Ni irihe hame rya synthesis ya etherification ya hydroxypropyl methylcellulose?

Hydroxypropyl methylcellulose ikoreshwa nkibikoresho fatizo byo kubyara amavuta, bishobora kumenya ikoreshwa ryisukari yose, kuzamura igipimo cy’ibikoresho fatizo, kugabanya umubare w’ibisigisigi bya substrate mu musemburo wa fermentation, no kugabanya amafaranga yo gutunganya amazi mabi. Iyi hydroxypropyl methylcellulose Ikintu nyamukuru kiranga ni ingirakamaro mu gutezimbere icyiciro, kugaburirwa-hamwe na fermentation ikomeza, kwirinda ibibazo bitandukanye nko kugenzura ibihimbano biciriritse nigipimo cyo kugabanuka; bifasha kandi kugenga gahunda ya fermentation.

Hydroxypropyl methylcellulose, selile yibanze ya selile, irashobora gutunganywa ipamba cyangwa ibiti. Birakenewe cyane kubijanjagura mbere ya alkalisation cyangwa mugihe cya alkalisation. Kumenagura ni ugusenya ibikoresho bya selile ukoresheje ingufu za mashini. Igiteranyo cya leta ya macromolecules ya selile irashobora kugabanya urugero rwa kristalline na polymerisiyasi, ikongera ubuso bwayo, bityo igatezimbere ubushobozi bwimikorere nubushakashatsi bwimiti yibisubizo bigera kumatsinda atatu ya hydroxyl kumatsinda ya glucose ya groupe ya macromolecule.

Nubwo ihame rya synthesis ya etherification ya hydroxypropyl methylcellulose itagoye, ibidukikije bitandukanye byo alkalisation, kumenagura ibikoresho fatizo, etherification, kugarura ibisubizo, gutandukanya centrifugal, gukaraba no gukama birimo umubare munini wikoranabuhanga ryingenzi hamwe nubumenyi bukungahaye. Kubwoko butandukanye bwibicuruzwa, buri bidukikije bifite uburyo bugezweho bwo kugenzura, nkubushyuhe, igihe, igitutu no kugenzura ibintu. Ibikoresho bifasha nibikoresho byo kugenzura ni ingwate nziza kubicuruzwa bihamye hamwe na sisitemu yizewe yizewe.

Kubera ko imikorere ya hydroxypropyl methylcellulose isa nizindi ethers zishonga mumazi, irashobora gukoreshwa mugushushanya irangi rya latx hamwe no gushushanya amazi ya resin yamashanyarazi nkibikoresho bikora firime, kubyimbye, emulisiferi na stabilisateur.

Kora firime itwikiriye ifite imbaraga zo kurwanya kwambara, kuringaniza no gufatana, kandi utezimbere uburinganire bwimbere, guhagarara kuri aside na alkali, no guhuza ibyuma byuma. Hydroxypropyl methylcellulose igira ingaruka nziza nkubyimbye kumazi yera ashingiye kuri polyvinyl acetate. Urwego rwo gusimbuza ether ya selile rwiyongereye, kandi kurwanya isuri ya bagiteri nabyo byiyongera.
