How to reduce the number of glass-lined equipment

During the manufacture of glass-lined equipment, a lot of internal stress will be produced because of the drum, stamping and welding. These stresses should be eliminated by heat treatment before the bottom glaze is fired, which will reduce the times of firing, ensure the production efficiency of glass-lined equipment.

1, glass-lined equipment porcelain layer thickness is 0.8-2mm, the number of times should be in the enamel firing 5-7 times. There are many enterprises in production to reduce the number of enamel firing, increase the thickness of each spray glaze.

2. The stress of the equipment in the process of manufacture should be released by means of annealing, and the finished equipment should be left for less than 15 days after the equipment has been enameled, and the finished equipment should not explode porcelain before leaving the factory.

3. In order to make up for the defects of pinhole and explosion of porcelain layer in the process of making, the equipment flange is seriously deformed.

In addition, hydrogen is produced when acid is introduced into the jacket, when acid droplets are scattered on the cover of the kettle or when the heat conduction medium is acidic, and some hydrogen atoms diffuse to the holes in the metal, where they combine to form hydrogen molecules, this will make glass-lined equipment enamel thinning, can not be used to reduce the number of enamel to improve efficiency.
