Kodi ma surfactants amagwira ntchito yanji makamaka poyeretsa pickling?

1 Monga Zoletsa za Acid Mist

Pa nthawi yopangira pickling, hydrochloric acid, sulfuric acid, kapena nitric acid mosakayikira zimakumana ndi chitsulo pamene zimachita dzimbiri ndi kukula, zomwe zimapangitsa kutentha ndikupanga asidi wambiri. Kuwonjezera ma surfactants ku pickling solution, chifukwa cha momwe magulu awo amagwirira ntchito, kumapanga utoto wozungulira, wosasungunuka pamwamba pa pickling solution. Pogwiritsa ntchito thovu la ma surfactants, acid mist volatilization ikhoza kuchepetsedwa. Zachidziwikire, zoletsa dzimbiri nthawi zambiri zimawonjezeredwa ku pickling solutions, zomwe zimachepetsa kwambiri dzimbiri la zitsulo ndikuchepetsa kusintha kwa haidrojeni, motero zimachepetsa asidi mist.

2 Monga njira yoyeretsera pamodzi ndi kuchotsa mafuta

Kawirikawiri pakuyeretsa zida zamafakitale, ngati kuipitsidwa kuli ndi zigawo zamafuta, kuyeretsa kwa alkaline kumachitika kaye kuti zitsimikizire kuti kuipitsidwa kuli bwino, kutsatiridwa ndi kuyeretsa kwa asidi. Ngati kuchuluka kwa mankhwala ochotsera mafuta, makamaka ma surfactants osakhala a ionic, kwawonjezedwa mu njira yophikira, magawo awiriwa akhoza kuphatikizidwa kukhala njira imodzi. Kuphatikiza apo, njira zambiri zotsukira zolimba zimakhala ndi sulfamic acid ndipo zimakhala ndi kuchuluka kwa ma surfactants, thiourea, ndi mchere wosapangidwa, womwe umasungunuka ndi madzi musanagwiritse ntchito. Mtundu uwu wa mankhwala otsukira sumangokhala ndi mphamvu zabwino zochotsera dzimbiri ndi mamba komanso zoletsa dzimbiri komanso nthawi imodzi zimachotsa mafuta.
