RDP no ka hamo maloo maloo

ʻO ka mortar maloʻo i hui pū ʻia he ʻano o ka hui pū ʻana a me ka pauka o nā mea hoʻohui maikaʻi a me nā mea hoʻoheheʻe inorganic, mea hoʻopaʻa wai mānoanoa, mea hoʻohaʻahaʻa wai, anti-cracking agent, defoaming agent a me nā mea hoʻohui ʻē aʻe i hui like ʻia i kekahi ʻāpana. Lawe ʻia ia i ka pūnaewele e ka pahu pahu pahu kūikawā a i ʻole ʻeke pepa wai ʻole i hoʻopaʻa ʻia, a hui pū ʻia me ka wai. I kēia manawa ma kahi o ka sima a me ke one i loko o kahi nui o ka mortar maloʻo i hui pū ʻia, ʻo ka nui o nā mea ʻē aʻe he redispersible redispersible.polimer pauda RDP. Ma muli o kona kumukūʻai kiʻekiʻe a me ka mana nui i nā waiwai mortar, ʻo ia ka mea e nānā ai ka poʻe. Ka mana o redispersiblepolimer pauda RDPua kūkākūkā ʻia ma kēia pepa i nā waiwai o ka moka.

1 Hana Hoao

I mea e hoʻoholo ai i ka mana o redispersiblepolimer pauda RDPmaʻiʻo e pili ana i nā waiwai mortar polymer, Ua hoʻolālā ʻia kekahi mau pūʻulu o ka hoʻohālikelike ʻia e ke ʻano hoʻāʻo orthogonal a hoʻāʻo ʻia e like me dbjoi-63-2002, ke kūlana Inspection Standard o ka polymer Mortar no ka insulation waho o ka pā o waho, e hoʻoholo i ka mana o ka mortar polymer ma ka tensile ikaika paʻa, ikaika hoʻopaʻa kuʻi compressive a me ka ikaika compressive, ikaika flexural a me ka ratio flexural o ka polimer mortar ma ke kumu kaʻa.

ʻO ka mea nui maka he P-04 2.5-pu silicon sima; RE5044 a me R1551Z hiki ke hoʻopuehu hou a hoʻopuehu hou i ka pauka emulsion; 70-140 mesh quartz one; Nā mea hoʻohui ʻē aʻe.

2 Ka hopena o ka redispersiblepolimer pauda RDPma na waiwai o ka polimer mortar

2.1 Nā waiwai pili paʻa uʻi a me ka hoʻopaʻa ʻana

Me ka hoonui o redispersiblepolimer pauda RDPmaʻiʻo, hoʻonui ʻia ka ikaika paʻa tensile a me ka ikaika o ka paʻa ʻāwili compressive o ka momi polymer a me ka mīkini sima, a ke neʻe nei nā ʻāpana ʻelima i luna e like me ka piʻi ʻana o ka maʻiʻo sima. ʻO nā helu kūpono a pau i kaupaona ʻia, akā hiki ke hoʻopuehu ʻia ka helu ʻana i ka emulsion pauda ma ke ʻano o ka mana o ka hana ʻana o ka mīkini sima hana hiki ke ʻike me ka hoʻonui ʻana o ka hoʻopuehu ʻia emulsion pauka maʻiʻo ma ka hoʻopaʻa ʻana i ka ikaika o ka lepo lepo, polymer mortar compressive shear ikaika. ka ulu laina laina, ke au holoʻokoʻa no ka hoʻonui 1% e hoʻopuehupolimer pauda RDP, ua hoʻonui ʻia ka ikaika hoʻopaʻa ʻana e 0.2 MPa, Ua hoʻonui ʻia ka ikaika hoʻopaʻa hoʻopaʻa hoʻopaʻa ʻana i ka 0.45MPA.

2.2 Nā mea hoʻopili/piʻo ʻana o ka hamo ponoʻī

Me ka hoʻonui o ka maʻiʻo o redispersiblepolimer pauda RDP, ka ikaika compressive a me ka flexural ikaika o ka polymer mortar emi, e hōʻike ana i ka polymer i ka hopena i ka hydration o ka sima. FIG. Hōʻike ka 4 i ka mana o ka redispersiblepolimer pauda RDPmaʻiʻo e pili ana i ka lākiō hoʻopaʻa a me ka pelu ʻana o ka mortar polymer. , me ka hoʻonui ʻana o ka mea i hoʻokaʻawale ʻiapolimer pauda RDP, ke emi iho nei ka lakio pa'i pono'ī o ka momi polymer, e hōʻike ana i ka hoʻomaikaʻi ʻana o ka polymer i ka paʻakikī o ka mortar. Ka mana o ka maʻiʻo o redispersiblepolimer pauda RDPma ka hana ana o ka polimer mortar hiki ke helu helu ia e ka awelika kaumaha o kela a me keia wahi correlation. Me ka hoʻonui o ka maʻiʻo o redispersiblepolimer pauda RDP, ka ikaika compressive, flexural strength and flexural ratio of polymer mortar e hōʻike ana i ka laina emi iho. Ka ikaika compressive, flexural ikaika a me ka flexural ratio o redispersiblepolimer pauda RDPua emi iho e 1.21 MPa, 0.14MPa a me 0.18 no 1%. Hiki ke ʻike ʻia ma muli o ka piʻi ʻana o ka nui o ka redispersiblepolimer pauda RDP, ua hoʻomaikaʻi ʻia ka maʻalahi o ka mortar.

2.3 Ka helu helu o ka mana o ka lakio sima-sand ma na waiwai o ka polimer mortar

I ka polimer mortar, ka sima-sand ratio a redispersiblepolimer pauda RDPmaʻiʻo pāʻani pololei me kekahi i kekahi, no laila, pono e kūkākūkā i ka mana o ka sima-sand ratio kaawale. E like me ka orthogonal hoʻokolohua ikepili hana kaʻina hana e okoa like 'ole e like me nā loli, hiki ke hoʻopuehu me kapolimer pauda RDPʻO ka maʻiʻo ma ke ʻano he kumu mau ka hoʻohālikelike ʻana i ka hopena o ka hoʻololi ʻana i ka mortar quantitative figure, hiki ke ʻike ʻia me ka piʻi ʻana o ka hoʻohālikelike ʻana i ka hana o ka mortar sima polymer mortar a me ka hana ʻana o ka mortar polymer ponoʻī ke emi iho nei ke ʻano, ʻo ke ʻano maʻamau ʻo ia ka ʻO ka ikaika paʻa tensile o ka momi polimer i ka momi sima e hoʻemi ʻia e 0.12MPa, e emi ana ka ikaika hoʻopaʻa shear compressive e 0.37MPa, ke emi nei ka ikaika compressive o ka mortar polymer e 4.14MPa, ke emi nei ka ikaika flexural e 0.72MPa, a ke emi nei ka ratio flexural e 0.270 me kela me keia pii ana o ka ratio ciment-sand.

3 Ka hopena o ka redispersiblepolimer pauda RDPma ka tensile paʻa ma waena o polymer mortar a me ka EPS foam polystyrene papa DB JoI-63-2002 maʻamau manaʻo i ka hoʻopaʻa ʻana o ka mīkini polimer i ka pahu sima a me ka papa EPS he kue.

Pono ka mea mua e paʻa i ka mortar polymer, aʻo ka mea hope e koi i kona maʻalahi e kiʻekiʻe, akā e noʻonoʻo ana i ka ʻenehana insulation waho e hoʻopaʻa i ka pā paʻa a me ka papa EPS maʻalahi, i ka manawa like e hōʻoia ai ʻaʻole kiʻekiʻe ke kumukūʻai. No laila, ka mana o ka maʻiʻo o redispersiblepolimer pauda RDPma ka waiwai ho'opa'a ma'alahi o ka mortar polymer i helu 'ia i mea 'oko'a no ka ho'oikaika 'ana i kona ko'iko'i.

4Ka hopena o nā ʻano redispersiblepolimer pauda RDPma ka ikaika pili o ka papa EPS

ʻO R5, C1, P23 nā ʻano mea hiki ke hoʻopau hou ʻiapolimer pauda RDPua koho ʻia mai nā ʻāina ʻē. Taiwan D2,D4 2 ano; S1 hale, S2 2 ʻano 7 ʻano; ʻO ka papa polystyrene i hana ʻia ma Beijing 18kg/ laina EPS papa. E like me ka maʻamau dbJ01-63-2002, hiki ke hoʻokaʻawale ʻia ka pilina pilipolimer pauda RDPHiki i ka papa EPS ke hoʻokō i nā koi paʻa paʻa paʻa paʻa o ka polymer mortar i ka manawa like.
