1. Ukugcinwa kwamanzi
Ukugcinwa kwamanzi kwi-plastering mortar kubalulekile.IHydroxypropyl Methylcellulose (HPMC)inomthamo oqinileyo wokugcina amanzi. Emva kokongeza i-HPMC kwi-plastering mortar, inokwenza isakhiwo senethiwekhi yokugcina amanzi ngaphakathi kwi-mortar ukuthintela amanzi ukuba angafunxwa okanye aphele ngokukhawuleza yisiseko. Umzekelo, xa u-plastering kwiziseko ezomileyo, ukuba akukho manyathelo afanelekileyo okugcina amanzi, amanzi kwi-mortar aya kufunxwa ngokukhawuleza yisiseko, nto leyo ebangela ukuba isamente ingafumani amanzi aneleyo. Ubukho be-HPMC bufana "ne-micro-reservoir". Ngokwezifundo ezifanelekileyo, i-plastering mortar enomlinganiselo ofanelekileyo we-HPMC inokugcina umswakama iiyure ezininzi okanye iintsuku ezinde kunezo ngaphandle kwe-HPMC phantsi kwendawo efanayo. Oku kunika isamente ixesha elaneleyo lokufumana i-hydration reaction, ngaloo ndlela kuphucula amandla kunye nokuqina kwe-plastering mortar.
Ukugcinwa kwamanzi ngokufanelekileyo kunokuphucula ukusebenza kwe-plaster mortar. Ukuba i-mortar ilahlekelwa ngamanzi ngokukhawuleza, iya koma kwaye kube nzima ukuyisebenzisa, ngelixa i-HPMC inokugcina i-plasticity ye-mortar, ukuze abasebenzi bokwakha babe nexesha elaneleyo lokulinganisa nokuthambisa i-plaster mortar.
2. Ukunamathela
I-HPMC inokuphucula kakhulu ukunamathelana phakathi kwe-plaster mortar kunye nesiseko. Ineempawu ezilungileyo zokubopha, ezinokwenza i-mortar inamathele ngcono kumphezulu wesiseko njengeendonga kunye nekhonkrithi. Kwiindlela ezisebenzayo, oku kunceda ukuthintela ukugoba nokuwa kwe-plaster mortar. Xa iimolekyuli ze-HPMC zidibana nomphezulu wesiseko kunye namasuntswana angaphakathi kwe-mortar, kwakheka inethiwekhi yokubopha. Umzekelo, xa kufakwa i-plaster kumphezulu wekhonkrithi egudileyo, i-plaster mortar ene-HPMC eyongeziweyo inokudityaniswa ngokuqinileyo kumphezulu, iphucule uzinzo lwesakhiwo sonke sokubeka i-plaster, kwaye iqinisekise umgangatho weprojekthi yokubeka i-plaster.
Kwiziseko ezenziwe ngezinto ezahlukeneyo, i-HPMC inokudlala indima entle yokuphucula ukubopha. Nokuba yisiseko somthi, somthi okanye sesinyithi, lo gama nje sikwindawo apho kufuneka khona udaka lweplasta, i-HPMC inokuphucula ukusebenza kokubopha.
3. Ukusebenza kakuhle
Ukuphucula ukusebenza kakuhle. Ukongezwa kwe-HPMC kwenza ukuba i-plastering mortar isebenziseke lula, kwaye i-mortar iba thambile kwaye igude, nto leyo elula ukusebenza kolwakhiwo. Abasebenzi bokwakha banokusasaza kwaye bakrwele i-mortar ngokulula xa beyisebenzisa, nto leyo enciphisa ubunzima kunye nomsebenzi wokwakha. Oku kubaluleke kakhulu kwiiprojekthi ezinkulu ze-plastering, ezinokuphucula ukusebenza kakuhle kolwakhiwo kunye nomgangatho.
I-Anti-degrading. Xa iplasta ibekwe kwiindawo ezithe nkqo okanye ezithambekileyo, i-plaster mortar idla ngokugoba, oko kukuthi, i-mortar ihla phantsi kwesenzo somxhuzulane. I-HPMC inokunyusa i-viscosity kunye nokuhambelana kwe-mortar kwaye imelane ngempumelelo nokugoba. Ivumela i-mortar ukuba ihlale kwindawo esetyenzisiweyo ngaphandle kokutyibilika okanye ukuhamba nokubola, ukuqinisekisa ukuba i-plaster ithambile kwaye intle. Umzekelo, kulwakhiwo lwe-plastering lweendonga zangaphandle zezakhiwo, i-plaster mortar ene-HPMC eyongeziweyo inokulungelelanisa kakuhle neemfuno zokwakha iindonga ezithe nkqo, kwaye isiphumo sokwakha asiyi kuchaphazeleka kukugoba.
4. Amandla nokuqina
Ukusukela okoI-HPMCkuqinisekisa ukufuma okupheleleyo kwesamente, amandla e-plastering mortar ayaphucuka. Okukhona i-samente hydration ephezulu, kokukhona imveliso ye-hydration engakumbi iveliswa. Ezi mveliso ze-hydration ziyadibaniswa ukuze zenze isakhiwo esiqinileyo, ngaloo ndlela ziphucula izalathisi zamandla e-mortar, ezifana nokucinezelwa kunye namandla e-flexural. Ekuhambeni kwexesha, oku kunceda ukuphucula ukuqina kwe-plastering mortar.
Ngokuphathelele ukuqina, i-HPMC inokudlala indima ethile ekumelaneni neentanda. Inciphisa ukuvela kokuqhekeka kokoma okubangelwa kukufuma okungalinganiyo ngokugcina ukusasazwa okufanayo kokufuma kwi-mortar. Kwangaxeshanye, isiphumo sokugcina amanzi se-HPMC senza i-mortar imelane nokukhukuliseka kwezinto zangaphandle zendalo ngexesha lokusetyenziswa ixesha elide, njengokuthintela ukungena ngokugqithisileyo kokufuma, ukunciphisa umonakalo kwisakhiwo se-mortar obangelwa yimijikelo yokuqandisa, njl.njl., ngaloo ndlela yandisa ubomi benkonzo ye-mortar yokuplasta.
