Abstract
The present invention is the making process of heat insulating rainproof layer for various equipment. The making process includes mixing magnesium chloride with water and assistants, stirring to form solution while controlling to required temperature, mixing magnesium oxide with the solution to form paste, the combining with fiber fabric through painting or soaking in 50 min. The present invention is superior to available similar products.
Description
Technical field
The present invention relates to a kind of making that is incubated rainproof protective layer, it can be widely used in, and surface such as equipment or product needs the rainproof occasion of insulation in the every profession and trade, as fields such as cogeneration, petrochemical industry, light textile, metallurgy, medical treatment, food.
Background technology
The rainproof protective layer of present widely used insulation is galvanized sheet and aluminium alloy plate, and there is following shortcoming in actual use in these two kinds of rainproof protective layers: 1. have only rainproof effect, lack heat insulation function, it is a kind of fin; 2. be unable to undergo extruding and collision; 3. open-air cold and hot webmaster can't be managed, and is easily stolen; 4. not corrosion-resistant, can not renovate; 5. waste metals resources.
Summary of the invention
Technical problem to be solved by this invention be design a kind of can remedy existing rainproof protective layer be not incubated, perishable, wear out, be unable to undergo to push and the rainproof protective layer of insulation of defective such as collision.
It is that the solid magnesium chloride is mixed with water that the present invention addresses the above problem the technical scheme that is adopted, and adding auxiliary agent, stir, test to standard-required by cold kilsyth basalt, then magnesia is mixed stirring into pasty state again with the above-mentioned solution that has stirred, at last the above-mentioned material that has prepared is combined with fiber cloth within a certain period of time.
The material that has prepared of the present invention should combine with fiber cloth in 50 minutes, otherwise, surpass and can not use hardening time.
The material that has prepared of the present invention combines with fiber cloth, is meant the material that brushing has prepared on fiber cloth, or fiber cloth is immersed in the material that has prepared, forms product thus.
Auxiliary agent of the present invention comprises oxalic acid, ferrous sulfate or tertiary sodium phosphate.
Can also add diffusant and/or stearic acid and/or magnesium sulfate in the auxiliary agent of the present invention.
Fiber cloth of the present invention can be used multilayer, and it is selected according to different environment or temperature.
The present invention compared with prior art, have the following advantages and effect: 1. it adopts inorganic raw material to form, and is nonpoisonous and tasteless, sturdy and durable, the totally enclosed type insulation is rainproof, can be high temperature resistant 200 ℃ softening, not embrittlement, ability is frozen-30 ℃ and is not ruptured, non-scale, can in water, soak and not soften in 96 hours, not expand, can bear double centner pressure in the shell appearance.2. the surface is flushable, and fixedly inside thermal conservation material is not loosening, does not come off, and does not leak, and under equal environment, adopts the present invention, and surface temperature is lower 3-5 ℃ than aluminium alloy plate.3. do not need when constructing to shut down, particularly repair apparatus, flange, valve need only and just can recover former state in 2 hours.4. use on large-scale oxygen-eliminating device and oil tank heat insulation protecting layer, the advantage that seems is more outstanding, does not have interface and slit during application, is not afraid of violent storm and hail; Simultaneously, use in the open air not to be afraid of and stolen manageability.5. serial difficult problems such as the present invention makes in the heat insulating work that difficulty is big, weak effect, useful life are short are solved.

To combining of the said material that has prepared among above-mentioned all embodiment and fiber cloth, following two kinds of embodiments are arranged generally:
Embodiment 1:
Brushing method: it has two kinds of usings method, when using in construction comparatively easily during occasion, can with fiber cloth earlier volume (twining) to the heat-insulation layer of equipment that needs insulation (or cold insulation) or product, roll or hairbrush is directly brushed the last said material that has prepared in the foregoing description and got final product on fiber cloth with suede.
When using when difficulty of construction is more greatly or in complicated, different equipment or the pipeline, fiber cloth can be lain against on the ground, coat the said material that has prepared, carry out cutting according to the equipment of need insulation or the shape of product then, the fiber cloth that this is cut is compound to the heat-insulation layer of equipment or product (as pipeline) again.
Embodiment 2:
Infusion method: its is general uses in difficulty of construction more greatly or in complicated, the different equipment or pipeline.During use, the said material that has prepared is poured in the container of certain volume, fiber cloth is put into container soak certain hour (as 2 minutes), take out again and carry out cutting, compoundly get at last according to the equipment of need insulation or the shape of product.
It should be explicitly made clear at this point: during construction, the insulation surface of equipment or product should be smooth.The fiber cloth of selecting for use should be according to the thickness typing of heat insulation protecting layer; Indoor use, the thickness of protective layer can be 3 millimeters-3.5 millimeters, with No. 02 fiber cloth 4 floor; Outdoor application, when the pipe surface temperature below 20 ℃ the time, there is no need to do expansion joint Celsius, the thickness of protective layer can be 4 millimeters-4.5 millimeters, with No. 03 fiber cloth 5 floor; But make on high-temperature pipe, do the expansion joint of gauged distance according to the trend of pipeline, expansion joint wide can be 6 millimeters-8 millimeters of 200 millimeters, thickness, the interlayer material of turning in one's mind in expansion joint is wanted; Trench uses, and the thickness of protective layer can be 5 millimeters-5.5 millimeters, and is thick more certainly good more with No. 04 fiber cloth 5 floor, but thick more cost is high more.
