Indlela yokusebenza kwe-Redispersible Polymer Powder (RDP) ku-dry mortar

I-Powder ye-Polymer ephinde ihlakazeke (RDP)iyisengezo esibalulekile ekwakhiweni kwe-dry mortar, enikeza izinzuzo ezahlukahlukene njengokunamathela okuthuthukisiwe, ukuhlangana, ukuguquguquka, kanye nokusebenza kahle. Indlela esebenza ngayo ihilela izigaba eziningi, kusukela ekuhlakazekeni emanzini kuya ekusebenzelaneni nezinye izingxenye engxubeni ye-mortar. Ake sihlolisise indlela eningiliziwe yokusebenza:

Ukuhlakazeka Emanzini:
Izinhlayiya ze-RDP zenzelwe ukusabalala ngokushesha nangokulinganayo emanzini ngenxa yemvelo yazo yokunamathela emanzini. Lapho kungezwa amanzi engxubeni yodaka owomile, lezi zinhlayiya ziyavuvukala futhi zihlakazeke, zakha ukumiswa okuzinzile kwe-colloidal. Le nqubo yokuhlakazeka iveza indawo enkulu ebusweni be-polymer endaweni ezungezile, okwenza kube lula ukusebenzisana okulandelayo.

Ukwakhiwa Kwamafilimu:
Njengoba amanzi eqhubeka nokufakwa engxubeni ye-mortar, izinhlayiya ze-RDP ezihlakazekile ziqala ukumanzisa, zakha ifilimu eqhubekayo ezungeze izinhlayiya eziqinisayo nezinye izakhi. Le filimu isebenza njengesivikelo, ivimbela ukuxhumana okuqondile phakathi kwezinto eziqinisayo nomswakama wangaphandle. Lokhu kubalulekile ekunciphiseni ukungena kwamanzi, kwandise ukuqina, futhi kuncishiswe ingozi yokukhanya kwelanga kanye nezinye izinhlobo zokuwohloka.

Ukunamathela Nokubambisana Okuthuthukisiwe:
Ifilimu ye-polymer eyakhiwe yi-RDP isebenza njenge-ejenti yokubopha, ikhuthaza ukunamathelana phakathi kwe-mortar kanye ne-substrates ezahlukahlukene ezifana nekhonkrithi, ukwakhiwa kwetshe, noma amathayili. Ifilimu iphinde ithuthukise ukuhlangana ngaphakathi kwe-mortar matrix ngokuvala izikhala phakathi kwezinhlayiya, ngaleyo ndlela ithuthukise amandla kanye nobuqotho be-mortar eqinile.

Ukuguquguquka kanye nokumelana nokuqhekeka:
Enye yezinzuzo ezibalulekile ze-RDP yikhono layo lokunikeza ukuguquguquka ku-matrix yodaka. Ifilimu ye-polymer ivumela ukunyakaza okuncane kwe-substrate kanye nokwanda kokushisa, kunciphisa ingozi yokuqhekeka. Ngaphezu kwalokho, i-DPP ithuthukisa amandla okudonseka kanye nokuguquguquka kodaka, ithuthukisa kakhulu ukumelana kwayo nokuqhekeka ngaphansi kwemithwalo eqinile neguquguqukayo.

Ukugcinwa Kwamanzi:
Ukuba khona kwe-RDP engxubeni ye-mortar kusiza ukulawula ukugcinwa kwamanzi, ukuvimbela ukuhwamuka okusheshayo phakathi nezigaba zokuqala zokuqina. Lesi sikhathi somswakama eside sikhuthaza ukugcinwa okuphelele kwe-samente futhi siqinisekisa ukuthuthukiswa okuhle kwezakhiwo zemishini, njengokuqina kokucindezela kanye nokuguquguquka. Ngaphezu kwalokho, ukugcinwa kwamanzi okulawulwayo kunegalelo ekuthuthukiseni ukusebenza kahle kanye nesikhathi eside sokuvula, okwenza kube lula ukusetshenziswa kanye nokuqedwa kwe-mortar.

Ukuthuthukiswa Kokuqina:
Ngokuthuthukisa ukunamathela, ukuguquguquka, kanye nokumelana nokuqhekeka, i-DPP ithuthukisa kakhulu ukuqina kokusetshenziswa kodaka olomile. Ifilimu ye-polymer isebenza njengesivikelo sokuvikela ekungeneni komswakama, ukuhlaselwa ngamakhemikhali, kanye nokungcola kwemvelo, ngaleyo ndlela yandisa impilo yenkonzo yodaka futhi inciphise izidingo zokulungisa.

Ukuhambisana Nezithasiselo:
I-RDPIbonisa ukuhambisana okuhle kakhulu nezithasiselo ezahlukahlukene ezivame ukusetshenziswa ekwakhiweni kwe-dry mortar, njenge-air entrainers, i-accelerators, i-retarders, kanye ne-pigment. Lokhu kuguquguquka kuvumela ukwenza ngezifiso izakhiwo ze-mortar ukuze kuhlangatshezwane nezidingo ezithile zokusebenza kwezicelo ezahlukene kanye nezimo zemvelo.

Indlela yokusebenza kwempuphu ye-polymer ehlakazekayo ku-dry mortar ihilela ukuhlakazeka emanzini, ukwakheka kwefilimu, ukunamathela okuthuthukisiwe kanye nokuhlangana, ukuguquguquka kanye nokumelana nokuqhekeka, ukugcinwa kwamanzi, ukuthuthukiswa kokuqina, kanye nokuhambisana nezithasiselo. Le miphumela ehlanganisiwe inegalelo ekusebenzeni okuthuthukisiwe, ukusebenza kahle, kanye nokuqina kwezinhlelo ze-dry mortar kuzo zonke izinhlelo zokusebenza zokwakha ezahlukahlukene.
