Long term anti corrosion on the selection of YMS water based inorganic zinc rich paint
Waterborne inorganic zinc-rich coating is a kind of long-acting antirust coating, which has three kinds of antirust properties on steel surface, namely cathodic protection, forming passivation film and covering effect, and strong antirust performance.Because water-based inorganic zinc-rich coating with water as diluent, VOC content is zero, so non-toxic and tasteless, storage, transportation and construction process safe and pollution-free, strong anti-ultraviolet ability.
Waterborne inorganic zinc-rich coating for exposure to the ocean atmosphere, high temperature and a variety of environment of a variety of steel members of the long-term anti-corrosion, especially suitable for oil storage tank bottom plate from the inner wall of the anti-corrosion, oil tanker, solvent tank inside and outside the anti-corrosion, used as a strong corrosive environment of the steel structure of the long-term anti-corrosion.
The reason why water-based inorganic zinc rich primer can be long-lasting anti-corrosion is mainly because:
1. Electrochemical protection.According to zinc is more active than iron, YMS water-based inorganic zinc rich primer uses a large amount of high purity superfine zinc powder as anticorrosive pigment, because zinc is used as a sacrificial anode, and steel is protected.
2. Good durability.Through the physical and chemical combination of coating and steel, the adhesion between coating and steel matrix is strong.The zinc salt and zinc complex formed by zinc powder on the surface of the coating can block the gaps, cracks and holes of the coating, prevent the corrosion of oxygen, water and other media, and is not affected by atmospheric conditions and ultraviolet radiation, the coating has a long service life and low maintenance cost.
3. Good self-sealing.When the film of Jianbang water-based inorganic zinc rich primer is injured, zinc is oxidized into basic zinc oxide, zinc hydroxide, zinc carbonate and other composite passivation film, which can prevent corrosion under the film and the film frothing and peeling.
In addition, "Jian Bong Paint" water-based inorganic zinc rich primer has better characteristics than other manufacturers, in the coating matching, can be matched with acrylic polyurethane, epoxy paint, vinyl paint.
Before applying topcoat and coat coat, the applied paint should be diluted with 15-20% thinner (by weight of paint).
