Cellulose acetate ndi chinthu chogwiritsidwa ntchito m'njira zosiyanasiyana chomwe chimagwiritsidwa ntchito m'njira zosiyanasiyana. Mu makampani opanga fodya, cellulose acetate tow ndiye chinthu chachikulu chopangira zosefera za ndudu chifukwa cha magwiridwe ake abwino kwambiri osefera. Imagwiritsidwanso ntchito mumakampani opanga mafilimu ndi mapulasitiki popanga mafilimu ojambula zithunzi, mafelemu owonetsera, ndi zogwirira zida. Kuphatikiza apo, cellulose acetate imagwira ntchito ngati chinthu chofunikira kwambiri pa nembanemba, kuphatikiza nembanemba zosefera ndi zinthu zosinthira osmosis, chifukwa cha kutseguka kwake bwino komanso kusankha bwino. Chifukwa cha kuwonongeka kwake komanso kusinthasintha kwake, cellulose acetate ikupitilizabe kuchita gawo lofunikira popanga zinthu zachikhalidwe komanso ntchito zamakono zachilengedwe.
Njira Yosefera ya Cellulose Acetate
1. Kukonzekera ndi Kuchepetsa Kuchuluka kwa Zinthu Zopangira
Njirayi imayamba ndizamkati zamatabwaselulosi, yomwe imayeretsedwa kuti ichotse lignin, hemicellulose, ndi zina zodetsa. Cellulose yoyeretsedwayo imayanjanitsidwa ndiacetic acid, acetic anhydride, ndi zina zoterochothandizirakupanga ma ester a cellulose acetate. Mwa kuwongolera kuchuluka kwa kusintha, mitundu yosiyanasiyana monga diacetate kapena triacetate ingapezeke.
2. Kukonzekera kwa Mayankho Oyeretsera ndi Kuzungulira
Pambuyo pa acetylation, chisakanizo cha reaction chimachotsedwa, ndipo zinthu zina zimachotsedwa. Cellulose acetate imatsukidwa, kuumitsidwa, ndi kusungunuka muacetone kapena acetone - madzi osakanizakupanga yankho lozungulira lofanana. Pa siteji iyi, yankho limadutsakusefakuchotsa tinthu tosasungunuka ndi ma gels, kuonetsetsa kuti zinthuzo zimakhala zolimba komanso zosasunthika.
3. Kupanga ndi Kumaliza kwa Ulusi
Njira yozungulira imakonzedwa pogwiritsa ntchitonjira yozungulira youma, komwe imatulutsidwa kudzera mu spinnerets ndikulimba kukhala ulusi pamene chosungunulira chikusintha. Ulusiwo umasonkhanitsidwa, kutambasulidwa, ndikupanga ulusi wopitilira kukoka kapena ulusi. Mankhwala otsatira monga kutambasula, kukwinya, kapena kumaliza amagwiritsidwa ntchito kuti awonjezere mphamvu za ulusi, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito munduduzoseferansalu, ndi ulusi wapadera.
Pepala Losefera la Great Wall
Pepala losefera la SCY Series
Pepala losefera ili, lomwe lili ndi kapangidwe ka cellulose ndi cationic resin, ndi lothandiza kwambiri posefa njira za cellulose acetate. Limapereka mphamvu zambiri zamakaniko, ma porosity okhazikika, komanso kuchotsa zodetsa zodalirika. Kuchuluka kochepa kwa polyamide epoxy resin (<1.5%) kumatsimikizira kuti zimagwirizana komanso zimakhala zotetezeka pokonza cellulose acetate, kuthandiza kuchotsa tinthu tating'onoting'ono, ma gels, ndi zodetsa zosasungunuka pamene zikusunga kukhazikika kwa mankhwala ndikutsatira miyezo ya chitetezo cha chakudya ndi mankhwala.
Ubwino
Kusefera Kwambiri Mwachangu- Amachotsa bwino tinthu tating'onoting'ono, ma gels, ndi zinthu zosasungunuka kuchokera ku njira za cellulose acetate.
Mphamvu Yamphamvu Yamakina- Mphamvu yophulika ≥200 kPa imatsimikizira kulimba komanso kugwira ntchito bwino pakapanikizika.
KugwirizanaKuyenda pang'onopang'ono– Mpweya wololedwa kulowa (25–35 L/㎡·s) umapereka kuchuluka kodalirika kwa madzi ndi zotsatira zofanana zosefera.
Mapeto
Cellulose acetate ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito mu zosefera, mafilimu, mapulasitiki, ndi nembanemba, chifukwa cha magwiridwe ake komanso kuwonongeka kwa zinthu. Pakupanga, kusefa bwino ndikofunikira kuti zitsimikizire kuyera ndi kukhazikika.
