Ukuphuculwa kwesiphumo sodaka lwe-HPMC kwikhonkrithi

Kwiminyaka yakutshanje, kunye nophuhliso oluqhubekayo lweteknoloji yokufakelwa kwodonga lwangaphandle, inkqubela phambili eqhubekayo yeteknoloji yokuvelisa i-cellulose, kunye neempawu ezibalaseleyo ze-HP cellulose ngokwayo, i-HP cellulose isetyenziswe ngokubanzi kwishishini lokwakha. Ukuze uqonde ngokunzulu indlela ye-HP cellulose kunye nezinto ezisekelwe kwi-cement, eli phepha lizisa umphumo wokuphucula i-HP cellulose ekudibaneni kwezinto ezisekelwe kwi-cement.

ixesha lokumisela：

Ixesha lokubeka ikhonkrithi ikakhulu enxulumene nexesha lokumisa isamente, kwaye aggregate inefuthe elincinane, ngoko ke ixesha ukusetwa udaka ingasetyenziswa endaweni yokufunda isiphumo seselulosi HP kwixesha yokubeka phantsi kwamanzi non dispersible umxube eziphathekayo. Ekubeni ixesha lokumisa lomdaka lichaphazeleka ngumlinganiselo wesamente yamanzi kunye nesanti yesanti yesanti, ukwenzela ukuvavanya umphumo we-HP cellulose ngexesha lokumisela udaka, kuyimfuneko ukulungisa umlinganiselo wesamente yamanzi kunye nesanti yesanti yodaka.

Iziphumo zovavanyo zibonisa ukuba ukongezwa kwe-HP cellulose kunempembelelo ecacileyo yokunciphisa umxube wodaka, kwaye ixesha lokumisela lodaka lide kunye nokunyuka komxholo we-HP cellulose. Ngaphantsi komxholo ofanayo we-hp cellulose, ixesha lokumisela lodaka olwenziwe phantsi kwamanzi lide kunelo lenziwe emoyeni. Xa kulinganiswa emanzini, ixesha lokumisela lodaka oluxutywe ne-HP cellulose yi-6 ~ 18 h ilibazisekile ekusekweni kokuqala kunye ne-6 ~ 22 h ilibazisekile kwisimo sokugqibela xa kuthelekiswa nesampuli engenanto. Ke ngoko, i-HP cellulose kufuneka idityaniswe ne-arhente yamandla kwangoko.

I-HP cellulose yi-polymer ye-molecular ephezulu kunye ne-macromolecular linear structure kunye namaqela e-hydroxyl kumaqela asebenzayo, anokwenza iibhondi ze-hydrogen kunye neemolekyuli zamanzi ezixutywayo zokwandisa i-viscosity yamanzi okuxuba. Amatyathanga eemolekyuli amade e-HP cellulose atsala omnye komnye, esenza iimolekyuli ze-HP cellulose zidibanise ukwenza isakhiwo sothungelwano, esonga isamente kunye nokuxuba amanzi. Ngenxa yesakhiwo sothungelwano esifana nefilimu eyenziwe yi-HP cellulose kunye nesiphumo sayo sokusonga kwisamente, inokuthintela ngokufanelekileyo ukuphuphuma kwamanzi ngodaka kwaye ithintele okanye icothise isantya se-hydration yesamente.
