Abstract
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.
Description
Technical field
The invention belongs to the manufacture field of color steel, be specifically related to a kind of strip cleaning technique of color steel.
Background technology
Color steel is in the manufacturing, and the cleaning of band steel is as important process flow process, and band steel, before entering is coated with stove drying, adopts " dipping " technique usually, chemical pretreatment solution is coated onto the surface of band steel; , there is the shortcomings such as floor space is large, heavy contamination in traditional cleaning way.
Summary of the invention
The object of the present invention is to provide a kind of strip cleaning technique of color steel, have that technique is superior and equipment is simple, floor space is little and the advantage of environmental protection.
Technical scheme of the present invention is: the strip cleaning technique of color steel, comprise: (1) band steel enters cleaning section, band steel soaks through chemical liquid, scrubs in cleaning section, after matting process, eliminate surperficial oil contamination, scrub and three grades of hot water rinsings through water again, wash away the scavenging solution that belt steel surface is residual; (2) then, band steel removes the moisture on surface through wind cleaning, for ensuing Chemical Pretreatment provide clean, the substrate surface of dry and passive state; (3) clean dry band steel is through air-dry laggard people's chemistry roller coating machine, and then, band steel carries out Chemical Pretreatment on change painting machine, to strengthen sticking power between coating and substrate and resistance to corrosion
In step (2), band steel is through purging the moisture on removing surface to the directed cold wind of plate face high pressure.
In step (3), chemical pretreatment solution is directly coated onto the upper and lower surface of band steel by application roll.
Beneficial effect: the present invention has that technique is superior and equipment is simple, floor space is little and the advantage such as pollution-free.
Embodiment
Below in conjunction with specific embodiment, the present invention will be further described.
The strip cleaning technique of color steel, comprise: (1) band steel enters cleaning section, band steel soaks through chemical liquid, scrubs in cleaning section, after matting process, eliminate surperficial oil contamination, scrub and three grades of hot water rinsings through water again, wash away the scavenging solution that belt steel surface is residual; (2) then, band steel removes the moisture on surface through wind cleaning, for ensuing Chemical Pretreatment provide clean, the substrate surface of dry and passive state; (3) clean dry band steel is through air-dry laggard people's chemistry roller coating machine, and then, band steel carries out Chemical Pretreatment on change painting machine, to strengthen sticking power between coating and substrate and resistance to corrosion
In step (2), band steel is through purging the moisture on removing surface to the directed cold wind of plate face high pressure.
In step (3), chemical pretreatment solution is directly coated onto the upper and lower surface of band steel by application roll.
Beneficial effect: the present invention has that technique is superior and equipment is simple, floor space is little and the advantage such as pollution-free.
