Ukusetshenziswa kweqembu le-surfactant

Ingxoxo yokusetshenziswa kweqembu le-surfactant entsha-hhayi nje into ehlanganisiwe, kodwa ezindaweni zayo eziyinkimbinkimbi kanye nezinhlelo zokusebenza-kumele ifake izici zomnotho ezifana nendawo engase ibe khona emakethe ye-surfactant. Ama-surfactants akha inqwaba yama-ejenti asebenza phezulu, kodwa iqembu lezinhlobo ezingaba ngu-10 kuphela ezakha imakethe ye-surfactant. Ukusetshenziswa okubalulekile kwenhlanganisela kungalindelwa kuphela uma ingeyaleli qembu. Ngakho-ke, ngaphandle kokuphumelela nokuvikeleka kwemvelo, umkhiqizo kufanele utholakale ngesisekelo sezindleko ezifanele, uma uqhathaniswa noma ube nenzuzo enkulu kunaleyo yama-surfactants asevele esungulwe emakethe.

Ngaphambi kuka-1995, i-surfactant ebaluleke kakhulu kuseyinsipho evamile, esetshenziswa izinkulungwane zeminyaka. ilandelwa i-alkylbenzene sulfonate kanye ne-polyoxyethylene alkyl ethers, zombili zimelelwe ngokuqinile kuzo zonke izinhlobo zokuhlanza, okuyindawo eyinhloko yokukhipha izinto ezisetshenziswayo. Nakuba i-alkylbenzene sulfonate ithathwa “njengehhashi lomsebenzi” lezihlanzi, i-alcohol sulfate enamafutha kanye ne-ether sulfate yizinto ezihamba phambili zokukhiqiza imikhiqizo yokunakekelwa komuntu siqu. Kusukela ezifundweni zohlelo lokusebenza kwatholakala ukuthi i-alkyl polyglucosides, phakathi kokunye, ingadlala indima kuyo yomibili le mikhakha. zingahlanganiswa namanye ama-nonionic surfactants ukuze kube nenzuzo ezinhlelweni zokuhlanza izingubo ezisindayo kanye nama-sulfate surfactants ezihlahleni ezilula, kanye nasezicelweni zokunakekela umuntu. Ngakho-ke, ama-surfactants angashintshwa ama-alkyl polyglucosides afaka phakathi i-alkylbenzene sulfonate eqondile kanye nama-surfactants e-sulfate, ngaphezu kokukhethekile okunenani eliphezulu okufana ne-betaine nama-amine oxides.

Isilinganiso samandla okushintsha ama-alkyl polyglucosides kufanele avumele izindleko zokukhiqiza, okuvela ukuthi zisebangeni eliphezulu phakathi kwama-surfactants e-sulfate. Ngakho-ke, i-alkyl polyglucosides izosetshenziswa ngesilinganiso esikhulu hhayi kuphela ngenxa "yamagagasi aluhlaza" nokukhathazeka kwemvelo kodwa futhi ngenxa yezindleko zokukhiqiza futhi njengoba kulindelekile ezindaweni eziningi ze-physicochemical, ukusebenza kwazo okuvelele emikhakheni eminingi yokusetshenziswa.

I-Alkyl polyglucosides izoba nentshisekelo noma kuphi lapho izinga lokushisa lingekho phezulu kakhulu futhi okuphakathi nendawo kungenayo i-asidi kakhulu ngenxa yokuthi ama-acetals esakhiwo sikashukela enza i-hydrolyze ibe utshwala obunamafutha kanye neglucose. ukuzinza kwesikhathi eside kunikezwa ku-40℃ naku-PH≥4. Ku-PH engathathi hlangothi ngaphansi kwezimo zokufafaza, amazinga okushisa afika ku-140℃ awawubhubhisi umkhiqizo.

I-Alkyl polyglucosides izothandeka ukuthi isetshenziswe nomaphi lapho ukusebenza kwayo okuhle kakhulu kwe-surfactant kanye nezakhiwo ezivumelana nemvelo zifiswa, okungukuthi, kwezimonyo nasemikhiqizweni yasendlini. kodwa ukungezwani kwazo okuphansi kakhulu kobuso, amandla aphezulu okuhlakaza, kanye nokukhihliza amagwebu okulawulwa kalula kubenza bathandeke ezinhlelweni eziningi zobuchwepheshe. ikhono lokusebenzisa i-surfactant alincikile nje kuphela ezintweni zayo kodwa nakakhulu ekusebenzeni kwayo uma kuhlanganiswe nezinye izinto ezisebenza emanzini. Ukuba ngama-anionic kancane, noma ama-betaine surfactants. Ukuvumela izenzakalo ze-clouding. zibuye zihambisane nama-cationic surfactants.

Ezimweni eziningii-alkyl polyglucosidesbabonise imiphumela evumayo ye-synergistic ngokuhlangana nabanye abasebenzisa i-surfactants, futhi ukusetshenziswa okungokoqobo kwale mithelela kubonakala kusibalo sezicelo zelungelo lobunikazi ezingaphezu kuka-500 kusukela ngo-1981. umsebenzi omncane kanye nezihlanzi ezisindayo; abahlanza inhloso yonke; izihlanzi ze-alkaline; imikhiqizo yokunakekelwa komuntu siqu njengama-shampoos, ama-gel okugeza, ama-lotions, nama-emulsions; ukuhlakazeka kwezobuchwepheshe okufana nokunamathisela kombala; ukwakheka kwama-foam inhibitors;demulsifiers; izinto zokuvikela izitshalo; okokugcoba; uketshezi oluwuketshezi; namakhemikhali okukhiqiza uwoyela, ukubala ambalwa.
