Ubudodo bwa Cellulose ni polymer ya sishort yakozwe muri selile karemano binyuze mumiti. Uburenganzira bwa Cellulose ni ukomoka kuri selile kamere. Umusaruro wa selile utandukanye na synthetic polymetike. Ibikoresho byayo byibanze ni selile, urujijo rwa polymer. Kubera ubwinshi bwa selile isanzwe, selile ubwayo nta bushobozi afite bwo kwitwara hamwe nabakozi bahorera. Ariko, nyuma yo kuvurwa umukozi kubyimba, iminyururu ikomeye hagati yiminyururu irambitse kandi iminyururu irasenyutse, kandi irekurwa ryitsinda rya hydroxyl rihinduka selile igenda ihita ihinduka alkali. Shaka selile.
Muguteguye Milling Mortar, ubwinshi bwumukunzi wa selile ni hasi cyane, ariko birashobora kunoza cyane imikorere ya minisiteri itose, kandi nimwe yongeyeho cyane igira ingaruka kumikorere yubwubatsi ya minisiteri. Guhitamo neza abakora selile batandukanye, inzara zitandukanye, ingano zitandukanye, impamyabumenyi zitandukanye zongerwa no kongera ingaruka nziza mugutezimbere ifu yumuntu wumubiri wa minisiteri yumye. Kugeza ubu, Masonry na PlasYING Milling mirisiteri bafite imikorere yubukereya y'amazi, kandi amazi ya slurry azatandukana nyuma yiminota mike yo guhagarara.
Kugumana amazi nigikorwa cyingenzi cya methyl selile, kandi nigikorwa nanone cyumye cyane - kuvanga abakora umuryango wa minisiteri, cyane cyane abakora amajyepfo yubushyuhe, bwitonde kuri. Ibintu bireba ingaruka zogumana amazi yo kumeza minisiteri harimo ingano ya MC yongeyeho, virusi ya MC, ubushyuhe bwibice hamwe nubushyuhe bwo gukoresha ibidukikije.
Imitungo ya ELOVES ZA TELUEPE YITANIRA Ubwoko, umubare no gukwirakwiza abasimbuye. Icyiciro cya elerale ya selile nacyo gishingiye kubwoko bw'abasimbuye, urwego rwo guhinduranya, kwikebana no kubijyanye no gusaba ibintu. Ukurikije ubwoko bwabasimbuye kumurongo wa molekile, irashobora kugabanywamo monoether kandi ivanze ether. MC Mubisanzwe ikoreshwa ni Monoether, na HPMC ivanze ether. Methyl selile ether mc nibicuruzwa nyuma yitsinda rya hydroxyl kuri glucose ishami rya selile karemano ryasimbuwe na Methoxy. Formula yubaka ni [coh7o2 (yewe) 3-h (och3) h] x. Igice cyitsinda rya hydroxyl kuri iyi gice gisimburwa nitsinda, ikindi gice cyasimbuwe nitsinda rya HydroxyPropyl, formulaire yibanze [OH) NETHYS ERT3 yakoreshejwe cyane kandi igurishwa cyane kandi igurishwa ku isoko.
Kubijyanye no kwikengurwa, birashobora kugabanywamo ionic kandi ntabwo ari ionic. Amazi akennye kandi aionic ellic selver yagizwe ahanini na alkyl everst na hydroxyalky. Ionic CMC ikoreshwa cyane cyane mububiko bwa sintetike, gucapa imyenda no gusiga irangi, ibiryo n'ibikoresho bya peteroli. Not-ionic MC, HPMC, HPMC, nibindi bikorwa cyane cyane mubikoresho byubaka, amababi ya latex, ibiti bya buri munsi, nibindi byakoreshwaga nkabakozi, stabilizer na firime.
Kugumana amazi ya selile: Mu gukora ibikoresho byo kubaka, cyane cyane Ether yumye, ubumwe bwa selile bigira uruhare rudasanzwe, cyane cyane mu gukora minisiteri idasanzwe (ni ikintu cyingenzi kandi cyingenzi kandi cyingenzi kandi cyingenzi kandi cyingenzi. Uruhare rwingenzi rwamazi-filleale ether muri minisiteri ifite ibintu bitatu:
1. Ubushobozi bwiza bwo kugumana amazi
2. Ingaruka kuri minisiteri ihumure na thixotropy
3. Imikoranire na sima.
Ingaruka yo kugumana amazi ya selile biterwa no kwinjiza amazi shingiro, imiterere ya minisiteri, ubunini bwa minisiteri ya minisiteri, amazi ya minisiteri, hamwe namazi yo gushiraho ibikoresho. Kugumana amazi ya selile ubwayo biva mubikewe no kubura ubumuga ubwabwo. Nkuko twese tubizi, nubwo urunigi rwa selile rurimo umubare munini wibiryo bya HYDDRATION CYANE, ntabwo bishonga mumazi, kuko imiterere ya selile ifite urwego rwo hejuru rwa kirisiti. Ubushobozi bwa hydration bwamatsinda ya hydroxyl yonyine ntabwo bihagije kugirango dushobore gupfukirana ibihangano bya hydrogen na van der ibitambo biri hagati ya molekile. Kubwibyo, byarabyimbye gusa ariko ntibishonga mumazi. Iyo umusimbuye yatangijwe mumurongo wa molekile, ntabwo asimburwa gusa yangiza urunigi rwa hydrogène, ariko kandi akanagira isuku hydrogène yarasenyutse kubera gushyirwaho umusingi wubatswe hagati yiminyururu yegeranye. Kinini usimbuye, intera nini hagati ya molekile. Intera nini. Ingaruka nini yo gusenya amazu ya hydrogen, ether ether ihinduka amazi nyuma ya kanseri ya selile yaguye hamwe nigisubizo cyinjira, gikora igisubizo kinini. Iyo ubushyuhe buzamutse, hydration ya polymer iragabanya, kandi amazi hagati yiminyururu yirukanwe. Iyo ingaruka zivomera zihagije, molekile zitangira gukusanya, gukora imiyoboro itatu yimiyoboro itatu gel kandi igakuyemo.
