Ethylcellulose ndi multifunctional polima yochokera ku cellulose poyambitsa magulu a ethyl.Kusintha uku kumapereka mawonekedwe apadera a polima, kuwapangitsa kukhala oyenera ntchito zosiyanasiyana zamafakitale.Chofunikira pakugwiritsa ntchito ethylcellulose m'magawo osiyanasiyana ndikumvetsetsa momwe amasungunuka momwe amakhudzira makonzedwe ake ndikugwiritsa ntchito.
Njira yothetsera ethylcellulose:
Sulubility katundu:
Chifukwa cha hydrophobic ya ethyl substituent, ethylcellulose imasungunuka pang'ono m'madzi.Komabe, imawonetsa kusungunuka mumitundu yambiri ya zosungunulira za organic, ndikupangitsa kuti ikhale yoyenera kwambiri pakugwiritsa ntchito komwe kukana madzi ndikofunikira.Zosungunulira zodziwika bwino za ethylcellulose ndi monga ethanol, ethyl acetate, methylene chloride, ndi toluene.Kusungunuka kumaphatikizapo kuthyola mphamvu za intermolecular mkati mwa polima, kulola kuti zosungunulira zilowe ndikubalalitsa maunyolo a polima.
Zomwe zimakhudza kusungunuka:
Zinthu zingapo zimakhudza kusungunuka kwa ethylcellulose:
Kusankha zosungunulira: Kusankha zosungunulira kumagwira ntchito yofunika kwambiri pakusungunuka.Zosungunulira zokhala ndi kuyanjana kwakukulu kwa ethylcellulose, monga ethyl acetate, zimathamangitsa kusungunuka.
Kutentha: Kuwonjezeka kwa kutentha nthawi zambiri kumawonjezera kuchuluka kwa kusungunuka chifukwa kumapereka mphamvu zowonjezera pakuchitana ndi polima-solvent.Komabe, kutentha kwambiri kungayambitse kuwonongeka.
Kukula kwa tinthu ta polima: Tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono tomwe timatulutsa timadzi tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono tomwe timayambitsa kusungunuka mwachangu.Njira zoyenera zopera kapena kuchepetsa kukula kwa tinthu zingagwiritsidwe ntchito kukhathamiritsa kusungunuka.
Gulu la Polymer: Gulu la ethylcellulose limatsimikiziridwa ndi ethoxy zomwe zili ndi kulemera kwa maselo, zomwe zimakhudza kusungunuka kwake.Zomwe zili pamwamba pa ethoxy nthawi zambiri zimawonjezera kusungunuka.
Kugwedezeka kapena kugwedezeka: Kukondoweza kwa makina kapena kugwedezeka kumathandizira kulowa kwa zosungunulira mu matrix a polima ndikufulumizitsa kusungunuka.
Njira zomwe zimagwiritsidwa ntchito nthawi zambiri zosungunula:
Njira zingapo zitha kugwiritsidwa ntchito pakusungunula ethylcellulose:
Kusakaniza Kusakaniza: Izi zimaphatikizapo kusakaniza ethylcellulose ndi zosungunulira zoyenera ndikuyambitsa kusakaniza mpaka kusungunuka kwathunthu.Njira imeneyi imagwiritsidwa ntchito kwambiri m'ma laboratories.
Kupaka utsi: M'mafakitale, mayankho a ethylcellulose nthawi zambiri amakonzedwa kuti azipaka utoto.Chosungunuliracho chimasanduka nthunzi, ndikusiya filimu yopyapyala ya ethylcellulose pa gawo lapansi.
Hot melt extrusion: Njira iyi imaphatikizapo kutenthetsa chisakanizo cha ethylcellulose ndi zigawo zina kuti chisungunuke ndikuchichotsa kudzera mukufa.Pambuyo kuzirala, ethylcellulose imakhazikika.
Kumvetsetsa mawonekedwe a kusungunuka ndi njira ndikofunikira kuti agwirizane ndi ethylcellulose kuti agwiritse ntchito.
Ntchito zazikulu za ethyl cellulose:
Makampani opanga mankhwala:
Kupaka Piritsi: Ethylcellulose amagwiritsidwa ntchito kwambiri ngati ❖ kuyanika kwamapiritsi kuti apereke kumasulidwa koyendetsedwa ndi kuteteza chogwiritsidwa ntchito chamankhwala.
Microencapsulation: Ndi teknoloji ya microencapsulation yomwe imagwiritsidwa ntchito popereka mankhwala kuti ateteze mankhwala kuzinthu zachilengedwe.
makampani azakudya:
Zovala Zodyera: Ethylcellulose imagwiritsidwa ntchito ngati zokutira zodyedwa pazipatso ndi ndiwo zamasamba kuti ziwonjezere moyo wawo wa alumali ndikusunga mwatsopano.
Paints ndi Zopaka:
Inki ndi zokutira: Ethylcellulose ndi chinthu chodziwika bwino mu inki ndi zokutira, zomwe zimapereka mawonekedwe opangira filimu ndikuwonjezera kukhazikika kwapangidwe.
Makampani apulasitiki:
Chowonjezera cha polima: Chimagwiritsidwa ntchito ngati chowonjezera mu mapulasitiki kuti chiwongolere mawonekedwe awo opangira, kupereka kusinthasintha komanso kulimba.
Zomatira:
Zomatira za Hot Melt: Ethylcellulose imagwiritsidwa ntchito popanga zomatira zotentha kuti zithandizire kukonza zomatira komanso zolumikizana.
Makampani opanga nsalu:
Kukula kwa Textile: Pokonza nsalu, ethylcellulose imagwiritsidwa ntchito popanga nsabwe kuti apereke zokutira zoteteza ku ulusi ndikuwonjezera mphamvu zawo.
zinthu zamagetsi:
Zipangizo za Photovoltaic: Chifukwa cha kupanga filimu ndi dielectric katundu, ethylcellulose angagwiritsidwe ntchito kupanga mafilimu oonda kwa zipangizo zamagetsi, kuphatikizapo maselo a dzuwa.
Zosamalira munthu:
Zodzoladzola zodzoladzola: Zimagwiritsidwa ntchito ngati thickener ndi stabilizer mu zodzoladzola formulations monga creams ndi mafuta odzola.
Kusindikiza kwa 3D:
Zomanga mu 3D kusindikiza: Ethylcellulose angagwiritsidwe ntchito ngati binder mu ndondomeko 3D yosindikiza, kuthandiza kusunga structural kukhulupirika kwa chinthu chosindikizidwa.
Makampani opanga mapepala:
Kupaka Papepala: Ethyl cellulose imagwiritsidwa ntchito ngati zokutira zamapepala kuti zithandizire kuwongolera mawonekedwe ake, kukulitsa kusindikiza komanso kuletsa madzi.
Ethylcellulose imagwira ntchito m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera osungunuka komanso ntchito zambiri.Njira zowonongera ndizofunika kwambiri pakukwaniritsa kuthekera kwawo, kupangitsa mayankho opangidwa mwaluso pazosowa zenizeni.Pamene sayansi ya polima ikupitabe patsogolo, ethylcellulose ikhoza kutenga gawo lofunikira kwambiri pamagwiritsidwe osiyanasiyana azinthu zatsopano, zomwe zimathandizira pakupanga zida zapamwamba ndi zinthu.
