Abstract
The invention relates to a production formula for alkali-resistant glass marble in building material industry, a production method and a production kiln thereof. The invention is reasonable in selecting weight proportions of ingredients, which is favorable for the control of quality system, and the produced finished product of the glass marble has high clarity and good quality; the entire technological process consists of screening, weighting and mixing raw materials, founding and discharging, the technology is simple and the operation is convenient; using a horseshoe-fired furnace for producing the alkali-resistant glass marble solves the technical prejudice in a long term that the horseshoe-fired furnace is unsuitable for the production of the alkali-resistant glass marble; a general glass marble kiln is utilized to realize the production of the alkali-resistant glass marble without improving kiln refractory, which has the advantages of large production scale, easy control and regulation for the production process, good scale effect and prominent energy-saving effect; the cost is dramatically reduced while the production rate is greatly improved in contrast to a full-electric melting kiln.
Description
Technical field
The present invention relates to production formula and the production method and the plant-scale equipment of a kind of alkali-resistant glass marble in the building materials industry, especially for production formula and the production method and the production kiln of a kind of alkali-resistant glass marble of alkali resistant glass fibre production.
Background technology
Alkali resistant glass fibre is to make the glass fiber reinforced cement goods enhancing base material of (being called for short the GI bare hill), because this kind goods have light weight, intensity height, do not fire, designability is strong, easy-formation, long service life, cost is better than advantages such as magnesium cement far below glass reinforced plastic, magnesium cement and long-term behaviour.At home, be widely used in outer building and the civil engineering work, not only be used for cold district, and extend to the more existing product scope of making by glass reinforced plastic formula magnesium cement usually as materials for wall.But because zirconic content and contains titanium oxide (TiO about 6% generally up to more than 14% in its Chemical Composition
2), therefore, temperature of fusion is up to more than 1600 ℃ when producing it as the glass sphere of raw material, and it is bigger to found difficulty.
At present, a kind of method of producing alkali-resistant glass marble is to adopt the production of all-electric melting kiln, though this mode of production scaling loss and fly upward the loss less, but exist industrial scale little, every kiln only can be established 1～2 group of apparatus for making pearl ball (2～4T/ daily output), and the glass metal surface temperature is low in the power consumption height, stove, the temperature field is inhomogeneous, and poor product quality, bubble is more and disadvantage such as production cost height.
Patent Office of the People's Republic of China discloses the patent of invention (notification number: CN1500753) of a kind of denomination of invention for " a kind of production method of alkali-resistant glass marble ", promptly adopt the horse shoe flame kiln to produce alkali-resistant glass marble, mainly be to adopt natural gas to make fuel, and kiln each several part structure is adopted high temperature resistant zircon corundum brick or silica brick is liner, to satisfy the temperature of fusion of alkali-resistant glass marble production requirement.This method adopts quartz sand, calcite, zircon sand, rutile, fluorite and saltpetre, soda ash and introduces the part grog as former, auxiliary material, through pulverizing, the preparation compound, and send in the Sweet natural gas water chestnut melting furnace that high temperature resistant zircon corundum brick is a liner and found, cooling, clarification, system ball are after anneal and make the alkali-resistant glass marble that contains high zirconia.This invention admixtion flies upward greatly, and glass metal melting time in kiln is shorter, and the glass sphere quality of being produced is still undesirable, and glass ball clarity is not high; This production method also exists material burst temperature lower in addition, has both easily produced the crystallization devitrification, influences the balling ratio of glass ball again, and has a strong impact on quality product.In addition, this glass sphere prescription summation of respectively filling a prescription under the situation of not considering loss on ignition surpasses 100% obviously unreasonable.Simultaneously, this method is adopting the horse shoe flame kiln to produce in the process control procedure of alkali-resistant glass marble, because still there is following problem in the factor of furnace construction own: 1, with respect to traditional horse shoe flame kiln, it is liner that this patent adopts high temperature resistant zircon corundum brick or silica brick, has promoted production cost; 2,, cause that kiln temperature fluctuation is big, tangible temperature head appears in width in the kiln pond because the width in fusion pond is bigger; 3, going deep in the fusion pond along with combustion stroke, combustion-supporting power reduces gradually, flame is decayed gradually, and burning brings waste gas progressively to produce and gather not to the utmost, thereby stops up the work-ing life that port causes the reduction of glass sphere make efficiency and quality product is low even reduce kiln; Simultaneously because the accumulation of waste gas also will cause environmental pollution.
Patent Office of the People's Republic of China also discloses the patent of invention (notification number: CN1248980C) of a kind of denomination of invention for " a kind of production method of alkali-resistant glass marble and production kiln ", adopt quartz sand, zircon sand, rutile, calcite, fluorite and saltpetre, soda ash or introduce the part grog again as former, auxiliary material, through pulverizing, the preparation compound, found, cooling, clarification, the system ball is after anneal and make high-zirconium oxide alkali-fast glass ball; And the kiln of fusion cast glass liquid is for containing Heat Room, inside and outside big arch, port and combustion gas spout, flue, breastwork, forward and backward face wall, dog-hole, the double arched kiln stove of settling pond and feeding mouth.This alkali-resistant glass marble prescription is respectively filled a prescription summation above 100% under the situation of not considering loss on ignition, obviously unreasonable.In addition, two arch structures of this kiln and the no shrinkage cavity Corhart Zac-block of employing and high-quality silica brick are made the liner or the masonry of melting pool and two arch etc., have greatly improved cost with respect to traditional horse shoe flame kiln; Port is as mixing and the combustion zone in addition, can not emptying waste gas, and cause waste gas influence final product quality and reduction kiln work-ing life in the stove inner accumulated; And the generation of waste gas also can cause the generation of environmental pollution.
Summary of the invention
The present invention is intended to overcome above-mentioned technological deficiency, and a kind of production formula and production method thereof of alkali-resistant glass marble is provided, and the invention provides a kind of kiln that is used to make alkali-resistant glass marble simultaneously.The present invention has broken the theory that conventional water chestnut flame kiln can not be produced alkali-resistant glass marble, utilizes conventional glass sphere kiln, under the immovable situation of anti-material, and the production of the homogeneity by the control mixture, water ratio, realization alkali-resistant glass marble.Technology of the present invention is simple, and is easy to operate, and in conjunction with the automatic control means of science, operation control is easy, is beneficial to production and energy-conservation, constant product quality, and glass ball clarity height, quality is good, and raw material consumption is low, and environmental pollution is little.
