中空玻璃的密封主要采用密封膠，起到中空玻璃的密封作用。中空玻璃的密封，除紫外線照射是測(cè)試中空玻璃密封膠是否含有影響視線的有 機(jī)揮發(fā)物外，另外四項(xiàng)指標(biāo)“密封性能、高溫高濕、氣候循環(huán)”，都是檢測(cè)中空玻璃在各種環(huán)境下的密封性能的。中空玻璃的密封主要采用密封膠，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.
槽鋁式雙道密封中空玻璃一道密封用丁基膠，具有低的水蒸氣透過(guò)率；二道密封膠主要有聚硫膠和硅酮膠。間隔鋁框宜采用連續(xù)長(zhǎng)管彎角式，接頭處應(yīng)用丁基膠做密封處理；間隔鋁框如采用四角插接式，其各個(gè)接頭處亦應(yīng)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(dāng)中空玻璃二道密封膠采用硅酮膠時(shí)，不應(yīng)采用四角插接式間隔鋁框的中空玻璃。
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.
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(bǔ)這些膠的密封性能的不足，通常采用水汽透過(guò)率低，但結(jié)構(gòu)性差的聚異丁 烯膠作為中空玻璃的一道密封膠，以阻止潮氣向中空玻璃內(nèi)滲 透，這就是傳統(tǒng)的大家熟悉的雙道密封中空玻璃的生產(chǎn)工藝。
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(jié)合的方式（即雙道密封式）才能滿足中空玻璃的密封性和結(jié)構(gòu)性指標(biāo)?，F(xiàn)在有一些新型中空玻璃密封膠：結(jié)構(gòu)型熱熔丁基密封膠。
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.
中空玻璃打膠機(jī)主要用于中空玻璃的打膠環(huán)節(jié)，也就是我們平時(shí)所說(shuō)的密封環(huán)節(jié)。中空玻璃打膠機(jī)主要針對(duì)中空玻璃的一道密封。使用專用設(shè)備將熱熔丁基膠加熱熔化后，用中空玻璃打膠機(jī)將丁基膠涂至中空玻璃的涂膠部位。
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.
這個(gè)打膠速度要掌握好，因?yàn)槎』z幾分鐘就冷 卻定型，打膠速度不宜過(guò)快過(guò)慢。過(guò)快的情況下很容易導(dǎo)致打膠不飽滿，日后影響中空玻璃的密封問(wèn)題。過(guò)慢的情況下影響中空玻璃打膠機(jī)的工作效率問(wèn)題。
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.
