ʻO ke ala hoʻāʻo no ka viscosity o ka pauka latex redispersible

I kēia manawa, ʻo nā pauka latex redispersible i hoʻohana nui ʻia ma ka honua, ʻo ia ka vinyl acetate a me ka ethylene copolymer pauda, ​​ethylene, vinyl chloride a me ka vinyl laurate ternary copolymer pauda, ​​vinyl acetate, ethylene a me ka momona momona vinyl ester ternary copolymer pauda. ʻO ka pauka, ʻo kēia mau pauka polymer redispersible ʻekolu i hoʻomalu i ka mākeke holoʻokoʻa, ʻoi aku ka vinyl acetate a me ka ethylene copolymer pauka VAC / E, e noho ana i kahi kūlana alakaʻi i ka honua honua a hōʻike i nā ʻano loea o ka pauka polymer redispersible. ʻO ia ka hopena ʻenehana maikaʻi loa e pili ana i ka ʻike loea me nā polymers i hoʻopili ʻia i ka hoʻololi ʻana i ka mortar:

1. ʻO ia kekahi o nā polymers i hoʻohana nui ʻia ma ka honua;

2. ʻO ka ʻike noi ma ke kahua o ke kūkulu ʻana ka mea nui loa;

3. Hiki iā ia ke hoʻokō i nā waiwai rheological i koi ʻia e ka mortar (ʻo ia hoʻi, ka mea e pono ai ke kūkulu ʻia);

4. ʻO ka resin polymer me nā monomers ʻē aʻe nā hiʻohiʻona o nā mea hoʻoheheʻe organik haʻahaʻa (VOC) a me ke kinoea hoʻonāukiuki haʻahaʻa;

5. Loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa UV maikaʻi, ke kūpaʻa wela maikaʻi a me ke kūpaʻa lōʻihi;

6. Kū'ē kiʻekiʻe i ka saponification;

7. Loaʻa iā ia ka laulā o ke aniani hoʻololi wela (Tg);

8. Loaʻa iā ia ka hoʻopaʻa piha piha ʻana, ka maʻalahi a me nā waiwai mechanical;

9. Loaʻa ka ʻike lōʻihi loa i ka hana kemika o ka hana ʻana i nā huahana kūpaʻa maikaʻi a me ka ʻike i ka mālama ʻana i ke kūpaʻa o ka mālama ʻana;

10. He mea maʻalahi loa ia e hui pū me ka colloid pale (polyvinyl alcohol) me ka hana kiʻekiʻe.

ʻO ke ala ʻike o ka ikaika hoʻopaʻa ʻana o ka pauka latex redispersible i ʻike ʻia i ke ʻano o ka hoʻoholo ʻana penei:

1. ʻO ka mua, e lawe i 5g o ka pauka latex redispersible a hoʻokomo i loko o ke kīʻaha ana aniani, e hoʻohui i 10g o ka wai maʻemaʻe a hoʻoulu i 2 mau minuke i hui like ʻia;

2. A laila, e kū ke kīʻaha ana hui ʻia no 3 mau minuke, a laila e hoʻoulu hou no 2 mau minuke;

3. A laila e hoʻopili i nā mea hoʻonā a pau i loko o ke kīʻaha ana ma luna o kahi pā aniani maʻemaʻe i kau ʻia ma ka ʻaoʻao;

4. E hoʻokomo i ka pā aniani i loko o ka DW100 haʻahaʻa wela kaiapuni simulation keʻena ho'āʻo;

5. ʻO ka hope, e kau ma lalo o ke kūlana simulation kaiapuni o 0 ° C no ka hola 1, e lawe i waho o ka pā aniani, e hoʻāʻo i ke kiʻi ʻoniʻoni ʻana, a helu i ka ikaika hoʻopaʻa maʻamau o ka pauka latex redispersible i hoʻohana ʻia e like me ke kiʻi ʻoniʻoni. .
