HEC (Hydroxyethyl Cellulose)ndi polima si ion-ayoni madzi sungunuka kwambiri ntchito zokutira, mankhwala tsiku ndi tsiku, zomangamanga, pobowola mafuta, mankhwala, chakudya ndi mafakitale ena monga thickener, stabilizer, dispersant, filimu kupanga wothandizira, etc.
1. Kusungunuka ndi kusungunuka kwa ntchito
HEC ili ndi kusungunuka kwamadzi kwabwino ndipo imatha kusungunuka mwachangu m'madzi ozizira kapena otentha kuti ipange njira yowonekera kapena yowoneka bwino ya viscous. Kusungunula kwake kumakhala kofatsa, sikufuna kumeta mwamphamvu, ndipo sikutulutsa agglomeration, zomwe zimapangitsa HEC kukhala yosavuta kugwiritsa ntchito ntchito zothandiza. Kuonjezera apo, kusungunuka kwa HEC sikukhudzidwa kwambiri ndi pH mtengo, ndipo kumakhala ndi kusintha kwakukulu. Itha kukhala ndi kukhuthala kwabwino kwa pH 2 ~ 12.
2. Kukulitsa magwiridwe antchito
Imodzi mwa ntchito zazikulu za HEC ndikuwonjezera kukhuthala kwa dongosolo. Maselo ake amtundu wa unyolo amanyamula magulu ambiri a hydrophilic, omwe amatha kupanga maukonde amphamvu a haidrojeni okhala ndi mamolekyu amadzi, potero akuwonjezera kukhuthala kwa yankho. Kuchuluka kwa mphamvu ya HEC kumagwirizana ndi kulemera kwake kwa maselo. Kulemera kwa maselo, kumapangitsanso kukhuthala kwake. Zogulitsa za HEC zokhala ndi ma viscosity giredi osiyanasiyana zitha kusankhidwa momwe zimafunikira kuti zikwaniritse zosowa zosiyanasiyana kuchokera kumadzi oyenda kupita kuzinthu ngati gel.
3. Kusintha kwa Rheological
HEC ili ndi luso labwino kwambiri losintha ma rheological. Yankho lake lamadzimadzi limasonyeza khalidwe la pseudoplastic (kumeta ubweya wa ubweya): kukhuthala kumakhala kwakukulu pamene kuyimirira, zomwe zimathandiza kupewa mvula, pamene kukhuthala kumachepa poyambitsa kapena kugwiritsa ntchito mphamvu yometa ubweya, yomwe imapangitsa kuti kupaka, kupopera, kupopera ndi ntchito zina. Katundu wa rheological uyu amapangitsa HEC kukhala yoyenera kwambiri pazinthu zomwe zimafunikira ntchito yomanga kapena kumva, monga utoto wa latex, shampoo, zosamalira khungu, ndi zina zambiri.
4. Kupanga mafilimu ndi kunyowa
HEC imatha kupanga filimu yosinthika komanso yowonekera pambuyo poyanika, yokhala ndi zinthu zabwino zopanga filimu. Katunduyu ndi wofunikira kwambiri m'minda ya zodzoladzola, mafuta odzola, zokutira, ndi zina zambiri. Kuphatikiza apo, HEC imatha kuyamwa chinyezi ndipo imakhala ndi mphamvu yothira, ndipo imakhala ndi ntchito yabwino yogwiritsira ntchito pakhungu ndi mavalidwe amankhwala.
5. Kulekerera kwa mchere ndi kuyanjana
Monga polima yopanda ionic, HEC simvera ma electrolyte ndipo imakhala ndi kulolerana kwamphamvu kwa mchere. HEC ikhoza kukhalabe yokhazikika yolimba mu machitidwe a acidic, alkaline kapena osalowerera ndale. Komanso, akhoza bwino n'zogwirizana ndi zosiyanasiyana surfactants, ma polima, inki ndi fillers ndi zina zowonjezera, ndipo si kophweka kutulutsa mpweya kapena flocculation, amene ali oyenera kachitidwe chilinganizo zovuta.
6. Biodegradability ndi ntchito zachilengedwe
HEC imachokera ku cellulose yachilengedwe ndikusinthidwa ndi etherification. Ili ndi biodegradability yabwino kwambiri komanso yogwirizana ndi chilengedwe. Pakalipano polimbikitsa chitukuko chobiriwira ndi chokhazikika, HEC imatengedwa ngati chowonjezera chothandizira zachilengedwe, choyenera pa mankhwala a tsiku ndi tsiku, chakudya, mankhwala ndi madera ena omwe ali ndi zofunikira zachitetezo.
7. Kuyimitsidwa ndi kukhazikika ntchito
HEC imatha kukhazikika bwino dongosolo lobalalika ndikuletsa kusungunuka kwa tinthu kapena kusanja. Mu zokutira, madzi akubowola m'minda yamafuta, slurries ndi makina ena, HEC imathandizira zida zolimba monga ma pigment, fillers, ndi barite kuyimitsidwa mokhazikika ndikukhuthala ndikuwongolera viscoelasticity, potero kumapangitsa kukhazikika kosungirako ndikufanana kwa dongosolo.
8. Kupititsa patsogolo kukana kwa enzyme
Ma cellulose achilengedwe ndi zotumphukira zake zimawonongeka mosavuta ndi tizilombo tating'onoting'ono, koma zinthu zamakono za HEC nthawi zambiri zimakulitsa kukana kwawo kwa ma enzyme kudzera pamalumikizidwe kapena kusintha kwamapangidwe, kuti athe kukhalabe ndi magwiridwe antchito komanso kukulitsa moyo wautumiki panthawi yosungirako nthawi yayitali kapena m'malo okhala ndi tizilombo tating'onoting'ono.
9. Kugwira ntchito m'mafakitale osiyanasiyana (mwachidule)
Makampani opanga zokutira: sinthani masinthidwe, zomangamanga, kukana kwa splash, ndikupatseni filimu ya utoto kuti ikhale yofanana komanso yofewa;
Makampani opanga mankhwala atsiku ndi tsiku: perekani kukhudza kosalala ndi kuwongolera koyenda mu shampoo ndi gel osamba;
Makampani omanga: kuonjezera kusunga madzi, kumamatira ndi kumanga mu putty ndi matope;
Kubowola mafuta: kukhazika mtima pansi pobowola ndikuwongolera rheology pakubowola madzi;
Mankhwala ndi chakudya: amagwiritsidwa ntchito kwambiri ngati zomatira, zopangira mafilimu, komanso zokometsera zotetezeka.
Zithunzi za HECzakhala zowonjezera zowonjezera m'mafakitale ambiri chifukwa cha kuthekera kwawo kokulirakulira, kusinthasintha kwa pH, kusungunuka kwabwino komanso mawonekedwe oteteza chilengedwe. Mapangidwe ake osakhala a ionic amapatsa kulekerera kwabwino kwa mchere komanso kuyanjana, pomwe ntchito zake zopanga filimu, zosunga chinyezi komanso zowongolera zimakulitsa kuthekera kwake kogwiritsidwa ntchito pamapulogalamu apamwamba. Ndi kupita patsogolo kwaukadaulo komanso zofunikira zoteteza chilengedwe, magwiridwe antchito a HEC apitiliza kukonzedwa bwino ndipo mawonekedwe ake akupitilizabe kukula.
