ʻO nā hiʻohiʻona, ka noi a me ka ʻokoʻa o ka pauka latex redispersible a me ka pauka resin

I kēia mau makahiki i hala iho nei, ua ʻike ʻia ka nui o ka pauka kaila resin, ka pauka wai-kūpaʻa kiʻekiʻe a me nā pauka ʻeleʻele ʻē aʻe ma ka mākeke e hoʻololi i ka emulsion VAE kuʻuna (vinyl acetate-ethylene copolymer), i hoʻomaloʻo ʻia a maloʻo. i hana ʻia me ka pauka lāʻau hiki ke hana hou ʻia.ʻO ka pauka latex i hoʻopuehu ʻia, no laila he aha ka ʻokoʻa ma waena o ka pauka resin a me ka pauka latex redispersible, hiki i ka pauka resin ke hoʻololi i ka pauka latex redispersible?

E noʻonoʻo pōkole i ka ʻokoʻa ma waena o nā mea ʻelua no ka ʻike ʻana:

01. ʻO ka pauka latex hiki ke hoʻopuka hou

I kēia manawa, ʻo nā pauka latex redispersible i hoʻohana nui ʻia ma 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 latex redispersible ʻekolu i hoʻomalu i ka mākeke holoʻokoʻa, ʻoi aku ka vinyl acetate a me ka ethylene copolymer pauda VAC/EE, noho i kahi kūlana kiʻekiʻe i 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 polymer resin me nā monomers ʻē aʻe he mau hiʻohiʻona o ka mea liʻiliʻi o ka mea hoʻoheheʻe organik (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.

02. Pauda resin

ʻO ka hapa nui o ka pauka "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 pauda lāʻau lapaʻau e hōʻiliʻili ʻia i loko o ka hale kūʻai a i loko o ke keʻena keʻena, a aia kekahi volatility.ʻO ka mākeke ʻo Beijing, ka mea i kaulana no ka nui o ka "rubber powder", i kēia manawa he ʻano inoa like ʻole o ka "rubber powder" i hoʻomoʻa ʻia i loko o nā solvents: kiʻekiʻe-ikaika wai-kūpaʻa lepo pauka, resin rubber pauka, etc.

1. ʻAʻole hiki ke hoʻopuehu ʻia, pulu kekahi, manaʻo kekahi he flocculent (he mea porous e like me sepiolite) a he 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 hana interface;

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

ʻO ka pauka latex hiki ke hoʻopuka hou ʻia

1. ʻO ka huahana latex pauka 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. Loaʻa i ka VAE redispersible latex pauka nā waiwai hana kiʻiʻoniʻoni, 50% wai wai e hana i ka emulsion, a hana i kahi kiʻiʻoniʻoni e like me ka 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 latex redispersible: he hiki ke 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 i ke kūpaʻa. a me ke kūkulu ʻana, ʻoi aku ka ikaika o ka maʻalahi i ka mortar anti-cracking.

resin pauda

1. He ʻano hoʻololi hou ʻo Resin rubber no nā huahana e like me ka rubber, resin, high molecular polymer, and finely ground rubber powder;

2. ʻO ka pauka Resin he mau lōʻihi ka lōʻihi, hoʻopaʻa kūʻē, hoʻopuehu maikaʻi ʻole, manaʻo kekahi i ka flocculent (pono he mea porous e like me sepiolite), a he mau pauka keʻokeʻo (akā, he ʻala ʻala e like me ke ʻaila);

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

4. He ha'aha'a ke kū'ē 'ana o ka ea a me ka wai o ka pauka resin ma mua o ka pauda latex.He pilikia nui ka pale ʻana i ka wā.I ka lā, e mahuka i loko o ka manawa pōkole.ʻOiai inā ʻaʻole ia i ka lā, ʻo ka pilina pili e Ma muli o ke kūkulu ʻia ʻana o ka lua, e decompose wikiwiki nō hoʻi ia;

5. ʻAʻole hiki ke hoʻoheheʻe ʻia ka pauka lāʻau Resin, e waiho wale i ka maʻalahi.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 no ka hoʻopaʻa ʻana i nā papa polystyrene, ʻaʻole nā ​​peʻa vitrified a me nā papa ahi.
