I-I-Lauryl Alcohol Ethoxylate (AEO), eyaziwa nangokuthi i-Fatty Alcohol Ethoxylate okanye i-Alcohol Ethoxylate (i-CAS No. 9002-92-0), i-nonionic surfactant eveliswa yi-ethoxylating fatty alcohols nge-ethylene oxide. Inombolo emva kwe-AEO ibonisa inani eliphakathi kweeyunithi ze-ethylene oxide - kwaye le nombolo inefuthe elichanekileyo kwindlela i-surfactant eziphatha ngayo ekuqulunqweni.
Abathengi bahlala bethandabuza phakathi kwe-AEO-3, i-AEO-7 kunye ne-AEO-9 kuba ibakala ngalinye linomlinganiselo ohlukeneyo wexabiso le-HLB, ukunyibilika kunye nokusebenza kwesicelo. Ukhetho alukho nje malunga nokuba yeyiphi "engcono." Ukukhetha ibakala elingalunganga kunokuchaphazela ukusebenza kakuhle kokucoca, ukuziphatha kwegwebu, indawo yefu kunye nokuhambelana nezinye izithako kwinkqubo.
Ukwenza uthelekiso lucace ngakumbi, iDotachem ishwankathele umahluko omkhulu phakathi kwala mabanga mathathu kunye nezicelo apho ngalinye lisetyenziswa ngokuqhelekileyo.
Ukuqonda amaBanga e-AEO nge-HLB
I-HLB inceda ukucacisa ukuba kutheni amabakala e-AEO aziphatha ngendlela eyahlukileyo kwiinkqubo zeoli kunye namanzi. Njengoko inani le-EO litshintsha, ibhalansi phakathi kobudlelwane beoli kunye nokuhambelana kwamanzi kutshintsha kunye nayo.
Amabanga aneeyunithi ezimbalwa ze-EO, ezifana ne-AEO-3, ahlala esondele kwisigaba seoli kwaye ahlala esetyenziselwa i-emulsification. I-AEO-7 ihlala kufuphi nephakathi, ngelixa i-AEO-9 i-hydrophilic kwaye kulula ukuyisebenzisa kwiinkqubo zokucoca ngamanzi.
Lo mahluko weHLB yeyona nto iqhuba ukwahlulwa kwesicelo phakathi kwala mabanga mathathu.
Xa i-AEO-3 yenza ingqiqo ngakumbi
Phakathi kwala mabanga mathathu, i-AEO-3 yeyona nto ijoliswe kwioli. I-HLB yayo ephantsi iyenza ilunge ngakumbi xa umsebenzi ophambili u-emulsification kunokucoca.
Kuhlala kuxoxwe ngayo malunga nokugxilwa kwezolimo emulsifiable, ulwelo lwesinyithi kunye nezinye iinkqubo eziqulethe i-oyile yezimbiwa okanye i-oyile yokwenziwa. Kwezi zicelo, i-surfactant idinga ukunceda isigaba se-oyile sisasazeke emva kokuba amanzi esongeziweyo, ngaphandle kokwenza inkqubo ibe namagwebu ngokugqithisileyo okanye inyibilike kakhulu emanzini.
I-AEO-3 ke idla ngokuvavanywa kunye nohlobo lweoyile, iphakheji ye-emulsifier kunye nokuzinza kwe-emulsion efunekayo. Igama lebakala lodwa alanelanga ukuqikelela ukuba inkqubo egqityiweyo iya kuziphatha njani.
Apho i-AEO-7 isetyenziswa ngokuqhelekileyo
I-AEO-7 ibonelela ngokulinganayo ngakumbi phakathi kokumanzisa, ukufakwa kwe-emulsification kunye nokucoca. Oku kuyenza ibe luncedo ekucoceni kwimizi-mveliso kunye nokulungiswa kwamalaphu, ngakumbi apho inkqubo idinga ukumanzisa okusebenzayo kodwa akufuneki kuvelise amagwebu amaninzi kakhulu.
Imizekelo eqhelekileyo ibandakanya abacoci bomhlaba oqinileyo kunye nezixhobo, izinto ezincedisayo zokukhuhla amalaphu, iimveliso zokucoca isitshizi kunye nezinye iinkqubo zeCIP. Kule meko, abathengi bavame ukujonga isantya sokumanzisa, ukususwa kweoli, inqanaba le-foam kunye nokusebenza kwiqondo lokushisa langempela.
I-AEO-7 ikwaqwalaselwa kwezinye iiprojekthi zokutshintshwa kwe-NPE. Uluhlu olufanayo lwe-HLB lunokuyenza ibe yindawo yokuqala eluncedo, nangona indawo yefu kunye nokusebenza kwe-emulsification kusafuneka kuhlolwe kwinkqubo yomthengi.
I-AEO-9: Xa Ukuhambelana Kwamanzi Okungcono Kudingeka
I-AEO-9 i-hydrophilic ngaphezu kwe-AEO-3 kunye ne-AEO-7, ngoko ikhethwa ngokuqhelekileyo kwi-detergent yamanzi kunye neemveliso zokucoca.
Ingasetyenziswa kwizinto zokucoca iimpahla, izicoci zenjongo jikelele, iimveliso zokuvasa kwimizi-mveliso kunye ne-emulsion polymerization. Ukuhambelana ngcono kwamanzi kunokuphucula ukusasazwa kunye nokucaca kwemveliso, ngakumbi xa imathiriyeli ifuna ukusebenza kumanqanaba ahlukeneyo okuxutywa.
Kwiinkqubo ezininzi ezisekelwe emanzini, i-AEO-9 yibakala elisebenzayo lokuvavanya kuqala. Ukhetho lokugqibela lusenokutshintsha emva kokujonga i-foam, i-viscosity, i-cloud point kunye nokuhambelana nezinye i-surfactants ekuqulunqweni.
Iimpawu eziphambili zokuQinisekisa phambi kokufunwa
Xa kufunwa amabanga e-AEO, abathengi baqinisekisa ukuba:
Kubathengi abatshintshayo ukusuka kwi-NPE ukuya kumabanga e-AEO, kukwafanelekile ukuvavanya indawo yelifu kunye nokusebenza kwe-emulsification kwifomula yokwenyani ngaphambi kokuba bazibophelele kwii-odolo ezininzi, kuba i-AEO kunye ne-NPE zingasoloko zisebenza ngokufanayo kumaxabiso alinganayo e-HLB.
Ukufumana i-AEO evela eDotachem
IDotachem ibonelela ngeLauryl Alcohol Ethoxylate amabanga ukusuka kwi-AEO-1 ukuya kwi-AEO-9 yokucoca kwimizi-mveliso, amalaphu, ezolimo kunye nokusebenza kwesinyithi. Olu chungechunge lubonisa umbala olawulwayo, umxholo wokufuma ophantsi kunye noluhlu lwe-pH oluzinzile lwe-6.0-7.0, kunye namaxabiso e-hydroxyl ahambelana namabakala ahlukeneyo e-EO.
Iimveliso zi-REACH ziyahambelana kwaye zibonelelwa nge-COA, TDS kunye ne-SDS. Iisampulu zasimahla ziyafumaneka ukuze zivavanywe ibakala phambi kokuthenga isambuku.
Kubathengi abathelekisayoNonylphenol Ethoxylate(NPE) kunye namabakala e-AEO, iDotachem inokuxhasa ukukhethwa kwemveliso, ukulinganisa ibakala kunye nokuhlelwa kwesampuli ngokusekelwe kwiimfuno ze-HLB, iimeko zesicelo kunye neemfuno zemarike ekujoliswe kuyo.
Njengomthengisi wemichiza eyomileyo eTshayina, iDotachem ikwabonelela ngezinto ezinxulumene ne-surfactants kunye nezixhobo zepolyether, kubandakanya.Alkyl Polyglucoside(APG),Polyethylene Glycol(PEG),Polypropylene Glycol(PPG) kunyeI-I-Octylphenol Ethoxylate(OPE). Ezi mveliso zixhasa iimfuno ezahlukeneyo ekucoceni, emulsification, ukumanzisa kunye nokusetyenzwa kwemizi-mveliso, ukunika abathengi iinketho ezininzi zokukhetha imveliso kunye nokukhangela okudityanisiweyo.
Qhagamshelana neDotachem malunga neenkcukacha zemveliso, iisampuli kunye nenkxaso yokukhangela evela eChina.
