HEC (hydroxyethyl cellulose)chimagwiritsidwa ntchito kwambiri zokutira chifukwa cha thickening kwambiri, mafilimu-kupanga, moisturizing ndi dispersing katundu.
1. Wonenepa
HEC nthawi zambiri imagwiritsidwa ntchito ngati thickener kwa zokutira zokhala ndi madzi, zomwe zimatha kuwonjezera kukhuthala kwa maviscosity ndikupangitsa kuti chophimbacho chikhale chosavuta kuchigwira panthawi yopaka. Chifukwa HEC imasungunuka m'madzi, imatha kupereka zotsatira zokulirapo pamalo otsika, kuthandizira zokutira kukhalabe ndi mawonekedwe abwino a rheological. Izi ndizofunikira makamaka pakugwiritsa ntchito monga kupopera mbewu mankhwalawa ndi kupaka utoto kuti penti isagwere panthawi yopaka.
2. Pangani filimu yophimba yunifolomu
HEC ili ndi zinthu zabwino kwambiri zopangira mafilimu ndipo imatha kupanga filimu yofananira komanso yosalala pakuyanika. Chikhalidwe ichi chimapangitsa HEC kugwiritsidwa ntchito kwambiri muzopaka zamadzi, monga zokutira pakhoma ndi zokutira zamatabwa. HEC imathandizira kukonza zomatira komanso kukana kwamadzi kwamakanema okutira, potero kumathandizira kukhazikika komanso chitetezo cha zokutira.
3. Moisturizing katundu
Pa kuyanika utoto,HECimatha kusunga chinyezi mu utoto, potero kupewa kusweka ndi kusenda chifukwa cha kuyanika mwachangu. Katundu wonyezimirawu ndi wofunikira kwambiri pa zokutira zokhala ndi madzi chifukwa zimakulitsa nthawi yotseguka ya zokutira, zomwe zimapatsa wogwiritsa ntchito nthawi yochulukirapo kuti agwiritse ntchito.
4. Kusintha rheological katundu
HEC imatha kusintha mawonekedwe a rheological of zokutira kuti awonetse ma viscosities osiyanasiyana pansi pamikhalidwe yosiyanasiyana yakumeta ubweya. Pansi pamikhalidwe yotsika, HEC imapereka mamasukidwe apamwamba kuti asunge kukhazikika kwa zokutira, pomwe pansi pamikhalidwe yometa ubweya wambiri, kukhuthala kumachepa kuti athandizire kuyanika. Kumeta ubweya wa ubweya uku kumapangitsa utoto kukhala wamadzimadzi kwambiri panthawi yopopera ndi kupopera, zomwe zimapangitsa kuti zikhale zosavuta kukwaniritsa ngakhale zokutira.
5. Obalalika
HEC imagwiranso ntchito ngati dispersant kuthandiza kumwaza inki ndi fillers mu zokutira. Powonjezera kubalalitsidwa kwa ma pigment ndi ma fillers mu zokutira, HEC imatha kukonza kusasinthika kwamtundu komanso kubisala kwa zokutira. Izi ndizofunikira kwambiri popanga utoto wapamwamba kwambiri, makamaka pazopaka utoto zomwe zimafunikira mtundu wofananira komanso gloss wapamwamba.
6. Makhalidwe oteteza chilengedwe
Pamene malamulo a chilengedwe akuchulukirachulukira, kufunikira kwa zokutira zokhala ndi madzi kukukulirakulira. Monga polima wachilengedwe, zida za HEC ndizongongowonjezwdwa komanso zokomera chilengedwe, ndipo zimatha kuchepetsa kutulutsa kwamafuta osakhazikika (VOC) akamagwiritsidwa ntchito zokutira, potsatira zofunikira zachitetezo cha chilengedwe chamakampani amakono opanga zokutira.
7. Zitsanzo zogwiritsira ntchito
M'magwiritsidwe ntchito,HECchimagwiritsidwa ntchito kwambiri zokutira zomangamanga, zokutira mafakitale, zokutira matabwa, zokutira magalimoto ndi zina. Mwachitsanzo, mu zokutira zomangamanga, HEC ikhoza kupititsa patsogolo kukana kwa madontho ndi kukana kwa nyengo ya zokutira; mu zokutira matabwa, HEC akhoza kusintha gloss ndi kuvala kukana ❖ kuyanika filimu.
Kugwiritsa ntchito kwa HEC mumakampani opanga zokutira kumawonetsa bwino kwambiri zinthu zake zakuthupi ndi zamankhwala. Monga thickener, filimu kale ndi dispersant, HEC akhoza kwambiri kusintha ntchito ndi khalidwe zokutira. Pomwe makampani opanga zokutira akupitilizabe kuteteza chilengedwe komanso magwiridwe antchito apamwamba, kufunikira kwa msika wa HEC kukuyembekezeka kupitiliza kukula. Kupyolera mu kafukufuku wozama ndi kugwiritsa ntchito zatsopano pa HEC, opanga zokutira amatha kupanga zinthu zopikisana kwambiri komanso zosinthika pamsika.
