Pa o loko
Hoʻokumu ʻia o ka huahana
ʻO ka polyurethane paʻa paʻa paʻa i hoʻopaʻa ʻia he wai-hōʻoia, mālama i ka wela a me ka wela-insulating foam i hana ʻia e ka hui ʻana i nā ʻāpana A a me B i kekahi ʻāpana a me ke ʻano o nā hopena kemika.
▲He mea ʻāpana
ʻO ka mea ʻāpana A he mea hoʻohui i haku ʻia me ka polyol (hui ʻia ka polyether a i ʻole polyester) a me ka wai, catalyst, stabilizer, flame retardant a me nā mea hoʻohui ʻē aʻe, i ʻike mau ʻia he mea keʻokeʻo.
▲B mea ʻāpana
ʻO ka mea nui o ka mea B-component he isocyanate, ʻo ia ka wai ʻeleʻele, i ʻike maʻamau ʻia he mea ʻeleʻele.
ʻO ka wai piha B1 ka pāpaʻi ʻana i ka polyurethane ʻoʻoleʻa (PU) ʻōnaehana hoʻopaʻa anu
Hoʻokumu ʻia ka pīpī ʻana i ka polyurethane ʻeleʻele ma luna o ka isocyanate (mea ʻeleʻele ʻeleʻele) a me nā polyols (ʻike mau ʻia he mea keʻokeʻo i hui pū ʻia me nā catalysts, modifiers, anti-aging agents. phosphorus nitrogen flame retardants (noiʻi kūʻokoʻa a me dewelopment), ka wai (ka noiʻi kūʻokoʻa a me ka hoʻomohala ʻana) a me nā mea hoʻohui ʻē aʻe. (ʻike pinepine ʻia he mau mea keʻokeʻo). ʻO ka hui pū ʻana. ʻO ka pulupulu kiʻekiʻe kiʻekiʻe, a me ka hoʻokumu ʻana i ka ʻūhā ma ka pūnaewele i kahi ʻano hou o ka polymerthermal insulation kiʻekiʻe-molecular a me nā mea wai wai. ʻO ka huʻa ʻawaʻawa maʻamau.
ʻO ka polyurethane sandwich panel (PUR) ʻōnaehana hoʻopaʻa anu
E kāpīpī i ka polyurethane roofing system no ka mālama ʻana i ka ikehu, mālama i ka wela a me ka wai ʻole
Hoʻohana ka Polyurethane Sand Panels (PUR) i nā paneli foampolyurethane (a i ʻole polyurethane i hoʻololi ʻia) ma ke ʻano he thermalinsulation material., ʻOi aku ka maikaʻi o ka helu ahi., A ʻoi aku ka laulā o ka noi.
ʻO ka uhi ʻana o ka hale paʻa i nā hale hou a me nā hale e noho nei kekahi o nā wahi noi nui o ka pahu rigidpolyurethane sprayed.
Ua hōʻoia ka hoʻomaʻamaʻa ʻana i ka hoʻoheheʻe ʻana i ka pahu polyurethane paʻa i ka wela o ka hale e hiki ke mālama i ka 80% o ka manawa a me 50% o ke kumukūʻai hoʻolimalima i hoʻohālikelike ʻia me nā ʻano hana insulation wela maʻamau. ʻO ka pā pāpaʻi, hiki ke hoʻokō maʻalahi i ka hoʻoulu ʻana. ʻO ka pīpī ʻana i ka polyurethane foam ʻoʻoleʻa hiki ke ho'ōla wikiwiki a hiki ke hele i luna ma hope o iwakālua mau minuke.Hiki iā ʻoe ke koho i ka hoʻopili pololei ʻana i kahi papa pale kiʻi ʻoniʻoni hiki ke pale aku i nā kukuna ultraviolet ma ka ʻili o ka ʻūhā.
Hiki ke maʻalahi a hoʻolele koke ʻia ka pulupulu ʻana i ka polyurethane foam ʻoʻoleʻa ma luna o ka hale maloʻo a me ka lepo ʻole.
E kāpī i ka polyurethane pā waho e mālama i ka ikehu, mālama i ka wela a me ka ʻōnaehana hoʻohui wai
ʻO nā mea maikaʻi o ka pīpī ʻana i ka polyurethane foam paʻa no ka pale ʻana i ka paia o waho:
1.Good ka wela malama hana a me ka haʻahaʻa thermal conductivity
2.High dimensional paʻa, ʻaʻohe kulou, ʻaʻohe warping, ʻaʻohe deformation
3.Long ola lawelawe (ʻo ke ola lawelawe like me ka hale hiki ke hoʻohana ʻia) 4. ʻO ka hana kūpono, ka hoʻohana ākea a me ka wā kūkulu pōkole
5.Strong hoʻopaʻa ikaika, hoʻopili hoʻohui, ʻaʻohe lua, ʻaʻohe haki a hāʻule ʻole
6. Hana maikaʻi ʻole wai, ka hale paʻa paʻa holoʻokoʻa
7.Non-fluorine, non-toxic a me ka haumia ʻole
8.Superior flame retardant hana, maoli B1 papa mea
ʻO ka pā pale maloʻo e hoʻopakele i ka ikehu-hoʻōla ʻōnaehana hoʻoheheʻe waho
Hiki ke hoʻohana ʻia ka ʻōnaehana insulation thermal waho ma hope o ka pā pale a i ʻole ka maloʻo maloʻo o waho o ka pā pale pale no ka hana hou ʻana i nā hale hou a me nā hale e kū nei.Hiki i ka ʻili metala a i ʻole pōhaku o ka ʻōnaehana pale pale maloʻo ke pale i nā ʻāpana o waho o ka pā mai ka wā, a hiki ke hoʻohana ʻia ma ke ʻano he hale hoʻonaninani e hāʻawi i nā mea hoʻolālā i nā koho hou aʻe.
E hoʻopaʻa mua i nā ʻāpana i hoʻopili ʻia o ka ʻōnaehana pā pale i ka paia, a laila e kāpī i ka polyurethanea ʻoʻa ʻaʻa a puni ka paia a me nā ʻāpana i hoʻopili ʻia.E like me ke ʻano o ka pā pale maloʻo maloʻo, hiki ke hoʻokomo ʻia ka keel vertical a i ʻole aluminurguide rail e hoʻoponopono a hoʻokomo i ka pā pale.E mālama i kahi ʻāpana hoʻoheheʻe 2-4cm ma waena o ka pā pale a me ka papa hoʻoheheʻe ʻana i mea e maloʻo ai ka wahi a ʻaʻohe wai.ʻO ka polyurethane foam kahi thermalinsulation kūʻokoʻa a me ka hana wai, a hiki ke pale i ka leakage o waho.
ʻO ka wai piha B1 ka pāpaʻi ʻana i ka polyurethane ʻoʻoleʻa (PU) ʻōnaehana hoʻopaʻa anu
ʻO ke kaumaha o ka polyurethane polyurethane i hoʻoheheʻe ʻia a ʻaʻohe hopena i ka hale kūkulu kumu. ʻO nā koi no ka ʻili i hoʻoheheʻe ʻia, ua mālie ke kaʻina hana, wikiwiki ka wikiwiki, ʻaʻole pili ka hoʻohana ʻana i ka hale.ʻO ia ke koho maikaʻi loa e hoʻohana i ka hana hoʻohui ʻana i ka wai a me ka thermal insulation o ka polyurethane polyurethane i hoʻoheheʻe ʻia e hana i ka hoʻololi ʻana i ka wai a me ka hoʻololi ʻana i ka wela ma ka hale o nā hale kūkulu kila.
