I-MHEC LH 660M

I-EipponCell MHEC LH 660M i-methyl hydroxyethyl cellulose isetyenziselwa udaka lwesamente eludaka, kwaye i-viscosity yayo iyanda ngokuqhubekayo.Isakhiwo sothungelwano lwe-molekyuli ye-cellulose ether idibanisa kunye nesakhiwo sothungelwano lweemveliso ze-cement hydration.I-hydration yokuqala yesamente iphakamisa ngokungathanga ngqo ukuxinana kwe-cellulose ether, okukhokelela "kwi-composite superposition effect" kwi-viscosity yesisombululo se-cellulose ether kunye ne-cement slurry.Ngenxa yoko, i-viscosity yoludaka lwesamente elungisiweyo ene-cellulose ether iphezulu kakhulu kunesixa see-viscosities zabo.

Zombini i-cellulose ether eguqulelwe ngodaka lwesamente kunye nodaka lwesamente esulungekileyo zibonisa ukuchetywa kwe-chear okanye ukuziphatha kwe-pseudoplastic.I-pseudoplasticity ye-cellulose ether eguqulelwe ngodaka lwesamente isezantsi xa kuthelekiswa naleyo yodaka lwesamente ecocekileyo.Ngamazinga aphantsi okujikeleza okanye kunye ne-viscosity ephantsi ye-cellulose ether eguqulwayo ye-sement slurry okanye umxholo we-cellulose ether ephantsi, i-pseudoplasticity ye-cellulose ether eguqulelwe i-sement slurry iba yinto ecacileyo ngakumbi.

Njengoko iqondo lobushushu linyuka, isantya kunye nobungakanani besamente hydration ukwanda, okukhokelela ekunyukeni ngokuthe ngcembe i-viscosity ye-sement slurry ecocekileyo.I-viscosity ye-cement paste elungisiweyo, nangona kunjalo, iyahluka kunye nobushushu ngenxa yezakhono ezahlukeneyo zokuthintela iintlobo ezahlukeneyo kunye nezixa ze-cellulose ethers kwi-cement hydration.
