Kodi ma surfactants amagwira ntchito ziti poyeretsa ma pickling?

1 Monga Acid Mist Inhibitors

Pa pickling, hydrochloric acid, sulfuric acid, kapena nitric acid mosalephera amachitira ndi gawo lapansi lachitsulo pamene akulimbana ndi dzimbiri ndi sikelo, kutulutsa kutentha ndi kutulutsa asidi wochuluka wa nkhungu. Kuonjezera ma surfactants panjira ya pickling, chifukwa cha zochita za magulu awo a hydrophobic, kumapanga filimu yokhazikika, yosasungunuka yozungulira pamwamba pa yankho la pickling. Pogwiritsa ntchito thovu la ma surfactants, kuphulika kwa acidity kumatha kuthetsedwa. Zachidziwikire, ma corrosion inhibitors nthawi zambiri amawonjezedwa ku njira zowotchera, zomwe zimachepetsa kwambiri dzimbiri lachitsulo ndikuchepetsa kusinthika kwa haidrojeni, potero amachepetsa nkhungu ya asidi.

2 Monga Kutolera Kophatikizana ndi Kuchotsa Mafuta

Nthawi zambiri zida zamafakitale zotsuka, ngati zotayira zili ndi zigawo zamafuta, kuyeretsa kwa alkaline kumachitidwa koyamba kuonetsetsa kuti pickling ndi yabwino, kenako kuyeretsa asidi. Ngati kuchuluka kwa degreasing wothandizira, makamaka nonionic surfactants, anawonjezera ku pickling njira, masitepe awiri akhoza pamodzi ndondomeko imodzi. Kuphatikiza apo, njira zambiri zoyeretsera zolimba zimakhala ndi sulfamic acid ndipo zimakhala ndi ma surfactants, thiourea, ndi mchere wa inorganic, womwe umachepetsedwa ndi madzi musanagwiritse ntchito. Kuyeretsa kotereku sikungokhala ndi dzimbiri komanso masikelo ochotsa komanso kuletsa dzimbiri komanso kumachotsa mafuta nthawi imodzi.
