Amanqanaba ahlukeneyo e-ethyl cellulose (EC)

I-Ethyl cellulose yipolymer eguquguqukayo enoluhlu olubanzi lwezicelo, ukusuka kumayeza ukuya kwiingubo zokwaleka ukuya kwezongezo zokutya. Iimpawu zayo zinokwahluka kakhulu ngokuxhomekeke kwibakala layo, elichongwa zizinto ezinjengobunzima bemolekyuli, iqondo lokutshintshwa, kunye nokusabalalisa ubungakanani besuntswana.

1.Intshayelelo ye-Ethyl Cellulose

I-Ethyl cellulose iphuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo. Yenziwa nge-ethylation ye-cellulose, apho amaqela e-hydroxyl kumqolo we-cellulose athatyathwa ngamaqela e-ethyl. Olu hlengahlengiso lunika iipropathi ezikhethekileyo kwi-ethyl cellulose, kubandakanywa isakhono esihle sokwenza ifilimu, ukumelana neekhemikhali, kunye nokuzinza kwe-thermal.

2.AmaBanga obunzima beMolekyuli ePhantsi ukuya koPhakathi:

La mabanga anemilinganiselo yeemolekyuli ukusuka kwi-30,000 ukuya kwi-100,000 g/mol.
Zibonakaliswa yi-viscosity yazo ephantsi kunye namazinga okutshatyalaliswa ngokukhawuleza xa kuthelekiswa namabakala aphezulu obunzima be-molecular.
Usetyenziso:
Iingubo: Isetyenziswa njengezibophelelo kwiipilisi, iipilisi, kunye neegranules kumachiza.
Ukukhutshwa okuLawulwayo: Kuqeshwe kwiinkqubo zokuhanjiswa kweziyobisi ezilawulwayo apho ukupheliswa ngokukhawuleza kunqweneleka.
Iinki: Zisetyenziswa njengezityebi kunye neearhente zokubumba iifilim kwii-inki zokushicilela.

3.AmaBanga aphezulu obunzima beMolekyuli:

La mabanga anobunzima beemolekyuli obudlula i-100,000 g/mol.
Zibonisa i-viscosity ephezulu kunye namazinga okuchithwa okucothayo, okwenza ukuba zilungele ukukhutshwa okuzinzileyo.
Usetyenziso:
Ukukhutshwa okuZinzileyo: Kukulungele ukuqulunqa iifom zedosi yokukhutshwa okuzinzileyo kumayeza, ukubonelela ngokukhululwa kwechiza ixesha elide.
I-Encapsulation: Isetyenziswa kwiitekhnoloji ze-encapsulation zokukhutshwa okulawulwayo kweencasa, iziqholo, kunye nezithako ezisebenzayo.
Iifilimu zoMthintelo: Zisetyenziswa njengezinto zokugquma izithintelo kwipakethe yokutya ukuze kuphuculwe ubomi beshelufu kunye nokuthintela ukungena kokufuma.

4.Idigri yoTshintsho (DS) ezahlukeneyo:

I-Ethyl cellulose ingaba needigri ezahlukeneyo zokutshintshwa, ebonisa inani eliqhelekileyo lamaqela e-ethyl ngeyunithi ye-anhydroglucose kwikhonkco leselulosi.
Amabanga anamaxabiso aphezulu e-DS anamaqela amaninzi e-ethyl kwiyunithi nganye yeseli, okukhokelela ekunyukeni kwe-hydrophobicity kunye nokuncipha kokunyibilika kwamanzi.
Usetyenziso:
Ukuchasana naManzi: Amanqanaba aphezulu e-DS asetyenziswa kwiingubo kunye neefilimu apho ukuxhathisa kwamanzi kubaluleke kakhulu, njengokugquma umqobo wokukhusela iipilisi kunye neepilisi.
I-Solvent Resistance: Ifanelekile kwizicelo ezifuna ukuchasana nezinyibilikisi zendalo, njenge-inki kunye neengubo zokuprinta kunye nokupakishwa.

5.Iizahluko zobungakanani beParticle:

I-cellulose ye-Ethyl ifumaneka kwiintlobo ezahlukeneyo zokusabalalisa ubungakanani be-particle, ukusuka kwi-micrometer-size particles ukuya kwi-nanometer-size powders.
Ubungakanani bamasuntswana alungileyo anika izibonelelo ezinjengokuphucuka kwe-dispersibility, iingubo ezigudileyo, kunye nokuhambelana okuphuculweyo kunye nezinye izithako.

6.Izicelo:

I-Nanoencapsulation: I-Nanoscale ethyl cellulose particles isetyenziswe kwi-nanomedicine yokuhanjiswa kweziyobisi, ivumela ukuhanjiswa okujoliswe kuyo kunye nokuphucula ukusebenza konyango.
I-Nano Coatings: I-ethyl cellulose powders emihle iqeshwe kwiingubo ezikhethekileyo, ezifana nezithintelo zokuthintela i-electronics flexible kunye nezixhobo ze-biomedical.

I-Ethyl cellulose yipolymer eguquguqukayo enemisebenzi eyahlukeneyo kuwo wonke amashishini, kwaye amabanga ayo ahlukeneyo abonelela ngeempawu ezilungiselelwe ukuhlangabezana neemfuno ezithile zokuyilwa. Ukusuka kumabakala asezantsi ukuya kubunzima obuphezulu bemolekyuli ukuya kwiiyantlukwano ezisekelwe kwiqondo lokutshintshwa kunye nokusabalalisa ubungakanani besuntswana, i-ethyl cellulose ibonelela ngoluhlu olubanzi lweendlela zokukhetha abaqulunqi abafuna izisombululo ekuhanjisweni kweziyobisi, iingubo, i-encapsulation, nangaphezulu. Ukuqonda iimpawu zebanga ngalinye kubalulekile ekuphuculeni umgangatho womsebenzi nokufikelela kwiziphumo ezinqwenelekayo kwizicelo ezahlukeneyo.
