Pfungwa dzakakosha uye kuiswa kwe cellulose ether

Cellulose Ether kirasi yekirasi yePolytile yePolymers inotorwa kubva kuCellulose, chisikwa chinoitika polysaccharide inowanikwa mumasango masero emadziro. Cellulose ana vana vanoshandiswa zvakanyanya mumagirendi akasiyana siyana nekuda kwezvivakwa zvavo zvakasarudzika, izvo zvinosanganisira kurwadzisa, kudzora kwemvura, kugadzira firimu, uye kusimbisa kugona. Heino pfungwa dzakakosha uye matsotsi e cellulose eter:

Pfungwa dzakakosha:

1. Cellulose chimiro:
   • Cellulose inoumbwa nekudzokorora maGlucose zvikamu zvakabatana pamwechete ne β (1 → 4) Glycosiic Zvisungo. Iyo inogadzira marefu, mutsara maketeni anopa rutsigiro rwemhando kumasima masero.
2. Etera:
   • Cellulose etana inogadzirwa kuburikidza nemakemikari kugadziridzwa kwemheremalose nekuunza mapoka (-Och2Cch2oh, etc.) kuHydroxyl (-Ooh) mapoka emherulose Molecule.
3. Kushanda:
   • Nhungamiro yemapoka e-ether inoshandura zvivakwa zvemakemikari uye zvemuviri zve cellerse, uchipa cellulose eterlose mashandiro ezvakasarudzika senge solubility, viscosity, kudzokorora kwemvura, uye kuumbwa kwemvura.
4. Biodegradability:
   • Cellulose ana ana ana bioderable polymers, zvichireva kuti ivo vanogona kuputswa nehutachiona munharaunda, zvichitungamira kuumbwa kwezvinhu zvisina kukuvadza ne-zvigadzirwa.

Kugadziriswa:

Cellulose ana anaiters yakavhenganiswa kubva kune mhando yemazita emamwe mapoka akaunzwa kune iyo cellulose Molecule uye yavo degree rekutsiva. Mhando dzakajairika dze cellulose aungana unosanganisira:

1. MetHyl Cellulose (MC):
   • MetHyll Cellulose inogadzirwa nekuunza methyl (-Och3) mapoka kune iyo cellulose Molecule.
   • Izvo zvinonyangadza mumvura inotonhora uye inoumba pachena, viscous mhinduro. MC inoshandiswa seanoti, stabilizer, uye firimu raimbova mune dzakasiyana siyana application.
2. HydroxytHyl Cellulose (Hec):
   • HydroxytHyl Cellulose inowanikwa nekuunza hydroxylyl (-Och2ch2oh) mapoka kune iyo cellulose Molecule.
   • Izvo zvinoratidzira kuchengetedza kwakanakisa uye kuremadza kwemvura, zvichiita kuti zviite kuti zvisike mukupenda, zvinonamatira, zvizarisi, uye mishonga, uye mishonga.
3. Hydroxyprupyl methyl cellulose (HPMC):
   • HydroxyPropyl methyl cellel cellulose is a copolymer ye methyl cellulose uye hydroxypruppropyl cellulose.
   • Iyo inopa chiyero chezvinhu zvakadai sekusarudzika kwemvura, kudzora kwe viscosity, uye kuumbwa kwemafirimu. HPMC inoshandiswa zvakanyanya mukuvaka, mishonga yemishonga, uye zvigadzirwa zvega zvega.
4. Carboxymethyl Cellulose (cmc):
   • CarboxyMethyl Cellelose inogadzirwa nekuunza CarboxyMethyl (-Och2cooh) mapoka kune iyo cellulose Molecule.
   • Izvo zvinonyangadza mumvura uye zvinoumba viscous mhinduro neakanakisa kurongedza uye kusimbisa zvivakwa. CMC inoshandiswa muchikafu, mishonga yemishonga, uye maindasitiri ekushandisa.
5. Ethyl hydroxyll cellulose (ehec):
   • Ethyl Hydroxyll Cellalose anowanikwa nekuunza ethyl uye hydroxytHilsl mapoka kune iyo cellulose Molecule.
   • Izvo zvinoratidzira kuchengetedza kwemvura, kuremerwa, uye zvimiro zvetsiva zvichienzaniswa nehec. Ehec inoshandiswa mune zvekuvaka zvinhu uye zvigadzirwa zvega zvega.

Cellulose ana vana yakakosha polymers ine dzakasiyana-siyana maindasitiri akasiyana maindasitiri akasiyana. Kugadziridzwa kwavo kwemakemikari kuburikidza nekuwedzera kunopa kune dzakasiyana siyana masangano, kuita kuti ivo vanowedzera vanowedzera mukuumbwa kwemapepa, vanoshambidza, zvizarisi, zvigadzirwa, zvigadzirwa zvekudya, uye zvigadzirwa zvekuvaka, uye zvigadzirwa zvekuvaka, uye zvigadzirwa zvekuvaka, uye zvigadzirwa zvekuvaka, uye zvigadzirwa zvekuvaka. Kunzwisisa pfungwa dzakakosha uye zvikamu zve cellulose anainers zvakakosha kusarudza mhando yakakodzera ye polymer yezvakangoita zvekushandisa.
