Iziphumo ze-Hydroxy Ethyl Cellulose kwii-Coatings ezisekelwe emanzini

I-Hydroxyethyl cellulose (HEC) yinto eyongeziweyo eyongeziweyo kwiingubo ezisekelwe emanzini ngenxa yokukwazi ukuphucula iipropati zokugqoka. Nazi ezinye zeempembelelo ze-HEC kwiingubo ezisekelwe emanzini:

1. Ukuqina: I-HEC i-polymer e-soluble yamanzi enokwandisa kakhulu i-viscosity yeengubo ezisekelwe emanzini, okwenza kube lula ukuzisebenzisa kunye nokuphucula iimpawu zabo zokuhamba. Isiphumo sokuqina se-HEC sinokunceda ukuthintela ukuntywila kunye nokuthontsiza.
2. Ukuzinzisa: I-HEC inokuzinzisa iingubo ezisekelwe emanzini ngokuthintela ukuhlukana kwezithako kunye nokuqinisekisa ukuba zihlala zisasazwa ngokufanayo. Oku kunceda ukuphucula umgangatho jikelele kunye nokuhambelana kwengubo.
3. Ukuqulunqwa kwefilimu: I-HEC inokwenza ifilimu eqinile kwaye eguquguqukayo xa ifakwe kwiingubo ezisekelwe emanzini. Le filimu inokuphucula ukuqina kwengubo, ukunamathela, kunye nokuchasana namanzi.
4. Ukuguqulwa kwe-Rheology: I-HEC inokuguqula i-rheology yeengubo ezisekelwe emanzini ngokuphucula ukuziphatha kwabo ukucheba. Oku kuthetha ukuba i-coating iya kuba yincinci xa isetyenzisiwe, okwenza kube lula ukusasazeka, kodwa kuya kuba nzima xa kungasetyenziswanga, okuya kunceda ukunamathela kumphezulu.
5. Ukugcinwa kwamanzi: I-HEC inokunceda ukugcina amanzi kwiingubo ezisekelwe kumanzi, ezinokuthi zithintele ukuba zome ngokukhawuleza. Oku kunokuba luncedo ngakumbi kwiindawo ezishushu okanye ezomileyo, apho iingubo zinokuthi zome ngokukhawuleza kwaye zibe brittle.

Ngokubanzi, i-HEC inokuphucula ukusebenza kweengubo ezisekelwe emanzini ngokuphucula ukuqina kwazo, ukuzinzisa, ukubunjwa kwefilimu, i-rheology, kunye neendawo zokugcina amanzi. Sisongezo esisebenza ngeendlela ezininzi esinokusetyenziswa kuluhlu olubanzi lweengubo, kuquka iipeyinti, iiprimers, kunye nevanishi.
