IiPropati zoMzimba zeHydroxyethyl cellulose

I-Hydroxyethyl cellulose (HEC) yipolima enyibilikayo emanzini ephuma kwi-cellulose. Isetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa. Ezinye zeempawu eziphambili ze-hydroxyethyl cellulose ziquka:

1. I-Solubility: I-HEC iyanyibilika emanzini kwaye yenza izisombululo ezicacileyo, ezibonakalayo. I-solubility ye-HEC inokwahluka ngokuxhomekeke kwizinto ezifana nezinga lokutshintshwa (i-DS) yamaqela e-hydroxyethyl kunye nobunzima be-molecular of polymer.
2. I-Viscosity: I-HEC ibonisa i-viscosity ephezulu kwisisombululo, enokulungiswa ngezinto ezahlukeneyo ezifana nokugxininiswa kwe-polymer, ubushushu, kunye nesantya sokucheba. Izisombululo ze-HEC zihlala zisetyenziswa njengeejenti ezityebisayo kuluhlu olubanzi lwezicelo, kubandakanya iipeyinti, izinto zokuncamathelisa, kunye neemveliso zokhathalelo lomntu.
3. Amandla okwenza iFilimu: I-HEC inamandla okwenza iifilimu eziguquguqukayo kunye nezidibeneyo xa zomile. Le propathi isetyenziswa kwizicelo ezinje ngokugquma iipilisi kunye neecapsules kumayeza, nakwizinto zokuthambisa kunye neemveliso zokhathalelo lomntu.
4. Ukugcinwa kwamanzi: I-HEC ineempawu ezigqwesileyo zokugcina amanzi, iyenza ibe yipolymer esebenzayo enyibilikayo emanzini ukuze isetyenziswe kwizinto zokwakha ezifana nodaka, iigrouts, kunye neerenders. Inceda ukuthintela ukulahleka kwamanzi ngokukhawuleza ngexesha lokuxuba kunye nokusetyenziswa, ukuphucula ukusebenza kunye nokubambelela.
5. Ukuzinza kwe-Thermal: I-HEC ibonisa ukuzinza okulungileyo kwe-thermal, igcina iipropati zayo kwiintlobo ezininzi zamaqondo okushisa. Iyakwazi ukumelana namaqondo obushushu aqubisana nawo kumashishini ahlukeneyo ngaphandle kokuthotywa okubalulekileyo.
6. I-pH Ukuzinza: I-HEC izinzile phezu koluhlu olubanzi lwe-pH, okwenza ukuba ilungele ukusetyenziswa kwimixube ene-acidic, i-neutral, okanye i-alkaline. Le propati ivumela ukusetyenziswa kwayo kwiintlobo ezahlukeneyo zezicelo ngaphandle kokukhathazeka malunga nokuthotywa kwe-pH.
7. Ukuhambelana: I-HEC iyahambelana noluhlu olubanzi lwezinye izithako, kubandakanywa neetyuwa, i-acids, kunye ne-solvents eziphilayo. Oku kuhambelana kuvumela ukuqulunqwa kweenkqubo eziyinkimbinkimbi ezinezakhiwo ezilungiselelwe kumashishini afana namayeza, ukunakekelwa komntu kunye nokwakhiwa.
8. I-Biodegradability: I-HEC ithathwe kwimithombo ehlaziyekayo efana nentlaka yeplanga kunye nomqhaphu, iyenza ikwazi ukubola kwaye ihambelane nokusingqongileyo. Ihlala ikhethwa ngaphezu kweepolima zokwenziwa kwizicelo apho uzinzo luyinkxalabo.

iimpawu ezibonakalayo ze-hydroxyethyl cellulose (HEC) zenza ukuba ibe yongezelelo oluxabisekileyo kumashishini ahlukeneyo, apho igalelo ekusebenzeni, ukuzinza, kunye nokusebenza koluhlu olubanzi lweemveliso kunye nokuqulunqwa.
