The invention relates o a working and cleaning circulating system of a coating liquid. The working and cleaning circulating system comprises a working pot (1), a washing water pot (4), a first circulating pump (19), an upper coating roller (38), a lower coating roller (39), a waste liquid collection box (32), a first pipeline (12), a second pipeline (15), a third pipeline (21), a fourth pipeline (28), a fifth pipeline (30), a sixth pipeline (33), a seventh pipeline (34) and an eighth pipeline (36), wherein the washing water pot (4) is connected with the working pot (1) through the first pipeline (12); and the first pipeline (12) is provided with a first control valve (13) and a second control valve (14). The working and cleaning circulating system of the coating liquid disclosed by the invention has two working modes including a coating mode and a washing mode; and the conversion of the two working modes is very convenient and the washing efficiency is high.
Description
technical field [0001] The invention relates to the field of coating, and more specifically relates to a working and cleaning circulation system for coating liquid. Background technique [0002] In order to improve the corrosion resistance of the zinc layer on the surface of the strip steel and increase some special properties of the galvanized sheet, such as fingerprint resistance, lubricity, machinability and ease of painting, etc., it is necessary to passivate the surface of the galvanized sheet and / or anti-fingerprint treatment. Passivation treatment is to use chromate solution to treat the zinc layer, so that a layer of chromate conversion film is formed on the surface of the galvanized layer, that is, the passivation film of the galvanized layer to improve its corrosion resistance, and anti-fingerprint treatment is Coating conductive SiO on the surface of the zinc layer 2 The organic composite resin film (thickness δ=1~3μm) makes the galvanized sheet have fingerprint...
