Nomoro ea CAS 9004-62-0 ke nomoro ea boitsebiso ba lik'hemik'hale ea Hydroxyethyl Cellulose (HEC). Hydroxyethyl Cellulose ke polymer e se nang ionic e qhibilihang ka metsing e atisang ho sebelisoa lihlahisoa tse fapa-fapaneng tsa indasteri le tsa letsatsi le letsatsi tse nang le thepa e teteaneng, e tsitsitseng, ea ho etsa lifilimi le ea hydration. E na le mefuta e mengata ea lits'ebetso, ho koahela liaparo, kaho, lijo, meriana, litlolo le masimo a mang.
1. Lintho tsa motheo tsa Hydroxyethyl Cellulose
Foromo ea molek'hule: Ho itšetlehile ka tekanyo ea eona ea polymerization, ke motsoako oa cellulose;
Nomoro ea CAS: 9004-62-0;
Ponahalo: Hydroxyethyl Cellulose hangata e hlaha ka sebōpeho sa phofo e tšoeu kapa e bobebe e mosehla, e nang le litšobotsi tse se nang monko le tse sa latsoeheng;
Solubility: HEC e ka qhibiliha ka metsing a batang le a chesang, e na le ho qhibiliha hantle le ho tsitsa, 'me e etsa tharollo e hlakileng kapa ea translucent ka mor'a ho qhibiliha.
Tokisetso ea Hydroxyethyl Cellulose
Hydroxyethyl Cellulose e hlophisitsoe ka selulose e sebetsanang le lik'hemik'hale ka ethylene oxide. Ts'ebetsong ena, ethylene oxide e sebetsana le sehlopha sa hydroxyl sa cellulose ka karabelo ea etherification ho fumana cellulose ea hydroxyethylated. Ka ho fetola maemo a karabelo, tekanyo ea hydroxyethyl substitution e ka laoloa, ka hona ho fetola ho qhibiliha ha metsi, viscosity le lintho tse ling tsa 'mele tsa HEC.
2. Lintho tsa 'mele le tsa lik'hemik'hale tsa hydroxyethyl cellulose
Taolo ea Viscosity: Hydroxyethyl cellulose ke setenya se sebetsang hantle 'me se sebelisoa haholo ho lokisa viscosity ea lino. Tharollo ea eona ea viscosity e itšetlehile ka mahloriso a solubility, tekanyo ea polymerization le tekanyo ea ho fetola, kahoo thepa ea eona ea rheological e ka laoloa ka ho fetola boima ba molek'hule;
Mosebetsi o ka holimo: Kaha limolek'hule tsa HEC li na le lihlopha tse ngata tsa hydroxyl, li ka etsa filimi ea molek'hule holim'a sebopeho, li bapala karolo ea surfactant, 'me li thusa ho tsitsisa li-emulsions le mekhoa ea ho emisa;
Thepa ea ho etsa lifilimi: Hydroxyethyl cellulose e ka etsa filimi e ts'oanang ka mor'a ho omisoa, kahoo e sebelisoa haholo litlolo, litlolo tsa meriana le masimo a mang;
Ho boloka mongobo: Hydroxyethyl cellulose e na le hydration e ntle, e ka monya le ho boloka mongobo, 'me e thusa ho lelefatsa nako ea ho nosetsa sehlahisoa.
3. Libaka tsa kopo
Liaparo le thepa ea mohaho: HEC ke "thickener" e atisang ho sebelisoa le stabilizer indastering ea ho roala. E ka ntlafatsa rheology ea ho roala, ea etsa hore seaparo se tšoane hantle, 'me se qobe ho senya. Ka thepa ea kaho, e sebelisoa ka seretse sa samente, gypsum, putty powder, joalo-joalo, ho ntlafatsa ts'ebetso ea kaho, ho matlafatsa ho boloka metsi le ho ntlafatsa ho hanyetsa ha crack.
Lik'hemik'hale tsa letsatsi le letsatsi: Ka litlolo le lihlahisoa tsa tlhokomelo ea botho, HEC e atisa ho sebelisoa ka shampoo, gel ea ho hlatsoa, lotion le lihlahisoa tse ling ho fana ka ho tsitsisa le ho emisa, ha ho ntse ho matlafatsa phello ea mongobo.
Indasteri ea lijo: Le hoja HEC e sa sebelisoe hangata lijong, e ka sebelisoa e le setepi le se matlafatsang lijong tse itseng tse kang ice cream le li-condiments.
Lekala la bongaka: HEC e sebelisoa haholo-holo e le motenya le matrix bakeng sa li-capsules litokisetsong tsa meriana, haholo-holo meriana ea mahlo bakeng sa ho etsa meokho ea maiketsetso.
Indasteri ea ho etsa lipampiri: HEC e sebelisoa e le sehlahisoa sa pampiri, boreleli ba bokaholimo le tlatsetso ea ho roala indastering ea ho etsa pampiri.
4. Melemo ea hydroxyethyl cellulose
Sollubility e ntle: HEC e qhibiliha habonolo ka metsing 'me e ka etsa tharollo ea viscous kapele.
Ho ikamahanya le maemo a pharaletseng a kopo: HEC e loketse mefuta e fapaneng ea mecha ea litaba le pH.
Botsitso bo botle ba lik'hemik'hale: HEC e batla e tsitsitse mefuteng e fapaneng ea li-solvents le mocheso 'me e ka boloka mesebetsi ea eona ka nako e telele.
5. Bophelo bo botle le polokeho ea hydroxyethyl cellulose
Hydroxyethyl cellulose hangata e nkuoa e le ntho e se nang kotsi 'meleng oa motho. Ha e chefo ebile ha e halefise letlalo kapa mahlo, kahoo e sebelisoa haholo litlolong le meriana. Tikolohong, HEC e boetse e na le biodegradability e ntle mme ha e bake tšilafalo ea tikoloho.
Hydroxyethyl cellulose e emetsoeng ke CAS No. 9004-62-0 ke lisebelisoa tse ngata tsa polymer tse nang le ts'ebetso e babatsehang. Ka lebaka la ho teteka ha eona, ho tsitsisa, ho etsa lifilimi, ho nosetsa le lintho tse ling, e sebelisoa haholo likarolong tse sa tšoaneng tsa tlhahiso ea indasteri le bophelo ba letsatsi le letsatsi.
