Ethylcellulose ndi polima yogwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo mankhwala, zokutira, zomatira ndi chakudya. Mitundu yosiyanasiyana ya ethylcellulose imasinthidwa kuti ikwaniritse zofunikira zinazake malinga ndi kukhuthala, kulemera kwa mamolekyulu ndi zinthu zina.
Kapangidwe ka ethyl cellulose:
Ethylcellulose ndi yochokera ku cellulose, polima wachilengedwe womwe umapezeka m'makoma a maselo a zomera. Kuchuluka kwa cellulose kumaphatikizapo kuyika magulu a ethyl mu ntchito ya hydroxyl (-OH) ya cellulose. Kusintha kumeneku kumapatsa ethylcellulose mphamvu zapadera, zomwe zimapangitsa kuti isungunuke mu zosungunulira zachilengedwe komanso kupereka mphamvu zabwino kwambiri zopangira filimu.
Makhalidwe a ethylcellulose:
Kusungunuka: Ethylcellulose imasungunuka m'mitundu yosiyanasiyana ya zinthu zachilengedwe monga ma alcohols, ma ketones, ma esters, ndi zina zotero.
Kapangidwe ka filimu: Kapangidwe ka filimu kabwino kwambiri, koyenera kupakidwa ndi kupakidwa mafilimu.
Kutentha kwa dzuwa: Ethylcellulose imasonyeza khalidwe la kutentha kwa dzuwa, zomwe zimapangitsa kuti ipangidwe kapena kupangidwa ikatenthedwa.
Chosagwira: Ndi chosagwira ntchito mwa mankhwala, chomwe chimapereka kukhazikika mu ntchito zosiyanasiyana.
Mitundu ya Ethylcellulose:
1. Kalasi yotsika ya kukhuthala:
Magulu awa ali ndi kulemera kochepa kwa mamolekyulu ndipo motero kukhuthala kochepa.
Zabwino kwambiri pakugwiritsa ntchito zomwe zimafuna zokutira zopyapyala kapena mafilimu.
Zitsanzo zikuphatikizapo mankhwala opangidwa ndi mankhwala opangidwa ndi mphamvu yolamulira komanso zophimba zopyapyala pa mapiritsi.
2. Kalasi yapakati ya kukhuthala:
Kulemera kwapakati kwa mamolekyulu ndi kukhuthala.
Amagwiritsidwa ntchito kwambiri mumakampani opanga mankhwala popanga mankhwala okhazikika, komwe kuli kofunikira kwambiri pakati pa makulidwe a kupaka ndi kuchuluka kwa kutulutsidwa kwa mankhwala.
Amagwiritsidwanso ntchito popanga zomatira zapadera ndi zomatira.
3. Kalasi yapamwamba kwambiri ya kukhuthala:
Magulu awa ali ndi kulemera kwakukulu kwa mamolekyulu ndipo motero amakhala ndi kukhuthala kwakukulu.
Zabwino kwambiri pakugwiritsa ntchito zomwe zimafuna zokutira zokhuthala kapena mafilimu.
Amagwiritsidwa ntchito popanga zophimba zoteteza monga inki, utoto ndi vanishi.
4. Mulingo wochepa:
Mitundu iyi ili ndi tinthu tating'onoting'ono, zomwe zimathandiza kuti zokutira zikhale zosalala komanso kuti zizitha kufalikira m'njira zosiyanasiyana.
Pezani mapulogalamu a inki zosindikizira zapamwamba komanso zokutira zokonzera malo abwino.
5. Magiredi apamwamba a ethoxy:
Ethylcellulose yokhala ndi ethoxylation yapamwamba kwambiri.
Amapereka kusungunuka kwakukulu mu mitundu yosiyanasiyana ya zosungunulira.
Amagwiritsidwa ntchito pofunikira ma polima osungunuka kwambiri, monga mankhwala enaake.
6. Kuchuluka kwa chinyezi chochepa:
Ethyl cellulose yokhala ndi chinyezi chochepa.
Yabwino kwambiri pakugwiritsa ntchito komwe kumayambitsa vuto la chinyezi, monga kupanga mankhwala omwe amakhudzidwa ndi madzi.
7. Magiredi a Thermoplastic:
Magulu awa akuwonetsa khalidwe labwino la thermoplastic.
Amagwiritsidwa ntchito popanga zinthu zomangira pomwe zinthu ziyenera kufewetsedwa ndikupangidwa ngati kutentha kwambiri.
8. Mulingo wotulutsidwa wolamulidwa:
Yopangidwira mankhwala opangira mankhwala omwe amafunika kutulutsidwa kwa mankhwala olamulidwa kwa nthawi yayitali.
Yopangidwa kuti ikwaniritse kayendedwe ka kutulutsidwa komwe kukufunika pamene ikusunga bata.
Kugwiritsa ntchito ethylcellulose:
1. Mankhwala Osokoneza Bongo:
Mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala oletsa kutupa.
Mapiritsi ophimba kukoma ndi kusungunuka bwino.
Chosungira cha granules popanga mapiritsi.
2. Zophimba ndi inki:
Chophimba choteteza pamalo osiyanasiyana.
Inki zosindikizira za kusindikiza kwa flexographic ndi gravure.
Zophimba zamagalimoto ndi mafakitale.
3. Zomatira ndi zotsekera:
Ma glue apadera ogwiritsidwa ntchito m'njira zosiyanasiyana.
Zomatira zomwe zimagwiritsidwa ntchito polumikiza ndi kutseka pomanga ndi kupanga.
4. Makampani ogulitsa chakudya:
Zophimba pa zipatso ndi ndiwo zamasamba zimawonjezera nthawi yogwiritsira ntchito.
Kuyikamo zokometsera ndi zonunkhira.
5. Mapulasitiki ndi Kuumba:
Kachitidwe ka thermoplastic mu ntchito zoumba.
Amapanga zinthu zapadera zapulasitiki.
6. Zinthu zamagetsi:
Amagwiritsidwa ntchito popanga zokutira zoteteza pazinthu zamagetsi.
Pomaliza:
Mitundu yosiyanasiyana ya ethylcellulose imapezeka kuti ikwaniritse ntchito zosiyanasiyana m'mafakitale osiyanasiyana. Kuyambira mankhwala mpaka zokutira ndi zomatira, kusinthasintha kwa ethylcellulose kuli m'mitundu yake yosiyanasiyana, iliyonse yopangidwa kuti ikwaniritse zosowa zinazake. Pamene ukadaulo ndi zofunikira zamakampani zikupitilira kusintha, kupanga mitundu yatsopano ya ethylcellulose yokhala ndi mawonekedwe owonjezera kungakhale ndi gawo lofunikira pakukwaniritsa zosowa za mitundu yatsopano. Kumvetsetsa kusiyana pakati pa mitundu iyi kumathandiza opanga kusankha ethylcellulose yoyenera kwambiri pakugwiritsa ntchito kwawo, kuonetsetsa kuti ikugwira ntchito bwino komanso moyenera.
