Hydroxyethyl cellulose (HEC)ndi polima yopanda ionic, yosungunuka m'madzi yochokera ku cellulose yachilengedwe. Chifukwa cha chitetezo chake chapamwamba komanso mphamvu zake zokhazikika, imagwiritsidwa ntchito kwambiri posamalira khungu, kuyeretsa, komanso kupanga zodzoladzola. Ntchito yake pakusamalira khungu siingokhala yokhuthala; ilinso ndi ntchito zambiri, kuphatikizapo kukonza khungu, kukhazikika kwa dongosolo, komanso kuthandiza kupanga filimu.
1. Kapangidwe ndi Katundu
Hydroxyethyl cellulose ndi chinthu chochokera ku cellulose chomwe chimachokera ku thonje lachilengedwe kapena matabwa a matabwa kudzera mu zochita za mankhwala monga alkalization ndi ethylene oxide etherification. Zinthu zomwe zimalowa mu unyolo wake wa mamolekyu zimapangitsa kuti hydroxyethyl isungunuke, zomwe zimathandiza kuti isungunuke m'madzi ozizira komanso otentha kuti ipange njira zowonekera kapena zowonekera za colloidal. Chikhalidwe chake chosakhala cha ionic chimapangitsa kuti chisavutike kwambiri ndi zochita za mankhwala okhala ndi zosakaniza zabwino kapena zoyipa zomwe zili mu kapangidwe kake, zomwe zimapangitsa kuti chikhale chokhazikika pamitundu yosiyanasiyana ya pH ndi ma electrolyte.
2. Ntchito Zofunika Kwambiri Posamalira Khungu
2.1. Kukhuthala ndi Kulamulira Kukhuthala
HEC imatha kuonjezera kwambiri kukhuthala kwa zinthu zosamalira khungu, zomwe zimathandiza kuti madzi azikhala ofanana, gel kapena emulsion. Ikawonjezeredwa ku ma toner, serum, ndi masks a nkhope, imapangitsa kuti mankhwalawa azitha kufalikira komanso kugwiritsidwa ntchito, kupewa kutuluka madzi, komanso kulola kuti afalikire bwino pakhungu.
2.2. Kukhazikitsa Machitidwe a Emulsion
Mu mafuta m'madzi kapena m'madzi monga mafuta odzola ndi mafuta, HEC imatha kuchepetsa kulekanitsa mafuta ndi madzi mwa kuwonjezera kukhuthala kwa gawo lamadzi, motero kumawonjezera kukhazikika kwa emulsion. Izi ndizofunikira kwambiri pamafomula okhala ndi zosakaniza zambiri kapena mafuta osasunthika.
2.3. Kukonza Kumveka kwa Khungu ndi Kupanga Mafilimu
Zinthu zosamalira khungu zomwe zili ndi HEC nthawi zambiri zimapanga filimu yopyapyala, yowonekera bwino, komanso yofewa yoteteza pakhungu, zomwe zimachepetsa kutuluka kwa madzi ndikupereka mawonekedwe osalala komanso osamata. Kapangidwe ka filimuyi ndi kothandiza kwambiri pazinthu zopatsa chinyezi, zotonthoza, komanso zoteteza.
2.4. Kuyimitsidwa ndi Kufalikira
Mu zinthu zosamalira khungu zomwe zili ndi tinthu tosasungunuka (monga zinc oxide, titanium dioxide, ndi ufa wa pearl), HEC imatha kuyimitsa ndikufalitsa tinthu tolimba mofanana mwa kuwonjezera kukhuthala kwa dongosolo ndikupanga kapangidwe ka netiweki ya magawo atatu, kuteteza kusweka kapena kusonkhana.
2.5. Zosakaniza za Fomula Zofatsa Komanso Zotetezeka
HEC, yochokera ku cellulose yachilengedwe, siikwiyitsa komanso siimayambitsa kukwiya, ikutsatira malamulo osiyanasiyana apadziko lonse lapansi okhudza chitetezo cha zodzoladzola. Ilibe ma surfactants ogwira ntchito ndipo siisokoneza chotchinga cha khungu, zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri mu zinthu zosamalira khungu za khungu lofewa kapena makanda.
3. Zitsanzo Zogwiritsira Ntchito mu Zogulitsa Zosiyanasiyana Zosamalira Khungu
Ma Seramu Onyowetsa: Kuchuluka kochepa kwa HEC (0.2%-0.5%) kumawonjezera kusinthasintha kwa madzi ndikuwongolera kugwiritsidwa ntchito, komanso kumalimbitsa kufalikira kwa zinthu zonyowetsa madzi monga hyaluronic acid ndi glycerin mkati mwa dongosolo.
Kirimu ndi Mafuta Odzola: Mlingo wochepera 1% ungathandize kwambiri kukhazikika kwa dongosolo la emulsion, zomwe zimapangitsa kuti phala likhale losalala komanso lofewa.
Zophimba nkhope ndi ma Gel: HEC imapereka mawonekedwe owonekera bwino, ofanana ndi gel ndipo imathandiza kutulutsa zosakaniza zofanana. Choteteza ku dzuwa: Chimagwira ntchito ngati choletsa kuzizira komanso chothandizira kupanga filimu, kuthandiza kufalitsa ufa wa zoteteza ku dzuwa mofanana komanso kukulitsa kufanana ndi kukana madzi kwa filimu yoteteza.
4. Ubwino Wogwiritsa Ntchito
Kugwirizana Kwabwino Kwambiri: Kugwirizana ndi zosakaniza zambiri zosamalira khungu, zonyowetsa khungu, zosungira, ndi zina zambiri.
Kukhazikika Kwambiri: Kokhazikika mkati mwa pH ya 3-11 ndipo sikukhudzidwa ndi ma electrolyte ambiri.
Otetezeka komanso Opanda Chilengedwe: Amawola, mogwirizana ndi mfundo zobiriwira.
Kukonza Kosinthasintha: Komwe kumasungunuka mozizira komanso kotentha, koyenera njira zosiyanasiyana zopangira.
Mtengo wa HEC mu chisamaliro cha khunguSikuti imangokhala yogwira ntchito ngati chokhuthala chofewa komanso chogwira mtima, komanso kuthekera kwake kokonza kapangidwe kake konse, kukulitsa nthawi yogwiritsira ntchito, ndikuwonjezera luso la wogwiritsa ntchito pakhungu. Kaya mu chisamaliro cha khungu cha tsiku ndi tsiku, chisamaliro cha khungu chogwira ntchito, zodzoladzola zamitundu, kapena zodzoladzola zoteteza ku dzuwa, HEC imagwira ntchito yofunika kwambiri popanga mankhwala okhazikika komanso otetezeka, kupereka chithandizo cholimba kuti ntchito yomaliza ya mankhwala igwire bwino ntchito.
