Yintoni i-viscosity ye-hydroxyethyl cellulose?

I-Hydroxyethylcellulose (HEC) i-nonionic, i-polymer enyibilikayo emanzini ephuma kwi-cellulose. Ngenxa yeempawu zayo ezizodwa ze-rheological, idla ngokusetyenziswa kumashishini ahlukeneyo kuquka amayeza, izithambiso kunye nokwakhiwa. Enye yezinto eziphambili ze-hydroxyethyl cellulose yi-viscosity yayo, edlala indima ebalulekileyo ekunqumeni ukusebenza kwayo kwizicelo ezahlukeneyo.

I-Viscosity ngumlinganiselo wokuxhathisa kolwelo ukuhamba. Kwimeko ye-hydroxyethylcellulose, i-viscosity yayo ichaphazeleka kwizinto ezininzi, kubandakanywa ukugxila, ubushushu kunye nesantya se-shear. Ukuqonda le miba kubalulekile ekwandiseni ukusetyenziswa kwe-HEC kwimixube eyahlukeneyo.

I-viscosity ye-hydroxyethylcellulose ixhomekeke kakhulu ekugxininiseni kwayo kwisisombululo. Ngokubanzi, njengoko i-HEC igxininisa, i-viscosity yayo iyanda. Oku kuziphatha kuqhelekile kwizisombululo zepolymer kwaye kaninzi kuchazwa yimodeli yomthetho wamandla ehambelana ne-viscosity ekugxininiseni.

Ubushushu bunempembelelo ebalulekileyo kwi-viscosity ye-hydroxyethyl cellulose solutions. Kwiimeko ezininzi, i-viscosity iyancipha ngokunyuka kweqondo lokushisa. Olu buntununtunu beqondo lobushushu bubalulekile kwizicelo apho izinto kufuneka zitshintshe kwi-viscosity, njengexesha lokuvelisa okanye xa zisetyenziswa kwiindawo ezahlukeneyo.

Ireyithi yokucheba yenye into ebalulekileyo echaphazela i-viscosity ye-hydroxyethyl cellulose. Isantya sokucheba sibhekiselele kwisantya apho umaleko wolwelo olusondeleyo ushukuma xa uthelekiswa omnye komnye. I-viscosity yezisombululo ze-HEC ngokuqhelekileyo ibonisa ukuziphatha kokucheba, oku kuthetha ukuba njengoko izinga lokucheba linyuka, i-viscosity iyancipha. Le propati inenzuzo kwizicelo ezifana neengubo kunye ne-adhesives apho kulula ukufaka isicelo.

Ubunzima bemolekyuli ye-hydroxyethyl cellulose ikwamisela i-viscosity yayo. Ubunzima bemolekyuli obuphezulu be-HECs bavame ukuba ne-viscosities ephezulu kwindawo yoxinzelelo. Olu phawu lubalulekile xa ukhetha ibakala elithile le-HEC kwisicelo esithile.

Kuqulunqo lwamayeza, i-hydroxyethylcellulose isetyenziswa ngokuqhelekileyo njenge-ejenti yokuqina kwiifom zedosi yomlomo kunye neyezihloko. I-viscosity ye-HEC iqinisekisa ukumiswa okufanelekileyo kweengqungquthela kwaye inika ukulungelelaniswa okufunekayo kwi-dosing elula. Ngaphezu koko, ukuziphatha kwe-chear-thinning ye-HEC kunokuphucula ukusasazeka kwezinto ezixutywayo.

Kwishishini lezithambiso, i-hydroxyethylcellulose isetyenziswa kwiimveliso ezahlukeneyo, kubandakanya iishampu, iiloshini kunye neekhrimu. Iimpawu zayo zokuguqula i-viscosity zinceda ukuphucula ukuzinza kunye nokuthungwa kwezi zakhiwo, ngaloo ndlela ziphucula amava omsebenzisi jikelele.

Kwishishini lokwakha, i-hydroxyethylcellulose isoloko isetyenziswa njenge-thickener kwimveliso esekwe kwisamente. I-viscosity ye-HEC inceda ukulawula ukuhamba kunye nokuqhutyelwa kwezinto eziphathekayo ngexesha lokusetyenziswa. Oku kubaluleke kakhulu kwizicelo ezifana nokunamathiswa kweetayile kunye ne-grouts.

I-viscosity ye-hydroxyethyl cellulose yiparameter ephambili echaphazela ukusebenza kwayo kwizicelo ezahlukeneyo. Ukuqonda izinto ezichaphazela i-viscosity, ezifana nokugxininiswa, ukushisa, kunye nesantya sokucheba, kubalulekile ekuphuculeni ukusetyenziswa kwe-HEC kumashishini ahlukeneyo. Njengepolymer eguquguqukayo, i-hydroxyethyl cellulose iyaqhubeka nokudlala indima ebalulekileyo ekuphuculeni ukusebenza kweemveliso ezahlukeneyo kumashishini ahlukeneyo.
