Abstract
The invention relates to a ceramic foam glass product and manufacturing technology thereof, which are particularly used in industries such as wall body filling, building decoration, chemical industry, electric power and the like, play roles in sound absorption, heat preservation, thermal insulation and corrosion prevention, and belong to the technical field of foam glass products. The manufacturing technology mainly comprises the steps of: selecting cullet and/or flay ash and/or mineral slag as main raw materials (solid waste accounts for 80 to 95 percent of the total consumption of the raw materials); adding a small amount of non-metallic mineral and a foaming agent; adopting ceramic manufacturing technology, performing mixed crushing and dehydration molding; and cooling a sintered product to obtain a product, wherein the sintered product is prepared through the following steps that: during high-temperature glass melting, the foaming agent produces a large amount of bubbles, the bubbles are wrapped by high-viscosity glass solution, and closed pores are formed after the cooling to obtain the sintered product. The ceramic foam glass product and the manufacturing technology thereof have the advantages of simple and convenient manufacturing method, low energy consumption, and good performance of products with the density of between 0.2 and 0.8g/cm<3>, and the rupture strength of between 2 and 10Mp; and the product and the technology thereof integrate the advantages of ceramics and foam glass, have the characteristics of light mass, sound absorption, thermal insulation, corrosion prevention, high strength and the like, and are a great breakthrough of the field of the foam glass.
Description
Technical field
The present invention relates to a kind of foamed ceramic glasswork and manufacturing process thereof, specifically be used for industries such as body of wall filling, decorating building, chemical industry, electric power, play sound absorption, insulation, thermal insulation and preservative activity, belong to the foam glass product technical field.
Background technology
At present, the multicellular glass that is used for body of wall filling, decorative building material industry is main raw material with glass cullet normally, adds the material that whipping agent forms vesicular structure.It mainly acts on has been sound absorption and adiabatic.Need during multicellular glass is made in 750 ℃-900 ℃ fusing foaming of temperature, and then to anneal and form volume density be the 150-500kg/ cubic meter goods of folding strength 〉=0.6Mp.Because multicellular glass needs through foaming and anneals and burn till for twice, not only power consumption increases, and the product folding strength is little, and being used for building material industry has certain limitation.
Application number is that the Chinese invention patent of 03132276.x discloses a kind of lightweight, heat insulation, sound insulation environment-friendly ceramic goods and method of manufacturing technology thereof.The manufacture method of these light ceramics goods is with useless mud or abandoned mine slag and/or waste ceramic (glazing or not glazing), adds that the mixture of the former stone ore thing with expansion character and sintering properties-correcting agent stir; Broken again mixing and ball milling 16-24 hour, shaping and drying was through 1100 ℃ of-1250 ℃ of light ceramics goods that are fired into.Because light ceramics is a main raw material with useless mud etc., the firing temperature height increases power consumption equally.
For the pollution that reduces trade waste, noise pollution, water pollution etc., strengthen trade waste regeneration " with useless is treasured " set up the active demand that recycling economy is the China environmental protection Sustainable development.
Summary of the invention
Main purpose of the present invention is to overcome above-mentioned weak point, and providing a kind of is main raw material with glass cullet and/or flyash and/or slag and/or non-metallic minerals, adopts ceramic process, pulverize through mixing, and the dehydration moulding, sintering is cooled to goods.Technology is simple, product performance overcome multicellular glass intensity low and fire after need anneal to burn till for twice shortcoming, possess the multicellular glass light weight simultaneously, sound absorption, thermal insulation, the characteristic that does not absorb water.
Main solution of the present invention is achieved in that
Ceramic foam glass product formula rate of the present invention is the percentage ratio meter by weight: get glass cullet 50-80%, flyash 10-40%, slag 10-40%, non-metallic minerals 10-20%, whipping agent 0.2-5%; Above mixture is added water 60-100% ball milling, touch the dehydration moulding, or, be cooled to finished product through sintering with water extracter dehydration back extrusion molding with gypsum.
Glass cullet of the present invention are various waste plate glass, useless bottle glass;
Flyash of the present invention is waste coal ash, the waste coal slag after thermal power plant and/or the heat power plant's burning;
Slag of the present invention is waste residue and other solid waste of steelworks and/or iron work;
Non-metallic minerals of the present invention is silicon, aluminium mineral materials such as quartz, feldspar, talcum, porcelain stone, wollastonite;
Whipping agent of the present invention is rhombspar or carbon ink or silicon carbide or calcite;
Agglomerating plant of the present invention can be tunnel kiln, roller way kiln, rib formula kiln, porous ejection plate kiln.
Ceramic foam glass product manufacture method of the present invention adopts following processing step:
With glass cullet 50-80%, flyash 10-40%, slag 10-40%,, non-metallic minerals 10-20%, whipping agent 0.2-5% adds water ball milling 10-15 hour together of 60-100%, fineness reaches 250 mesh sieves and tails over less than 0.5%, through the dehydration moulding, burns till through the 750-1000 degree, firing time 4-6 hour, be cooled to product again.
Compared with the prior art the present invention has the following advantages:
The present invention adopts and introduce solid waste such as flyash and/or slag in the glass body is main raw material, solid waste accounts for the 80-95% of the total consumption of raw material, add a small amount of non-metallic minerals and whipping agent, when the high temp glass fusion, whipping agent produces a large amount of bubbles, bubble is wrapped up by full-bodied glass solution, and it is sintered products that the cooling back forms sealed porosity.The simple energy consumption of technology of the present invention is low, has overcome multicellular glass intensity and has been generally less than 1Mp in a lot of out of use shortcomings of occasion.Product performance reach density 0.2-0.8g/ cubic centimetre; Folding strength 2-10Mp is the breakthrough in multicellular glass field.
