I-I-Lauryl Alcohol Ethoxylate (AEO), eyaziwa nangokuthi i-Fatty Alcohol Ethoxylate noma i-Alcohol Ethoxylate (i-CAS No. 9002-92-0), i-nonionic surfactant ekhiqizwa i-ethoxylating fatty alcohols nge-ethylene oxide. Inombolo engemva kwe-AEO ikhombisa inombolo emaphakathi yamayunithi e-ethylene oxide - futhi le nombolo inomthelela oqondile wokuthi i-surfactant iziphatha kanjani ekwakhiweni.
Amakhasimende avame ukungabaza phakathi kwe-AEO-3, AEO-7 ne-AEO-9 ngoba ibanga ngalinye linebhalansi ehlukile yenani le-HLB, ukunyibilika nokusebenza kohlelo lokusebenza. Ukukhetha akukhona nje ukuthi iyiphi “engcono”. Ukukhetha ibanga elingalungile kungase kuthinte ukusebenza kahle kokuhlanza, ukuziphatha kwegwebu, indawo yefu kanye nokuhambisana nezinye izithako ohlelweni.
Ukwenza isiqhathaniso sicace kakhudlwana, i-Dotachem ifinyeze umehluko omkhulu phakathi kwala mabanga amathathu kanye nezinhlelo zokusebenza lapho ngalinye lisetshenziswa kakhulu khona.
Ukuqonda Amabanga e-AEO Nge-HLB
I-HLB isiza ukuchaza ukuthi kungani amamaki e-AEO eziphatha ngendlela ehlukile kumasistimu asekelwe kuwoyela namanzi. Njengoba inombolo ye-EO ishintsha, ibhalansi phakathi kokuhlangana kwamafutha nokuhambisana kwamanzi kuyashintsha nayo.
Amabanga anamayunithi e-EO ambalwa, njenge-AEO-3, ahlala eseduze nesigaba sikawoyela futhi avame ukusetshenziselwa i-emulsification. I-AEO-7 ihlala eduze nendawo emaphakathi, kuyilapho i-AEO-9 ine-hydrophilic futhi kulula ukuyisebenzisa ezinhlelweni zokuhlanza ezisekelwe emanzini.
Lo mehluko we-HLB yiwo oqhuba ukuhlukaniswa kwesicelo phakathi kwala mabanga amathathu.
Lapho i-AEO-3 Izwakala Kakhudlwana
Kula mabanga amathathu, i-AEO-3 iyona egxile kakhulu kuwoyela. I-HLB yayo ephansi iyenza ilingane kangcono uma umsebenzi oyinhloko uwukwenza i-emulsification kunokuhlanza.
Kuvame ukuxoxwa ngakho mayelana nokugxilwa kwezolimo okumulsifiable, uketshezi lwensimbi nezinye izinhlelo eziqukethe uwoyela wamaminerali noma uwoyela wokwenziwa. Kulezi zinhlelo zokusebenza, i-surfactant idinga ukusiza isigaba sikawoyela sihlakazeke ngemva kokwengezwa kwamanzi, ngaphandle kokwenza isistimu ibe negwebu ngokweqile noma inyibilike emanzini ngokweqile.
Ngakho-ke i-AEO-3 ivamise ukuhlolwa kanye nohlobo lwamafutha, iphakheji ye-emulsifier kanye nokuzinza kwe-emulsion okudingekayo. Igama lebanga lilodwa alanele ukubikezela ukuthi uhlelo oluqediwe luzoziphatha kanjani.
Lapho I-AEO-7 Isetshenziswa Ngokujwayelekile
I-AEO-7 inikeza ibhalansi elinganayo phakathi kokumanzisa, i-emulsification kanye ne-detergency. Lokhu kwenza kube usizo ekuhlanzeni kwezimboni nasekucutshungulweni kwezindwangu, ikakhulukazi lapho isistimu idinga ukumanziswa okuphumelelayo kodwa akufanele ikhiphe igwebu eliningi.
Izibonelo ezijwayelekile zifaka izihlanzi zobuso obuqinile nemishini, izinsiza zokukhuhla izindwangu, imikhiqizo yokuhlanza isifutho nezinye izinhlelo ze-CIP. Kulezi zimo, amakhasimende athambekele ekubhekeni isivinini sokumanzisa, ukususwa kukawoyela, izinga legwebu nokusebenza ezingeni lokushisa langempela lokusebenza.
I-AEO-7 iphinde icatshangelwe kwamanye amaphrojekthi okushintsha i-NPE. Ububanzi obufanayo be-HLB bungayenza isiqalo esiwusizo, nakuba iphoyinti lefu nokusebenza kwe-emulsification kusadingeka ukuthi kuhlolwe kusistimu yekhasimende uqobo.
I-AEO-9: Lapho Ukuhambisana Kwamanzi Okungcono Kudingeka
I-AEO-9 ine-hydrophilic kakhulu kune-AEO-3 ne-AEO-7, ngakho-ke ikhethwa kakhulu okokuhlanza okusekelwe emanzini kanye nemikhiqizo yokuhlanza.
Ingasetshenziselwa okokuhlanza izingubo, okokuhlanza inhloso evamile, imikhiqizo yokuwasha yezimboni kanye ne-emulsion polymerization. Ukuhambisana okungcono kwamanzi kungase kuthuthukise ukuhlakazeka nokucaca komkhiqizo, ikakhulukazi uma okokusebenza kudinga ukusebenza kumazinga ahlukene wokuhlanjululwa.
Ezinhlelweni eziningi ezisekelwe emanzini, i-AEO-9 iyibanga elisebenzayo okufanele lihlolwe kuqala. Inketho yokugcina ingase ishintshe ngemva kokuhlola igwebu, i-viscosity, indawo yefu kanye nokuhambisana namanye ama-surfactants ekwakhiweni.
Izinkomba Ezibalulekile Okufanele Uziqinisekise Ngaphambi Kokutholwa
Lapho uthola amamaki e-AEO, abathengi ngokuvamile bayaqinisekisa:
Kumakhasimende ashintsha ukusuka ku-NPE ukuya kumabanga e-AEO, kufanelekile ukuhlola indawo yefu nokusebenza kwe-emulsification ekwakhiweni kwangempela ngaphambi kokuzibophezela kuma-oda amaningi, njengoba i-AEO ne-NPE zingahlali zisebenza ngokufanayo ngamavelu alinganayo e-HLB.
Ukuthola i-AEO kusuka ku-Dotachem
I-Dotachem ihlinzeka nge-Lauryl Alcohol Ethoxylate amabanga ukusuka ku-AEO-1 kuya ku-AEO-9 ukuze kuhlanzwe izimboni, izindwangu, ezolimo kanye nezicelo zensimbi. Uchungechunge lubonisa umbala olawulwayo, umswakama ophansi kanye nebanga le-pH elizinzile lika-6.0–7.0, elinamanani e-hydroxyl afaniswe namabanga e-EO ahlukene.
Imikhiqizo iyahambisana ne-REACH futhi ihlinzekwa nge-COA, TDS kanye ne-SDS. Amasampula wamahhala ayatholakala ukuze ahlolwe ibanga ngaphambi kokuthenga ngobuningi.
Okwamakhasimende ukuqhathanisaI-I-Nonylphenol Ethoxylate(NPE) kanye namabanga e-AEO, i-Dotachem ingasekela ukukhethwa komkhiqizo, ukufaniswa kwebanga nokuhlelwa kwesampula okusekelwe kuzimfuneko ze-HLB, izimo zohlelo lokusebenza kanye nezidingo zemakethe eziqondiwe.
Njengomphakeli wezinto ezingavuthiwe zamakhemikhali osebenza endaweni eyodwa e-China, i-Dotachem futhi ihlinzeka ngezisetshenziswa ezisetshenziswayo ezihlobene nezinto zokwakha ze-polyether, okuhlanganisaI-I-Alkyl Polyglucoside(APG),I-I-Polyethylene Glycol(I-PEG),I-I-Polypropylene Glycol(PPG) kanyeI-I-Octylphenol Ethoxylate(I-OPE). Le mikhiqizo isekela izidingo ezihlukene ekuhlanzeni, emulsification, ekumanziseni nasekucutshungulweni kwezimboni, enikeza amakhasimende izinketho eziningi zokukhethwa komkhiqizo kanye nokutholakala okuhlanganisiwe.
Xhumana ne-Dotachem ukuze uthole imininingwane yomkhiqizo, amasampula kanye nokwesekwa kokutholakala okuvela e-China.
