Abstract
The invention provides a kind of novel nano micro-crystal plate production system, including raw material system, melting furnaces, tri-roll press machine, crystallization kiln, product postorder processing system.Melting furnaces using unit kiln and using all-oxygen combustion new technology, with pure oxygen combustion-supporting, it is small to avoid glass pollution, environmental pollution caused by burning, the composition of glass is stable, performance indications are high, melting rate is high, energy-saving effect is obvious, improve the service life length of tank furnace, longitudinal temperature in melting tank is easily controllable, and defect is founded in reduction.Cost of putting up a kiln reduces by 45% or so than the tank furnace with regenerator.Furnace pressure, temperature can automatically control, and melting furnaces set industrial tv monitoring system, monitor operating mode and the situation that feeds intake in kiln.System uses tri-roll press machine, and pressing result is good, and Yield and quality is high.The nano microcrystalline plate that the production system of the present invention obtains, absorb water almost nil, the remote super large reason stone of compression strength, bending strength, Mohs' hardness, acid resistance, alkali resistance, surface gloss and granite product.
Description
Technical field
The invention belongs to building materials field, more particularly to a kind of novel nano micro-crystal plate production system.
Background technology
Nano microcrystalline plate, it is that a kind of formula of specific composition controls material internal nucleus nano microcrystalline by temperature schedule
Process and formed there is excellent physical and chemical performance, the composite that is made up of crystal and solid solution, its Mohs' hardness is 5.5 ~
8, compression strength is 360 ~ 680MPa, and rupture strength is 30 ~ 70MPa, and impact strength is 2.0 ~ 4.8 kg/cm2, light
Damp degree is 90 ~ 110 gloss units, and the coefficient of expansion is (1~80) × 10-7/ °C, water absorption rate ＜ 0.05%, have good
Acid-proof alkaline and excellent thermal shock resistance, at a temperature of 500 °C, be directly placed into water or will not be burst in air, it is overall
It is excellent.Furnace panel, building and ornament materials, deck plate, wear-resisting acid and alkali-resistance casting, seal etc. are widely used as, it is polished
Rear nano microcrystalline plate surface stain resistance is strong, acid and alkali-resistance, it is wear-resistant, do not fade, be corrosion-resistant, be safe and environment-friendly, be hygienic, be self-cleaning
It is beautiful Deng premium properties, elegant, gloss, it is bound to make nano microcrystalline plate to turn into ceramic veneer of new generation, ceramic paster
Optimal substitute products, and can be widely applied to furnace panel series, such as electromagnetic oven panel, kitchen tools panel, stove panel in household electrical appliances
Deng.
In Europe, the United States, Russia, day country, the research starting of micro-crystal board material is more early, and micro-crystal board material the seventies come into vogue, mesh
Preceding only a small number of industry more advanced the country such as U.S., the former Soviet Union and day instinct tissue industrialized production, they are with purifying
Learn raw material SiO2, Al2O3, CaO etc. to be formulated, its production method mainly there are two kinds, and one kind is rolling process, first by micro-crystal plate
Material raw material mechanical pressing, then carries out crystallization again；Another kind is water quenching, first by micro-crystal board material melting sources into glass slag charge,
Mechanical pressing or utilization saggar are molded again, finally carry out crystallization.It is mainly former with other glass using slag in initial period, product
After expecting mixed melting, flat board sintered glass ceramics is made using rolling process technique productions, then after rubbing down, with beautiful decorative pattern
Sheet material, for building decoration.
Nano microcrystalline sheet material uses the production technology of cleaning, does not produce pollutant in production process, firing temperature is low, energy consumption
Low, production efficiency is high, and can turn waste into wealth largely by the use of the broken waste material of mineral products as raw material needed for production, save natural resources, phase
Believe that nano microcrystalline plate will can be extensive with the ecological, environmental protective theory of its unique superior physicochemical property and " safe and healthy, hygienic "
Applied to various aspects in people's daily life.
Rolling process produces nano microcrystalline sheet material, is not suitable for founding infusibility and quality using heat accumulating type End Port Glass Tank Furnace more
It is required that high glass.Combustion system uses air-breathing, glass can be polluted, the volatile quantity of alkali metal is big, caused cigarette
It is large-minded, it is unfavorable for environmental protection；It is relatively low that it is melt into rate, 65% or so, is extremely difficult in full kiln in longitudinal temperature distribution and stove
Atmosphere meets glass melting and the requirement of clarification.
The content of the invention
In order to improve the problem of existing micro-crystal plate production technology is present, the present invention proposes a kind of novel nano micro-crystal plate life
Production system.
A kind of novel nano micro-crystal plate production system, it is characterised in that including raw material system, melting furnaces, tri-roll press machine, crystalline substance
Change kiln, product postorder processing system, the raw material system and the melting furnaces, the melting furnaces and the calender, the calender
With the crystallization kiln, the crystallization kiln and the finished product postorder processing system, connected by induction system；The raw material system
Including raw material workshop, hybrid system is weighed, raw materials melt is glass metal by the melting furnaces, using unit kiln, including feed bin, is located at
Batch charger, filling pocket below the feed bin, the first combustion system positioned at the melting furnaces two side, under the batch charger
The melting tank of side and depositing reservoir, cooling end with agitating device, first combustion system are positioned at the melting furnaces two side
A pair of burners, combustor sidewalls are passed through fuel combustion using the injection of some total oxygen rifles pure oxygen, front, and the cooling end includes
Cooling system, the image-type liquid level meter with batch charger interlocking, the control system include temperature control module, industrial TV monitoring
Module, furnace pressure automatic control module, liquid level automatic control module, pure oxygen pipeline control module, the temperature control module connection is positioned at described
