Ukuqaliswa kwe-Hydroxyethyl Cellulose
I-Hydroxyethyl Cellulose (HEC) i-non-ionic, i-polymer e-soluble yamanzi ephuma kwi-cellulose, i-polymer yendalo efumaneka kwizityalo. I-HEC isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa kunye nokusetyenziswa okuguquguqukayo. Nantsi intshayelelo yeHydroxyethyl Cellulose:
1. Ulwakhiwo lweMichiza:
- I-HEC yi-ether ye-cellulose eguqulwe ngamaqela e-hydroxyethyl. Iveliswa ngokuphendula i-cellulose kunye ne-ethylene oxide phantsi kweemeko ezilawulwayo. Iqondo lokutshintshwa (DS) lwamaqela e-hydroxyethyl kwi-cellulose backbone imisela iipropati kunye nokusebenza kwe-HEC.
2. IiPropati zoMzi:
- I-HEC imhlophe ukuya kumhlophe-mhlophe, ayinavumba, kwaye ingenancasa okanye igranule. I-soluble emanzini kwaye yenza izisombululo ezicacileyo, ezibonakalayo kunye ne-rheology ye-pseudoplastic. I-viscosity yezisombululo ze-HEC zinokuhlengahlengiswa ngokutshintsha i-polymer concentration, i-degree of substitution, kunye ne-molecular weight.
3. IiPropati zeRheological:
- I-HEC ibonisa i-thickening egqwesileyo kunye neempawu ze-rheological, iyenza i-thickener esebenzayo, i-stabilizer, kunye nefilimu-yangaphambili kwizicelo ezahlukeneyo. Ibonelela ngokuziphatha kwe-pseudoplastic, oku kuthetha ukuba i-viscosity yayo iyancipha ngesantya sokucheba, ivumela ukusetyenziswa okulula kunye nokusabalalisa.
4. Ugcino lwamanzi:
- I-HEC inomthamo ophezulu wokugcinwa kwamanzi, ukwandisa ixesha lenkqubo yokuxutywa kwe-hydration kwiifom ezifana nezixhobo ze-cementitious, i-adhesives, kunye neengubo. Iphucula ukusebenza, ukubambelela, kunye nokubeka ixesha ngokugcina amanqanaba okufuma kunye nokuthintela ukulahleka kwamanzi ngokukhawuleza.
5. UkuNcitshiswa kweTension yoMphezulu:
- I-HEC inciphisa ukunyanzeliswa komphezulu wokuqulunqwa kwamanzi, ukuphucula ukumanzisa, ukusabalalisa, kunye nokuhambelana nezinye izongezo kunye ne-substrates. Le propati iphakamisa ukusebenza kunye nokuzinza kokuqulunqwa, ngokukodwa kwi-emulsions kunye nokumiswa.
6. Uzinzo kunye nokuhambelana:
- I-HEC i-inert yekhemikhali kwaye iyahambelana noluhlu olubanzi lwezinye izithako, kuquka i-surfactants, i-salts, i-acids, kunye ne-alkalis. Ihlala izinzile kuluhlu olubanzi lwe-pH kunye nobushushu, iqinisekisa ukusebenza okufanayo kwiindlela ezahlukeneyo kunye neenkqubo.
7. Ukwenziwa kwefilimu:
- I-HEC yenza iifilimu eziguquguqukayo, ezicacileyo xa zomisiwe, zibonelela ngeempawu zomqobo kunye nokunamathela kwiindawo. Isetyenziswe njenge-ejenti yokwenza ifilimu kwiingubo, i-adhesives, imveliso yokunyamekela komntu, kunye nokuqulunqwa kwamayeza, ukuphucula ukuqina kunye nesibheno sobuhle.
8. Usetyenziso:
- I-HEC ifumana izicelo ezahlukeneyo kumashishini afana nokwakha, iipeyinti kunye neengubo, izinto zokuncamathelisa, izithambiso, amayeza, amalaphu, kunye nokhathalelo lomntu. Isetyenziswe njenge-thickener, i-rheology modifier, i-ejenti yokugcina amanzi, i-stabilizer, ifilimu-yangaphambili, kunye ne-binder kwiindlela ezahlukeneyo kunye neemveliso.
9. Iingqwalasela zokusiNgqongileyo noKhuseleko:
- I-HEC ithathwe kwimithombo ye-cellulose ehlaziyiweyo kwaye i-biodegradable, iyenza ukuba ivumelane nokusingqongileyo. Kuthathwa njengekhuselekile ukusetyenziswa kwiimveliso zabathengi kwaye ihambelana neemfuno zolawulo kunye nemigangatho yomgangatho kumazwe ahlukeneyo.
Isishwankathelo, iHydroxyethyl Cellulose (HEC) yipolymer eguquguqukayo kwaye isetyenziswa ngokubanzi ngokutyeba okugqwesileyo, ukugcinwa kwamanzi, irheological, kunye neempawu zokwenza ifilim. Usetyenziso lwayo olwahlukeneyo kunye nokuhambelana nezinye izongezo zenza ukuba ibe sisithako esibalulekileyo kwimixube emininzi kunye neemveliso kuwo wonke amashishini.
