I-HPMC kwi-Wet Mortars
I-JINJI® Hydroxypropyl Methyl Cellulose (HPMC) yi-polymer ye-cellulose ether ye-non-ionic esekelwe kwi-cellulose, i-polymer yendalo ephuma kwi-cotton linter ecocekileyo.
I-HPMC inokuphucula umanyano kunye nokugcinwa kwamanzi omxube wodaka lwe-Spray.
Izinga lokugcinwa kwamanzi sisalathiso esibalulekileyo sokusebenza kweSpray Mortar. Ngelixa ezinye iinxalenye zodaka kunye nekhonkrithi zifana, zisebenza ngokwahlukileyo. Ngokuqhelekileyo, ikhonkrithi igalelwa kwikhonkrithi kunye nomsebenzi womthi ogcina amanzi amaninzi. Udaka ludla ngokusetyenziswa kwiindawo ezifunxa amanzi, kwaye ukufuma eludongeni kulahleka ngokulula okanye kukhuphe umoya emoyeni, ngoko ke ukugcinwa kwamanzi kodaka kuba kubaluleke ngakumbi kunoko lwekhonkrithi.
Isizathu sokuba kutheni i-HPMC iphucula ukuhambelana kodaka lwesitshizi kukugcina amanzi, kunokuphucula ukuhambelana kodaka, ukunciphisa izinga lokopha kodaka ukuya kumlinganiselo othile, kodwa kuphuculwe ukuguquguquka kodaka lokutshiza ngaphakathi koluhlu oluthile lwedosi; Nangona kunjalo, umxholo ophezulu we-Hydroxpropyl Methyl Cellulose wenza udaka olumanzi-umxube ludityaniswe kakhulu, olunciphisa umbane wodaka kwaye lwenza ukuba udaka lube ngumngeni ngakumbi ukwakha.
I-HPMC inokunyusa ukomelela kokuqina kokuqina kodaka oluxutyiweyo olumanzi.
Ukutyalwa kodaka, amandla ebhondi luphawu olubalulekileyo. Ngokuqhelekileyo, ukutyabeka udaka kufuna ukusebenza kakuhle. Ukuze wenze umaleko wodaka olufanayo kwindawo yokwakha. Amandla okubambisana okunamandla omdaka angenza ukuba udaka kunye nomgangatho wesiseko unamathele ngokuqinileyo, kwaye ukusetyenziswa kwexesha elide akuyi kubangela ukuqhekeka nokuwa.
I-cellulose ether kunye neengqungquthela ze-hydration zenza umgca omncinci wefilimu ye-polymer enefuthe lokutywinwa kunye nokuthintela ukulahleka kwamanzi, kunye nokugcinwa kwamanzi okulungileyo, ukwenzela ukuba kube nomswakama owaneleyo wokuqinisekisa ukuphuhliswa kwe-hydration kunye namandla e-samente kunye nokuphucula amandla okubambisana. yentlama. Kwelinye icala, iHydroxpropyl Methyl Cellulose iphucula ukudityaniswa kodaka lokutshiza ukuze kuqinisekiswe ukubakho kweplastiki elungileyo kunye nokuguquguquka, kunciphisa uxinzelelo lokutyibilika phakathi kodaka lokutshiza kunye nojongano lwesampulu ye-substrate, kwaye iphucula ngakumbi isakhono sokudibanisa udaka.
Kunconywa ukuba ngexesha lokulungiselela inkqubo, i-HPMC ixutywe kwi-sprayer mortar ngendlela yesisombululo kunokuba idibaniswe ngokuthe ngqo kunye nefom yepowder.
Owokuqala unempembelelo engcono ekuphuculeni ukugcinwa kwamanzi, ukudibanisa, kunye neempawu zomatshini zodaka lokutshiza. Xa umxholo oguqulwayo we-Hydroxpropyl Methyl Cellulose ukwinqanaba le-0.01% ~ 0.04%, izinga lokugcinwa kwamanzi kwe-HPMC kwifom yesisombululo yi-1.4% ~ 3.0% ephezulu kuneyo powdered HPMC kwi-spray mortar. Ngoko ke, i-HPMC exutywe ngendlela yesisombululo inempembelelo engcono ekuphuculeni ukugcinwa kwamanzi kwi-spray mortar.
