Plastic spraying does not need thinners, construction to the environment pollution-free, non-toxic to the human body; Excellent coating appearance quality, strong adhesion, and mechanical strength; Short curing time for spraying construction; Coating corrosion resistance wear resistance is much higher;No primer required;Simple construction, low technical requirements for workers;The cost is lower than the painting process;Some construction occasions have clearly proposed the use of electrostatic spraying process;Electrostatic powder spraying process will not appear in the painting process of common flowing phenomenon.
This is the workshop where workers are spraying plastic.
Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective metal anti-corrosion method, mainly used in various industries of metal structure facilities.It is to dip the de-rusted steel parts into the molten zinc solution at about 500℃, so that the surface of the steel members adhere to the zinc layer, so as to play the purpose of antisepsis.
The anti-corrosion life of hot-dip galvanization is long, but the anti-corrosion life varies in different environments: 13 years in heavy industrial areas, 50 years in the ocean, 104 years in the suburbs, and 30 years in cities.
Principle of hot-dip galvanizing: iron is cleaned, then treated with solvent, dried and dipped into zinc solution, iron and molten zinc react to form an alloyed zinc layer, the process is: degreasing — washing — pickling — help plating — drying — hot dip galvanizing — separation — cooling — passivation.
Advantages of hot dip galvanizing:
1. Low treatment cost: the cost of anti-rust hot dip galvanizing is lower than that of other coatings;
2, durable: in the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained for more than 50 years without the need to repair;In urban or offshore areas, the standard hot dip galvanized rust protection layer can be maintained for 20 years without having to be repaired;
3, good reliability: galvanized layer and steel is metallurgical combination, become a part of the steel surface, so the coating durability is more reliable;
4. Strong toughness of the coating: the galvanized coating forms a special metallurgical structure that can withstand mechanical damage during transportation and use;
5, comprehensive protection: every part of the plating can be plated with zinc, even in the sag, sharp corners and hidden places can be fully protected;
6, save time and effort: the process of galvanizing is faster than other coating construction method, and can avoid the installation of the time required for painting on the site.
The surface treatment of warehouse shelf can not be ignored, it is also an important aspect to investigate the quality of warehouse shelf.The surface treatment is not up to standard, the warehouse shelf is easy to rust corrosion, affecting the service life of the warehouse shelf.
