Introduction to the raw materials of glass bottles

Various materials used to prepare glass batches are collectively referred to as glass raw materials. Roughly composed of 7-12 kinds, there are 4-6 kinds of main materials, such as quartz sand, limestone, feldspar, soda ash, boric acid, lead compounds, barium compounds, etc. According to the role of the introduced oxides in the glass structure, they can be divided It is the raw material of glass forming oxide, the raw material of intermediate oxide, and the raw material of network outer body oxide. According to the nature of the introduced oxide, it can be divided into the raw material of acidic oxide and the raw material of alkali metal oxide. Batch materials are the raw materials for glass to obtain certain necessary properties and accelerate the melting process. Although the amount is small, the effect is really important. These auxiliary materials are divided into clarifiers, fluxes, colorants, decolorants, opacifiers, and oxidizers. , Reducing agent, etc. Different formulations of the same raw material, different origins of the same raw material and different relevant index contents will all affect product quality and production costs. When the raw material cost disparity is small, it is difficult for the produced glass bottles to be significantly different when comparing the samples. The difference can only be seen in mass production.
