I-HPMC I-Hydroxypropyl methyl cellulose kudaka lwesamente kunye ne-gypsum slurry, ikakhulu idlala indima yokugcina amanzi kunye nokuqina, inokuphucula ngokufanelekileyo ukunamathela kunye nokumelana ne-sag ye-slurry.
Ubushushu bomoya, iqondo lobushushu kunye noxinzelelo lomoya kunokuchaphazela isantya sokumka kwamanzi kudaka lwesamente kunye neemveliso ezisekwe kwigypsum.Ke kumaxesha ahlukeneyo onyaka, ukongeza i-hydroxypropyl methyl cellulose ubungakanani obufanayo besiphumo sokugcina amanzi kwimveliso kunomahluko othile.Kulwakhiwo lwekhonkrithi, umphumo wokugcinwa kwamanzi we-slurry unokulungiswa ngokunyuka okanye ukunciphisa inani le-HPMC.Ukugcinwa kwamanzi kwe-methyl cellulose ether kwiqondo lokushisa eliphezulu luphawu olubalulekileyo lokuhlukanisa umgangatho we-methyl cellulose ether.
Iimveliso ezigqwesileyo ze-hydroxypropyl methyl cellulose zinokucombulula ngempumelelo ingxaki yokugcinwa kwamanzi phantsi kobushushu obuphezulu.Kwixesha lobushushu eliphezulu, ingakumbi kwiindawo ezishushu nezomileyo kunye nokwakhiwa umaleko obhityileyo kwicala enelanga, imfuneko HPMC umgangatho ophezulu ukuphucula ukugcinwa kwamanzi ludaka;i-hydroxypropyl methyl cellulose (HPMC), ukufana kuhle kakhulu, yioksijini kunye ne-oksijini ye-hydroxypropyl amaqela asasazwa ngokulinganayo kunye netyathanga le-cellulose, inokuphucula i-hydroxyl kunye ne-ether ioksijini kunye namanzi kwisitshixo sokudibanisa i-hydrogen bonding isakhono, ukwenza amanzi asimahla e-hydration, ukuze ulawule ngokufanelekileyo imozulu eshushu ebangelwa kukufuma ukuba kube ngumphunga, Ukufumana ukugcinwa kwamanzi aphezulu.
Umgangatho ophezulu we-hydroxypropyl methyl cellulose unokusasaza ngokulinganayo nangokufanelekileyo kudaka lwesamente kunye neemveliso zesamente, kwaye upakishe onke amasuntswana aqinileyo, kwaye wenze umaleko wefilimu yokumanzisa, ukufuma kwisiseko ixesha elide kukhutshwe ngokuthe ngcembe, kunye ne-inorganic cementitious material hydration reaction. , ukwenzela ukuba kuqinisekiswe amandla ebhondi kunye namandla oxinzelelo lwezinto.
Kulwakhiwo, ukuze kuphunyezwe umphumo wokongiwa kwamanzi, kufuneka ukongeza umgangatho ophezulu weemveliso ze-HPMC ngokuhambelana nefomula, kungenjalo, kuya kubakho ukomisa ngokukhawuleza okubangelwa ukungonelanga kwamanzi, ukunciphisa amandla, ukuqhekeka, igubu elingenanto kunye nomgangatho wokulahla. iingxaki, kodwa ukwandisa ubunzima bokwakha abasebenzi.Njengoko iqondo lobushushu liyancipha, umthamo wamanzi we-HPMC unokuncitshiswa ngokuthe ngcembe, kwaye umphumo ofanayo wokugcinwa kwamanzi unokufumaneka.
