Muri Mortar ivanze, yiyongereyeho ubumwe bwa selile ni hasi cyane, ariko birashobora kunoza cyane imikorere 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.
1. Igitekerezo
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. Mubisanzwe dukoresha MC nka Monoether, na PMC nka ether. Methyl selile ether mc nibicuruzwa nyuma yitsinda rya hydroxyl kuri glucose ishami rya selile karemano yashizwemo ninyubako. 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, Pmc, Hemc, nibindi bikorwa cyane cyane mubikoresho, ubuvuzi, imiti ya buri munsi, nibindi byakoreshejwe nkabakozi, stabilizer, gutabara no gukora firime.
2. Gufunga amazi ya selile
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 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.
Ikomeye ya virusi ya selile ether, imikorere yo kugumana amazi. Viscosity nigipimo cyingenzi cya mc imikorere. Kugeza ubu, abakora ba MC batandukanye bakoresha uburyo n'ibikoresho bitandukanye kugirango bapime vicosity ya MC. Uburyo nyamukuru ni guhosha Rotovisko, hoppler, Ubublohde na Brookfield. Kubicuruzwa bimwe, ibisubizo bya viscosity byapimwe nuburyo butandukanye buratandukanye cyane, ndetse bamwe ndetse banatandukanije kabiri. Kubwibyo, mugihe ugereranya vicosi, bigomba gukorwa hagati yuburyo bumwe bwikizamini, harimo ubushyuhe, rotor, nibindi.
Muri rusange, hejuru cyane viscosiya, ingaruka nziza zo kugumana amazi. Ariko, hejurus viscosiya hamwe nuburemere bwa molekile ya MC, kugabanuka bihuye nibyokundwa bizagira ingaruka mbi ku mbaraga nubwubatsi bwa minisiteri. Hejuru ya virusire, uko byanze bikunze ingaruka kuri minisiteri, ariko ntabwo bigereranyije neza. Isumbuye viscosiya, ni ko bimeze cyane, ni ukuvuga mu gihe cyo kubaka, bigaragarira nko kwizirika ku gishushanyo no gushushanya cyane. Ariko ntabwo ari byiza kongera imbaraga zuburyo bwa minisiteri itose. Mugihe cyo kubaka, imikorere yo kurwanya sag iragaragara. Ibinyuranye nibyo, bamwe mu rubyiruko no hasi ariko bahinduwe Methyl bahanganye na Methyl bafite imikorere myiza mugutezimbere imbaraga zubuntu bwa minisiteri itose.
Umubare munini wa selile wongeyeho kuri minisiteri, imikorere yo kugumana amazi, niziba ndende, imikorere yo kugumana amazi.
Kubijyanye nubunini butandukanye, ibice byiza, byiza kugumana amazi. Nyuma yimiterere minini ya selile ihura namazi, ubuso ako kanya irashonga kandi ikora gel kugirango ireke ibikoresho kugirango wirinde molekile zikomeza kugenda. Rimwe na rimwe ntibishobora gutatana kimwe no gushonga ndetse na nyuma yigihe kirekire, gukora igisubizo cya flocculent cyangwa agglomeration. Bigiraho ingaruka cyane kugumana amazi ya selile, kandi kwikebana ni kimwe mubintu byo guhitamo kuri selile ether.
Ibyiza nabyo ni urutonde rwingenzi rwimikorere ya methyl selile. MC ikoreshwa mu myambaro yumye isabwa kuba ifu, hamwe namazi make, kandi igorofa nayo isaba 20% ~ 60% yubunini butari munsi ya 63um. Ibyiza bigira ingaruka ku kuntu gukemuka methyl selile. Ubusanzwe mc mubisanzwe ni granular, kandi biroroshye gusezererwa mumazi adahuye, ariko igipimo cyo gusebanya kiratinda cyane, bityo ntibikwiriye gukoreshwa muri minisiteri yumye. Mu myanda yumye, MC ikwirakwizwa mu bikoresho byo kubumya nko gukusanya, iyungurura neza na sima ihagije irashobora kwirinda methyl selile iyo kuvanga n'amazi. Iyo MC yongeweho amazi yo gushonga agglomerates, biragoye cyane gutatana no gushonga.
Ubukonje buhebuje bwa MC ntabwo busesagura gusa, ahubwo bigabanya imbaraga zaho za minisiteri. Iyo ifu yumuntu wumye ikoreshwa mu gace kanini, umuvuduko urega wa minisiteri yumye yaho azagabanuka cyane, kandi imirongo izagaragara cyane, kandi imirongo izagaragara kubera ibihe bitandukanye bikiza. Kuri minisiteri yateye hamwe nububiko bwa mashini, icyifuzo cyo kunezeza kiri hejuru kubera igihe gito cyo kuvanga. Ibyiza bya MC nabyo bigira ingaruka runaka kumazi. Muri rusange, kuri methyl selile ya eleralese hamwe nisura imwe ariko ni byiza bitandukanye, mumafaranga yinyongera, umunyamahane mwiza cyane ingaruka zo kugumana amazi.
Kugumana amazi ya MC nabyo bifitanye isano n'ubushyuhe bwakoreshejwe, kandi kugumana amazi ya methyl selile bigabanuka hamwe no kwiyongera k'ubushyuhe. Ariko, muburyo bufatika bwa porogaramu, pewder yifu ikunze gukoreshwa kurubuga rushyushye ku bushyuhe bwo hejuru (hejuru ya dogere 40) mu gihe cy'izuba, nko kwihutisha gukiza sima ndetse n'imyambarire yumye ifu yumye. Kugabanuka kw'igipimo cyo kugumana amazi biganisha ku byiyumvo bigaragara ko gukora imirimo no kurwanya ibihano bigira ingaruka, kandi birakomeye cyane kugirango bigabanye ingaruka z'ubushyuhe muri iyi miterere.
