Problems solved by technology

[0005] The purpose of the present invention is to provide a washing machine panel glass preparation method to solve the problem that the edge of the existing washing machine panel glass proposed in the above background technology is mostly polished by a grinder, which cannot effectively ensure the size of the glass, and after grinding The corners of the glass are not smooth enough to ensure the effect of the follow-up process. Most of the existing washing machine panel glass has undergone a heating and cooling process, resulting in insufficient temperature resistance and impact resistance of the glass, and the ink on the washing machine panel glass is mostly used Traditional printing ink, the ink will leak after a long time, which hinders the appearance

Embodiment 1

[0020] The washing machine panel glass preparation method comprises the following steps:

[0021] S1: Cutting and grinding: Cut the glass to the required size and use a laser grinder to grind the surroundings of the glass to smooth the surroundings of the glass. Laser grinding can effectively guarantee the size of the glass, and the edges and corners after grinding are smooth. Can effectively guarantee the follow-up process;

[0022] S2: Three-stage heating: Put the cut and polished glass into the tempering furnace for three-stage high-temperature tempering. The first stage is heated to 120°C and kept for 30 minutes, and the second stage is heated to 200°C. Keep it for 20 minutes, heat up to 260 degrees Celsius in the third stage, and keep it for 10 minutes;

[0023] S3: Three-stage cooling: Take out the glass after three-stage high-temperature tempering and put it into the cooling furnace for three-stage cooling. The first stage rapidly lowers the temperature to 200°C and ke...

[0026] The washing machine panel glass preparation method comprises the following steps:

[0027] S1: Cutting and grinding: Cut the glass to the required size and use a laser grinder to grind the surroundings of the glass to smooth the surroundings of the glass. Laser grinding can effectively guarantee the size of the glass, and the edges and corners after grinding are smooth. Can effectively guarantee the follow-up process;

[0028] S2: Three-stage heating: Put the cut and polished glass into the tempering furnace for three-stage high-temperature tempering. The first stage is heated to 160°C and kept for 35 minutes, and the second stage is heated to 220°C. Keep it for 23 minutes, heat up to 280 degrees Celsius in the third stage, and keep it for 13 minutes;

[0029] S3: Three-stage cooling: Take out the glass after three-stage high-temperature tempering and put it into the cooling furnace for three-stage cooling. The first stage rapidly lowers the temperature to 240°C and ke...

[0032] The washing machine panel glass preparation method comprises the following steps:

[0033] S1: Cutting and grinding: Cut the glass to the required size and use a laser grinder to grind the surroundings of the glass to smooth the surroundings of the glass. Laser grinding can effectively guarantee the size of the glass, and the edges and corners after grinding are smooth. Can effectively guarantee the follow-up process;

[0034] S2: Three-stage heating: Put the cut and polished glass into a tempering furnace for three-stage high-temperature tempering. The first stage is heated to 180°C and kept for 40 minutes, and the second stage is heated to 240°C. Keep it for 25 minutes, heat up to 300 degrees Celsius in the third stage, and keep it for 15 minutes;

[0035] S3: Three-stage cooling: Take out the glass after three-stage high-temperature tempering and put it into the cooling furnace for three-stage cooling. The first stage rapidly lowers the temperature to 260°C and keep...

Abstract

The invention discloses a method for preparing panel glass of a washing machine in the technical field of household appliances. The method comprises the steps of cutting and polishing, wherein glass is cut into a required size, and the periphery of the glass is polished by a laser polishing machine to be smooth; three-stage heating, wherein the cut and polished glass is put into a tempering furnace for three-stage high-temperature tempering. According to the method, the size of the glass can be effectively guaranteed through laser polishing, the polished corners are smooth, and the subsequentprocess can be effectively guaranteed; through three-stage heating and cooling, the temperature resistance of the glass is effectively improved, and the impact resistance of the glass is improved; byadding polyethylene resin, N-diphenyl-p-phenylenediamine and 2-hydroxybenzophenone to ink, the low temperature resistance, water resistance and acid resistance, acidity and alkalinity, oxidation resistance and light resistance of the ink are effectively improved, and the service life of the ink is prolonged.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a method for preparing panel glass of a washing machine. Background technique [0002] Home appliance is the abbreviation of household appliances. In a narrow sense, electrical appliances refer to the load on the circuit and the equipment used to control, adjust or protect circuits, motors, etc., such as speakers, switches, rheostats, fuses, etc. Electrical appliances in a broad sense refer to products that use electrical components to perform work. Usually they use electricity as an energy source. Foreign countries usually divide home appliances into 4 categories: white home appliances, black home appliances, beige home appliances and emerging green home appliances. White goods refer to products that can replace people's housework, including washing machines, refrigerators, etc., or products that provide people with a higher quality of living environment, such as air c...
