The anti-rust coating for steel structure adopts advanced process formula, scientific design scheme, unique formula and process integrating penetration, transformation and stability, scientifically takes the penetration transformation mechanism as the leading factor, and finally overcomes all kinds of forbidden zones of water-based anti-rust primer, using water as the dispersion medium, using multiple anti-rust mechanisms such as physics and chemistry, and according to chemical principles such as chemical transformation, complexation and reflection. All technical indicators meet and exceed national and industry requirements.
Rust-proof coatings for steel structures have initiated a new era of waterborne rust-proof primers. It is a good substitute for traditional antirust primer. Widely used in all kinds of cars, ships, power grids, machinery manufacturing, containers, railways, bridges, boilers, steel structures, petrochemical equipment and other anti-corrosion protection, solvent-based coatings are incomparable, in line with the development direction of environmental protection at home and abroad, and have been welcomed by various industries since they were put on the market.
2. What are the characteristics of steel structure antirust paint?
1. The antirust paint for steel structure adopts a new generation of ion-stabilized self-emulsifying "core-shell" water-based resin, related fillers and additives, as well as a unique formula and process integrating polymerization, crosslinking, reactivity and emulsification, and adopts a scientific design scheme with self-emulsification as the main part and crosslinking and reactivity as the auxiliary part. After careful selection and scientific formulation, the ultra-fine inorganic non-toxic pigments make a new generation of steel structure antirust paint add a new generation of excellent products to the anti-corrosion painting cause of the motherland.
2. The invention is non-toxic, tasteless, pollution-free, non-combustible and non-explosive, thus ensuring environmental protection and fire safety and ensuring the health of workers. High hardness, scratch resistance, strong adhesion, salt spray resistance, acid and alkali resistance, water resistance, oil resistance, ultraviolet resistance, aging resistance, low temperature resistance, damp heat resistance, and excellent film flexibility. The operation is simple, the product utilization rate is 100%, the work efficiency can be greatly improved, and the unit coating cost is extremely low.
3. What are the precautions for the use of antirust paint for steel structures?
Steel structure antirust paint should be painted in sunny days. The ambient temperature is 5-40℃ and the relative humidity is below 80%. When the ambient humidity is below 3℃ and above 80%, it is not suitable for painting. After painting, the paint film should be rain-proof or washed with water within 4 hours. In order to accelerate the drying of paint film, drying can be carried out, the baking temperature is not lower than 40℃ and the drying time is not less than 20 minutes. It should be stored in a cool and ventilated warehouse, and the storage temperature should not be lower than 0℃, and it should be stored in a greenhouse in winter in northern areas to avoid freezing.
The use of antirust paint for steel structure can make the steel surface smoother as new, and it is not easy to be eroded by more natural conditions, so the steel structure can be as new all the year round and will not rust due to excessive exposure to air. Anti-rust paint for steel structure is widely used, so it is necessary to use it in major steel structure projects at present.
