Surface Treatment Of Glass Jars

1. Reasons for glass jar surface treatment by glass jar manufacturers

Change the chemical stability of the product surface and eliminate the damage of the glass bottle surface to achieve the purpose of strengthening. The main way to achieve this goal is to add paint during the manufacturing process, chemical strengthening, physical strengthening, surface acid treatment, plastic coating Layers and other methods.

2. The hot coating of the glass jar is carried out after production and before annealing

When the formed 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, increasing the surface strength by 30%, so that the glass bottle can pass through To withstand a long time of washing and washing, in order to improve the mechanical strength and thermal stability of the glass bottle can, we need to use cold air strengthening, cold air strengthening treatment method is as follows.

3. The glass jar should be sent to the horse boiling furnace immediately after being demolded by the bottle making machine

Evenly heated to the softening temperature of the glass. After being fed into the tempering room, a porous nozzle is used to spray cold air into the glass bottle to quickly cool the glass bottle. Liquid can also be used as a cooling medium for sudden cooling. Sudden contraction to produce the hardness of the glass jar.
