Pehea e hoʻāʻo ai i ka pauka polymer redispersible RDP?

ʻO ke ʻano hoʻāʻo no nā waiwai a me ka viscosity o ka pauka polymer redispersible RDP, ua hoʻohana nui ʻia ke ao holoʻokoʻa e hoʻopuehu i ka pauka polymer RDP me ka vinyl acetate a me ka ethylene copolymerized emulsion pauka, ethylene a me ka vinyl chloride a me ka lauric acid vinyl ester ternary copolymer pauka, vinyl acetate a me ethylene a me nā momona momona ʻekolu polymer ester diterna. ʻO ka mākeke holoʻokoʻa, ʻoi aku ka vinyl acetate a me ka ethylene copolymer pauka VAC / E, Noho ia i kahi kūlana alakaʻi i ka honua honua a hōʻike i nā ʻano loea o ka redispersible polymer powder RDP.

ʻO ka pauka polymer hiki ke hoʻokuʻu ʻiaLoaʻa i ka RDP ka ikaika paʻa koʻikoʻi, hoʻomaikaʻi i ka maʻalahi o ka mortar a ʻoi aku ka lōʻihi o ka wehe ʻana, hāʻawi i ka mortar maikaʻi loa i ke kūpaʻa alkaline, hoʻomaikaʻi i ka adhesion o ka mortar adhesion, flexural strength, waterproof, plasticity, wear resistance and construction, i ka flexible anti-crack mortar i ʻoi aku ka ikaika.

Mai ka ʻike loea o ka polymer i hoʻololi ʻia e ka mortar, ʻoi aku ka maikaʻi o ka ʻenehana loea:

1, ʻo RDP kekahi o nā polymers i hoʻohana nui ʻia ma ka honua.
2, Ka ʻike noiʻi nui ma ke kahua o ka hoʻolālā;

3, hiki ke hoʻokō i nā koi o ka mortar rheological waiwai (ʻo ia hoʻi, ke kūkulu pono ʻia);

4, me kekahi monomer polymer resin he haʻahaʻa organik volatile mea (VOC) a haʻahaʻa irritant kinoea 'ano;

5, me ke kūpaʻa maikaʻi o ka uv a me ke kūpaʻa wela maikaʻi a me ke kūpaʻa lōʻihi;

6, me ke kiʻekiʻe saponification kū'ē;

7, me ka laulā aniani aniani ākea (Tg);

8, me ka hoʻopaʻa paʻa piha maikaʻi loa, ka maʻalahi a me nā waiwai mechanical;

9, hana maʻalahi a like o ka colloid pale (polyvinyl alcohol) hui pū.

ʻO ke ala ʻike no ka ikaika adhesive o ka pauka polymer redispersible RDP e hōʻike ʻia e nā ʻano hoʻoholo aʻe:

1, e lawe mua i ka pauka polymer redispersible RDP 5g i loko o ke kīʻaha ana aniani, e hoʻohui i 10g wai maʻemaʻe a hoʻoulu no 2min, e hui like;

2. E hoʻonoho i ke kīʻaha ana hui ʻia no 3min a hoʻoulu hou no 2min;

3. E hamo i ka hoʻonā a pau i loko o ke kīʻaha ana ma luna o ka pā aniani maʻemaʻe;

4, hoʻokomo i ka pā aniani i DW100 haʻahaʻa haʻahaʻa haʻahaʻa kaiapuni simulation pahu ho'āʻo;

5, hoʻokomo hope i loko o 0 ° C kaiapuni simulation kūlana no 1 hola, lawe i ke aniani pā, ho'āʻo i ka kiʻiʻoniʻoni rate rate, e like me ke kiʻiʻoniʻoni rate huli ana o redispersible polymer pauda RDP i ka hoʻohana 'ana i ka maʻamau hoʻopaʻa ikaika.
