Acidic Oxide Medical Neutral Glass Tube Thermal Shock Resistance 1-20ml

Thermal Shock Resistance Neutral Glass Tube

High mechanical strength. PMMA relative molecular weight of about 200 million. It is a long chain polymer compound, the molecular chains form a very soft. Therefore, the strength of plexiglass is relatively high, and its tensile and impact resistance are 7 to 7 times higher than that of ordinary glass. 18 times. There is a heated stretching plexiglass, very orderly arranged molecular chain, significantly increase the toughness of the material. Use a nail to pierce this piece of plexiglass. Even if the nail is pierced, the plexiglass will not crack. This breakdown of the PMMA is not broken bullet. Thus, bullet-proof glass can be used as organic glass after stretching, it may also be used in military aircraft cockpit cover.

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.
