Gutezimbere no Gukoresha Cellulose Ether

Gutezimbere no Gukoresha Cellulose Ether

Ether ya selile yateye imbere cyane kandi ibona ibikorwa byinshi mubikorwa bitandukanye kubera imiterere yihariye na kamere zitandukanye. Dore incamake yiterambere nogukoresha kwa selile ethers:

  1. Iterambere ryamateka: Iterambere rya ethers ya selile ryatangiye mu mpera z'ikinyejana cya 19, hamwe no kuvumbura inzira zo guhindura imiti ya molekile ya selile. Imbaraga za mbere zibanze ku buhanga bwa derivatisation bwo kumenyekanisha amatsinda ya hydroxyalkyl, nka hydroxypropyl na hydroxyethyl, ku mugongo wa selile.
  2. Guhindura imiti: Ethers ya selile ikoreshwa muguhindura imiti ya selile, cyane cyane na etherification cyangwa esterification reaction. Etherification ikubiyemo gusimbuza hydroxyl matsinda ya selile hamwe na ether matsinda, mugihe esterification ibasimbuza amatsinda ya ester. Ihinduka ritanga ibintu bitandukanye kuri selile ya selile, nko gukomera mumazi cyangwa ibishishwa kama, ubushobozi bwo gukora firime, no kugenzura ibishishwa.
  3. Ubwoko bwa Ethers ya Cellulose: Ethers isanzwe ya selile irimo methyl selulose (MC), hydroxypropyl selulose (HPC), hydroxyethyl selulose (HEC), carboxymethyl selulose (CMC), na hydroxypropyl methyl selulose (HPMC). Buri bwoko bufite imiterere yihariye kandi burakwiriye kubisabwa byihariye.
  4. Gusaba mubwubatsi: Ether ya selile ikoreshwa cyane mubikorwa byubwubatsi nkinyongera mubikoresho bya sima, nka minisiteri, grout, nibicuruzwa bishingiye kuri gypsumu. Batezimbere imikorere, kubika amazi, gufatira hamwe, hamwe nibikorwa rusange byibi bikoresho. HPMC, byumwihariko, ikoreshwa cyane mumatafari ya tile, gushushanya, hamwe no kwishyira hamwe.
  5. Porogaramu muri Pharmaceuticals: Ethers ya selile igira uruhare runini mugutegura imiti nka binders, disintegrants, abakora firime, nabahindura viscosity. Bikunze gukoreshwa mububiko bwa tablet, kugenzura-kurekura, guhagarika, hamwe nibisubizo byamaso bitewe na biocompatibilité, ituze, hamwe numwirondoro wumutekano.
  6. Gushyira mu bikorwa ibiryo no kwita ku muntu ku giti cye: Mu nganda z’ibiribwa, ether ya selile ikoreshwa nkibibyimbye, stabilisateur, na emulisiferi mu bicuruzwa byinshi, birimo isosi, imyambarire, ibikomoka ku mata, n’ibicuruzwa bitetse. Mu bicuruzwa byita ku muntu ku giti cye, biboneka mu menyo yinyo, shampoo, amavuta yo kwisiga, hamwe no kwisiga kugirango bibyibushye kandi bitose.
  7. Ibitekerezo ku bidukikije: Ethers ya selile ifatwa nkibikoresho bitekanye kandi bitangiza ibidukikije. Nibishobora kwangirika, gusubirwamo, no kutagira uburozi, bigatuma bakora ubundi buryo bushimishije kuri polymrike ya synthique mubikorwa byinshi.
  8. Ubushakashatsi bukomeje no guhanga udushya: Ubushakashatsi muri selile ya selile ikomeje gutera imbere, hibandwa ku guteza imbere ibikomoka ku bitabo bishya bifite imiterere yiyongereye, nko kumva ubushyuhe, kubyutsa imbaraga, hamwe na bioactivite. Byongeye kandi, imbaraga zirimo gukorwa kugirango tunonosore umusaruro, tunoze irambye, kandi dushakishe porogaramu nshya mubice bigenda bigaragara.

selulose ethers yerekana ibyiciro byinshi bya polymers hamwe nibikorwa byinshi mubikorwa byinganda. Iterambere ryabo nogushyira mubikorwa byatewe nubushakashatsi burimo gukorwa, iterambere ryikoranabuhanga, no gukenera ibikoresho birambye kandi bifatika mubice bitandukanye.
