Firimu reredispersiblepolymerupfuRDPiri elastic uye yakaoma, muskeleton yakaoma inoumbwa nekuyerera kwesamende dhaka. Pakati pezvimedu zvesamende dhaka, inoshanda senge mubatanidzwa unofambiswa, unogona kutakura mitoro yakakwira deformation, kuderedza kushushikana, uye kunatsiridza kusimba uye kukotama kuramba.
Redispersible polymer poda inovandudza kupikisa kwe thermoplastic resins. Ifirimu rakapfava rakaputirwa pamusoro pezvimedu zvedhaka, uye redispersible latex poda inogona kutora kukanganiswa kwemasimba ekunze, kuzorora pasina kukuvadzwa, nekudaro ichivandudza kupikisa kwedhaka. Redispersible latex poda inowedzera hydrophobicity, inoderedza kunyura kwemvura, uye inogona kuvandudza microstructure yesamende dhaka.
Iyo polymer yayo inoumba network isingadzokerike panguva yesamende hydration, ichiwedzera redispersible latex poda. Iyo capillary mune simenti gel yakavharwa kuvharira kubatwa kwemvura, kudzivirira kupinda kwemvura, uye kunatsiridza kusamira. Redispersible polymer poda inovandudza abrasion kuramba kusimba.
Redispersible latex poda inonyanya kushandiswa mune yakaoma simende dhaka muindasitiri yekuvaka, uye yakakosha yekuwedzera kune yakaoma simende dhaka. Basa rekuoma simende dhaka rakakosha, iro rinogona kuvandudza simba rekubatanidza uye kubatana kwechinhu, kuvandudza elastic kukotama simba uye kuchinjika simba rechinhu, kunatsiridza kutonhora-kunyunguduka kuramba kwezvinhu, uye kugadzirisa mamiriro ekunze, kusimba. uye kupfeka kupikisa kwezvinhu. Kuvandudza iyo hydrophobicity yezvinhu, kuderedza chiyero chekunyura kwemvura, kuvandudza kushanda, kuderedza shrinkage rate yechinhu, uye zvinobudirira kudzivirira kuputika. , kunatsiridza kukotama uye kusimba kuramba.
