I-latex powder edibeneyo i-redispersible i-redispersibility enhle, iphinda iphinde ibe yi-emulsion xa idibene namanzi, kwaye iimpawu zayo zeekhemikhali ziphantse zifana ne-emulsion yokuqala. Ukongeza i-emulsion edibeneyo ye-latex powder kwi-samente okanye i-gypsum-based powder eyomileyo exutywe ngodaka inokuphucula iimpawu ezahlukeneyo zodaka, ezifana: nokuphucula ukudibanisa kunye nokudibanisa kwezinto; ukunciphisa ukufunxa kwamanzi kunye ne-elastic modulus yezinto eziphathekayo; ukuqinisa amandla e-Flexural, ukuxhathisa impembelelo, ukuxhathisa ukunxiba kunye nokuqina; ukuphucula ukusebenza kokwakhiwa kwezinto, njl.
Ukongeza i-latex powder kwi-cement mortar iya kwenza ifilimu yenethiwekhi ye-polymer eguquguqukayo kakhulu kunye ne-elastic, eya kuphucula kakhulu ukusebenza kodaka, ngakumbi amandla okuqina omdaka aya kuphuculwa kakhulu. Xa kusetyenziswe amandla angaphandle, ngenxa yokuphuculwa kokubambisana okupheleleyo komdaka kunye ne-elasticity ethambileyo yepolymer, ukuvela kwe-micro-cracks kuya kulungiswa okanye kuncitshiswe. Ngempembelelo yomxholo we-latex powder kumandla omdaka wokufakelwa kwe-thermal, kufunyenwe ukuba amandla e-tensile bond of thermal insulation mortar ayanda ngokunyuka komxholo we-latex powder; amandla okuguquguquka kunye namandla oxinzelelo aneqondo elithile kunye nokunyuka komxholo we-latex powder. Iqondo lokuhla, kodwa lihlangabezana neemfuno zokuphela kodonga lwangaphandle.
Udaka lwesamente oluxutywe kunye ne-latex powder, amandla ayo okudibanisa i-28d ayanda ngokunyuka komxholo we-latex powder. Ngokunyuka komxholo we-latex powder, ukukwazi ukudibanisa udaka lwesamente kunye nomphezulu wekhonkrithi endala yesamente iyaphuculwa, eqinisekisa iingenelo zayo ezizodwa zokulungisa i-pavement yekhonkrithi yesamente kunye nezinye izakhiwo. Ngaphezu koko, umlinganiselo wokugotywa kodaka uyanda ngokunyuka komxholo we-latex powder, kwaye ukuguquguquka kodaka lomphezulu kuphucula. Ngexesha elifanayo, ngokunyuka komxholo we-latex powder, i-modulus elastic yodaka iyancipha kuqala kwaye inyuke. Lilonke, ngokunyuka komlinganiselo wokuqokelelwa kothuthu, i-elastic modulus kunye ne-deformation modulus yodaka ziphantsi kunezo zodaka oluqhelekileyo.
Uphononongo lufumene ukuba ngokunyuka komxholo we-latex powder, ukudibanisa kunye nokugcinwa kwamanzi omdaka kwaphuculwa kakhulu, kwaye ukusebenza komsebenzi kwandiswa. Xa inani le-latex powder lifikelela kwi-2.5%, ukusebenza komdaka kunokwanelisa ngokupheleleyo iimfuno zokwakha. Isixa se-latex powder ayifuni ukuba siphezulu kakhulu, engenzi nje kuphela ukuba i-EPS i-insulation mortar ibe ne-viscous kwaye ine-fluidity ephantsi, engabangeli ukwakhiwa, kodwa inyusa iindleko zodaka.
