I-HPMC ikakhulu idlala indima yokugcina amanzi kunye nokujiya kwi-samente yodaka kunye ne-gypsum-based slurry, enokuthi iphucule ngokufanelekileyo ubumbano kunye nokuxhatshazwa kwe-sag ye-slurry.
Izinto ezifana nobushushu bomoya, ubushushu kunye noxinzelelo lomoya ziyakuchaphazela izinga lokumka kwamanzi kudaka lwesamente kunye neemveliso ezisekwe kwigypsum.Ngoko ke, ngamaxesha ahlukeneyo, ukongeza inani elifanayo le-HPMC, umphumo wokugcinwa kwamanzi weemveliso unomahluko othile.Ukugcinwa kwamanzi kwe-methyl cellulose ether kwiqondo lokushisa eliphezulu luphawu olubalulekileyo lokuhlukanisa umgangatho we-methyl cellulose ether.I-HPMC egqwesileyo inokusombulula ngempumelelo ingxaki yokugcinwa kwamanzi phantsi kobushushu obuphezulu.Ngamaxesha obushushu obuphezulu, ngakumbi kwiindawo ezishushu nezomileyo kunye nolwakhiwo olubhityileyo kwicala elinelanga, i-HPMC ekumgangatho ophezulu iyafuneka ukuze kuphuculwe ukugcinwa kwamanzi kwi-slurry.Umgangatho ophezulu we-HPMC, kunye nokufana okuhle kakhulu, amaqela ayo e-methoxy kunye ne-hydroxypropoxy asasazwa ngokulinganayo kunye nekhonkco ye-cellulose yemolekyuli, enokuphucula amandla e-athom ze-oksijini kwi-hydroxyl kunye neebhondi ze-ether ukudibanisa namanzi ukwenza iibhondi ze-hydrogen, ukuze amanzi akhululekileyo aba ngamanzi abophekileyo, ukuze kulawulwe ngokufanelekileyo ukufuduka kwamanzi okubangelwa yimozulu yobushushu obuphezulu kunye nokufezekisa ukugcinwa kwamanzi aphezulu.
Umgangatho ophezulu we-cellulose we-HPMC unokuthi uhlakazwe ngokulinganayo kwaye ngokufanelekileyo kwiimveliso ze-samente kunye ne-gypsum-based based, kwaye ifake zonke iinqununu eziqinileyo, kwaye zenze ifilimu yokumanzisa, kwaye ukufuma kwisiseko kukhishwa ngokuthe ngcembe kwixesha elide.I-hydration reaction ye-coagulating material iyenzeka, ngaloo ndlela iqinisekisa amandla okudibanisa kunye namandla oxinzelelo lwezinto.Ke ngoko, kulwakhiwo lobushushu obuphezulu ehlotyeni, ukuze kufezekiswe umphumo wokugcinwa kwamanzi, kuyimfuneko ukongeza iimveliso ze-HPMC ezikumgangatho ophezulu ngokwefomula, kungenjalo kuya kubakho ukungonelanga kwe-hydration, ukunciphisa amandla, ukuqhekeka, ukugoba kunye nokuwa. okubangelwa kukomisa ngokukhawuleza.Kwakhona kwandisa ubunzima bokwakha kubasebenzi.Njengoko iqondo lobushushu liyehla, isixa esongezelelweyo se-HPMC sinokuncitshiswa ngokuthe ngcembe, kwaye umphumo ofanayo wokugcinwa kwamanzi unokufumaneka.
