Description
The present invention is the heat insulating novel material that a kind of silicate starting materials Compound Machining that contains elements such as magnesium, aluminium, calcium, iron, sodium is made.
Particularly this material is a main raw material with a kind of lightweight non-metallic ore of domestic untapped utilization still, be equipped with other lagging material, subsidiary material, according to a certain percentage, carry out special working method and make, be widely used in the heat insulating of all facilities of departments such as chemical industry, oil, electric power, metallurgy, traffic, shipbuilding, automobile, building, light industry, national defence.
The coated use of this product or become the close mouth hole pattern shape structure that a kind of solid substrate of electrostatic connects behind the drying and moulding through cast has more obvious effect than existing lagging material.
Existing traditional mineral compound lagging material, as diatomite, asbestos products, vermiculite, glass, pearlstone, generally all single use, prescription can't not worked in coordination with to strengthen usefulness.Therefore, big with material volume, the thermal conductivity height adds the working procedure complexity, needs lashing, the time-consuming material that takes, currently available products aluminum silicate fiber, microporous calcium silicate, asbestos magnesiumcarbonate insulating powder; Wilkinite perlites etc., it is serious to add the man-hour dust, uses with the passing of time also easily powder of detached.
Now the performance with various heat preserving and insulating materials is compared as follows:

The wet processing schematic flow sheet of product of the present invention is seen Figure of description.
Lagging material of the present invention, 800 ℃ of high temperature of ability, thermal conductivity be 0.031 kilocalorie/meter, the time, degree; Unit weight 110kg/m
3, unit weight 900～1000kg/m when liquid
3, pH value＜8, water-fast, oil resistant, acid and alkali-resistance, performance is good.At normal temperatures, soak do not dissolve in 480 hours, indeformable, do not ftracture, do not burn, cohesive strength 0.25kg/cm
2, nontoxicity, no dust, free from environmental pollution, not etching apparatus, do not injure human body, under general condition use this product to need not lashing.Quality is soft certain elasticity, closed performance is good, 2/3 surface portion renewable repeated use of use and thermal insulation layer, end-use of the present invention is wide, be applicable to all hot equipment such as pipelines, stove, roof, the heat insulating on top layers such as roofing, special-shaped pipeline and the lock that can't construct to general lagging material especially, valve and spheroid, rotatoies etc. can use, and technology is simple when using, be easy to flaw detection in addition, accurately find the characteristics at equipment failure position in the thermal insulation layer, and can when hot equipment operation, can protect normally carrying out continuously and maintenance carrying out in proper order of production.And energy-saving effect is obvious, save energy reduces thermal losses exponentially, after testing proof, its heat insulation effect is under 600 ℃ of constant temperature situations, surface temperature is 93 ℃ during with material thickness 17mm during with material thickness 10mm, and surface temperature is 81 ℃, during with material thickness 44mm, surface temperature is 57 ℃, its economic thickness is 1/5th of traditional products such as asbestos, perlite, is 1/4th of microporous calcium silicate, 1/2nd of aluminum silicate fiber.
Embodiment: (calculating) with one ton of product
With the soft ore 30kg of special nonmetal picking removal of impurities, be ground into Powdered again with pulverizer.
With aluminum silicate fiber 10kg and asbestos 60kg with the removal of impurities of loosening of opener opener.
