Kusiyana kwa EO Unit ndi Manambala Ochepa, Nchifukwa Chiyani Magwiridwe A Ntchito Amasiyana Kwambiri? — Kumvetsetsa Kusankha kwa Fatty Amine Ether ndi Qixuan TA05

Pamisonkhano yosankha zinthu zopangidwa ndi surfactant, vuto lofala nthawi zambiri limabwera: ma ether awiri a fatty amine polyoxyethylene omwe ali ndi kusiyana pang'ono kwa mayunitsi a ethylene oxide (EO) ndi mitengo yofanana amatha kupereka zotsatira zosiyana kwambiri akaphatikizidwa mu njira zogwirira ntchito. Kukhazikika kwa emulsion, kukhuthala kwa dongosolo komanso mtundu wa chinthu chomalizidwa zimasintha kwambiri. Potumikira makasitomala m'malo oyeretsera, malo opaka mafuta, agrochemical emulsification, asphalt, mineral processing ndi magawo ena, gulu laukadaulo la Shanghai Qixuan Chemical Technology Co., Ltd. nthawi zambiri limafunsidwa funso limodzi lofunika: momwe mungasankhire nambala yoyenera ya EO?

TA05, yomwe ndi tallow amine polyoxyethylene (5) ether, imapereka yankho loyimira funsoli. Siligwiritsa ntchito bwino kwambiri pa chizindikiro chimodzi, koma limapeza malo ake odalirika m'njira zosiyanasiyana zogwiritsira ntchito.

TA05 imapangidwa ndi ethoxylation ya amine yachilengedwe yokhala ndi mayunitsi 5 a EO, CAS No. 61791-26-2. Gawo lake lopanda madzi limapangidwa ndi maunyolo atali a C16–C18 alkyl, pomwe gawo lopanda madzi limaphatikizidwa pamodzi ndi mayunitsi asanu a EO ndi gulu la amine lotchedwa protonatable amine.

Kapangidwe kake kapadera kameneka kamapatsa mawonekedwe awiri ogwira ntchito. Mu mikhalidwe yopanda mbali kapena ya alkaline, imagwira ntchito ngati surfactant yopanda ionic, yomwe imakwaniritsa emulsification ndi dispersion kudzera mu hydration ya unyolo wa EO. M'malo okhala ndi acidic, gulu la amine limapangidwa ndi proton ndipo limakhala ndi ma positive charges, kusonyeza makhalidwe a cationic surfactant okhala ndi mphamvu yamphamvu yoyamwa ku substrates zomwe zili ndi negative charge kuphatikizapo pamwamba pa zitsulo, mchere, ulusi ndi tinthu ta asphalt. Njira yogwirira ntchito iwiriyi mkati mwa molekyulu imodzi ndiyo chifukwa chachikulu chomwe TA05 imagwiritsidwira ntchito mobwerezabwereza m'mafakitale osiyanasiyana.

Ponena za makhalidwe ake enieni, TA05 imawoneka ngati madzi okhuthala achikasu mpaka bulauni pa 25°C. Yankho lake lamadzi la 1% ndi la alkaline ndipo pH yake imayambira pa 9 mpaka 11. Mtengo wonse wa amine nthawi zambiri umayendetsedwa pakati pa 110–120 mgKOH/g, chinyezi ≤1.0%, mtundu wa Gardner ≤10, ndipo mtengo wa HLB ndi pafupifupi 9. HLB iyi ili pakati pa hydrophilicity ndi lipophilicity, zomwe zimathandiza kuti isungunuke bwino m'magawo amafuta pamene ikusamukira ku malo olumikizirana ndi madzi amafuta. Chifukwa chake ndi yoyenera ku emulsification ya W/O, co-emulsification ndi interfacial wetting, m'malo mogwira ntchito ngati emulsifier yosavuta ya mafuta-mu-madzi.

Katundu wa amine imodzi ya tallow amatha kusinthidwa kukhala ma serial grades okhala ndi mayunitsi 2, 5, 10, 15 EO, zomwe zimapangitsa kuti pang'onopang'ono zinthu zisinthe. Kuchuluka kwa EO kumabweretsa lipophilicity yolimba, kuchuluka kwa amine komanso kusungunuka kochepa kwa madzi; kuchuluka kwa EO kumawonjezera kusungunuka kwa madzi ndikusuntha kukonda kwa emulsifying kupita ku machitidwe a O/W.

Gulu lachiwiri la EO limasungunuka kwambiri mu mafuta, limafuna kusungunuka kwa solvent kapena kutentha kuti lifalikire m'njira zambiri. Magulu okhala ndi mayunitsi 10 kapena kuposerapo a EO amasonyeza kusungunuka bwino kwa madzi koma kufooka kwa mgwirizano wa interfacial mu machitidwe okhala ndi mafuta ambiri, olimba kwambiri. Mayunitsi asanu a EO amafika pamtunda wapakati wolinganizika: amasunga magawo okwanira a lipophilic kuti azingike pa mafuta, phula ndi mineral pamwamba, pomwe ali ndi mphamvu yoyambira ya hydrophilic yofalikira m'madzi. Pa ntchito zomwe zimafuna emulsification ndi ma adsorption, kulinganiza lipophilicity ndi kufalikira kwa madzi, gululi nthawi zambiri limachita bwino kuposa mayunitsi onse a EO spectrum.

Izi zikufotokozanso chifukwa chake TA05 imaonedwa kwambiri ngati "cholumikizira chopangira". Kusungunuka kwa madzi ndi malo ake amtambo zimatha kusinthidwa posakaniza ndi ma analogues apamwamba a EO, pomwe magwiridwe antchito a lipophilic amatha kukulitsidwa pophatikiza ndi mitundu yotsika ya EO. Mu makina ophatikizika, imagwira ntchito ngati maziko osinthika osinthira kapangidwe kake, nthawi zambiri imakhala yofunika kwambiri ngati gawo limodzi kuposa choyimira chokha.

Kupatula magawo omwe ali pamwambapa, ingagwiritsidwe ntchito ngati chowonjezera choletsa kusinthasintha komanso chofewa mu kukonza nsalu mwa kumata pamwamba pa ulusi kudzera m'magulu a amine omwe ali ndi protonated. Mu kuyandama kwa mchere, imagwira ntchito ngati chosonkhanitsa chothandizira kapena chotulutsa madzi pogwiritsa ntchito njira yolumikizira cationic pamwamba pa mchere.

Pa ma ethoxylates amafuta a amine, kukwaniritsa malire ofunikira ndi chinthu chofunikira kwambiri. Chomwe chimayang'anira kukhazikika kwa kapangidwe ka mankhwala kwa makasitomala omaliza ndi kugawa kochepa kwa EO, PEG yaulere yolamulidwa komanso kuchuluka kwa EO kwaulere, komanso mtundu wokhazikika pakusungira. Kugawa kwakukulu kwa EO kumabweretsa kusinthasintha kwa mphamvu ya emulsifying ndi kusungunuka kwa madzi ngakhale ndi ma amine ofanana. Mafomula okonzedwa bwino pamlingo wa labu nthawi zambiri amalephera panthawi yoyeserera kapena yokwanira yopanga.

Ku Qixuan, zizindikiro zoyendetsera TA05 zimaphimba kuchuluka kwa amine, chinyezi, pH ndi mtundu, ndi mayeso athunthu a batch ndi kusunga zitsanzo kuti zitsatidwe. Mapaketi wamba ndi 180 kg pa ng'oma iliyonse, pomwe tote ya IBC ndi ma package a OEM okonzedwa mwamakonda amapezeka mukawapempha.

• [1] Fotokozani zenera la pH musanayese kuwunika momwe zinthu zilili:TA05 imagwira ntchito ngati cationic pakakhala acidic komanso nonionic pakakhala alkaline. Mabwenzi ake ogwirizana, njira yodyetsera ndi mlingo woyenera zimasiyana kwambiri pakati pa malo awiriwa.
• [2] Pewani kusakaniza mwachindunji ndi ma anionic surfactants:Mukaphatikizana ndi mitundu ya anionic, ma surfactants apakatikati omwe si a ionic kapena njira zosiyana zodyetsera zimalimbikitsidwa kuti mupewe kuchulukana kwambiri m'deralo ndi kupanga mwachangu.
• [3] Kulamulira kutentha kwa kudya:TA05 ili ndi kukhuthala kwakukulu, makamaka m'nyengo yozizira yotentha kwambiri. Kutenthetsa mpaka pafupifupi 60°C musanapereke mlingo kumathandiza kuyeza molondola ndipo kumaletsa emulsification yapafupi.

Kusankha kwa surfactant kwenikweni ndikupeza malo abwino kwambiri motsatira njira yopititsira patsogolo EO tuning curve. Ubwino wa TA05 suli mu ntchito yabwino kwambiri pa chinthu chimodzi, koma umakhala pakati pa malo omwe nthawi zambiri sawonedwa bwino poyesa lipophilicity ndi hydrophilicity ndi zofunikira zambiri pamsika.

Shanghai Qixuan Chemical Technology Co., Ltd. imapereka mitundu yonse ya tallow amine polyoxyethylene ether. Tili okonzeka kupereka mitundu yosiyanasiyana ya EO komanso chithandizo chaukadaulo chogwirizana ndi zomwe mukufuna.
