Tus lej lej 9004-62-0 yog cov tshuaj lom neeg tus lej ntawm hydroxyethyl cellulose (HEC). Hydroxyethyl cellulose yog cov dej tsis-ionic-soluble polymer nquag siv nyob rau hauv ntau cov tuab si thiab cov khoom siv ua yeeb yam, zaj duab xis-forming thiab hydration khoom. Nws muaj ntau cov kev siv, npog cov tsho tiv no, kev tsim kho, khoom noj, tshuaj, tshuaj pleev ib ce thiab lwm thaj teb.
1. Cov khoom yooj yim ntawm hydroxyethyl cellulose
Molecular tus qauv: Ua raws li nws qib ntawm polymerization, nws yog lub cellulose derivative;
Tus lej lej: 9004-62-0;
Zog: hydroxyethyl cellulose feem ntau pom nyob rau hauv daim ntawv ntawm dawb los yog lub teeb daj hmoov, nrog ntxhiab tsw thiab cov yam ntxwv tsw qab;
Solubility: HEC tuaj yeem yaj nyob rau hauv ob qho tib si txias thiab dej kub, muaj solubility zoo thiab ruaj khov, thiab cov tshuaj pob tshab lossis cov tshuaj txhais tau tom qab xaus.
Kev npaj ntawm hydroxyethyl cellulose
Hydroxyethyl cellulose tau npaj los ntawm kev siv cellulose cellulose nrog ethylene oxide. Hauv cov txheej txheem no, ethylene oxide reacts nrog hydroxyl pawg ntawm cellulose los ntawm kev tiv thaiv kab mob herebyethylated cellulose. Los ntawm kho cov tshuaj tiv thaiv kab mob, cov qib ntawm hydroxyethern hloov tuaj yeem tswj cov khoom siv solubility, yog li kho cov dej solubility, yog li hloov kho lub cev ntawm HEC.
2. Lub cev thiab tshuaj lom neeg ntawm hydroxyethyl cellulose
Viscosity/8 Hydroxyethyl cellulose yog qhov ua kom zoo siv ua kom zoo thiab yog dav siv los kho cov viscosity ntawm cov kua. Nws cov kev daws viscosity nyob ntawm cov solubility confrtration, qib ntawm cov khoom siv, yog li nws cov khoom siv hluav taws xob, yog li nws cov phaus molecular;
Cov haujlwm saum npoo av: Txij li HEC lwg me me muaj ntau pawg ntawm cov pab pawg molroxyl, lawv tuaj yeem ua lub luag haujlwm ntawm surfactant, thiab pab ua si emulsions thiab kev ncua;
Zaj duab xis ua yeeb yaj kiab: Hydroxyethyl cellulose tuaj yeem tsim cov yeeb yaj kiab tsis zoo tom qab ziab, yog li nws tau siv dav hauv cov tshuaj pleev ib ce, tshuaj pleev ib ce thiab lwm daim teb;
Cov dej noo khaws cia: hydroxyethyl cellulose muaj cov dej num zoo, tuaj yeem nqus thiab khaws cov dej noo, thiab pab txuas ntxiv cov khoom noo ntawm cov khoom lag luam.
3. Cov chaw thov
Txheej txheem thiab cov ntaub ntawv hauv tsev: HEC yog cov tuab tuab siv tuab thiab siv khov kho hauv kev lag luam txheej. Nws tuaj yeem txhim kho cov rhheology ntawm txheej, ua rau txheej ntau yam zoo nkauj, thiab zam dhau siagging. Hauv cov ntaub ntawv hauv tsev, nws yog siv nyob rau hauv xis mas cug, gypsum, putty hmoov, thiab lwm yam.
Tshuaj txhua hnub: hauv cov tshuaj pleev ib ce thiab cov khoom siv saib xyuas tus kheej, tshuaj pleev qhov quav, tshuaj tiv thaiv thiab tshem tawm cov nyhuv siv.
Kev lag luam khoom noj khoom haus: txawm hais tias HEC tsis tshua siv nyob rau hauv cov zaub mov, nws tuaj yeem siv los ua cov ntaub tuab thiab cov zaub mov tshwj xeeb xws li cov mis nyuj thiab cov khoom nyiam.
Kev teb Medical
Kev Lag Luam Kev Lag Luam: HEC yog siv los ua cov ntawv txhim kho, nto Smoothener thiab txheej Additive hauv kev lag luam papermaking.
4. Qhov zoo ntawm hydroxyethyl cellulose
Zoo solubility: HEC yog yooj yim soluble hauv dej thiab tuaj yeem tsim cov tshuaj uas tsis muaj hom phiaj.
Kev thov kev hloov siab thoob plaws: HEC yog tsim nyog rau ntau yam qauv xov xwm thiab pH.
Cov tshuaj zoo: HEC yog qhov ruaj ntseg nyob rau hauv ntau hom kuab tshuaj thiab huab cua sov thiab tuaj yeem tswj hwm nws cov haujlwm ntev.
5. Kev noj qab haus huv thiab kev nyab xeeb ntawm hydroxyethyl cellulose
Hydroxyethyl cellulose feem ntau suav hais tias yog ib yam khoom uas tsis muaj teeb meem rau tib neeg lub cev. Nws tsis yog tshuaj lom thiab tsis ua rau cov tawv nqaij lossis qhov muag, yog li nws tau siv dav hauv cov tshuaj pleev ib ce thiab tshuaj. Nyob rau hauv ib puag ncig, HEC tseem muaj zoo biodegradity thiab tsis ua rau ib puag ncig pa phem.
Hydroxyethyl cellulose sawv cev los ntawm CAS No. 9004-62-0 yog cov khoom siv polymer ntau zog polymer nrog kev ua tau zoo heev. Vim nws cov thickening, ua yeeb yaj kiab, zaj duab xis-sib sau, moisturizing thiab lwm yam khoom, nws yog dav siv nyob rau hauv ntau yam ntawm kev lag luam kev tsim khoom thiab lub neej txhua hnub.
