Pipe, cannot produce rectangular glass tube;Blowing is mainly used for spherical class, the production of circular glass bulb, and part company also attempts progress side
The blowing of shape glass bulb, but the glass of this special shape of blowing method square shaped has certain limitation, production, glass by hand
It is difficult to meet the size requirement of electric-vacuum glass in terms of shell evenness of wall thickness, consistency.Therefore both methods is true in electricity at present
There is biggish limitation in empty glass production, limit the production of rectangular glass bulb substantially.Although part research unit and enterprise
Also the method that gradually development uses glass blower realizes the molding making of some special shapes such as square, hexagon glass bulb, but
The deficiencies of to be that this technique equally controls by hand, there are consistency bad, production efficiency is low, energy consumption is high, significantly limits
The requirement of mass production.Glass bulb is as the important composition component in photomultiplier tube, machining accuracy, consistency, shape etc.
Various aspects quality all directly affects the final performance index of photomultiplier tube, therefore the limitation that electric-vacuum glass routinely produces
Restrict the development and production of photomultiplier tube to a certain extent.The effective glass tube of photomultiplier transit requires ratio for size and material
It is higher, also cause current buying approach limited, basic limitation adopts enterprise in a small amount of manufacturer based on German Xiao Te
Purchase increased costs, procurement cycle are elongated.
