Cellulose acetate o se mea faʻapitoa ma le tele o faʻaoga. I totonu o pisinisi tapaa, o le cellulose acetate tow o le mea muamua lea mo faamama sikaleti ona o lona faʻaogaina lelei o le faʻaogaina. E fa'aaogaina fo'i i fale tifaga ma palasitika mo le gaosiga o ata, fa'avaa fa'aaliga, ma au mea faigaluega. E le gata i lea, o le cellulose acetate o loʻo avea ma mea autu mo paʻu, e aofia ai le faʻamamaina o masini ma faʻaliliuina elemene osmosis, faʻafetai i lona faʻaogaina lelei ma le filifilia. Faatasi ai ma lona biodegradability ma fetuutuunai, cellulose acetate o loʻo faʻaauau pea ona faia se sao taua i le gaosiga masani ma le siosiomaga faʻaonaponei.
Cellulose Acetate Filtration Process
1. Sauniuniga o Mea Mata'utia & Acetylation
O le faagasologa e amata ifasi laupapaselulosa, lea e faʻamamaina e aveese ai le lignin, hemicellulose, ma isi mea leaga. Ona tali atu lea o le cellulose fa'amamainaacetic acid, acetic anhydride, ma le afa'atosinae gaosia ai esters acetate cellulose. E ala i le puleaina o le tikeri o le suitulaga, e mafai ona maua ni togi eseese e pei o le diacetate poʻo le triacetate.
2. Fa'amamāina & Fa'alilo Sauniuniga Fofo
A maeʻa le acetylation, o le faʻafefiloi o tali e faʻaleagaina, ma faʻaumatia mea e maua mai ai. O le cellulose acetate e fufulu, faʻamago, ma faʻamavae i totonuacetone po'o acetone-vai fa'afefiloie fai ai se vaifofo vili tutusa. I lenei laʻasaga, o loʻo i ai le fofofaamamainae faʻaumatia ai vaega e leʻi faʻafefeteina ma gels, faʻamautinoa le tumau ma le mautu.
3. Fiber Formation & Finishing
O le vaifofo vili e fa'aogaina e fa'aaoga ai leauala vili mago, lea e fa'aosoina e ala i spinnerets ma fa'amausali i filaments a'o fa'asao le solvent. O filaments e aoina, faʻaloloa, ma faʻatupuina e avea ma toso faʻaauau poʻo se vulu. Togafitiga mulimuli e pei o le fa'aloaloa, crimping, po'o le fa'amae'aina e fa'aoga e fa'aleleia atili ai le alava, ma fa'afaigofie ai mo fa'aoga i totonu.sikaletifiliga, 'ie, ma alava fa'apitoa.
Pepa Filter Filtration Pa Tele
SCY Fa'asologa pepa faamama
O lenei pepa faamama, faatasi ai ma lona cellulose ma cationic resin composition, e sili ona aoga mo le faamamaina o vaifofo acetate cellulose. E maua ai le malosi fa'ainisinia maualuga, fa'amautu porosity, ma le fa'atuatuaina le fa'aesea o mea leaga. O le maualalo o le polyamide epoxy resin content (<1.5%) faʻamautinoa le fesoʻotaʻiga ma le saogalemu i le gaosiga o le cellulose acetate, fesoasoani e aveese vaega lelei, gels, ma mea e le mafai ona faʻaogaina aʻo tausia le faʻamautuina o vailaʻau ma le tausisia o meaʻai ma vailaʻau saogalemu.
Tulaga lelei
Lelei Fa'amama maualuga– Aveese lelei vaega laiti, gels, ma le le mafai ona solu le mama mai vaifofo cellulose acetate.
Malosi Fa'ainisinia Malosi- Malosi malosi ≥200 kPa faʻamautinoa le tumau ma le faʻatinoina o le faʻatinoga i lalo o le mamafa.
Fa'atasiPorosity– Pulea ea permeability (25–35 L/㎡·s) e maua ai fua faatatau tafe faatuatuaina ma filtration taunuuga tutusa.
Fa'ai'uga
O le cellulose acetate o se mea autu e faʻaaogaina i filiga, ata tifaga, palasitika, ma membranes, faʻatauina mo lona faʻatinoga ma le biodegradability. I le taimi o le gaosiga, e manaʻomia le faʻamamaina lelei e faʻamautinoa ai le mama ma le tumau.
Pa TeleSCY Fa'asologafaamamapepatuuina atu i'uga mata'ina mamaualuga filtration lelei, malosi tumau, ma mautu porosity. Faʻatasi ai ma le maualalo o le resin content mo le fetaui lelei, o le filifiliga faʻatuatuaina mo le gaosiga o le cellulose acetate i meaʻai, vailaʻau, ma vailaʻau faʻamalosi.
