Ua lilo nā polyurethane sealants i mea koho kaulana i waena o nā mea nona nā kaʻa e makemake ana e pale i kā lākou mau kaʻa mai nā mea kumu a mālama i kahi hoʻopau nani. Hele mai kēia sealant maʻamau me nā ʻano mea maikaʻi a me nā mea pono e noʻonoʻo ai ma mua o ka hoʻoholo ʻana inā kūpono ia no kāu kaʻa.
ʻO SV312 PU Sealant kahi huahana polyurethane ʻāpana hoʻokahi i haku ʻia e Siway Building Material Co., LTD.
Hoʻopili ia me ka makū i ka ea e hana i kahi ʻano elastomer me ka ikaika kiʻekiʻe, ka ʻelemakule, ka haʻalulu, nā haʻahaʻa a me nā waiwai kūpaʻa corrosive. Ua hoʻohana nui ʻia ʻo PU Sealant e hoʻohui i ke aniani mua, hope a me ka ʻaoʻao o nā kaʻa a hiki ke mālama i ke kaulike paʻa ma waena o ke aniani a me ka pena ma lalo. ʻO ka maʻamau, pono mākou e hoʻohana i nā pū e hoʻopaʻa ai i waho i ka wā i hana ʻia ai ma kahi laina a i ʻole ma ka bead.
ʻO kekahi o nā pono nui o ka polyurethane sealant ka lōʻihi. Hoʻokumu kēia ʻano sealant i kahi papa pale ikaika ma ka pena o kāu kaʻa, e kōkua ana i ka pale ʻana i kāu kaʻa mai nā ʻōpala, nā kukuna UV, a me nā mea haumia kaiapuni. Kōkua kēia i ka mālama ʻana i ke ʻano o ke kaʻa a pale i kona waiwai kūʻai hou i ka manawa. Hoʻohui ʻia, ʻike ʻia nā mea hoʻopaʻa polyurethane no kā lākou hana lōʻihi, e hāʻawi ana i kahi pale pale e hiki ke pale aku i ka paʻakikī o ka hoʻokele ʻana i kēlā me kēia lā a me ka ʻike ʻana i nā mea.
ʻO kekahi mea maikaʻi o ka polyurethane sealant ʻo ia kona kūpaʻa wai. Hoʻokumu kēia sealant i kahi wai hydrophobic e hoʻoulu ai i ka wai i luna a ʻōwili i ka pena o ke kaʻa. ʻAʻole wale kēia e kōkua i ka mālama ʻana i ka ʻālohilohi o kāu kaʻa, akā ʻoi aku ka maʻalahi o ka hoʻomaʻemaʻe a mālama ʻana. Eia hou, hiki i ka polyurethane sealants ke hāʻawi i kahi pae o ka pale ʻana i nā ʻili kemika a me nā kulu manu, e maʻalahi ka mālama ʻana i kāu kaʻa i ka maikaʻi.
Ma ka ʻaoʻao ʻē aʻe, aia kekahi mau hemahema e noʻonoʻo ai i ka wā e hoʻohana ai i ka polyurethane sealants. ʻO kekahi o nā hemahema nui, ʻo ia ka lōʻihi o ka hoʻōla ʻana: Ke hoʻohālikelike ʻia i kekahi mau mea hoʻopaʻa e like me ke silikoni, ʻo ka polyurethane sealants maʻamau e koi i kahi manawa lōʻihi e hoʻōla piha, hiki ke hoʻopaneʻe i ka hoʻopau ʻana o ka papahana.
ʻO kekahi hemahema o ka polyurethane sealant ʻo kona kumukūʻai. ʻOiai ke hāʻawi nei kēia ʻano sealant i ka lōʻihi a me ka pale, hiki ke ʻoi aku ke kumukūʻai ma mua o nā koho ʻē aʻe ma ka mākeke. Eia naʻe, manaʻo ka nui o nā mea kaʻa he waiwai kūpono e mālama i ka helehelena a me ka waiwai o kā lākou kaʻa no ka wā lōʻihi.
I ka hōʻuluʻulu ʻana, hāʻawi nā polyurethane sealants i nā ʻano mea maikaʻi a me nā hemahema i nā mea nona nā kaʻa e nānā nei e pale i ka pena o kā lākou kaʻa. ʻO kona lōʻihi, ke kūpaʻa wai, a me ka hana lōʻihi e lilo ia i koho kaulana no ka poʻe e ʻimi nei i kahi kiʻekiʻe o ka pale. Eia nō naʻe, ʻo ke kaʻina hana noiʻi ikaika a me nā kumukūʻai kiʻekiʻe paha he mea pōʻino no kekahi. ʻO ka mea hope loa, ʻo ka hoʻoholo e hoʻohana i ka polyurethane sealant no kāu kaʻa pono e kau ʻia ma kāu mau pono kikoʻī a me nā mea nui no ka mālama ʻana i ke ʻano a me ka waiwai o kāu kaʻa.
