Redispersible latex poda ine yakanaka redispersibility, redisperses mu emulsion kana yasangana nemvura, uye makemikari ayo maitiro anenge akafanana nekutanga emulsion.Kuwedzera dispersible emulsion latex powder kune simenti kana gypsum-based dry powder yakagadzirira-yakavhenganiswa dhaka inogona kuvandudza zvinhu zvakasiyana-siyana zvedhaka, zvakadai se: kuvandudza kuwirirana nekubatana kwezvinhu;kuderedza kunyura kwemvura uye elastic modulus yezvinhu;kuwedzera simba rezvinhu zveFlexural, kupikisa kwesimba, kupfeka kuramba uye kusimba;kunatsiridza mashandiro ekuvaka kwezvinhu, nezvimwe.
Kuwedzera latex poda kune simende dhaka inogadzira yakanyanya kuchinjika uye elastic polymer network firimu, iyo inozovandudza zvakanyanya kushanda kwedhaka, kunyanya kusimba kwedhaka kuchavandudzwa zvakanyanya.Kana simba rekunze rinoshandiswa, nekuda kwekuvandudzwa kwekubatana kwese kwedhaka uye kunyorova kwepolymer, kuitika kwe micro-cracks ichagadziriswa kana kuderera.Kuburikidza nepesvedzero ye latex powder content pamusoro pesimba remafuta ekupisa dhaka, zvinowanikwa kuti simba rehutano rehutano hwehutu hunopisa hunowedzera nekuwedzera kwe latex powder content;iyo flexural simba uye simba rekumanikidzika rine imwe dhigirii nekuwedzera kwe latex powder content.Iyo dhigirii yekuderera, asi ichiri kusangana nezvinodiwa zvemadziro ekunze kupera.
Iyo simende dhaka yakasanganiswa nelatex poda, iyo 28d yekubatanidza simba inowedzera nekuwedzera kwelatex hupfu hwemukati.Nekuwedzera kwe latex poda yemukati, kugona kwekubatanidza kwesamende dhaka uye yekare simende kongiri pamusoro inovandudzwa, iyo inova nechokwadi chayo yakasarudzika mabhenefiti ekugadzirisa simende kongiri pavement uye zvimwe zvimiro.Uyezve, chiyero chekupeta chedhaka chinowedzera nekuwedzera kwe latex powder content, uye kushanduka kwepasi pevhu kunovandudza.Panguva imwecheteyo, nekuwedzera kwe latex powder content, elastic modulus yevhu inoderera kutanga uye inowedzera.Pakazara, nekuwedzera kweash accumulation ratio, iyo elastic modulus uye deformation modulus yedhaka yakadzikira pane iyo yakajairika dhaka.
Chidzidzo chacho chakawana kuti nekuwedzera kwe latex powder content, kuwirirana uye kuchengetwa kwemvura kwedhaka kwakanyatsogadziriswa, uye kushanda kwekushanda kwakagadziridzwa.Kana huwandu hwe latex powder hunosvika 2.5%, kushanda kwevhu kunogona kuzadzisa zvizere zvinodiwa zvekuvaka.Nhamba ye latex powder haifaniri kunge yakanyanyisa, iyo haingoiti chete EPS insulation mortar zvakare viscous uye ine yakaderera fluidity, iyo isingagadzirisi kuvaka, asiwo inowedzera mari yedhaka.
