The sealing of insulating glass mainly uses sealant, which plays a sealing role of insulating glass. The sealing of insulating glass, in addition to UV radiation testing whether the insulating glass sealant contains organic volatile substances that affect vision, the other four indicators "sealing performance, initial dew point, high temperature and humidity, and climate cycle" are all used to test the sealing performance of insulating glass in various environments.

可能很多人会疑问，中空玻璃自动打胶机的打胶环节和中空玻璃有什么关系。接下来，我们就给大家一起来说一下中空玻璃自动打胶机的打胶环节和中空玻璃的关系。

Many people may question the relationship between the gluing process of the automatic gluing machine for insulated glass and insulated glass. Next, let's talk about the gluing process of the automatic gluing machine for insulated glass and its relationship with insulated glass.

槽铝式双道密封中空玻璃第一道密封用丁基胶，具有极低的水蒸气透过率；第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。当中空玻璃第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。

The first sealing layer of the aluminum groove double sealed hollow glass is made of butyl rubber, which has an extremely low water vapor transmission rate; The second layer of sealant mainly includes polysulfide adhesive and silicone adhesive. The interval aluminum frame should adopt a continuous long pipe bending angle type, and the joints should be sealed with butyl adhesive; If the spacing aluminum frame adopts a four corner plug-in type, each joint should also be sealed with butyl rubber, and the hollow glass made from this has a shorter service life than the former. When the second layer of sealant for insulating glass uses silicone adhesive, insulating glass with four corner plug-in spacing aluminum frames 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极低，但结构性差的聚异丁烯胶作为中空玻璃的第一道密封胶，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。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。

Single sealed insulating glass is difficult to meet the sealing performance of insulating glass. To compensate for the insufficient sealing performance of these adhesives, polyisobutylene adhesive with extremely low water vapor permeability but poor structure is usually used as the first sealant of insulating glass to prevent moisture from penetrating into the insulating glass. This is the traditional production process of double sealed insulating glass, which is familiar to everyone. Due to the performance defects of the two types of sealants used in double sealed insulating glass, only a combination of the two (i.e. double sealed) can meet the sealing and structural indicators of insulating glass. There are now some new types of hollow glass sealants: structural hot melt butyl sealants.

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第一道密封。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。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。

The insulated glass gluing machine is mainly used for the gluing process of insulated glass, which is commonly referred to as the sealing process. The insulating glass gluing machine is mainly designed for the first sealing of insulating glass. After using specialized equipment to heat and melt the hot melt butyl adhesive, apply the butyl adhesive to the coating area of the hollow glass using a hollow glass gluing machine. The gluing speed needs to be controlled well, because butyl rubber cools down and forms shape in a few minutes, and the gluing speed should not be too fast or too slow. If the glue is applied too quickly, it is easy to cause insufficient filling, which will affect the sealing of the hollow glass in the future. The problem of affecting the efficiency of the hollow glass gluing machine when it is too slow.
