Abstract
The invention relates to a method for producing glass-ceramics plate by using construction waste as main raw materials. The method is characterized in that: the construction waste and ingredients are uniformly mixed; the mixture is added to a glass melting furnace to be melted into glass melt; the melted glass melt is poured into water, and is transformed into glass particles through water quenching, followed by drying the glass particles through a dehydrator; the dried glass particles are subjected to a size classification through a vibrating screen; the glass particles are paved in a fire-proof die; the fire-proof die filled with the glass particles is conveyed in the furnace to carry out sintering and crystallization; finally, the sintered and crystallized plate material is subjected to burnish, polishing and cutting to obtain the finished product. With the present invention, the construction waste is adopted for producing the glass-ceramics plate, such that cost for the glass-ceramics is reduced, cycling utilization of the construction waste is realized, serviceable ranges of the raw materials of the glass-ceramics are widened, a new approach for digestion of the construction waste is provided.
Description
Technical field:
The present invention relates to a kind of manufacture method of crystallizing glass sheet material, particularly a kind of is the method that main raw material is made crystallizing glass sheet material with the building waste.
Background technology:
Along with the development of national economy, the raising of living standards of the people, the urban construction paces are accelerated, the city reorganization and expansion and remove all kinds of houses and spoir that the house decoraton finishing is produced, abandon material and other waste, building waste also increases year by year.According to measuring and calculating, building waste has accounted for more than 40% of municipal wastes total amount, and annual building waste total amount is at 800,000,000 tons.In order to digest these building wastes, realize that building waste handles innoxious, minimizing, resource utilization, improve the people's quality of life, be everybody common problem of paying close attention to.After deliberation, most building wastes all can utilize again, and their main component is silicate or aluminosilicate.
Devitrified glass is a kind of glass of tool specific composition, and a kind of polycrystalline material by crystallization control obtains has the intensity height, and good weatherability can substitute high-grade stone material as building and ornament materials.The raw material that present most devitrified glass production is mainly adopted is an industrial chemicals, and production cost is higher; In recent years also there are some to utilize mill tailings to make devitrified glass for raw material.We mainly are that raw material is made devitrified glass with the building waste, and the digestion building waste for building waste utilizes the new approach of looking for again, is realized made from construction refuse resource, and to solving municipal pollution, meaning is very big.
Summary of the invention:
Technical problem to be solved by this invention is to utilize building waste to produce crystallizing glass sheet material, reduces the cost of devitrified glass, realizes the recycle of building waste.Here the building waste of saying mainly is waste residue soil, queen closer, broken ceramics, glass cullet and concrete waste material etc., mainly is meant ceramic, does not promptly comprise plastics, paper wood, timber and steel etc.Be main raw material with the building waste again, be equipped with batchings such as quartz, feldspar, calcite, zinc oxide, barium carbonate, soda ash and borax, be made into the raw material of making glass.
By analysis, in described building waste, the shared mass fraction of each chemical ingredients is:
SiO2 60.65～61.42 Al2O3 17.41～14.86 Fe2O3 7.78～3.71CaO?3.82～11.58 MgO 2.16～3.03 K2O?5.37～2.71 Na2O 0.71～1.74MnO?0.12～0.07 TiO2 0.01～0.57 SO3 0.01～0.29 P2O5 0.13～0.02。
Through test, the mass fraction scope of making the proportioning raw materials of crystallizing glass sheet material is:
20～50 parts of building wastes; Quartzy 20～30 parts; 0～20 part of feldspar; 5～20 parts in calcite; 1～6 part in zinc oxide; 1～7 part of barium carbonate; 1～10 part of soda ash; 0～5 part of borax; 0.2～3 part of tinting material.
Building waste best in quality amount ranges is between 30～46 parts.
Utilize building waste to produce the method for the method of crystallizing glass sheet material, its technical process is as follows:
At first building waste is done pre-treatment, detect culled wood in the building waste, waste paper sheet, plastic waste, scrap metal etc., with construction waste crushing to granularity 50～70 orders, the granularity of other raw materials also is crushed to 50～70 orders, building waste and above-mentioned various raw material in proportion batch mixes evenly after, join in the glass melting kiln, it is fused into glass metal, 1480～1560 ℃ of temperature of fusion.The glass metal that fusing is good flow into water temperature less than in 45 ℃ the water, and glass metal is become the glass grain of certain particle size size by shrend, and diameter is usually at 0.3～3 millimeter.The glass pellet is pulled out from water, the glass pellet is dried with dryer.Adopt vibratory screening apparatus that the glass pellet is carried out size classification; Glass particle is tiled in bottom in the fireproof die less than 1.5 millimeters fines, and particle is layered on the surface as lining greater than a glass material of 1.5 millimeters; The aluminum oxide powder of shop one deck 1 mm thick is as releasing agent between fireproof die and glass pellet, and it is bonding to prevent that glass particle and fireproof die from taking place.Charged mould is sent to carries out the sintering crystallization in the kiln, 1080～1150 ℃ of crystallization temperatures.The sheet material that the sintering crystallization is good becomes finished product after polishing, polish, cutting.
The present invention is aided with other raw material production crystallizing glass sheet materials with the main raw material of building waste as crystallizing glass sheet material, has widened the use range of devitrified glass raw material, for digestion building waste waste material has been opened up a new approach.With the building waste is raw material, can grey, the dark crystallizing glass sheet material of producing such as black.
