Zaj duab xis ntawmredispersiblepolymerhmoovRDPyog elastic thiab tawv, nyob rau hauv lub pob txha pob txha tsim los ntawm hydration ntawm cement mortar. Nyob nruab nrab ntawm cov khoom ntawm cov cement mortar, nws ua haujlwm zoo li kev sib koom ua ke, uas tuaj yeem dais siab deformation loads, txo qhov kev ntxhov siab, thiab txhim kho tensile thiab khoov tsis kam.
Redispersible polymer hmoov txhim kho kev cuam tshuam rau cov thermoplastic resins. Nws yog cov zaj duab xis mos coated rau ntawm qhov chaw ntawm cov tshuaj khib nyiab, thiab cov hmoov latex redispersible tuaj yeem nqus cov kev cuam tshuam ntawm sab nraud quab yuam, so tsis muaj kev puas tsuaj, yog li txhim kho qhov cuam tshuam ntawm cov tshuaj khib. Redispersible latex hmoov nce hydrophobicity, txo cov dej nqus, thiab tuaj yeem txhim kho microstructure ntawm cement mortar.
Nws cov polymer tsim ib qho kev sib txuas tsis tau thaum lub sij hawm cement hydration, ntxiv cov hmoov latex redispersible. Lub capillary hauv cov cement gel raug kaw los thaiv cov dej nqus dej, tiv thaiv kev nkag mus ntawm cov dej, thiab txhim kho impermeability. Redispersible polymer hmoov txhim kho kev puas tsuaj ua haujlwm ntev.
Redispersible latex hmoov yog tsuas yog siv nyob rau hauv qhuav cement mortar nyob rau hauv kev tsim kho kev lag luam, thiab yog ib qho tseem ceeb additive rau qhuav cement mortar. Lub luag haujlwm ntawm cov cement mortar qhuav yog qhov tseem ceeb, uas tuaj yeem txhim kho lub zog sib txuas thiab kev sib koom ua ke ntawm cov khoom, txhim kho elastic bending zog thiab flexural lub zog ntawm cov khoom, txhim kho lub khov-thaw tsis kam ntawm cov khoom, thiab txhim kho huab cua tsis kam, durability. thiab hnav tsis kam ntawm cov khoom siv. Txhim kho cov hydrophobicity ntawm cov khoom, txo cov dej nqus tus nqi, txhim kho kev ua haujlwm, txo tus nqi shrinkage ntawm cov khoom, thiab tiv thaiv kev tawg. , los txhim kho khoov thiab tensile kuj.
