Zeziphi iindima ezithile ezidlalwa zii-surfactants ekucoceni ii-pickling?

1 Njenge-Acid Mist Inhibitors

Ngexesha lokucola, i-hydrochloric acid, i-sulfuric acid, okanye i-nitric acid ngokungenakuphepheka isabela kwi-metal substrate ngelixa isabela ngokugqwala kunye nobukhulu, ivelisa ubushushu kwaye ivelise inani elikhulu le-acid inkungu. Ukongeza ii-surfactants kwisisombululo se-pickling, ngenxa yesenzo samaqela azo e-hydrophobic, kwenza i-linear film coating ejolise, enganyibilikiyo kumphezulu wesisombululo se-pickling. Ukusebenzisa isenzo se-foam se-surfactants, i-acid mist volatilization inokuthintelwa. Kakade ke, ii-corrosion inhibitors zihlala zongezwa kwizisombululo ze-pickling, ezinciphisa kakhulu izinga lokugqwala kwesinyithi kwaye zinciphise ukuvela kwe-hydrogen, ngaloo ndlela zinciphisa i-acid inkungu.

2 Njengokucoca okuDibeneyo kokuCoca nokuCoca amafutha

Ngokubanzi ekucoceni iikhemikhali zezixhobo zoshishino, ukuba ukungcola kuqulethe izinto zeoyile, ukucoca i-alkaline kuqala kwenziwa ukuqinisekisa umgangatho wokucoca, kulandele ukucoca i-asidi. Ukuba isixa esithile se-arhente yokususa amafutha, ngakumbi ii-surfactants ezingezizo ii-ionic, zongezwa kwisisombululo sokucoca, la manyathelo mabini anokudityaniswa abe yinkqubo enye. Ukongeza, uninzi lwezisombululo zokucoca eziqinileyo luquka ikakhulu i-sulfamic acid kwaye luqulathe isixa esithile se-surfactants, i-thiourea, kunye neetyuwa ezingaphiliyo, ezixutywe ngamanzi ngaphambi kokusetyenziswa. Olu hlobo lwe-arhente yokucoca alunazo nje kuphela iimpawu zokususa umhlwa kunye nezikali kunye nokuthintela ukugqwala kodwa lukwasusa ioyile ngaxeshanye.
