1, rotation speed: in a centrifuge tube expansion process, the rotational speed and diameter determined centrifugal force. When the diameter is constant, the higher the speed, the greater the centrifugal force. Under centrifugal force, the larger the 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.

principle

The purpose is to eliminate permanent stress and structural imbalance in glass products. Glass is a poor heat conductor. After the product is formed, a temperature difference occurs between the surface layer and the inner layer during the cooling process. When the surface layer is solidified and the inner layer is viscous, the temperature difference exists but the stress relaxation does not exist. This temperature difference is when the surface layer is cooled to room temperature. , the inner layer continues to cool down and shrink, and is hindered by the surface layer to generate tensile stress, and at the same time, the surface layer generates compressive stress, which exists permanently
