1.玻璃清洗
1. Glass cleaning
清洗玻璃是中空玻璃生產的一個環節，也是保證中空玻璃密封性的非常重要的環節之一。如果玻璃上的油漬和汗水不能完全清洗掉，密封膠對玻璃的粘合力就會大大削弱，從而降低中空玻璃的密封效果。現在的生產中，很多廠家特別是小廠家，往往對清洗玻璃的重視程度不夠，造成大量不合格產品流入市場
Cleaning glass is not only a link in the production of insulating glass, but also one of the very important links to ensure the sealing of insulating glass. If the oil stains 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. In the current production, many manufacturers, especially small manufacturers, often do not pay enough attention to cleaning glass, resulting in a large number of unqualified products flowing into the market
2.干燥劑選擇
2. Desiccant selection
選擇干燥劑時一定要綜合考慮干燥劑的性質。干燥劑的選擇與所選用的中空玻璃膠的類型有直接關系，一定要結合起來考慮。中空玻璃的邊緣密封失敗，意味著門窗失去應有的功能，不但門窗的節能性能達不到要求，而且消費者不能透過結霧的空氣層看清外面，影響中空玻璃的透明度，并降低隔熱效果。長時間的結霧會使玻璃的內表面發生霉變或積堿，產生白斑，嚴重影響中空玻璃的外觀質量。由此可見，選擇高質量的中空玻璃密封膠是防止中空玻璃結霧的關鍵選用的中空玻璃密封膠應符合國家或行業標準要求，并且雙層中空玻璃的一道和二道密封膠應相適合，不能互溶或有反應，否則有可能導致玻璃表面污染，甚至老化。
When choosing desiccant, we must comprehensively consider the properties of desiccant. The choice of desiccant is directly related to the type of insulating glass adhesive selected, which must be considered together. The failure of edge sealing of insulating glass means that the doors and windows lose their due functions. Not only the energy-saving performance of doors and windows can not meet the requirements, but also consumers can not see the outside through the fogged air layer, which affects the transparency of insulating glass and reduces the heat insulation effect. Fogging for a long time will cause mildew or alkali accumulation on the inner surface of the glass, resulting in white spots, which will seriously affect the appearance quality of the insulating glass. It can be seen that the selection of high-quality insulating glass sealant is the key to prevent the fogging of insulating glass. The selected insulating glass sealant should meet the requirements of national or industrial standards, and the first and second sealants of double-layer insulating glass should be suitable, which can not dissolve or react with each other. Otherwise, the glass surface may be polluted or even aged.

3.雙層中空玻璃涂敷
3. Double insulating glass coating
合片是制作雙層中空玻璃的中間一環。合片前丁基膠的涂敷，決定著中空玻璃的綜合質量。如果兩道密封膠之間存在縫隙，會引起漏氣。同時應注意涂抹過薄的二道密封膠。在安裝使用一段時間后，受環境溫度變化、日曬及風壓的作用，密封膠會形成裂紋，即使是非常小的裂紋，水汽就有可能慢慢地進入膠層內，形成結霧，使密封膠喪失密封作用。
Lamination is the middle ring of making double-layer insulating glass. The coating of butyl adhesive before lamination determines the comprehensive quality of insulating glass. If there is a gap between the two layers of sealant, it will cause air leakage. At the same time, pay attention to applying too thin two layers of sealant. After installation and use for a period of time, the sealant will form cracks due to the changes of ambient temperature, sunlight and wind pressure. Even if it is a very small crack, the water vapor may slowly enter the adhesive layer and form fog, so that the sealant will lose its sealing effect.
除了一些正規中空玻璃廠因產品質量問題而出現結霧現象外，一些消費者片面追求低價產品，也使得一些不法商販有*可乘，他們采用雙面膠將兩片玻璃直接粘連起來，再涂上普通的玻璃膠，冒充中空玻璃，此種玻璃不但沒有隔音隔熱作用，遇上潮濕天氣就會產生結霧現象。一旦出現中空玻璃結霧現象，基本無法維修，只能更換。
In addition to the fogging phenomenon of some regular insulating glass factories due to product quality problems, some consumers unilaterally pursue low-cost products, which also makes some illegal vendors have * to take advantage of. They use double-sided adhesive tape to directly bond the two pieces of glass, and then apply ordinary glass adhesive to fill the insulating glass. This kind of glass not only has no sound insulation and heat insulation effect, but also fogging will occur in wet weather. In case of fogging of insulating glass, it is basically impossible to repair and can only be replaced.
