Explosion-proof electrical equipment: How to repair aging and peeling coating on the enclosure
Thread Content
For explosion-proof electrical equipment, \"the paint or coating applied to the metal enclosure constitutes the non-metallic parts of the enclosure.\" During use, the coating on the enclosure of electrical equipment may age and peel off; therefore, it is necessary to know how to repair and repaint it, as well as what specific requirements exist regarding the paint used
For repairing the coating on explosion-proof electrical enclosures, it is first necessary to select a coating that meets explosion-proof requirements; such coatings should possess oil resistance, corrosion resistance, and good insulating properties. Before repairing, use sandpaper or a steel brush to remove rust and old paint from the damaged area, ensuring that the surface is clean, dust-free, and dry. Then apply a layer of anti-corrosion primer to enhance adhesion and protection. After the primer has dried completely, apply at least two layers of the appropriate explosion-proof topcoat. After each coating application, wait until the previous layer is completely dry before applying the next layer. .
