I-MHEC LH 660M

I-EipponCell MHEC LH 660M i-methyl hydroxyethyl cellulose isetshenziswa kusimende eludaka oludaka, futhi i-viscosity yayo ikhula ngokuqhubekayo.Isakhiwo senethiwekhi yamangqamuzana ye-cellulose ether ihlangana nesakhiwo senethiwekhi yemikhiqizo ye-cement hydration.I-hydration yokuqala kasimende ngokungaqondile iphakamisa ukugcwala kwe-cellulose ether, okuholela "kumphumela we-superposition oyinhlanganisela" ku-viscosity yesisombululo se-cellulose ether kanye nodaka lukasimende.Ngenxa yalokho, i-viscosity ye-slurry yesimende eshintshiwe ene-cellulose ether iphakeme kakhulu kunesamba sama-viscosity awo ngamanye.

Kokubili i-cellulose ether eguquliwe usimende nodaka oluhlanzekile lukasimende kukhombisa ukuncishiswa kwe-shear noma ukuziphatha okuyi-pseudoplastic.I-pseudoplasticity ye-cellulose ether eguquliwe usimende slurry iphansi uma iqhathaniswa naleyo yodaka lukasimende olumsulwa.Ngamazinga aphansi okuzungeza noma nge-viscosity ephansi ye-cellulose ether eshintshiwe usimende slurry noma okuqukethwe kwe-cellulose ether ephansi, i-pseudoplasticity ye-cellulose ether eguquliwe usimende slurry iba sobala kakhulu.

Njengoba izinga lokushisa likhuphuka, isivinini kanye nezinga likasimende liyakhula, okuholela ekwandeni kancane kancane kwe-viscosity ye-purecement slurry.I-viscosity yokunamathisela usimende oshintshiwe, nokho, iyahlukahluka kuye ngezinga lokushisa ngenxa yamakhono ahlukene okuvimbela izinhlobo ezihlukahlukene kanye namanani e-cellulose ethers ekufakweni kukasimende.
