ʻO wai ka maikaʻi?
Ke ʻimi nei nā ʻohana a me nā mea hale i kahi hoʻonā e pale ai i ko lākou home mai ka wai, e hāʻule lākou i loko o ʻelua mau ʻāpana o nā uhi i lilo i mea kaulana loa; polyurethane a me ka epoxy. Hiki ke maʻalahi ka Polyurethane Yuru, ʻo ia ka mea hiki ke hoʻokipa i nā neʻe liʻiliʻi a hiki i ka epoxy ke ikaika a paʻa i ka wai.
He kumu no ka Polyurethane a me ka Epoxy
No ka ʻike ʻana i ka ʻokoʻa o kēia mau uhi ʻelua, e nānā pono kākou i kēlā me kēia. ʻO ka polyurethane pale wai hiki ke maʻalahi ma ke ʻano o nā uhi. He kūpono kēia maʻalahi no ka pale ʻana i nā ʻili e haki. Inā hoʻololi iki ka lepo ma lalo, no ka laʻana, ʻoi aku ka liʻiliʻi o kahi uhi polyurethane ma mua o ka substrate ma lalo. ʻO ka ʻokoʻa, ʻoi aku ka ikaika a ʻoi aku ka paʻakikī o nā uhi epoxy. ʻO ia ke ʻano inā e neʻe a flexes paha ka ʻili, ʻoi aku ka maʻalahi o nā uhi epoxy i ka haki.
ʻO ka ʻokoʻa nui ʻē aʻe ma waena o kēia mau uhi ʻelua e hele pū me ka wai. He maikaʻi nā uhi polyurethane i ka pale ʻana i ka wai - ʻo ia hoʻi, hiki iā lākou ke pale i ka wai mai ke komo ʻana i loko. Eia nō naʻe, ʻoi aku ka maikaʻi o nā ʻāpana epoxy i ka wai.
ʻO nā pono a me nā pōʻino o ka Polyurethane a me ka Epoxy
ʻO ka uhi wai polyurethane makemake nui ʻia e ka poʻe he nui no ka mea ua lawa lākou e hoʻokipa i nā neʻe liʻiliʻi. ʻO kēia ka mea kūpono iā lākou no nā wahi wai wai e like me nā papahele o lalo, hiki ke hoʻololi iki. Ma waho aʻe o ka maʻalahi o nā uhi PU, hāʻawi pū kekahi i ka pale maikaʻi mai ka lā (UV kukui). He mea nui kēia no ka mea hiki i ke kukui UV ke hoʻohaʻahaʻa i nā ʻili he nui i ka wā lōʻihi. Eia nō naʻe, hele mai nā uhi polyurethane me kekahi mau hemahema. Hoʻopilikia ia i nā hiʻohiʻona i ka wā lōʻihi no ka mea hiki ke ʻohi maʻalahi.
Nā Manaʻo maikaʻi:
He maʻalahi a maʻalahi kona mau neʻe liʻiliʻi e mālama
Nā pale mai ka pōʻino kukui ultraviolet
Maikaʻi i ka mālama ʻana i ka wai
Nā wahi maikaʻi ʻole:
Hiki ke ʻohi maʻalahi
ʻAʻole lōʻihi e like me nā uhi epoxy
Epoxy Waterproofing
ʻO kekahi mea kaulana loa Polymer waterproofing ʻO nā haʻina i loaʻa he mau uhi epoxy. A aloha ka poʻe iā lākou no ka mea he ikaika, lōʻihi, a ʻoi aku ka maikaʻi o ka pale ʻana i nā ʻōpala ma mua o nā uhi polyurethane. Hoʻokahi mea e hoʻomaopopo ai, ʻoi aku ka maʻalahi o nā uhi epoxy i ka polyurethane. ʻO kēlā ʻano hiki ʻole ke hiki iā lākou ke uhaʻi inā hoʻololi nui ka lepo ma lalo o lākou.
Polyurethane vs. Epoxy
I ka wā e pili ana i ka mālama ʻana i ka wai, ka makū a me ka haʻahaʻa ma waho o kou home a i ʻole kāu ʻoihana, ʻo ka polyurethane a me ka epoxy coatings he koho maikaʻi loa akā aia ko lākou ʻokoʻa i ka palekana, ka hana a me ka noi. ʻOi aku ka maʻalahi o ka hoʻopau ʻana o ka polyurethane, no laila ʻaʻole hiki ke haki, akā hiki ke ʻoki ʻia a ʻaʻohe lōʻihi o ke ola. ʻO nā uhi epoxy, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka paʻakikī a ʻoi aku ka lōʻihi, akā ʻaʻole hiki ke maʻalahi a paʻa paha inā hoʻololi ke kumu ma lalo o lākou.
