Tempered glass insulation light transmittance. The characteristics are stable, and various types have different characteristics due to the different use of sites, and the main uses are very wide. In the selection of tempered glass, in addition to paying attention to the price, but also deal with its type and characteristics have a certain grasp, make up for weaknesses, in order to find more suitable for the use of raw materials. We collect raw materials to write the article, to help you grasp what raw materials of glass bottle forming abrasives, and how to repair the abrasives for glass bottles?
Raw material of pig iron for glass bottle forming abrasives
The important failure methods of glass bottle forming die are: air oxidation (molting. Fall off. Small black dot). Chamfering and deformation. Phosphorous fall is an important method of glass bottle forming die fee. The prerequisite for damaging the service life of abrasive tools is the heat resistance of raw materials, that is, the oxidation resistance of raw materials at high temperatures. The ability to resist growth and development depends on the basic and post-calcined petroleum coke appearance in the tissue.
Add copper to pig iron. Chromium, tin and other elements can promote the conversion of metallographic structure, improve the compressive strength of pig iron, and thus improve the chamfering resistance of abrasive tools. Professional ability to resist wear and tear. Silicon. Aluminum and other elements, resulting in high density Si02 and A1203 surface air oxide film, thereby improving the surface antioxidant professional ability of abrasive tools.
New pig iron raw materials for glass bottles include low-tin pig iron. Copper chromium pig iron. Medium silicon thin. Medium silicon molybdenum soil. Low tin vermicular iron. Low aluminum creep iron, etc. Comparison of the service life of glass bottle mold materials: the service life of HT200 abrasive tools is lower, and the low aluminum creep iron is higher, and the distance is about 5 times.
The maintenance of glass bottle abrasives is important to follow the following steps
1. Get rid of the de-film agent in the mold. High temperature air oxide layer and other attachments;
2. The injured part of the grinding tool is detected;
3. Polish and polish the harmful parts. Repair;
4. Pay attention to the line when repairing. Repair of surfaces, notches, etc. Line is not due to arc; The surface can be vertical; The notch should be smooth;
5. For polishing and polishing after repair, it is recommended to use a fully automatic polishing machine. If the grinding tool is not closed, use a polishing ball to polish and polish.
