中空玻璃的密封主要采用密封胶，起到中空玻璃的密封作用。中空玻璃的密封，除紫外线照射是测试中空玻璃密封胶是否含有影响视线的有 机挥发物外，另外四项指标“密封性能、高温高湿、气候循环”，都是检测中空玻璃在各种环境下的密封性能的。中空玻璃的密封主要采用密封胶，起到中空玻璃的密封作用。
The sealing of insulating glass mainly uses sealant, which plays the sealing role of insulating glass. The sealing of insulating glass, in addition to ultraviolet radiation is to test whether the insulating glass sealant contains organic volatiles that affect the line of sight, the other four indicators "sealing performance, high temperature and high humidity, climate cycle" are used to test the sealing performance of insulating glass in various environments. The sealing of insulating glass mainly uses sealant, which plays the sealing role of insulating glass.
槽铝式双道密封中空玻璃一道密封用丁基胶，具有低的水蒸气透过率；二道密封胶主要有聚硫胶和硅酮胶。间隔铝框宜采用连续长管弯角式，接头处应用丁基胶做密封处理；间隔铝框如采用四角插接式，其各个接头处亦应用丁基胶做密封处理，以此做成的中空玻璃，使用寿命不如前者。当中空玻璃二道密封胶采用硅酮胶时，不应采用四角插接式间隔铝框的中空玻璃。
Aluminum double channel sealing insulating glass with butyl rubber for one channel sealing has low water vapor permeability; The second sealant mainly includes polysulfide sealant and silicone sealant. The aluminum frame should be of continuous long pipe bending type, and the joints should be sealed with butyl rubber; If the aluminum frame is of four corner plug-in type, the joints are sealed with butyl rubber. The service life of the insulating glass made of this type is not as long as that of the former. When silicone sealant is used for secondary sealant of insulating glass, insulating glass with four corner plug-in aluminum frame should not be used.
单道密封中空玻璃是难以满足中空玻璃的密封性能的。为弥补这些胶的密封性能的不足，通常采用水汽透过率低，但结构性差的聚异丁 烯胶作为中空玻璃的一道密封胶，以阻止潮气向中空玻璃内渗 透，这就是传统的大家熟悉的双道密封中空玻璃的生产工艺。
It is difficult to meet the sealing performance of insulating glass with single seal. In order to make up for the lack of sealing performance of these adhesives, polyisobutylene adhesive with low water vapor permeability but poor structure is usually used as a sealant of insulating glass to prevent moisture from penetrating into the insulating glass. This is the traditional production process of double sealing insulating glass.
由于双道密封中空玻璃所采用的二种密封胶各自性能上的缺 陷，只能采用两者结合的方式（即双道密封式）才能满足中空玻璃的密封性和结构性指标。现在有一些新型中空玻璃密封胶：结构型热熔丁基密封胶。
Due to the defects of the two kinds of sealants used in the double sealing insulating glass, the sealing and structural indexes of the insulating glass can only be met by the combination of the two kinds of sealants. Now there are some new insulating glass sealant: structural hot melt butyl sealant.
中空玻璃打胶机主要用于中空玻璃的打胶环节，也就是我们平时所说的密封环节。中空玻璃打胶机主要针对中空玻璃的一道密封。使用专用设备将热熔丁基胶加热熔化后，用中空玻璃打胶机将丁基胶涂至中空玻璃的涂胶部位。
The insulating glass gluing machine is mainly used for the gluing link of insulating glass, which is what we usually call the sealing link. Insulating glass gluing machine is mainly used to seal insulating glass. Use special equipment to heat and melt the hot-melt butyl rubber, and then use insulating glass beater to apply butyl rubber to the gluing part of insulating glass.
这个打胶速度要掌握好，因为丁基胶几分钟就冷 却定型，打胶速度不宜过快过慢。过快的情况下很容易导致打胶不饱满，日后影响中空玻璃的密封问题。过慢的情况下影响中空玻璃打胶机的工作效率问题。
This tapping speed should be controlled well, because butyl rubber will cool and set in a few minutes, and the tapping speed should not be too fast or too slow. If it is too fast, it is easy to lead to insufficient gluing, which will affect the sealing of insulating glass in the future. Too slow affects the efficiency of the insulating glass glue machine.
