Problems solved by technology

[0005] ①Influence of glass quality defects
[0009] C. Defects such as scratches, cracks, and deep cracks on the glass surface due to the addition process or improper operation can easily cause stress concentration or self-explosion of the tempered glass
[0010] ② Stress distribution in tempered glass is uneven and offset
[0013] As mentioned above, no matter whether the tempered glass is subjected to external force or not, some small pits will be produced during use. The traditional solution is to replace these flawed tempered glass, so the cost is greatly increased

Embodiment Construction

[0027] The invention provides a shallow pit treatment method of tempered glass, the main steps of which are as follows:

[0028] Step 1: Clean the tempered glass shallow pit to be treated and the tempered glass around it; mainly use a softer brush to clean these parts, and its main function is to prevent other impurities from falling into the shallow pit during the repair process. make the repair fail. In this processing step, tools such as blowing up balloons with rubber can also be used.

[0029] Step 2: Use transparent adhesive tape to paste on the shallow pit and the tempered glass around it. The main purpose is to avoid further fragmentation near the shallow pit during the repair process.

[0030] Step 3: Use a pointed drill to drill through the transparent tape and turn it in the shallow pit. Its function is to eliminate the edges and corners in the shallow pit, so that the filling material can be fully filled into the shallow pit. When you're done, you can blow up the...

Abstract

The invention relates to a method for maintaining and repairing toughened glass, in particular to a method for treating shallow pits on toughened glass. The method comprises the following steps: cleaning the shadow pits of the toughened glass to be treated and the toughened glass around the shallow pits and adhering a transparent adhesive tape on the shallow pits and the toughed glass around the shallow pits; drilling through the transparent adhesive tape with a pointed cone and rotating the pointed cone in the shallow pits; vacuuming the shallow pits with a small vacuum pump and then filling transparent filling resin into the shallow pits; and after the primary solidification of the transparent filling resin, removing the vacuum pump and evenly wiping off the overflowing filling resin around the shallow pits with a small blade. The method does not require replacement of the toughened glass and can repair the shallow pits on the toughened glass effectively.

Description

technical field [0001] The invention relates to a maintenance and repair method for tempered glass, in particular to a shallow pit treatment method for tempered glass. Background technique [0002] Tempered glass is processed from ordinary flat glass or float glass. Ordinary flat glass requires selected products or first-class products; float glass requires superior products or first-class products. There are two processes for producing tempered glass: one is to process ordinary flat glass or float glass under specific process conditions by quenching method or air-cooling quenching method. The other is to process ordinary flat glass or float glass through ion exchange to change the composition of the glass surface to form a compressive stress layer on the glass surface. Tempered glass has the characteristics of high impact strength (4 to 5 times higher than ordinary flat glass), high bending strength (5 times higher than ordinary flat glass), good thermal stability, clean,...
