Surface treatment of glass tea pot products
1. Reasons for glass tea pot manufacturers to do surface treatment of glass tea pot products
Change the chemical stability of the product surface and eliminate the surface damage of glass tea pot products to achieve the purpose of enhancement. The most important way to achieve this purpose is to add coatings during the production process, chemical strengthening, physical strengthening, surface acid treatment, plastic coating, etc.
2. The coating of glass tea pot products should be hot-coated after production and before annealing.
When the forming thickness glass is slowly cooled to 450--600 degrees, the metal coating agent is sprayed on the surface of the container to form a protective film of a certain thickness and increase the surface strength by 30%, so that the glass bottle can be In order to improve the mechanical strength and thermal stability of glass bottles and jars, we need to use cold air strengthening. The cold air strengthening treatment method is as follows.
3. After the glass tea pot products are released from the bottle making machine, they should be sent to the horse boiler immediately.
It is evenly heated to the softening temperature of the glass, and then sent to the tempering chamber, and the glass tea pot products are sprayed with cold air through a porous nozzle to quickly cool the glass bottle. The hardening of the glass bottle is caused by the sudden shrinkage of the surface.
