Kubalulekile ukuqaphela ukuthi la ma-surfactants awawona ama-ejenti angena-foam. Kunalokho, ngaphezu kwezinye izakhiwo, ahlinzeka ngendlela yokulawula i-am...Funda kabanzi -
Kungani kufanele ukhethe i-surfactant ene-foam ephansi?
Uma ukhetha ama-surfactant ezinhlobo zakho zokuhlanza noma izinhlelo zokusebenza zokucubungula, i-foam iyisici esibalulekile. Isibonelo, ezisetshenzisweni zokuhlanza indawo eqinile ngesandla—njengemikhiqizo yokunakekela izimoto noma ukugeza izitsha okugezwa ngesandla—amazinga aphezulu e-foam avame ukuba yisici esifiselekayo. Lokhu...Funda kabanzi -
Yiziphi izindlela zokusebenzisa ama-biosurfactants kubunjiniyela bezemvelo?
Ama-surfactant amaningi akhiwe ngamakhemikhali alimaza indawo ezungezile ngenxa yokubola kwawo, ubuthi, kanye nokuthambekela kwawo kokuqongelela ezindaweni zemvelo. Ngokuphambene nalokho, ama-surfactant ezinto eziphilayo—abonakala ngokubola kalula kanye nokungabi nobuthi ezinhlelweni zemvelo—afaneleka kangcono...Funda kabanzi -
Ziyini izinto ezibangela ukusha kwesikhumba?
Ama-biosurfactants angama-metabolites akhishwa ama-microorganisms ngesikhathi sezinqubo zawo ze-metabolic ngaphansi kwezimo ezithile zokutshala. Uma kuqhathaniswa nama-surfactants akhiwe ngamakhemikhali, ama-biosurfactants anezimfanelo eziningi ezihlukile, njengokuhlukahluka kwesakhiwo, ukubola kwe-bio, ukusebenza okubanzi kwe-biological...Funda kabanzi -
Yiziphi izindima ezithile ezidlalwa ama-surfactants ekuhlanzeni okuhlukahlukene?
1. Ukusetshenziswa Ekuhlanzeni Kwe-Chelating Ama-chelating agents, aziwa nangokuthi ama-complexing agents noma ama-ligands, asebenzisa i-complexation (ukuxhumanisa) noma i-chelation yama-chelating agents ahlukahlukene (kufaka phakathi ama-complexing agents) anama-ion okukala ukukhiqiza ama-complexes ancibilikayo (ama-coordinate compounds) okuhlanza i-p...Funda kabanzi -
Iyiphi indima edlalwa ama-surfactants ekuhlanzweni kwe-alkaline
1. Ukuhlanza Imishini Ejwayelekile Ukuhlanza i-alkaline kuyindlela esebenzisa amakhemikhali ane-alkaline enamandla njengezinto zokuhlanza ukukhulula, ukuxuba, nokusabalalisa ukungcola ngaphakathi kwemishini yensimbi. Ivame ukusetshenziswa njengokwelashwa kwangaphambi kokuhlanza i-asidi ukususa uwoyela ohlelweni nasemishinini noma ukuguqula...Funda kabanzi -
Yiziphi izindima ezithile ezidlalwa ama-surfactants ekuhlanzeni i-pickling?
1 Njengezithibi Zokuncibilikisa I-Acid Mist Ngesikhathi sokuncibilikisa, i-hydrochloric acid, i-sulfuric acid, noma i-nitric acid ngokungenakugwenywa isabela ne-substrate yensimbi ngenkathi isabela ngokugqwala kanye nesikali, ikhiqiza ukushisa futhi ikhiqize inani elikhulu le-acid mist. Ukwengeza ama-surfactant esixazululweni sokuncibilikisa, ngenxa yesenzo se...Funda kabanzi -
Yiziphi izindlela zokusebenzisa ama-surfactants ekuhlanzeni amakhemikhali?
Ngesikhathi sezinqubo zokukhiqiza zezimboni, izinhlobo ezahlukene zokungcola, njengokupheka, izinsalela zikawoyela, isikali, inhlabathi, kanye namadiphozithi agqwalisayo, aqoqana emishinini nasemapayipini ezinhlelo zokukhiqiza. Lawa madiphozithi avame ukuholela ekungasebenzi kahle kwemishini kanye namapayipi, ukwehla kokusebenza kahle kokukhiqiza...Funda kabanzi -
Kuziphi izindawo lapho i-flotation ingasetshenziswa khona?
Ukufakwa kwe-ore kuwumsebenzi wokukhiqiza olungiselela izinto zokusetshenziswa zokuncibilikisa insimbi kanye nemboni yamakhemikhali. Ukuflotha kwe-froth sekuyindlela ebaluleke kakhulu yokucubungula amaminerali. Cishe zonke izinsiza zamaminerali zingahlukaniswa kusetshenziswa ukuflotha. Ukuflotha okwamanje kusetshenziswa kabanzi...Funda kabanzi -
Kuyini ukuhlomula kwe-flotation?
I-Flotation, eyaziwa nangokuthi i-froth flotation, iyindlela yokucubungula amaminerali ehlukanisa amaminerali abalulekile kumaminerali e-gangue endaweni yokuhlangana kwegesi-uketshezi-eqinile ngokusebenzisa umehluko ezimpahleni zamaminerali ahlukene. Ibizwa nangokuthi “ukuhlukaniswa kwe-interfacial.”Funda kabanzi -
Isebenza kanjani i-demulsifier yamafutha?
Indlela yokusebenza kwama-demulsifier kawoyela ongahluziwe isekelwe ku-phase inversion-reverse deformation theory. Ngemva kokufaka i-demulsifier, kwenzeka i-phase inversion, ekhiqiza ama-surfactant akhiqiza uhlobo oluphambene nolwe-emulsion oludalwa yi-emulsifier (i-reverse demulsifier). ...Funda kabanzi -
Kufanele siwahlanze kanjani amabala kawoyela ezingxenyeni zensimbi?
