Abstract
A gas adsorbent used for the vacuum heat-insulating material to adsorb the residual gas and water in irreversible mode is a ZrVFe alloy instead of molecular sieve.
Description
What the present invention relates to is a kind of getter, is added on and is applied to the insulation aspect in the vacuum heat insulation material.This getter is that main alloy material is formed by the zirconium vanadium iron, is added on Irreversible Adsorption residual gas and moisture in the vacuum heat insulation material.This material can substitute fully or part substitutes used molecular sieve adsorbent.
In existing heat preserving and insulating material, getter mainly is to use molecular sieve, and it can reduce gas and moisture under the vacuum condition, and the heat preserving and insulating material thermal conductivity factor is descended.And the present invention to adopt the zirconium vanadium iron be that main alloying metal is compared effect of heat insulation with molecular sieve as getter as getter better raising is arranged.
What the present invention relates to is a kind of getter that vacuum heat insulation material is applied to the insulation aspect that is used for adding to.Be characterized in that at first this getter has adopted the alloy based on the zirconium vanadium iron, and carbon dioxide gas, oxygen, nitrogen, water vapour there is irreversible absorption, next be under high vacuum (the residual gas dividing potential drop is lower than 70 handkerchiefs) condition in vacuum heat insulation material addition seldom good effect is just arranged between 1%-10%.And can be owing to long-time the use causes that heat-insulating property descends.
One embodiment of the present of invention: add this getter of 1-10% in the vacuum insulation panel of nanometer new material technology Co., Ltd is thought to rub in Chengdu, thermal conductivity factor reaches＜0.01W/m.k.
Claims (6)
