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藝由玻璃的清洗、灌分子篩、丁基密封膠的涂敷、合片、涂第二道密封膠等環(huán)節(jié)組成。每一環(huán)節(jié)都與材料的選擇及操作人員的熟練程度和加工質(zhì)量有關(guān)。

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.

下面小編大家詳細(xì)介紹中空玻璃制作工藝流程：

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產(chǎn)的一個(gè)環(huán)節(jié)，也是保證中空玻璃密封的更重要的環(huán)節(jié)之一。如果玻璃上的油滯和汗水不能徹底清洗掉，則密封膠對(duì)玻璃的粘合力就會(huì)大大削弱，從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、干燥劑的選擇

2、 Selection of desiccant

放干燥劑目的是保持中空玻璃有合格的初始露點(diǎn)，因此，合格的干燥劑是必須同時(shí)滿足干燥劑所應(yīng)具有的三個(gè)功能。如果干燥劑吸附能力差，不能有用的吸附通過擴(kuò)散進(jìn)入空氣層的水分，就會(huì)導(dǎo)致水分在空氣層中聚集，水分壓力提高，中空玻璃的露點(diǎn)上升，那么出現(xiàn)霧化的可能性極大。

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.

另外選擇干燥劑時(shí)必須綜合考慮它們各自的性質(zhì)，干燥劑的選擇與所選用的中空玻璃膠類型有直接關(guān)系，必須結(jié)合起來考慮。

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、雙層中空玻璃的涂敷-合片-涂膠合片是制作雙層中空玻璃的中間一環(huán)，合片前丁基膠的涂敷，決定著中空玻璃的綜合質(zhì)量。因此，制作時(shí)應(yīng)嚴(yán)格控制生產(chǎn)工藝，杜絕漏涂、斷膠現(xiàn)象和對(duì)封口的疏忽，決不允許存在漏氣的隱患，把好密封的一關(guān)。合片后涂二道密封膠時(shí)，按生產(chǎn)廠家規(guī)定進(jìn)行合理的配比，使兩組份混合充分，涂膠準(zhǔn)確，避免欠膠和多膠現(xiàn)象，圓滿完成雙層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.
