Kutulutsa kwa cellose kumaphatikizapo njira zingapo zowonjezera ma cellulose pazinthu zosaphika ndikusinthanso mu cellulose etrase. Cellulose etter ndi mankhwala osinthana ndi mapulogalamu omwe ali m'mafakitale osiyanasiyana, kuphatikizapo makonda, kuphatikiza, chakudya, zopangidwa ndi zomangamanga. Njira zopitira ndizofunikira kuti mupeze cellulose kwambiri, zopangira zopangira cellulose etrade. Zotsatirazi ndi kufotokoza mwatsatanetsatane kwa njira yopitira ya cellulose:
1. Kusankhidwa kwazinthu:
Njira yokoka ikuyamba ndikusankhidwa kwa zida zopangira okhala ndi cellulose. Magwero wamba amaphatikizapo nkhuni, thonje, ndi ulusi wina wobzala. Kusankhidwa kwa zinthu zosaphika kumadalira zinthu monga ma cellulose ether, mtengo wake komanso chinthu chomwe mukufuna.
2. Njira ya Pulp:
Pali njira zambiri zokoka za cellulose, makamaka kuphatikiza kukoka kwa mankhwala ndi kutulutsa makina.
3. Kupukutira kwamankhwala:
Kutulutsa kraft: kumaphatikizapo kuchitira tchipisi nkhuni ndi osakaniza sodium hydroxide ndi sodium sulfide. Njirayi imasungunula liglin, ndikusiya ma virus a cellulosic.
Kutulutsa kwa Sulfite: Kugwiritsa ntchito sulfurous acid kapena bisuulfite kuti muchepetse liggen mu chakudya.
Kuyika kwa organic Sturge: Kugwiritsa ntchito ma solfornt monga Ethanol kapena methal kuti asungunuke chiviniro ndikulekanitsa ma cellulose.
4. Kutulutsa kwamakina:
Kukula kwamiyala kwambiri: kumaphatikizanso nkhuni pakati pamiyala kuti ipatule ulusi.
Kutulutsa kwamakina oyeza: kumagwiritsa ntchito mphamvu yamakina kuti apatule kufinya tchipisi.
5.
Pambuyo pokoka, cellulose imayamba kuchotsa zonyansa ndikuchotsa zodetsa komanso utoto. Chlorine, chlorine dioxide, hydrogen peroxide kapena oxygen angagwiritsidwe ntchito pa nthawi yotentha.
5 .. Kusintha kwa Cellulose:
Pambuyo podziyeretsa, cellulose imasinthidwa kupanga cellose edzoose. Njira zofala zimaphatikizapo kusinthika, kufuula ndi zina zomwe zimachitika kusintha kusintha kwa thupi ndi mankhwala a cellulose.
6. Njira Yakubwezera:
Alkirization: Kuchitira cellulose ndi alkali (nthawi zambiri sodium hydroxide) kupanga alkali.
Kuphatikiza othandizira olemekezeka: alkaline cellulose omwe amakumana ndi othandizira (monga alkyl hallides kapena alkyl oxis) kukhazikitsa magulu a ethel mu cellulose kukhala ma cellulose kukhala ma cellulose kukhala ma cellulose kukhala ma cellulose kukhala ma cellulose kukhala ma cellulose kukhala ma cellulose.
Kusasakaniza: kusokoneza zosasakaniza zomwe zimathetsa zomwe zingachitike ndikupeza ethel ethel ethel etherch.
7. kuchapa ndi kuyanika:
Chithandizo cha ethel ether chimatsukidwa kuti chichotse zopangidwa ndi zosayera. Atatsuka, zinthuzo zimawuma kuti zitheke chinyezi chomwe mukufuna.
8. Kupera ndi kuwunika:
Ma cellulose owuma amatha kukhala pansi kuti apeze tinthu tating'onoting'ono. Kuyika kumagwiritsidwa ntchito kupatula tinthu tosiyanasiyana.
8..
Njira zowongolera zowongolera zimaphatikizidwa kuti zitsimikizire kuti cellulose yolumikizira miyezo yotsimikizika. Izi zimaphatikizapo kuyesa kwa ufa, kuchuluka kwa zolowa m'malo, chinyezi komanso magawo ena oyenera.
9. Kuyika ndi kutumiza:
Mankhwala omaliza a ethel embi adayikidwa ndikugawidwa mafakitale osiyanasiyana. Kunyamula bwino kumatsimikizira kuti malonda amasungidwa nthawi yosungirako ndi mayendedwe.
Kukoka kwa ethel ether ether ndi njira zotsatila zophatikizira zomwe zimaphatikizidwa, njira, kusinthidwa, kusinthana kwa cellulose, kuchapa, kuyanika komanso kuwongolera komanso kuwongolera. Gawo lirilonse ndilofunikira posankha mtundu ndi katundu wa cellulose ethel ether, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito mitundu ingapo. Kuyandikira kwaukadaulo kukupitilizabe kusintha ndikukweza njirazi kuti muwonjezere bwino kwa cellulose etheme.
