Zwitterionic detergents zoo li CHAPS lossis SB12 sib txuas cov khoom ntawm ionic thiab nonionic detergents. Lawv nqa ib pab pawg zoo thiab tsis zoo, tab sis zoo li nonionic surfactants, tsis muaj tus nqi them (rau CHAPS thiab sulfobetaines hauv pH ntau ntawm 2 -12).
Dab tsi yog cov tshuaj detergents uas tsis yog-ionic muab piv txwv?
Non-ionic detergents
Cov piv txwv ntawm yav dhau los suav nrog Tween, Triton, thiab Brij series Cov ntaub ntawv no tseem hu ua ethoxylates lossis PEGylates thiab lawv cov metabolites, nonylphenol. Glycosides muaj suab thaj raws li lawv lub taub hau hydrophilic uncharged. Piv txwv suav nrog octyl thioglucoside thiab m altosides.
Dab tsi yog cov tshuaj ntxuav ionic muab piv txwv?
Ionic detergents muaj cov pab pawg thawj coj uas yog qhov zoo lossis tsis zoo. Piv txwv li, anionic detergent sodium dodecyl sulfate (SDS)nqa ib pawg sulfate tsis zoo rau ntawm cov kab C12 hydrocarbon saw. SDS raug suav hais tias yog ib qho muaj zog heev thiab lom zem heev surfactant.
Qhov twg yog cov tshuaj ntxuav tes tsis muaj ionic?
Cov tshuaj ntxuav tes uas tsis yog-ionic yog ua raws li polyoxyethylene lossis glycoside. Pentaerythrityl stearate yog cov tshuaj ntxuav tes uas tsis yog ionic. Sodium lauryl sulphate yog anionic detergent. Cetyl trimethyl ammonium chloride yog cationic detergent. SDS Sodium n-dodecyl benzene sulphonate yog ib qho tshuaj ntxuav tes anionic.
Nononic detergent yog dab tsi?
: ib yam ntawm cov khoom siv hluavtaws (raws li cov saw hlau ntev ether derivatives lossis esters ntawm cawv lossis phenols) uas tsis yog anionic lossis cationic tab sis tsim hluav taws xob nruab nrab colloidal hauv solution.
