Umahluko kwiYunithi ye-EO ngamanani ambalwa, Kutheni ukusebenza kweFomulation kutshintsha kakhulu? — Ukuqonda uKhetho lwe-Fatty Amine Ether ngeQixuan TA05

Ngexesha leentlanganiso zokukhetha i-surfactant, umngeni oqhelekileyo uhlala uvela: ii-ether ezimbini ze-fatty amine polyoxyethylene ezinee-ether ezimbini ezahlukeneyo kwiiyunithi ze-ethylene oxide (EO) kunye neethegi zexabiso ezifanayo zinokuzisa iziphumo ezahlukeneyo kakhulu xa zifakwe kwiifomyula ezisebenzayo. Uzinzo lwe-emulsion, i-viscosity yenkqubo kunye nombala wemveliso ogqityiweyo ziya kutshintsha ngokubonakalayo. Ekukhonzeni abathengi kuzo zonke iindawo zokucoca, i-oyile, i-agrochemical emulsification, i-asphalt, i-mineral processing kunye namanye amacandelo, iqela lobuchwephesha leShanghai Qixuan Chemical Technology Co., Ltd. lihlala libuzwa umbuzo ophambili: ungayikhetha njani inombolo ye-EO efanelekileyo?

TA05, oko kukuthi i-tallow amine polyoxyethylene (5) ether, inika isisombululo esimeleyo kulo mbuzo. Ayilandeli ukusebenza okugqithisileyo kwisalathisi esinye, kodwa ifumana indawo yayo ethembekileyo kuluhlu olubanzi lweenkqubo zesicelo ezahlukeneyo kakhulu.

I-TA05 yenziwe nge-ethoxylation ye-tallow amine yendalo ene-5 EO units, i-CAS No. 61791-26-2. Icandelo layo le-hydrophobic liqulathe imixokelelwane emide ye-C16–C18 alkyl, ngelixa inxalenye ye-hydrophilic igalelwa ngokudibeneyo zii-5 EO units kunye neqela le-protonable amine.

Olu lwakhiwo lukhethekileyo lusinika ubume obubini bokusebenza. Phantsi kweemeko ezingathathi cala okanye ze-alkaline, sisebenza njenge-surfactant engeyiyo i-ionic, sifezekisa i-emulsification kunye nokusasazwa ngokufuthwa kwe-EO chains. Kwiindawo ezine-asidi, iqela le-amine liyavela kwaye lithwala iitshaja ezintle, libonisa iimpawu ze-cationic surfactant ezinobuhlobo obuqinileyo be-adsorption kwi-substrates ezine-negative charged substrates kuquka imiphezulu yesinyithi, iiminerali, iifayibha kunye namasuntswana e-asphalt. Le ndlela yokusebenza kabini kwi-molecule enye ibeka isizathu esisisiseko sokuba i-TA05 isetyenziswe ngokuphindaphindiweyo kumashishini amaninzi.

Ngokweempawu zomzimba, i-TA05 ibonakala njengolwelo oluthambileyo olutyheli ukuya komdaka kwi-25°C. Isisombululo sayo samanzi esiyi-1% sine-alkaline kunye ne-pH ukusuka kwi-9 ukuya kwi-11. Ixabiso elipheleleyo le-amine lihlala lilawulwa phakathi kwe-110–120 mgKOH/g, ukufuma ≤1.0%, umbala weGardner ≤10, kwaye ixabiso le-HLB limalunga ne-9. Le HLB ihleli ngqo kumda phakathi kwe-hydrophilicity kunye ne-lipophilicity, okwenza ukuba inyibilike kakuhle kwizigaba zeoyile ngelixa ifudukela kwiindawo ze-oyile-water. Ke ngoko ifanelekile kwi-W/O emulsification, i-co-emulsification kunye ne-interfacial wetting, endaweni yokusebenza njenge-oil-in-water emulsifier elula.

I-feedstock enye ye-tallow amine inokufakelwa kwi-ethoxylation ibe zii-serial grades ezinee-2, 5, 10, 15 EO units, nto leyo enika iipropati ezahlukeneyo kancinci kancinci. Ukubalwa kwe-EO okuphantsi kuzisa i-lipophilicity enamandla, ixabiso eliphezulu le-amine kunye nokunyibilika kwamanzi okuphantsi; umxholo ophezulu we-EO uphucula ukunyibilika kwamanzi kunye nokutshintsha ukhetho lwe-emulsifying ukuya kwiinkqubo ze-O/W.

I-2 EO grade inyibilika kakhulu kwioyile, ifuna ukunyibilikiswa kwe-solvent okanye ukufudumeza ukuze isasazeke kwiifomyula ezininzi. Amanqanaba aneeyunithi ze-EO ezili-10 nangaphezulu abonisa ukunyibilika kwamanzi okungcono kakhulu kodwa abuthathaka kwi-interfacial affinity kwiinkqubo zeoyile ephezulu, ezinomxholo oqinileyo. Iiyunithi ezintlanu ze-EO zifikelela kumhlaba ophakathi olinganiselayo: igcina amacandelo e-lipophilic aneleyo okubambelela kwioyile, i-asphalt kunye nomphezulu weeminerali, okwangoku inamandla asisiseko e-hydrophilic okusasaza kwiindawo zamanzi. Kwiizicelo ezifuna zombini i-emulsification kunye ne-adsorption, ukulinganisela i-lipophilicity kunye nokusasazeka kwamanzi, eli nqanaba lihlala liphumelela kumanqanaba kuwo omabini amacala e-EO spectrum.

Oko kuchaza isizathu sokuba i-TA05 ithathwa ngokubanzi njenge "sixhobo sokudibanisa ifomyula". Ukunyibilika kwayo emanzini kunye nendawo yayo yelifu kunokulungiswa ngokudibanisa nee-analogues eziphezulu ze-EO, ngelixa ukusebenza kwe-lipophilic kunokwandiswa ngokudibanisa nee-variants eziphantsi ze-EO. Kwiinkqubo ezihlanganisiweyo, isebenza njengebhloko yokwakha eguquguqukayo yokulungelelanisa ifomyula, edla ngokuba luncedo ngakumbi njenge-co-component kune-arhente eyintloko ezimeleyo.

Ngaphandle kwala macandelo angentla, inokusetyenziswa njengesongezo esichasene nokungashukumiyo kunye nokuthamba ekucutshungulweni kwelaphu ngokufunxa kwiindawo zefayibha ngokusebenzisa amaqela e-amine aprotonated. Kwi-mineral flotation, isebenza njenge-collector assistant okanye i-dispersant exhomekeke kwi-directional cationic adsorption kwiindawo zeminerali.

Kwi-fatty amine ethoxylates, ukuhlangabezana nemigangatho yeenkcukacha yimfuneko yokungena kuphela. Okulawula ngokwenene uzinzo lwefomyula kubathengi bokugqibela kukusasazwa kwe-EO okuncinci, i-PEG elawulwayo yasimahla kunye nomxholo we-EO wasimahla, kunye nombala ozinzileyo phezu kwendawo yokugcina. Ukusasazwa kwe-EO ebanzi kuya kukhokelela ekutshintsheni kwamandla okuxuba kunye nokunyibilika kwamanzi nokuba kunezinto ezifanayo ze-amine. Iifomyula ezilungiselelwe kwisikali selabhoratri zivame ukungaphumeleli ngexesha lovavanyo okanye ukwandiswa kwemveliso epheleleyo.

KwiQixuan, izalathi zolawulo oluphambili lwe-TA05 zigubungela ixabiso le-amine, ukufuma, i-pH kunye nombala, kunye novavanyo olupheleleyo lwebhetshi kunye nokugcinwa kwesampuli ukuze kulandeleke. Ukupakisha okuqhelekileyo yi-180 kg ngedrama, ngelixa i-IBC tote kunye nokupakisha okwenziwe ngokwezifiso kwe-OEM kufumaneka xa kuceliwe.

• [1] Chaza iwindow ye-pH ngaphambi kovavanyo lokuhambelana:I-TA05 isebenza njenge-cationic phantsi kweemeko ze-asidi kunye ne-nonionic phantsi kweemeko ze-alkaline. Amaqabane ayo ahambelanayo, ulandelelwano lokutya kunye nomthamo ocetyiswayo wahlukile kakhulu phakathi kwezi ndawo zimbini.
• [2] Kuphephe ukuxuba ngokuthe ngqo izinto ezisetyenziswa kwi-anionic surfactants:Xa zidityaniswe neentlobo ze-anionic, ii-surfactants eziphakathi ezingezizo ze-ionic okanye iindlela zokutya ezahlukeneyo ziyacetyiswa ukuthintela uxinano oluphezulu lwendawo kunye nokwakheka ngokukhawuleza.
• [3] Ubushushu bokutya boLawulo:I-TA05 ine-viscosity ephezulu, ingakumbi phantsi kweemeko zasebusika ezishushu kakhulu. Ukufudumeza ukuya kuthi ga kwi-60°C ngaphambi kokuba idosi inike amandla ekulinganiseni ngokuchanekileyo kwaye kuthintela ukungalingani kwe-emulsification yendawo.

Ukukhetha i-surfactant ngokuyintloko kukufumana indawo efanelekileyo kwi-EO tuning curve eqhubekayo. Inzuzo ye-TA05 ayixhomekekanga ekusebenzeni okuphezulu kwipropati enye, kodwa ithatha loo ndawo iphakathi ehlala ingahoywayo elinganisa i-lipophilicity kunye ne-hydrophilicity kunye neemfuno ezininzi zemarike ezisebenzayo.

IShanghai Qixuan Chemical Technology Co., Ltd. ibonelela ngothotho olupheleleyo lweeklasi ze-tallow amine polyoxyethylene ether. Sikulungele ukubonelela ngeendidi ze-EO ezenzelwe wena kunye nenkxaso yobuchwephesha yesicelo esihambelana neemfuno zakho ezithile zokwenziwa.
