I nā makahiki i hala iho nei, he nui ka resin rubber pauka, kiʻekiʻe-ikaika wai-kūpaʻaka pauka polymer hiki ke hoʻoheheʻe ʻiaa ua ʻike ʻia ka pauda lāʻau makamae loa ma ka mākeke e pani i ka emulsion VAE kuʻuna (vinyl acetate-ethylene copolymer), i hoʻomaloʻo ʻia a hiki ke hana hou ʻia.ʻO ka pauka latex dispersible, a laila he aha ka ʻokoʻa ma waena o ka pauka lāʻau resin a me ka pauka latex redispersible, hiki ke hoʻololi i ka pauka latex redispersible?
1. RDP polymer pauka hou
I kēia manawa, ʻo nā pauka polymer dispersible i hoʻohana nui ʻia i ka honua: vinyl acetate a me ethylene copolymer rubber powder (VAC/E), ethylene a me vinyl chloride a me vinyl laurate terpolymer rubber pauka (E/VC/VL), acetic acid Vinyl ester a ʻO ka ethylene a me ka momona momona vinyl ester terpolymer rubber pauka (VAC/E/VeoVa), kēia mau pauka polymer dispersible ʻekolu i hoʻomalu i ka mākeke holoʻokoʻa, ʻoi aku ka vinyl acetate a me ka ethylene copolymer rubber pauka VAC/E/VeoVa E, he kūlana alakaʻi i ka honua. kahua a hōʻike i nā ʻano ʻenehana o nā pauka polymer dispersible.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. Loaʻa i ka ʻike noi noi ma ke kahua kūkulu;
3. Hiki iā ia ke hoʻokō i nā waiwai rheological i koi ʻia e ka mortar (ʻo ia hoʻi ka pono hana e pono ai);
4. ʻO ka resin polymer me nā monomers ʻē aʻe nā hiʻohiʻona o nā mea hoʻoheheʻe organik haʻahaʻa (VOC) a me nā kinoea hoʻonāukiuki haʻahaʻa;
5. Loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa UV maikaʻi, ke kūpaʻa wela maikaʻi a me ke kūpaʻa lōʻihi;
6. He kiʻekiʻe saponification kū'ē;
7. Loaʻa i ka laula wela hoʻololi aniani ākea loa (Tg);
8. Loaʻa iā ia ka hoʻopaʻa piha piha ʻana, ka maʻalahi a me nā waiwai mechanical;
9. Loaʻa i ka ʻike lōʻihi loa i ka hana kemika e pili ana i ka hana ʻana i nā huahana paʻa maikaʻi a me ka ʻike i ka mālama ʻana i ke kūpaʻa mālama;
10. He mea maʻalahi ke hui pū me ka colloid pale (polyvinyl alcohol) me ka hana kiʻekiʻe.
2. Ka pauka resin
ʻO ka hapa nui o nā pauka lāʻau "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.He heluna nui o ia mau pauda kopa e ahu ana i loko o nā hale kūʻai a me nā hale hoʻokolohua, a ua hiki ke hoʻololi i kekahi ʻano.ʻO ka mākeke ʻo Beijing, kahi kaulana no kāna hana ʻana i ka "rubber powder", i kēia manawa ua puka mai ke ʻano o ka "rubber powder" i hoʻomoʻa ʻia i nā solvents me nā inoa like ʻole: ikaika kiʻekiʻe wai-kūpaʻa i ka pauka adhesive, resin adhesive pauka, etc. :
1. ʻAʻole hiki ke hoʻopuehu, pulu kekahi, manaʻo kekahi poʻe flocculent (he mea porous e like me sepiolite), a he keʻokeʻo kekahi a maloʻo iki akā ʻala nō naʻe;
2. Aala loa;
3. Ua hoʻohui ʻia kekahi mau kala, a ʻo nā waihoʻoluʻu o kēia manawa he keʻokeʻo, melemele, hina, ʻeleʻele, ʻulaʻula, etc.
4. He liʻiliʻi loa ka huina hoʻohui, a ʻo ka huina hoʻohui no hoʻokahi tona he 5 ~ 12 kg;
5. He mea kupanaha ka ikaika mua.ʻAʻohe ikaika o ka sima no nā lā ʻekolu, a hiki iā ia ke ʻino i ka papa insulation a pipili.
6. Ua ʻōlelo ʻia e hiki ke hoʻohana ʻia ka papa XPS me ka ʻole o ka mea kikowaena.
Ma o nā laʻana i loaʻa i kēia manawa, hiki ke hoʻoholo ʻia he resin i hoʻopaʻa ʻia i ka solvent i hoʻopili ʻia e nā mea porous māmā, akā makemake ka mea kūʻai aku 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 volatilize i 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. Aging resistance, solvent ʻaʻole 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 ma ka pae hope, e make ka hopena;
4. ʻAʻohe kumu no ka noi ʻana ma waho.Me ka ʻike makua o ka ʻoihana kemika kumu ma waho, ʻaʻole hiki ke ʻike ʻole i kēia mea.
hōʻuluʻulu manaʻo:
Loaʻa i ka pauka latex dispersible:
1. ʻO ka redispersible latex powder product he wai-soluble redispersible pauka, he copolymer o ka ethylene a me ka vinyl acetate, a hoʻohana i ka waiʻona polyvinyl e like me ka colloid pale.
2. Loaʻa i ka VAE redispersible latex pauka nā waiwai hana kiʻiʻoniʻoni, ʻo 50% ka hopena wai e hana i kahi emulsion, a hana ia i kahi kiʻiʻoniʻoni e like me ka plastik ma hope o ke kau ʻana ma ke aniani no nā hola 24.
3. ʻO ke kiʻiʻoniʻoni i hoʻokumu ʻia he mau mea maʻalahi a me ka pale wai.Hiki ke hōʻea i nā kūlana aupuni.
4. He kiʻekiʻe ka hana o ka pauka latex redispersible: he hiki ke hoʻopaʻa kiʻekiʻe, hana kūʻokoʻa a me ka hana wai ʻole, ka ikaika hoʻopaʻa maikaʻi, hāʻawi i ka mortar me ke kūpaʻa alkali maikaʻi loa, a hiki ke hoʻomaikaʻi i ka adhesiveness a me ka ikaika flexural o ka mortar., plasticity, aahu i ke kū'ē a me ke kūkulu ʻana, ʻoi aku ka ikaika o ka maʻalahi i ka mortar anti-cracking.
ʻO ka pauka resini:
1. He ʻano hou o ka hoʻololi ʻana i ka pauka Resin no ka lāʻau, resin, macromolecular polymer, ground rubber powder a me nā mea ʻē aʻe.
2. ʻO ka pauka Resin he mea maʻamau ka lōʻihi, ke kūpaʻa abrasion, ka dispersibility maikaʻi ʻole, ke manaʻo nei kekahi i ka flocculent (pono ia he mea porous e like me sepiolite), a me ka pauka keʻokeʻo (akā, he ʻala ʻala e like me ke kerosene).
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 volatilize i ka manawa pōkole.ʻOiai inā ʻaʻole ia i ka lā, ʻo ka pilina pili, No ka mea he hana lua ia, e hoʻoheheʻe wikiwiki ʻia.
5. ʻAʻole hiki ke hoʻoheheʻe ʻia ka pauka Resin.E like me ka nānā ʻana o ka mortar insulation waho no nā paia o waho, ʻo ka nui o ka luku ʻana o ka papa polystyrene e hoʻokō i ka maʻamau.ʻAʻole kūpono nā hōʻailona ʻē aʻe.
6. Hiki ke hoʻohana wale ʻia ka pauka resin glue no ka hoʻopaʻa ʻana i nā papa polystyrene, ʻaʻole no ka hoʻopaʻa ʻana i nā pahu vitrified a me nā papa ahi.
