example 1

[0014] Example 1 Using waste white glass bottles as the base material, the oxide content of each component is as follows: SiO 2 67.0%, Al 2 o 3 7.5%, B 2 o 3 4.0%, CaO 1.5%, MgO 2.0%, Na 2 O 6.0%, K 2 O 4.0%, ZnO 1.5%, F - 5.0%, BaO 1.5%, each ingredient is crushed to 60 mesh and mixed, the batch is evenly mixed, and then put into an electric furnace to heat and melt. Take out the blow molding and evaluate its appearance and physical and chemical properties.

example 2

[0015] Example 2 uses waste white glass bottles as the base material, and the components are as follows: SiO 2 72.5%, Al 2 o 3 6.25%, B 2 o 3 3.1%, CaO 1.25%, MgO 1.75%, Na 2 O 5.0%, K 2 O 3.5%, ZnO 1.4%, F - 4.0%, BaO 1.25%, each component is crushed to 90 mesh and mixed, the batch is evenly mixed, and then put into an electric furnace for heating and melting, the maximum temperature of the furnace is 1500°C, each component in the batch is fully melted, homogenized and clarified, and then The samples were taken out and blown into molds, and their appearance and physical and chemical properties were evaluated.

example 3

[0016] Example 3 Using waste white glass bottles as the base material, the components are as follows: SiO 2 78%, Al 2 o 3 5%, B 2 o 3 2.2%, CaO 1.0%, MgO 1.5%, Na 2 O 4.0%, K 2 O 3.0%, ZnO 1.3%, F - 3.0%, BaO 1.0%, crush the ingredients to 120 mesh and mix, mix the batch evenly, and then put it into the electric furnace to heat and melt; The samples were taken out and blown into molds, and their appearance and physical and chemical properties were evaluated.

[0017] sample

[0018] It can be seen from the data listed in the above table that the indicators of each opalite porcelain glass sample are better than the porcelain vessels recognized as good quality in the market at present, and are equivalent to the high white porcelain glassware produced by expensive Corning and bow and arrow.

Abstract

The present invention discloses one kind of environment friendly heat resistant opal crystalline ceramic glass and its preparation process. The opal crystalline ceramic glass is prepared with base material, supplementary material and additive and through one electric smelting process at 1480-1520 deg.c. It consists of SiO2 67.0-78.0 wt%, Al2O3 5.0-7.5 wt%, CaO 1.0-1.5 wt%, MgO 1.5-2.0 wt%, Na2O 4.0-6.0 wt%, F- 3.0-5.0 wt%, ZnO 1.3-1.5 wt%, B2O3 2.2-4.0 wt%, BaO 1.0-1.5 wt%, and K2O 3.0-4.0 wt%. It has thermal expansion coefficient not higher than 7.0x10<-6>/ deg.c, Mohs hardness up to 6.5, thermal shock resisting temperature higher than 150 deg.c and high water resistance, and is ideal substitute for traditional porcelain.

Description

technical field [0001] The invention relates to opalite porcelain glass and its preparation process, in particular to an environment-friendly high heat-resistant opalite porcelain glass and its preparation process. Background technique [0002] It is reported that due to environmental protection requirements, the EU will gradually ban the production and import of porcelain products containing heavy metals in 2007. There have been various reports abroad on the use of milky white glass to produce glassware. At present, the more successful ones are Corning in the United States and Bow and Arrow in France. The milky white glassware developed by them can replace traditional porcelain, but they also have several major disadvantages such as high investment, high cost, and high price. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly high heat-resistant opalescent porcelain glass and its preparation process, to produce ch...
