Abstract
The invention relates to a method for producing foam glass by use of glass fiber waste, which comprises the following steps of firstly sorting the glass fiber waste, removing impurities and breaking into fine particles; uniformly mixing the raw materials according to the weight percentage in the raw material formula, and performing ball milling to obtain fine powder below 200 meshes; then putting the fine powder into a heat-resistant steel mould box, and performing preheating, foaming, foam stabilization, setting, demoulding, annealing and cooling to obtain a foam glass blank; finally, cutting the blank into a finished product. According to the method provided by the invention, a great quantity of waste raw materials generated by industrial production are made fully used, the production cost is low, the process is simple and easy to implement, the foaming time is short while the foaming is uniform, the energy consumption is remarkably reduced, and the product quality is stable.
Description
Technical field
The present invention relates to a kind of method of utilizing glass waste material to manufacture multicellular glass.
Background technology
Multicellular glass is that nineteen thirty-five is first by the invention of French St.Gobain company, it is by glass cullet, whipping agent, additive and promotor etc., be mixed to form compound through grinding, and be put in specific mould, the porous glass material of making through techniques such as preheating, sintering, foaming, annealing.
The raw material that existing foamed glass foaming adopts is conventionally cullet, lava and flyash etc., is mainly manifested in raw materials cost higher.
Glass waste material is the tankage that produce in glass production process, and recovery utilization rate is extremely low.
Summary of the invention
The present invention is directed to prior art deficiency, a kind of method of utilizing glass waste material to manufacture multicellular glass is provided, utilize glass waste material to manufacture multicellular glass, raw materials cost is low.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of method of utilizing glass waste material to manufacture multicellular glass, comprises the following steps: 1) glass waste material is sorted to processing, remove impurity, be broken into fine particle; 2) composition of raw materials by weight percentage, be discarded glass particle by 50～60% glass waste material particle, 1～2% whipping agent, 2～3% stablizer, 3～5% fusing assistant, 0.5～1% properties-correcting agent, 0.5～1% promotor, remainder, above-mentioned raw materials mixed to ball milling and make the following fine powder of 200 order; 3) pack described fine powder into high temperature steel diaphragm capsule, through preheating, foaming, steady bubble, sizing, the demoulding, annealing, the cooling foamed glass blank that makes; 4) blank is cut into finished product.
In technique scheme, described whipping agent is pure carbon, silicon carbide, carbon black, dolomite powder, phlogopite, Manganse Dioxide, water glass, saltcake, carbonate, silicates, Sulfates.
In technique scheme, described stablizer is Sodium hexametaphosphate 99, boric acid, ferric oxide, sodium phosphate, ferric oxide, borax, trisodium phosphate, sodium sulfate.

The present invention compared with prior art, has following beneficial effect: the present invention makes full use of a large amount of waste and old raw material that industrial production produces, and production cost is low, and technique is simple and easy to realize, and the short and uniform in foaming of foamed time, significantly reduces energy consumption, and constant product quality.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail: a kind of method of utilizing glass waste material to manufacture multicellular glass, comprises the following steps: 1) glass waste material is sorted to processing, remove impurity, be broken into fine particle;
2) composition of raw materials by weight percentage, be discarded glass particle by 50～60% glass waste material particle, 1～2% whipping agent, 2～3% stablizer, 3～5% fusing assistant, 0.5～1% properties-correcting agent, 0.5～1% promotor, remainder, above-mentioned raw materials mixed to ball milling and make the following fine powder of 200 order; 3) pack described fine powder into high temperature steel diaphragm capsule, through preheating, foaming, steady bubble, sizing, the demoulding, annealing, the cooling foamed glass blank that makes; 4) blank is cut into finished product.
Described whipping agent is pure carbon, silicon carbide, carbon black, dolomite powder, phlogopite, Manganse Dioxide, water glass, saltcake, carbonate, silicates, Sulfates.
Described stablizer is Sodium hexametaphosphate 99, boric acid, ferric oxide, sodium phosphate, ferric oxide, borax, trisodium phosphate, sodium sulfate.
Described fusing assistant is sodium carbonate, Buddhist water glass, SODIUMNITRATE, ethylenediamine salt, borax.
Described properties-correcting agent is weisspiessglanz, anhydrous sodium sulphate.
Described promotor is sodium sulfate, calcium carbonate, barium sulfate, aluminium sesquioxide, boron trioxide, antimonous oxide, white arsenic, Vanadium Pentoxide in FLAKES, Manganse Dioxide, manganic oxide.
Whole foaming process approximately needs 70～110 minutes, first compound is packed into diaphragm capsule compacting and send into foaming furnace, that (350～400 DEG C of left and right) carries out preheating below the oxygenolysis temperature of carbon, then as soon as possible mixed material heating is arrived to sintering temperature (approximately 680～700 DEG C), make compound obtain abundant sintering post-foaming, then be slowly heated to blowing temperature and keep for some time surely to steep, finally make DEG C left and right sizing of glass Slow cooling to 600, after the demoulding, send into annealing furnace annealing, when the demoulding, foam blank surface temperature is sharply cooling and inner still in the condition of high temperature, so should have an equal thermal process before entering annealing operation, at the import position of annealing furnace constant temperature, then just enter the Xu Leng stage, anneal cooling with the constant speed of cardinal principle, for the later temperature control of the strain point that is cooled to exceed glass be quenched to after the temperature (200 DEG C following) that temporary stress is increased, become foamed glass blank, whole annealing time is 24～30 hours.
The present invention utilizes glass waste material as main raw material, then adds other auxiliary material and manufacture high-quality multicellular glass, and raw materials cost is low.Glass waste material is to produce and reach a large amount of waste products, substandard products, tankage in glass production process.Manufacturing process is first glass waste material to be broken into particle, then mixes ball milling with other batching, and various raw materials mix, uniform in foaming, and yield rate is high.If first by remix after all raw material ball millings, can cause mixing inhomogeneous, foam inhomogeneous.
