Iindlela zokuchithwa kunye nokusetyenziswa okuphambili kwe-ethylcellulose

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, ziyakukhawulezisa ukunyibilika.

Iqondo lobushushu: Ukunyuka kwamaqondo obushushu kwandisa izinga lokunyibilika kuba kunika amandla ongezelelweyo kwintsebenziswano ye-polymer-solvent. Nangona kunjalo, ubushushu obugqithisileyo bunokubangela ukuthotywa.

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:
