Ubumwe bwa Cellulose ni polymer polymer ikozwe na selile kamere nkibikoresho fatizo kubitekerezo bya shimi. Uburenganzira bwa Cellulose ni ukomoka kuri selile kamere, imisaruro ya selile na synthique polymer iratandukanye, ibikoresho byibanze ni selile, ibice bya polymer. Kubera ubwitonzi bwa selile karemano, selile ubwayo nta bushobozi afite bwo kubyitwaramo hamwe numukozi ushimishije. Ariko nyuma yo kuvurwa umukozi kubyimba, iminyururu ikomeye hagati yiminyururu n'iminyururu yarasenyutse, kandi ibikorwa by'itsinda rya hydroxyl hamwe n'ubushobozi bwo gukora.
Imitungo ya ELOVES ZA TELUEPE YITANIRA Ubwoko, umubare no gukwirakwiza abasimbuye. Ibyiciro bya selile nanone bishingiye kubwoko bw'abasimbuye, urwego rwo guhinduranya, kukesha cyane no gusaba bifitanye isano birashobora gushyirwa mu byiciro. Ukurikije ubwoko bwabasimbuye kumurongo wa molekile, birashobora kugabanywamo kimwe na ether kandi ivanze ether. MC isanzwe ikoreshwa nka ether imwe, mugihe HPMC ivanze ether. Methyl Cellulose Ether MC Ishami risanzwe rya Glucose kuri HLDROXYL RY'UBUYOBOZI BUKURIKIRA formula ni [c6h7o2 (OH) 3-MN (Och3) m [OHC2CH (OH) N na HydroxyEthyyl Methyl Memc, ikoreshwa cyane kandi igurishwa ku isoko.
Kuva muke kwikebana birashobora kugabanywamo ubwoko bwa ionic hamwe nubwoko butari ionic. Amazi-akemuwe ntabwo-filime ya selile igizwe ahanini na alkyl ether na hydroxyl alkyl etherl etherle eshatu zubwoko butandukanye. Ionic CMC ikoreshwa cyane cyane muri terentchic detergent, imyenda, icapiro, ibiryo nibikoresho bya peteroli. NTA-Ionic MC, HPMC, hemc nibindi bikoreshwa cyane mubikoresho byo kubaka, amatara ya latex, ubuvuzi, chimie ya buri munsi nibindi bice. Nkumukozi wibeshya, abakozi bangamiwe namazi, stabilizer, batarasa, umukozi ushinga filime.
Ubugari bwa Cellulose
Mu gukora ibikoresho byo kubaka, cyane cyane byumye Milligh, Ether bigira uruhare rudasubirwaho, cyane cyane mu gukora minisiteri idasanzwe (yahinduwe), ni igice cyingenzi.
Uruhare rwingenzi rwamazi-fillesonal ether muri minisiteri ifite ibintu bitatu, imwe nubushobozi bwiza bwo kugumana amazi, icya kabiri nicyo imbaraga za minisiteri ihumure na Thixotropy, naho iya gatatu ni imikoranire na sima.
Ubugari bwa Cellulose, biterwa nuruhande rwa hydroscopity, abagize minisiteri, ubunini bwa minisiteri, amazi ya mirtar, asaba amazi ya mirtar, igihe cyerekana ibintu bifatika. Kugumana amazi ya selile biva mubikewe no kubura ubumuga ubwabwo. Birazwi neza ko iminyururu ya selile, nubwo irimo umubare munini wa oh hiye yewe, uhumetse mumazi kubera imiterere yabo ya Crystalline. Ubushobozi bwa hydration bwamatsinda ya hydroxyl yonyine ntabwo bihagije kugirango yishyure hydrogène ikomeye ya hydrogène ikomeye na van der waails imbaraga. Iyo abasimbuwe bamenyeshejwe mu ruhererekane ruteye, ntabwo ari ugusenya urunigi rwa hydrogen gusa, ariko kandi kandi ibitsina by'imiyoboro ya syhanani byacitse kubera gushyingiranwa hagati y'iminyururu yegeranye. Nkuru abasimbuye ni, intera nini iri hagati ya molekile ni. Kurimbuka kw'ahungabana rya Hydrogène, kwaguka kwa selile, igisubizo muri selile ether gihinduka amazi, gushiraho igisubizo kinini cya virusi. Ubwo ubushyuhe buzamutse, hydration ya polymer igabanuka kandi amazi hagati yiminyururu yirukanwe. Iyo ingaruka zo gutaha zihagije, molekile zitangira gukusanya hamwe na gel zisohoka mumiyoboro itatu. Ibintu bireba ihohoterwa ryamazi birimo ubumwe bwa ether ethes virusi, dosage, ubushyuhe bwa serivisi nubushyuhe bwa serivisi.
Ikomeye ya virusi ya selile Ether, imikorere yo kugumana amazi, viscosity yo gukemura Polymer. Uburemere bwa Molekolar (urwego rwa polymeration) ya polymer nayo igenwa nuburebure na morphologiya yimiterere ya molekale yumurongo, no gukwirakwiza umubare w'abasimbuye bigira ingaruka muburyo bwa vino. [ETA] = km alpha
Visconsique yimbere yibisubizo bya polymer
M Polymer Uburemere
α Polymer aranga aho
K viscosity igisubizo coeferd
Ibyerekanwe kubisubizo bya Polymer biterwa nuburemere bwa molecmer bwa polymer. Viscosity na kwibanda kuri selile ether ibisubizo bifitanye isano na porogaramu zitandukanye. Kubwibyo, buri selile ya selile ifite ibisobanuro byinshi bitandukanye, amabwiriza ya visosity nabyo ahanini abinyujije kuri selile ya alkali, ni ukuvuga ko kuvunika kwa selile ya selile kugirango abigereho.
Kubunini buranga, ibice byiza, ibyiza byo kugumana amazi. Ibice binini bya selile birahura namazi, ubuso ako kanya bushonga kandi bugakora gel kugirango ukomeze kwishongora, rimwe na rimwe gukomeretsa bidasubirwaho, gushinga igisubizo cyuzuye ibyondo cyangwa agglomerate. Kudakemurwa kwa selile nimwe mubintu byo guhitamo selile.
Kubyimba no kuri thixotropi ya selile
Ingaruka ya kabiri ya selile Ether - Winshinga biterwa na: Cellus Ether EtherériPation Impamyabumenyi, Igisubizo, Igipimo cyometseho, ubushyuhe nibindi. Umutungo wa Farlatique wihariye kuri alkyl selile hamwe nibikomokaho byahinduwe. Ibiranga Gelasiyo bifitanye isano nurwego rwo gusimbuza, kwibanda ku gisubizo ndetse nongeyeho. Kuri Hydroxyl Alkyl yahinduye ibikomokaho, imitungo ya Gel nayo ifitanye isano nurwego rwa hydroxyl alkyl alkyl. Kubisubizo byibibazo bya virusike nkeya MC na HPMC birashobora gutegurwa 10% -15% Igisubizo cya MC na HPMC zirashobora gutegurwa 2% -10% Ibisubizo na HPMC Uburemere bwo hejuru bwa kalliosel ether thickener, kwibanda ku gisubizo, uburemere butandukanye bwa molecmer bufite ubu bukurikira, [η] Uburemere buke bwa kalliolose ether kugirango wongere byinshi kugirango ugere kuri stecosiya. Uruzinduko rwayo ntirushingiye ku gipimo cy'inkomoko, viso ndende kugira ngo igere ku ntego yagenewe, amafaranga akenewe kugirango wongere make, vicosity biterwa no gukora neza. Kubwibyo, kugirango ugere ku buhanitse, umubare runaka wa selile (kwibanda ku gisubizo) n'ibisubizo vicosity bigomba kwemezwa. Ubushyuhe bwa Gelale bwo gukemura umurongo no kwiyongera kwibitirira igisubizo, kandi ifaranga ryabaye ku bushyuhe bwicyumba nyuma yo kugera kubitekerezo runaka. HPMC ifite pelelation ndende mubushyuhe bwicyumba.
Guhuza birashobora kandi guhindurwa muguhitamo ingano ya fagitire na selile bifite impamyabumenyi zitandukanye zo guhindura. Ibibyitwa bifatika ni intangiriro ya hydroxyl alkyl mumatsinda runaka yo gusimbuza kumiterere ya Skeleton ya MC. Muguhindura indangagaciro ugereranije zabasimbuye bombi, ni ukuvuga DS na MS basimbuye indangagaciro za pleesit yuburyo na hydroxyl. Ibintu bitandukanye bya selile birasabwa muguhindura indangagaciro ugereranije zubwoko bubiri bwasimbuwe.
isano iri hagati yo guhuza no guhindura. Mu gishushanyo cya 5, hiyongereyeho ubumwe bwa selile bigira ingaruka ku gukoresha amazi ya minisiteri kandi bihindura umubare w'amazi w'amazi na sima, niyo ngaruka. Hejuru Dosage, ibyo kurya byamazi.
Abahanga ba selile bakoreshaga ibikoresho byubaka ifu bagomba gushonga vuba mumazi akonje kandi bagatanga gahunda hamwe nububasha bwiza. Niba igipimo cy'iminsi mike kiracyari floccculent na colloidal ni impfizi cyangwa ibicuruzwa byiza.
Hariho kandi umubano mwiza wumurongo hagati ya sima uhamye kandi dosage ya selile, ether ya selile irashobora kongera ubuswa bwa minisiteri, urushyi, dosage, biragaragara ko ingaruka.
Cellulose Lather Igisubizo hamwe nisubukuru yo hejuru ifite thixotropy ndende, nikimwe mubiranga selile. Ibisubizo bitangaje bya MC Ubwoko Polymes bukunze kugira amazi meza, adafite thixotropic munsi yubushyuhe bwabo bwa gel, ariko imitungo ya Newtonian ku gipimo cy'iminsi mike. PseudoPPHosti yiyongera hamwe no kwiyongera k'uburemere bwa molekile cyangwa kwibanda kuri selile kandi byigenga ubwoko butazindutse n'urwego. Kubwibyo, abakora selile bo murwego rumwe rwa vinosity, baba MC, HPMC cyangwa HPMC, burigihe berekana imitungo imwe yimiterere mugihe cyose ibitekerezo nubushyuhe bikomeza guhoraho. Iyo ubushyuhe bwiyongereye, gel yubaka yashizweho kandi ibaho cyane. Abashiraho selile bafite ibitekerezo byinshi hamwe na vino nkeya kuri thixotropy ndetse munsi yubushyuhe bwa gel. Uyu mutungo ufite inyungu nini yo kubaka minisiteri yo kubaka kugirango uhindure imitungo yo kumanikwa. Ikeneye gusobanurwa hano ko iri hejuru ya virusi ya selile, ariko hejuru yuburemere bwa selile, igabanya uburemere bukomeye bwa selile, igabanya uburemere bukomeye bwo kwibanda kuri mirtar hamwe nimikorere yubwubatsi. Isumbuye viscosiya, uko bigaragara ingaruka za minisiteri, ariko ntabwo ari umubano wuzuye. Bamwe mu bayobe nke, ariko bahinduye filile bahindukiye mu kuzamura imbaraga z'imiterere y'imiterere itose, hamwe no kwiyongera kwa virusi itera SIDA, ubumwe bwa Cellulose, Gusukura Amazi meza.
