British glass is a non-metallic tube. It is based on sodium oxide (Na2O), boron oxide (B2O3) and silicon dioxide (SiO2) glass. Its good performance has been recognized by the international community. Compared with ordinary glass, it has no toxic side effects. Mechanical properties, thermal stability, water, alkali, acid and other properties are greatly improved. It can be widely used in chemical, aerospace, defense, home, hospital, etc., with good promotional value and social benefits. This glass appeared in our country, is another new revolution in basic materials industry.

Quality assurance conditions include




◆ GMP production environment


◆ Online statistical control


◆ meet ISO size and appearance AQL level


◆ detecting camera parameters and critical size defects in appearance key 77


◆ Each product can be traced to the time of delivery (DD-MM-YY), shift, machine and operator.


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.




The purpose is to eliminate permanent stress and structural imbalance in glass products. Glass is a poor thermal conductor. After the product is formed, the surface layer and the inner layer will have a temperature difference 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 occurs when the surface layer is cooled to room temperature. , The inner layer continues to cool down and shrinks, which is hindered by the surface layer to produce tensile stress, and at the same time, the surface layer produces compressive stress, which is permanent. The size and distribution of the permanent stress caused by the thermal process in each part of the product will not be uniform, therefore, it will affect the strength of the glass product, and even break by itself due to stress concentration. Annealing can eliminate harmful tension inside the glass and prevent new stress from being generated.
