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

I nā makahiki i hala iho nei, ua ʻike ʻia ka nui o ka pauka resin rubber, ka pauka rubber wai-pale kiʻekiʻe a me nā pauka rubber haʻahaʻa loa ma ka mākeke e pani i ka emulsion VAE kuʻuna (vinyl acetate-ethylene copolymer), kahi i hoʻomaloʻo ʻia a hana ʻia me ka pauka rubber 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 pani i ka pauka latex redispersible?

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

01. Pauka latex hiki ke hoʻoheheʻe hou ʻia

I kēia manawa, ʻo nā pauka latex redispersible i hoʻohana nui ʻia ma ka honua: vinyl acetate a me ka pauka ethylene copolymer (VAC/E), ethylene, vinyl chloride a me ka pauka ternary copolymer vinyl laurate (E/VC/VL), acetic acid Vinyl ester, ethylene a me ka pauka ternary copolymer vinyl ester momona kiʻekiʻe (VAC/E/VeoVa), ʻo kēia mau pauka latex redispersible ʻekolu e noho aliʻi ana ma ka mākeke holoʻokoʻa, ʻoiai ka vinyl acetate a me ka pauka ethylene copolymer VAC/EE, e noho ana i kahi kūlana alakaʻi ma ke kahua honua a hōʻike i nā ʻano loea o ka pauka polymer redispersible. ʻO ia nō ka hopena loea maikaʻi loa ma ke ʻano o 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 e pono ai ka mortar (ʻo ia hoʻi, ka hiki ke kūkulu ʻia e pono ai);

4. ʻO ka resin polymer me nā monomers ʻē aʻe he mau ʻano o ka mea haʻalulu organik haʻahaʻa (VOC) a me ke kinoea hoʻonāukiuki haʻahaʻa;

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

6. Ke kū'ē kiʻekiʻe i ka saponification;

7. Loaʻa iā ia ka laulā ākea o ka mahana hoʻololi aniani (Tg);

8. He pilina piha maikaʻi loa kona, ka maʻalahi a me nā waiwai mechanical;

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

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

02. Pauka resin

ʻO ka hapa nui o ka pauka laholio "resin" ma ka mākeke aia ka mea kemika DBP. Hiki iā ʻoe ke nānā i ka pōʻino o kēia mea kemika, ka mea e hoʻopilikia ai i ka hana moekolohe kāne. He nui ka nui o kēia ʻano pauka laholio i hōʻiliʻili ʻia i loko o ka hale kūʻai a ma ka hale hana, a he ʻano volatility kona. ʻO ka mākeke ʻo Beijing, ka mea i kaulana no kona nui o ka "pauka laholio", i kēia manawa he ʻano inoa like ʻole o ka "pauka laholio" i hoʻomoʻa ʻia i loko o nā mea hoʻoheheʻe: ka pauka laholio wai ikaika kiʻekiʻe, ka pauka laholio resin, a pēlā aku. Nā ʻano maʻamau:

1. ʻAʻole maikaʻi ka hoʻopuehu ʻana, manaʻo kekahi he pulu, manaʻo kekahi he flocculent (pono ia he mea porous e like me ka sepiolite) a he keʻokeʻo kekahi a maloʻo iki akā ʻala maikaʻi ʻole nō naʻe;

2. He ʻala ʻawaʻawa loa ia;

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

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

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

6. Ua ʻōlelo ʻia ʻaʻole pono ka papa XPS i kahi ʻelele interface;

Ma o nā laʻana i loaʻa a hiki i kēia manawa, hiki ke hoʻoholo ʻia he resin ia e hoʻokumu ʻia ana i ka solvent i hoʻopili ʻia e nā mea porous māmā, akā makemake ka mea hoʻolako e pale aku i ka huaʻōlelo "solvent", no laila ua kapa ʻia ʻo ia ʻo "rubber powder".

hemahema:

1. He pilikia nui ka pale ʻana o ka mea hoʻoheheʻe i ka wā. I ka lā, e mae koke ia. Inā ʻaʻole i ka lā, e pala koke ka pilina pili ma muli o ke kūkulu ʻana o ka lua;

2. Ke kūpaʻa ʻana i ka wā ʻelemakule, ʻaʻole kūpaʻa nā mea hoʻoheheʻe i ka mahana, ʻike nā mea a pau i kēia;

3. ʻOiai ʻo ke ʻano hoʻopili ʻana e hoʻoheheʻe i ka pilina o ka papa insulation, ma ke ʻano ʻē, hoʻopau pū ia i ka pilina hoʻopili. Inā he pilikia me kēia pilikia ma ke kahua ma hope, e make ka hopena;

4. ʻAʻohe mea i hoʻohana mua ʻia ma nā ʻāina ʻē. Me ka ʻike kemika kumu i mākaukau ma nā ʻāina ʻē, ʻaʻole hiki ke ʻike ʻole i kēia mea.

Pauka latex hiki ke hoʻoheheʻe hou ʻia

1. ʻO ka huahana pauka latex redispersible he pauka redispersible wai-soluble, ʻo ia ka copolymer o ka ethylene a me ka vinyl acetate, me ka polyvinyl alcohol ma ke ʻano he colloid pale.

2. Loaʻa i ka pauka latex redispersible VAE nā waiwai hana kiʻiʻoniʻoni, 50% ka hopena wai e hana i kahi emulsion, a hana i kahi kiʻiʻoniʻoni e like me ka plastic ma hope o ke kau ʻia ʻana ma ke aniani no 24 mau hola.

3. Loaʻa i ke kiʻiʻoniʻoni i hana ʻia kekahi ʻano maʻalahi a me ke kūpaʻa wai. Hiki iā ia ke hōʻea i ke kūlana aupuni.

4. Loaʻa i ka pauka latex hiki ke hoʻoheheʻe hou ʻia ka hana kiʻekiʻe: loaʻa iā ia ka hiki ke hoʻopili kiʻekiʻe, ka hana kū hoʻokahi a me ka hana wai ʻole maikaʻi loa, ka ikaika hoʻopili maikaʻi, hāʻawi i ka mortar me ke kūpaʻa alkali maikaʻi loa, a hiki ke hoʻomaikaʻi i ka hoʻopili a me ka ikaika flexural o ka mortar. Ma waho aʻe o ka plasticity, ke kūpaʻa ʻana i ke kapa a me ke kūkulu ʻana, ʻoi aku ka ikaika o ka maʻalahi i ka mortar anti-cracking.

pauka resin

1. ʻO ka pauka laholio Resin kahi ʻano hoʻololi hou no nā huahana e like me ka laholio, resin, polymer molekala kiʻekiʻe, a me ka pauka laholio i wili maikaʻi ʻia;

2. He kūpaʻa maʻamau ka pauka ʻōpala resin, kūpaʻa i ka ʻaʻahu, hoʻopuehu maikaʻi ʻole, manaʻo kekahi he flocculent (pono ia he mea porous e like me ka sepiolite), a aia nā pauka keʻokeʻo (akā he ʻala ʻawaʻawa e like me ke kerosene);

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

4. ʻOi aku ka haʻahaʻa o ke kūpaʻa ʻana o ka pauka resin rubber i ke aniau a me ka wai ma mua o ka pauka latex. He pilikia nui ke kūpaʻa ʻana o ka aniau. I ka lā, e mae koke ia. Inā ʻaʻole i ka lā, e pala koke ka pilina pili. Ma muli o ke kūkulu ʻana o ka lua, e pala koke nō hoʻi;

5. ʻAʻohe hiki ke hoʻoheheʻe ʻia ka pauka laholio resin, ʻaʻole hoʻi e haʻi i ka maʻalahi. Wahi a nā kūlana hoʻāʻo no ka mortar insulation paia waho, ʻo ka helu hōʻino wale nō o ka papa polystyrene e kū nei i ke kūlana. ʻAʻole i kūlike nā ʻōkuhi ʻē aʻe i ke kūlana;

6. Hiki ke hoʻohana ʻia ka pauka laholio resin e hoʻopaʻa i nā papa polystyrene, ʻaʻole nā ​​​​mīkini vitrified a me nā papa pale ahi.
