Ethylcellulose ndi polima yosunthika yomwe imagwira ntchito m'mafakitale osiyanasiyana, kuphatikiza mankhwala, zokutira, zomatira ndi zakudya. Magulu osiyanasiyana a ethylcellulose amasinthidwa kuti akwaniritse zofunikira zenizeni malinga ndi kukhuthala, kulemera kwa maselo ndi zinthu zina.
Mapangidwe a Ethyl cellulose:
Ethylcellulose ndi chochokera ku cellulose, polima wachilengedwe wopezeka m'makoma a cellulose. Ethylation ya cellulose imaphatikizapo kuyambitsa magulu a ethyl mu ntchito ya hydroxyl (-OH) ya cellulose. Kusintha kumeneku kumapereka ethylcellulose mawonekedwe apadera, kuwapangitsa kuti asungunuke mu zosungunulira za organic ndikupatsanso luso lopanga filimu.
Makhalidwe a ethylcellulose:
Kusungunuka: Ethylcellulose imasungunuka m'mitundu yosiyanasiyana ya zosungunulira, monga ma alcohols, ketoni, esters, etc.
Zopangira mafilimu: Zopanga bwino kwambiri zopangira mafilimu, zoyenera zokutira ndi mafilimu.
Thermoplasticity: Ethylcellulose imasonyeza khalidwe la thermoplastic, kulola kuti ipangidwe kapena kupangidwa ikatenthedwa.
Inert: Ndi inert yamankhwala, yomwe imapereka kukhazikika pamagwiritsidwe osiyanasiyana.
Magulu a Ethylcellulose:
1. Kalasi yocheperako:
Maphunzirowa ali ndi kulemera kochepa kwa maselo ndipo chifukwa chake amatsika kukhuthala.
Zoyenera kugwiritsa ntchito zomwe zimafuna zokutira zopyapyala kapena makanema.
Zitsanzo zikuphatikizapo mankhwala opangidwa molamulirika komanso zokutira zopyapyala pamapiritsi.
2. Kukhuthala kwapakati:
Kulemera kwa maselo apakati ndi kukhuthala.
Amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala kuti azitha kutulutsa mosalekeza, pomwe kusanja pakati pa makulidwe a zokutira ndi kuchuluka kwa kutulutsa ndikofunikira.
Amagwiritsidwanso ntchito popanga zomatira zapadera komanso zosindikizira.
3. Kukhuthala kwakukulu kalasi:
Maphunzirowa ali ndi kulemera kwakukulu kwa maselo kotero kuti ma viscosity apamwamba.
Zoyenera kugwiritsa ntchito zomwe zimafuna zokutira zokhuthala kapena makanema.
Amagwiritsidwa ntchito popanga zokutira zoteteza monga inki, utoto ndi ma varnish.
4. Fine-grained level:
Maphunzirowa ali ndi tinthu tating'onoting'ono, zomwe zimathandiza kuti zokutira zikhale zosalala komanso kuti zisamabalalike bwino.
Pezani mapulogalamu a inki zosindikizira zapamwamba kwambiri ndi zokutira pokonzekera malo abwino.
5. Makalasi apamwamba a ethoxy:
Ethylcellulose ndi mlingo wapamwamba wa ethoxylation.
Amapereka kusungunuka kowonjezereka mumitundu yambiri ya solvents.
Amagwiritsidwa ntchito pofuna ma polima osungunuka kwambiri, monga mankhwala enaake.
6. Chinyezi chochepa:
Ethyl cellulose yokhala ndi chinyezi chochepa.
Ndibwino kuti mugwiritse ntchito pomwe chinyezi chimakhala chodetsa nkhawa, monga kupanga mankhwala osamva madzi.
7. Thermoplastic giredi:
Makalasi awa akuwonetsa machitidwe owongolera a thermoplastic.
Amagwiritsidwa ntchito poumba zinthu zomwe zimafunikira kufewetsa ndikuwumbidwa pa kutentha kwakukulu.
8. Mulingo wotulutsidwa woyendetsedwa:
Zopangidwira zopangira mankhwala zomwe zimafuna kutulutsidwa kwa mankhwala olamulidwa kwa nthawi yayitali.
Amapangidwa kuti akwaniritse ma kinetics omwe amafunikira ndikusunga bata.
Kugwiritsa ntchito ethylcellulose:
1. Mankhwala osokoneza bongo:
Kuwongolera kumasulidwa kwamankhwala kukonzekera.
Zopaka pamapiritsi zophimba kukoma ndi kusungunuka koyendetsedwa.
Binder ya granules popanga mapiritsi.
2. Zopaka ndi inki:
Kuphimba koteteza kwa malo osiyanasiyana.
Kusindikiza inki za flexographic ndi gravure kusindikiza.
Zovala zamagalimoto ndi mafakitale.
3. Zomatira ndi zosindikizira:
Zomatira zapadera pazogwiritsa ntchito zosiyanasiyana.
Zosindikizira zomwe zimagwiritsidwa ntchito polumikizira ndi kusindikiza pomanga ndi kupanga.
4. Makampani azakudya:
Zopaka zodyedwa pazipatso ndi ndiwo zamasamba zimawonjezera moyo wa alumali.
Kuphatikizidwa kwa zokometsera ndi zonunkhira.
5. Pulasitiki ndi Kuumba:
Makhalidwe a Thermoplastic pakuumba ntchito.
Amapanga zinthu zapulasitiki zapadera.
6. Zamagetsi:
Amagwiritsidwa ntchito popanga zokutira zoteteza pazigawo zamagetsi.
Pomaliza:
Magulu osiyanasiyana a ethylcellulose amapezeka kuti akwaniritse ntchito zosiyanasiyana m'mafakitale osiyanasiyana. Kuchokera kumankhwala kupita ku zokutira ndi zomatira, kusinthasintha kwa ethylcellulose kumakhala m'makalasi ake osiyanasiyana, iliyonse idapangidwa kuti ikwaniritse zosowa zenizeni. Pamene ukadaulo ndi zofunikira zamakampani zikupitilirabe kusinthika, kupangidwa kwa magiredi atsopano a ethylcellulose okhala ndi zinthu zowonjezera kumatha kukhala ndi gawo lalikulu pakukwaniritsa zosowa zamapulogalamu omwe akubwera. Kumvetsetsa kusiyana pakati pa magirediwa kumathandizira opanga kusankha ethylcellulose yoyenera kwambiri pakugwiritsa ntchito kwawo, ndikuwonetsetsa kuti magwiridwe antchito ndi abwino.
