Gukwirakwiza hydroxyethyl selulose (HEC) ninzira yingenzi mubikorwa bitandukanye, harimo imiti, amavuta yo kwisiga, ibiryo, nubwubatsi. HEC ni polymer idafite ionic, amazi-eruble polymer ikomoka kuri selile, ikoreshwa cyane nkumubyimba, utuza, kandi ukora firime. Gukwirakwiza neza HEC ni ngombwa kugirango imikorere yayo igerweho.
Intangiriro kuri Hydroxyethyl Cellulose (HEC)
Hydroxyethyl selulose (HEC) ni polymer itandukanye ikomoka kuri selile ikoresheje guhindura imiti. Bikunze gukoreshwa mu nganda nka:
Imiti ya farumasi: HEC ikoreshwa nka modifier ya viscosity na stabilisateur muburyo butandukanye, harimo imiti yo munwa kandi yibanze.
Amavuta yo kwisiga: HEC ikoreshwa mumavuta, amavuta yo kwisiga, shampo, nibindi bicuruzwa byita kumuntu nkumubyimba hamwe na emulifier.
Ibiryo: Ikoreshwa mubicuruzwa byibiribwa nkibibyimbye, stabilisateur, na gelling agent.
Ubwubatsi: HEC ikoreshwa mubikoresho byubwubatsi nkibara, amata, nibicuruzwa bishingiye kuri sima kugirango bitezimbere imiterere yabyo.
Akamaro ko gutatanya HEC
Gutatanya neza HEC ningirakamaro kugirango ugere kubintu byifuzwa mubicuruzwa byanyuma. Gutatana neza biremeza:
Guhuriza hamwe: Gukwirakwiza kimwe kwa HEC mugisubizo cyangwa matrix.
Imikorere: HEC irashobora gusohoza inshingano zayo, nko kubyimba, gutuza, cyangwa gukora firime.
Imikorere: Kunoza imikorere iranga, harimo kugenzura ibicucu, gutuza, hamwe nimiterere.
Ubukungu: Kugabanya imikorere yimikoreshereze ya HEC, kugabanya imyanda, no kugabanya ibiciro by umusaruro.
Uburyo bwo Gutatanya HEC
1. Imyitozo ya mashini:
Gukangura cyangwa Kuvanga: Koresha imashini zikoresha imashini, imvange, cyangwa homogenizers kugirango ukwirakwize HEC mumashanyarazi cyangwa matrix gahoro gahoro. Hindura umuvuduko wo guhagarika umutima nigihe kirekire ukurikije kwibanda kwa HEC nibisabwa.
Kwihuta-Kwihuta: Koresha moteri yihuta cyangwa homogenizers kugirango ikwirakwizwe vuba, cyane cyane kuri HEC yibanze cyangwa ibisubizo biboneye.
2. Uburyo bwa Hydration:
Imbere-Hydrasiyo: Mbere-gushonga HEC mugice cyumuti wubushyuhe bwicyumba mbere yo kuyongera mubice byingenzi. Ibi byoroshya gutatanya byoroshye kandi birinda guhuzagurika.
Buhoro buhoro Wongeyeho: Ongeramo HEC buhoro buhoro kuri solvent hamwe no guhora ukurura kugirango urebe neza hamwe no gutatanya.
3. Kugenzura Ubushyuhe:
Ubushyuhe bwiza: Komeza uburyo bwo gutatanya kurwego rwubushyuhe bwiza kugirango wongere imbaraga zo gukwirakwiza no gukwirakwiza ibintu bya HEC. Mubisanzwe, ubushyuhe bwicyumba kugeza ubushyuhe buke burakwiriye gukwirakwiza HEC.
Ubwogero bw'amazi ashyushye: Koresha ubwogero bw'amazi ashyushye cyangwa icyombo cya jacketi kugirango ugenzure ubushyuhe mugihe cyo gutatana, cyane cyane kubisabwa bisaba ubushyuhe bwinshi.
4. pH Guhindura:
Ibyiza bya pH: Hindura pH ya solvent cyangwa ikwirakwizwa hagati yuburyo bwiza bwo gukemura no gutatanya HEC. Mubisanzwe, kutabogama kuri alkaline nkeya pH ni byiza gutatanya HEC.
5. Ubuhanga bwogosha bwogosha:
Guhindura igipimo cyogosha: Koresha tekinike yogosha muguhindura igipimo cyogosha mugihe cyo gutatanya. Igipimo kinini cyogosha kirashobora gufasha mukumena HEC hamwe no guteza imbere gutatanya.
Gukoresha ibikoresho bya Rheologiya: Koresha ibikoresho bya rheologiya kugirango ukurikirane kandi ugenzure igipimo cyogosha mugihe cyo gutatanya, urebe neza ko bikwirakwizwa kandi neza.
6. Surfactant Yafashijwe Gutatanya:
Guhitamo Surfactant: Hitamo ibintu bikwiye cyangwa bikwirakwiza ibintu bihuye na HEC hamwe nuburyo bwo gutatanya. Surfactants irashobora kugabanya ubukana bwubuso, kongera ubushuhe, nubufasha mukwirakwiza HEC.
Kwibanda kwa Surfactant: Hindura uburyo bwa surfactants kugirango byorohereze ikwirakwizwa rya HEC bitagize ingaruka kumiterere cyangwa imikorere mubicuruzwa byanyuma.
7. Ultrasonication:
Ikwirakwizwa rya Ultrasonic: Koresha ingufu za ultrasonic mukwirakwiza HEC ukoresheje ultrasonic probe cyangwa ubwogero. Ultrasonication itera kugabanya ingano yubunini, deagglomeration, hamwe no gukwirakwiza ibice bya HEC muri solvent cyangwa matrix.
8. Uburyo bwa Particle Ingano yo Kugabanya:
Gusya cyangwa Gusya: Koresha ibikoresho byo gusya cyangwa gusya kugirango ugabanye ingano ya agregate ya HEC, koroshya gutatanya byoroshye no kunoza ubutinganyi.
Ingano yubunini bwisesengura: Gukurikirana no kugenzura ingano yikwirakwizwa rya HEC itatanye ukoresheje tekinoroji nka laser diffaction cyangwa urumuri rukwirakwiza.
9. Ingamba zo kugenzura ubuziranenge:
Igipimo cya Viscosity: Buri gihe ukurikirane ubwiza bwikwirakwizwa rya HEC mugihe cyo gutatanya kugirango habeho guhuzagurika no kugera kumiterere yamagambo.
Ingano yubunini bwisesengura: Kora ingano yubunini bwisesengura kugirango usuzume akamaro ko gutatanya kandi urebe neza ko igabanywa rimwe rya HEC.
Gukwirakwiza hydroxyethyl selulose (HEC) ni ngombwa kugirango ugere ku mutungo wifuzwa no gukora mubikorwa bitandukanye byinganda. Gukoresha uburyo bukwiye bwo gukwirakwiza, harimo gukanika imashini, tekiniki yo kuyobora, kugenzura ubushyuhe, guhinduranya pH, tekinike yogosha, ubufasha bwa surfactant, ultrasonication, hamwe no kugabanya ingano y’ibice, birashobora gutuma ikwirakwizwa rimwe kandi bikagaragaza imikorere ya HEC mubicuruzwa byanyuma. Byongeye kandi, gushyira mubikorwa ingamba zo kugenzura ubuziranenge nko gupima ubwiza no gusesengura ingano yingirakamaro bifasha gukomeza guhuzagurika no kunoza inzira yo gutatanya. Mugukurikiza aya mabwiriza, abayikora barashobora kuzamura imikorere nubuziranenge bwibikorwa bishingiye kuri HEC mu nganda zitandukanye.
