IHydroxypropyl methylcellulose (HPMC) yipolymer eguquguqukayo edla ngokusetyenziswa kwizakhiwo ezihonjisiweyo zekhonkrithi ezihonjisiweyo ngeenjongo ezahlukeneyo. Oku kwalekeneyo kusetyenziswe kumphezulu okhoyo wekhonkrithi ukunyusa umdla wabo wobuhle, ukuqina, kunye nokusebenza.
1.Intshayelelo kwi-HPMC kwi-Architectural Decorative Concrete Overlays
Izakhelo zekhonkrithi ezihonjisiweyo zoyilo lukhetho oludumileyo ekuphuculeni imbonakalo kunye nokusebenza komgangatho wekhonkrithi kwiindawo zokuhlala kunye nezorhwebo. Olu lwalekayo lubonelela ngeendleko ezingezinye zezixhobo zemveli ezifana nelitye, izitena, okanye ithayile, ngelixa libonelela ngokuyilwa okungapheliyo. I-HPMC idlala indima ebalulekileyo ekwenziweni kwezi kwalekeneyo, inegalelo kwiimpawu zazo zokuncamathelisa, ukusebenza, kunye nokuqina.
2.Ukubambelela kunye nokuBonding
Omnye wemisebenzi ephambili ye-HPMC kwizakhiwo ezihonjisiweyo zekhonkrithi kukuphucula ukuncamathelisa kunye nokudibanisa phakathi kwezinto ezingaphezulu kunye ne-substrate yekhonkrithi ekhoyo. I-HPMC isebenza njenge-binder, yenza ibhondi eyomeleleyo enceda ukuthintela i-delamination kunye nokuqinisekisa ukusebenza kwexesha elide. Ngokwandisa ukuncamathelisa, i-HPMC inceda ukudala indawo engenamthungo kunye neyomeleleyo exhathisa ukuxobuka, ukuqhekeka, kunye nokugqabhuka.
3.Ukusebenza kunye nokungaguquguquki
I-HPMC isebenza njengento yokuqinisa kunye ne-rheology modifier kwizakhiwo ezihonjisiweyo zekhonkrithi, ezivumela iikontraka ukuba zifezekise ukusetyenzwa okufunekayo kunye nokungaguquguquki ngexesha lokufaka isicelo. Ngokulungelelanisa i-viscosity yomxube ogqithisiweyo, i-HPMC inceda ukuqinisekisa ukuhamba okufanelekileyo kunye nokubambelela, ukuququzelela ukusasazeka lula kunye nokulinganisa kwi-concrete substrate. Oku kukhokelela ekugqityweni okugudileyo kunye nokufana okufanayo, ukunyusa inkangeleko yonke yokwaleka.
4.Ukugcinwa kwamanzi kunye noLawulo
Ukongeza ekuphuculeni ukubambelela kunye nokusebenza, i-HPMC ikwanceda ukulawula ukugcinwa kwamanzi kwizakhiwo ezihonjisiweyo zekhonkrithi. Ngokwenza ifilimu ekhuselayo phezu komphezulu wezinto ezingaphezulu, i-HPMC inciphisa ukulahleka komswakama ngexesha lokunyanga, ukuthintela ukomisa kwangaphambi kwexesha kunye nokuqinisekisa ukuhanjiswa okufanelekileyo kwamacandelo e-cementitious. Oku kunceda ukunciphisa ukucutheka, ukuqhekeka, kunye neziphene ezingaphezulu, okukhokelela ekugqityweni okuhlala ixesha elide kunye nokuthandeka kobuhle.
5.I-Crack Bridging kunye noKuhlala ixesha elide
Ukuqhekeka ngumba oqhelekileyo kwi-concrete overlays ngenxa yezinto ezifana nokuhamba kwe-substrate, ukuguquguquka kweqondo lokushisa, kunye nokunciphisa ukomisa. I-HPMC inceda ukuthomalalisa le ngxaki ngokwandisa ukuguquguquka kunye nokuqhekeka kwezakhono zokudibanisa izinto ezingaphezulu. Ngokwenza i-matrix eyomelelayo ekwaziyo ukuhambisa iintshukumo ezincinci ze-substrate kunye noxinzelelo, i-HPMC inceda ukuthintela ukwanda kweentanda kunye nokugcina ingqibelelo yomgangatho ongaphezulu ngexesha. Oku kubangela ukugqitywa kokuhlobisa okuhlala ixesha elide kunye nexesha elide elifuna ukulungiswa okuncinci.
6.Ukuphucula iziphumo zokuhombisa
Ngaphandle kweempawu zayo zokusebenza, i-HPMC ikwadlala indima ekwandiseni iziphumo zokuhombisa zokwaleka kwekhonkrithi yezakhiwo. Ngokusebenza njengomphathi wee-pigments, iidayi, kunye nee-aggregates zokuhombisa, i-HPMC ivumela iikontraka ukuba zenze imibala yesiko, ukuthungwa, kunye neepatheni ezihambelana nokusingqongileyo. Nokuba kuphinda-phindwa inkangeleko yelitye lendalo, ithayile, okanye umthi, uphahla olusekwe kwiHPMC lubonelela ngamathuba oyilo angapheliyo kubayili, abayili, kunye nabanini beepropathi.
IHydroxypropyl methylcellulose (HPMC) yipolymer esebenza ngeendlela ezininzi esebenza ngeenjongo ezahlukeneyo kwizakhiwo ezihonjisiweyo zekhonkrithi. Ukusuka ekuphuculeni ukuncamathela kunye nokusebenza ukuya ekwandiseni ukuqina kunye neziphumo zokuhombisa, i-HPMC idlala indima ebalulekileyo ekwenziweni nasekusebenzeni kwezi zalekayo. Ngokubandakanya i-HPMC kwiiprojekthi zabo, iikontraka zinokufikelela kwiziphumo ezigqwesileyo ezihlangabezana nobuhle, ukusebenza, kunye neemfuno zokwenziwa koyilo loyilo lwangoku.
