Folasaga ile ethyl cellulose
O le Ethylcellulose o se mea e maua mai i le cellulose, o se polymer masani e maua i totonu o puipui o laau.E gaosia e ala i le ethylation tali ole cellulose ma le ethyl chloride poʻo le ethylene oxide.O lenei suiga e tuʻuina atu ai mea faʻapitoa mea faʻapitoa, faʻapitoa mo faʻaoga eseese, aemaise lava o se faʻapipiʻi i pisinisi eseese.
Uiga o le ethylcellulose
Fa'atonuga Vailaau: Ethylcellulose e aofia ai iunite toe fai o le anhydroglucose e feso'ota'i i fusi β(1→4) glycosidic.O le ethylation o le cellulose e sui ai nisi vaega hydroxyl (-OH) ma vaega ethoxy (-OCH2CH3).
Solubility: O le Ethylcellulose e le mafai ona solu i totonu o le vai, ae mafai ona solu i solu faʻaletino e pei ole ethanol, acetone, toluene, ma chloroform.O lenei meatotino e talafeagai mo talosaga e manaʻomia ai le vai.
Mafai e fai ata tifaga: E mafai e le Ethyl cellulose ona fausia se ata fe'avea'i ma manino pe a uma ona fa'amavae i totonu o se solu fa'aletino talafeagai.O nei ata tifaga o loʻo i ai le malosi faʻainisinia lelei ma mea faʻalavelave.
Thermoplasticity: Ethylcellulose o loʻo faʻaalia amioga vevela, faʻafaigofie ona faʻaogaina auala e pei o le extrusion, tui tui, ma le faʻapipiʻiina.
Fegalegaleaiga: Ethylcellulose e fetaui ma le tele o isi polymers, plasticizers ma faʻaopoopoga, e faʻaogaina ai le faʻaogaina i le tele o faʻasologa.
Fa'aaogāina ole ethyl cellulose e fa'apipi'i
1. Alamanuia tau vailaau
I vailaʻau vailaʻau, ethylcellulose galue o se fusi i le gaosiga o laulau.E fesoasoani e fusifusia ai le vailaʻau malosi (API) ma mea faʻaoga faʻatasi, faʻamautinoa le saʻo ma le tutusa o le laulau.E le gata i lea, o le ethylcellulose o loʻo faʻaaogaina foʻi i faʻasalalauga faʻatonutonu-faʻasaʻo e manaʻomia ai le faʻamalolo tumau o vailaʻau.
2. Alamanuia tau taumafa
O le Ethylcellulose o loʻo faʻaaogaina e fai ma fusi, mafiafia, ma faʻamautu i meaʻai.E faʻaaogaina i le ufiufi o fualaau 'aina, fualaau faisua ma mea faʻafefete e faʻaleleia ai o latou foliga vaaia ma le ola.O le ufiufi o le Ethylcellulose e maua ai se pa puipui mai le susu, kasa ma mea leaga.
3. Pa'u ma vaitusi
I totonu o le paluga ma le vaitusi, e faʻaaogaina le ethylcellulose e fai ma fusi i vali, varnishes, varnishes, ma lomitusi vaitusi faʻavae.E tuʻuina atu i nei coatings adhesion, fetuutuunai ma vai faʻafefe, faʻaleleia atili ai a latou faʻatinoga ma le tumau.
4. Mea teuteu
O le Ethylcellulose o loʻo faʻaaogaina e avea o se mafiafia ma faʻamautu i mea teuteu e pei o kulimi, lotions ma mea e teu ai lauulu.E fesoasoani i le ausiaina o le mea e manaʻomia, tutusa ma le viscosity i cosmetic formulations.
5. Talosaga fa'apisinisi
I mea tau alamanuia, o le ethylcellulose o loʻo faʻaaogaina e fai ma fusi i le gaosiga o mea sima, abrasives ma composites.E fesoasoani i le fausiaina o tino lanu meamata ma pulea le faʻaogaina o mea faʻapitoa o paʻu ma slurries.
Fa'asologa o le ethylcellulose
O le tu'ufa'atasiga o le ethylcellulose e aofia ai le tali atu o le cellulose ma se vaila'au ethylating i lalo o tulaga pulea.Ole tali ole ethylation e masani ona faia ile i ai o se faʻamalosi e pei ole acid poʻo se faʻavae e faʻaleleia ai le suia o vaega hydroxyl ma vaega ethoxy.O le tikeri o le suitulaga (DS) o loʻo faʻatusalia ai le averesi numera o vaega ethoxy i le kulukose iunite i le filifili polymer ma e mafai ona faʻatonutonuina e ala i le fetuutuunai o faʻasologa o tali e pei o le taimi faʻaalia, vevela, ma le molar ratio o reactants.
Tulaga lelei o le ethylcellulose e fai ma fusi
Versatility: Ethylcellulose faʻaalia le agavaʻa e tusa ai ma le solubility, fesoʻotaʻiga ma le mafai ona faia ata tifaga, faʻafaigofie mo le tele o faʻaoga i totonu o alamanuia.
Suavai Tetee: Ethylcellulose e le mafai ona solu i totonu o le vai, ma avea o se filifiliga sili ona lelei mo faʻatulagaga e manaʻomia ai le faʻafefe o le vai, e pei o paʻu, vali, ma vailaʻau faʻamalolo faʻatonutonu.
Thermoplasticity: O le amio vevela o le ethylcellulose e mafai ai ona faʻafaigofie le faʻaogaina o metotia faʻaleaganuʻu masani, e mafai ai ona taugofie le gaosiga o gaosiga.
Biocompatibility: Ethylcellulose e masani ona aloaia o se saogalemu (GRAS) e lala sooupu faʻatonutonu mo le faʻaogaina i meaʻai ma vailaʻau, faʻamautinoa lona biocompatibility ma le saogalemu o tagata faʻatau.
Fa'asa'o fa'atonuina: E fa'aaogaina lautele le Ethylcellulose i fale talavai e fa'atutu ai fomu fa'amatu'u fa'atonu e tu'uina atu ai le fa'atonuga tonu o le fua fa'asa'o o vaila'au.
Ethylcellulose o loʻo avea o se faʻapipiʻi multifunctional ma le tele o faʻaoga i vailaʻau, meaʻai, paʻu, mea teuteu ma fale gaosi oloa.O ona uiga tulaga ese, e aofia ai le solubility, ata-fausia le gafatia ma le fetaui, e avea o se mea e manaʻomia i le tele o faʻatulagaga.O le tu'ufa'atasiga o le ethylcellulose e maua ile ethylating cellulose i lalo ole tulaga fa'atonutonu, ma maua ai mea e fa'atatau i mea totino talafeagai mo fa'aoga fa'apitoa.Faatasi ai ma lona tetee atu i le vai, thermoplasticity ma faʻasaʻo faʻatonutonu, ethylcellulose o loʻo faʻaauau pea ona faia se sao taua i le faʻaleleia o le faʻatinoga ma le faʻatinoga o oloa i le tele o alamanuia.
