Abstract
A kind of novel method with albite actinolite schist production rock wool because the speed of utilizing host albite, Tremoliteor Tremoliteasbestos in the raw material to be had is melted, energy conservation characteristic, can reach the purpose that cuts down the consumption of energy in (fusion) process of production.Simultaneously, the molten slurry of this kind raw material also has good fluidity, characteristics that total alkali is low.Remove and be convenient to melting operation, reduce outside the production fault, also help the physicochemical property that improves product.Use raw material of the present invention and prescription, can easily obtain acidity quotient about 2.0, total alkali (calculating by weight) is lower than 3.0% high-quality rock wool.Energy-conservation more than 8% in (fusion) process of production.
Description
Rock wool (mineral wool) is a kind of mineral fibre, is widely used in building, the insulation of thermal technology's industry do, soundproof material.
At present, producing rock wool both at home and abroad, all to use basalt (or diabase) class be main raw material, is equipped with auxiliary materials such as limestone, dolomite, becomes fine through technologies such as fusion, winding-up or wire drawings.A kind of technical process of adopting centrifugal injection method to produce rock wool, show as accompanying drawing, with main raw material (1), auxiliary material (2), coke (3), respectively broken (4) And prepare burden by a certain percentage (5), again by cupola furnace fusion (6), molten slurry forms the rock wool staple fibre through four roller whizzers and the centrifugal winding-up of high pressure draft (7), at last by reel (8), packing (9), warehouse-in (10).Through the rock wool staple fibre that centrifugal winding-up forms, before reel, can make various asbestos products, as rock cotton board, pipe, cover, felt etc. by already known processes.
In U.S. Patent No. 3557575, once various basalt raw materials had been carried out discussing widely.
The present invention is a kind of rock wool that produces with new raw material, and the speed that it is characterized in that utilizing host albite, Tremoliteor Tremoliteasbestos in the raw material to be had is melted, energy conservation characteristic, reaches the purpose that cuts down the consumption of energy in (fusion) process of production.Simultaneously, the molten slurry of this kind raw material has also that viscosity is low, the characteristics of good fluidity, removes and is convenient to melting operation, reduces beyond the fault in fusing, the pulling process, also helps the physicochemical property that improves product, is particularly conducive to and adopts fiber elongation method to produce macrofiber.
The main raw material that the present invention uses is a kind of metamorphosed rock, and the rock name is called albite actinolite schist (or Tremoliteor Tremoliteasbestos albite schist), and its mineral composition is (a percentage ratio meter by volume): albite 40-55%; Tremoliteor Tremoliteasbestos 45-65%; Pistacite, chlorite 5-10%, widely used basalt (or diabase) class was diverse during it was produced with present rock wool, the latter belongs to the magmatite class, its essential mineral consists of plagioclase, pyroxene, bar hurdle stone etc., formation temperature is more than 1000 ℃, and the albite actinolite schist belongs to low temperature greenschist facies metamorphism rock, is formed in 500 ℃ of following temperature environments.This has just guaranteed that this rocks of fusion is more much lower than molten basalt, the needed temperature of diabase class magmatite.
Albite actinolite schist used in the present invention, its Chemical Composition scope are (percentage ratio meter by weight):
Silicon-dioxide 45-50% aluminium sesquioxide 13-17% ferric oxide 2-6%
Iron protoxide 7-10% calcium oxide 8-12% magnesium oxide 7-10%
Potassium oxide 0.1-0.3% sodium oxide 1.5-3.0% titanium dioxide 1-3%
Add any of dolomite or limestone as auxiliary material (being no more than 25% by weight), except that adjusting material property, double as flux.Improve magnesian content, can make product have acid-and base-resisting performance preferably.
According to No. 124449, English Patent: can before the furnace charge fusion, add any (being no more than 5-10% by weight) in the oxide compounds such as titanium oxide, aluminum oxide, zinc oxide, thereby improve the alkali resistance of product greatly.
Use raw material of the present invention and prescription, the pilot-plant test that carries out on Xi'an rock wool factory existing installation has been obtained success.
The dolomite of albite actinolite schist 25% example 1: with 75%(by weight), fusion under 1320-1350 ℃ of temperature jets fine (model TG-1) through centrifugal.
The Chemical Composition of TG-1 rock wool following (percentage ratio meter by weight):
Silicon-dioxide 43.76% aluminium sesquioxide 13.13% ferric oxide 1.69%
Iron protoxide 7.90% calcium oxide 19.78% magnesium oxide 10.83%
Potassium oxide 0.50% sodium oxide 1.74% titanium dioxide 1.26%
The acidity quotient MK=1.86 of product
Example 2: by weight) albite actinolite schist with 80%(, 20% dolomite, fusion under 1350 ℃ of temperature jets fine (model TG-4) through centrifugal.
The Chemical Composition of TG-4 rock wool following (percentage ratio meter by weight):
Silicon-dioxide 44.05% aluminium sesquioxide 13.18% ferric oxide 2.08%
Iron protoxide 8.01% calcium oxide 17.24% magnesium oxide 11.24%
Potassium oxide 0.50% sodium oxide 2.24% titanium dioxide 1.32%
The acidity quotient MK=2.01 of product
Example 3: by weight) albite actinolite schist with 80%(, 20% limestone, fusion under 1300-1320 ℃ of temperature jets fine (model TG-3) through centrifugal.
The Chemical Composition of TG-3 rock wool following (percentage ratio meter by weight):
Silicon-dioxide 44.97% aluminium sesquioxide 13.24% ferric oxide 1.79%
Iron protoxide 8.01% calcium oxide 21.80% magnesium oxide 6.85%
Potassium oxide 0.37% sodium oxide 1.96% titanium dioxide 1.30%
The acidity quotient MK=2.03 of product
In with above-mentioned three prescription production processes, suitable when going out cotton rate and using basalt, fusion temperature reduces 50-80 ℃ than doing with basalt when main material is produced, coke consumption reduces 8-9%, power consumption reduces 5-7%, in above-mentioned three examples, use the albite actinolite schist to compare with using basalt, have the effect that fusion temperature is low, melt even, the molten slurry good fluidity of material. When using basalt (or diabase) class to produce rock wool as main material, add (by weight) albite actinolite schist more than 40%, also can play the effect that reduces simultaneously melt temperature and molten slurry viscosity, receive the effect that cuts down the consumption of energy.
