Method for preparing milk glass bottle

Abstract

The invention discloses a method for preparing a milk glass bottle. The method for preparing the milk glass bottle is characterized by comprising the specific steps: preparing raw materials; examining the raw materials; weighing and dosing; mixing; lifting to a stock bin of a furnace end; smelting in a constant temperature electric furnace; moulding by using a line and row machine; moulding the bottleneck by a manual machine; annealing; and examining and packaging by taking mineral raw materials and chemical raw materials as main raw materials, wherein the mineral raw materials comprise 170g of quartz sands, 215g of feldspar, 10g of calcite and 11g of dolomite; the chemical raw materials comprise 12g of sodium nitrate, 53g of sodium fluosilicate, 58g of sodium carbonate and 3.3g of a clarifying agent.

Description

technical field [0001] The invention belongs to the technical field of inorganic materials, and in particular relates to a method for preparing opal glass bottles. Background technique [0002] Opalescent glass is an artificial glass material that produces an opacifying effect under the action of light scattering by tiny particles in fluoride. It is a white translucent glass containing highly dispersed crystals made of transparent liquid glass. Introduce some low-solubility opacifying agents such as fluoride, chloride, phosphate, sulfate, etc. into the batch material. These substances dissolve in the glass liquid at high temperature, and one or more tiny particles of crystals are precipitated when the temperature is lowered. Light entering its interior is scattered by these particles, creating an opalescent effect. The degree of opacification depends on the dispersion of precipitated substances and the difference in refractive index between them and the host glass. [0003...

AI Technical Summary

Problems solved by technology

Fluorite or sodium fluorosilicate is used as an opacifying agent, and fluorine-containing substances will volatilize during the glass melting process, especially when the flame furnace is used to produce opalescent glass, the volatilization rate can reach 6% to 10%, which seriously pollutes the environment and damages the environment. human health

Moreover, the health problems of fluorine-containing opal glass products when heated and used are also worrying. Fluorine is one of the harmful substances, and its usage should be limited

The addition of a large amount of oxides can have an opacification effect. However, when the amount is large, the glass will be difficult to melt and the cost will also increase.

At the same time, due to the limitation of the distribution ratio of raw materials and the preparation process, the milky white glass bottle prepared in the prior art cannot achieve a height of 26cm. It is easy to produce problems such as transparent materials, color locks, insufficient whiteness, brittle products with high glass stress, etc.
