ʻO ka pauka polymer hiki ke hoʻokuʻu ʻiarHoʻohana maʻamau ʻia ma ka paia o waho o ka hale me ka pauka putty a i ʻole nā hui ʻē aʻe, maʻamau me ka sima a me nā hui ʻē aʻe ma loko, a me ka pauka latex i hui pū ʻia me ka pauda putty e pena i waho, hāʻawi ia i nā kānaka i kahi ʻano he palupalu. manaʻo, a hiki ke hoʻonui piha i ka ikaika adsorption o ka mortar, i ʻoi aku ka lōʻihi o ke ola lawelawe o ka pā o waho.

Hōʻike mua ʻia kāna hana i ka hoʻomaikaʻi ʻana i ka adhesion o ka mortar, no ka mea, e komo ka pauka latex i loko o ka sima a piha i ka wai, no laila ʻoi aku ka maikaʻi o ka adhesion. Nui nā manawa i loaʻa iā mākou nā poʻo no ka mea ʻaʻole hiki i ka sima ke hoʻopaʻa me ka lāʻau a me ka fiber a me nā mea maka, akā me ka ka pauka polymer hiki ke hoʻoheheʻe ʻia, ʻaʻole pono mākou e hopohopo no nā mea a pau. Ua ʻike mākou a pau he ʻilihune loa ka pale ʻana o ka sima ma hope o ka paʻakikī, a ʻo ka hoʻohui ʻana o ka pauka latex e hoʻomaikaʻi i kona paʻakikī, i hiki ai iā ia ke kū i ke kaomi deformation kiʻekiʻe. ʻO ka microstructure o ka sima sima e hoʻololi ʻia e ia. E ālai ia i ka komo ʻana o ka wai o ka hale o loko a pale i ka wai mai ka komo ʻana i waho. A laila hoʻomaikaʻi ʻia ka mana anti-permeability o ka pā o waho. ʻAʻohe pono e hopohopo e pili ana i ke kahe wai i loko o ka hale ke ua. I luna.

ʻO ka pauka polymer hiki ke hoʻokuʻu ʻiaua hoʻohui ʻia i ka sima, i hui pū ʻia nā ʻāpana sima maikaʻi a me ka lepo, no laila e hoʻomaikaʻi maoli ʻia ka haʻahaʻa haʻahaʻa o ka mortar, a ʻoi aku ka ikaika o ka pale ʻana. No nā paia o waho , ʻAʻole e kahe maʻalahi i ka wai, maloʻo maloʻo, deformation ke kūlana o ka maikaʻi kūpono. Ma lalo o nā kūlana maʻamau, ʻoi aku ka pōkole o nā paia o waho maʻalahi, a maʻalahi ke haki ma hope o kekahi mau makahiki. No laila, hoʻohui pinepine ʻia ka pena latex i ke kaʻina hana i nā makahiki i hala iho nei e hoʻonui i kona ola lawelawe a hōʻoia i ke ola o nā kamaʻāina. Palekana pilikino a waiwai.

No laila, ma hea e hiki aika pauka polymer hiki ke hoʻoheheʻe ʻiahoʻohana ʻia?ʻO ka pauka polymer hiki ke hoʻokuʻu ʻiahiki ke hoʻohana ʻia ma kēia mau wahi: sima, gypsum-based, bonding mortar, plastering mortar, waterproof mortar, anti-cracking mortar, decorative mortar, ciment mortar, plastering mortar, masonry mortar, grout concrete repair and repair Mortar, batching ʻO ka pāpaʻa, ka lepo lepo (hoʻopaʻapaʻa ponoʻī ʻia no ka papa lalo, ka ʻili o ka ʻili, a me nā mea ʻē aʻe), ka lepo maloʻo, ka papa honua, ka hoʻopaʻa ʻana i ka tile, ka mea hoʻopili kūkulu, ka mea hoʻoheheʻe, ka mea hoʻohui, ka plaster hoʻopaʻa, stucco Gypsum, loko pā putty, ʻO ka putty pā o waho, ka lepo diatom, nā uhi wai, nā ʻāpana like ʻole,ka pauka polymer hiki ke hoʻoheheʻe ʻiahiki ke hoʻohana ʻia e like me nā plasticizers, tougheners, a

nā mānoanoa no nā mea hydraulic inorganic e like me ka sima a me ka gypsum , Binder, mea hana kiʻiʻoniʻoni, mea hana wai.

ʻO ka pauka polymer hiki ke hoʻokuʻu ʻiarloaʻa nā ʻano penei:

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. He 50% aqueous solution e hana i ka emulsion, kahi e hana ai 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 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, maikaʻi ka hoʻopaʻa ʻana i ka ikaika, hāʻawi i ka mortar maikaʻi loa i ke kūpaʻa alkali, a hiki ke hoʻomaikaʻi i ka adhesion a me ka ikaika flexural o ka mortar , Ma waho aʻe o ka plasticity. , ʻaʻahu i ke kūpaʻa a me ka hana, ʻoi aku ka ikaika o ka maʻalahi i ka mortar anti-cracking.
