Long-term corrosion protection of steel structure in chemical plant

The atmospheric environment of chemical plants is very complicated: for example, acid, alkali, oil, water and steam run, run, drip and leak in chemical production; The content of SO2 and other pollutants in the atmosphere is high; When the relative humidity of the atmosphere is more than 70%, it will accelerate the corrosion of steel structures such as equipment, devices, frame supports and pipelines in chemical plants. In order to prevent the steel structures from being corroded, it is necessary to carry out corresponding anti-corrosion coating treatment. Dilin 441 waxy heavy-duty anti-corrosion coating has good anti-corrosion properties such as acid resistance, alkali resistance, high salt resistance and most organic solvents. The base material contains a large number of OH active groups, which react rapidly with the active components in the filler and the active surfaces of steel or other materials to generate inorganic polymers with three-dimensional structure, and connect the coating with the matrix into a whole to form a heat-resistant, acid-resistant and corrosion-resistant coating with electrochemical protection and physical shielding effects, which is especially suitable for the construction of chemical workshops, biological raw material workshops, the outer walls of chemical storage tanks, steel structures and guardrails in chemical workshops, and the coating does not crack, peel or fall off for a long time. In order to make the coating firmly adhere to the surface of the steel structure, the surface of the workpiece must be cleaned before painting, otherwise, it will not only affect the bonding force and corrosion resistance of the coating and the base metal, but also make the base metal continue to corrode even under the protection of the coating, so that the coating will peel off and affect the mechanical properties and service life of the steel structure. Acid and alkali resistant anticorrosive paint can protect the substrate in harsh environment, and has the functions of acid resistance, alkali resistance, corrosion resistance, oxidation resistance, sealing and wear resistance protection. The coating has high stability, can react with other active molecules in high temperature environment, and has long service life. The coating has the properties of wear resistance, corrosion resistance, and cracking and peeling resistance. Dilin 441 wax coating is used for long-term anticorrosion in hydrochloric acid, acid workshop, high salt workshop, organic solvent workshop, chemical plant and equipment.
