Cellulose ethers iboka remapolymers anosiyana-siyana uye anoshandiswa zvakanyanya akatorwa kubva ku cellulose, yakasikwa polysaccharide inowanikwa muchirimwa sero madziro.Aya mapolymer anoratidzirwa nekunyungudika kwemvura, biodegradability, uye firimu-kugadzira zvimiro.Kunyangwe cellulose ether isingashandiswe zvakananga mukugadzira mapurasitiki echinyakare, anoita basa rakakosha mumaindasitiri akasiyana akadai semishonga, chikafu, kuvaka uye machira.
Cellulose Ethers: Overview
Cellulose ndiyo yakanyanya kuwanda organic polymer Panyika, uye zvinobva pairi, zvinonzi cellulose ethers, zvinogadzirwa kuburikidza nekugadziriswa kwekemikari yemamorekuru e cellulose.Zvinowanzowanikwa zve cellulose zvinosanganisira huni pulp, donje, uye mamwe mashizha emiti.
Iwo makuru cellulose ether anosanganisira:
Methylcellulose (MC): Yakagadzirwa nekutsiva mapoka ehydroxyl e cellulose nemapoka emethyl, MC inoshandiswa zvakanyanya muindasitiri yechikafu, mishonga uye kuvaka.Iyo inozivikanwa nokuda kwekuchengetedza mvura, zvichiita kuti ive yakanakira kuwedzera mune zvakasiyana-siyana zvekushandisa.
Hydroxypropylcellulose (HPC): Muchikamu ichi, mapoka ehydroxyl e cellulose anotsiviwa nemapoka ehydroxypropyl.HPC inowanzoshandiswa mumishonga, zvizorwa, uye zvigadzirwa zvekuchengeta munhu nekuda kwekugadzira firimu uye kukora zvivakwa.
Hydroxyethyl cellulose (HEC): HEC inowanikwa nekuunza mapoka ehydroxyethyl mu cellulose.Inoshandiswa seyakakora, binder uye stabilizer mumaindasitiri akadai seanonamira, pendi uye zvigadzirwa zvekuchengeta munhu.
Carboxymethylcellulose (CMC): CMC inowanikwa nekutsiva chikamu chemapoka ehydroxyl nemapoka ecarboxymethyl.Inoshandiswa zvakanyanya muindasitiri yechikafu seyakakora uye inodzikamisa uye muindasitiri yemishonga kune yayo inonamira zvinhu.
Kushandiswa kwe cellulose ethers
1. Indasitiri yezvekudya:
Cellulose ethers, kunyanya CMC, inoshandiswa zvakanyanya muindasitiri yechikafu kusimudzira magadzirirwo, kugadzikana uye viscosity yezvakasiyana zvigadzirwa zvakaita seaizikirimu, saradhi yekupfeka uye zvinhu zvakabikwa.
2. Zvinodhaka:
Methylcellulose uye mamwe ma cellulose ethers anoshandiswa mukugadzirwa kwemishonga semabinders, disintegrants, uye firimu-forming agents mukugadzira mapiritsi.
3. Indasitiri yekuvaka:
HEC uye MC inowanzoshandiswa muindasitiri yekuvaka kuvandudza mashandiro ematokari, anonamira uye machira.Vanobatsira kuvandudza kushanda uye kuchengetedza mvura.
4. Zvigadzirwa zvekuchengeta wega:
Hydroxypropyl cellulose uye hydroxyethyl cellulose inowanikwa mune zvakasiyana siyana zvekuchengetedza munhu zvakadai seshamposi, lotions uye zvizorwa, zvinopa viscosity uye kugadzikana.
5. Micheka:
Cellulose ethers inoshandiswa mukudhinda machira uye kudhaya maitiro nekuda kwekukora uye kudzikamisa zvivakwa.
Cellulose ethers ine akawanda mabhenefiti ezvakatipoteredza:
Biodegradability:
Kusiyana nemapolymer mazhinji ekugadzira, cellulose ethers inogona kuparara, zvichireva kuti inoputsika kuburikidza nemaitiro echisikigo, ichideredza kukanganisa kwayo nharaunda.
Renewable Energy:
Cellulose, iyo mbishi ye cellulose ethers, inotorwa kubva kune inogona kudzokororwa zviwanikwa zvakaita sehuni nekudyara fiber.
Deredza kutsamira pane petrochemicals:
Kushandiswa kwe cellulose ethers mune zvakasiyana-siyana zvekushandisa kunoderedza kuvimba ne petrochemical polymers uye inobatsira kune imwe nzira yakagadzikana.
Matambudziko negwara remangwana
Nepo cellulose ethers ichipa akawanda mabhenefiti, kune zvakare mamwe matambudziko, akadai seashoma kugadzikana kwemafuta uye shanduko dzinogona kuitika muzvivakwa zvinoenderana nekwakabva cellulose.Tsvagiridzo inoenderera mberi yakanangana nekugadzirisa matambudziko aya uye kuongorora mashandisirwo matsva e-cellulose ethers munzvimbo dziri kusimukira.
Cellulose ethers inotorwa kubva kune yakawanda inovandudzwa cellulose uye inoita basa rakakosha mumaindasitiri akasiyana.Kunyangwe iwo asiri echinyakare mapurasitiki, zvimiro zvavo zvinobatsira mukuvandudza kwezvakatipoteredza zvigadzirwa uye maitiro.Sezvo maindasitiri ari kuramba achitsvaga dzimwe nzira dzakasimba, cellulose ethers inogona kuramba iri pamberi pekuvandudza, ichifambisa kufambira mberi mumhando dzakasiyana dzekushandisa.
