carboxymethyl ethoxy ethyl cellulose

ICarboxymethyl ethoxy ethyl cellulose (CMEEC) yimveliso ye-cellulose ether eguquliweyo esetyenziswa kumashishini ahlukeneyo ngenxa yokuqina kwayo, ukuzinzisa, ukwenza ifilim, kunye neempawu zokugcina amanzi. Yenziwa ngokuguqula iikhemikhali zeselulosi ngokuphendula okulandelelanayo okubandakanya i-ethoxylation, i-carboxymethylation, kunye ne-ethyl esterification. Nantsi inkcazo emfutshane yeCMEEC:

Iimpawu eziphambili:

1. Ubume beMichiza: I-CMEEC ithathwe kwi-cellulose, i-polymer yendalo eyenziwe ngeeyunithi ze-glucose. Ukuguqulwa kubandakanya ukwazisa amaqela e-ethoxy (-C2H5O) kunye ne-carboxymethyl (-CH2COOH) kwi-cellulose backbone.
2. Amaqela aSebenzayo: Ubukho be-ethoxy, i-carboxymethyl, kunye namaqela e-ethyl ester anika iipropati ezizodwa kwi-CMEEC, kubandakanywa ukunyibilika emanzini kunye ne-organic solvents, amandla okwenza ifilimu, kunye nokuziphatha okuxhomekeke kwi-pH.
3. Ukunyibilika kwamanzi: I-CMEEC iqhele ukunyibilika emanzini, yenze izisombululo ze-viscous okanye i-dispersions ngokuxhomekeke kuxinzelelo kunye ne-pH yendawo. Amaqela e-carboxymethyl anegalelo kwi-solubility yamanzi ye-CMEEC.
4. Amandla okwenza iFilimu: I-CMEEC inokwenza iifilimu ezicacileyo, eziguquguqukayo xa zomisiwe, zenze ukuba zibe luncedo kwizicelo ezifana neengubo, i-adhesives, kunye neemveliso zokunyamekela.
5. I-Thickening and Rheological Properties: I-CMEEC isebenza njenge-ejenti yokuqina kwizisombululo ezinamanzi, ukwandisa i-viscosity kunye nokuphucula ukuzinza kunye nokuthungwa kwezinto ezixutywayo. Ukuziphatha kwayo okutyebileyo kunokuphenjelelwa zizinto ezinje ngoxinaniso, i-pH, ubushushu, kunye nesantya sokucheba.

Usetyenziso:

1. Iingubo kunye neePaints: I-CMEEC isetyenziswa njenge-thickener, i-binder, kunye ne-ejenti yokwenza ifilimu kwiingubo ezisekelwe emanzini kunye neepeyinti. Iphucula iipropathi zerheological, ukulinganisa, kunye nokuncamathela kweengubo ngelixa ubonelela ngokuthembeka kwefilimu kunye nokuqina.
2. I-Adhesives kunye ne-Sealants: I-CMEEC ifakwe kwi-adhesive kunye ne-sealant formulations ukuphucula i-tackiness, i-adhesion, kunye nokubambisana. Inegalelo kwi-viscosity, ukusebenza, kunye namandla okubopha izinto zokuncamathelisa kunye nezitywini.
3. IiMveliso zoNonophelo loBuqu: I-CMEEC isetyenziswa kwizinto zokuthambisa, izinto zangasese, kunye neemveliso zokhathalelo lomntu ezinje ngeekhrimu, izinto zokuthambisa, iigels, kunye nokwakheka kweenwele. Isebenza njenge-thickener, stabilizer, emulsifier, kunye ne-ejenti yokwenza ifilimu, iphucula ukuthungwa kwemveliso, ukusasazeka, kunye neempawu zokufuma.
4. Amachiza: I-CMEEC ifumana izicelo kwiifom zeyeza ezifana nokunqunyanyiswa ngomlomo, i-topical creams, kunye neefom zedosi elawulwayo. Isebenza njenge-binder, i-viscosity modifier, kunye nefilimu yangaphambili, iququzelela ukuhanjiswa kweziyobisi kunye nozinzo lwefomu yedosi.
5. Izicelo zoShishino kunye neZodwa: I-CMEEC inokusetyenziswa kwizicelo ezahlukeneyo zemizi-mveliso, kubandakanywa amalaphu, iingubo zephepha, izinto zokwakha, kunye neemveliso zezolimo, apho ukujiya kwayo, ukubopha, kunye neempawu zokwenza ifilimu ziluncedo.

I-carboxymethyl ethoxy ethyl cellulose (i-CMEEC) yimveliso ye-cellulose eguquguqukayo enezicelo ezahlukeneyo kwiingubo, i-adhesives, iimveliso zokhathalelo lomntu, amayeza, kunye namanye amacandelo oshishino, ngenxa yokunyibilika kwamanzi, amandla okwenza ifilimu, kunye neepropati ze-rheological.
