Glazed glass

Glazed glass refers to the application of a layer of colored and fusible glaze on the surface of glass cut to a certain size, which is then sintered, annealed, or tempered to firmly bond the glaze layer with the glass, resulting in a glass with beautiful colors or patterns. It is generally made of flat glass as the substrate. The characteristics are: exquisite patterns, non fading, non fading, easy to clean, and can be made according to user requirements or artistic design patterns.

Glazed glass has good chemical stability and decorative properties, and is widely used for indoor decorative layers, as well as decorative layers in general building foyers and staircases, and exterior decorative layers，Glass product   .



Colorful fusible glaze

Glazed glass refers to a glass with beautiful colors or patterns made by applying a layer of colored and fusible glaze on the surface of a cut glass of a certain size, and processing it through sintering, annealing, or tempering to firmly bond the glaze layer with the glass



concept

Glazed glass is made by coating a layer of colored and fusible colored glaze on the surface of the glass, heating it until the glaze melts, firmly bonding the glaze layer with the glass, and annealing or tempering treatment. It has good chemical stability and decorative properties, and is suitable for exterior wall finishes of buildings.

Production of Glass Glaze

The production of glazed glass includes processes such as the production of colored glaze, glazing, drying, heating, quenching or annealing, and cooling.

production

The production of glass colored glaze consists of two basic materials: base glaze and pigment, which are powders made from fusible glass frits; Pigment is an inorganic coloring substance, which can be a Inorganic compound or several Inorganic compound, and is made by grinding, mixing, sintering and then grinding into powder in a certain proportion.

(1) Base glaze

The function of base glaze is to highly disperse inorganic pigments and melt them on the surface of the glass substrate at a lower temperature, dissolving them with the substrate to form a whole; When the base glaze melts, inorganic pigments with strong coloring ability dye it into colored glass, which combines with the glass substrate to form a colorful glazed glass as a whole.

The process performance requirements of base glaze: the melting temperature is low and can melt on the surface of the glass substrate before it softens; It has good chemical stability and luster, and does not react with inorganic pigments, neither causing changes in the color of the inorganic pigments themselves; The expansion coefficient is very close to that of the glass substrate, and the glaze does not crack or shrink when the temperature changes.

(2) Pigment

Pigment is a type of metal oxide or compound, which can also be made by grinding, mixing, sintering, washing, filtering, drying, and grinding several metal oxides or compounds in a certain ratio to form fine powder.

The sintering temperature and time of various colors of pigments, including metal oxides and mild metals, vary depending on the pigments used.

The dispersion of pigments during use is closely related to their particle size. The smaller the particle size, the greater the dispersion (usually less than 5 particles) ц m)
