Indlela yokusebenza ye-Redispersible Polymer Powder(RDP) odakeni olomile

I-Redispersible Polymer Powder(RDP)iyisengezo esibalulekile ekwakhiweni kodaka olomile, okunikeza uhla lwezinzuzo njengokunamathela okuthuthukisiwe, ukubumbana, ukuguquguquka, nokusebenza. Indlela yayo yokusebenza ibandakanya izigaba eziningi, kusukela ekuhlakazweni kwamanzi kuya ekusebenzelaneni nezinye izakhi kungxube yodaka. Ake sihlole indlela enemininingwane:

Ukuhlakazeka Emanzini:
Izinhlayiya ze-RDP zenzelwe ukuhlakazeka ngokushesha nangokufana emanzini ngenxa yemvelo yazo ye-hydrophilic. Ngemva kokwengezwa kwamanzi engxubeni yodaka olomile, lezi zinhlayiya ziyavuvukala futhi zihlakazeke, zenze ukumiswa kwe-colloidal okuzinzile. Le nqubo yokusabalalisa iveza indawo enkulu ye-polymer endaweni ezungezile, yenza kube lula ukusebenzisana okulandelayo.

Ukwakhiwa Kwefilimu:
Njengoba amanzi eqhubeka ehlanganiswa nodaka, izinhlayiya ze-RDP ezihlakazekile ziqala ukumanzisa, zenze ifilimu eqhubekayo ezungeze izinhlayiya zikasimende nezinye izakhi. Le filimu isebenza njengesithiyo, ivimbela ukuthintana okuqondile phakathi kwezinto ze-cementitious kanye nomswakama wangaphandle. Lokhu kubalulekile ekwehliseni ukungena kwamanzi, ukuqinisa ukuqina, kanye nokunciphisa ingcuphe ye-efflorescence nezinye izinhlobo zokuwohloka.

Ukunamathela Okuthuthukisiwe Nokubumbana:
Ifilimu ye-polymer eyakhiwe yi-RDP isebenza njenge-ejenti ebophayo, ekhuthaza ukunamathela phakathi kodaka nama-substrates ahlukahlukene njengokhonkolo, amatshe, noma amathayela. Ifilimu iphinde ithuthukise ukuhlangana ngaphakathi kwe-matrix yodaka ngokuvala izikhala phakathi kwezinhlayiya, ngaleyo ndlela ithuthukise amandla kanye nobuqotho bodaka oluqinile.

Ukuvumelana nezimo kanye nokumelana ne-Crack:
Enye yezinzuzo ezibalulekile ze-RDP ikhono layo lokudlulisela ukuguquguquka ku-matrix yodaka. Ifilimu ye-polymer ithatha ukunyakaza okuncane kwe-substrate kanye nokwandiswa kokushisa, ukunciphisa ingozi yokuqhekeka. Ukwengeza, i-DPP ithuthukisa amandla okuqina kanye ne-ductility yodaka, ithuthukise ukumelana kwayo nokuqhekeka ngaphansi kwemithwalo emile neguquguqukayo.

Ukugcinwa kwamanzi:
Ukuba khona kwe-RDP enhlanganisweni yodaka kusiza ukulawula ukugcinwa kwamanzi, ukuvimbela ukuhwamuka okusheshayo phakathi nezigaba zokuqala zokwelashwa. Lesi sikhathi esinwetshiwe se-hydration sikhuthaza ukugcwala kwe-cement okuphelele futhi siqinisekisa ukuthuthukiswa okuphelele kwezakhiwo zemishini, njengamandla okucindezela nokuguquguquka. Ngaphezu kwalokho, ukugcinwa kwamanzi okulawulwayo kunomthelela ekusebenzeni okuthuthukisiwe kanye nesikhathi sokuvula isikhathi eside, kube lula ukusetshenziswa nokuqedwa kodaka.

Ukuthuthukisa Ukuqina:
Ngokuthuthukisa ukunamathela, ukuguquguquka, kanye nokumelana nokuqhekeka, i-DPP ithuthukisa kakhulu ukuqina kwezicelo zodaka olomile. Ifilimu ye-polymer isebenza njengesithiyo esivikelayo ekungeneni komswakama, ukuhlaselwa kwamakhemikhali, nokungcola kwemvelo, ngaleyo ndlela inwebe impilo yesevisi yodaka futhi yehlise izidingo zokunakekelwa.

Ukuhambisana Nezengezo:
I-RDPibonisa ukuhambisana okuhle kakhulu nezithasiselo ezihlukahlukene ezivame ukusetshenziswa ekwakhiweni kodaka olomile, njengezifaka umoya, ama-accelerator, ama-retarders, nama-pigments. Lokhu kuguquguquka kuvumela ukwenziwa ngokwezifiso kwezakhiwo zodaka ukuze kuhlangatshezwane nezidingo ezithile zokusebenza zezinhlelo zokusebenza ezahlukahlukene nezimo zemvelo.

indlela yokusebenza ye-polymer powder ehlakazekayo odakeni olomile ihlanganisa ukuhlakazeka emanzini, ukwakheka kwefilimu, ukunamathela okuthuthukisiwe nokubumbana, ukuguquguquka nokuphikiswa kokuqhekeka, ukugcinwa kwamanzi, ukuthuthukiswa kokuqina, nokuhambisana nezithasiselo. Le miphumela ehlanganisiwe inikela ekusebenzeni okuthuthukisiwe, ukusebenza, nokuqina kwamasistimu odaka olomile kuzo zonke izinhlelo zokusebenza zokwakha.
