The advantage of BD428 high temperature flakes corrosion resistance coatings:
In the flue gas desulfurization device of the power plants,steel plants,non-ferrous metal factory, chemical plants and waste incineration etc.department,they both have high temperature and corrosion condition,so there is often equipment corrosion perforation etc. phenomenon.
At present,we commonly use the vinyl resin flake plaster-made corrosion resistant protective coating on the market.This plaster uses the vinyl resin as the basic material,supplemented by scales, pigment, special additives and initiator,accelerant etc.
But in the process of using,often appear the following questions:
1.With a large curing shrinkage,in the process of the environment temperature changing,because of its high shrinkage stress, coupled with its poor bonding strength,causing the coating cracks, even fall off.
2.The vinyl resin generally contains about 35% of styrene monomer,and styrene is the flammable, suspected carcinogen and stimulative.Will cause a serious threat to the health of construction personnel.Styrene has serious harm to the environment, will cause pollution to the water,soil and air.
3.The vinyl resin generally contains about 35% of styrene monomer,in the process of using,partical styrene volatilization,causes corrosion resistant coating has a large number of micropores,the diameter of small molecule in the medium is smaller than the coating porosity,as a result, even if the vinyl resin coating is the medium which can be corrosion resistance better,but it's not able to withstand the medium diffusing and permeating to the matrix,influence the coating wear & corrosion resistance.
With too many years endeavour of Xiangyang City Hundred Shield Coating Material Co.,Ltd,it develops a kind of BD428 high temperature flakes corrosion resistance coatings,it can solve the above problems effectively.BD428 flakes corrosion resistance coating is compounded by high temperature resistant resin and our company composite high temperature resistant epoxy curing agent,adding high performance corrosion resistant filling material,glass flake and various additives,carries on the copolymerization reaction,form interpenetrating network structure,produce synergistic effect, effectively improve the corrosion resistance of polymer,can be preparation of the high temperature resistant corrosion resistant coating on the surface of machine part of suffering from corrosion under 200‘ζ.
BD428 high temperature scales corrosion resistant coating is made of modified epoxy resin compound,has high bonding strength,curing without shrinkage etc advantage.
BD428 high temperature flakes corrosion resistance coating uses high temperature resistant epoxy curing agent which is R&D and produced by our company,has high temperature resistant,corrosion resistant and aging resistant ect advantage.
BD428 high temperature scales corrosion resistant coating does not contain any organic solvent, curing material has no the micro pores,it can effectively avoid medium immersing through solvent evaporation pores and causing the under-film corrosion.
BD428 high temperature flakes corrosion resistance coating,room temperature curing,construction is convenient,environmental protection without contamination.
