Abstract

The invention relates to a suction device for vacuum heat-insulating board. It comprises: a carrier, water-absorbing material and expansion resistance material which is mixed up to form a poromeric layer, separating material, air-breathing alloy and organic gas absorbing layer. The air-breathing alloy, organic gas absorbing layer and poromeric layer are arranged sequentially from inside to outside of the carrier, between the air-breathing alloy and organic gas absorbing layer equipped separating material. The invention is characterized in that: the top or bottom of the carrier is opening, the exposed surface area is increased and the rate of adsorption is improved correspondingly; the organic gas absorbing layer has a better ability of absorbing organic gas; doping expansion resistance material in the water absorbing material can limit the water absorbing material expanding and let air get through, it can ensure the efficiency of the super oxidation agent absorbing layer and gas absorbing material, and have the absorbing ability with air.

Description

technical field [0001] The invention relates to a vacuum suction device, in particular to a suction device for a vacuum heat insulation board which maintains the vacuum degree in the vacuum jacket of the heat insulation board. Background technique [0002] Due to its good thermal insulation and environmental performance, vacuum insulation panels have gradually been widely used in thermal insulation fields such as petroleum, chemical industry, construction, and refrigerators. However, the vacuum insulation panel tends to decrease the vacuum degree with the prolongation of time, which directly affects the thermal insulation performance of the vacuum insulation panel. The main reason is that the residual CO and CO in the jacket 2 , O 2 、H 2 、H 2 O or organic vapors, which are either released from the insulation material or the material used to make the insulation panel, or leak into the jacket through the welded area, in order to maintain the vacuum in the vacuum insulation ...
