Umehluko Weyunithi Ye-EO Ngezinombolo Ezimbalwa, Kungani Ukusebenza Kokwakheka Kuhluka Kakhulu? — Ukuqonda Ukukhethwa Kwe-Fatty Amine Ether nge-Qixuan TA05

Ngesikhathi semihlangano yokukhetha i-surfactant, inselele evamile ivame ukuvela: ama-ether amabili e-fatty amine polyoxyethylene anomehluko omncane kuphela kumayunithi e-ethylene oxide (EO) kanye namathegi entengo afanayo angaletha imiphumela ehluke kakhulu uma esefakwe ekwakhiweni okusebenzayo. Ukuqina kwe-emulsion, i-viscosity yesistimu kanye nombala womkhiqizo oqediwe kuzoshintsha ngokusobala. Ekukhonzeni amakhasimende kuzo zonke izindawo zokuhlanza, insimu kawoyela, i-agrochemical emulsification, i-asphalt, ukucubungula amaminerali kanye neminye imikhakha, ithimba lobuchwepheshe leShanghai Qixuan Chemical Technology Co., Ltd. livame ukubuzwa umbuzo owodwa oyinhloko: ungayikhetha kanjani inombolo efanele ye-EO?

TA05, okungukuthi i-tallow amine polyoxyethylene (5) ether, inikeza isisombululo esimele kulo mbuzo. Ayilandeli ukusebenza okweqile enkombeni eyodwa, kodwa ithola indawo yayo ethembekile ezinhlobonhlobo zezinhlelo zokusebenza ezahlukahlukene kakhulu.

I-TA05 yenziwa nge-ethoxylation ye-tallow amine yemvelo enamayunithi angu-5 EO, i-CAS No. 61791-26-2. Ingxenye yayo engabangeli manzi iqukethe amaketanga amade e-alkyl e-C16–C18 axubile, kuyilapho ingxenye ebangelisayo inikelwa ngokuhlanganyela ngamayunithi amahlanu e-EO kanye neqembu lama-amine elitholakalayo.

Lesi sakhiwo esiyingqayizivele sisinika ubunikazi obubili bokusebenza. Ngaphansi kwezimo ezingathathi hlangothi noma ze-alkaline, sisebenza njenge-surfactant engeyona i-ionic, senza i-emulsification kanye nokuhlakazeka ngokumanzisa amaketanga e-EO. Ezindaweni ezine-acidic, iqembu le-amine liyavela futhi lithwale amashaja amahle, libonisa izici ze-cationic surfactant ezihambisana kakhulu ne-adsorption kuma-substrates ashajwe kabi okuhlanganisa izindawo zensimbi, amaminerali, imicu kanye nezinhlayiya ze-asphalt. Le ndlela yokusebenza ephindwe kabili ngaphakathi kwe-molecule eyodwa ibeka isizathu esiyisisekelo sokuthi kungani i-TA05 isetshenziswa ngokuphindaphindiwe ezimbonini eziningi.

Ngokuphathelene nezakhiwo zomzimba, i-TA05 ibonakala njengoketshezi oluthambile oluphuzi kuya konsundu oluthambile ku-25°C. Isixazululo sayo samanzi esingu-1% siyi-alkaline ene-pH esukela ku-9 kuya ku-11. Inani eliphelele le-amine livame ukulawulwa phakathi kuka-110–120 mgKOH/g, umswakama ≤1.0%, umbala kaGardner ≤10, kanti inani le-HLB licishe libe ngu-9. Le HLB isendaweni efanele phakathi kwe-hydrophilicity kanye ne-lipophilicity, okwenza ukuthi incibilike kahle ezigabeni zamafutha ngenkathi ithuthela ezindaweni ezihlangana namanzi kawoyela. Ngakho-ke ifaneleka kwi-W/O emulsification, i-co-emulsification kanye ne-interfacial wetting, kunokuba isebenze njenge-emulsifier elula yamafutha emanzini.

I-feedstock eyodwa ye-tallow amine ingafakwa ethoxylation ibe amamaki alandelanayo anamayunithi angu-2, 5, 10, 15 EO, okuletha izakhiwo ezishintsha kancane kancane. Ukubalwa kwe-EO okuphansi kuletha i-lipophilicity enamandla, inani eliphezulu le-amine kanye nokuncibilika kwamanzi okuphansi; okuqukethwe okuphezulu kwe-EO kuthuthukisa ukuncibilika kwamanzi kanye nokushintsha ukukhetha kwe-emulsifying kuya ezinhlelweni ze-O/W.

Ibanga le-2 EO lincibilika kakhulu ku-oyela, lidinga ukuncibilikiswa kwe-solvent noma ukushisa ukuze kuhlakazeke ngezindlela eziningi. Amabanga anamayunithi e-EO ayi-10 noma ngaphezulu abonisa ukuncibilika kwamanzi okungcono kakhulu kodwa abonisa ukuqina kokuxhumana okubuthakathaka ezinhlelweni ezinama-oyela amaningi, okuqukethwe okuqinile. Amayunithi amahlanu e-EO afinyelela indawo ephakathi nendawo elinganiselayo: agcina izingxenye ezanele ze-lipophilic ukuze zibambelele phezu kwamafutha, i-asphalt kanye nobuso bamaminerali, kuyilapho enekhono eliyisisekelo le-hydrophilic lokusabalalisa ezindaweni zamanzi. Ngezinhlelo zokusebenza ezidinga kokubili i-emulsification kanye ne-adsorption, ukulinganisela i-lipophilicity kanye nokuhlakazeka kwamanzi, leli banga livame ukwenza kangcono kunamabanga kunoma yiliphi icala le-EO spectrum.

Lokho kuchaza nokuthi kungani i-TA05 ibhekwa kabanzi njenge-"formulation connector". Ukuncibilika kwayo emanzini kanye nephuzu lamafu kungalungiswa ngokuxuba nama-analogue aphezulu e-EO, kuyilapho ukusebenza kwe-lipophilic kungakhuliswa ngokuhlanganiswa nezinhlobo ze-low-EO. Ezinhlelweni ezihlanganisiwe, isebenza njengesisekelo sokwakha esiguquguqukayo sokulungiswa kwefomula, ngokuvamile ibaluleke kakhulu njenge-co-component kune-ejenti eyinhloko ezimele.

Ngaphandle kwemikhakha engenhla, ingasetshenziswa njengesithasiselo esilwa nokungaguquguquki kanye nokuthambisa ekucutshungulweni kwezindwangu ngokunamathela ezindaweni zefayibha ngamaqembu e-amine akhiqizwa yi-protonated. Ekuntanteni kwamaminerali, isebenza njengesithasiselo esisekelayo noma esihlakazayo esincike ekufakweni kwe-cationic okuqondisiwe ezindaweni zamaminerali.

Kuma-ethoxylates e-fatty amine, ukuhlangabezana nemingcele yokucaciswa kumane kuyisidingo sokungena. Okulawula ngempela ukuzinza kokwakheka kwamakhasimende okugcina ukusatshalaliswa kwe-EO okunciphile, i-PEG yamahhala elawulwayo kanye nokuqukethwe kwe-EO yamahhala, kanye nombala ozinzile phezu kwesitoreji. Ukusatshalaliswa kwe-EO okubanzi kuzoholela ekushintsheni kwamandla okuhlanganisa kanye nokuncibilika kwamanzi ngisho noma kunamanani afanayo e-amine. Ukwakheka okwenziwe kahle esikalini selabhorethri kuvame ukwehluleka ngesikhathi sokuhlolwa noma sokwandiswa kokukhiqiza okugcwele.

Kwa-Qixuan, izinkomba zokulawula eziyinhloko ze-TA05 zimboza inani le-amine, umswakama, i-pH nombala, ngokuhlolwa okugcwele kwebhetshi kanye nokugcinwa kwesampula ukuze kulandeleke. Ukupakisha okujwayelekile kungu-180 kg ngedrama ngayinye, kuyilapho i-IBC tote kanye nokupakisha kwe-OEM okwenziwe ngokwezifiso kuyatholakala uma kuceliwe.

• [1] Chaza ifasitela le-pH ngaphambi kokuhlolwa kokuhambisana:I-TA05 iziphatha njenge-cationic ngaphansi kwezimo ze-acidic kanye ne-non-ionic ngaphansi kwezimo ze-alkaline. Abalingani bayo abahambisanayo, ukulandelana kokudla kanye nomthamo onconywayo kuhluka kakhulu phakathi kwalezi zindawo ezimbili.
• [2] Gwema ukuxubana ngqo ngobuningi nama-surfactants e-anionic:Uma kuhlanganiswa nezinhlobo ze-anionic, ama-surfactant aphakathi nendawo angewona ama-ionic noma ama-feed sequences ahlukene ayanconywa ukuvimbela ukugcwala okuphezulu kwendawo kanye nokwakheka kokuvimbela.
• [3] Lawula izinga lokushisa lokudla:I-TA05 ine-viscosity ephezulu, ikakhulukazi ngaphansi kwezimo zasebusika ezishisa kakhulu. Ukushisa kufikela cishe ku-60°C ngaphambi kokuthatha umthamo kwenza kube lula ukulinganisa okunembile futhi kuvimbele ukungalingani kwe-emulsification yendawo.

Ukukhetha i-surfactant empeleni ukuthola iphuzu elifanele ngokuhambisana ne-EO tuning curve eqhubekayo. Ubuhle be-TA05 abukho ekusebenzeni okuphezulu endaweni eyodwa, kodwa buthatha leyo ndawo ephakathi evame ukunganakwa ebhalansisa i-lipophilicity kanye ne-hydrophilicity enezidingo eziningi zemakethe ezisebenzayo.

I-Shanghai Qixuan Chemical Technology Co., Ltd. inikeza uchungechunge oluphelele lwezinhlobo ze-tallow amine polyoxyethylene ether. Sikulungele ukuhlinzeka ngezinhlobo ze-EO ezenzelwe wena kanye nokusekelwa kobuchwepheshe bezicelo zobungcweti okuhambisana nezidingo zakho ezithile zokwakheka.
