Cellulose acetate ndi zinthu zosunthika zomwe zimagwiritsidwa ntchito mosiyanasiyana. M'makampani a fodya, ma cellulose acetate tow ndiye chinthu chofunikira kwambiri pazosefera za ndudu chifukwa cha kusefera kwake. Amagwiritsidwanso ntchito m'makampani opanga mafilimu ndi mapulasitiki popanga makanema ojambula zithunzi, mafelemu owonera, ndi zogwirira ntchito. Kuphatikiza apo, cellulose acetate imagwira ntchito ngati chinthu chofunikira kwambiri pama membrane, kuphatikiza zosefera ndi zinthu zosinthira osmosis, chifukwa cha kuthekera kwake komanso kusankha bwino. Ndi biodegradability komanso kusinthika kwake, cellulose acetate ikupitilizabe kugwira ntchito yofunikira pakupanga kwachikhalidwe komanso kugwiritsa ntchito masiku ano zachilengedwe.
Njira Yosefera ya Cellulose Acetate
1. Kukonzekera kwazinthu Zopangira & Acetylation
Njirayi imayamba ndimatabwa a matabwacellulose, yomwe imayeretsedwa kuchotsa lignin, hemicellulose, ndi zonyansa zina. Ma cellulose oyeretsedwa amachitidwa nawoacetic acid, acetic anhydride, ndi achothandizirakupanga cellulose acetate esters. Poyang'anira kuchuluka kwa m'malo, magiredi osiyanasiyana monga diacetate kapena triacetate atha kupezeka.
2. Kuyeretsa & Kuwotcha Kukonzekera Kukonzekera
Pambuyo pa acetylation, zomwe zimasakanikirana sizimakhazikika, ndipo zotulutsa zimachotsedwa. Ma cellulose acetate amatsukidwa, owumitsidwa, ndi kusungunuka mkatiKusakaniza kwa acetone kapena acetone - madzikupanga homogeneous kupota njira. Panthawi imeneyi, yankho limathakuseferakuthetsa tinthu tating'onoting'ono tating'onoting'ono ndi ma gels, kuonetsetsa kusasinthika komanso kukhazikika.
3. Kupanga CHIKWANGWANI & Kumaliza
Njira yozungulira imakonzedwa pogwiritsa ntchitoyouma kupota njira, kumene imatulutsidwa kudzera mu spinnerets ndi kukhazikika mu filaments pamene zosungunulira zimatuluka nthunzi. Ulusiwo amasonkhanitsidwa, kutambasulidwa, ndi kupangidwa kukhala chokokera kapena ulusi wosalekeza. Mankhwala am'mbuyo monga kutambasula, kupukuta, kapena kutsirizitsa amagwiritsidwa ntchito kuti apititse patsogolo mawonekedwe a fiber, kuwapanga kukhala oyenera kugwiritsidwa ntchito mufodyazosefera, nsalu, ndi ulusi wapadera.
Great Wall Sefa Pepala
SCY Series fyuluta pepala
Pepala losefera ili, lomwe lili ndi cellulose komanso kapangidwe kake ka utomoni wa cationic, ndilothandiza kwambiri pakusefa mayankho a cellulose acetate. Amapereka mphamvu zamakina apamwamba, porosity yokhazikika, ndi kuchotsa zonyansa zodalirika. Zomwe zili pansi pa polyamide epoxy resin (<1.5%) zimatsimikizira kuyanjana ndi chitetezo mu cellulose acetate processing, kuthandiza kuchotsa tinthu tating'onoting'ono tating'onoting'ono, ma gels, ndi zonyansa zosasungunuka pamene kusunga kukhazikika kwa mankhwala ndikutsatira zakudya ndi mankhwala.
Ubwino wake
Kusefera Kwapamwamba Kwambiri- Amachotsa bwino tinthu tating'onoting'ono, ma gels, ndi zonyansa zosasungunuka kuchokera ku mayankho a cellulose acetate.
Mphamvu Zamakina Zamphamvu- Kuphulika kwamphamvu ≥200 kPa kumatsimikizira kulimba komanso kugwira ntchito mokhazikika pansi pamavuto.
ZosasinthaPorosity- Kuthekera kwa mpweya woyendetsedwa bwino (25–35 L/㎡·s) kumapereka mayendedwe odalirika komanso zotsatira zosefera zofananira.
Mapeto
Cellulose acetate ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito muzosefera, mafilimu, mapulasitiki, ndi nembanemba, zomwe zimayamikiridwa chifukwa chakuchita kwake komanso kuwonongeka kwachilengedwe. Pakupanga, kusefera kothandiza ndikofunikira kuti zitsimikizire chiyero komanso kusasinthika.
Zithunzi za Great WallChithunzi cha SCYfyulutapepalaimapereka zotsatira zabwino kwambiri ndikusefedwa kwakukulu, kulimba kwamphamvu, ndi kukhazikika kokhazikika. Ndi utomoni wocheperako kuti ugwirizane bwino, ndiye chisankho chodalirika cha cellulose acetate processing m'mafakitale azakudya, azamankhwala, ndi mankhwala.
