Dispersing agents, tseem hu ua dispersants, yog cov tshuaj uas muaj surfactants thiab/lossis cov kuab tshuaj sib xyaws uas ua rau cov roj av tawg ua cov tee me me.
Yuav ua li cas hauv qab no yog piv txwv ntawm kev sib cais tus neeg sawv cev?
Dispersing agents belongs to mainly formaldehyde condensates ntawm naphthalene sulphonic acid, cresol, 1-naphthol 6-sulphonic acids, fatty alcoholethylene oxide condensate, alkyl aryl sulphonsulates los yog lignin. - cov condensate ntawm naphthalene sulphonic acid yog qhov nrov tshaj plaws.
Dab tsi yog tus neeg sawv cev sib faib hauv chemistry?
A dispersant lossis dispersing agent yog ib yam khoom, feem ntau yog surfactant, uas yog ntxiv rau kev ncua ntawm cov khoom lossis cov kua hauv cov kua (xws li colloid lossis emulsion) txhawm rau txhim kho kev sib cais ntawm cov khoom thiab tiv thaiv lawv qhov chaw los yog clumping.
Dab tsi yog cov tshuaj dispersants?
Cov hluavtaws surfactants tuaj yeem yog anionic, cationic, nonionic, lossis amphoteric; Txawm li cas los xij, tsuas yog anionic lossis nonionic surfactants yog siv los ua cov roj crude dispersants. Surfactant mixtures feem ntau suav nrog lwm cov tshuaj, xws li cov kuab tshuaj, uas txhim khu lub peev xwm dispersing ntawm surfactant [10].
Vim li cas thiaj siv bio dispersants?
Siv bio dispersants
A bio dispersant tuaj yeem yog siv tau ob qho tib si tshem tawm biofilm ntawm lub kaw lus thiab tiv thaiv kev txhim kho biofilm hauv ib qhohuv system. Raws li nws paub tias cov kab mob Legionella xaiv loj hlob nyob rau hauv cov khaubncaws sab nraud povtseg ntawm biofilm, ua kom lub cua txias ntauwd biofilm tsis muaj qhov tseem ceeb.
