Embodiment 1

[0030] Such as figure 1 Shown, a kind of porcelain white glass production technique comprises the steps:

[0031] (1) Determine the formula and prepare the batch materials:

[0032] The formula of porcelain white glass includes by weight percentage: 60% batch material, and 40% broken glass. The batch consists of the following components in parts by weight: 58 parts of quartz sand, 14.5 parts of soda ash, 10 parts of aluminum hydroxide, 9.5 parts of sodium fluorosilicate, 6 parts of fluorite, 1 part of Barium sulfate, 1 part of sodium nitrate, 2.4 parts of calcite, 0.6 part of compound clarifying agent.

[0033] The corresponding raw materials are put into the mixing machine according to the corresponding ratio in the porcelain white glass formula to make batch materials, and the batch materials are in powder form. It can control the uniformity of the batch material to ≥95%, and the water content is 4-6%, which is beneficial to enhance the appearance of the final glass produ...

Embodiment 2

[0040] A porcelain white glass production process, the difference from Example 1 is that the batch material is composed of the following components in parts by weight:

[0041] 56 parts of quartz sand, 15 parts of soda ash, 9.5 parts of aluminum hydroxide, 9 parts of sodium fluorosilicate, 7 parts of fluorite, 1 part of sodium nitrate, and 0.6 parts of composite clarifier.

[0042] Example 2

[0043] A porcelain white glass production process, the difference from Example 1 is that the batch material is composed of the following components in parts by weight:

[0044] 55 parts of quartz sand, 15.8 parts of soda ash, 9 parts of aluminum hydroxide, 10 parts of sodium fluorosilicate, 5.5 parts of fluorite, 0.5 parts of sodium nitrate, and 0.5 parts of composite clarifying agent.

[0045] It should be noted that: in the present invention, porcelain white cullet refers to fragments of porcelain white glass, and colorless cullet refers to fragments of colorless glass. In the presen...

Abstract

The invention relates to a porcelain white glass and a production technique thereof. The production technique comprises the following steps: (1) preparation of mixture; (2) melting: melting the mixture and glass cullet in a kiln; (3) forming: forming in a glass forming device; and (4) annealing: annealing in an annealing kiln. The porcelain white glass is prepared from the following raw materials in percentage by weight: 60-90% of mixture and 10-40% of glass cullet. The mixture comprises the following components in parts by weight: 50-60 parts of quartz sand, 13.5-16 parts of soda ash, 10-12 parts of aluminum hydroxide, 9-11 parts of sodium fluosilicate, 5-7 parts of fluorite, 0-1.5 parts of barium sulfate, 0.5-2 parts of sodium nitrate, 0-3 parts of calcite and 0.3-0.7 part of composite clarifier. The porcelain white glass with high-whiteness porcelain appearance effect can be obtained by finely regulating and controlling the raw material formula and technological parameters.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to opal glass and a production process thereof. Background technique [0002] Opal glass is a translucent milky white glass that looks like jade. It has obvious glass characteristics, and is generally used for lighting equipment and equipment that needs to pass through light without seeing objects, but it is not suitable for making glass products such as cosmetic bottles, wine bottles, and wine glasses that require high appearance. Contents of the invention [0003] The invention overcomes the disadvantages of the prior art, provides a porcelain white glass production process, and also provides a porcelain white glass produced by the production process. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a production process of porcelain white glass, which is characterized in that it comprises the following steps: [0005]...
