Hydroxyethyl cellulose (hec) ndi polic yopanda madzi yosungunuka yosungunuka yomwe imagwiritsidwa ntchito kwambiri polankhula, zodzoladzola, zozizwitsa ndi zida zomangira. Chifukwa cha kukula kwake, kukhazikika ndi kukhazikika komanso makanema, kumafunikira kusungunuka m'madzi kuti apange yankho la yunifolomu mukamagwiritsa ntchito.
1. Kukonzekera kwachilengedwe
Zida zofunika ndi zida
Hydroxyethyl cellulose ufa
Madzi oyera kapena madzi owoneka bwino
Zida zosangalatsa (monga ndodo zolimbikitsa, zolimbikitsa zamagetsi)
Zotengera (monga galasi, zidebe za pulasitiki)
Kusamalitsa
Gwiritsani ntchito madzi oyera kapena madzi owonetsera kuti mupewe kusazikika.
Hydroxyethyl cellulose imakonda kutentha, ndipo kutentha kwa madzi kumatha kusinthidwa monga kofunikira panthawi yomwe amasungunuka (madzi ozizira kapena njira yotentha yamadzi).
2. Awiri omwe amagwiritsidwa ntchito kawirikawiri
(1) Njira yamadzi ozizira
Pang'onopang'ono kuwaza ufa: mumtsuko wodzaza ndi madzi ozizira, pang'onopang'ono komanso mobwerezabwereza kuwaza ufa kulowa m'madzi kuti athe kuwonjezera ufa wochulukirapo nthawi imodzi kuti abweretse.
Kusunthika ndikumwaza: Gwiritsani ntchito chiwopsezo choti musunthire mwachangu kuti muthe kufalitsa ufa m'madzi kuti apange kuyimitsidwa. Kucheperako kumatha kuchitika panthawiyi, koma osadandaula.
Kuyimirira ndi kunyongedwa: Lolani kuti obalawo azikhala ndi maola 0,5-2 kuti alole ufa kuti uchepetse madzi ndi kutupa.
Pitilizani kusangalatsa: Yerekezerani mpaka yankho liziwoneka bwino kapena silimvanso chabe, zomwe nthawi zambiri zimatenga mphindi 20 mpaka 40.
(2) Njira yotentha yamadzi (njira yotentha yobalalika)
Kubalalika: Onjezani zochepaHecufa mpaka 50-60 ℃ madzi otentha ndikusunthitsa msanga kuti athetse. Samalani kuti mupewe ufa wowuma.
Kuchepetsa kwamadzi ozizira: onjezerani ufa woyamba kubalalika, onjezani madzi ozizira kuti achepetse chidwi cha chandamale ndikusunthira nthawi yomweyo kuti muthandizire kusinthika.
Kuzizira ndi kuyimirira: Yembekezerani yankho kuti muzizire ndikuyimilira kwa nthawi yayitali kuti alole Hec kuti asungunuke kwathunthu.
3..
Pewani kuphatikizika: Mukamawonjezera Hec, kuwaza pang'onopang'ono ndikusungabe. Ngati maulendo atapezeka, gwiritsani yini kuti athe kufalitsa ufa.
Kuthetsa kutentha kwa kutentha: Njira yamadzi ozizira ndi yoyenera mayankho omwe amafunikira kusungidwa kwa nthawi yayitali, ndipo njira yamadzi yofunda imafupikitsa nthawi yowonongeka.
Nthawi Yofalikira: Itha kugwiritsidwa ntchito ngati kuwonekeraku kuli kokwanira, komwe kumatenga mphindi 20 mpaka maola angapo, kutengera ndi zomwe Hec.
4..
Njira yothetsera vutoli: Nthawi zambiri imayang'aniridwa pakati pa 0,5% -2%, ndipo chidwi chake chimasinthidwa malinga ndi zosowa zenizeni.
Kusunga ndi kukhazikika: hec yankho la hec liyenera kusungidwa mumtsuko wosindikizidwa kuti musadetsedwe kapena kuwonekera kutentha kwa malo ake omwe amakhudza kukhazikika kwake.
Kudzera pamwambapa,hydroxyethyl celluloseItha kusungunuka bwino m'madzi kuti apange yunifolomu komanso njira yodziwikiratu, yomwe ndi yoyenera pakugwirira ntchito zosiyanasiyana.
