影響中空玻璃設備質量的因素主要有原材料的選用和生產制造工藝。其中原材料的質量將直接影響中空玻璃的質量和使用壽命。目前國內中空玻璃主要有三種：槽鋁式單道密封、槽鋁式雙道密封、復合密封膠條式中空玻璃。槽鋁式單道密封因其密封性差，易進潮氣，導致玻璃結露、結霜，使用壽命短，已逐漸被淘汰。
The main factors affecting the quality of insulating glass equipment are the selection of raw materials and manufacturing technology. The quality of raw materials will directly affect the quality and service life of insulating glass. At present, there are three kinds of insulating glass in China: grooved aluminum single channel seal, grooved aluminum double channel seal and composite sealant strip insulating glass. Trough aluminum single pass seal has been gradually eliminated because of its poor sealing performance and easy moisture entry, resulting in glass condensation and frosting and short service life.
在玻璃材料給定后，比如普通平板玻璃或鋼化玻璃，那么根據玻璃強度設計理論，玻璃原片的斷裂強度就確定下來了。由于中空玻璃機器生產的玻璃是由兩片（或兩片以上）玻璃構成，周邊密封形成一個密封的空氣層，中空玻璃在一面玻璃受到載荷作用時，受力面玻璃變形壓縮中空層氣體，氣體壓強加大，將部分載荷傳送給另一面玻璃，因此在氣體密封狀態下，中空玻璃是兩片玻璃共同承擔載荷，兩片玻璃同時變形。中空玻璃是兩層或多層平板玻璃由灌注了干燥劑的鋁框用丁基波和聚硫膠粘結而成。

After the glass material is given, such as ordinary flat glass or tempered glass, the breaking strength of the original glass sheet is determined according to the glass strength design theory. The glass produced by the insulating glass machine is composed of two (or more) pieces of glass, and the surrounding seal forms a sealed air layer. When one side of the insulating glass is loaded, the glass on the stress surface deforms and compresses the gas in the insulating layer, the gas pressure increases, and part of the load is transmitted to the other side of the glass. Therefore, in the gas sealed state, Insulating glass is that two pieces of glass bear the load together, and the two pieces of glass deform at the same time. Insulating glass is two or more layers of flat glass, which is made of aluminum frame filled with desiccant and bonded with butyl wave and polysulfide glue.

制造中空玻璃設備的原片玻璃可以是無色浮法玻璃、鍍膜玻璃、鋼化玻璃、夾層玻璃等。應避免使用普通平板玻璃，普通平板玻璃的透明度及強度均達不到要求。上述玻璃原片必 須符合相應標準要求，經檢驗合格后才能使用。
The original glass for manufacturing insulating glass equipment can be colorless float glass, coated glass, tempered glass, laminated glass, etc. The use of ordinary flat glass shall be avoided. The transparency and strength of ordinary flat glass cannot meet the requirements. The original glass sheet must meet the requirements of corresponding standards and can be used only after passing the inspection.
不同廠家不同批次的玻璃在切割前應首先檢查有無色差，將色差較大的玻璃分別用于不同的工程或不同的建筑立面中。玻璃切割尺寸應按圖紙要求嚴格執行，同時操作人員應注意玻璃表面，不得有劃傷、氣泡等明顯缺陷。
Before cutting different batches of glass from different manufacturers, first check whether there is color difference, and use the glass with large color difference in different projects or different building facades. The glass cutting size shall be strictly implemented according to the requirements of the drawing. At the same time, the operator shall pay attention to the glass surface without obvious defects such as scratches and bubbles.
鋁條、插角的選用：鋁條的厚度應在0.30mm～0.35mm之間，厚度應均勻一致，透氣孔分布均勻。鋁條須經陽極氧化處理或去污處理，一定要選用質量好、檔次高的產品，提高鋁條利用率。插角尺寸要選好，表面要擦干凈。
Selection of aluminum strip and insertion angle: the thickness of aluminum strip shall be between 0.30mm and 0.35mm, the thickness shall be uniform, and the vent holes shall be evenly distributed. Aluminum strips must be anodized or decontaminated. Products with good quality and high grade must be selected to improve the utilization rate of aluminum strips. The size of the insertion angle shall be selected and the surface shall be cleaned.
