Uburyo selile ya selile itezimbere hamwe no gukora firime

Ether ya selulose nicyiciro cyingenzi cyibintu bya polymer bikoreshwa cyane mubwubatsi, gutwikira, imiti nizindi nzego. Imiterere yihariye yimiti nimiterere yumubiri itanga ibyiza byingenzi mugutezimbere hamwe no gukora firime.

1. Ibintu shingiro bya selile ethers
Ether ya selile ni ubwoko bwa polymer-soluble polymer yabonetse muguhindura imiti ya selile naturel. Imiterere yibanze ni urunigi rwa macromolecular rugizwe na β-D-glucose ibice bihujwe na β-1,4-glycosidic. Ethers isanzwe ya selile irimo hydroxypropyl methylcellulose (HPMC), methylcellulose (MC), carboxymethylcellulose (CMC), nibindi. .

2. Uburyo bwo kunoza imiterere
Ongera guhuza imiterere: Cellulose ether irashobora gukora igisubizo gihamye cya colloidal mugisubizo. Iki gisubizo cya colloidal kirashobora gukwirakwizwa neza hejuru yubutaka, kuzuza micropores hejuru, no kunoza imiterere. Kurugero, kongeramo HPMC mubikoresho byubwubatsi birashobora kunoza guhuza hagati ya minisiteri nibikoresho fatizo, bigatuma minisiteri ikomera cyane kurukuta.

Kunoza ubushuhe bwubuso bwa substrate: Ether ya selile ifite hydrophilicity nziza kandi irashobora kunoza ingaruka zo gukemura igisubizo hejuru yubutaka, bityo bikongerera imbaraga. Kuvomera ni kimwe mu bintu by'ingenzi bigira ingaruka ku gufatira hamwe. Mugutezimbere ubushuhe, ethers ya selile irashobora guteza imbere ibikoresho byo gutwikira kugirango bitose neza kandi bitwikire hejuru yubutaka.

Kunoza imashini zikoreshwa: Firime yakozwe na selile ya ether mugihe cyo kumisha ifite urwego runaka rwo guhinduka nimbaraga, ibyo bigatuma ether ya selulose ikora imashini yimashini hejuru yubutaka kugirango yongere ifatanye. Izi mikoreshereze yubukanishi ningirakamaro cyane cyane mu gutwikira no gufatira hamwe, bishobora kuzamura neza imiterere yibikoresho.

3. Uburyo bwo kunoza imiterere yo gukora firime
Ibintu byiza cyane byerekana amashusho: Cellulose ether irashobora gukora igisubizo kimwe cyinshi-cyiza cyane nyuma yo gushonga mumazi, kandi irashobora gukora firime ikomeza ibonerana nyuma yo gukama. Iyi firime ifite imbaraga zubukanishi nubworoherane, irashobora gutwikira neza hejuru ya substrate no kunoza imiterere yo gukora film. Mu gutwikira no gufata imiti, imiterere ya firime ya selile ya selile ni ngombwa cyane.

Kubika amazi meza: Cellulose ether ifite amazi meza cyane, ashobora kugumana ubuhehere bukwiye mugihe cyo gukora firime no gukumira inenge ziterwa na firime ziterwa no gukama cyane. Kubika amazi bifasha gukora firime imwe kandi yuzuye, birinda gucika no gukuramo firime. Muri minisiteri yubwubatsi no gutwikira, ibintu bigumana amazi ya selile ya selile birashobora kunoza cyane imikorere yubwubatsi bwibikoresho hamwe nubwiza bwa nyuma bwo gukora firime.

Igenzura umuvuduko wumye: Ether ya selile irashobora guhindura igipimo cyamazi cyamazi mugihe cyo gukora firime, bigatuma gahunda yo gukora firime igenzurwa cyane. Mugucunga umuvuduko wumye, ether ya selile irashobora gukumira guhangayikishwa no gutwarwa vuba na firime ya firime, bityo bikazamura ubwiza n’umutekano bya firime. Mu nganda zimiti, ethers ya selile ikoreshwa mugutwikira imiti, ishobora kugenzura neza umuvuduko wumye wurwego kandi igahuza uburinganire nuburinganire bwurwego.

4. Ingero zo gusaba
Imyubakire yubwubatsi: Kongera HPMC mumabuye yubwubatsi birashobora kunoza cyane guhuza no kubaka imikorere ya minisiteri. Binyuze mu ngaruka zayo no kugumana amazi, HPMC itezimbere guhuza imiterere hagati ya minisiteri nibikoresho fatizo, kandi ikanoza imiterere ya firime ya minisiteri, bigatuma minisiteri yoroshye mugihe cyubwubatsi kandi igakomera nyuma yo gukora firime.

Irangi: Ongeramo selile ya selile kumarangi ashingiye kumazi birashobora kunoza imiterere no gukora firime yibara, bigatuma igifuniko cyoroha kandi cyoroshye. Binyuze mu miterere yayo meza yo gukora firime no kugumana amazi, ether ya selile yemeza ko igifuniko kigizwe na firime yuzuye kandi imwe mugihe cyo kumisha, bikanoza gukomera no kuramba.

Imiti ya farumasi: Mubikorwa byo gutwikira imiti, ether ya selile nka HPMC ikoreshwa mugukora igipande. Imiterere myiza ya firime ya selulose ether hamwe nubushobozi bwo kugenzura umuvuduko wumye birashobora kwemeza uburinganire nuburinganire bwurwego rwimyenda kandi bikanoza umutekano no kurekura ibiyobyabwenge.

Ether ya selile ifite ingaruka zikomeye mugutezimbere hamwe no gukora firime binyuze mubyimbye, kubika amazi, no gukora firime. Ikoreshwa ryayo mubwubatsi, gutwikira, imiti nizindi nzego byerekana neza uruhare rwayo mukuzamura imiterere no gukora firime. Mu bihe biri imbere, hamwe nogukomeza kunoza ikoranabuhanga rya selile ether hamwe niterambere ryibicuruzwa bishya bya selile, selile ether izerekana ibyifuzo byagutse mubikorwa byinshi.
