在中空玻璃的生产中，双道密封中空玻璃生产可靠性高而广泛使用。双组份中空玻璃胶的涂布有2种方式机器涂布跟手工涂布。目前采用手工涂布的中空玻璃生产因成本低投资少被大多生产厂家采用。
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.
但手工刮胶中空玻璃存在以下无法避免的3个缺 陷
However, there are three unavoidable defects in manual scraping insulating glass
一、配比不一致
1、 The ratio is inconsistent
二、调配不均匀
2、 Uneven deployment
三、无法使胶在混合后立即涂在中空玻璃上，让其在玻璃上完成开始硫化至完全硫化这一过程
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

双组份打胶机的出现满足了上述手工刮胶时无法避免的三个缺 陷。同时经打胶机高压涂至玻璃边缘上的胶结构密实，而同样的胶手工混合后涂至玻璃上就松软有气泡。就像水泥混凝土经震动震实的结构性强，而未经震实的混凝土就算加大水泥的配合量也无法达到所需强度。所以高标准的中空玻璃如幕墙中空都要求一定采用机涂的方式生产。
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，世界上双组份打胶机的使用必须采用配套的双组份机涂胶，而机涂胶实际上就是经过充分研磨过滤的手涂胶，这种胶流动性好细腻无杂质，可这种胶对胶本身的密封性能关系不大，仅仅是为了配合机器的可操作性能，就是这样经过精细物理加工的胶。
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.
在使用时堵塞机器也是常有的事如果用普通手工刮胶放在机器里施工作业不出10分钟机器就无法工作了。
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.
