Ethyl Cellulose

I-Ethyl cellulose iphuma kwi-cellulose, i-polymer yendalo efumaneka kwizityalo. Iveliswa ngokusabela kwe-cellulose kunye ne-ethyl chloride phambi kwe-catalyst. I-Ethyl cellulose isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa kunye nokuguquguquka. Nazi ezinye iimpawu eziphambili kunye nokusetyenziswa kwe-ethyl cellulose:

1. I-Insolubility emanzini: I-Ethyl cellulose ayinyibiliki emanzini, eyenza ukuba ifaneleke kwizicelo apho ukuxhatshazwa kwamanzi kuyadingeka. Le propati iphinda ivumele ukusetyenziswa kwayo njengengubo ekhuselayo kumachiza kunye njengento yokuthintela ekupakisheni kokutya.
2. I-Solubility kwi-Organic Solvents: I-Ethyl cellulose iyanyibilika kuluhlu olubanzi lwezinyibilikisi ze-organic, kuquka i-ethanol, i-acetone, kunye ne-chloroform. Oku kunyibilika kwenza kube lula ukusetyenzwa kunye nokwenza iimveliso ezahlukeneyo, ezinje ngeengubo, iifilimu, kunye nee-inki.
3. Amandla okwenza iFilimu: I-Ethyl cellulose inamandla okwenza iifilimu eziguquguqukayo kunye nezizinzileyo xa zomile. Le propati isetyenziswe kwizicelo ezifana neengubo zethebhulethi kwi-pharmaceuticals, apho inikeza umaleko okhuselayo wezithako ezisebenzayo.
4. I-Thermoplasticity: I-Ethyl cellulose ibonisa ukuziphatha kwe-thermoplastic, oku kuthetha ukuba inokuthanjiswa kwaye ibunjwe xa ishushu kwaye yomelela xa ipholisa. Le propati yenza ukuba ilungele ukusetyenziswa kwi-adhesives e-hot-melt kunye neeplastiki ezinokubunjwa.
5. Ukungangeni kweMichiza: I-cellulose ye-Ethyl ayisebenzi ngokwekhemikhali kwaye iyamelana ne-asidi, i-alkali, kunye nezona zinyibilikisi zininzi. Le propati yenza ukuba ilungele ukusetyenziswa ekuqulunqweni apho ukuzinza kunye nokuhambelana nezinye izithako kubalulekile.
6. I-Biocompatibility: I-Ethyl cellulose ithathwa njengekhuselekile (GRAS) ukuba isetyenziswe kumayeza, ukutya, kunye neemveliso zokuthambisa. Ayinatyhefu kwaye ayifaki umngcipheko wemiphumo emibi xa isetyenziswe njengoko ijoliswe kuyo.
7. Ukukhutshwa okuLawulwayo: I-Ethyl cellulose isoloko isetyenziselwa ukuqulunqa amayeza ukulawula ukukhutshwa kwezithako ezisebenzayo. Ngokulungelelanisa ubukhulu be-ethyl cellulose yokwambathisa kwiipilisi okanye iipelisi, izinga lokukhutshwa kweziyobisi linokuguqulwa ukuze kuphunyezwe iiprofayili zokukhululwa ezongeziweyo okanye eziqhubekayo.
8. I-Binder kunye ne-Thickener: I-cellulose ye-Ethyl isetyenziswa njenge-binder kunye ne-thickener kwizicelo ezahlukeneyo, kubandakanywa i-inki, i-coatings, kunye ne-adhesives. Iphucula iimpawu ze-rheological zokuqulunqa kwaye inceda ukufezekisa ukuhambelana okufunwayo kunye ne-viscosity.

I-ethyl cellulose yipolymer eguquguqukayo enoluhlu olubanzi lwezicelo kumashishini afana namayeza, ukutya, izinto zokuthambisa, izinto zokuthambisa, kunye nokuncamathelisa. Inhlanganisela yayo ekhethekileyo yeepropati yenza ukuba ibe yinto ebalulekileyo kwiindlela ezininzi zokuqulunqa, apho igalelo ekuzinzeni, ekusebenzeni, nasekusebenzeni.
