在中空玻璃的生產中，雙道密封中空玻璃生產可靠性高而廣泛使用。雙組份中空玻璃膠的涂布有2種方式機器涂布跟手工涂布。目前采用手工涂布的中空玻璃生產因成本低投資少被大多生產廠家采用。
In the production of insulating glass, double sealed insulating glass is widely used because of its high reliability. Two component insulating glass adhesive coating has two ways: machine coating and manual coating. At present, the production of insulating glass by hand coating is adopted by most manufacturers because of its low cost and low investment.
但手工刮膠中空玻璃存在以下無法避免的3個缺 陷
However, there are three unavoidable defects in manual scraping insulating glass
一、配比不一致
1、 The ratio is inconsistent
二、調配不均勻
2、 Uneven deployment
三、無法使膠在混合后立即涂在中空玻璃上，讓其在玻璃上完成開始硫化至完全硫化這一過程
3、 It is impossible to apply the rubber on the insulating glass immediately after mixing, so that it can complete the process from vulcanization to complete vulcanization on the glass

雙組份打膠機的出現滿足了上述手工刮膠時無法避免的三個缺 陷。同時經打膠機高壓涂至玻璃邊緣上的膠結構密實，而同樣的膠手工混合后涂至玻璃上就松軟有氣泡。就像水泥混凝土經震動震實的結構性強，而未經震實的混凝土就算加大水泥的配合量也無法達到所需強度。所以高標準的中空玻璃如幕墻中空都要求一定采用機涂的方式生產。
The appearance of the two-component gluing machine first meets the three unavoidable defects in manual scraping. At the same time, the structure of the glue applied to the edge of the glass under high pressure by the beater is dense, while the same glue is soft and has bubbles when applied to the glass after manual mixing. Just like the structural strength of cement concrete after vibration compaction, the concrete without vibration compaction can not reach the required strength even if the cement mix is increased. Therefore, high standard insulating glass, such as curtain wall, must be produced by machine coating.
目前，世界上雙組份打膠機的使用建議采用配套的雙組份機涂膠，而機涂膠實際上就是經過充分研磨過濾的手涂膠，這種膠流動性好細膩無雜質，可這種膠對膠本身的密封性能關系不大，僅僅是為了配合機器的可操作性能，就是這樣經過精細物理加工的膠。
At present, the world's use of two-component gluing machine must adopt the matching two-component gluing machine, and the machine gluing is actually hand gluing after full grinding and filtration. This kind of glue has good fluidity, fine and no impurities, but this kind of glue has little to do with the sealing performance of the glue itself, just to match the operability of the machine, which is the glue after fine physical processing.
在使用時堵塞機器也是常有的事如果用普通手工刮膠放在機器里施工作業不出10分鐘機器就無法工作了。
It is also common to block the machine when it is in use. If ordinary manual scraping glue is put in the machine for construction, the machine will not work within 10 minutes.
