Ni irihe tandukaniro riri hagati ya selile ether na selile?

Cellulose na selulose ether byombi bikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima.Ariko, bafite itandukaniro ritandukanye mumiterere yimiti nimiterere:

1. Imiterere yimiti: Cellulose numurongo wa polysaccharide ugizwe no gusubiramo ibice bya glucose bihujwe hamwe na β (1 → 4) glycosidic.Numunyururu ugororotse polymer ufite urwego rwo hejuru rwa kristu.
2. Hydrophilicity: Cellulose isanzwe ari hydrophilique, bivuze ko ifitanye isano ikomeye namazi kandi irashobora gukuramo amazi menshi.Uyu mutungo uhindura imyitwarire mubikorwa bitandukanye, harimo imikoranire ya sisitemu ishingiye kumazi nka sima ivanze.
3. Gukemura: Cellulose isukuye ntishobora gushonga mumazi hamwe nudukoko twinshi twinshi kubera imiterere ya kristaline cyane hamwe na hydrogène nini ihuza iminyururu ya polymer.
4. Derivatisation: Cellulose ether nuburyo bwahinduwe bwa selile yabonetse binyuze mumiti.Iyi nzira ikubiyemo kumenyekanisha amatsinda akora, nka hydroxyethyl, hydroxypropyl, methyl, cyangwa carboxymethyl matsinda, kumugongo wa selile.Ihinduka rihindura imiterere ya selile, harimo gukemuka kwayo, imyitwarire ya rheologiya, no gukorana nibindi bintu.
5. Gukemura mu mazi: Ethers ya selile irashobora gushonga cyangwa ikwirakwizwa mumazi, bitewe n'ubwoko bwihariye n'urwego rwo gusimbuza.Ubu busembwa butuma bagira akamaro kanini mubikorwa bitandukanye, harimo imiti, ibiryo, amavuta yo kwisiga, nubwubatsi.
6. Gushyira mu bikorwa: Ethers ya selulose isanga ikoreshwa cyane nkibintu byiyongera, stabilisateur, binders, hamwe nogukora firime muburyo butandukanye bwibicuruzwa nibikorwa.Mu bwubatsi, bakunze gukoreshwa nk'inyongeramusaruro mu bikoresho bishingiye kuri sima kugirango batezimbere imikorere, gufata amazi, gufatira hamwe, nibindi bintu.

Muncamake, mugihe selile na selulose ether bisangiye inkomoko imwe, selulose ether ihindurwa muburyo bwa chimique kugirango itangire imitungo yihariye ituma ikemuka cyangwa ikwirakwizwa mumazi kandi ikwiranye nuburyo butandukanye aho hifuzwa kugenzura imyitwarire ya rheologiya no gukorana nibindi bintu.
