防治中空玻璃起雾的四条措施!

发布时间:2019/04/29    发布人:

全自动封胶机厂家救国研究发现░,导致中空玻璃起雾的原因无非是:密封失效而漏气░,或密封完好但干燥剂不能完全吸收中空腔体内的水汽░,在室内外温差的作用下腔体内水汽凝结在玻璃表面发生结露现象。所谓结露就像我们平时吃的雪糕一样░,我们用纸巾把塑料包装表面上的水擦干后░,很快表面又有新的水滴产生░,这是因为空气中的水汽遇冷凝结在雪糕包装外表面(即温差作用)。
According to the national salvation study by the manufacturer of automatic sealant machine, the causes of fogging in hollow glass are as follows: the seal fails and leaks, or the seal is intact, but the desiccant can not absorb the water vapor in the hollow cavity completely, and the water vapor in the cavity condenses on the glass surface under the action of the temperature difference between indoor and outdoor. The so-called condensation is just like the ice-cream we usually eat. After we wipe the water on the plastic packaging surface with paper towels, new water droplets will appear on the surface soon. This is because the moisture in the air condenses on the outside surface of the ice-cream packaging (i.e. the effect of temperature difference).
所以░,只有做好了以下四点░,中空玻璃不充气也不会起雾(结露):
Therefore, only if the following four points are made, the hollow glass will not be inflated or foggy (condensation):
1.第一道密封胶即丁基胶(丁基胶带)一定要均匀连续░,压合后宽度3mm以上。这道密封胶就是连接在铝间隔条与玻璃之间░,之所以选择丁基胶(丁基胶带)░,是因为丁基胶有着其它胶无法比拟的抗水汽渗透率和抗透气性?梢运░,中空玻璃80%以上的抗水汽渗透任务都在这一道胶上░,如果密封不好░,中空玻璃漏气░,做再多其它的工作玻璃也会起雾。
1. The first sealant, butyl rubber (butyl rubber tape), must be uniform and continuous, with a width of more than 3 mm after pressing. This sealant is connected between aluminium spacer and glass. The reason why butyl rubber (butyl tape) is chosen is that butyl rubber has incomparable water vapor permeability and air permeability. It can be said that more than 80% of the anti-water vapor penetration tasks of hollow glass are on this glue. If the seal is not good, the hollow glass leaks, and do more work, the glass will fog.
2.第二道密封胶的选择?悸堑椒雷贤庀咭蛩░,现在门窗玻璃大部分采用AB双组份硅酮胶。硅酮胶虽然水汽密性较差░,但是能起到很好的辅助密封•●、粘结和保护作用。

2. Selection of the second sealant. Considering the anti-ultraviolet factors, most of the windows and doors now use AB two-component silicone gel. Although the water vapor tightness of silicone gel is poor, it can play a very good auxiliary sealing, bonding and protection role.
3.中空玻璃干燥剂3A分子筛也非常重要。3A分子筛的特性是只吸收水汽░,不吸收其它任何气体。只有足够的3A分子筛才会把中空玻璃中空腔内的水汽吸收░,保持了气体的干燥░,才不会产生起雾结露现象░,质量良好的中空玻璃即使在零下70度的环境下也不会有结露现象。
3. Hollow glass desiccant 3A molecular sieve is also very important. The characteristic of 3A zeolite is that it absorbs only water vapor and does not absorb any other gases. Only enough 3A molecular sieves can absorb the water vapor in the hollow glass cavity, keep the gas dry, and will not produce fogging condensation phenomenon. Even in the environment of 70 degrees below zero, the hollow glass with good quality will not have condensation phenomenon.
4.此外░,中空玻璃起不起雾还跟生产工艺有关。灌装好分子筛的铝间隔条░,不能放置过久才合片░,尤其在雨季或像广东春季的回潮天气░,更要注意控制合片时间。因为放置过久中空玻璃会吸收空气中的水份░,吸水饱和的分子筛会失去吸咐作用░,合片后因为不能吸收中空腔内的水份而产生起雾。另外░,分子筛的灌装多少也与起雾不起雾有着直接的关系。
4. In addition, it is also related to the production process that the hollow glass can not fog. Aluminum spacers for filling molecular sieves should not be placed too long before they are laminated, especially in rainy season or in spring tide weather like Guangdong Province. More attention should be paid to controlling the time of lamination. Because the hollow glass will absorb water in the air for too long, the molecular sieve with saturated water absorption will lose its adsorbing function, and fog will occur when the film is combined because it can not absorb water in the hollow cavity. In addition, the filling of molecular sieves has a direct relationship with fogging and non-fogging.
