MHEC LH 620M

EipponCell MHEC LH 620M methyl hydroxyethyl cellulose inoshandiswa mugypsum slurry kupa inooneka kukora mhedzisiro.Pakupisa kwekamuri, sezvo viscosity uye dosage ye cellulose ether inowedzera, kukora kwayo kunowedzera kujeka.Nekudaro, sezvo tembiricha inokwira, viscosity ye cellulose ether inodzikira, zvichikonzera kupera simba kwekukora kwayo.Izvi zvinotungamira kudzikira kwegoho rekuveura kushushikana, plastiki viscosity, uye pseudoplasticity yemusanganiswa wegypsum, zvichizoguma nekusashanda zvakanaka.

Cellulose ether inowedzera kuchengetwa kwemvura yegypsum.Nekudaro, sezvo tembiricha inowedzera, kuchengetwa kwemvura kwegypsum yakagadziridzwa kunoderera zvakanyanya uye kutorasikirwa zvachose nekugadzirisa kwekuchengetedza mvura pa60 ° C.Nhamba yekuchengetedza mvura yegypsum slurry inovandudzwa zvakanyanya ne cellulose ether, uye chiyero chekuchengetedza mvura zvishoma nezvishoma chinosvika pakuzara nekuwedzera kwehuwandu hweHPMC yakagadziridzwa gypsum slurry ine viscosities yakasiyana.Kazhinji, kuchengetwa kwemvura kwegypsum kwakaenzana ne viscosity ye cellulose ether, asi haina mhedzisiro payakanyanya viscosity.

Shanduko mukuchengetedza mvura kweselulosi ethers ine tembiricha yakanyatsoenderana neiyo microscopic morphology ye cellulose ethers muchikamu chemvura.Pane imwe nzvimbo, cellulose ether inowanzoita kuunganidza uye kuumba masangano makuru ecolloidal, zvichinyatso kuvharira nzira dzekuendesa mvura yemusanganiswa wegypsum kuti uwane kuchengetedza kwemvura.Zvisinei, sezvo tembiricha inokwira, iyo thermal gelation properties ye cellulose ether inokonzera iyo yakamboumbwa yakakura colloidal associations kuti ipararire zvakare, zvichiita kuti kuderera kwekuchengetedza mvura.
