With the improvement of modern home decoration level, people prefer to choose aluminum alloy insulating glass windows when selecting doors and windows. While enjoying quiet and comfortable, many people find that the insulating glass of doors and windows is fogged. What's going on? In fact, this fogging phenomenon is caused by the unqualified manufacturing process of insulating glass for aluminum alloy doors and windows. To understand the causes and solutions, we must first understand the manufacturing process of insulating glass.

中空玻璃的基本制作工艺由玻璃的清洗、灌分子筛、丁基密封胶的涂敷、合片、涂第二道密封胶等环节组成。每一环节都与材料的选择及操作人员的熟练程度和加工质量有关。

The basic manufacturing process of insulating glass consists of glass cleaning, filling molecular sieve, coating butyl sealant, laminating, coating the second sealant and so on. Each link is related to the selection of materials, the proficiency of operators and processing quality.

下面小编大家详细介绍中空玻璃制作工艺流程：

The following editor will introduce the manufacturing process of insulating glass in detail:

一、玻璃清洗清洗玻璃是中空玻璃生产的一个环节，也是保证中空玻璃密封的更重要的环节之一。如果玻璃上的油滞和汗水不能彻底清洗掉，则密封胶对玻璃的粘合力就会大大削弱，从而降低中空玻璃的密封效果。

1、 Glass cleaning is not only a link in the production of insulating glass, but also one of the most important links to ensure the sealing of insulating glass. If the oil stagnation and sweat on the glass cannot be completely cleaned, the adhesion of the sealant to the glass will be greatly weakened, thus reducing the sealing effect of the insulating glass.

二、干燥剂的选择

2、 Selection of desiccant

放干燥剂目的是保持中空玻璃有合格的初始露点，因此，合格的干燥剂是必须同时满足干燥剂所应具有的三个功能。如果干燥剂吸附能力差，不能有用的吸附通过扩散进入空气层的水分，就会导致水分在空气层中聚集，水分压力提高，中空玻璃的露点上升，那么出现雾化的可能性极大。

The purpose of putting desiccant is to keep insulating glass with qualified initial dew point. Therefore, qualified desiccant must meet the three functions of desiccant at the same time. If the desiccant has poor adsorption capacity and can not effectively absorb the water diffused into the air layer, it will lead to the accumulation of water in the air layer, the increase of water pressure and the rise of dew point of insulating glass, then there is a great possibility of atomization.

另外选择干燥剂时必须综合考虑它们各自的性质，干燥剂的选择与所选用的中空玻璃胶类型有直接关系，必须结合起来考虑。

In addition, their respective properties must be comprehensively considered when selecting desiccant. The selection of desiccant is directly related to the type of insulating glass adhesive selected, which must be considered together.

三、双层中空玻璃的涂敷-合片-涂胶合片是制作双层中空玻璃的中间一环，合片前丁基胶的涂敷，决定着中空玻璃的综合质量。因此，制作时应严格控制生产工艺，杜绝漏涂、断胶现象和对封口的疏忽，决不允许存在漏气的隐患，把好密封的一关。合片后涂二道密封胶时，按生产厂家规定进行合理的配比，使两组份混合充分，涂胶准确，避免欠胶和多胶现象，圆满完成双层中空玻璃制作的一道工序。

3、 Coating lamination gluing lamination of double-layer insulating glass is the middle ring of making double-layer insulating glass. The coating of butyl glue before lamination determines the comprehensive quality of insulating glass. Therefore, the production process shall be strictly controlled during production, and the phenomenon of missing coating, glue breaking and negligence of sealing shall be eliminated. The hidden danger of air leakage shall not exist, and the sealing shall be well controlled. When applying two layers of sealant after lamination, carry out reasonable proportion according to the regulations of the manufacturer, so as to fully mix the two components, accurately apply glue, avoid insufficient glue and multi glue, and successfully complete a process of making double-layer insulating glass.
