Cosmetic glass manufacturers introduced soda lime glass in the end is good
As daily glass,soda lime glassThe cup is relatively safe and will not cause adverse effects on the body. Soda-lime glass is silicate glass, which has good chemical stability and thermal stability. In the process of daily use, it will not cause adverse effects on the body, and the stability is relatively good.
Soda lime glass is mainly composed of silica, calcium oxide and sodium oxide. Such as commonly used flat glass, bottles, cans, bulbs, etc. Sodium oxide can increase the thermal expansion coefficient of glass, reduce the thermal stability, chemical structure stability and mechanical strength of glass, but the proportion can not be too much, generally not more than 18%. Sodium oxide is generally introduced as a pure alkali in the production of glass.
The main function of calcium oxide in glass is to improve the chemical stability and mechanical strength of the glass, but when the calcium content is high, it will increase the tendency of the glass to devitrification and make the glass brittle.
The daily necessities produced with it are relatively safe products on the market at present. When using glass cups, we need to pay attention to the fact that the glass is relatively hard and brittle, the strength is not very high, and the thermal conductivity is relatively poor, so when using soda-lime glass cups, pour a little hot water first, then rinse the bottle, and then pour hot water.
Above iscosmetic glassThe manufacturer introduces all the contents of soda lime glass. I hope you can have a further understanding of it after reading it. If there is anything else that is not clear, please come to consult us.
Chengde Huafu Glass Technology Engineering Co., Ltd. has more than 60 years of glass production history and more than 20 years of glass electric melting experience. It is a scientific and technological enterprise in the field of glass electric melting. The company mainly produces products such as glass electric melting furnace, bottle glass electric melting furnace, glass furnace glass melting furnace,soda lime glassGlass electric melting furnace, high borosilicate glass,cosmetic glassWait. If you have this requirement, welcome to come to consult, we look forward to cooperating with you.
Because the high borosilicate glass has the characteristics of low expansion rate, high temperature resistance and high strength, the glass is roasted at 630℃. so this type of glass is widely used. What are the advantages of high borosilicate glass compared with ordinary glass? Let me introduce to you briefly!
Because the low coefficient of thermal expansion, it is not easy for high borosilicate glass to crack under harsh temperature like soda lime glass. Therefore, many industries regard this kind of glass as a good choice for producing products. What other advantages does it have? Let's introduce it to you briefly.
In order to improve the service life of the feeder belt and its frame, and at the same time improve the uniformity of feeding, the Delta version.The YS type feeder is upgraded and adjusted as follows.
Phenomenon: During on-site debugging, such situations often occur: the same voltage and current are inconsistent when measured by different instruments, with deviations as small as 20~30 and as many as 60~70. So which is more accurate in measuring electricity meter, pointer meter or multimeter?
Because of its good chemical stability, bottle glass has no pollution to the contents; because of air tightness and high temperature resistance, a certain mechanical strength and reliable use; because of transparent or colorful and help to improve the grade of goods. Therefore, bottle glass is mainly used for product packaging in food, alcohol, beverage, medicine and other industries.
The air-cooling system of the pool wall of the electric melting furnace may not be of any use in the early stage of the furnace, but it shows its function in the later stage.
