Ubumwe bwa Cellulose ni ikigo cya polymer kiva muri selile karemano binyuze muburyo bwo guhagarara, kandi ni umukozi ukinga kandi uhari.
Ubushakashatsi
Abahanga muri Celeki bakoreshwaga cyane muri minisiteri humiwe mu myaka yashize, bakoreshwa cyane na selile idasanzwe, harimo Methythyl ) na hydroxypropyl methyl selile (HPMC). Kugeza ubu, nta bitazi byinshi kubwo gupima uburyo bwa virusire ya selile ether igisubizo. Mu gihugu cyacu, amahame amwe n'amwe ateganya uburyo bw'ikizamini cya viscolity ya selile ether igisubizo.
Uburyo bwo gutegura ubugari bwa selile
Gutegura methyl selile ether igisubizo
Methyl Abahanga muri Methoulose Erekeza kuri selile barimo amatsinda ya methyyl muri molekile, nka MC, hemc na HPMC. Kubera Hydrophobicity yitsinda rya methyl, selile ether ibisubizo birimo amatsinda ya methyl afite imitungo yubushyuhe, ni ukuvuga ko bidasubirwaho mumazi ashyushye ku bushyuhe bwabo hejuru yubushyuhe bwabo hejuru yubushyuhe bwabo (hafi 60-80 ° C). Kugirango wirinde igisubizo cya selile cyo gukora agglomerates, shyushya amazi hejuru yubushyuhe bwa gel, nka chardel ether mumazi ashyushye, hanyuma wongere ukwirakwize, Komeza utekereze no gukonjesha no gukonja Ubushyuhe, birashobora gutegurwa muri selile imwe ya selile.
Ibicuruzwa byoroheje byo kutavurwa methylcellsellse-birimo Abami
Kugirango wirinde gukundwa na selile mugihe cyo guturika, rimwe na rimwe bikora imiti ya chimique ku ifu ya selile ya ether ibikomoka ku byaha gutinda. Igikorwa cyacyo kibaho nyuma yubumwe bwa selile biratatanye rwose, bityo birashobora gutatatana mumazi akonje hamwe na ph ya pH idahwitse adafite agglomera. Isumbabyo hejuru ya PH agaciro k'igisubizo, igihe gito cyo kuvugurura igihe cya selile ether hamwe no gutinda kubyuka. Hindura agaciro ka PH agaciro kagaciro keza. Alkalinity izakuraho igisubizo cyatinze cya selile ether, bigatera selile ether kugirango ikore agglomerates iyo ishonga. Kubwibyo, agaciro ka PH gakwiye kuzamurwa cyangwa kumanurwa nyuma yuburenganzira bwa selile bwatatanye rwose.
Umutungo wo kuke cyane wo kuvura methylcellse-urimo abahanga
Gutegura HydroxyAythyl THullease
Hydroxyethyl cellulose ether (HEC) solution does not have the property of thermal gelation, therefore, HEC without surface treatment will also form agglomerates in hot water. Abakora muri rusange bakora ubuvuzi bwo hejuru ya shimi ku ifu ya Shec gutinda guseswa, kugirango bishobore gutatana mumazi akonje hamwe na ph ya ph idahwitse. Mu buryo nk'ubwo, mu gisubizo na alkalinity ndende, hec irashobora kandi gukora agglomera kubera kubura gucika intege. Kuva sima yahagaritswe nyuma ya alkaline nyuma yamaguru hamwe na PH agaciro k'igisubizo ari hagati ya 12 na 13, igipimo cy'imivurungano cya selile yavuwe neza kandi yihuta cyane.

Umwanzuro no gusesengura
1. Gutandukanya inzira
Kugirango wirinde ingaruka mbi mugihe cyibizamini bitewe no gusenya buhoro buhoro, birasabwa gukoresha amazi ashyushye yo kwitegura.
2. Inzira yo gukonjesha
Cellulose Ether Ibisubizo bigomba gukangurwa no gukonjeshwa kubushyuhe bwibidukikije kugirango ugabanye igipimo gikonje, gisaba ibihe byagutse.
3. Inzira ishimishije
Nyuma ya selile ether yongewe kumazi ashyushye, menya neza gukomeza kubyutsa. Iyo ubushyuhe bw'amazi bugabanutse munsi yubushyuhe bwa gel, ether ether izatangira gushonga, kandi igisubizo kizahinduka viscous. Muri iki gihe, umuvuduko ukabije ugomba kugabanuka. Nyuma yuko igisubizo kigera kuri viscosity runaka, gikeneye guhagarara amasaha arenga 10 mbere yuko ibibyimba bireremba buhoro buhoro hejuru kugirango biturika kandi bikarirwe.
Ibituba byo mu kirere muri selile ether igisubizo
4. Inzira yo gukumira
Ubwiza bwa selile n'amazi bigomba gupimwa neza, kandi tukagerageza kudategereza igisubizo cyo kugera ku ruswa rwo hejuru mbere yo kuzuza amazi.
5. Ikizamini cya STCcosity
Bitewe na thixotropi ya selile ether igisubizo, mugihe ugerageza urujijo, iyo rotor ya vicometer yinjijwe mubisubizo, izahungabanya igisubizo kandi igira ingaruka kubisubizo by'ibipimo. Kubwibyo, Rotor yinjijwe mubisubizo, bigomba kwemererwa guhagarara kuminota 5 mbere yo kwipimisha.
