Abstract
The invention discloses a method for testing an air leakage position of a vacuum insulated panel. The method comprises the following steps: wholly spraying penetration liquid on two sides of the vacuum insulated panel, so that the penetration liquid is totally dispersed on a surface film layer; spraying the penetration liquid on the side, so that the penetration liquid totally covers the interior of hot-seal sides at the periphery of the vacuum insulated panel; naturally airing the sprayed vacuum insulated panel in a shady, cool and ventilated place for certain time, cutting off a packaging film of the vacuum insulated panel, and observing a position where the color of a core material changes; if the impregnation occurs on an inner core material, air leakage occurs on a film at the corresponding position; if the impregnation occurs at the edges of the hot-seal sides of the periphery, air leakage occurs at a hot-seal part at the corresponding position. According to the method, the specific air leakage position on the film can be detected, the operation process is simple, the practicality is high, and any part with fine air leakage can be found.
Description
Technical field
The invention belongs to the detection method of building thermal insulation material, specifically relate to a kind of method of checking vacuum heat-insulating plate Gas leak position.
Background technology
Vacuum heat-insulating plate is that to take ultra-fine fibre glass etc. be core material, usings plastic-aluminum combined film as packaging bag, the high-efficiency insulated sheet material obtaining after Vacuum Package.Manufacture good evacuated panel, its coefficient of heat conductivity only has 0.004 W/ (mk), compares with conventional insulation material, and vacuum heat-insulating plate has extremely excellent heat-insulating property.Between its inner condition of high vacuum degree, once gas leakage, the heat-insulating property of the monoblock heat-insulating shield even complete failure of having a greatly reduced quality.Therefore, the long-term vacuum of assurance vacuum heat-insulating plate is air tight seems particularly important.
The gas leakage of vacuum heat-insulating plate is mainly divided into two kinds of situations: due to the wearing and tearing of breaking the long-term chronic gas leakage causing and the edge sealing gas leakage causing because the heat-sealing of hot edge seal place is uneven of vacuum laminated film.The detection method of vacuum heat-insulating plate Gas leak position is now disclosed is only minority.If adopt seal detector to the vacuum heat-insulating plate check of leaking gas, process is loaded down with trivial details, and can not find the position of concrete gas leakage, also likely in operating process, destroyed the position of gas leakage, make to be in Gas leak position the processes such as production technology, transportation, use and improve and remedy, can not be from truly carrying out perfect to its structure and performance.
Summary of the invention
Object of the present invention is intended to overcome the deficiency in prior art, and the method for direct, the easy detection vacuum heat-insulating plate of a kind of energy Gas leak position is provided, and finds the directly position of gas leakage of hot edge seal or core surface.
For realizing the technical scheme of object employing of the present invention, be: a kind of method of checking vacuum heat-insulating plate Gas leak position is provided, has it is characterized in that comprising the operation steps of following order:
(1) at the saturating liquid of the equal whole spraying soaking in the two sides of vacuum heat-insulating plate, make to soak into liquid and be all scattered in surface film layer;
(2) side spray is soaked into liquid, makes to soak into liquid and is all covered in vacuum heat-insulating plate surrounding hot edge seal inside;
(3) vacuum heat-insulating plate after spraying is placed on to cool place, ventilation natural air drying certain hour;
(4) above-mentioned vacuum heat-insulating plate encapsulating film is cut off, observed the position that core becomes color;
(5) according to soaking into immersion stain judgement Gas leak position: if flood on inner core, the film that can be judged as relevant position leaks air; If dipping is on surrounding hot edge seal edge, heat-sealing place that can be judged as relevant position leaks air.
Method of the present invention, is characterized in that the liquid color of soaking in described step (1) is different from the color of the inner core of vacuum heat-insulating plate for any one.
Method of the present invention, is characterized in that the certain hour in described step (3) is 20 ~ 48 hours.
Compared with prior art, advantage of the present invention and good effect are:
The lossless detection method of this check vacuum heat-insulating plate Gas leak position of the present invention, according to soaking into principle, can detect the particular location of film gas leakage, and operating process is simple, practical, can find the place of the trickle gas leakage in any place.

(2) side spray is soaked into liquid, makes to soak into liquid and is all covered in vacuum heat-insulating plate surrounding hot edge seal inside;
(3) vacuum heat-insulating plate after spraying is placed on to cool place, ventilation natural air drying 24 hours;
(4) above-mentioned vacuum heat-insulating plate encapsulating film is cut off, observed the position that core becomes color;
(5) according to soaking into immersion stain judgement Gas leak position: be immersed on inner glass cotton core material, wearing and tearing or crackle appear in the film that is judged as relevant position, cause gas leakage.
Method of the present invention, is characterized in that the liquid color of soaking in described step (1) is red.
Above are only single embodiment of the present invention, but design concept of the present invention is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should belong to the behavior of invading the scope of protection of the invention.In every case be the content that does not depart from technical solution of the present invention, any type of simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
