Which paint types are suitable for use on steel space frame structure in chemical plants?
Chemical plant steel structure paint requires corrosion resistance such as water resistance, moisture resistance, heat resistance, hot steam, and alkali resistance. Chemical plant steel space frame structure paint types include: alkyd, epoxy, polyurethane, acrylic, acrylic polyurethane, silicone resin and fluorocarbon resin. Chemical plant steel structure paint painting requirements: 1. Sandblasting and rust removal of steel structure parts that have been cut to Sa2.5 level. 2. The prefabricated parts after sandblasting shall be painted with epoxy iron red primer within 4 hours, with a thickness of ≥40µm. 3. The pre-welded parts of the prefabricated parts (both sides of the weld bead during welding) are pre-coated with weldable inorganic zinc-rich paint with a thickness of ≥25µm. 4. After the primer surface of the steel structure prefabricated parts is dry, apply the epoxy mica middle layer paint with a thickness of ≥60µm. The following is a matching scheme for...
