Ukugcinwa kwamanzi ngumlinganiselo wokusetyenziswa kwakhona kwe-HPMC hydroxypropyl methylcellulose, ukugcinwa kwamanzi kokulungileyo nokubi kwakhona kuchatshazelwa ngabavelisi abaninzi basekhaya bodaka olomileyo, ngakumbi imozulu yobushushu obuphezulu bengqwalasela yomzi-mveliso wasezantsi, kwangaxeshanye, bekukho izizathu ezininzi ezichaphazela iziphumo. amanzi odaka omgubo omileyo, njengokongeza umthamo, i-viscosity, i-particle fineness kunye nokusetyenziswa kokusingqongileyo, ubushushu, njl.
Kwinkqubo yodaka oluxutyiweyo oluxutywe ngaphambili, inani elongezelelweyo le-hydroxypropyl methyl cellulose liphantsi.Nangona isixa esongezelelweyo siphantsi, sinokuphucula ngokucacileyo ukusebenza kodaka olumanzi, olukwayinto eyongezelelweyo echaphazela ukwakhiwa kodaka.Ke ngoko, ukhetho lwesayensi kunye nolufanelekileyo lwe-cellulose ether eneempawu ezahlukeneyo, i-viscosity eyahlukileyo, ukucolwa kwamasuntswana ahlukeneyo kunye nesixa sokongeza kunempembelelo enkulu ekuphuculeni ukusebenza kodaka oluxutyiweyo oluxutyiweyo.
Kwimeko yendawo yokwakha yangoku, ngoku uninzi lwe-masonry kunye nokutyatyekwa kwamanzi ukusebenza kwamanzi akulunganga, indawo ezolileyo imizuzu embalwa iya kuba kukwahlulwa kwe-slurry yamanzi, kunye nokugcinwa kwamanzi yi-hydroxypropyl methylcellulose ether indima enkulu, i-cellulose ether enyibilikayo emanzini. Udaka olulungelelanisiweyo lunendima ebaluleke ngakumbi, indima yomphezulu ophambili ineentathu, enye, Ukusebenza kakuhle kokugcinwa kwamanzi ngokulinganayo, okwesibini, impembelelo yokungaguquguquki kunye ne-thixotropy yodaka oluxutyiweyo, okwesithathu, impembelelo yokunxibelelana nesamente. .Ukugcinwa kwamanzi kwi-Hydroxypropyl methylcellulose kuxhomekeke kwisiseko sokufunxa kwamanzi, ukubunjwa kodaka, udaka lodaka, kunye neemfuno zamanzi odaka, kunye nexesha lokujiya kwemathiriyeli ye-condensation, yokugcina i-cellulose ether self water, ikakhulu ukusuka ekunyibilikeni kwendalo kunye nokuphelelwa ngamanzi emzimbeni. kwi-celluloseether.
I-Hydroxypropyl methylcellulose idlala indima ebalulekileyo kwinkqubo yodaka oluxutyiweyo oluxutyiweyo, olunokuthi ludlale indima yokugcina amanzi, ukuqina, ukulibazisa amandla e-hydration ye-samente, kwaye inokuphucula ukusebenza kokwakhiwa.Ukusebenza kakuhle kokugcinwa kwamanzi kunokwenza i-samente hydration iphelele ngakumbi, inokuphucula i-viscosity emanzi yodaka olumanzi, ukuze kuphuculwe amandla okubopha udaka, kodwa kunokulungelelanisa ixesha.Ukongeza i-hydroxypropyl methylcellulose ether kwinkqubo yodaka olomileyo oluxutywe oluxutywe lunokuphucula ukwakhiwa kodaka, kunokuphucula amandla okwakhiwa, ukwenzela ukuba kusetyenziswe ngokubanzi kwintsimi yokusetyenziswa kodaka.
