Qhov Sib Txawv ntawm EO Chav Los Ntawm Ob Peb Tus lej, Vim Li Cas Kev Ua Haujlwm ntawm Cov Qauv Thiaj Li Txawv Txawv? — Nkag Siab Txog Kev Xaiv Fatty Amine Ether nrog Qixuan TA05

Thaum lub rooj sib tham xaiv cov surfactant, feem ntau muaj teeb meem tshwm sim: ob lub roj amine polyoxyethylene ethers nrog tsuas yog qhov sib txawv me ntsis hauv ethylene oxide (EO) units thiab cov nqi zoo sib xws tuaj yeem xa cov txiaj ntsig sib txawv thaum koom nrog rau hauv cov qauv siv tau. Qhov ruaj khov ntawm emulsion, viscosity ntawm lub cev thiab txawm tias cov xim tiav lawm yuav hloov pauv pom tseeb. Hauv kev pabcuam cov neeg siv khoom thoob plaws kev ntxuav, roj av, agrochemical emulsification, asphalt, kev ua cov minerals thiab lwm yam kev lag luam, pab pawg neeg ua haujlwm ntawm Shanghai Qixuan Chemical Technology Co., Ltd. feem ntau raug nug ib lo lus nug tseem ceeb: yuav ua li cas xaiv tus lej EO kom raug?

TA05, uas yog tallow amine polyoxyethylene (5) ether, muab cov lus teb sawv cev rau lo lus nug no. Nws tsis nrhiav kev ua tau zoo heev ntawm ib qho cim qhia, tab sis pom nws txoj haujlwm txhim khu kev qha hauv ntau yam kev siv sib txawv.

TA05 yog tsim los ntawm ethoxylation ntawm cov tallow amine ntuj nrog 5 EO units, CAS No. 61791-26-2. Nws qhov hydrophobic ntu muaj cov sib xyaw ntev C16-C18 alkyl saw, thaum qhov hydrophilic ntu yog koom ua ke los ntawm tsib EO units thiab ib pawg protonatable amine.

Cov qauv tshwj xeeb no muab nws nrog ob lub luag haujlwm sib xws. Nyob rau hauv cov xwm txheej nruab nrab lossis alkaline, nws ua haujlwm ua ib qho surfactant nonionic, ua kom pom kev emulsification thiab dispersion ntawm hydration ntawm EO saw. Hauv cov chaw acidic, cov amine pawg tau protonated thiab nqa cov nqi zoo, qhia cov yam ntxwv cationic surfactant nrog cov adsorption affinity muaj zog rau cov substrates tsis zoo suav nrog cov hlau nto, cov zaub mov, fibers thiab asphalt particles. Lub tshuab ua haujlwm ob npaug no hauv ib lub molecule tso qhov laj thawj tseem ceeb vim li cas TA05 tau txais kev siv ntau zaus thoob plaws ntau yam lag luam.

Hais txog cov khoom siv lub cev, TA05 zoo li daj ntseg mus rau xim av viscous kua ntawm 25 ° C. Nws cov kua dej 1% yog alkaline nrog pH xws li 9 txog 11. Tus nqi amine tag nrho feem ntau tswj tau ntawm 110–120 mgKOH / g, noo noo ≤1.0%, Gardner xim ≤10, thiab tus nqi HLB yog kwv yees li 9. HLB no zaum ntawm ciam teb ntawm hydrophilicity thiab lipophilicity, ua rau nws yaj zoo hauv cov roj theem thaum tsiv mus rau cov roj-dej interfaces. Yog li ntawd nws yog qhov tsim nyog rau W / O emulsification, co-emulsification thiab interfacial wetting, es tsis yog ua haujlwm ua cov roj-hauv-dej emulsifier yooj yim.

Ib qho khoom noj tallow amine feedstock tuaj yeem ethoxylated rau hauv cov qib sib law liag nrog 2, 5, 10, 15 EO units, xa cov khoom sib txawv maj mam. Cov lej EO qis dua ua rau muaj lipophilicity ntau dua, cov nqi amine siab dua thiab cov dej tsis yaj zoo; cov ntsiab lus EO siab dua txhim kho cov dej solubility thiab hloov emulsifying nyiam mus rau O / W systems.

Qib 2 EO yog cov roj-soluble heev, yuav tsum tau dilute cov tshuaj yaj lossis cua sov kom dispersion hauv ntau cov formulations. Qib nrog 10 lossis ntau dua EO units qhia tau tias zoo dua dej solubility tab sis tsis muaj zog interfacial affinity hauv cov roj ntau, cov khoom muaj zog. Tsib EO units tawm tsam qhov nruab nrab sib npaug: nws khaws cov lipophilic segments txaus los anchor rau ntawm roj, asphalt thiab minerals surfaces, tib lub sijhawm muaj hydrophilic peev xwm yooj yim rau kev nthuav dav hauv aqueous media. Rau cov ntawv thov uas xav tau ob qho tib si emulsification thiab adsorption, sib npaug lipophilicity thiab dej dispersibility, qib no feem ntau ua tau zoo dua qib ntawm ob qho kawg ntawm EO spectrum.

Qhov ntawd kuj piav qhia vim li cas TA05 thiaj li raug suav hais tias yog "tus txuas tsim cov tshuaj". Nws cov dej yaj thiab cov huab tuaj yeem kho tau los ntawm kev sib xyaw nrog cov analogues EO siab dua, thaum kev ua haujlwm lipophilic tuaj yeem txhawb nqa los ntawm kev sib xyaw nrog cov variants EO qis. Hauv cov kab ke sib xyaw, nws ua haujlwm ua lub tsev thaiv kev hloov pauv yooj yim rau kev hloov kho cov tshuaj, feem ntau muaj txiaj ntsig zoo dua li cov khoom sib koom ua ke dua li tus neeg sawv cev tseem ceeb.

Dhau li ntawm cov haujlwm saum toj no, nws tuaj yeem siv ua cov tshuaj tiv thaiv thiab ua kom mos mos hauv kev ua cov ntaub los ntawm kev nqus mus rau ntawm cov nplaim fiber ntawm cov pab pawg protonated amine. Hauv cov khoom siv flotation, nws ua haujlwm ua tus neeg sau khoom pabcuam lossis cov khoom faib tawm uas vam khom kev coj ua cationic adsorption ntawm cov nplaim minerals.

Rau cov roj amine ethoxylates, kev ua tau raws li qhov yuav tsum tau ua tsuas yog qhov yuav tsum tau nkag mus xwb. Qhov uas tswj hwm qhov ruaj khov ntawm cov mis rau cov neeg siv khoom kawg yog kev faib tawm EO nqaim, tswj tau PEG dawb thiab cov ntsiab lus EO dawb, thiab xim ruaj khov thaum khaws cia. Kev faib tawm EO dav dav yuav ua rau muaj peev xwm emulsifying thiab dej solubility hloov pauv txawm tias muaj cov nqi amine zoo sib xws. Cov mis uas tau ua kom zoo tshaj plaws ntawm qhov ntsuas hauv chav kuaj feem ntau ua tsis tiav thaum lub sijhawm sim lossis tag nrho cov khoom tsim tawm.

Ntawm Qixuan, cov cim qhia tseem ceeb rau TA05 npog cov nqi amine, dej noo, pH thiab xim, nrog rau kev sim ua ke tag nrho thiab khaws cov qauv kom taug qab tau. Cov ntim txheem yog 180 kg ib lub nruas, thaum IBC tote thiab cov ntim OEM customized muaj thaum thov.

• [1] Txhais lub qhov rais pH ua ntej kev ntsuam xyuas kev sib raug zoo:TA05 ua haujlwm zoo li cationic nyob rau hauv cov xwm txheej acidic thiab nonionic nyob rau hauv cov xwm txheej alkaline. Nws cov neeg koom tes sib xws, kev noj zaub mov thiab cov koob tshuaj pom zoo sib txawv ntawm ob qho chaw no.
• [2] Tsis txhob sib tov nrog cov tshuaj anionic surfactants ntau dhau:Thaum sib xyaw nrog cov hom anionic, cov tshuaj surfactants nruab nrab lossis cov kab ke pub mis sib cais raug pom zoo kom tiv thaiv kev sib xyaw ua ke hauv zos thiab cov dej nag.
• [3] Tswj qhov kub thiab txias ntawm kev pub mis:TA05 muaj viscosity siab, tshwj xeeb tshaj yog nyob rau hauv qhov kub qis thaum lub caij ntuj no. Kev ua kom sov txog li 60 ° C ua ntej kev ntsuas tshuaj pab txhawb kev ntsuas kom raug thiab tiv thaiv kev sib xyaw ua ke hauv zos.

Kev xaiv cov tshuaj surfactant yog qhov tseem ceeb nrhiav qhov chaw zoo tshaj plaws raws li cov kab EO tuning txuas ntxiv. Qhov zoo ntawm TA05 tsis yog nyob rau hauv kev ua tau zoo tshaj plaws ntawm ib qho khoom, tab sis nyob hauv thaj chaw nruab nrab uas feem ntau tsis quav ntsej txog kev sib npaug ntawm lipophilicity thiab hydrophilicity nrog ntau yam kev xav tau ntawm kev ua lag luam.

Shanghai Qixuan Chemical Technology Co., Ltd. muab cov khoom siv tallow amine polyoxyethylene ether tiav. Peb npaj txhij los muab cov EO variants thiab kev txhawb nqa kev siv tshuab uas phim koj cov kev xav tau tshwj xeeb.
