I-Cellulose acetate sisixhobo esinokusetyenziswa ngeendlela ezahlukeneyo. Kwishishini lecuba, i-cellulose acetate tow yeyona nto iphambili yokucoca icuba ngenxa yokusebenza kwayo okuhle kakhulu kokuhluza. Ikwasetyenziswa kwishishini lefilimu kunye neplastiki ekwenzeni iifilimu zeefoto, iifreyimu zemiboniso, kunye neziphatho zezixhobo. Ukongeza, i-cellulose acetate isebenza njengesixhobo esibalulekileyo kwiimembrane, kubandakanya iimembrane zokuhluza kunye nezinto ezibuyisela umva i-osmosis, ngenxa yokungena kwayo kakuhle kunye nokukhetha kwayo. Ngenxa yokubola kwayo kunye nokuzivumelanisa nezimo, i-cellulose acetate iyaqhubeka nokudlala indima ebalulekileyo kwimveliso yendabuko kunye nokusetyenziswa kwendalo yanamhlanje.
Inkqubo yokucoca i-Cellulose Acetate
1. Ukulungiswa kwezinto eziluhlaza kunye ne-Acetylation
Inkqubo iqala ngointlama yomthii-cellulose, ecocwa ukuze kususwe i-lignin, i-hemicellulose, kunye nezinye izinto ezingcolileyo. I-cellulose ecociweyo emva koko iphendulwai-acetic acid, i-acetic anhydride, kunye ne-acetic acidisikhuthaziukuvelisa ii-esters ze-cellulose acetate. Ngokulawula izinga lokutshintshwa, iiklasi ezahlukeneyo ezifana ne-diacetate okanye i-triacetate zinokufunyanwa.
2. Ukulungiswa kwesisombululo sokucocwa nokujikeleziswa
Emva kwe-acetylation, umxube we-reaction uyasuswa, kwaye iimveliso ezishiyekileyo ziyasuswa. I-cellulose acetate iyahlanjwa, yomiswe, kwaye inyibilikiswe kwi-imixube ye-acetone okanye i-acetone-amanziukwenza isisombululo esijikelezayo esifanayo. Kweli nqanaba, isisombululo siyadlulaukuhluzaukuphelisa amasuntswana kunye neejeli ezinganyibilikiyo, ukuqinisekisa ukuhambelana kunye nozinzo.
3. Ukwenziwa kweFiber kunye nokuGqitywa kwayo
Isisombululo sokujikelezisa sicutshungulwa kusetyenziswaindlela yokusonta eyomileyo, apho ikhutshwa khona ngee-spinnerets ize iqine ibe zii-filaments njengoko isinyibilikisi siphuma. Ii-filaments ziyaqokelelwa, zolulwe, kwaye zenziwe zibe yintambo eqhubekayo okanye intambo. Emva konyango olufana nokuzolula, ukukrwela, okanye ukugqiba kusetyenziswa ukuphucula iipropati zefayibha, nto leyo eyenza ukuba zifaneleke ukusetyenziswa kwiicubaizihluzi, amalaphu, kunye neefayibha ezikhethekileyo.
Iphepha lesihluzi seGreat Wall Filtration
Iphepha lesihluzi se-SCY Series
Eli phepha lesihluzo, elinokwakheka kwe-cellulose kunye ne-cationic resin, lisebenza kakuhle kakhulu ekuhluzeni izisombululo ze-cellulose acetate. Linika amandla aphezulu oomatshini, i-porosity ezinzileyo, kunye nokususwa okunokuthenjwa kokungcola. Umxholo ophantsi we-polyamide epoxy resin (<1.5%) uqinisekisa ukuhambelana kunye nokhuseleko ekucutshungulweni kwe-cellulose acetate, ukunceda ukususa amasuntswana amancinci, iijeli, kunye nokungcola okunganyibilikiyo ngelixa kugcinwa uzinzo lweekhemikhali kunye nokuthobela imigangatho yokhuseleko lokutya kunye namayeza.
Iingenelo
Ukusebenza kakuhle kokuhluza okuphezulu– Isusa ngokufanelekileyo amasuntswana amancinci, iijeli, kunye nokungcola okunganyibilikiyo kwizisombululo ze-cellulose acetate.
Amandla Oomatshini Aqinileyo– Amandla okuqhuma ≥200 kPa aqinisekisa ukuqina nokusebenza okuzinzileyo phantsi koxinzelelo.
IyahambelanaUkugquma– Ukungena komoya olawulwayo (25–35 L/㎡·s) kubonelela ngamanani okuhamba okuthembekileyo kunye neziphumo zokuhluza ezifanayo.
Isiphelo
I-cellulose acetate yinto ephambili esetyenziswa kwiifilitha, iifilimu, iiplastiki, kunye neemembrane, exatyiswa ngenxa yokusebenza kwayo kunye nokubola kwayo. Ngexesha lokuveliswa, ukuhluzwa okusebenzayo kubalulekile ukuqinisekisa ubunyulu kunye nokuhambelana.
IGreat Wall'sUthotho lwe-SCYisihluzoiphephainika iziphumo ezibalaseleyo ngeukusebenza kakuhle kokuhluza, ukuqina okuqinileyo, kunye nokuvuleka okuzinzileyoNgenxa yomxholo ophantsi we-resin ukuze ihambelane kakuhle, lukhetho oluthembekileyo lokucubungula i-cellulose acetate kumashishini okutya, amayeza, kunye neekhemikhali.
