I-Hydroxyethyl Methyl Cellulose (MHEC)
I-Methyl Hydroxyethyl Cellulose(MHEC/HEMC)
CAS:9032-42-2
I-Hydroxyethyl Methyl Cellulose(HEMC) ibizwa nangokuthiI-Methyl Hydroxyethyl Cellulose(MHEC), i-ether ye-cellulose eguquguqukayo, esebenza kakhulu esetshenziswa njenge-ejenti yokugcina amanzi esebenza kahle, i-stabilizer, i-adhesives kanye ne-ejenti eyenza ifilimu ngezinhlobo zezinto zokwakha.MHEC/HEMC isetshenziswa kabanzi ekusetshenzisweni kwezimboni, njengokwakha, okokuhlanza, upende nokumboza, nathi singanikeza i-HEMC ngokwezidingo zamakhasimende. Ngemuva kokulungiswa okulungisiwe kanye nokuphathwa kwendawo, singathola izimpahla ezihlakazeka emanzini ngokushesha, sandise isikhathi esivulekile, anti-sagging, njll.

Isakhiwo Samakhemikhali se-MHEC
I-MHEC ikhiqizwa nguetherifying cellulose yemvelongeamaqembu e-methyl kanye ne-hydroxyethyl. Lezi zinguquko ziyayithuthukisaukuncibilika kwamanzi, i-viscosity, nokuhambisanangezinto ezahlukene.
Izici ezibalulekile ze-MHEC:
- Ukunyibilika kwamanzi: Kuncibilika emanzini ashisayo nabandayo, okwenza izixazululo ezicacile.
- Ikhono Lokuqina: Inikeza i-viscosity ephezulu kanye nokulawula okuhle kakhulu kwe-rheology.
- Ukugcinwa Kwamanzi: Kuvimbela ukulahlekelwa kwamanzi emikhiqizweni esekwe usimende kanye ne-gypsum, ukuthuthukisa ukuphulukiswa nokunamathela.
- I-Non-Ionic Nature: Ihambisana nezinhlobonhlobo zamakhemikhali, kufaka phakathi usawoti kanye nama-surfactants.
- Ikhono Lokwenza Ifilimu: Idala amafilimu aguquguqukayo futhi ahlala isikhathi eside, anenzuzo ekumbozeni nasekusetshenzisweni kwemithi.
- Ukuzinza Kwe-Thermal: Ingazweli ekushiseni, iyenze ifanele ukusetshenziswa kwezinga lokushisa eliphezulu.

Izinzuzo Zokusebenzisa i-MHEC
✔ Ukugcinwa Kwamanzi Okuhle Kakhulu - Kuvimbela ukomiswa ngaphambi kwesikhathi ekwakhiweni nasekusetshenzisweni kwezimonyo.
✔ Ukunamathela Okuthuthukisiwe - Kuthuthukisa amandla okubopha kuma-adhesives namathayela.
✔ Izinzile Kububanzi Obubanzi be-pH - Isebenza ngempumelelo ezindaweni ezine-asidi, ezingathathi hlangothi, nezine-alkaline.
✔ I-Non-Ionic Compatibility - Isebenza kahle ngosawoti, ama-surfactants, namanye ama-polymer.
✔ Ithuthukisa I-Rheology kanye Nezakhiwo Ezigelezayo - Ivumela i-viscosity elawulwayo, ivimbele ukuconsa nokuhlehla.
Ukupakisha:
