Description
Technical field
The utility model belongs to technical field of buildings, more particularly to a kind of big composite evacuated insulation board of cavity.
Background technique
In modern architecture, at present using foamed plastics and light fibre material as heat-insulated (heat preservation) material, even if
It is heat-insulated (heat preservation) performance best foamed plastics and light fibre material, when its density is no more than 40Kg/m3, thermal coefficient
In the case of 0. 027W/m.K, with regard to very little a possibility that heat-insulated (heat preservation) performance to improve it again.Moreover use foam
Plastics and light fibre material, its unit materials consumption are bigger.
It using the method for vacuum heat-insulation (heat preservation), was proposed in 1893 by British scholar Dewar, it is empty with storage liquid is put
The low-temperature (low temperature) vessel of gas it is heat-insulated, to solve the problems, such as cryogenic refrigeration technique.Later in expeimental physics, the smelting of specific alloy
Refining, the sciemtifec and technical spheres such as aerospace industry and electronics industry, vacuum heat-insulation (heat preservation) technology are developed.Vacuum heat-insulation (is protected
Temperature) construction material production and application, at home and abroad still place is put the budding stage at present, and there are two main causes: 1. vacuum technologies
Technology, most of construction material production technicians and the technical staff's contact for being engaged in architectural engineering are seldom, therefore to its property
It can understanding deficiency；2. being thought as needing special, complicated, expensive system to realize to vacuum technology.In fact, vacuum heat-insulation
(heat preservation) is most promising method in building, and realizes its simple process, with foamed plastics or light fibre material
Expect that heat-insulated (heat preservation) compares, expense is not also high, or even also wants low.
Vacuum heat-insulation (heat preservation) is with following scheme under normal circumstances: 1. use the double wall of high vacuum；2. using Gao Zhen
Empty type chamber, type is intracavitary to have a certain number of intermediate polishing thin slices as radiation shield, it can good reflection light, to prevent heat
Amount radiation transmitting；3. have powdered substance perhaps this kind of powdered rubber of type chamber of light fibre or light fibre in vacuum
And have low heat conductivity under low temperature, type is intracavitary to be pumped into moderate vacuum (10-1-10-2Pa )。
Using perlite powder as filler, the shell of vacuum degree only heat-insulated (heat preservation) material of 10Pa, the heat-insulated of it (is protected
Temperature) performance than using foaming polystyrene heat-insulated (heat preservation) performance 24 times (compare from thermal coefficient: i.e. polystyrene is led
Hot coefficient is 0.027W/m. K, and crushed crude pearlite is 0. 001W/m.K).It is, in general, that the pearl powder in medium vacuum
Increase by 10 times than the performance that normal atmosphere is depressed with heat-insulated (heat preservation) performance.If comparing foamed plastic and crushed crude pearlite being filled out
Vacuum heat-insulation (heat preservation) material property filled, the unit consumption of material, cost etc. various factors, vacuum heat-insulation (heat preservation) plate
There is very big competitiveness.
