I-Viscosity ye-hydroxyethyl cellulose

I-Hydroxyethyl cellulose (HEC) yi-nonionic, i-polymer enyibilikayo emanzini esetyenziswa ngokubanzi njengento enzima, i-stabilizer, kunye ne-binder kumashishini ahlukeneyo, kuquka amayeza, izinto zokuthambisa kunye nokwakha. I-viscosity yayo idlala indima ebalulekileyo ekunqumeni ukusebenza kwayo kwezi zicelo.

I-viscosity ye-HEC igqitywe ngamanani ezinto, kubandakanywa i-degree of substitution (DS), ubunzima be-molecular, i-concentration, kunye ne-pH. Iqondo lokutshintshwa libhekisela kwinani lamaqela e-hydroxyethyl afakwe kwi-molecule ye-cellulose, ngelixa ubunzima be-molecular bubhekisela kubukhulu bamakhonkco e-polymer. Ukugxininiswa kwe-HEC kwisisombululo kuchaphazela i-viscosity yayo, kunye noxinzelelo oluphezulu olukhokelela kwi-viscosities ephezulu. I-pH yesisombululo nayo inokuba nefuthe kwi-viscosity, kunye namaxabiso aphezulu e-pH ngokubanzi okukhokelela kwii-viscosities ezisezantsi.

I-viscosity ye-HEC inokulinganiswa ngokusebenzisa i-viscometer, elinganisa ukuchasana kwamanzi okuhamba. Iindidi ezahlukeneyo ze-viscometers zingasetyenziselwa, kubandakanywa i-viscometers ejikelezayo kunye ne-capillary viscometers, kuxhomekeke kwisicelo esithile kunye noluhlu lwe-viscosity yomdla.

Ngokubanzi, i-HEC ephezulu ye-viscosity ikhethwa kwizicelo apho ukuqina nokuzinzisa kubaluleke kakhulu, njengokuqulunqa amayeza, izimonyo, kunye neemveliso zokhathalelo lomntu. Ngokomzekelo, i-HEC ephezulu ye-viscosity isoloko isetyenziselwa i-shampoos kunye ne-conditioners ukuphucula ukuthungwa kunye nokusebenza kwazo, kunye neekhrimu kunye ne-lotions ukunika imvakalelo egudileyo, enqabileyo.

Kwishishini lokwakha, i-HEC isetyenziswa njenge-ejenti yokuqina kunye nokugcinwa kwamanzi kwiimveliso ezisekelwe kwisamente, ezifana nodaka, i-grouts, kunye nekhonkrithi. I-viscosity ye-HEC kwezi zicelo ibalulekile ekufezekiseni umsebenzi ofunekayo, ukunamathela, kunye nokuhambelana kwemveliso yokugqibela.

I-viscosity ye-HEC inokuguqulwa ngeendlela ezahlukeneyo zeekhemikhali kunye nezomzimba, kubandakanywa i-crosslinking, i-acid hydrolysis, kunye nokudibanisa nezinye iipolymers. Olu hlengahlengiso lunokuguqula iipropati ze-HEC kwaye lubangele ukusebenza okuphuculweyo kwizicelo ezithile.

Isishwankathelo, i-viscosity ye-HEC yinto ebalulekileyo ekunqumeni ukusebenza kwayo kwizicelo ezahlukeneyo. Iqondo lokutshintshwa, ubunzima bemolekyuli, ugxininiso, kunye ne-pH zonke zidlala indima ekumiseleni i-viscosity yayo, enokulinganiswa ngokusebenzisa i-viscometer. Amashishini ahlukeneyo kunye nezicelo zinokufuna amanqanaba ahlukeneyo e-viscosity, kwaye ukuguqulwa kwe-HEC kunokwenziwa ukuphucula ukusebenza kwayo kwizicelo ezithile.
