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.

可能很多人會疑問，中空玻璃自動打膠機的打膠環節和中空玻璃有什么關系。接下來，我們就給大家一起來說一下中空玻璃自動打膠機的打膠環節和中空玻璃的關系。

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.

槽鋁式雙道密封中空玻璃第一道密封用丁基膠，具有極低的水蒸氣透過率；第二道密封膠主要有聚硫膠和硅酮膠。 間隔鋁框宜采用連續長管彎角式，接頭處應用丁基膠做密封處理；間隔鋁框如采用四角插接式，其各個接頭處亦應用丁基膠做密封處理，以此做成的中空玻璃，使用壽命不如前者。當中空玻璃第二道密封膠采用硅酮膠時，不應采用四角插接式間隔鋁框的中空玻璃。

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.

單道密封中空玻璃是難以滿足中空玻璃的密封性能的。為彌補這些膠的密封性能的不足，通常采用水汽透過率極低，但結構性差的聚異丁烯膠作為中空玻璃的第一道密封膠，以阻止潮氣向中空玻璃內滲透，這就是傳統的大家熟悉的雙道密封中空玻璃的生產工藝。由于雙道密封中空玻璃所采用的二種密封膠各自性能上的缺陷，只能采用兩者結合的方式（即雙道密封式）才能滿足中空玻璃的密封性和結構性指標。現在有一些新型中空玻璃密封膠：結構型熱熔丁基密封膠。

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.

中空玻璃打膠機主要用于中空玻璃的打膠環節，也就是我們平時所說的密封環節。中空玻璃打膠機主要針對中空玻璃的第一道密封。使用專用設備將熱熔丁基膠加熱熔化后，用中空玻璃打膠機將丁基膠涂至中空玻璃的涂膠部位。這個打膠速度要掌握好，因為丁基膠幾分鐘就冷卻定型，打膠速度不宜過快過慢。過快的情況下很容易導致打膠不飽滿，日后影響中空玻璃的密封問題。過慢的情況下影響中空玻璃打膠機的工作效率問題。

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.
