Kwikhemikhali entle kunyei-surfactantuthotho lwemizi-mveliso,ii-alkyl dimethyl tertiary amineszisebenza njengezinto eziphambili ezidibanisa iinkqubo ezisezantsi neziphezulu. Iipropati eziphambili zeemveliso ezisezantsi kuquka ii-amine oxides, ii-betaine amphoteric surfactants kunye neetyuwa ze-cationic quaternary ammonium—njengokwenza igwebu, ukuqina, ukuxuba, ukumanzisa kunye nokusebenza kweebhaktheriya—ngokusisiseko zixhomekeke kukusasazwa kwe-carbon chain, ubumsulwa kunye nokuzinza komgangatho we-upstream tertiary amine feedstocks. Ukuguquguquka okuncinci kumlinganiselo we-carbon chain kunokubangela ngokuthe ngqo uthotho lwamanqaku entlungu yemveliso, njenge-foam engaguqukiyo yeemveliso ezigqityiweyo, ukuhluzwa kwenkqubo, ubomi obufutshane beshelufu kunye nokwanda nge‑iimveliso.
IShanghai Qixuan Chemical Technology Co., Ltd. inamava anzulu ekunikezelweni kwezinto ezisetyenziswa njenge-surfactant. Kubathengi abasebenzisa ukucoca iikhemikhali imihla ngemihla, i-asphalt emulsification, izongezo zoshishino, unyango lwamanzi kunye neminye imimandla, sazisa i-**DMA246 mixed alkyl dimethyl tertiary amine**. Le mveliso ine-carbon chain composition elawulwa kakuhle kunye nolawulo olungqongqo lokungcola, kwaye inika ixabiso eliphantsi.‑isisombululo esisebenzayo sezinto eziluhlaza kwiimeko ezahlukeneyo zokwenziwa kwe-surfactant.
I-DMA246 ngumxube odityanisiweyo we-dodecyldimethylamine, i-tetradecyldimethylamine kunye ne-hexadecyldimethylamine. Uluhlu lwayo lokwakheka lulawulwa ngokungqongqo: I-Dodecyldimethylamine (C12DMA, CAS: 112-18-5) ingama-54.0~62.0%; i-Dimethyl(tetradecyl)amine (C14DMA, CAS: 112-75-4) ingama-32.0~38.0%; i-Hexadecyldimethylamine (C16DMA, CAS: 112-69-6) ingama-5.0~9.0%. Ixabiso layo lilonke le-amine lihlala limalunga ne-246 mgKOH/g, apho igama lemveliso i-DMA246 livela khona.
Le mveliso inomxholo ophezulu we-amine ephezulu esebenzayo, kunye nokungcola kwe-amine yokuqala neyesibini okulinganiselweyo kwaye umxholo wokufuma uphantsi. Inciphisa ngempumelelo amathuba okuba neempendulo ezingalindelekanga kubathengi.'i-quaternization, i-oxidation kunye ne-amphoterization synthesis, kwaye inciphisa iimpembelelo ezimbi ze-‑iimveliso ezinombala kunye nevumba leempahla ezigqityiweyo ezisezantsi. Kwiqondo lobushushu eliphakathi, ibonakala njengolwelo olunamafutha olungenambala, olunganyibilikiyo emanzini kodwa oluxutywa ne-ethanol kunye nezinyibilikisi ze-hydrocarbon organic. Inceda ukondla izinto kunye nokuthuthwa kwemibhobho, kwaye iyaziqhelanisa ne-continuous kunye ne-batch synthesis reactors.
Ii-formulators ezininzi zijongene nemida yokusebenza xa zikhetha ii-intermediates ze-tertiary amine ezinee-single carbon chains: i-pure C12 tertiary amine inika i-foam enamandla kodwa i-degeneration effect ebuthathaka, ngelixa i-long‑uthotho lwe-C16 tertiary amine lunika ukuqina okugqwesileyo kodwa amandla angonelanga okufutha kwaye alukho mandla aneleyo‑ukunyibilika kobushushu. I-DMA246 isebenzisa indibaniselwano yetsheyini yekhabhoni elawulwa yi-C12, eyongezwe yi-C14 kunye nenani elincinci le-C16. Ilinganisela ngobuchule amandla okwenza igwebu, ukusebenza kokujiya kunye nokuhla‑uzinzo lobushushu, nto leyo ephula imiqobo yokusebenza kwe-single‑ikhabhoni‑uthotho lwee-amines ze-tertiary kunye nokugcina indawo enkulu yokulungisa uphuhliso lwefomyula.
Kwimichiza yemihla ngemihla kunye namacandelo okucoca amakhaya, i-DMA246 isebenza njengesixhobo esithandwayo sokwenza ii-amine oxides kunye ne-alkyl betaine amphoteric surfactants. Ii-amine oxides ezenziwe nge-oxidation reaction zisetyenziswa kakhulu kwiisepha zokuhlamba izitya, eziqinileyo.‑izicoci zomphezulu, iishampu, izihlambi zomzimba kunye nezihlambi zobuso. Inxalenye ye-C12 inika iifomyula amandla amangalisayo okufutha, ivelisa igwebu elincinci, elicolekileyo kunye ne-detergent enamandla yokususa ngokufanelekileyo umhlaba wegrisi kunye neproteni. Iinxalenye ze-C14 kunye ne-C16 ezincinci zomeleza ukuqina kwenkqubo, zinciphisa umthamo wokuqina ngakumbi kwaye ziphucula ukunyamezela kwefomyula kumanzi aqinileyo.
Kwiinkqubo zokucoca ezithambileyo, ii-amine oxides kunye nee-betaines ezivela kwi-DMA246 azinazo iziphazamiso ezininzi kwaye azihambelani kakuhle nefomyula. Zinokuhlanganiswa nee-surfactants ezingezizo ii-ionic kunye nee-anionic ukwakha iinkqubo zokucoca ezithambileyo. Iimveliso zokugqibela ziyamelana nokuqhekeka phantsi kwe-low low‑indawo yokugcina ubushushu enokuguquguquka okuncinci kwe-viscosity, ihlangabezana neshelufu eqinileyo‑iimfuno zozinzo ezivela kubavelisi beekhemikhali zemihla ngemihla.‑izicoci zegrisi zomsebenzi kwiikhitshi zokupheka kunye nezixhobo ezininzi‑injongo enzima‑izicoci zomphezulu, le nkqubo iphucula ukuhlanganiswa kwe-emulsification kunye nokusasazwa kwamabala eoyile ngelixa igcina i-foam ilawuleka ukuze ilingane necala elahlukileyo.‑sebenzisa iindlela zokucoca.
Kwizinto zokwakha iindlela, i-DMA246 isebenza njengesixhobo esiphambili sokwenziwa kwe-asphalt emulsifier. Emva kokuguqulwa kwe-quaternization, i-DMA246 ivelisa i-cationic asphalt emulsifiers ezifanelekileyo kwi-medium‑setha kwaye ucothe‑seta iinkqubo ze-asphalt emulsion. Ulwakhiwo lwe-carbon chain exutyiweyo ye-C12/C14/C16 luphucula i-hydrophilic‑ixabiso le-lipophilic balance (HLB) lee-emulsifiers, liphucula uzinzo lokusasazeka kwamaconsi e-asphalt emanzini, landisa ixesha lokugcina i-asphalt emulsion kwaye linciphisa umngcipheko we-sedimentation kunye ne-demulsification ngexesha lokugcina.
Kwizicelo zobunjineli ezifana ne-asphalt exutywe ngokubandayo, i-slurry seal kunye ne-micro‑Umphezulu, ii-emulsifiers ezivela kwi-DMA246 ziphucula ukunamathelana phakathi kwe-asphalt kunye nee-aggregates, zonyusa amandla kunye nokumelana nomonakalo wamanzi kwindlela eyenziweyo, kwaye zixhasa indawo engqongileyo‑ukwakhiwa kobushushu ukunciphisa ukusetyenziswa kwamandla okwakha kunye neendleko zeprojekthi eziphantsi. Xa kuthelekiswa nee-asphalt emulsifiers ezenziwe nge-single‑ikhabhoni‑ii-amines ze-tertiary ze-chain, ii-derivatives ze-DMA246 zibonisa ukusebenza okuzinzileyo kwe-emulsion phantsi kotshintsho olukhulu lobushushu ngexesha lokwakhiwa kwaye zandisa ifestile yokwakha enokwenzeka.
Izongezo zoshishino kunye nonyango lwamanzi zimele enye indawo ebalulekileyo yesicelo se-DMA246. Iityuwa ze-ammonium ze-quaternary eziveliswa yi-quaternization ye-DMA246 zingasetyenziswa njengezinto zokuthambisa ilaphu, ii-biocides kunye nezithinteli zokubola kwesinyithi. Ekugqityweni kwelaphu, iimveliso ze-quaternized zinamathela kwiindawo zefayibha, zinciphisa ukungqubana phakathi kweefayibha kwaye zinike ukuthamba kunye neempawu ze-antistatic kwilaphu. Kwinkqubo zamanzi ezijikelezayo zamanzi apholileyo kunye ne-oyile, zithintela ukukhula kweentsholongwane kwaye zenze ifilimu yokukhusela enamathelayo kwisinyithi sekhabhoni nakwezinye iintsimbi ukuze kuthintelwe ukubola kwezixhobo.
Ngaphezu koko, i-DMA246 ingasetyenziswa ekuhlanganiseni ii-mineral flotation agents, ii-raber release agents kunye ne-fertilizer anti-‑ii-caking agents. Iintambo zayo ezinde ze-alkyl zibonelela ngomsebenzi olungileyo wokudibanisa ubuso ukuze kwaneliswe iimfuno zophuhliso lokongeza kwiindawo ezininzi zoshishino.
