I-Ethylcellulose i-polymer esebenzayo ephuma kwi-cellulose ngokusungulwa kwamaqela e-ethyl.Olu hlengahlengiso lunika iipropathi zepolymer ezizodwa, ziyenza ilungele usetyenziso oluhlukeneyo lwemizi-mveliso.Inkalo ebalulekileyo yokusebenzisa i-ethylcellulose kwiinkalo ezahlukeneyo kukuqonda ukuziphatha kwayo kokuchithwa njengoko kuchaphazela inkqubo kunye nokusetyenziswa kwayo.
Indlela yokuphelisa i-ethylcellulose:
Iimpawu zokunyibilika:
Ngenxa yobume be-hydrophobic ye-ethyl substituent, i-ethylcellulose inyibilika kancinane emanzini.Nangona kunjalo, ibonakalisa ukunyibilika kuluhlu olubanzi lwezinyibilikisi eziphilayo, okwenza ukuba ifaneleke ngokukodwa kwizicelo apho ukuxhathisa kwamanzi kubaluleke kakhulu.Izinyibilikisi eziqhelekileyo ze-ethylcellulose ziquka i-ethanol, i-ethyl acetate, i-methylene chloride, kunye ne-toluene.Inkqubo yokutshatyalaliswa ibandakanya ukuphulwa kwamandla e-intermolecular ngaphakathi kwepolymer, ukuvumela i-solvent ukuba ingene kwaye isasaze iintambo ze-polymer.
Izinto ezichaphazela ukupheliswa:
Izinto ezininzi ezichaphazela ukuchithwa kwe-ethylcellulose:
Ukukhetha isinyibilikisi: Ukukhetha isinyibilikisi kudlala indima ebalulekileyo kwinkqubo yonyibiliko.Izinyibilikisi ezinobudlelwane obuphezulu be-ethylcellulose, njenge-ethyl acetate, ziya kukhawuleza ukutshatyalaliswa.
Iqondo lobushushu: Ukunyuka kwamaqondo obushushu kwandisa izinga lokunyibilika kuba kunika amandla ongezelelweyo kwintsebenziswano ye-polymer-solvent.Nangona kunjalo, ubushushu obugqithisileyo bunokubangela ukuhla.
Ubungakanani bamasuntswana epolymer: Ubungakanani besuntswana elincinci libonelela ngommandla omkhulu wokudibana kwe-solvent, okukhokelela ekunyibilikeni ngokukhawuleza.Ukusila okufanelekileyo okanye iindlela zokunciphisa ubungakanani besuntswana zingasetyenziselwa ukulungelelanisa ukunyibilika.
IBanga lePolymer: Ibakala le-ethylcellulose lichongwa ngumxholo we-ethoxy kunye nobunzima be-molecular, obuchaphazela ukunyibilika kwayo.Umxholo ophezulu we-ethoxy ngokubanzi wongeza ukunyibilika.
Ukuvuselela okanye ukuphazamiseka: Ukuvuselela oomatshini okanye ukuphazamiseka kunceda ukungena kwe-solvent kwi-matrix ye-polymer kwaye kukhawulezise inkqubo yokutshatyalaliswa.
Iindlela ezixhaphakileyo zokuphelisa:
Zininzi iindlela ezinokusetyenziselwa ukunyibilikisa i-ethylcellulose:
Ukuxutywa kwesisombululo: Oku kubandakanya ukuxuba i-ethylcellulose kunye ne-solvent efanelekileyo kunye nokuvuselela umxube de uchithe ngokupheleleyo.Le ndlela isetyenziswa ngokuqhelekileyo kwizicwangciso zebhubhoratri.
I-Spray Coating: Kwizicelo zemizi-mveliso, izisombululo ze-ethylcellulose zihlala zilungiselelwe inkqubo yokutshiza.I-solvent iyaphuphuma, ishiya ifilimu encinci ye-ethylcellulose kwi-substrate.
I-Hot melt extrusion: Obu buchule bubandakanya ukufudumeza umxube we-ethylcellulose kunye nezinye izinto kwimo etyhidiweyo kwaye emva koko uwukhuphe ngokufa.Emva kokupholisa, i-ethylcellulose iyaqina.
Ukuqonda iimpawu zokuchithwa kunye neendlela zibalulekile ukulungelelanisa i-ethylcellulose kwizicelo ezithile.
Ukusetyenziswa okuphambili kwe-ethyl cellulose:
Umzi mveliso wamachiza:
