Gukwirakwiza hydroxyethyl selulose (HEC) nigikorwa gisaba intambwe zihariye zigomba gukurikizwa, cyane cyane mubitangazamakuru byamazi. Intambwe nziza yo gutatanya no gusesa irashobora kwemeza ingaruka zayo. Hydroxyethyl selulose ikoreshwa cyane mubitambaro, ibifatika, amavuta yo kwisiga, imirima ya peteroli nindi mirima kubera kubyimbye, gutuza, gukora firime, kubitsa no mubindi bikorwa.
Intangiriro kuri Hydroxyethyl Cellulose
Hydroxyethyl selulose ni amazi-adashonga amazi atari ionic selulose ether yakozwe no guhindura imiti ya selile. Ifite imbaraga nziza zo gukomera no kubyibuha, kandi irashobora gukora igisubizo kibonerana, kibonerana. HEC ifite kandi kwihanganira amazi meza yumunyu, kubwibyo birakwiriye cyane cyane kubidukikije byamazi yinyanja cyangwa sisitemu irimo umunyu. Mugihe kimwe, irashobora kuguma itajegajega mugari ya pH kandi ntabwo ihindurwa na aside hamwe nibidukikije bya alkali.
Ihame ryo gukwirakwiza hydroxyethyl selulose
Mu mazi, inzira yo gukwirakwiza hydroxyethyl selulose ikubiyemo intambwe ebyiri zingenzi: gutatanya amazi no gushonga burundu.
Gukwirakwiza ibishanga: Ubu ni inzira yo gukora hydroxyethyl selile ya selile igabanijwe neza mumazi. Niba HEC yongewemo mumazi, izahita ikurura amazi kandi igire uduce twinshi hejuru, bikabuza gukomeza gushonga. Kubwibyo, mugihe cyo gutatanya, kwibumbira hamwe nkibi bigomba kwirindwa bishoboka.
Iseswa ryuzuye: Nyuma yo guhanagura, molekile ya selile ikwirakwira buhoro buhoro mumazi kugirango ibe igisubizo kimwe. Mubisanzwe, HEC irashonga buhoro kandi irashobora gufata amasaha menshi cyangwa arenga, bitewe nubushyuhe bwamazi, imiterere yimiterere nubunini bwa selile.
Intambwe zo gukwirakwiza hydroxyethyl selulose
Kugirango hydroxyethyl selulose ishobore gukwirakwira, ibikurikira bikoreshwa muburyo bwo gutatanya:
1. Hitamo ubushyuhe bukwiye bwamazi
Ubushyuhe bwamazi nikintu cyingenzi kigira ingaruka ku gukwirakwiza no gusesa hydroxyethyl selulose. Mubisanzwe, amazi akonje cyangwa amazi yubushyuhe bwicyumba nikibanza gikwiye guseswa. Amazi ashyushye (hafi 30-40 ° C) afasha kwihuta gushonga, ariko ubushyuhe bwamazi burenze urugero (hejuru ya 50 ° C) bushobora gutera ibibyimba mugihe cyo gusesa, bizagira ingaruka kumatiku.
2. Kuvura mbere yo kuvoma
Hydroxyethyl selulose ikunda kwibumbira mumazi vuba, kubwibyo kuvura mbere yo guhanagura nuburyo bwiza bwo gukwirakwiza. Mu kubanza kuvanga HEC hamwe n’amazi adashobora gukama amazi (nka Ethanol, propylene glycol, nibindi), HEC itose kimwe kugirango irinde kwinjiza amazi no gukora ibibyimba. Ubu buryo burashobora kunoza cyane imikorere ikwirakwizwa.
3. Kugenzura umuvuduko wongeyeho
Iyo ukwirakwiza hydroxyethyl selulose, ifu igomba gusukwa mumazi buhoro kandi buringaniye mugihe ukurura. Umuvuduko wa stirrer ntugomba kuba mwinshi kugirango wirinde ifuro ryinshi. Niba umuvuduko wongeyeho wihuta cyane, HEC ntishobora gutatanwa byuzuye, ikora micelles zingana, bizagira ingaruka kumikorere ikurikiraho.
4. Gukangura
Gukangura ni imwe mu ntambwe zingenzi muburyo bwo gutatanya. Birasabwa gukoresha moteri yihuta kugirango ikangure ubudahwema kugirango hydroxyethyl selulose ishobora gukwirakwizwa neza muri sisitemu y'amazi. Kwihuta cyane bishobora gutera HEC guhuriza hamwe, kongera igihe cyo gusesa, no kubyara ibibyimba, bigira ingaruka kumucyo wigisubizo. Mubisanzwe, igihe cyo gukurura kigomba kugenzurwa hagati yiminota 30 namasaha menshi, bitewe nibikoresho byakoreshejwe nubushyuhe bwamazi.
5. Ongeramo electrolytite cyangwa uhindure pH
Rimwe na rimwe, inzira yo gusesa hydroxyethyl selulose irashobora kwihuta wongeyeho urugero rukwiye rwa electrolytite (nkumunyu) cyangwa guhindura agaciro ka pH. Ubu buryo burakwiriye cyane cyane kubisabwa bifite ibyangombwa byinshi byo kwihuta. Nyamara, ingano ya electrolyte cyangwa pH igomba guhinduka neza kugirango wirinde kugira ingaruka kumikorere ya HEC.
Ibibazo bisanzwe hamwe ningamba zo guhangana
Agglomeration: Ikibazo gikunze kugaragara muri HEC ni agglomeration mugihe cyo gusesa, biganisha ku gusenyuka kutuzuye. Kugira ngo wirinde ibi, urashobora gukoresha uburyo bwabanjirije guhanagura cyangwa kuvanga HEC nibindi bikoresho byifu (nkibuzuza, pigment, nibindi) hanyuma ukabishyira mumazi.
Igipimo cyo gusenyuka gahoro: Niba igipimo cyo gusesa gitinze, urashobora kwihutisha iseswa wongera imbaraga zo gukurura cyangwa kongera ubushyuhe bwamazi. Mugihe kimwe, urashobora kandi kugerageza gukoresha ako kanya HEC, yavuwe byumwihariko kugirango ishonga vuba mugihe gito.
Ikibazo cyigituba: Ibibyimba byoroshye kubyara mugihe cyo gukurura, bigira ingaruka kumucyo no gupima ibisubizo byumuti. Muri iki gihe, kugabanya umuvuduko ukurura cyangwa kongeramo urugero rukwiye rwo gusebanya birashobora kugabanya neza imiterere yibibyimba.
Gusaba kwirinda hydroxyethyl selulose
Mubikorwa bifatika, ubwoko bukwiye nuburyo bwo kongeramo hydroxyethyl selulose bigomba gutoranywa ukurikije ibisabwa na sisitemu zitandukanye. Kurugero, mubikorwa byo gutwikira, hydroxyethyl selulose ntabwo ikoreshwa gusa mubyimbye, ariko kandi irashobora kunoza imvugo, imiterere ya firime hamwe nububiko buhamye. Mu nganda zikomoka kuri peteroli, kurwanya umunyu wa HEC ni ingenzi cyane, bityo guhitamo bigomba guhinduka ukurikije imiterere yimanuka.
Gukwirakwiza hydroxyethyl selulose nigikorwa cya tekiniki cyane, kandi birakenewe guhitamo uburyo bukwirakwira ukurikije ibintu bitandukanye. Mugucunga ubushyuhe bwamazi, kubanza gutose, kubyutsa neza no kongeramo inyongeramusaruro ikwiye, birashobora kwemeza ko hydroxyethyl selulose ikwirakwizwa kandi igashonga burundu mumazi, bityo bigatuma ibikorwa byayo byiyongera kandi bigahinduka.
