Abstract

The invention discloses a tempering method of washing machine panel glass. The method comprises the following steps: (1) preparing a pretreatment solution; (2) pre-treating; (3) tempering; (4) cooling. The tempering method is simple, and is convenient to operate; the ion exchange speed is improved by the pretreatment solution; the tempering method is safe and pollution-free; meanwhile, the temperature resistance of the glass is improved by adopting heating in two stages; the impact resistance of the glass is improved by cooling in two stages; the self-explosion probability of the glass is reduced.

Description

technical field [0001] The invention relates to a method for tempering the panel glass of a washing machine, and belongs to the technical field of glass processing. Background technique [0002] Tempered glass has been widely used due to its advantages such as high mechanical strength, excellent thermal shock resistance, and good safety. At present, tempered glass is divided into physical tempering and chemical tempering; the preparation process of physical tempering takes a long time, and the surface compressive stress layer is relatively thin. The chemical tempering technology changes the structure of the glass surface through ion exchange to generate stress on the glass surface to achieve the effect of glass strengthening. However, the current chemical tempering technology has the problem of not being environmentally friendly, and it takes a long time. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a m...
