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.
Model utility content
The technical problems to be solved in the utility model 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 utility model 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.
