Application of borosilicate glass

Borosilicate glass is a kind of glass that can effectively reduce the expansion coefficient of the glass by changing the glass composition, effectively improve the light transmission performance and glass strength, the softening point temperature of the glass, and the thermal conductivity of the glass, making it suitable for optical glass, precision instrument glass, Lamp glass, daily-use glass and other fields have been widely used [2].

Pharmaceutical packaging glass

Pharmaceutical glass is a major branch of the pharmaceutical packaging industry. It requires glass to have high stability, better sealing, and strong mechanical properties to ensure the stability and safety of the drug during storage and transportation, and avoid drug deterioration and packaging. damage.

Ordinary glass has low mechanical strength and poor stability, and cannot fully meet the requirements of medical glass. Most borosilicate glass is used.

Utensils and Cookware Glass

In daily life, a variety of glassware penetrates people’s lives, and glassware and glass cookware are increasingly appearing in people’s lives. These glassware and cookware require glass with high transparency, bright colors, and rich luster. It has good thermal and chemical stability, high mechanical strength, and cookware requires good thermal shock resistance. Generally, it can be directly heated with an open flame above 150°C. Ordinary glass can't meet these requirements. Borosilicate glass This aspect shows its very high characteristics, making the output of borosilicate glass second only to flat glass and bottle glass and ranks third.

Instrument glass

Instrument glass refers to the glass used to manufacture chemical, biological and laboratory utensils, pipes and devices. The manufacturing process of glass instruments is complicated, the application conditions are harsh, and the application environment is changeable. The glass requires good chemical stability, good thermal stability, high mechanical strength, and good process performance. Borosilicate glass is the best choice for instrument glass. It has been widely used in culture and education, scientific research, chemical industry, medicine and health and various industrial production, as well as high-tech fields such as aerospace, laser, biological engineering, and nuclear engineering [3].

fire-proof glass

Borosilicate fireproof glass with excellent performance in the international fireproof glass market—Borosilicate 3.3 glass is one of the most excellent glasses in industrial mass production at present. The main technical indicators: softening point 845℃±10℃; expansion coefficient (4.0± 0.1) ×10-6/K; density 2.28±0.02g/cm3; thermal conductivity 1.2w/mK, it can be seen that its softening temperature is higher, and the expansion coefficient is only one-third of ordinary soda lime glass, so it has A brand-new fire-resistant glass with good high temperature resistance and thermal shock resistance to achieve the purpose of safety and fire protection. Its excellent performance makes it a real fireproof glass.

Glasses glasses and sight glasses

Borosilicate glass can be made into heterogeneous photochromic glass through complex production process, which can be widely used in ordinary discoloring eyes, automobile protective glass, laser protection, window materials of spacecraft, and switches of new instruments, mainly in boron Silicate glass has the characteristics of high light transmittance, high strength, and good impact resistance. In industry, glass sight glasses are widely used in pressure vessels and instruments such as pipelines, valves, cracking furnaces, and liquid storage tanks. This shows that the borosilicate glass has high strength, good corrosion resistance, and good compression performance.

Display glass

Liquid crystal display (LCD) has become the main display device of electronic equipment such as computers, and wall-mounted TVs are becoming more and more popular. The LCD display panel requires that the glass substrate must be high-quality, ultra-thin, and high-transmitting special glass. , And can be accurately stored on the glass sheet. With the development of glass processing technology, display glass will develop in the direction of large size and ultra-thin. These requirements can only be achieved through float technology. And these just show that borosilicate glass will be or will be widely used [1].

Photocell

At present, renewable energy mainly includes wind power, water power, solar energy, etc. Because the use of wind and water power is relatively restricted by geographical environment and weather conditions, it is not conducive to general promotion and use. As a kind of energy, solar energy is pollution-free, easy to use, and easy to use. People pay more and more attention to the advantages of not affecting the ecological balance of the earth, and the research work of photovoltaic cells is also being carried out. In 1839, Becqueral in France observed the photovoltaic effect in chemical cells for the first time. Photovoltaic effects have also been observed in the system. The existence of the photovoltaic effect makes the production of photovoltaic cells possible. In 1954, Chapin, Fuller, and Pearson used semiconductor silicon (Si) diffusion p-n junctions to make solar cells for the first time, and they were put into use on spacecraft in 1958.

Simply put, the production of photovoltaic cells uses a layer of substrate glass and a layer of cover glass. The substrate glass is required to withstand a considerable degree of thermal load (550~630°C), resist chemical corrosion, and meet mechanical strength requirements, etc. . The good thermal expansion and thermal stability of borosilicate glass can be matched with amorphous silicon wafers.
