Apickling Hanyar da aiwatar da daidai sumul karfe bututu

1. Madaidaicin m karfe bututu pickling tsari

Daidaitaccen sumul karfe bututu pickling Hanyar yafi hada da impregnated acid wanke hanya, fesa acid wanka Hanyar da acid manna tsatsa kau method.Generally, mu yi amfani da impregnated acid wanka Hanyar, da kuma SPRAY Hanyar za a iya amfani da taro production.Steel sassa ne kullum pickling. a cikin 10% ~ 20% (girman) maganin sulfuric acid a zafin jiki na 40 C. Lokacin da maganin abun ciki na baƙin ƙarfe ya wuce 80g / L kuma ferrous sulfate ya wuce 215g / L, ya kamata a maye gurbin ruwan acid. A dakin da zafin jiki, tare da 20 % ~ 80% (girma) na hydrochloric acid bayani ga karfe pickling, ba sauki faruwa lalata da hydrogen gaggautsa sabon abu.Due ga babban lalata sakamako na acid a kan karfe, lalata inhibitor an kara.Bayan tsaftacewa, da karfe surface zama azurfa fari. , da wuce gona da iri don inganta juriyar lalata na bakin karfe.

Domin kawar da adsorption na saman da kuma rage chromatographic peak ja wutsiya, mai ɗaukar kaya ya kamata a bi da shi tare da wanke acid ko wanke alkali kafin amfani. , tacewa, wanke zuwa tsaka tsaki, da bushewa.Acid wankewa zai iya cire baƙin ƙarfe, aluminum, calcium, magnesium da sauran ƙazanta a kan tebur, amma ba zai iya cire rukunin barasa na silicone ba. Mai ɗaukar hoto ya dace da nazarin samfurori na acidic.
