1. Rotation speed: In the process of centrifugal pipe expansion, the rotation speed and pipe diameter determine the centrifugal force. When the pipe diameter is certain, the higher the rotation, the greater the centrifugal force. Under the action of centrifugal force, the larger the pipe diameter, the slower the rotation speed. Therefore, the speed used in the pipe expansion process should be based on the diameter of the glass tube
2. The wall thickness and the corresponding temperature are determined. In the process of electrothermal softening and air-pressure pipe expansion, the control of pipe diameter mainly relies on a set of sizing devices that rotate synchronously with the glass tube, which has a wider range of speed requirements.


The purpose of eliminating permanent stresses in the glass article and structural imbalances. Glass is a poor conductor of heat. After molding, the inner surface layer and the temperature difference in the cooling process there. When the inner surface layer solidification thick, but there is the temperature difference stress relaxation. When the surface layer cooled to room temperature, this temperature difference will appear. Inner continued cooling shrinkage, tensile stress hampered by the surface, while the surface compressive stress, is permanent. Size and distribution of permanent stresses caused by thermal processing of the product portions are not uniform, and 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. During annealing, heat the glass product or keep it to the annealing temperature after thermoforming, so that the original stress is relaxed and eliminated, and then slowly cooled to below the strain temperature. After the glass has completely entered the state of rigid body, the temperature difference between the inner and outer layers only produces temporary stress . Because certain performance and functional glasses (such as optical glass, thermometer glass) are within the transition temperature range, the huge viscosity makes the structure particles move slowly, so that its performance cannot reach the equilibrium state consistent with the temperature, and it will balance slowly during use. Produce performance changes, therefore, it must be kept at the annealing temperature for sufficient time

Belonging PYREX glass of borosilicate glass. Acid, water, corrosion resistance, thermal stability, chemical stability and good electrical properties, thus having chemical resistance, thermal shock resistance, good mechanical properties, temperature and other characteristics. Linear thermal expansion coefficient of borosilicate glass (also known as hard glass) was (3.3 ± 0.1) × 10-6 / K, so it was called "borosilicate glass 3.3." Is a special glass material having a low expansion, high temperature, high strength, high hardness, high light transmittance and high chemical stability. Because of their excellent properties, it is widely used in the field of solar energy, chemical, pharmaceutical packaging, electric light source. , Jewelry, and other industries.


principle


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.

Since its establishment, the four-star company has always adhered to the purpose of "dedicating itself to the development of pharmaceutical industry and ensuring the safety of people's medication", the business philosophy of "taking integrity as the foundation, survival by quality and development by innovation", and the quality policy of "scientific management, careful manufacturing, high-quality service and excellence". All employees work hard with one heart and one mind, In the fierce market competition, we overcome difficulties, forge ahead bravely, and continue to develop and grow.
