Ni ubuhe bwoko bwa methylcellulose?

1. Irashobora gushonga iyo ishyutswe hejuru ya 200 ° C, kandi ivu riba hafi 0.5% iyo ritwitswe, kandi ntiribogamye nyuma yo gukorwamo amazi. Kubijyanye nubwiza bwacyo, biterwa nurwego rwa polymerisation.

2. Amashanyarazi mumazi aringaniye nubushyuhe, ubushyuhe bwo hejuru bufite imbaraga nke, ubushyuhe buke bufite imbaraga nyinshi.

3. Gukemuka mu ruvange rw'amazi n'umuti ukungahaye nka methanol, Ethanol, Ethylene glycol, glycerine na acetone.

4. Iyo umunyu wicyuma cyangwa electrolyte kama ibaho mubisubizo byamazi, igisubizo kirashobora kuguma gihamye. Iyo electrolyte yongewe mubwinshi, gel cyangwa imvura izagaragara.

5. Igikorwa cyo hejuru. Molekile zayo zirimo amatsinda ya hydrophilique hamwe nitsinda rya hydrophobique, bifite emulisile, kurinda colloid hamwe no guhagarara neza.

6. Gutanga ubushyuhe. Iyo igisubizo cyamazi kizamutse mubushyuhe runaka (hejuru yubushyuhe bwa gel), bizahinduka ibicu kugeza igihe biza cyangwa bigwa, bigatuma igisubizo kibura ubukonje, ariko gishobora gusubira muburyo bwacyo mukonje. Ubushyuhe burimo gelation nubushyuhe biterwa nubwoko bwibicuruzwa, kwibumbira hamwe nigipimo cyo gushyuha.

7. Agaciro pH karahagaze. Ubukonje mu mazi ntibwangizwa na aside na alkali. Nyuma yo kongeramo ingano ya alkali, uko ubushyuhe bwaba buri hejuru cyangwa ubushyuhe buke, ntabwo bizatera kubora cyangwa gucamo urunigi.

8. Igisubizo kirashobora gukora firime ibonerana, ikomeye kandi yoroheje hejuru yumye. Irashobora kurwanya ibishishwa kama, amavuta hamwe namavuta atandukanye. Ntabwo izahinduka umuhondo iyo ihuye nurumuri, kandi ntizigaragara nk'imisatsi. Irashobora gushonga mumazi. Niba fordehide yongewe kumuti cyangwa nyuma yo kuvurwa na fordehide, firime ntishobora gushonga mumazi ariko irabyimba igice.

9. Kubyimba. Irashobora kubyimba amazi na sisitemu idafite amazi, kandi ifite imikorere myiza yo kurwanya sag.

10. Kongera ubukonje. Igisubizo cyacyo cyamazi gifite imbaraga zifatika, zishobora kuzamura imbaraga zifatika za sima, gypsumu, irangi, pigment, wallpaper nibindi bikoresho.

11. Ikibazo cyahagaritswe. Irashobora gukoreshwa mugucunga coagulation hamwe nimvura yibice bikomeye.

12. Kurinda colloid kugirango yongere ituze. Irashobora gukumira kwegeranya no gutonyanga ibitonyanga na pigment, kandi bikarinda neza imvura.
