I-Cellulose acetate iyinto eguquguqukayo enezinhlobo eziningi zezicelo. Embonini kagwayi, i-cellulose acetate tow iyinto eyinhloko yokuhlunga ugwayi ngenxa yokusebenza kwayo okuhle kakhulu kokuhlunga. Iphinde isetshenziswe embonini yamafilimu nepulasitiki ekukhiqizeni amafilimu ezithombe, ozimele bemibukiso, kanye nezibambo zamathuluzi. Ngaphezu kwalokho, i-cellulose acetate isebenza njengezinto ezibalulekile ze-membrane, kufaka phakathi i-filtrate membranes kanye nezinto ze-reverse osmosis, ngenxa yokungena kwayo okuhle nokukhetha. Ngokubola kwayo kanye nokuzivumelanisa nezimo, i-cellulose acetate iyaqhubeka nokudlala indima ebalulekile kokubili ekukhiqizeni kwendabuko kanye nezicelo zesimanje zemvelo.
Inqubo Yokuhlunga I-Cellulose Acetate
1. Ukulungiswa Kwezinto Ezingavuthiwe kanye Nokushiswa Kwe-Acetylation
Inqubo iqala ngoi-pulp yokhunii-cellulose, ehlanzwa ukuze kususwe i-lignin, i-hemicellulose, nokunye ukungcola. I-cellulose ehlanziwe ibe isisabelai-acetic acid, i-acetic anhydride, kanye ne-acetic acid.i-catalystukukhiqiza ama-ester e-cellulose acetate. Ngokulawula izinga lokufakwa esikhundleni, amazinga ahlukene njenge-diacetate noma i-triacetate angatholakala.
2. Ukulungiselela Isixazululo Sokuhlanzwa Nokuphotha
Ngemva kwe-acetylation, ingxube yokusabela iyasuswa, bese imikhiqizo elandelanayo iyasuswa. I-cellulose acetate iyagezwa, yomiswe, bese incibilikiswa ku-i-acetone noma i-acetone - izingxube zamanziukwakha isixazululo sokuphotha esifanayo. Kulesi sigaba, isixazululo siyadlulaukuhlungaukuqeda izinhlayiya namajeli angancibiliki, ukuqinisekisa ukuhambisana nokuqina.
3. Ukwakheka Kwefayibha Nokuqedwa
Isixazululo sokuphotha sicutshungulwa kusetshenziswaindlela yokuphotha eyomile, lapho ikhishwa khona ngama-spinneret bese iqina ibe yizicucu njengoba isinyibilikisi sihwamuka. Izicucu ziyaqoqwa, zelulwe, bese zenziwa zibe yintambo noma uboya obuqhubekayo. Ukwelashwa ngemva kokwelula, ukugoqa, noma ukuqeda kusetshenziswa ukuthuthukisa izakhiwo ze-fiber, okwenza zifaneleke ukusetshenziswa kuugwayiizihlungi, izindwangu, kanye nemicu ekhethekile.
Iphepha Lokuhlunga Lokuhlunga Olukhulu Lodonga
Iphepha lokuhlunga le-SCY Series
Leli phepha lokuhlunga, elinokwakheka kwe-cellulose kanye ne-cationic resin, lisebenza kahle kakhulu ekuhlungeni izixazululo ze-cellulose acetate. Linikeza amandla aphezulu okusebenza, ukugoba okuzinzile, kanye nokususwa okunokwethenjelwa kokungcola. Okuqukethwe okuphansi kwe-polyamide epoxy resin (<1.5%) kuqinisekisa ukuhambisana nokuphepha ekucubungulweni kwe-cellulose acetate, okusiza ukususa izinhlayiya ezincane, amajeli, kanye nokungcola okungancibiliki ngenkathi kugcinwa ukuzinza kwamakhemikhali kanye nokuhambisana nezindinganiso zokuphepha kokudla nemithi.
Izinzuzo
Ukusebenza Kahle Kokuhlunga Okuphezulu– Isusa ngempumelelo izinhlayiya ezincane, amajeli, kanye nokungcola okungancibiliki ezixazululweni ze-cellulose acetate.
Amandla Okusebenza Okusebenza Okuqinile– Amandla okuqhuma ≥200 kPa aqinisekisa ukuqina nokusebenza okuzinzile ngaphansi kwengcindezi.
OkuvumelanayoUkubhoboka kwe-Porosity– Ukungena komoya okulawulwayo (25–35 L/㎡·s) kunikeza amazinga okugeleza athembekile kanye nemiphumela yokuhlunga efanayo.
Isiphetho
I-cellulose acetate iyinto ebalulekile esetshenziswa ezihlungini, kumafilimu, epulasitikini, nakuma-membrane, ebaluleke kakhulu ngokusebenza kwayo kanye nokubola kwayo. Ngesikhathi sokukhiqiza, ukuhlunga okuphumelelayo kubalulekile ukuqinisekisa ubumsulwa kanye nokuvumelana.
I-Great Wall'sUchungechunge lwe-SCYisihlungiiphephainikeza imiphumela emihle kakhulu ngeukusebenza kahle kokuhlunga okuphezulu, ukuqina okuqinile, kanye nokugoba okuzinzileNjengoba inokuqukethwe okuphansi kwe-resin ukuze ivumelane kahle kakhulu, iyisinqumo esithembekile sokucubungula i-cellulose acetate embonini yokudla, yezemithi, kanye neyekhemikhali.
