How to identify the quality of insulating glass is good or bad? |
In recent years, the hollow glass industry rapid development, but due to lack of domestic basic theory of the insulating glass, plus some material supplier for the interest to exaggerate the publicity, so that the actual service life of the insulating glass to simply reach the time limit has expired. Not only to meet the energy efficiency, but a lot of social costs. The article describes several simple methods to identify the pros and cons of the insulating glass.
Extracted from the finished product of an insulating glass, and found to have any of the following phenomena, consumers can determine their substandard products, and request a return.
With a knife, two sealing cut a cross section, if the cross section is a lot of small pores (small cell), indicating that the two possibilities, one is hand-gluing will be wrapped into the air bubbles; Another possibility is that The low level of technology to produce the two sealants, use of machinery, plastic will also appear stomata, as long as the cross-section pores of its life is certainly very short.
Insulating glass connect the corners with a knife cut open the corner to see connections did not use butyl rubber wrapped. Actual theory suggests that Sealed insulating glass connection angle way to do dual channel, permeable paths in the four corners, the flooding was 70% edge permeable rate of only 30%. Maximize the use of consecutive bends an aluminum or butyl rubber 4 connection angle effectively wrapped, can greatly extend the life of insulating glass, butyl rubber on the four corners wrapped, double sealed The practical significance is not large.
Two seals and glass bonding the two sections with a knife, cut open a few centimeters, and then hand the sealant out of torn. Tear after the glass surface is smooth, no residual glue, sealant and the glass surface without adhesion, the sealing effect can be imagined.
(4) supplement. Examine whether using standard molecular sieve, butyl rubber is continuous (no break), if not the polysulfide rubber, the other two sealants done miscibility experiments (must be done miscibility experiment, otherwise it may be no end of trouble). Sealing window frames than the standard strip seal, but with ordinary silicone rubber seal, to the use of silicone rubber and hollow glass edge sealant compatibility experiments, or may also be no end of trouble (some doors and windows buy inferior oil-filled silicone rubber seal on the window frame, over time, the mineral oil to migrate out to erode the entire insulating glass sealing system such consequences will take some time to show it, so be sure to advance prevention). |
