Abstract

The invention discloses a production process of a glass cover plate of a washing machine. Comprising the following steps: (1) melting raw materials: uniformly mixing waste glass, quartz sand, borax, limestone and sodium carbonate, and then heating and melting to obtain molten liquid; (2) molding and cutting: cooling the molten liquid to obtain molded glass, and cutting the molded glass into the required size; (3) annealing: placing the formed glass in an annealing furnace, heating to 850-900 DEG C, keeping for 2-3 hours, then rapidly cooling to 560-650 DEG C, keeping for 1-1.5 hours, and then rapidly cooling to room temperature to obtain finished glass; and (4) post-treatment: printing the finished glass for many times to finally obtain the glass cover plate. According to the production process, the waste glass is adopted as the raw material, the raw material cost is saved, the waste glass, the quartz sand, the borax, the limestone and the sodium carbonate serve as the raw materials, annealing operation is performed after melting and cutting, the strength of the glass can be improved, and the glass is suitable for being used as the cover plate.

Description

technical field [0001] The invention relates to a production process of a glass cover plate of a washing machine, and belongs to the technical field of glass production. Background technique [0002] In home appliances such as electric cookers, refrigerators, washing machines or air conditioners, there are display arrangements including various layers, and the display arrangements are based on display technology layers, which are generally made of glass. [0003] With the improvement of people's living standards and the development of the home improvement market, people's aesthetic concepts are increasingly strengthened, and the requirements for the appearance of glass are getting higher and higher, so the application of printing technology in glass products is also increasingly widespread. Ink is the main material that can effectively enhance the appearance of glass products. The thickness of the glass cover of the washing machine is generally not too thick, which will aff...
