Redispersible latex poda inovandudza kushanduka uye kutsemuka kuramba kwedhaka

Mushure mekuwedzera redispersible latex poda mudhaka, iyo fold-compression ratio uye tension-compression ratio yedhaka inovandudzwa zvakanyanya, izvo zvinoratidza kuti brittleness yedhaka inodzikiswa zvakanyanya uye kuoma kwacho kunovandudzwa zvakanyanya, kuitira kuti kutsemuka kurambe kuripo. dhaka rakavandudzwa.

Iyo yakatemerwazve latex hupfu inorasa mvura mudhaka kuti iite firimu, iro risingangozadzi kukanganisa uye pores mudombo resimende, asiwo rinogadzira simende hydration zvigadzirwa uye aggregates chisungo pamwe chete kuti aumbe interpenetrating network yemapolima. Iyo elastic modulus yedhaka yakaderera kupfuura iyo yedhaka, saka brittleness yevhu inoderedzwa. Iko kuchinjika kwedhaka kunowedzera iyo yakanyanya deformation muganho kana dhaka rakuvadzwa, uye inogona kutora simba rinodiwa pakuwedzera kwekuremara uye madiki-akatsemuka kusvika pamwero mukuru, kuitira kuti dhaka rikwanise kumira kushushikana kukuru kusati kwakundikana. Pamusoro pezvo, iyo firimu yepolymer ine yekuzvitambanudza, uye iyo firimu yepolymer ine basa rekubatanidza rinofambiswa mune yakaomarara skeleton yakaumbwa mudhaka mushure mesamende hydration, iyo inogona kuve nechokwadi kusimba uye kusimba kweakaomarara skeleton. Pamusoro pefirimu yepolymer yakaumbwa pamusoro pezvimedu zvevhu ine pores, uye pamusoro pemapores izere nedhaka, kuitira kuti kushushikana kwekunetseka kuderedzwa, uye kuchazorora pasina kukuvara pasi pechiito chekunze kwesimba. Inovandudza kushanduka uye elasticity yedhaka.
