Chemical Resistance Long 13mm Glass Tubing High Strength

Chemical Resistance Neutral Glass Tube Good Electrical Performance

High mechanical strength. The relative molecular weight of plexiglass is about 2 million. It is a long-chain polymer compound, and the chains that form the molecules are very soft. Therefore, the strength of plexiglass is relatively high, and its tensile and impact resistance are 7～higher than ordinary glass. 18 times. There is a kind of plexiglass that has been heated and stretched, in which the molecular chains are arranged in a very orderly manner, which significantly improves the toughness of the material. Use nails to penetrate this plexiglass, even if the nail penetrates, there will be no cracks on the plexiglass. This kind of plexiglass will not break into pieces after being penetrated by a bullet. Therefore, the stretched plexiglass can be used as bulletproof glass, and also used as a cockpit cover on military aircraft.

1, rotation speed: in a centrifuge tube expansion process, the rotational speed and diameter determined centrifugal force. When the pipe diameter is constant, the higher the speed, the greater the centrifugal force. Under the action of centrifugal force, the larger the pipe diameter, the slower the speed. Thus, during the pipe expansion rate should be used as the basis to the diameter of the glass tube
2, the wall thickness is determined, and the corresponding temperature. Heating and softening the pressure in the pipe expansion process, the control diameter sizing device mainly depends on a set of synchronous rotation of the glass tube, it requires a wider range of speeds.
