ZS-1052 Penetrating graphite antioxidant
one 、 coating summary:
ZS-1052 graphite antioxidant adopts resin main chain fusing technology, and uses cross-linked hydroxy silicone fluoride resin to fuse the resin main chain evenly under high temperature and pressure, and decompose it into nanometer Grade A monomer resin, the modified resin can form a film independently, with a large number of functional groups, strong permeability in graphite, and well wrapped to effectively prevent oxides from contacting graphite and prevent graphite oxidation loss.
2、 Coating characteristics:
① ZS-1052 graphite antioxidant has a large number of nano monomer resins, which can penetrate and seal the tiny graphite voids, wrap the single-layer graphite, physically adhere to the graphite and chemically bridge it, form an integrated structure with the matrix, have good adhesion, and temperature resistance can reach 1800 ℃.
② ZS-1052 graphite antioxidant prevents the penetration of oxidation substances, has extremely low oxygen threshold, and is resistant to the corrosion and penetration of molten slag and high-temperature sundries, with an oxygen diffusion rate of more than 96%. It is resistant to graphite oxidation and corrosion, and protects graphite from oxidation and prolonging its service life in high-temperature oxidation atmosphere and molten liquid.
three Coating construction:
ZS-1052 graphite anti oxidant single component coating has low viscosity. Graphite materials can be applied with negative pressure dip coating and normal pressure brush coating. Generally, negative pressure dip coating and normal pressure brush coating should be applied more than twice. Under standard construction environment, the construction should be conducted once every 2 hours. If the temperature is too low or the air humidity is too high, the construction interval should be correspondingly long.
four Usage
ZS-1052 graphite antioxidant tightly wraps the graphite element, and there is a layer of bright film on the surface of the coated graphite piece. The graphite piece does not shed black, and it is waterproof and anti-corrosion. After being placed for 24 hours, the coating should be gradually heated to further solidify before use, and the graphite piece should be heated to 200-300 ℃ for temperature rise and solidification.
According to the size of the graphite piece, at 200-300 ℃, it should be heated continuously for at least 5 minutes. During the first heating process, there will be smoke, and after reheating, there will be no smoke. The heated graphite parts can be used in high-temperature oxidation atmosphere.
