CAS Naj Npawb 9004-62-0 yog tus lej cim tshuaj ntawm Hydroxyethyl Cellulose (HEC). Hydroxyethyl Cellulose yog non-ionic dej-soluble polymer feem ntau siv nyob rau hauv ntau yam kev lag luam thiab niaj hnub khoom nrog thickening, stabilization, film-forming thiab hydration zog. Nws muaj ntau yam kev siv, npog txheej, kev tsim kho, khoom noj khoom haus, tshuaj, tshuaj pleev ib ce thiab lwm yam.
1. Cov khoom tseem ceeb ntawm Hydroxyethyl Cellulose
Molecular mis: Nyob ntawm nws qib ntawm polymerization, nws yog cellulose derivative;
CAS Nr .: 9004-62-0;
Cov tsos mob: Hydroxyethyl Cellulose feem ntau tshwm nyob rau hauv daim ntawv ntawm cov hmoov dawb los yog lub teeb daj, muaj ntxhiab tsw thiab saj tsis zoo;
Solubility: HEC tuaj yeem yaj hauv ob qho dej txias thiab kub, muaj kev solubility zoo thiab ruaj khov, thiab tsim cov pob tshab los yog cov kua nplaum tom qab tawg.
Kev npaj ntawm Hydroxyethyl Cellulose
Hydroxyethyl Cellulose yog npaj los ntawm chemically reacting cellulose nrog ethylene oxide. Hauv cov txheej txheem no, ethylene oxide reacts nrog pawg hydroxyl ntawm cellulose los ntawm cov tshuaj tiv thaiv etherification kom tau hydroxyethylated cellulose. Los ntawm kev kho cov tshuaj tiv thaiv, qhov degree ntawm hydroxyethyl hloov pauv tuaj yeem tswj tau, yog li kho cov dej solubility, viscosity thiab lwm yam khoom siv lub cev ntawm HEC.
2. Lub cev thiab tshuaj muaj zog ntawm hydroxyethyl cellulose
Kev tswj hwm viscosity: Hydroxyethyl cellulose yog cov thickener zoo thiab yog dav siv los kho cov viscosity ntawm cov kua. Nws cov tshuaj viscosity nyob ntawm qhov solubility concentration, degree ntawm polymerization thiab degree ntawm kev hloov, yog li nws cov khoom rheological tuaj yeem tswj tau los ntawm kev kho qhov hnyav molecular;
Kev ua haujlwm saum npoo: Txij li HEC molecules muaj ntau pawg hydroxyl, lawv tuaj yeem tsim cov yeeb yaj kiab molecular ntawm qhov sib cuam tshuam, ua lub luag haujlwm ntawm surfactant, thiab pab tswj cov emulsion thiab ncua kev kawm;
Cov cuab yeej ua yeeb yaj kiab: Hydroxyethyl cellulose tuaj yeem tsim cov yeeb yaj kiab zoo tom qab ziab, yog li nws tau siv dav hauv cov tshuaj pleev ib ce, tshuaj pleev xim thiab lwm yam;
Kev tuav dej noo: Hydroxyethyl cellulose muaj dej zoo, tuaj yeem nqus tau thiab khaws cov dej noo, thiab pab txuas ntxiv lub sijhawm moisturizing ntawm cov khoom.
3. Cov chaw thov
Txheej thiab cov khoom siv hauv tsev: HEC yog ib qho uas nquag siv cov thickener thiab stabilizer hauv kev lag luam txheej. Nws tuaj yeem txhim kho rheology ntawm txheej txheej, ua kom cov txheej txheej zoo sib xws, thiab tsis txhob sagging. Hauv cov khoom siv hauv tsev, nws yog siv rau hauv cov cement mortar, gypsum, putty hmoov, thiab lwm yam., txhawm rau txhim kho kev tsim kho, txhim kho dej tuav thiab txhim kho kev tawg.
Cov tshuaj niaj hnub: Hauv cov tshuaj pleev ib ce thiab cov khoom siv tu tus kheej, HEC feem ntau siv tshuaj zawv plaub hau, gel da dej, tshuaj pleev thiab lwm yam khoom los muab cov thickening thiab suspension stabilization, thaum txhim kho cov nyhuv moisturizing.
Kev lag luam khoom noj khoom haus: Txawm hais tias HEC tsis tshua siv rau hauv cov zaub mov, nws tuaj yeem siv los ua cov thickener thiab stabilizer hauv qee yam khoom noj xws li ice cream thiab condiments.
Kev kho mob: HEC feem ntau yog siv los ua cov thickener thiab matrix rau cov tshuaj ntsiav hauv kev npaj tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj ophthalmic rau kev tsim cov kua muag dag.
Papermaking kev lag luam: HEC yog siv los ua daim ntawv txhim kho, nto smoothener thiab txheej additive hauv kev lag luam papermaking.
4. Qhov zoo ntawm hydroxyethyl cellulose
Solubility zoo: HEC yooj yim soluble hauv dej thiab tuaj yeem tsim cov kua nplaum sai.
Kev siv dav dav: HEC haum rau ntau yam kev tshaj tawm thiab pH ib puag ncig.
Kev ruaj ntseg tshuaj zoo: HEC yog qhov ruaj khov nyob rau hauv ntau yam ntawm cov kuab tshuaj thiab qhov kub thiab txias thiab tuaj yeem tswj tau nws txoj 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 muaj tshuaj lom thiab tsis ua rau tawv nqaij lossis qhov muag, yog li nws tau siv dav hauv tshuaj pleev ib ce thiab tshuaj. Hauv ib puag ncig, HEC kuj muaj biodegradability zoo thiab tsis ua rau muaj kuab paug ib puag ncig.
Hydroxyethyl cellulose sawv cev los ntawm CAS No. Vim nws thickening, stabilization, film-forming, moisturizing thiab lwm yam khoom, nws yog dav siv nyob rau hauv ntau yam ntawm industrial ntau lawm thiab lub neej txhua hnub.
