I-polymer powder e-redispersible iyona nto yokongeza esetyenziswa kwi-cementitious okanye kwi-gypsum-based based materials kushishino lokwakha. Ipowder yenziwe ngokutshiza-yomisa i-polymer dispersion, eyenza i-powder-flowing powder enokuthi ixutywe ngokulula kunye nezinye izithako ezomileyo. Kukho iintlobo ezininzi ezahlukeneyo zepolymer powder enokuphinda ihlakazwe ekhoyo, nganye ineempawu zayo kunye neempawu zayo. Kweli candelo, siza kujonga ezinye zezona ntlobo zixhaphakileyo zepolymer powder.

1. I-Vinyl acetate-ethylene (VAE) i-polymer powder ephindwe kabini

I-VAE yomgubo wepolymer edispersible yenye yezona ntlobo zisetyenziswa ngokuqhelekileyo zomgubo wepolymer odispersible kushishino lokwakha. Yenziwe nge-polymerizing vinyl acetate kunye ne-ethylene kwi-emulsion esekwe emanzini, ethi emva koko i-spray-yomiswe ukuze idale i-powder-flowing powder. I-VAE i-polymer powder edispersible i-polymer iyaziwa ngokugqwesa kwayo, ukuguquguquka, kunye nokumelana namanzi, okwenza kube yinto efanelekileyo yokusetyenziswa kwizicelo apho ukuqina kubalulekile, njengokulungiswa kwekhonkrithi, i-tile adhesive, kunye ne-insulation yangaphandle kunye neenkqubo zokugqiba (EIFS).

2. I-Vinyl acetate-based redispersible polymer powder

I-Vinyl i-acetate-based redispersible polymer powder yenziwe nge-polymerizing vinyl acetate kwi-emulsion yamanzi, ethi emva koko i-spray-yomiswe ukuze yenze i-polymer-flowing powder. Olu hlobo lomgubo lwepolymer oluphinda luhlakazwe luyaziwa ngokuncamathela kwawo okugqwesileyo, ukusebenza kakuhle, kunye nokumelana nokunyibilika komkhenkce, nto leyo eyenza ukuba ilungele ukusetyenziswa kwizicelo ezinje ngodaka, istucco, kunye neengubo zokuhombisa.

3. I-Acrylic-based redispersible polymer powder

I-Acrylic-based redispersible polymer powder yenziwe nge-polymerizing acrylic monomers kwi-emulsion esekwe emanzini, ethi ke itshizwe-yomisiweyo ukuze yenze umgubo okhululekileyo. I-Acrylic-based redispersible polymer powder yaziwa ngokugqwesa kwayo ukumelana namanzi, ukunamathela, kunye nokuguquguquka, iyenza ilungele ukusetyenziswa kwizicelo ezinje ngegrout, ukulungiswa kwekhonkrithi, kunye nokuncamathelisa iithayile.

4. I-Styrene-butadiene-based (SBR) i-polymer powder edispersible kwakhona

I-SBR i-polymer powder edispersible yenziwe nge-polymerizing styrene kunye ne-butadiene kwi-emulsion esekwe emanzini, ethi emva koko i-spray-yomiswe ukuze yenze i-polymerizing powder. Umgubo wepolymer odispersible we-SBR waziwa ngokuguquguquka okugqwesileyo, ukunamathela, kunye nokumelana namanzi, iyenza ilungele ukusetyenziswa kwizicelo ezinje ngodaka, igrout, kunye nokulungiswa kwekhonkrithi.

5. I-Ethylene-vinyl chloride (EVC) i-polymer powder edispersible kwakhona

EVC redispersible ipolymer powder yenziwe nge-polymerizing ethylene kunye ne-vinyl chloride kwi-emulsion esekwe emanzini, ethi ke isitshizi-yomisiweyo ukwenza umgubo okhululekileyo. I-EVC yomgubo wepolymer edispersible yaziwa ngokugqwesa kwayo ukumelana namanzi, ukuncamathela, kunye nokuguquguquka, iyenza ilungele ukusetyenziswa kwizicelo ezifana nokuncamathelisa kwethayile, ukulungiswa kwekhonkrithi, kunye ne-EIFS.

6. I-polymer powder enokuchithwa kwakhona kunye nesitashi esilungisiweyo

I-polymer powder ephinda iphindwe kwakhona kunye nesitashi esilungisiweyo senziwe ngokongeza isitashi esilungisiweyo kwi-emulsion yamanzi ngaphambi kokutshiza. Isitashi esilungisiweyo sisebenza njenge-dispersant, inceda ukuzinzisa i-emulsion kunye nokuphucula ukuphinda kuphindwe kwakhona kwe powder. Olu hlobo lomgubo lwepolymer oluphinda luhlakazwe luyaziwa ngokuncamathela okugqwesileyo, ukusebenza, kunye nokumelana namanzi, luyenza ilungele ukusetyenziswa kwizicelo ezinje ngodaka, igrout, kunye nodaka.

7. I-polymer powder enokuphinda ihlakazwe kunye ne-cellulose ether

I-polymer ephinda iphindwe kwakhona kunye ne-cellulose ether yenziwe ngokungeza i-cellulose ether kwi-emulsion yamanzi ngaphambi kokutshiza-yomisa. I-cellulose ether isebenza njenge-thickener, iphucula ukusebenza komgubo kunye nokunciphisa inani lamanzi afunekayo kumxube. Olu hlobo lomgubo wepolymer oludispersible luyaziwa ngokunamathela okugqwesileyo, ukusebenza kakuhle, kunye nokugcinwa kwamanzi, okwenza kube yinto efanelekileyo yokusetyenziswa kwizicelo ezifana nokunamathiswa kwetayile, i-grout, kunye ne-cementitious membrane membranes.
