Galvanized tanks for sale, alength and width: 3.26 * 1.6 * 1.2 。Total 6 squares, 1 length and width: 1 * 1 * 1.5 Total 1.5 square, 3 thick board, the middle There are partitions, in July last year to buy a new low-cost treatment, two big cans almost four hundred and fifty pounds, want to find a car to pull I have a forklift can be loaded to you.
Hot-dip galvanized tank, also known as hot-dip galvanized tank. Its products are cold-formed square steel as the main material, after processing welding connection components, through the pickling rust treatment, and then into the zinc solution pool soak, the zinc liquid fusion on the steel surface, the formation of zinc-iron compound protective layer, so as to achieve Long-term anti-corrosion effect.
How to produce galvanized tank?
1 hot-dip galvanizing
To control the zinc liquid temperature, dip time and the workpiece from the zinc liquid leads to the speed. Lead the speed is generally 1.5 m / min. Temperature is too low, zinc liquid fluidity is poor, thick and uneven coating, easy to produce sagging, the appearance of poor quality; high temperature, zinc liquid fluidity, zinc liquid easily from the workpiece to reduce sagging and wrinkled skin phenomenon, adhesion Strong, the appearance is good, the appearance is good, the production efficiency is high; But the temperature is excessively high, the work piece and the zinc pot iron loss is serious, produces the massive zinc dregs, affects the zinc dip layer quality and is easy to cause the chromatic aberration to cause the surface color to be unsightly, Zinc layer thickness depends on the zinc liquid temperature, zinc immersion time, steel material and zinc liquid composition.
The purpose is to improve the surface corrosion resistance of the workpiece to reduce or extend the appearance of white rust to keep the coating has a good appearance. Most of the use of chromate passivation, such as Na2Cr2O7 80 ~ 100g / L, sulfuric acid 3 ~ 4ml / L, but this passivation solution seriously affected the environment, and our company used chromium-free passivation.
Coating appearance of bright, detailed, no sag, wrinkled skin phenomenon. Thickness testing can be used coating thickness, the method is relatively simple. The thickness of the coating can also be calculated by the zinc deposition amount.
