Glass bottle production of raw materials which contain several

The batch of glass bottle container glass raw material, and chemical composition individual consists of 7 ~ 12 kinds of raw materials. Important is quartz sand, soda ash, limestone, dolomite, feldspar, borax, lead and barium compounds, etc. In addition, there are clarifying agent, colorant, decoloring agent, opacifying agent support materials. Coarse particle quartz difficult to complete melting; Particles in detail and in the process of melted scums and dust easily, affect the melting, easy infarction furnace regenerator. Appropriate size to zero. 25 ~ 0. 5mm。

for dominating the waste glass, the individual also intervene in broken glass, who is 20 ~ 60%, the highest can amount to 90%. The chemical composition of glass bottle glass, according to its operation request, molding, molding speed, material selection and process characteristics and differences. The most soda lime silicate glass bottles. An essential ingredient of the soda lime silicate glass of SiO2 and Na2O and CaO.

introduction of Al2O3 and MgO style, appropriate can landing glass crystallization bias, strengthen glass chemical invariance and mechanical strength, improved glass forming performance. Greatly all countries in the world of the soda lime glass bottles of chemicals for: SiO270 ~ 74%, CaO and MgO10 ~ 14%, Na2O and K2O13 ~ 16%, Al2O31. 5 ~ 2. 5%. Produce colorless glass bottles, quartz sand of Fe2O3 content is very low. In the popular soda lime glass, add the Cr2O3 and Fe2O3, a green green glass, add sulfur - Carbon or MnO2 and Fe2O3, brown glass. Colourful take medicine bottles, the request has higher chemistry invariability, made of borosilicate glass. Senior cosmetic bottle, often operating with lead, barium or zinc crystal glass production, some is opacified glass, individual with fluoride as opacifying agent.
