ʻO ka polyurethane rigid foam i kēia manawa i ʻike ʻia ma ke ao holoʻokoʻa ʻo ia ka mea ʻoi aku ka maikaʻi o ka hoʻokaʻawale hale.He haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, hoʻopaʻa haʻahaʻa maikaʻi, ikaika kulou kiʻekiʻe, ʻaʻohe hoʻoheheʻe wai, ʻaʻohe pala, ʻaʻohe nahu ʻiole i ʻai ʻia e nā pepeke, hoʻopaneʻe ahi maikaʻi a me ka nui o ka pale wela.
Hoʻohana ʻia ka lolouila e hoʻomalu i ka laina hana hana ʻokoʻa, no laila ua hoʻokumu ʻia ka polyurethane foaming kiʻekiʻe a me ka pā kila i uhi ʻia a paʻa.Hoʻohui ʻia ke kila kala paʻa a me nā mea kemika palupalu me ka polyurethane PU foam forming machine e hana i ka mea hou loa o ka ʻepekema a me ka ʻenehana hoʻomalu kaiapuni hale-polyurethane (PU) kala kila sandwich panel, ʻo ia ka moemoeā o nā mea kākau, nā mea hoʻolālā a me nā ʻenekinia.
1. ʻO ka polyurethane ʻoʻoleʻa loaʻa nā waiwai ʻeleʻele a me ka wai.ʻO ka helu kelepona paʻa o ka polyurethane paʻa ma luna o 90%, he mea hydrophobic a ʻaʻole e hoʻonui i ka conductivity thermal ma muli o ke komo ʻana o ka wai, a ʻaʻole e kahe ka wai o ka pā.
2. ʻO ka polyurethane maikaʻi he haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana wela maikaʻi.Ke 38 ~ 42kg/m3 ka mānoanoa o ka polyurethane paʻa, ʻo 0.018 ~ 0.024w/(mk) ka thermal conductivity wale nō, ʻo ia ka hapalua o ka EPS, a ʻo ia ka haʻahaʻa loa ma waena o nā mea wela wela i kēia manawa.
3. No ka mea, he maikaʻi loa ka hana ʻana o ka hoʻoheheʻe ʻana i ka wela o ka polyurethane sandwich plate, ma lalo o nā koi mālama mālama wela, hiki iā ia ke hoʻemi i ka mānoanoa o ka hale enveloppe hale, a laila e hoʻonui ai i ka wahi hoʻohana i loko.
4. Haʻahaʻa piha koina hana.ʻOiai ʻoi aku ka kiʻekiʻe o ke kumu kūʻai o ka pahu polyurethane paʻa ma mua o nā mea hoʻonaninani kuʻuna, e hoʻopau ʻia ke kumukūʻai hoʻonui e ka hoʻemi nui ʻana i nā kumukūʻai hoʻomehana a me ka hoʻomaha.
