As a kind of special anticorrosive filler, the glass flake is used to prevent the corrosion of the coating. As a result, glass flake coatings have excellent corrosion resistance and become a new type of corrosion resistant material. Glass flake
Glass flake coating can be widely used in petroleum, petrochemical equipment, pipelines, storage tanks, marine facilities, offshore drilling platforms, chemical gas storage and gas pipelines; flue gas desulfurization device for metallurgical power plant, also can be used as impermeable layer of glass steel equipment.
Glass flake glass by high temperature of 1700 DEG C melting and blown by a unique process of thin pieces of glass has been applied abroad for decades.
Under the condition of high temperature molten state, the glass flake has the characteristics of high strength and low specific gravity.
Glass is an inorganic material, the composition of which determines that it has good chemical resistance and anti-aging properties. Glass flake coating is thin, the correct construction, making it in the coating and the substrate can equal stacking arrangement, like pieces of the scale, such as layers of armor, forming a dense impermeable layer (it was known as the labyrinth structure), according to the survey by tens of hundreds of layers, the corrosive medium diffusion way to protect the substrate becomes the twists and turns, greatly extend the way and time of permeability, improves the anti penetration properties of the coating and corrosion life.
In the coating, a large number of glass scales form a number of small areas, so that the micro cracks in the coating, micro bubbles are divided, greatly reducing the rate of penetration of the media, so that the permeability of the media significantly reduced. Compared with other materials, glass flake coating can improve the permeability of several times to ten times.
The existence of the glass flake not only reduces the difference of the thermal expansion coefficient between the coating and the substrate, but also reduces the hardening shrinkage of the coating. Glass flake coating hardening shrinkage rate, only a fraction of other materials to the number 1/10, which not only helps suppress cracking and spalling of the coating, and the coating can improve the adhesion and impact resistance.
