Ibyatsi bya sodium carboxymethyl selile nabyo bigabanyijemo amanota menshi ukurikije uburyo butandukanye. Ibyatsi byo gukaraba ubwoko bwa 10 ~ 70 (munsi ya 100), imipaka yo hejuru ya vinosity ni kuva 200 ~ 1200 yo gukata imitako no mu zindi nganda zingana n'izihiza hejuru. Bose bari hejuru ya 1000, kandi viscosiya yinganda zitandukanye ntabwo arimwe.
Kuberako yacyo akoreshwa.
Viscolity ya sodium carboxymethyl selile ya selile yangiza misa ya molekori ya molekile, gelatin, patin guhuza (ni ukuvuga ingaruka za synorgistic).
Iyo agaciro ka PH ari 7, virusi ya sodium carboxymethyl igisubizo cya selile nicyo kinini, kandi mugihe agaciro cya PH ni 4 ~ 11, birahagaze neza. Carboxymethylcellse muburyo bwicyuma cya alkali na ammonium barashonje mumazi. Amazi ya pical ions ca2 +, mg2 +, Fe2 + irashobora kugira ingaruka kuri viscosiya. Ibyuma biremereye nka feza ,riimini, chromium cyangwa fe3 + birashobora gutuma imvura ibacikanye. Niba kwibanda kuri Ion bigenzurwa, nko kongeramo aside citric ya citric, igisubizo cya virusire gishobora gushingwa, bikavamo gum yoroshye cyangwa bikomeye.
Sodium carboxymethyl selile ni ubwoko bwa selile karemano, muri rusange bikozwe mubintu by'ipamba cyangwa ibibabi by'ibiti nk'ibikoresho bya fatizo kandi bikorerwa aside ya monochlororocetic muri Acide.
Ukurikije ibisobanuro byibikoresho fatizo no gusimbuza hydroxyl hydrogène ya d-glucose ukoresheje impande za Carboxymethyl, ibice bya polymer-bikemura amazi hamwe na gahunda zinyuranye zibisimbuza.
Kuberako sodium carboxymethyl selile ifite ibintu byinshi bidasanzwe kandi byiza, bikoreshwa cyane mumiti ya miliyari ya buri munsi, ibiryo nubuvuzi hamwe nuduti hamwe nundi musaruro winganda.
Kimwe mu bipimo by'ingenzi bya sodium carboxymethyl selile ni vino ya sodium carboxymethyl selile. Agaciro ka sscosity gafitanye isano nibintu bitandukanye nkibitekerezo, ubushyuhe nigipimo cyamashanyarazi. However, factors such as concentration, temperature and shear rate are the external factors that affect the viscosity of sodium carboxymethyl cellulose.
Uburemere bwayo hamwe no gukwirakwiza molekuline nibintu byimbere bigira ingaruka kuri virusi ya sodium carboxymethyl igisubizo cya selile. Kugirango ibikorwa bigenzurwe nibicuruzwa byiterambere rya sodium carboxymethyl selile, ubushakashatsi bwibiro bya molekile bifite agaciro ka molekile hamwe nigipimo cya molekile gifite agaciro kanini.
Amategeko ya Newton muri Rheologiya, nyamuneka soma ibikubiye muri "roologiya" mu chimie yumubiri, biragoye gusobanura mu nteruro imwe cyangwa ebyiri. Niba ugomba kubivuga: Kuko igisubizo cya CMC cyegereye amazi ya Newtonian, guhangayikishwa no gukata kugeza kuri bo igipimo cyaciwe, kandi ubufatanye bungana hagati yabo bwitwa viccosity coeeft cyangwa vinematique.
Isuku ikomoka ku mbaraga hagati y'iminyururu ya selile, harimo ingabo zitatanya na hydrogen. By'umwihariko, ubuso bwa polyemetingina na selile ntabwo ari umurongo wumurongo ahubwo ni imiterere myinshi. Mu gisubizo, selile nyinshi z'amashami ya selile yahujwe kugirango ikore imirongo ya spatial. Imiterere, Ingabo zinini hagati yiminyururu ya molekiri mubisubizo byavuyemo.
Kubyara gutemba mu gisubizo cyo kuringaniza ibikomoka kuri selile, imbaraga hagati y'inyungu za molekile zigomba kuneshwa, bityo igisubizo rero gifite urugero rwinshi rwa polymeri ,s gisaba imbaraga nyinshi kubyara. Kubipimo bya stcosity, imbaraga kuri CMC igisubizo nimbaraga uburemere. Muburyo bwo guhora uburemere, urunigi rwibisubizo bya CMC hamwe nurwego runini rwa polymeriyaine rufite imbaraga nini, kandi urujya n'uruza rutinda. Urupapuro rutinze rugaragaza viscosiya.
Ibyatsi bya sodium carboxymethyl selile bifitanye isano ahanini nuburemere bwa molekile, kandi bifite bike byo gukora hamwe nurwego rwo gusimbuza. Urwego runini rwo gusimbuza, uburemere bwa molekili, kuko uburemere bwa molekile bwa carboxymethyl itsinda rirenze itsinda rya hydroxyl yabanjirije.
Umunyu wa sodium wa selile carboxymethyl ether, ifu ya anionic ether cyangwa ifu yera cyangwa amata, hamwe na tonule ya 0.5-0, hafi ya odor, na hygroscopique. Biroroshye gutatana mumazi kugirango ukore igisubizo cyiboneye, kandi ihujwe no gucika intege nka etanol. PH ya 1% igisubizo cyamazi ni 6.5 kugeza 8.5. Iyo PH> 10 cyangwa <5, virusi ya sodium carboxymethylcellsellsellselcellse iragabanuka cyane, kandi imikorere nibyiza mugihe PH = 7.
Ntabwo bihagaze neza. Uruziji ruzamuka vuba munsi ya 20 ℃, kandi ruhinduka buhoro kuri 45 ℃. Gushyushya igihe kirekire hejuru ya 80 ℃ birashobora guhakana colloid no kugabanya viscosiya nibikorwa kuburyo bugaragara. Birashonje byoroshye mumazi, kandi igisubizo kirasobanutse; Birahamye cyane mu gisubizo cya alkaline, kandi biroroshye kuva Hydrolyze imbere ya aside. Iyo agaciro PH ari 2-3, bizacikamo.
