perforated aluminium foilThe iron is clean and clean, and then solvent treatment, after drying immersed in zinc liquid, iron and molten zinc reaction to produce an alloyed zinc layer, the process is: degreasing – washing – pickling – assisted plating – drying – hot dip galvanizing – separation – cooling passivation. The thickness of the alloy layer of hot plating wire mainly depends on the chemical composition of the steel silicon content, the size of the steel cross-sectional area, the roughness of the steel surface, the temperature of the zinc pot, the time of dipping zinc, cooling speed, cold rolling deformation, etc.

perforated aluminium foilGalvanized wire in acid, alkali, sodium chloride aqueous solution of poor corrosion resistance, in the atmosphere containing carbon dioxide and hydrogen sulfide, as well as Marine atmosphere is not corrosion resistance. In high temperature and high humidity air and containing organic acid atmosphere is small, galvanized layer is also easy to be corroded. Galvanized wire and general wire is very different, general wire is cheap, and because the iron is not very stable, easy to rust in the wet place, so the stability is not very good, the life is not very long.

Cold galvanizing is also called electric galvanizing. It is the use of electrolytic equipment to remove oil, pickling, and then put the pipe into the solution of zinc salt, and connect the anode of the electrolytic equipment, place zinc plate on the opposite side of the pipe, and connect the positive pole of the electrolytic equipment to the power supply. A layer of zinc is deposited on the pipe fitting by directional movement of an electric current from the positive pole to the negative pole. Cold plated pipe fitting is processed before galvanizing.

Cotton is a plant that loves warmer weather and it takes several months for it to produce the fluffy cotton balls that we all know. After the plants are harvested, they are defoliated and send to the cotton gin. There, the cotton fibers are combed — this is done for cleaning and fiber straightening purposes — and then spun into yarn.
