Ukuqeda i-Hydroxyyethyl celtulose (HEC) emanzini kuyinqubo evamile emikhakheni ehlukahlukene, kufaka phakathi ama-Pharmaceuticals, izimonyo kanye nokukhiqizwa kokudla. I-HEC iyi-polymer enikezelanayo engeyona eye-soluble ethathwe ku-cellulose, futhi isetshenziswa kabanzi njengomuntu omkhulu, i-brinder, ne-stabilizer ezisetshenzisweni ezahlukahlukene. Ukuqonda izici ezithinta ukuqedwa kwe-hec emanzini, kanye namasu nezimo ezifanele, kubalulekile ekufezekiseni ukusebenza okufiselekayo ekunikezelweni okuhlukahlukene.
Isingeniso seHydroxYethyl Cellulose (HEC)
I-Hydroxyyethyl celtulose iyinto etholwa yiselula, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. I-Hydroxyethyl Group yethulwa ukuthuthukisa i-soubity yamanzi futhi iguqule izakhiwo ze-cellulose. I-HEC ibonakala ngamandla ayo okwenza izisombululo ezisobala, ezibonakalayo lapho ichithwa emanzini. Izicelo zalo ezahlukahlukene zifaka:
Izemithi: Njengomenzeli wokuqina kumafomu wamadosi aketshezi.
I-COSMETICS: Kukhilimu, ama-lotions, kanye nama-shampoos wezakhiwo zawo zokuqina kanye nokuzinza.
Upende nezimbobo: njengokushintshwa kwe-Rheology.
Imboni yokudla: Kumikhiqizo efana nososo, ukugqoka, nezinto zobisi.
Ukwakhiwa: Njengesengezo sezinto zokwenziwa ngosimende.
Izici ezithinta ukuchithwa kwe-hec emanzini
Kuthonya izici eziningana ukuthobeka kwe-HEC emanzini:
Ukushisa: amazinga okushisa aphezulu ngokuvamile asheshisa inqubo yokuqothula. Kodwa-ke, kungahle kube nomkhawulo ophezulu ngaphezu kwawo-hec angaqala ukungcola.
Ubukhulu bezinhlayiyana: Izinhlayiya ezinhle zinendawo enkulu yendawo, ekhuthaza ukuchithwa okusheshayo. Abakhiqizi bavame ukuhlinzeka ngemihlahlandlela ngosayizi ofanelekile wezinhlayiyana ngomkhiqizo wazo othize we-HEC.
Ukuyaluza: Ukuvusa noma ukuguga isixazululo kusiza ukuhlakazwa kwe-HEC emanzini. Kodwa-ke, ukuguga ngokweqile kungaholela ekufakweni kwama-bubble amoya.
Ph: I-PH ye-PH yezamanzi ingathinta i-solubity ka-HEC. Ngokuvamile kuncibilika kuzo zombili izimo ze-acidic ne-alkaliwe, kepha amanani we-pH athe xaxa kufanele agwenywe.
Amandla we-Ionic: I-HEC iyazwela amandla e-Ionic. Ukugxila okuphezulu kosawoti kungaphazamisa inqubo yokuqothula, futhi kungakuhle ukuthi usebenzise amanzi e-deionized noma afakwe emanzini.
Amasu wokuchithwa
1. Ukulungiselela isixazululo sesitoko:
Qala ngokulinganisa inani elidingekayo le-HEC usebenzisa ibhalansi eqondile.
Sebenzisa isitsha esihlanzekile nesomile ukugwema ukungcoliseka.
Kancane kancane engeza i-HEC emanzini ngenkathi ivuselela ngokuqhubekayo ukuvikela ukuqina.
2. Ukulawulwa kokushisa:
Ngenkathi ungeza i-hec emanzini, gcina izinga lokushisa elilawulwayo. Ngokuvamile, ukudilizwa kwamanzi okufudumele, kepha gwema ukushisa ngokweqile okungalimaza i-polymer.
3. Okuvusa / ukuguga:
Sebenzisa umshushisi noma u-agitator ukuqinisekisa ukuhlakazeka okufanayo.
Govuza ngejubane elilinganiselwe ukuvikela ukonakala ngokweqile noma ukufakwa komoya.
4. Isikhathi se-Hydration:
Vumela isikhathi esanele se-hydration. Le nqubo ingathatha amahora ambalwa, futhi ngezikhathi ezithile kuhlolwe izigaxa noma izinhlayiya ezingalungile.
I-5. I-Filtration / ukucindezela:
Uma izinhlayiya ezingezinhle zikhona, i-filtration noma ukucindezela nge-mesh enhle kungasiza ukufeza isixazululo esishisayo.
6. Ukulungiswa kwe-PH:
Ngenkathi i-HEC ihlala zizinze ngebanga elibanzi le-PH, ezinye izakhi zingadinga ukulungiswa kwe-PH. Qinisekisa ukuthi noma yiluphi ushintsho lwenziwe kancane kancane.
7. Ukuhlolwa kokuhambisana:
Ngaphambi kokufaka i-HEC ekusebenzeni kokugcina, yenza izivivinyo zokuhambisana nezinye izithako ukuze kuqinisekiswe ukuqina nokusebenza.
Ukuxazulula inkinga izindaba ezijwayelekile
Ukwakheka okuhlanganayo noma kwe-lemp:
Qinisekisa ukuthi i-HEC ingezwa kancane kancane ngenkathi ivuselela.
Sebenzisa amazinga okushisa afanele wamanzi ukukhuthaza ukusakazeka.
Foaming:
Lawula ijubane elishukumisayo ukuze linciphise amagwebu.
Uma amagwebu ephikelela, cabanga ukusebenzisa ama-anti-foaming agents.
Ukuhlukaniswa okungaphelele:
Nweba isikhathi se-hydration.
Bheka ukuba khona kwezinhlayiya ezinganqunyelwe futhi uguqule amapharamitha avuselelayo.
Ukuvunywa ngokweqile:
Uma isixazululo siba selumnandi kakhulu, silithambeke ngamanzi ekukhuphukeni okuncane kuze kube yilapho isifiso esifunekayo sitholakala.
Ukugcina
Ukuchithwa kwe-hydroxyethyl celtulose emanzini kuyinto eyisisekelo ebalulekile ezinhlanganweni ezahlukahlukene zezimboni. Ukuqonda izici ezinomthelela ekuqothulweni, ukuqapha amasu afanele, kanye nokubhekana nezinkinga ezijwayelekile kubalulekile ukuze kufezekiswe izakhiwo ozifunayo kumkhiqizo wokugcina. Ukuhlolwa njalo kwezindlela zokulawula ikhwalithi kufanele kwenziwe ukuze kuqinisekiswe ukusebenza okungaguquki kwe-HEC ngezimboni ezahlukahlukene.
