I-Function Mechanism ye-Redispersible Polymer Powder

I-Redispersible polymer powder (RDP) iyisibophezelo se-polymer esetshenziswa kabanzi ekwakhiweni kodaka lwe-drymix. Umsebenzi oyinhloko we-RDP ukuthuthukisa amandla okubopha, ukusebenza, nokuqina kodaka lwe-drymix.

Indlela yokusebenza ye-RDP ku-drymix mortars ibandakanya izinyathelo ezimbalwa:

1. Ukwakhiwa kwefilimu: Uma i-RDP yengezwa odakeni lwe-drymix, yenza ifilimu ebusweni bezinhlayiya zengxube eyomile. Le filimu isiza ukwandisa ukunamathela phakathi kwezinhlayiya futhi ithuthukise amandla okubopha odaka.
2. I-Plasticization: I-RDP iphinde isebenze njenge-plasticizer ku-drymix mortar, okusho ukuthi isiza ukuthuthukisa ukusebenza nokusebenza kwengxube. Lokhu kufezwa ngokunciphisa i-viscosity yengxube nokwenza kube lula ukuxuba nokusebenzisa.
3. Ukugcina amanzi: I-RDP ingakwazi ukumunca futhi ibambelele emanzini, okusiza ukugcina udaka lungenamanzi futhi lusebenze isikhathi eside. Lokhu kubaluleke kakhulu kuma-drymix mortars adinga ukuthuthwa futhi agcinwe isikhathi eside.
4. Ukuvumelana nezimo: I-RDP ingase futhi ithuthukise ukuguquguquka nokuqina kodaka lwe-drymix. Lokhu kufezwa ngokuthuthukisa ukuqina nokuqina kwengxube, okusiza ukunciphisa amathuba okuqhekeka nezinye izinhlobo zokulimala.

Sekukonke, indlela yokusebenza ye-RDP ku-drymix mortar isekelwe ekhonweni layo lokwenza ifilimu, isebenze njenge-plasticizer, igcine amanzi, futhi ithuthukise ukuguquguquka nokuqina kwengxube. Lezi zakhiwo zenza i-RDP ibe isithasiselo esibalulekile sokuthuthukisa ukusebenza kanye nekhwalithi yodaka lwe-drymix.
