1. Ukugcinwa Kwamanzi
Ukugcinwa kwamanzi ku-plastering mortar kubalulekile.I-Hydroxypropyl Methylcellulose (HPMC)inomthamo oqinile wokugcina amanzi. Ngemva kokufaka i-HPMC ku-plastering mortar, ingakha isakhiwo senethiwekhi yokugcina amanzi ngaphakathi ku-mortar ukuvimbela amanzi ukuthi angamuncwa noma aphele ngokushesha yi-base. Isibonelo, lapho u-plastering ezisekelweni ezomile, uma kungekho zindlela ezinhle zokugcina amanzi, amanzi ku-mortar azomuncwa ngokushesha yi-base, okuholela ekutheni i-simende ingamanzi ngokwanele. Ukuba khona kwe-HPMC kufana "ne-micro-reservoir". Ngokusho kwezifundo ezifanele, i-plastering mortar enenani elifanele le-HPMC ingagcina umswakama amahora amaningana noma ngisho nezinsuku ezinde kunaleyo ngaphandle kwe-HPMC ngaphansi kwendawo efanayo. Lokhu kunikeza i-simende isikhathi esanele sokusabela ekumuncweni kwamanzi, ngaleyo ndlela kuthuthukiswe amandla nokuqina kwe-plastering mortar.
Ukugcinwa kwamanzi okufanele kungathuthukisa nokusebenza kahle kwe-plastering mortar. Uma i-mortar ilahlekelwa amanzi ngokushesha kakhulu, izokoma futhi kube nzima ukuyisebenzisa, kuyilapho i-HPMC ingagcina i-plasticity ye-mortar, ukuze izisebenzi zokwakha zibe nesikhathi esanele sokulinganisa nokushelela i-plaster mortar.
2. Ukunamathela
I-HPMC ingathuthukisa kakhulu ukunamathelana phakathi kodaka lwe-plaster kanye nesisekelo. Inezakhiwo ezinhle zokubopha, okungenza udaka lunamathele kangcono ebusweni besisekelo njengezindonga kanye nokhonkolo. Ezisetshenzisweni ezisebenzayo, lokhu kusiza ukuvimbela ukugoba nokuwa kodaka lwe-plaster. Lapho ama-molecule e-HPMC ehlangana nobuso besisekelo kanye nezinhlayiya ezingaphakathi kodaka, kwakheka inethiwekhi yokubopha. Isibonelo, lapho kuplastwa ezinye izindawo ezibushelelezi zekhonkolo, udaka lwe-plaster olune-HPMC eyengeziwe lungahlanganiswa ngokuqinile nobuso, kuthuthukiswe ukuzinza kwesakhiwo sonke sokuplasta, futhi kuqinisekiswe ikhwalithi yephrojekthi yokuplasta.
Ngezisekelo zezinto ezahlukene, i-HPMC ingadlala indima enhle yokuthuthukisa ukubopha. Kungakhathaliseki ukuthi isisekelo sokhuni, sokhuni noma sensimbi, uma nje sisendaweni lapho kudingeka khona udaka lwe-plaster, i-HPMC ingathuthukisa ukusebenza kokubopha.
3. Ukusebenza kahle
Thuthukisa ukusebenza kahle. Ukwengezwa kwe-HPMC kwenza udaka lokuplasta lusebenze kalula, futhi udaka luba lula futhi lube bushelelezi, okuyinto elula ukusebenza kokwakha. Izisebenzi zokwakha zingasakaza futhi ziklwebhe udaka kalula uma zilusebenzisa, okunciphisa ubunzima kanye nomsebenzi wokwakha. Lokhu kubaluleke kakhulu kumaphrojekthi amakhulu okuplasta, okungathuthukisa ukusebenza kahle kokwakha kanye nekhwalithi.
Ukungaguquguquki. Uma uplasta ezindaweni eziqondile noma ezithambekele, udoti wokuplasta uthambekele ekuguquguqukeni, okungukuthi, udoti ugeleza phansi ngaphansi kwesenzo samandla adonsela phansi. I-HPMC ingandisa ukujiya kanye nokuvumelana kodoti futhi imelane ngempumelelo nokuguquguquka. Ivumela udoti ukuthi uhlale endaweni esetshenziswayo ngaphandle kokushelela phansi noma ukugeleza nokuwohloka, okuqinisekisa ukuthi udoti uthambile futhi muhle. Isibonelo, ekwakhiweni kokuplasta kwezindonga zangaphandle zezakhiwo, udoti wokuplasta one-HPMC eyengeziwe ungavumelana kahle nezidingo zokwakha izindonga eziqondile, futhi umphumela wokwakha ngeke uthintwe ukuguquguquka.
4. Amandla nokuqina
KusukelaI-HPMCkuqinisekisa ukumuncwa okuphelele kwesimende, amandla esimende sokuplasta ayathuthuka. Uma izinga lokumuncwa kwesimende liphezulu, kukhiqizwa imikhiqizo yokumuncwa eningi. Le mikhiqizo yokumuncwa ihlanganiswa ukuze yakhe isakhiwo esiqinile, ngaleyo ndlela ithuthukise izinkomba zamandla esimende, njengokucindezela kanye namandla okugoba. Ngokuhamba kwesikhathi, lokhu kusiza futhi ekuthuthukiseni ukuqina kwesimende sokuplasta.
Ngokuphathelene nokuqina, i-HPMC ingadlala indima ethile ekumelaneni nokuqhekeka. Inciphisa ukwenzeka kokuqhekeka kokuma okubangelwa umswakama ongalingani ngokugcina ukusatshalaliswa okufanayo komswakama ku-mortar. Ngesikhathi esifanayo, umphumela wokugcina amanzi we-HPMC wenza i-mortar imelane nokuguguleka kwezinto zangaphandle zemvelo ngesikhathi sokusetshenziswa isikhathi eside, njengokuvimbela ukungena ngokweqile komswakama, ukunciphisa umonakalo esakhiweni se-mortar okubangelwa imijikelezo yokuqandisa nokuncibilika, njll., ngaleyo ndlela kwandise impilo yenkonzo ye-mortar yokuplasta.
