1. Principle different the principle of hot dip galvanizing is to invade steel components into the container containing galvanizing solution, so as to obtain the metal coating. Galvanizing is to put the processed ironware into the solution containing zinc salt after degreasing and pickling, and then apply the chemical principle to the zinc on the iron and steel devices through the electrolytic equipment.
2. The required equipment is different. Galvanizing requires electrolytic equipment, while hot galvanizing requires pickling equipment, bottom drawing annealing furnace or bell type annealing furnace.
3. The performance and advantages are different. Galvanizing is environmentally friendly because there are no solvents and diluents with high toxicity, which is very easy to protect the environment. Hot dip galvanizing is durable, durable and anticorrosive. Because its galvanized layer is mainly composed of a unique metal structure, it is very durable.
4. Different applications of galvanizing are mainly based on anti-corrosion coatings, which are developed in the direction of environmental protection. Hot dip galvanizing is mainly because it has a very good anti-corrosion function, so it is widely used in power tower, railway, highway protection, light industry and so on.
Ladder type cable tray is improved and designed according to practical application. It is applicable to the laying of general cables with large diameter and high and low voltage power cables.
Ladder type cable tray has the advantages of light weight, convenient installation, good heat dissipation and ventilation. Similarly, it has the disadvantages of non dustproof and low anti-interference ability.
