ʻO ka ʻokoʻa ma waena o ka pauka polymer redispersible a me ka pauka resin

I nā makahiki i hala iho nei, ua ʻike ʻia ka nui o ka pauka resin polymer, ka pauka polymer kūpaʻa wai ikaika a me nā pauka polymer ʻē aʻe ma ka mākeke e pani i ka emulsion VAE kuʻuna (vinyl acetate-ethylene copolymer), i hoʻomaloʻo ʻia a maloʻo. i hana ʻia me ka pauka polymer recyclable.ʻO ka pauka polymer i hoʻopuehu ʻia, no laila he aha ka ʻokoʻa ma waena o ka pauka resin a me ka pauka polymer redispersible, hiki anei i ka pauka resin ke hoʻololi i ka pauka polymer redispersible?E alakaʻi ʻo Mortar Technology Center iā ʻoe e nānā pōkole i ka ʻokoʻa ma waena o nā mea ʻelua no kāu kuhikuhi:

(1), redispersible polymer pauka

I kēia manawa, ʻo nā pauka polymer redispersible i hoʻohana nui ʻia i ka honua: vinyl acetate a me ethylene copolymer pauka (VAC / E), ethylene, vinyl chloride a me vinyl laurate ternary copolymer pauka (E / VC / VL), acetic acid Vinyl ester, ethylene a ʻoi aku ka nui o ka momona momona vinyl ester ternary copolymer pauka (VAC/E/VeoVa), ʻo kēia mau pauka polymer redispersible ʻekolu e hoʻomalu i ka mākeke holoʻokoʻa, ʻoi aku ka vinyl acetate a me ka ethylene copolymer pauda VAC/EE, noho i kahi kūlana kiʻekiʻe ma ke kahua honua a hōʻike i ka ʻenehana. nā hiʻohiʻona 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.

(2), pauda resin

ʻO ka hapa nui o ka pauka polymer "resin" ma ka mākeke ka mea kemika DBP.Hiki iā ʻoe ke nānā i ka pōʻino o kēia mea kemika, e pili ana i ka hana moe kāne.ʻO ka nui o kēia ʻano o ka pauka polymer i ahu ʻia i loko o ka hale kūʻai a ma ka hale hana, a he mau volatility.Ma ka mākeke ʻo Beijing, i kaulana no ka nui o ka "polymer powder", aia i kēia manawa he "polymer powder" i hoʻomoʻa ʻia i loko o nā solvents me nā inoa like ʻole: ikaika kiʻekiʻe wai-kūpaʻa polymer pauka, resin polymer pauka, etc. Nā hiʻohiʻona maʻamau:

1. ʻAʻole hiki ke hoʻopuehu ʻia, pulu kekahi, manaʻo kekahi poʻe flocculent (he mea porous e like me sepiolite), keʻokeʻo a maloʻo iki kekahi akā honi ʻino;

2. Honi loa ia;

3. Ua hoʻohui ʻia kekahi mau kala, a ʻo nā waihoʻoluʻu e kū nei i kēia manawa he keʻokeʻo, melemele, hina, ʻeleʻele, ʻulaʻula, etc.

4. He liʻiliʻi loa ka nui o ka hoʻohui, a ʻo ka nui o ka hoʻohui no hoʻokahi tona he 5-12 kg;

5. He mea kupanaha ka ikaika mua.ʻAʻohe ikaika o ka sima i nā lā ʻekolu, a hiki ke ʻino a paʻa ka papa insulation;

6. Ua ʻōlelo ʻia ʻaʻole pono ka papa XPS i kahi mea kikowaena interface.

Ma o nā laʻana i loaʻa i kēia manawa, hiki ke hoʻoholo ʻia he resin solvent-based adsorbed e nā mea porous māmā, akā makemake ka mea kūʻai aku e pale i ka huaʻōlelo "solvent", no laila ua kapa ʻia ʻo "polymer powder".

hemahema:

1. He pilikia nui ka pale ʻana i ka ea o ka solvent.I ka lā, e mahuka i loko o ka manawa pōkole.ʻOiai ʻaʻole ia i ka lā, e hoʻoheheʻe ʻia ka mea hoʻopaʻa paʻa ma muli o ke kūkulu ʻana o ka lua;

2. ʻO ke kūpaʻa ʻana o ka wā kahiko, ʻaʻole kūpaʻa ka wela, ʻike nā mea a pau i kēia;

3. No ka hoʻopau ʻana o ka mīkini hoʻopaʻa ʻana i ke kikowaena o ka papa insulation, ma ka mea ʻē aʻe, hoʻopau ia i ka pilina pili.Inā loaʻa kahi pilikia me kēia pilikia ma ka pae hope, e make ka hopena;

4. ʻAʻohe mua o ka noi ma nā ʻāina ʻē.Me ka ʻike kemika maʻamau ma waho, hiki ʻole ke ʻike ʻole i kēia mea.

hōʻuluʻulu manaʻo:

ʻO ka pauka polymer redispersible:

1. ʻO ka huahana polymer powder redispersible he wai-soluble redispersible pauka, he copolymer o ka ethylene a me ka vinyl acetate, me ka polyvinyl alcohol e like me ka colloid pale.

2. VAE redispersible polymer pauda loaʻa nā waiwai hana kiʻiʻoniʻoni, 50% aqueous solution e hana i ka emulsion, a hana i kahi kiʻiʻoniʻoni-like plastik ma hope o ke kau ʻana ma ke aniani no 24 mau hola.

3. ʻO ke kiʻiʻoniʻoni i hoʻokumu ʻia he mau mea maʻalahi a me ka pale wai.Hiki ke hōʻea i ka pae aupuni.

4. He kiʻekiʻe ka hana ʻana o ka pauka polymer redispersible: loaʻa iā ia ka mana hoʻopaʻa kiʻekiʻe, ka hana kūʻokoʻa a me ka hana ʻole o ka wai, ka ikaika hoʻopaʻa maikaʻi, hāʻawi i ka mortar me ke kūpaʻa alkali maikaʻi loa, a hiki ke hoʻomaikaʻi i ka adhesion a me ka ikaika flexural o ka mortar Ma waho aʻe o ka plasticity, hoʻopaʻa kūʻē. a me ke kūkulu ʻana, ʻoi aku ka ikaika o ka maʻalahi i ka mortar anti-cracking.

ʻO ka pauka resini:

1. ʻO Resin polymer pauda he ʻano hou o ka hoʻololi huahana no ka polymer, resin, polymer molecular kiʻekiʻe, a me ka pauka polymer lepo maikaʻi.

2. ʻO ka pauka Resin polymer ka lōʻihi loa, ke kūpaʻa ʻana, ka puʻupuʻu maikaʻi ʻole, manaʻo kekahi i ka flocculent (pono he mea porous e like me sepiolite), a he mau pauka keʻokeʻo (akā, he ʻala like me ke ʻaila).

3. ʻO kekahi mau pauka resin he mea ʻino i ka papa, a ʻaʻole kūpono ka wai wai.

4. ʻO ke kū ʻana o ka ea a me ke kū ʻana o ka wai o ka pauka resin polymer he haʻahaʻa ma mua o ka pauka polymer.He pilikia nui ka pale ʻana i ka wā.I ka lā, e mahuka i loko o ka manawa pōkole.ʻOiai ʻaʻole ia i ka lā, e hoʻopili ʻia ka mea hoʻopili No ka mea he hana lua ia, e hoʻoheheʻe wikiwiki ʻia.

5. ʻAʻohe moldability ka pauka polymer resin, e waiho wale i ka loli.Wahi a nā kūlana hoʻāʻo no ka mortar insulation pā waho, ʻo ka nui o ka pōʻino o ka papa polystyrene e hoʻokō i ka maʻamau.ʻAʻole kūpono nā hōʻailona ʻē aʻe.

6. Hiki ke hoʻohana wale ʻia ka pauka resin polymer no ka hoʻopaʻa ʻana i nā papa polystyrene, ʻaʻole hiki ke hoʻohana ʻia no ka hoʻopaʻa ʻana i nā pahu vitrified a me nā papa ahi.
