Mumortar, upfu hwepolymer hunonyungudika hunogona kuvandudza hunhu hwekugadzira upfu hwerabha, kuvandudza kuyerera kweupfu hwerabha, kuvandudza thixotropy uye kuramba kudonha, kuvandudza simba rekubatana kweupfu hwerabha, kuvandudza kunyungudika kwemvura, uye kuwedzera nguva iyo inovhurwa kune nyika yekunze. Mushure mekunge mortar yesimende yaoma uye yaoma, inogona kuwedzera simba rekudzvanya, kuwedzera simba rekudhonza, kuderedza elastic mold, uye kuvandudza hunyanzvi. Upfu hwepolymer hunonyungudika hune kunamira kwakanaka kwefirimu, uye kushandiswa kwahwo kunogona kuonekwa mumapurojekiti ekuvaka nekushongedza.
Firimu re latex resin rabha ine chimiro chinodhonza chega, chinogona kusunungura simba rinotsigira pajoinhi ne simende mortar anchor. Zvichienderana nesimba iri remukati, simende yesimbi inochengetwa kazhinji uye kubatana kwechikwata che simende mortar kunovandudzwa. Kuvapo kwepolymer yakakwira inonatsa kunatsiridza ductility uye ductility ye simende mortar. Nheyo yekuwedzera goho rekumanikidzwa uye simba rekumanikidzwa risingashande ndeiyi inotevera: Kana simba raburitswa, micro-cracks inononotsa nguva kusvika in-situ stress yawedzera nekuda kwekuwedzera ductility uye ductility. Pamusoro peizvi, nzvimbo dze polymer dzakasanganiswa dzinewo mhedzisiro yekudzivirira pa micro-cracks dzakasanganiswa ne cracks. Naizvozvo, dispersed natural latex powder inogona kuwedzera kushaya simba uye kushaya simba kwezvinhu zvakabikwa. Firimu re polymer mu polymer modified material cement mortar injodzi huru kune simende yakaoma smelt mortar. Kupararira kwe polymer powders dzinopararira kunoita rimwe basa rinotungamira papeji, iro nderekuvandudza kunamira kwezvinhu zvakabikwa pakubata.
Ruzhinji rwemapoda epolymer anopararira anowanzoonekwa nevanhu mukugadzirwa kwawo machena semukaka, kunyange hazvo mamwe mavara angaonekwa. Muumbirwo wepoda yelatex inopararira zvakare unonyanya kuumbwa ne-polymer epoxy resin ine simba rekuchengetedza (mukati nekunze) colloid yekugadzirisa uye resistance agent. Pakati pawo, poda yepolymer epoxy ine simba guru iri panzvimbo yakakosha yezvikamu zverabha uye ndiyo chinhu chikuru chepoda yepolymer inopararira.
Upfu hwepolymer hunopararira haudi mvura yepombi pakuchengetera nekutakura, izvo zvinogona kuchengetedza mari yekufambisa yekuvaka mainjiniya uye kuita kuti kutakurwa kuve nyore uye nekukurumidza. Upfu hwelatex hunogona kunyungudika hunobva kufekitori yesimbi inonyungudika hunogara kwenguva refu uye hunogona kuchengetwa kwenguva yakareba pasina kunetseka nezvekutonhora kwakanyanya uye kuchengetwa kuri nyore. Bhegi rega rega reupfu hwepolymer hunopararira hudiki, huremu hwakareruka, uye huri nyore kushandisa.
