Hot-dip galvanized sheet is usually called hot-dip galvanized steel sheet, which is to immerse steel, stainless steel, cast iron and other metals in a molten zinc solution at about 500°C to attach a zinc layer to the surface of the steel sheet to achieve the purpose of anti-corrosion. The hot-dip galvanized steel sheet has good coverage, and the galvanized layer is dense and not easy to fall off.
Electrolytic plate is also called electro-galvanized plate. It uses electrolytic equipment to degrease and pickle the pipe fittings into a solution of zinc salt, and connect the negative electrode of the electrolytic equipment. Place a galvanized plate on the opposite side of the pipe and connect it to the electrolytic device. The positive pole of the device is powered on, and the directional movement of the current from the positive pole to the negative pole will deposit a layer of zinc on the steel plate. This kind of cold galvanized steel sheet has good workability, but the coating is thinner and the corrosion resistance is not as good as that of hot-dip galvanized steel.
The specific difference between hot-dip galvanized sheet and electrolytic sheet:
1. The galvanized zinc layer is different, the zinc layer of electrolytic plate is thinner, and the zinc layer of hot-dip galvanized plate is thicker.
2. The appearance is different, the appearance of the electrolytic plate is smooth and bright, and the appearance of the hot-dip galvanized plate is rough and poor in gloss.
3. Different application occasions. Electrolytic plates are used for general anti-corrosion occasions in various industries, and hot-dip galvanized plates are used for outdoor occasions that require strong corrosion resistance.
4. The adhesion of the zinc layer is different, and the adhesion of the electrolytic plate is not as good as that of the hot-dip galvanized plate.
5. Different anti-corrosion protection ability, electrolytic plate is not as good as hot-dip galvanized plate.
