Briefly said that the glass and metal sealing can be matched to the matching and non matching of the two major categories.
Matching sealing is the direct sealing of glass and metal, but it is necessary to select the glass and metal in the vicinity of the coefficient of expansion and shortening, so that the stress in the glass after sealing can be within the scope of the promise. In general, some metal is equipped with a special glass to seal, such as aluminum and aluminum group glass sealing, steel and Steel Group glass sealing, which is a method of glass and metal sealing.
Two, non matching sealing is the expansion coefficient of metal and glass or other two kinds of information to be sealed, and mutual sealing method. In case of direct sealing, the glass in the seal will have a greater risk of occurrence.
Glass sealing can also be classified according to the skills. Can be divided into the following:
1, flame seal 2, induction sealing 3, high frequency resistance welding sealing 4, dispersing pressure sealing 5, powder glass sealing, 6 glass sealing, 7 silver chloride sealing
Glass sealing of the third classification methods are in accordance with the metal parts of the shape of a few, can be divided into five categories:
1, bead seal 2, tubular sealing sealing disc 3, 4, 5, pinnate marginal sealing strip sealing
Glass sealing and finally a classification method:
1, direct sealing 2, direct sealing
The original glass sealing method can also be classified in other ways, these are the more common classification approach, if you want to learn more about the details of the glass seal, please call the Advisory
