Description

Anti-corrosion mechanism

The double coating is a combination of hot-dip galvanized and epoxy coatings. The product is first hot-dip galvanized and then coated with epoxy powder on the surface. The hollow rock bolt undergoes two anti-corrosion processes, which have better corrosion resistance and longer service life. It can not only resist ordinary chemical corrosion but also work in acidic environments and electrochemical corrosion of stray currents.

Product standards

The double coating combines all the performance parameters of hot-dip galvanized and epoxy coatings. Hot-dip galvanizing meets the requirements of the table below. Epoxy products are mainly based on EN 13438 "Paints and varnishes - Powder organic coatings for hot-dip galvanized or galvanized steel products for construction", with a minimum coating thickness of ≥60um. The bending properties of epoxy coatings comply with ISO 1519 "Paints and varnishes - bending tests (cylindrical mandrels)". Impact performance conforms to ASTM D2794 "Standard Test Method for Organic Coatings Against the Effects of Rapid Deformation (Impact)". Adhesion complies with ISO 2409 "Paints and varnishes - Cross-cut test".

Features and benefits

Excellent corrosion protection: Zinc is an active metal that protects steel through a battery effect after the coated surface is damaged.
Long service life: The depletion of zinc layers in the atmosphere is very slow, so its service life far exceeds that of any other coating.
Full protection: The product is immersed in the hot-dip galvanized tank for full protection and better corrosion protection.
Lower price: In most cases, hot-dip galvanizing costs less. Zinc coatings are more durable than other coatings and will not require maintenance in the future.
High processing efficiency: The hot-dip galvanizing bath is simple and the efficiency is higher than other coatings.
Does not affect the performance of the steel: hot-dip galvanizing is carried out in an environment above 400 ° C, which will not affect the performance and toughness of the steel.
The selected coating material is thermoset, has excellent chemical corrosion resistance, and does not react with acid, alkali, etc., so that the formed coating is absolutely inert, completely preventing the duplex coating hollow rock bolt from contacting the external environment and preventing corrosion.
After curing, the coating material will not melt even if it is reheated. It has high chemical stability. The resulting coating has high adhesion to the metal, low drying shrinkage, and high ductility. In the case that the coating is not damaged during operation, it can effectively block corrosive substances.

Service life

The service life of the duplex coating hollow rock bolt is usually much longer than that of a single anti-corrosion treatment, which is a synergistic effect. In most environments, the service life of a duplex coating hollow rock bolt can reach 100 years without maintenance; The first maintenance life of the duplex coating hollow rock bolt in a severely corrosive environment is nearly double that of the hot-dip galvanized anchor rod.
