Technical field
The present invention relates to new material technology-inorganic non-metallic (high temperature insulating) field of material technology, refer to a kind of vacuum structure high temperature insulating plate and preparation method thereof especially.
Background technique
Energy-saving and emission-reduction are China's fundamental state policies.The output of China's iron and steel, cement, petrochemical industry, the highly energy-consuming trade such as coloured is in the first in the world for years, 71.1% is weighed in industrial energy specific consumption in 2010 in energy consumption structure, wherein the specific consumption of the high energy-consuming industry energy weighs 81.2%, has accounted for the overwhelming majority of industrial trade energy consumption.Current, although China is using the strategic task of industry restructuring as sustainable development, change because essence can not occur the following 20 years industrial structures of China based on industry, in energy consumption structure, industrial energy consumption will occupy comparatively great share.Thus when the in short supply and imbalance between supply and demand of energy resources intensifies at home, except adjustment China industrial structure change, industrial energy saving particularly the energy-conservation of high energy-consuming industry has important strategic importance to the energy problem in solution industry and even the whole national economic development, and the successful implementation of energy-saving and emission-reduction work to China's energy-saving strategy promoting highly energy-consuming trade is significant.
Iron and steel, cement and petrochemical industry energy consumption occupy 35% of national energy consumption, and in industrial energy consumption, accounting is more up to more than 50%.Country's relevant policies explicitly called for: by 2015, and industrial boiler, kiln average operating efficiency improved 5 and 2 percentage points than 2010 respectively, formed the energy saving capability of 7,500 ten thousand tons of standard coals " 12 " period.The standby observable index of the high-temperature hot frocks such as industrial boiler (kiln) is great, except realizing except energy-conservation taping the latent power by advanced technologies such as self equipment upgrading, product restructuring, process optimizations, heating technology, thermal insulation technology lifting etc. also will improve energy efficiency and manufacturing efficiency greatly.Therefore, research and development new type high temperature thermal-protective material, further energy efficient, significant for high-energy equipment efficiency utilization such as industrial boilers (kiln), also meet national energy-saving and reduce discharging sustainable development target.
Thermal-protective material traditional at present has the light-weight brick (block) of silicious marl, perlite, calcium silicate, clayey, High-Alumina, mullite, corundum, all kinds of material such as siliceous, magnesia, the aglite of the various refractory fibers (felt, block, plate) such as common aluminosilicate property, High-Alumina, mullite, aluminum oxide and all kinds of material, they are for the insulation of each Industrial Stoves, and energy-saving effect is remarkable.
Light-weight brick (block) production technology of all kinds of material such as clayey, High-Alumina, mullite, corundum mostly adopts foam method, poly-light method or adds the explained hereafter such as inflammable matter method, lightweight base substrate is after high-temperature calcination, size is on demand cut again, and (or mill) is product, which produces a large amount of lightweight corner aggregates or powder.Meltblown method can prepare alumina hollow ball, more repressed adobe is burnt till as light-weight brick can use through high temperature, complex process.
The heat-insulation light material produced by above method, can not shaping large and thin thermal baffle, can not make full use of the powder after cutting, and compared with vacuum insulation panel, thermal conductivity is higher.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of vacuum structure high temperature insulating plate, comprise heat insulation bulk material and skin, wherein, heat insulation bulk material inner vacuum, vacuum between heat insulation bulk material and skin, heat insulation bulk material is cuboid tabular or bulk, and skin fits tightly on heat insulation bulk material.
Heat insulation bulk material is that one or both compactings in various fire-resistant light powder material, fire-resistant light granules material form.Fire-resistant light powder material, fire-resistant light granules material are one or more in silicious marl, perlite, calcium silicate, clay, high alumina, mullite, corundum, all kinds of refractory raw material material such as siliceous, magnesia, fire-resistant light powder material granularity is 0-0.5mm, and fire-resistant light granules material granularity is 0-10mm.
Skin is the one in aluminium foil bag, Copper Foil bag, plastic bag, and outer layer thickness is 0.05-0.35mm.
The preparation method of this vacuum insulation panel is as follows:
Fire-resistant light powder material, fire-resistant light granules material or the mixture of the two are loaded in skin, compressing or offhand, with vacuum pump evacuation, after pumpdown time is 0-99 second, deflation time 2-5 second, electric heating member heating sealing part, to high temperature 300-500 DEG C, seals time 0-9.9 second, finally completes encapsulation.
Wherein, fire-resistant light granules material carried out friction shaping before loading skin, for the particle having corner angle, according to the hardness of different materials, in cylinder, rotated 5-60 minute, and particle, without after obvious corner angle, loads in skin shaping.For spherical particle, directly load in skin shaping.
The beneficial effect of technique scheme of the present invention is as follows:
(1) usage mode is flexibly with various.This thermal baffle (block) can be used for one end of refractory brick non-working surface for insulation, also can clog in the hollow structure of refractory brick and be incubated, or directly pastes the insulation of Industrial Stoves liner.
(2) make simply, heat preservation and energy conservation effects is good.Thermal baffle (block) for vacuum structure is lower with the lightweight material thermal conductivity of proportion than antivacuum same material, and heat preservation and energy conservation effects is good, particularly directly uses after exhaust heat encapsulation, burns till, energy saving without the need to high temperature, simple and convenient.
(3) bulk material wide material sources.The bulk material of vacuum insulation panel not only takes from fire-resistant light powder (particle) material of clayey, High-Alumina, mullite, corundum, all kinds of material such as siliceous, magnesia, the lightweight corner aggregate also produced during desirable production all kinds of light-weight brick (block) certainly or powder, the dead meals such as the drift pearl also in desirable fly ash in electric power plant freely, energy-saving and emission-reduction, environmental protection.
