E like me ka ratio like ʻole, ka hoʻohana ʻana oka pauka polymer redispersiblee hoololi i kamaloʻo hui ʻiaHiki iā ia ke hoʻomaikaʻi i ka ikaika paʻa me nā substrate like ʻole, a hoʻomaikaʻi i ka maʻalahi a me ka deformability o ka mortar, ka ikaika kulou, ke kūpaʻa ʻana, ka paʻakikī, ka ikaika paʻa a me ka paʻa, ka hiki ke mālama i ka wai a me ka hana.
He helu nui o nā ho'āʻo e hōʻike i ka nui oRDpaudaʻaʻole ʻoi aku ka maikaʻi. Ke haʻahaʻa loa ka ʻike o ka pauka RD, hoʻokani wale ia i kahi hopena plasticizing, akā ʻaʻole maopopo ka hopena hoʻonui. I ka manawa o ka nui oRD paudanui loa, emi ka ikaika. I ka manawa wale nō ka maʻi o ka pauka RD, ʻaʻole ia e hoʻonui wale i ka pale deformation, hoʻomaikaʻi i ka ikaika tensile a me ka ikaika paʻa, akā hoʻomaikaʻi pū i ka permeability a me ka pale ʻana. ʻO ka lakio o ka lime a me ke one, ka ratio o ka wai a me ka sima, ka gradation a me ke ʻano o ka aggregate, a me nā ʻano o ka aggregate e hopena hope loa i ka hana piha o ka huahana.
Ka mana oredispersiblelatexpaudaʻO ka ikaika o ka mortar hiki ke hoʻonui nui ʻia ka ikaika tensile a me ka flexural ikaika o ka mortar ma hope o ka hoʻohui ʻana oredispersiblepolimerpauda,akā, ʻaʻole i hoʻomaikaʻi nui ʻia ka ikaika compressive a i ʻole ka emi ʻana. Ma muli o ka hopena paʻakikī oredispersiblepolimerpauda, ua hoʻomaikaʻi ʻia ka ikaika tensile kūloko a me ka interfacial bonding tensile ikaika o ka mortar, a ua hoʻomaikaʻi nui ʻia ka ikaika tensile paʻa ma waena o ka mortar a me ka substrate.
ʻO ka haʻihaʻi ʻana o nā mea brittle ma muli o ka hiki ʻole o ka tensile, ke ʻoi aku ke koʻikoʻi o ke koʻikoʻi ma mua o kona waiwai ponoʻī ponoʻī, e hiki mai ka haki. No laila, ʻo ka loaʻa ʻana o ka waiwai tensile kiʻekiʻe he kūlana kūpono no ke kūʻē ʻana i ka haki.
Hōʻike nā hopena i ka piʻi mua ʻana o ka ikaika tensile o ka momi sima i hoʻololi ʻia i ka polymer a laila e emi me ka piʻi ʻana o ka ratio ciment-cement, ʻo ia ka mea e hōʻike ana he ʻano hui maikaʻi. ʻO ke kumu o ka emi ʻana ma muli o ka hoʻohui ʻana o ka nuiredispersible emulsion paudae alakaʻi ana i ka hoʻokomo ʻana i nā ʻōhū he nui loa, e hopena i kahi ʻano i lalo o ka ikaika compressive. No laila, pono e hoʻomaikaʻi ʻia ka ikaika compressive ma ka hoʻoponopono ʻana i ka ratio o ka lime i ke one, ka wai i ka sima, ka hoʻohui ʻana a me ke ʻano aggregate. Hiki ke hoʻokō ʻia ka hoʻomaikaʻi ʻana i ka ikaika tensile, ka ikaika flexural, ka maʻalahi, ka pale ʻana a me ka hydrophobicity ma ka hoʻohui ʻana.redispersiblelatexpauda, akā ʻoi aku ka nui o ka hoʻohui ʻana, ʻoi aku ka maikaʻi. Ke haʻahaʻa loa ka ʻike o ka pauka rubber, hoʻokani wale ia i kekahi hopena plasticizing, akā ʻaʻole maopopo ka hopena hoʻonui. Ke nui loa ka nui o ka pauda redispersible, e emi ana ka ikaika. Aia wale ka maʻiʻo oredispersiblepaudahe haʻahaʻa, ʻaʻole ia e hoʻonui wale i ke kūpaʻa deformation, ka ikaika tensile a me ka ikaika paʻa, akā hoʻomaikaʻi hoʻi i ka permeability a me ka pale ʻana. ʻO ka lakio o ka lime a me ke one, ka ratio o ka wai a me ka sima, ka gradation a me ke ʻano o ka aggregate, a me nā ʻano o ka aggregate e hopena hope loa i ka hana piha o ka huahana.
