I-Hydroxy Ethyl Cellulose (HEC) Yazisa
I-Hydroxyethyl cellulose (HEC) yipolima enyibilikayo emanzini ephuma kwi-cellulose, eyipolima yendalo efumaneka kwizityalo. I-HEC yenziwe ngokuzisa amaqela e-hydroxyethyl kwi-cellulose backbone ngokusebenzisa i-chemical reaction. Olu hlengahlengiso luphucula ukunyibilika kwamanzi kunye nezinye iipropathi zeselulosi, zenza ukuba zilungele usetyenziso lwemizi-mveliso eyahlukeneyo. Nantsi intshayelelo yeHEC:
- Isakhiwo seMichiza: I-HEC igcina isiseko esisisiseko se-cellulose, esiyi-polysaccharide yomgca ehlanganiswe ngokuphindaphindiweyo kweeyunithi ze-glucose ezidityaniswe yi-β-1,4-glycosidic bond. Ukuqaliswa kwamaqela e-hydroxyethyl (-CH2CH2OH) kwi-backbone ye-cellulose inika ukunyibilika kwamanzi kunye nezinye izinto ezinqwenelekayo kwi-HEC.
- IiPropati zeMpahla: I-HEC idla ngokufumaneka njengomgubo ocolekileyo, omhlophe ukuya komhlophe. Ayinavumba kwaye ayinancasa. I-HEC iyanyibilika emanzini kwaye yenza izisombululo ezicacileyo, ezicacileyo. I-viscosity yezisombululo ze-HEC zinokuhluka ngokuxhomekeke kwizinto ezifana nokugxininiswa kwe-polymer, ubunzima be-molecular, kunye nobushushu.
- IiPropati eziSebenzayo: I-HEC ibonisa iipropathi ezininzi ezisebenzayo eziyenza ibe luncedo kwizicelo ezahlukeneyo:
- Ukutyeba: I-HEC i-thickener esebenzayo kwiinkqubo ezinamanzi, inika i-viscosity kunye nokuphucula iimpawu ze-rheological zezisombululo kunye ne-dispersions.
- Ukugcinwa kwamanzi: I-HEC ineempawu ezibalaseleyo zokugcina amanzi, okwenza kube luncedo kwiimveliso apho ukulawulwa komswakama kubalulekile.
- Ukwenziwa kweFilimu: I-HEC inokwenza iifilimu ezicacileyo, eziguquguqukayo xa zomiswe, eziluncedo kwiingubo, ukunamathela, kunye neemveliso zokunyamekela.
- Ukuzinza: I-HEC iphucula ukuzinza kunye nobomi beshelufu bokuqulunqwa ngokuthintela ukuhlukana kwesigaba, i-sedimentation, kunye ne-syneresis.
- Ukuhambelana: I-HEC iyahambelana noluhlu olubanzi lwezinye izithako, ezibandakanya i-salts, i-acids, kunye ne-surfactants, evumela ukuqulunqwa kokuguquguquka kunye nokuguquguquka.
- Izicelo: I-HEC ifumana ukusetyenziswa okubanzi kumashishini ahlukeneyo, kuquka:
- Ulwakhiwo: Isetyenziswa kwimveliso esekwe kwisamente enje ngodaka, igrouts, kunye nerenders njengento etyebisayo, iarhente yokugcina amanzi, kunye nerheology modifier.
- Iipeyinti kunye neeNgqungquthela: Isetyenziswa njenge-thickener, stabilizer, kunye ne-rheology modifier kwiipeyinti ezisekelwe emanzini, iingubo kunye nokunamathiswa.
- IiMveliso zoNonophelo loBuqu: Ifunyenwe kwiishampu, ii-conditioners, iikhrimu, iiloshini, kunye neegel njenge-thickener, stabilizer, kunye nefilimu yangaphambili.
- Amachiza: Isetyenziswa njenge-binder, disintegrant, kunye ne-viscosity modifier kwiipilisi, ii-capsules, kunye ne-suspensions.
- Ishishini lokuTya: Isetyenziswa njenge-thickener, stabilizer, kunye ne-emulsifier kwiimveliso zokutya ezifana neesosi, iilokhwe, isuphu, kunye neemveliso zobisi.
I-Hydroxyethyl cellulose (HEC) yipolymer eguquguqukayo enoluhlu olubanzi lwezicelo kuwo wonke amashishini ahlukeneyo, apho inegalelo ekusebenzeni, ukuzinza, kunye nokusebenza kweemveliso ezininzi kunye nokuqulunqwa.
