Hydroxyethyl cellulose (HEC) ndi chinthu chofunikira kwambiri chomwe sichinasungunuke m'madzi cha polima chomwe chimagwiritsidwa ntchito mosiyanasiyana pakupanga utoto ndi zokutira.
1. Wonenepa
Hydroxyethyl cellulose ndi othandiza kwambiri thickener. Ikhoza kuonjezera kukhuthala kwa utoto mwa kuyamwa madzi mu njira yamadzimadzi kuti ikule ndikupanga njira ya colloidal. Izi sizimangothandiza kuteteza utoto kuti usakhazikike panthawi yosungiramo ndi kuyendetsa, komanso kumapangitsanso kukula kwake ndi kuyimitsidwa, kuwonetsetsa kuti utoto ukhale wofanana komanso wosalala.
2. Kulamulira zamoyo
Ma cellulose a Hydroxyethyl amatha kusintha mawonekedwe a utoto, ndiye kuti, kusintha mawonekedwe ake otaya pamitengo yosiyanasiyana yometa ubweya. Ikhoza kusunga utoto pa mamasukidwe enaake m'malo osasunthika kuti asagwedezeke; ndipo panthawi yogwiritsira ntchito, viscosity idzachepa ndi kuwonjezeka kwa kumeta ubweya wa ubweya, komwe kuli koyenera kumanga. Katunduyu amathandizira kukonza kamangidwe kake ndi ntchito yabwino ya utoto.
3. Kusunga madzi
Hydroxyethyl cellulose imakhala ndi madzi abwino kwambiri. Zingathe kuteteza bwino kutuluka kwa madzi mofulumira kwambiri, motero kumatalikitsa nthawi yowumitsa utoto ndi kulola kuti filimu ya penti ikhale ndi nthawi yokwanira yokhazikika ndi kupanga filimu panthawi yowumitsa. Izi ndizofunikira makamaka kwa utoto wopangidwa ndi madzi, chifukwa kutayika kwamadzi mwachangu kungayambitse mavuto monga ma pinholes ndi kusweka kwa filimu ya utoto.
4. Kukhazikika ndi kutsutsa-kukhazikitsa katundu
Pakupanga utoto, makamaka makina okhala ndi inki zolimba ndi zodzaza, hydroxyethyl cellulose imatha kupereka kukhazikika kwa kuyimitsidwa kudzera pakukhuthala. Itha kuteteza bwino kusungunuka kwa ma pigment ndi ma fillers, kuwonetsetsa kuti utotowo ukhale wofanana panthawi yosungira, ndikuwonetsetsa kusasinthika kwamtundu komanso kukhazikika kwa zokutira.
5. Kupititsa patsogolo mafilimu opanga mafilimu
Ma cellulose a Hydroxyethyl amatha kupititsa patsogolo mawonekedwe a utoto. Ikhoza kupanga filimu yofananira pamwamba pa zokutira, kuwongolera gloss ndi kufanana kwa filimu ya utoto. Kuphatikiza apo, hydroxyethyl cellulose imathanso kupititsa patsogolo kukana ufa ndi madzi a filimu yokutira, ndikuwonjezera kukhazikika kwake komanso kukongoletsa kwake.
6. Malo otetezedwa ndi chilengedwe
Monga non-ionic thickener, hydroxyethyl cellulose ilibe zitsulo zolemera ndi zosungunulira zoipa, ndipo imakwaniritsa zofunikira zachitetezo cha chilengedwe. Kugwiritsiridwa ntchito kwake mu utoto wopangidwa ndi madzi kumatha kuchepetsa zomwe zili muzinthu zowonongeka (VOCs), zomwe zimathandiza kuchepetsa kuipitsidwa kwa chilengedwe ndi kuvulaza thanzi laumunthu.
Kugwiritsidwa ntchito kwa cellulose ya hydroxyethyl mu utoto sikumangowonjezera mawonekedwe a thupi ndi ntchito yomanga, komanso kumakwaniritsa zofunikira zachitetezo cha chilengedwe komanso chitetezo chamakampani amakono opaka utoto. Monga chowonjezera chamitundu yambiri, chimagwira ntchito yofunika kwambiri pakukonza ndikugwiritsa ntchito utoto.
