Description
Technical field
The invention belongs to glass manufacturing area, relate in particular to the production method of the dull and stereotyped cover plate of a kind of sodium.
Background technology
Glass is divided into oxide glass and nonoxide glass by composition, and oxide glass is divided into again silicate glass, borate glass, phosphate glass etc.Silicate glass refers to the glass that basal component is silicon-dioxide, it is wide in variety, purposes is wide, press the difference of dioxide-containing silica in glass, be divided into again: silica glass, soda glass etc., soda glass is with quartz sand, soda ash, Wingdale, feldspars etc. are main raw material, through 1500-1600 ℃ of high-temperature fusion, moulding, and through the quick cooling and amorphous noncrystalline solid material that makes, its chemical composition is very complicated, be mainly silicon-dioxide, sodium oxide, calcium oxide, also contain in addition a small amount of iron, aluminium sesquioxide, magnesium oxide, potassium oxide etc., this glass is called soda glass.Soda glass is with low cost, easy-formation, suitable for mass production, its output accounts for 90% of practical glass, it is of many uses, can be used to produce glass bottle and jar, sheet glass, vessel, bulb etc., and we also belong to the deep processed products of soda glass or soda glass by common windowpane used more.But the ability of common soda glass protection ray, in order to meet the needs of some specific occasions, need to add some materials, strengthens the ability of sheet glass protection ray.The present invention be take the electric smelting continuous induction melting furnace as equipment, take quartz sand, soda ash, Wingdale, feldspar, zircon, sodium dichromate 99, nickel oxide, boron oxide is raw material, obtain the dull and stereotyped cover plate of sodium by batching, blending, melting, moulding, annealing, the operation such as cooling, wherein sodium dichromate 99 has the effect that absorption is ultraviolet, nickel oxide absorbs infrared rays, boron oxide has the absorption neutron current, therefore, this cover plate has the ability of stronger protectiving ultraviolet, infrared rays, neutron current, also has the ability of certain absorption portion visible ray.It is simple that this production method has technique, and raw material sources are convenient, and technical maturity, pollution-free is applicable to the series of advantages such as suitability for industrialized production.
Summary of the invention
The problem that the present invention mainly solves is to provide the method for the dull and stereotyped cover plate of a kind of suitability for industrialized production sodium, it is raw material that the method be take quartz sand, soda ash, Wingdale, feldspar, zircon, sodium dichromate 99, nickel oxide, boron oxide, obtain the dull and stereotyped cover plate of sodium by batching, blending, melting, moulding, annealing, the operation such as cooling, have that production technique is simple, raw material sources convenience, technical maturity, a row advantage such as pollution-free.The weight percent of the raw material that the present invention uses is: quartz sand 60%-62%, soda ash 18%-20%, Wingdale 13%, feldspar 4%, zircon 1%, sodium dichromate 99 0.5%, nickel oxide 0.5%, boron oxide 1%.
The present invention can be achieved through the following technical solutions:
The method of the dull and stereotyped cover plate of a kind of suitability for industrialized production sodium is characterized in that following steps form:
(1) quartz sand of formula ratio, soda ash, Wingdale, feldspar, zircon, sodium dichromate 99, nickel oxide, boron oxide are mixed to rear even blend, compound is sent into to the electric smelting continuous induction melting furnace, temperature in the electric smelting continuous induction melting furnace is elevated between 1570 ℃-1590 ℃, keep this temperature 20-22 hour, make compound reach molten state, obtain sodium cover plate molten mass.
(2) make tin tank heating tin in molten tin bath in molten state, the tin degree of depth of molten state should be more than 30 centimetres, quantitative sodium cover plate molten mass is flowed into to molten tin bath certainly, sodium cover plate molten mass floats over the surface of tin liquor because proportion is little, under the acting in conjunction of gravity and surface tension of liquid, form tabular sodium cover plate molten mass, now slowly tabular sodium cover plate molten mass is cooled to below 900 ℃ and makes it to become solid, then solid glass is pulled out to molten tin bath, send into annealing furnace, at annealing furnace, progressively lower the temperature, when temperature is down to 150 ℃ of left and right, annealing is complete, finished product is sent in air, obtain finished product naturally cool to normal temperature in air after.
Temperature of fusion in electric smelting continuous induction melting furnace described in above-mentioned steps (1) is 1580 ℃, and fusing time is 21 hours.
The present invention compared with prior art has the following advantages:
(1) technique is simple, production cost is low, and raw material sources are convenient, technical maturity, pollution-free.
(2) be suitable for industrialized mass production, quality product is high.
