Embodiment Construction

[0027] The present invention is described below in conjunction with specific embodiment:

[0028] A kind of production technology of painted back carving crystal glass, comprises the following steps:

[0029] first step:

[0030] Manufacture of molds: First, use laser engraving machines to engrave pre-designed painted patterns on metal molds, and then use methods such as back carving, round carving, and embossing to refine the details of the mold patterns.

[0031] Step two:

[0032] Mixing and stirring: Use a superfine pulverizer to crush the glass frit into 10 to 700 meshes, and then use a mixer to stir and mix the above glass into powder; the glass frit preferably has the following components in weight percentage: SiO 2 :62%, Na 2 CO 3 :23.2%, NaNO 3 :6%, Na 2 B 4 o 7 10H 2 O: 2%, BaCO 3 :5%, Li 2 CO 3 :0.8%, CeO 2 :1%.

[0033]

[0034] third step:

[0035] Powder drying: use natural drying and electric drying to dry the powder until the water content is ...

Abstract

The invention provides a production process of colorfully-painted and back-engraved crystal glass. The production process is realized by sequential steps of prefabricating a colorfully-painted pattern mould, mixing and agitating, drying material powder, granulating, heating and fusing, dropping materials into the mould, cooling and de-molding, annealing, carrying out cold machining and the like. According to the production process, a laser precision engraving machine is used for engraving patterns on a metal mould; then fused glass liquid is processed by the process of dropping the materials into the mould, cooling and de-molding, and annealing to obtain a semi-finished product; and then, the cold machining is carried out and manners of back engraving, circular engraving, floating engraving and the like are utilized to machine back loss of a product and fuzzy pattern details in a previous production process to enable to the patterns to be vivid. When paint is used for gradually coloring the product layer by layer, an outer layer needs to be colored under the precondition that the inner layer is completely dried. After the coloring is finished, the product is dried to guarantee the durability of colorfully-painted colors. Compared with an existing product, the product prepared by the production process disclosed by the invention has the characteristics of long preservation time, bright pattern colors and capability of vividly presenting three-dimensional patterns.

Description

technical field [0001] The invention relates to a glass production process, in particular to a production process of painted back-carved crystal glass. Background technique [0002] At present, most similar products on the market use thermal transfer printing and laser engraving technology. The principle of thermal transfer printing technology is to transfer photos into an adhesive film, and fix the adhesive film on the product surface through thermal processing; the principle of laser internal engraving technology is Using the principle of light interference, two laser beams are used to inject into the product from different positions and angles, and a large amount of heat is generated at the interference point to melt the glass at the point into tiny cavities, and many cavities can form a pattern. [0003] Handicrafts made with thermal transfer printing technology can show colorful patterns on the surface of the product, but they will fade after being stored for more than ...
