Abstract

The fire resistant high strength and high density calcium silicate plate is produced with crystalline silicate powder, amorphous silicate powder, calcareous material, mineral additive and fiber material and through the processes of mixing, pressing or casting to form, steam curing in saturated water vapor at 190-200 deg.c inside a steam curing kettle for 6-20 hr, and stoving in hot blast at 100-180 deg.c to water content below 5% to obtain the product of density 500-1000 Kg/cu m. It may be used as heat insualting fireproof material in non-ferrous metallurgy and other fields.

Description

The method for making of high temperature resistant, high strength and high density calcium silicate plate
(1) technical field: the present invention relates to a kind of method for making of high temperature resistant, high strength and high density calcium silicate plate, belong to Industrial buildings material and heat preserving and insulating material technical field.
(2) background technology: in the nonferrous metallurgy industry, subcontract in the molten aluminum liquid, material flowing nozzle liner refractory materials such as siliceous, magnesia commonly used, though these refractory materials heat resistances are good, intensity is also high, but material itself has certain wetting property with aluminium liquid, cause foreign matter content height in the moulding aluminium, quality descends, and a kind ofly is used for molten aluminum liquid with the nonwettable material of molten aluminum liquid and subcontracts and the material flowing nozzle inner lining material if choose.Can overcome this shortcoming.
Consider firmly that for safety generally select resistant to elevated temperatures steel alloy to do a suspender material, from whole pipeline, thermosteresis is very big, and all uses resistant to elevated temperatures steel alloy in the past aspect the hanging of heat power equipment and pipeline, cost is also high.
If calcium silicate material is used for above two industrial circles, can solve the problem of present existence, but about about 200 kilograms every cubic metre of present calcium silicate material density, intensity is lower, and folding strength has only about 0.3MPa, and ultimate compression strength has only about 0.5MPa, if be used for above-mentioned two aspects, must improve prescription and technology at the problems referred to above, invent a kind of calcium silicate material of high temperature resistant, high strength and high density degree.
(3) summary of the invention:
Purpose of the present invention is exactly at the needs in the above-mentioned industrial circle, a kind of calcium silicate material of high temperature resistant, high strength and high density degree is provided, the present invention applied on July 3rd, 1998 with the applicant, name is called " a kind of manufacture method of calcium silicate thermal insulation fireproof material ", the patent No. is that 98102760.7 static steam-cured method is the basis, improves prescription and technology.Now details are as follows with method steps of the present invention:
1 raw material is prepared:
1.1 silicon metal micro mist: as various quartz micropowders.
1.2 non-crystalline silicon micro mist: as silicon ash, rice hull ash, white carbon black.
1.3 calcareous raw material: as unslaked lime, slaked lime, calcium carbide mud.
1.4 mineral add material: as wollastonite powder, expanded vermiculite, mica.
1.5 filamentary material: as glass fibre, ceramic fiber, natural organic fiber is as fiber crops, cotton, bamboo, vegetation fiber.
2 method for makings
Clear up and be milk of lime 2.1 calcareous raw material is added water, also can directly use slaked lime powder
2.2 the mixture of silicon metal micro mist or non-crystalline silicon micro mist or two or more micro mists mixes with milk of lime or slaked lime powder, blending ratio is CaO: SiO 2(mol ratio)=0.95～1.05.
2.3 will add 1～8% filamentary material in 2.2 compounds, 0～12% mineral add material, fiber can be one or more the combination in 1.5, and it can be one or more combination in 1.4 that mineral add material.
2.4 above-mentioned compound is pressed into sheet material on the band moulding press, also pourable in removable mould.
2.5 send 2.4 sheet materials or band mould mould material to steam-cured still, under 190 ℃～200 ℃ saturated vapor conditions steam-cured 6～20 hours.Naturally cooling afterwards.To the block of band mould, need form removal.
2.6 steam-cured back goods are dried in 100 ℃～180 ℃ hot blast to moisture below 5%.
2.7 the oven dry goods are product after grinding on request and cutting.
The material that adopts the inventive method to make is density 500～1000kg/m 3Sheet material or block, as subcontract in the nonferrous metallurgy, material flowing nozzle liner or purposes such as support heat insulation loop or other heat insulating fire prevention.
Advantage of the present invention is the starting material wide material sources, and is cheap, and technological process is simple, and product performance are good.
