The first is the transparency of the glass bottle. The transparency of the glass bottle can give customers a clean visual impression. The hardness quality of the glass bottle can strengthen the self-confidence of customers. Many manufacturers improve the quality of glass containers through cold and thermal spraying, and the inner and outer walls of glass bottles.
Another way to increase the hardness of the container by adding powder to the wall heating is to reduce the surface and internal cracks of the glass bottle, thereby increasing the hardness of the glass bottle and improving the quality of production. The detailed principle of this powder spraying method is: when the glass bottle comes out of the forming mold of the bottle making machine, the multi-particle ammonium sulfate powder is put into the bottle through the automatic powder spraying machine, and then annealed in the annealing kiln.
The automatic powder feeder is equipped with a funnel, powder storage tube and powder nozzle. The piston rod with the feed hole can slide repeatedly to a certain extent. The powder in the storage tube can be quantitatively fed into the feed nozzle and fall into the glass bottle. Because the powder is evenly dispersed in the glass bottle, the bottom of the bottle absorbs heat evenly, which reduces the occurrence of cracks and improves the quality of disposal. After the glass bottle manufacturer returned for the second time, the glass container rarely cracked, and the hardness and output could be improved accordingly.
