Strip steel cleaning technology of color steel plate

A strip steel cleaning technology of color steel plate comprises the following steps: (1) delivering strip steel to a washing section, in the washing section, soaking strip steel in a chemical solution, scrubbing strip steel, subjecting strip steel to chemical washing to remove the greasy stains on the surface, then washing the strip steel by water, and rinsing the strip steel by hot water in three grades so as to wash off the residual cleaning solution on the surface of strip steel; (2) then blowing off the water on the surface of strip steel to obtain a clean, dry, and passivated substrate surface for the subsequent chemical pretreatment; (3) drying the clean and dry strip steel in air, then transferring the strip steel to a chemical roller coating machine, and then carrying out chemical pretreatment on the strip steel in a chemical coating machine. The provided technology has the advantages of excellence, simple equipment, little occupied area, and no pollution.
