When glass is melted, a small amount of glass colorant is added to obtain various colored glass. Copper (II) oxide or chromium oxide (III) produces green; Cobalt oxide (II) produces blue; Manganese dioxide produces purple; Tin dioxide or calcium fluoride produces milky white; Uranium compounds produce yellow-green fluorescence; Colloidal selenium production Red jade color; colloidal gold produces red, red violet, or blue; cuprous oxide produces red, green, or blue; ferrous compounds produce green, and when the amount is large, it is black; iron (III) compounds produce yellow. In the production of glass, since the raw material contains ferrous impurities, the glass is often green, and a small amount of manganese dioxide or selenium may be added to make it a colorless glass.
Screen printing of glass
Glass screen printing jewelry wholesale, is the use of screen printing plate, the use of glass glaze, decorative printing on glass products. Glass glaze is also called glass ink and glass printing material. It is a paste-like printing material that is mixed and stirred by coloring material and linking material. The coloring material consists of inorganic pigments and low-melting fluxes (lead glass powder); the linking material is commonly referred to as linoleum oil in the glass screen printing industry. After printing, the glass products are placed in a stove and fired at a temperature of 520 to 600° C. The glaze printed on the glass surface can be consolidated on the glass to form a colorful decorative pattern. If you use silk screen printing with other processing methods, you will get better results. For example, by polishing, engraving, etching, etc., the glass surface is processed before or after printing, and the printing effect can be doubled. Glass etching screen printing
For a long time, the etched decoration of glass products is to heat-coat the wax layer and other reinforcement materials on the glass surface as a resist layer. Then the patterns on the coating are etched with needles, knives, etc. to expose the glass surface, and then This part is etched with hydrogen fluoride. This process has continued to be used by manufacturers, but its processing methods are time-consuming, laborious, and inefficient. The silk screen etching process makes the etching and decoration of glass products simple, time-saving, and labor-saving. Glass etching screen printing, hot and cold printing two methods. Thermoplastic etching screen printing is the preparation of paraffin wax, asphalt, stearic acid and other adhesives, adding a small amount of anti-corrosion powder modulation anti-corrosion printing materials, through the hot-printed silk screen, according to the design of the pattern, the printing material scraped To the glass surface, the formation of a resist film. Part of the glass exposed on the resist film is a pattern that needs to be etched. Etching is performed with fluorfluoric acid. After etching, the resist printed on the glass is rinsed with boiling water. Glass stencil etching can also be performed using cold stamping methods. Anti-corrosion printing material can use special asphalt paint and anti-corrosion powder, and can also buy commercially available ink-resistant ink. After the printing is completed, the hydrofluoric acid corrosion can be performed until the resist film is completely dried. Hot stamping is suitable for the etching of continuous, tetragonal pattern patterns on two sides, and cold stamping is applied to the etching of individual patterns.
