1. Ukuthuthukisa ukugcinwa kwamanzi kodaka
I-Hydroxypropyl methylcellulose (HPMC) Ingabe i-ejenti enhle kakhulu yokugcina amanzi edonsa ngempumelelo futhi igcina amanzi ngokwakha isakhiwo senethiwekhi efanayo ku-mende. Lokhu kugcinwa kwamanzi kungandisa isikhathi samanzi okuhwamuswa kwamanzi kudaka futhi kunciphise izinga lokulahleka kwamanzi, ngaleyo ndlela kubambezele isilinganiso se-hydration reaction raction futhi kunciphisa ukuqhekeka kwevolumu okubangelwa ukuhwamuka kwamanzi okusheshayo. Ngasikhathi sinye, isikhathi esivulekile esivulelekile nesikhathi futhi sisiza ukuthuthukisa ikhwalithi yokwakha futhi sinciphise amathuba okufa.
2. Ukuthuthukisa Ukusebenza kanye Rheology of Botar
I-HPMC ingaguqula ukubonwa kodaka, okwenza kube lula ukusebenza. Lokhu kuthuthukiswa akugcini nje ngokuthuthukisa uketshezi nokusebenza kodaka, kepha futhi kukhulisa ukunamathela kwalo nokumbozwa kwesembozo. Ngaphezu kwalokho, i-CoxinCel®HPMC ingaphinde yehlise ukuhlukaniswa kanye ne-peater pegpet e-wonga
3. Thuthukisa ukunamathela kanye nokuqhekeka kokulwa kodaka
Ifilimu ye-viscoelastic esungulwe yi-HPMC kuDinga ingagcwalisa ama-pores ngaphakathi kodaka, ithuthukise ubuntu bodaka, futhi ithuthukise ukunamathela kodaka kuya engxenyeni engezansi. Ukwakheka kwale filimu akugcini nje ngokuqinisa ukwakheka okuphelele kodaka, kepha futhi kunomthelela wokuvinjwa ekwandisweni kwama-microcracks, ngaleyo ndlela kuthuthukiswe kakhulu ukumelana nodaka kodaka. Ngaphezu kwalokho, isakhiwo se-polymer se-HPMC singasabalalisa ukucindezela ngesikhathi senqubo yodaka, sinciphise ukucindezela okubangelwa imithwalo yangaphandle noma ukuguqulwa kwe-substrate, futhi kusize ukuvikela ukuthuthukiswa okwengeziwe kwemifantu.
4. Lawula i-shrinkage kanye ne-shrinkage yepulasitiki yodaka
Mortar is prone to shrinkage cracks due to water evaporation during the drying process, and the water retention property of HPMC can delay water loss and reduce the volume shrinkage caused by shrinkage. Ngaphezu kwalokho, i-HPMC ingabuye inciphise ubungozi bokuqhekeka kwepulasitiki kokuqhekeka, ikakhulukazi esigabeni sokuqala sodaka. Ilawula ijubane lokufuduka nokusatshalaliswa kwamanzi, kunciphisa ukungezwani kwe-capillary kanye nokuxineka okungaphezulu, futhi kunciphisa ngempumelelo amathuba okuqhekeka endaweni yodaka.
I-5. Thuthukisa ukumelana kweqhwa kweqhwa
Ukungezwa kwe-HPMC nakho kungakhulisa ukumelana nokungamelana ne-durse-thaw yodaka. Ukugcinwa kwayo kwamanzi kanye nekhono elenziwe ngefilimu lisiza ukunciphisa izinga lokuqabula kwamanzi emotweni ngaphansi kwezimo zokushisa eziphansi, ukugwema ukulimala kwesakhiwo sodaka ngenxa yokwandiswa kwevolumu ngenxa yokwandiswa kwethamo. Ngaphezu kwalokho, ukusebenza kahle kwesakhiwo se-pore of mongar yi-HPMC kunganciphisa futhi umthelela wemijikelezo ye-freeze -tha-thaw ekumelaneni nokuqhekeka kodaka.

I-HPMC isonde isikhathi sokuphendula kwe-hydration sodaka, okuvumela imikhiqizo ye-Cement Hydration ukugcwalisa ngodaka ngodaka ngokulinganayo futhi kuthuthukise ubungako bodaka. Lokhu kusebenza kwe-microssmcure kunganciphisa ukukhiqizwa kweziphembe zangaphakathi, ngaleyo ndlela kuthuthukise ukumelana nokuqhekeka okuphelele kodaka. Ngaphezu kwalokho, i-polymer chain ye-HPMC ingakha ukusebenzisana okuthile nomkhiqizo we-hydration, ngcono ukuthuthukisa amandla nokumelana nokuqhekeka kodaka.

ICECCINCHELX ®PPMC inika udaka ukuguquguquka okuthile nokungazethembi kwezimo eziguqukayo, ukuze kukwazi ukuzivumelanisa kangcono nemvelo yangaphandle lapho inezinguquko zangaphandle noma izinguquko zokushisa. Le mpahla yokutholwa kwamandla ibaluleke kakhulu ukumelana nokuqhekeka, okunganciphisa ukwakheka nokwanda kwemifantu nokwenza ngcono ukuqina kwesimanje kwesikhathi eside.
I-HPMC kuthuthukisa ukumelana nokuqhekeka kodaka kusuka ezicini eziningi ngokugcinwa kwayo okuhlukile, ukunxusa kanye nekhono lokwakheka kwamafilimu, okubandakanya ukunciphisa ukusebenzelana kodaka, ukunciphisa ukumiswa kwe-shrinkage kanye nokunamathela, ukunweba isikhathi esivulekile kanye nekhono le-anti-freeze-freeze-reashe-thaw. Ezintweni zesimanje zokwakha, i-HPMC isiphenduke inhlanganisela ebalulekile yokuthuthukisa ukumelana nodaka ngodaka, futhi amathemba awo okufaka isicelo abanzi kakhulu.
