Cellulose Ether Itondekanya

Cellulose ether nijambo rusange ryuruhererekane rwibicuruzwa byakozwe nigisubizo cya alkali selulose hamwe na etherifying agent mubihe bimwe. Iyo alkali selulose isimbuwe nibintu bitandukanye bya etherifying, hazaboneka ether zitandukanye za selile.

Ukurikije imiterere ya ionisation yibisimburwa, ethers ya selile irashobora kugabanywamo ibyiciro bibiri: ionic (nka carboxymethyl selulose) na nonionic (nka methyl selulose).

Ukurikije ubwoko bwinsimburangingo, ether ya selile irashobora kugabanywamo kimwe (nka methyl selulose) na ether ivanze (nka hydroxypropyl methyl selulose).

Ukurikije ibisubizo bitandukanye, birashobora kugabanywa muburyo bwo gukemura amazi (nka hydroxyethyl selulose) hamwe no gukama kama (nka Ethyl selulose).

Amazi ya elegitoronike ya selile ikoreshwa muri minisiteri yumye ivanze bigabanijwemo guhita bishonga kandi bivurwa hejuru bitinze-gushonga bya selile.

Itandukaniro ryabo ririhe? Nigute ushobora kubishira muburyo bwa 2% igisubizo cyamazi yo gupima viscosity?

Kuvura hejuru ni iki?

Ingaruka kuri selile?

mbere

Ubuvuzi bwo hejuru nuburyo bwo gukora ibihimbano byububiko hejuru yubutaka bwibanze hamwe nubukanishi, umubiri nubumashini bitandukanye nibyibanze.

Intego yo kuvura hejuru ya ether ya selile ni ugutinza igihe cyo guhuza ether ya selulose namazi kugirango byuzuze buhoro buhoro ibisabwa bya marimari amarangi, kandi no kongera imbaraga zo kwangirika kwa selile ya selile no kunoza ububiko.

Itandukaniro iyo amazi akonje agizwe nigisubizo cyamazi 2%:

Ether-itunganijwe hejuru ya selile irashobora gukwirakwira vuba mumazi akonje kandi ntabwo byoroshye guhurira hamwe kubera ububobere bwayo buhoro;

Ether ya selulose itavuwe hejuru, bitewe nubwiza bwayo bwihuse, izamera mbere yuko ikwirakwizwa mumazi akonje, kandi ikunda guhurira hamwe.

Nigute ushobora gushiraho selile-itavuwe na selile?

1. Banza ushiremo umubare runaka wa selile itavuwe neza;

2. Noneho shyiramo amazi ashyushye kuri dogere selisiyusi 80, uburemere ni kimwe cya gatatu cyamazi asabwa, kugirango gishobore kubyimba no gutatana;

3. Ibikurikira, suka buhoro buhoro mumazi akonje, uburemere ni bibiri bya gatatu byamazi asigaye asabwa, komeza ubyuke kugirango bikomere buhoro, kandi ntihazabaho agglomeration;

4. Hanyuma, ukurikije uburemere bungana, shyira mubwogero bwamazi burigihe kugeza ubushyuhe bugabanutse kugera kuri dogere selisiyusi 20, hanyuma ikizamini cya viscosity kirashobora gukorwa!
