Description

Surface treatment method for glass product and glass product

Technical Field

The invention belongs to the technical field of glass surface treatment, and particularly relates to a surface treatment method of a glass product and the glass product.

Background

Because the glass has the characteristics of higher strength, hardness, wear resistance, good corrosion resistance and the like, the glass serving as a component is widely applied to the fields of buildings, daily use, medical treatment, chemistry, electronics and instruments. Along with the development of society and the improvement of living standard, people have higher and higher requirements on the modeling and decoration effect of glass, and the environment protection, energy conservation, high efficiency and texture are new targets for the development of glass production industry. However, in the prior art, when the appearance or the surface of a product is treated, a paint spraying process is often adopted, and the paint is dispersed into uniform and fine fog drops by a spray gun by means of air pressure and is applied to the surface of an object to be coated.

The spray paint is one kind of artificial paint, is made of cellulose nitrate, resin, pigment, solvent and the like, is water-resistant and engine oil-resistant, and can be dried quickly; can be used for painting automobiles, airplanes, woodware, leather and the like. However, the substance has toxicity and has certain influence on the body, and the toxicity of spray paints of different brands is different due to different component contents; special care should be taken to ensure safety during use, avoiding inhalation and skin contact. If the paint is sprayed under the condition of no protection, the benzene concentration in the air of a working place is quite high, and the paint is extremely harmful to paint spraying workers. Chronic poisoning, leukopenia, thrombocytopenia, and bone marrow hemopoiesis disorder can be caused by long-term benzene exposure. In addition, the harm of the paint to human bodies can be generated by lung inhalation and can be absorbed through skin; the skin of a human body directly contacts with the paint, fat in the skin can be dissolved, and the skin is cracked and inflamed and enters the human body. Therefore, the paint spraying must be equipped with a protection arrangement, while the working time is limited (preferably not more than 30 minutes), and the working place must have good ventilation conditions; otherwise, the health of human body is affected, and leukemia is possibly suffered.

The existing paint spraying process has the advantages of poor environmental protection performance, influence on human health, potential safety hazard and higher requirements on environment and equipment, and the treated product is lack of texture and stereoscopic impression, has no color change and gradation, is monotonous and not rich in color, and ensures that the product flow is simplified and low-grade; meanwhile, some surface colors are not firm, easy to fade, wrinkle and the like, influence the product quality, have larger use limitation and cannot meet the requirements of consumers.
