Ndeapi marudzi eCellulose ether?

Cellulose ethers iboka rakasiyana siyana remapolymers anobva ku cellulose, yakasikwa polysaccharide inowanikwa muzvirimwa. Iwo anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira ekuvaka, emishonga, chikafu, zvizorwa, uye kutarisirwa kwevanhu, nekuda kwezvivakwa zvavo zvakasiyana uye kuita zvakasiyana. Heano mamwe emhando dzakajairika dze cellulose ether:

1. Methyl Cellulose (MC):
   • Methyl cellulose inogadzirwa nekurapa cellulose nemethyl chloride kuunza methyl mapoka kumusana we cellulose.
   • Iyo inonyungudika mumvura inotonhora uye inoumba yakajeka, viscous mhinduro.
   • MC inoshandiswa seyakakora, bhainda, uye inodzikamisa mune dzakasiyana siyana dzekushandisa, zvinosanganisira zvekuvakisa (semuenzaniso, simende-based mortars, gypsum-based plasters), zvigadzirwa zvekudya, mishonga, uye zvinhu zvekuchengeta munhu.
2. Hydroxyethyl Cellulose (HEC):
   • Hydroxyethyl cellulose inogadzirwa nekuita cellulose ine ethylene oxide kuunza hydroxyethyl mapoka kumusana we cellulose.
   • Inonyungudika mumvura inotonhora uye inoumba yakajeka, viscous mhinduro ine yakanakisa yekuchengetedza mvura zvivakwa.
   • HEC inowanzoshandiswa seyakakora, rheology modifier, uye firimu-forming agent mupendi, zvinonamira, zvigadzirwa zvekuchengeta munhu, uye mishonga yemishonga.
3. Hydroxypropyl Methyl Cellulose (HPMC):
   • Hydroxypropyl methyl cellulose inogadzirwa nekuunza hydroxypropyl uye methyl mapoka pane cellulose musana.
   • Inoratidza zvivakwa zvakafanana nezvose methyl cellulose uye hydroxyethyl cellulose, kusanganisira kunyungudika kwemvura, kugona kugadzira firimu, uye kuchengetedza mvura.
   • HPMC inoshandiswa zvakanyanya mukuvaka zvinhu (semuenzaniso, zvinonamira mataira, simende-based renders, self-leveling compounds), pamwe nemishonga, zvigadzirwa zvekudya, uye zvinhu zvekuchengeta munhu.
4. Carboxymethyl Cellulose (CMC):
   • Carboxymethyl cellulose inotorwa kubva ku cellulose nekuibata ne sodium hydroxide uye monochloroacetic acid kuunza carboxymethyl mapoka.
   • Iyo inonyungudika mumvura uye inoumba yakajeka, viscous mhinduro ine yakanakisa kukora, kudzikamisa, uye kuchengetedza mvura zvivakwa.
   • CMC inowanzoshandiswa seyakakora, binder, uye rheology modifier muzvigadzirwa zvekudya, mishonga, machira, mapepa, uye zvimwe zvekuvaka.
5. Ethyl Cellulose (EC):
   • Ethyl cellulose inogadzirwa nekuita selulosi ne ethyl chloride kuunza mapoka ethyl pamusana we cellulose.
   • Hainyungudike mumvura asi inonyungudika muorganic solvents senge ethanol nechloroform.
   • EC inowanzoshandiswa semumiriri wekugadzira firimu, binder, uye coating zvinhu mumishonga, zvigadzirwa zvekudya, zvekuzora, uye maindasitiri ekushandisa.

Aya ndiwo mamwe emhando dzinowanzo shandiswa dze cellulose ether, imwe neimwe inopa yakasarudzika zvivakwa uye mabhenefiti kune akasiyana maapplication. Mamwe hunyanzvi cellulose ethers anogonawo kuvepo, akagadzirirwa kune chaiwo zvinodiwa mumaindasitiri akasiyana.
