Ukusetyenziswa kweqela le-surfactant

Ingxoxo ngokusetyenziswa kweqela le-surfactant eselitsha-hayi kakhulu njengekhompawundi, kodwa kwiipropathi zalo ezinobugocigoci kunye nezicelo-kufuneka ibandakanye imiba yoqoqosho enjengendawo enokwenzeka kuyo kwimarike ye-surfactant. Ii-surfactants zenza inkitha yee-arhente ezisebenza kumphezulu, kodwa iqela elimalunga ne-10 kuphela iindidi ezahlukeneyo zenza imarike ye-surfactant. Ukusetyenziswa okubalulekileyo kwekhompawundi kunokulindelwa kuphela xa ikweli qela. Ke ngoko, ngaphandle kokusebenza ngokufanelekileyo nokukhuseleka kokusingqongileyo, imveliso kufuneka ifumaneke ngexabiso elifanelekileyo, xa ithelekiseka okanye ibe luncedo ngakumbi kunezo ze-surfactants esele zizinzile kwimarike.

Ngaphambi kowe-1995, eyona nto ibalulekileyo kwisepha isepha eqhelekileyo, ebisetyenziswa kangangamawaka eminyaka. ilandelwa yi-alkylbenzene sulfonate kunye ne-polyoxyethylene alkyl ethers, zombini zimelwe ngamandla kuzo zonke iintlobo zokucoca, eziyeyona ndawo iphambili yokuphuma kwi-surfactants. Ngelixa i-alkylbenzene sulfonate ithathwa ngokuba “njengehashe lomsebenzi” kwizicoci zokuhlamba impahla, i-alcohol enamafutha sulfate kunye ne-ether sulfate zezona zinto ziphambili zokusebenzisa imveliso yokhathalelo lomntu. Ukususela kwizifundo zokusetyenziswa kwafunyaniswa ukuba i-alkyl polyglucosides, phakathi kwabanye, inokuhlawula indima kuzo zombini iinkalo. zinokudityaniswa nezinye ii-nonionic surfactants ukuze zibe luncedo kwizinto zokucoca iimpahla kunye ne-sulfate surfactants kwi-light duty detergents, kunye nakwizicelo zokhathalelo lomntu. Ke, ii-surfactants ezinokutshintshwa yi-alkyl polyglucosides zibandakanya umgca we-alkylbenzene sulfonate kunye nee-surfactants ze-sulfate, ukongeza kwizinto ezinexabiso eliphezulu ezifana ne-betaines kunye ne-amine oxides.

Uqikelelo lokutshintsha okunokubakho kwealkyl polyglucosides kufuneka kuvumeleke iindleko zemveliso, ezithi zibonakale zikuluhlu oluphezulu phakathi kweesurfactants zesulfate. Ngaloo ndlela, i-alkyl polyglucosides iya kusetyenziswa kwinqanaba elikhulu kungekhona nje ngenxa "yamaza aluhlaza" kunye nokukhathazeka kokusingqongileyo kodwa nangenxa yeendleko zokuvelisa kunye njengoko kulindelwe kwiipropati ezininzi ze-physicochemical, ukusebenza kwazo okugqwesileyo kwiinkalo ezininzi zokusetyenziswa.

I-Alkyl polyglucosides iya kuba nomdla naphi na apho amaqondo obushushu angekho phezulu kakhulu kwaye i-medium ayinayo i-asidi kakhulu ngenxa yokuba ii-acetals zesakhiwo seswekile eyenza i-hydrolyze kutywala obunamafutha kunye ne-glucose. ukuzinza kwexesha elide kunikwa kwi-40℃ kunye ne-PH≥4. Kwi-PH engathathi hlangothi phantsi kweemeko zokutshiza-zomisa, amaqondo obushushu ukuya kwi-140℃ awayitshabalalisi imveliso.

I-Alkyl polyglucosides iya kuba nomtsalane ukuba ingasetyenziswa naphi na apho intsebenzo yazo igqwesileyo ye-surfactant kunye neempawu ezithandekayo ze-ecotoxicological zifunwa, oko kukuthi, kwizinto zokuthambisa kunye neemveliso zasekhaya. kodwa ingxabano yabo ephantsi kakhulu phakathi kobuso, amandla aphezulu okusasaza, kunye nokulawulwa ngokulula kwamagwebu kubenza babe nomtsalane kwizicelo ezininzi zobugcisa. ukukwazi ukufaka i-surfactant akuxhomekanga kwiipropati zayo kuphela kodwa nangakumbi ekusebenzeni kwayo xa kudityaniswe nezinye ii-surfactants. Ukuba yi-anionic encinci, okanye i-betaine surfactants. Ukuvumela i-clouding phenomena. zikwahambelana ne-cationic surfactants.

Kwiimeko ezininziialkyl polyglucosidesbabonise iziphumo ezincomekayo ze-synergistic ngokudityaniswa nezinye ii-surfactants, kwaye ukusetyenziswa okubonakalayo kwezi ziphumo kubonakaliswa kumfanekiso ongaphezulu kwama-500 ezicelo zelungelo elilodwa lomenzi wechiza ukusukela ngo-1981. umsebenzi olula kunye nezihlambululi ezinzima; abacoci benjongo zonke; abacoci bealkaline; iimveliso zokhathalelo lomntu ezifana neeshampu, iijeli zeshawa, iiloshini, kunye neemulsions; i-dispersions yobugcisa njenge-paste yombala; imixube yee-foam inhibitors;demulsifiers; izinto zokukhusela izityalo;izithambisi;ulwelo olusebenza ngolwelo olusebenza ngoxinzelelo lwendalo olusebenza ngoxinzelelo lwendalo. kunye neekhemikhali zokuvelisa ioli, ukukhankanya ezimbalwa.
