I-Anti-Dispersion ye-Hydroxypropyl Methylcellulose(HPMC) esetyenziswa kwi-Concrete Admixtures

IHydroxypropyl methylcellulose (HPMC) yipolymer esetyenziswa ngokuqhelekileyo kushishino lokwakha njengesongezo kwimixube yekhonkrithi. Umsebenzi wayo oyintloko kukusebenza njenge-arhente yokugcina amanzi, okunceda ukuphucula ukusebenza kwekhonkrithi kunye nokunciphisa umthamo wamanzi afunekayo.

I-Anti-dispersion ligama elisetyenziselwa ukuchaza amandla e-HPMC ukuthintela ukuhlukana kwamacandelo omxube wekhonkrithi, njenge-aggregates, i-samente, kunye namanzi. Ngamanye amazwi, kuyanceda ukugcina umxube ufana kwaye uthintele amacandelo ukuba ahlukane okanye azinzise.

Ukufezekisa iipropati ezilungileyo zokulwa nokusabalalisa, i-HPMC kufuneka ibe nobunzima obuphezulu be-molecular kwaye ihlakazwe ngokufanelekileyo kumxube wekhonkrithi. I-HPMC kufuneka kwakhona ihambelane namanye amacandelo kumxube kwaye ikwazi ukugcina uzinzo kunye nokusebenza kwayo ekuhambeni kwexesha.

Ukongeza kwiipropati zayo zokulwa nokusabalalisa, i-HPMC inokuphucula ukusebenza ngokubanzi kwekhonkrithi, kuquka amandla ayo, ukuqina, kunye nokuchasana nokuqhekeka. Ikwayindlela ehambelana nokusingqongileyo kwezinye izongezo zekhemikhali ezisetyenziswa rhoqo kushishino.

Ngokubanzi, ukusetyenziswa kwe-HPMC kwi-concrete admixtures kunokunceda ukuphucula ukusebenza kunye nokusebenza kwekhonkrithi, ngelixa kunciphisa impembelelo yokusingqongileyo kwimisebenzi yokwakha.
