Hydroxyethyl Cellulose (HEC) ndi polima yosasungunuka m'madzi yomwe imagwiritsidwa ntchito kwambiri popanga zokutira, zodzoladzola, sopo ndi zipangizo zomangira. Chifukwa cha kukhuthala kwake, kukhazikika komanso kupanga filimu, imafunika kusungunuka m'madzi kuti ipange yankho lofanana ikagwiritsidwa ntchito.
1. Kukonzekera kusungunuka
Zida ndi zipangizo zofunika
Ufa wa hydroxyethyl cellulose
Madzi oyera kapena madzi oyeretsedwa
Zipangizo zosakaniza (monga ndodo zosakaniza, zosakaniza zamagetsi)
Zidebe (monga galasi, zidebe za pulasitiki)
Kusamalitsa
Gwiritsani ntchito madzi oyera kapena madzi oyeretsedwa kuti mupewe zinyalala zomwe zingakhudze kusungunuka kwa madzi.
Hydroxyethyl cellulose imakhudzidwa ndi kutentha, ndipo kutentha kwa madzi kumatha kusinthidwa ngati pakufunika panthawi yosungunuka (madzi ozizira kapena njira ya madzi ofunda).
2. Njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri pakusungunula
(1) Njira ya madzi ozizira
Pang'onopang'ono thirani ufa: Mu chidebe chodzaza ndi madzi ozizira, pang'onopang'ono komanso mofanana thirani ufa wa HEC m'madzi kuti mupewe kuwonjezera ufa wochuluka nthawi imodzi kuti upangitse kuti ufawo ukhale wosalala.
Kusakaniza ndi kufalitsa: Gwiritsani ntchito chosakaniza kuti musanganize mofulumira kwambiri kuti mufalitse ufa m'madzi kuti mupange chosakaniza. Kusakanizana kungachitike panthawiyi, koma musadandaule.
Kuyimirira ndi kunyowetsa: Lolani kuti ufawo ukhale kwa maola 0.5-2 kuti ufawo uyamwe madzi ndi kutupa.
Pitirizani kusakaniza: Sakanizani mpaka yankho litakhala lowonekera bwino kapena lopanda granular, zomwe nthawi zambiri zimatenga mphindi 20-40.
(2) Njira yothira madzi ofunda (njira yothira madzi otentha musanawale)
Kufalitsa: Onjezani pang'onoHECUfawo ufike pa madzi otentha a 50-60℃ ndipo sakanizani mwachangu kuti utuluke. Samalani kuti ufawo usamamatire.
Kusungunuka kwa madzi ozizira: Ufa ukayamba kufalikira, onjezerani madzi ozizira kuti musungunuke ku madzi omwe mukufuna ndipo sakanizani nthawi yomweyo kuti musungunuke mwachangu.
Kuziziritsa ndi kuyimirira: Yembekezerani kuti yankho lizizire ndipo liyime kwa nthawi yayitali kuti HEC isungunuke kwathunthu.
3. Njira zazikulu zosungunula
Pewani kusonkhana: Mukawonjezera HEC, ikani pang'onopang'ono ndipo pitirizani kusakaniza. Ngati kusonkhana kwapezeka, gwiritsani ntchito sefa kuti mufalitse ufawo.
Kulamulira kutentha kwa madzi osungunuka: Njira ya madzi ozizira ndi yoyenera pa mayankho omwe amafunika kusungidwa kwa nthawi yayitali, ndipo njira ya madzi ofunda imatha kufupikitsa nthawi yosungunuka.
Nthawi Yosungunula: Itha kugwiritsidwa ntchito pamene kuwonekera bwino kuli koyenera, komwe nthawi zambiri kumatenga mphindi 20 mpaka maola angapo, kutengera zomwe zili mu HEC.
4. Zolemba
Kuchuluka kwa yankho: Kawirikawiri kumayendetsedwa pakati pa 0.5% -2%, ndipo kuchuluka kwake kumasinthidwa malinga ndi zosowa zenizeni.
Kusungira ndi kukhazikika: Yankho la HEC liyenera kusungidwa mu chidebe chotsekedwa kuti lisaipitsidwe kapena kukhudzidwa ndi kutentha kwambiri komwe kumakhudza kukhazikika kwake.
Kudzera mu masitepe omwe ali pamwambapa,hydroxyethyl celluloseIkhoza kusungunuka bwino m'madzi kuti ipange yankho lofanana komanso lowonekera bwino, lomwe ndi loyenera kugwiritsidwa ntchito pazochitika zosiyanasiyana.
