Embodiment Construction

[0016] The specific implementation will be described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 Shown, the preparation method of colored glaze of the present invention, comprises following processing step:

[0018] Raw material selection: select ultra-clear glass scraps or optical glass scraps available in the market;

[0019] Raw material crushing: crush ultra-white glass scraps or optical glass scraps into irregular blocks with a diameter of 40mm-80mm;

[0020] Use 5%-15% acid solution (HCL, H2SO4 or HNO3) to remove raw material impurities, mainly to oxidize and remove the metal component iron in the raw material;

[0021] Rinse with pure water and dry for later use;

[0022] Sprinkle one or two sides of the washed and dried glass raw material with high-temperature pigment, that is, glaze;

[0023] Then place the glass block flat on the glass melting furnace, place the glass block at a thickness of 1mm per square meter, and place the g...

Abstract

The invention discloses a preparation method of glass, which comprises the technical steps of raw material selection, crushing, impurity eliminating, rinsing, drying, coloring matter splashing, putting, burning to 750 to 980 DEG C, annealing for cooling and cold manufacturing. The invention has no lead component during the preparation process, thereby avoiding from causing lead poisoning during manufacturing and using processes. The coloring matter flows in a high-temperature furnace to form a natural cloud-shaped design and a beautiful color. Air bubble can be produced inside of the product in low temperature, and the product has elegant appearance.

Description

technical field [0001] The invention relates to the technical field of decorative glass building materials, in particular to a preparation method of lead-free glazed glass. Background technique [0002] Glass products are a kind of traditional high-grade roofing and wall building decoration materials. At present, the raw material natural quartz sand of the traditional glass preparation method contains lead components. The problem with this preparation method is that the lead poisoning produced in the production process seriously endangers the health of workers and causes environmental pollution. In addition, the glass products manufactured by it also contain lead components, so they cannot be directly used to make daily necessities and dining containers. Contents of the invention [0003] The technical problem solved by the present invention is to overcome the defects of the prior art and provide a preparation method of colored glaze which does not contain lead in the pre...
