Methylcellulose (MC) ni amazi akomoka kuri selile yamashanyarazi akomoka kubyimbye, gukora firime, gutuza nibindi bintu. Bikunze gukoreshwa mubiribwa, ubuvuzi, ubwubatsi, kwisiga no mubindi bice. Imyitwarire yiseswa ryayo mumazi irihariye kandi biroroshye gukora igisubizo cya colloidal, kuburyo buryo bwiza bwo kuvanga nibyingenzi mubikorwa byabwo.
1. Ibiranga methylcellulose
Methylcellulose ntishobora gushonga byoroshye mubushyuhe bwicyumba, kandi gukomera kwayo bigira ingaruka cyane kubushyuhe. Mu mazi akonje, methylcellulose irashobora gukora igisubizo kimwe mugukwirakwiza buhoro buhoro; ariko mumazi ashyushye, azabyimba vuba na gel. Kubwibyo, kugenzura ubushyuhe nibyingenzi mugihe uvanze methylcellulose namazi.
2. Kwitegura
Methylcellulose: Iraboneka kubikoresho bitanga imiti cyangwa laboratoire.
Amazi: Birasabwa gukoresha amazi yatoboye cyangwa yimuwe kugirango wirinde umwanda mumazi akomeye atagira ingaruka kumyuka ya methylcellulose.
Ibikoresho byo kuvanga: Ukurikije ibyo ukeneye, kuvanga intoki byoroshye, imashini ntoya yihuta, cyangwa ibikoresho byo kuvanga inganda birashobora gukoreshwa. Niba ari laboratoire ntoya, birasabwa gukoresha magnetiki stirrer.
3. Kuvanga intambwe
Uburyo 1: Uburyo bwo gukwirakwiza amazi akonje
Amazi akonje yibanze: Fata amazi akwiye (byaba byiza 0-10 ° C) hanyuma uyashyire mubintu bivanze. Menya neza ko ubushyuhe bwamazi buri munsi ya 25 ° C.
Buhoro buhoro ongeramo methylcellulose: Buhoro buhoro usukamo ifu ya methylcellulose mumazi akonje, ukurura mugihe usuka. Kubera ko methylcellulose ikunda guhubuka, kuyongeramo amazi birashobora kubyara ibibyimba, bikagira ingaruka no gutatana. Kubwibyo, umuvuduko winyongera ugomba kugenzurwa neza kugirango wirinde kongeramo ifu nini ako kanya.
Kuvanga neza: Koresha mixer kumuvuduko wo hagati cyangwa muto kugirango ukwirakwize methylcellulose mumazi. Igihe cyo gukurura biterwa nigisubizo cyanyuma cyifuzwa nubwoko bwibikoresho, kandi muri rusange bimara iminota 5-30. Menya neza ko nta pompe cyangwa uduce twa poro.
Kubyimba: Mugihe gikurura, methylcellulose izagenda ikuramo amazi buhoro buhoro kandi ikabyimba, ikore igisubizo cya colloidal. Iyi nzira irashobora gufata igihe, ukurikije ubwoko nubunini bwa methylcellulose yakoreshejwe. Hejuru ya viscosity methylcellulose ifata igihe kirekire.
Reka wicare ukuze: Nyuma yo gukurura birangiye, nibyiza kureka imvange ikicara amasaha make cyangwa nijoro kugirango urebe ko methylcellulose yashonze kandi yabyimbye rwose. Ibi birashobora kurushaho kunoza ubutinganyi bwigisubizo.
Uburyo bwa 2: Uburyo bubiri bwamazi ashyushye nubukonje
Ubu buryo bukwiranye na methylcellulose igaragara cyane bigoye gukwirakwizwa mumazi akonje.
Amazi ashyushye yibanze: Shyushya igice cyamazi kugeza kuri 70-80 ° C, hanyuma uhite ubyutsa mumazi ashyushye hanyuma ushyiremo methylcellulose. Muri iki gihe, kubera ubushyuhe bwinshi, methylcellulose izaguka vuba ariko ntizashonga burundu.
Gukonjesha amazi akonje: Mugihe ukomeje kubyutsa ubushyuhe bwo hejuru, shyiramo buhoro buhoro amazi akonje asigaye kugeza ubushyuhe bwumuti bugabanutse kubushyuhe busanzwe cyangwa munsi ya 25 ° C. Muri ubu buryo, methylcellulose yabyimbye izashonga mumazi akonje kandi ikore igisubizo gihamye.
Kangura no kureka guhagarara: Komeza kubyutsa nyuma yo gukonja kugirango umenye neza ko igisubizo ari kimwe. Uruvange noneho rusigara rwicaye kugeza rumaze gushonga.
4. Kwirinda
Kugenzura ubushyuhe: Ubushyuhe bwa methylcellulose bwumva cyane ubushyuhe. Mubisanzwe ikwirakwiza neza mumazi akonje, ariko irashobora gukora gel itaringaniye mumazi ashyushye. Kugirango wirinde iki kibazo, mubisanzwe birasabwa gukoresha uburyo bwo gukwirakwiza amazi akonje cyangwa uburyo bubiri kandi bukonje.
Irinde guhuzagurika: Kubera ko methylcellulose yinjira cyane, gusuka ifu nyinshi mumazi bitaziguye bizatera ubuso kwaguka byihuse kandi bibumbwe mubipaki. Ibi ntibireba gusa ingaruka zo guseswa, ariko birashobora no gutuma habaho ubwiza buke bwibicuruzwa byanyuma. Kubwibyo, menya kongeramo ifu gahoro gahoro hanyuma ukangure neza.
Umuvuduko ukurura: Kwihuta kwihuta kurashobora kwinjiza byoroshye umubare munini wibibyimba, cyane cyane mubisubizo bifite ububobere buke. Ibibyimba bizagira ingaruka kumikorere yanyuma. Kubwibyo, gukoresha umuvuduko muke ukurura ni amahitamo meza mugihe ukeneye kugenzura ububobere cyangwa amajwi menshi.
Kwishyira hamwe kwa methylcellulose: Ubwinshi bwa methylcellulose mumazi bugira uruhare runini mukuyisesa no gukemura. Muri rusange, iyo yibanze cyane (munsi ya 1%), igisubizo kiroroshye kandi cyoroshye kubyutsa. Mugihe kinini (kirenze 2%), igisubizo kizahinduka cyane kandi gisaba imbaraga zikomeye mugihe gikurura.
Igihe gihagaze: Mugihe cyo gutegura igisubizo cya methylcellulose, umwanya uhagaze ni ngombwa. Ibi ntabwo byemerera methylcellulose gusa gushonga burundu, ariko kandi bifasha ibituba mubisubizo gucika muburyo busanzwe, birinda ibibazo byububiko mubisabwa nyuma.
5. Ubuhanga bwihariye mugushira mubikorwa
Mu nganda zibiribwa, methylcellulose isanzwe ikoreshwa mugukora umubyimba, stabilisateur cyangwa colloide, nka ice cream, umutsima, ibinyobwa, nibindi. Muri ubu buryo, intambwe yo kuvanga methylcellulose namazi igira ingaruka ku munwa no ku bicuruzwa byanyuma. Umubare wimikoreshereze yibiribwa methylcellulose mubisanzwe ni muto, kandi ugomba kwitabwaho byumwihariko kubipima neza no kwiyongera buhoro buhoro.
Mu rwego rwa farumasi, methylcellulose ikoreshwa nk'umuti usenya ibinini cyangwa nk'ibiyobyabwenge. Muri iki gihe, gutegura ibiyobyabwenge bisaba igisubizo gihanitse cyane ubutinganyi hamwe n’umutekano, bityo rero birasabwa kugenzura ubuziranenge bwibicuruzwa byanyuma wongera buhoro buhoro ububobere no guhitamo ibintu bitera imbaraga.
Kuvanga methylcellulose namazi ninzira isaba kwihangana nubuhanga. Mugucunga ubushyuhe bwamazi, gahunda yo kongeramo numuvuduko ukurura, igisubizo kimwe cya methylcellulose gishobora kuboneka. Yaba uburyo bwo gukwirakwiza amazi akonje cyangwa uburyo bushyushye nubukonje bubiri, icyangombwa nukwirinda guhunika ifu no kwemeza kubyimba no kuruhuka bihagije.
