Description
Technical Field
The invention belongs to the technical field of glass product preparation, and particularly relates to a method for improving mechanical properties of a glass surface.
Background
Glass is a commonly used building material and decorative material. The glass mainly becomes silica, and theoretically, its mechanical strength such as breaking strength should be high, but it is not high due to microcracks inside the glass and local component non-uniformity, and has only ten and several MPa. Obviously, how to improve the mechanical strength of glass is a technical problem to be solved urgently.
The conventional reinforcing method in the prior art has no obvious reinforcing effect due to the requirements of the shape and the size of the glass product.
Disclosure of Invention
The invention aims to provide a method for improving the mechanical property of the surface of glass, so as to improve the mechanical property of the surface of a glass product and facilitate industrial production.
A method for improving the mechanical property of a glass surface comprises the following steps:
(5) cleaning and drying the glass product;
(6) low-temperature enhancement treatment;
(7) performing high-temperature reinforcement treatment;
(8) and cooling, cleaning, drying and detecting to obtain a finished product.
The step (1) comprises the following steps: cutting and edging the glass product, sending the glass product into a pickling tank, soaking the glass product in a hydrofluoric acid solution for 2-3 hours, taking out the glass product, and cleaning the glass product.
And the step (2) comprises the steps of preheating the glass to 300 ℃, then feeding the glass into the potassium nitrate molten salt, and exchanging ions in the surface of the glass with ions in the molten salt, wherein the temperature of the potassium nitrate molten salt is 475 ℃.
And the step (3) comprises the steps of taking out the glass, heating to 800 ℃, and then sending the glass into the potassium chloride molten salt for continuous ion exchange.
Cesium ion metal salts may also be added in the step (3).
The invention has the beneficial effects that: the invention further optimizes the surface property improving process of the glass, and the surface polishing of the glass can quickly eliminate the surface defects of the glass, so that the surface of the glass is smooth. The glass has good thermal stability, and the product is not easy to deform and is not limited by the thickness and the geometric shape of the glass. Through the treatment process, the breaking strength can be improved by more than 15 times, and the impact strength is 10 times that before exchange. And simultaneously, the glass product has good fracture characteristics, thermal stability and chemical stability.
