Kwi-mortar, i-redispersible polymer powder inokuphucula iimpawu zokwakha zobunjineli ze-rubber powder, iphucule ukunyibilika kwe-rubber powder, iphucule i-thixotropy kunye nokumelana nokuwa, iphucule amandla adibeneyo e-rubber powder, iphucule ukunyibilika kwamanzi, kwaye yonyuse ixesha xa ivulelwa kwihlabathi langaphandle. Emva kokuba i-samente mortar yomile kwaye iqina, inokunyusa amandla okuxinwa, yonyuse amandla okutsalwa, inciphise i-elastic mold, kwaye iphucule ukucaciswa. I-redispersible polymer powder inomqamelo omhle wokwakha ifilimu, kwaye ukusetyenziswa kwayo kunokubonwa kwiiprojekthi zokwakha kunye nokuhombisa.
Ifilimu ye-latex yerabha yerabha ye-resin inesakhiwo esizitsalelayo, esinokukhulula amandla axhasayo aye kwi-joint ene-anchor yesamente. Ngokwalo mandla angaphakathi, i-samente mortar iyagcinwa ngokubanzi kwaye umanyano lweqela le-samente mortar luyaphucuka. Ubukho be-polymer ephezulu elastiki buphucula ukuqina kunye nokuqina kwe-samente mortar. Umgaqo wokunyusa uxinzelelo lwemveliso kunye namandla oxinzelelo angasebenziyo ngolu hlobo lulandelayo: Xa amandla ekhutshwa, ii-micro-cracks ziya kulibazisa ixesha de uxinzelelo lwangaphakathi lwande ngenxa yokwanda kwe-ductility kunye nokuqina. Ukongeza koku, iindawo ze-polymer ezidibeneyo nazo zinefuthe lokuthintela kwii-micro-cracks ezidityaniswe zii-cracks. Ke ngoko, umgubo we-latex wendalo osasazekileyo unokunyusa uxinzelelo olungasebenziyo kunye noxinzelelo olungasebenziyo lwezinto ezikrwada. Ifilimu ye-polymer kwi-polymer modified material cement mortar yingozi ephambili kwi-samente eqinileyo. Ukusasazeka kwee-polymer powders ezisasazekayo kudlala enye indima ephambili kwiphepha, ekukuphucula ukunamathela kwezinto ezikrwada ezidibanayo.
Uninzi lweepowder zepolymer ezisasazekayo ezibonwa ngabantu ngokubanzi xa besakha zimhlophe njengobisi, nangona ezinye izithunzi zinokubonakala. Ulwakhiwo lwepowder yelatex esasazekayo luqulunqwe ikakhulu yisisombululo se-colloid kunye ne-resistant ye-polymer epoxy resin ephezulu (yangaphakathi neyangaphandle). Phakathi kwazo, i-resin ye-polymer epoxy ephezulu ikwindawo ephambili yee-particles ze-rubber powder kwaye yinxalenye ephambili yepowder yepolymer esasazekayo.
Umgubo wepolymer osasazekayo awudingi manzi empompini kwindawo yokugcina nasekuthuthweni, nto leyo enokonga iindleko zokuthutha zeemodyuli zokwakha ubunjineli kwaye yenze uthutho lube lula kwaye lukhawuleze. Umgubo welatex wendalo osasazekayo owenziwe ngumzi-mveliso wesamente unobomi obude kwaye ungagcinwa ixesha elide ngaphandle kokukhathazeka ngokuqandisa kubushushu obuphantsi kakhulu kunye nokugcinwa okulula. Ingxowa nganye yomgubo wepolymer osasazekayo incinci ngomthamo, ilula ngobunzima, kwaye kulula ukuyisebenzisa.
