Uruhare rwa selile ether muri minisiteri yumye

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.

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. Nibicuruzwa byabonetse mugusimbuza igice cyitsinda rya hydroxyl ku gice gifite uburyo hamwe nikindi gice hamwe nitsinda rya hydroxyPropyl. Inzira y'imiterere ni [C6H7O2 (OH) 3-Mn (Och3) m [OHOT2CH THERYLY YIDASANZWE HAMWE, iyi niyo mpamvu nyamukuru ikoreshwa 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 byubaka, cyane cyane Mortar yumye, Ether yavanze, cyane cyane mugukora minisiteri idasanzwe (minisiteri yahinduwe), ni ikintu cyingenzi kandi cyingenzi kandi cyingenzi.

Uruhare rwingenzi rwo gukemura amazi ether muri minisiteri ifite ibintu bitatu, kimwe ni ubushobozi buhebuje bwo kugumana amazi, ikindi ni ingaruka kuri minisiteri, naho iya gatatu ni 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. Ibintu bireba kugumana amazi birimo ubuswa bwa selile ether, amafaranga yongeweho, ibyiza by'ibice n'ubushyuhe.

Isumbuye ya virusi ya selile Ether, imikorere yo kugumana amazi, niziba ndende cyane igisubizo cya polymer. Ukurikije uburemere bwa molecular (impamyabumenyi ya polymery) ya polymer, igenwa no muburebure bwimiterere ya molekeri nuburyo bwurunigi, no gukwirakwiza ubwoko bwabasimbuye kandi bigira ingaruka kuburyo bwa virusiki.

Ibyerekanwe kubisubizo bya polymer biterwa nuburemere bwa molecmer bwa polymer. Viscosity no kwibanda kuri selile ether igisubizo kijyanye no gusaba mumirima itandukanye. Kubwibyo, buri selile elt ifite ibisobanuro byinshi bitandukanye, kandi guhinduranya urujijo bigerwaho cyane cyane no kwangiza selile ya Alkali, ni ukuvuga kumena iminyururu ya selile.
Umubare munini wa selile wongeyeho kuri minisiteri, imikorere yo kugumana amazi, niziba ndende, imikorere yo kugumana amazi.

Kubunini, ibice byiza, byiza kugumana amazi. Reba ishusho ya 3. Nyuma yikigereranyo kinini cya selile contacts hamwe namazi, ubuso ako kanya irashonga kandi igakora gel yo kuzinga ibikoresho kugirango wirinde molekile. Munsi yo gutambuka rimwe zirashonga, gukora igisubizo cya flocculent cyangwa agglomerates. Bigiraho ingaruka cyane kugumana amazi ya selile, kandi kwikebana ni kimwe mubintu byo guhitamo kuri selile ether.

Kubyimba no kuri thixotropi ya selile

Igikorwa cya kabiri cya selile ether - kubyimba, biterwa na: urugero rwa polyyairioriation ya selile ether, kwibanda kumuti, igipimo cyo gusobwa, ubushyuhe nibindi. Umutungo wa dolling wigisubizo urihariye kuri alkyl selile nibikomokaho byahinduwe. Umutungo wa pelelation ufitanye isano nurwego rwo gusimbuza, kwibanda ku gisubizo ndetse nongeyeho. Kuri hydroxyalkyl yahinduye ibikomokaho, imitungo ya gel nayo ifitanye isano nurwego rwo guhindura hydroxyalkyl. Kuri virusike nke MC na HPMC, 10% -15% igisubizo birashobora gutegurwa MC na HPMC birashobora gutegura gusa 1% Uburemere bwo hejuru bwa kalliolose ether bifite imikorere minini. Mu gisubizo kimwe cyo kwibanda, polymers hamwe nuburemere butandukanye bwa molekale bifite ubushishozi butandukanye. Impamyabumenyi. Intego ya Intego irashobora kugerwaho gusa yongeramo umubare munini wa molecular uburemere bwa selile. Uburakari bwayo ntibushingiye gato ku gipimo cy'inkomoko, kandi ubushyuhe bwinshi bugera ku ntego, kandi umubare w'inyongera w'inyongera ni muto, kandi viscometity biterwa n'ububasha bwo gukora neza. Kubwibyo, kugirango ugere ku buryo buhuje, umubare munini wa selile (kwibanda ku gisubizo) no gukemura vicosity bigomba kwemezwa. Ubushyuhe bwa Gel bugabanuka kandi buragabanuka kumurongo hamwe no kwibanda kubisubizo, na gels kubushyuhe bwicyumba nyuma yo kugera kubitekerezo runaka. Umugati wa Slling wa HPMC ni muremure mu bushyuhe bwicyumba.

Guhoraho birashobora kandi guhindurwa muguhitamo ubunini butandukanye kandi uhitamo ectlese ya selire hamwe na dogere zitandukanye zo guhindura. Ibibyitwa bifatika ni ukumenyekanisha urwego runaka rwo gusimbuza amatsinda ya hydroxykyl kumiterere ya Skeleton ya MC. Muguhindura indangagaciro zisumbuye zabasimbuye ebyiri, ni ukuvuga DS na MS basimbuye indangagaciro za plassion yuburyo na hydroxyalkyl dukunze kuvuga. Ibisabwa bitandukanye byimikorere ya selile birashobora kuboneka muguhindura indangagaciro ugereranije zabasimbuye bombi.

Abashiraho selile bakoresha mu bikoresho by'ifu bigomba gushonga vuba mu mazi akonje kandi bagatanga ubukana bukwiye kuri sisitemu. Niba uhabwa igipimo runaka, biracyahinduka flocculent na colloidal block, nikintu kidasibanganye cyangwa ibicuruzwa byiza.

Hariho kandi umubano mwiza hagati yicyaha cya sima Paste hamwe na dosage ya selile. Uburenganzira bwa Cellulose burashobora kongera ubukwe bwa minisiteri. Ingano nini, biragaragara ko ingaruka.

Ubudozi Bukuru bwa Cellulose Ether Igisubizo gifite thixotropy yo hejuru, nikindi kiranga esheri. Ibisubizo bitangaje bya MC Polymes mubisanzwe bifite amazi ya pseudopplastique hamwe nuturere munsi yubushyuhe bwabo bwa gel, ariko imitungo ya Newtonian kumashanyarazi make. Pseudoplastity yiyongera hamwe nuburemere bwa molekile cyangwa kwibanda kuri selile ether, utitaye kubwoko bwasimbuwe nurwego rwo gusimbuza. Kubwibyo, ectlese of the Centre of Stalcosity Umwanya umwe, ntakibazo MC, HPMC, HPMC, izahora yerekana imiterere imwe yimiterere mugihe cyose ibitekerezo nubushyuhe bikomeza guhora. Abashitsi bcyuma bashizweho mugihe ubushyuhe bwazamutse, kandi thixotropic cyane ibaho. Kwibanda cyane hamwe na virusike nkeya evercose erekana thixotropie no munsi yubushyuhe bwa gel. Uyu mutungo ufite inyungu nini kugirango uhindure urwego no kunyeganyega mukubaka minisiteri. Ikeneye gusobanurwa hano ko hejuru ya vino ya selile, ariko hejuru yuburemere bwa selile, hamwe no kugabana nabi kwa selile, kandi igabana rinini rya moleki, hamwe no kugabana nabi cyane mubyifuzo bya mirtar hamwe nibikorwa byubwubatsi. Hejuru ya virusire, niko hagaragaye ingaruka mbi kuri minisiteri, ariko ntabwo bigereranywa rwose. Bimwe mubigereranyo kandi bike cyane, ariko filime yahinduwe ether ifite imikorere myiza mugutezimbere imbaraga za minisiteri itose. Hamwe no kwiyongera kwa viscosiya, kugumana amazi ya selile ether bitera imbere
