ~ 1300 DEG C; 5. sorting is collected: collected by the glass powder passing through into pearl stove heated, then isolate hollow glass micropearl by floating method; Its granularity of gained hollow glass micropearl concentrates on 10 ~ 60 μm, density≤0.3g/cm3, ultimate compression strength >=12Mpa, its floatability: >=95%.
CN102320743A discloses a kind of high strength aluminosilicate hollow glass microsphere and preparation method thereof, its chemical constitution is as follows: SiO2 60% ~ 75%, Al2O3 10% ~ 15%, Na2O 10% ~ 15%, CaO 1% ~ 3%, MgO 0 ~ 1%, S 0.02% ~ 0.5%, R2O 0 ~ 3%, Fe2O3 0 ~ 3%, in described R2O, R is the basic metal beyond Na; Described hollow glass micropearl, density 0.2 ~ 0.6g/cm3, ultimate compression strength 3 ~ 130MPa, size≤80 μm, floating rate≤95%, softization Wen Du≤750 DEG C.Hollow glass micropearl of the present invention not only can be used for the every field of plain hollow glass microballon application, and be applicable to plain hollow glass microballon and be beyond one's reach, there are the high temperature of particular requirement, high pressure field, if well depth in the hollow glass micropearl solid buoyancy material of 1000m, 2000m, 4500m and following use under water, oil drilling is more than the well cementation hollow glass micropearl of 6000m and the hollow glass micropearl for plastic hot extrusion moulding.
Above-mentioned two parts of patent production methods are complicated, and cost is high.
Summary of the invention
The object of the present invention is to provide a kind of method of low-temperature sintering hollow glass micropearl, greatly can reduce production cost.
The manufacture method of hollow glass micropearl of the present invention is: be quartz sand 40-55% by weight ratio, feldspar 8-16%, soda ash 6-11%, calcium carbonate 5-15%, calcium sulfate 2-5%, talcum 0-1.5%, water glass 0-2.5%, borax 3-10%, zinc sulfate 0-1.5%, the solid material mixing and ball milling of zinc oxide 5-12%, cross 500 mesh sieves, add the Mierocrystalline cellulose of starch containing 2-5wt% and 3-6wt% and the paste of water composition, the weight ratio of solid material and paste is 1 ︰ 1-2.5, mixed grinding is rear spraying dry evenly, through the balling furnace calcination of 1100-1200 DEG C, cooling becomes hollow glass micropearl.
Above-mentioned starch can be flour, Tapioca Starch, ground rice, amylodextrin.
C also containing 0.1-0.5 in paste
