Which is better for cold galvanizing and electric heating zinc boilers?


Hot-dip galvanizing is a kind of technology which immerses the rust-removing steel into the molten zinc solution at about 500 C, so that the surface of the steel component is coated with zinc to achieve the purpose of corrosion protection. It is mainly used in the metal structure facilities of various industries. The galvanizing pot is a kind of technology which carries out the corrosion protection treatment of the surface of the workpiece by electrochemical principle. Cold galvanizing and hot-dip galvanizing as effective metal anticorrosive methods, which is good? The zinc pot manufacturer tells you:


Hot-dip galvanizing first pickles the steel tube, in order to remove iron oxide on the surface of the steel tube, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot-dip bath. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.


Cold galvanizing is galvanizing, the amount of galvanizing is very small, only 10-50g/m2, its corrosion resistance than hot-dip galvanized pipe is much different.


Many formal galvanized pipe manufacturers, in order to ensure quality, mostly do not use cold galvanizing, and the galvanizing pot manufacturers know that although the price of cold galvanizing is cheaper than hot galvanizing, but only those small-scale, obsolete equipment of small enterprises using cold galvanizing. Hot galvanizing has good effect and long life.


Zinc pot is a kind of equipment used for anticorrosion. It is usually made up of electric heating zinc boiler. Internal heating ceramic galvanizing pot is a kind of zinc pot with long service life and high processing efficiency, which can realize automation. It is usually made up of three parts: protective heater, industrial ceramic material pot and automatic temperature control system. Its advantages are:


1. the processing efficiency is high, the anticorrosive effect is good.


2. design science, can achieve intelligent


3. stable work, convenient maintenance and operation.


4., it has a good appearance and long life.
