1 slot aluminum double-sealed insulating glass primary seal with butyl rubber, has a very low water vapor transmission rate; secondary sealants are mainly polysulfide and silicone rubber. Polysulfide rubber water vapor transmission rate of less than silicone rubber, UV resistance but not as good as silicone rubber, it applies to window or curtain wall (aluminum frame due to shade, avoid direct sunlight); silicone gel is applicable to hidden frame glass curtain wall, its UV resistance and strength are higher than polysulfide rubber. When the construction of insulating glass with high decorative requirements of insulating glass, the choice of white or transparent silicone rubber. Wooden windows are hanged as a secondary sealing silicone rubber, because of its resistance to poor wood preservative products, sealants damaged due to migration. Although the basic theory of hollow glass Jinan domestic system is not perfect, but in recent years the rapid development of the domestic lowe insulating glass and insulating glass, various types of insulating glass production equipment widely used in the production practice, while in the past 20 years of hollow Glass has accumulated a lot of history of the development of both positive and negative experiences of 595 hollow glass, now following quality control approach are summarized as follows: 1, good technology is to improve the quality of glass Jinan effective way to 612a6 hollow glass, hollow Jinan glass industry is concerned, constitute a better production process must have the following elements: first, the continuity of the production line, only with the production line in order to ensure the continuity of hollow glass products from raw glass to finished qualifying with acceptable quality consistency, and maximize production efficiency; and second, whether the first or the second seal sealed equipment to maximize the use of sealed plastic high degree of automation equipment, the only way to minimize the impact of human factors on the quality. lowe hollow glass, Yaohui trustworthy, hollow glass provided by Jinan Shandong Glass Co., Ltd. Yaohui. lowe hollow glass, Yaohui trustworthy, Shandong Jinan Yaohui hollow glass Glass Co., Ltd.
