Panel Sandwich Polyurethane

Ma ke ʻano he mea hoʻomehana hale e hoʻohana pono ana i ka ikehu, ua lilo ka panela sanwika polyurethane i mea nui o nā hale hana ʻoihana hou, nā hale kūʻai logistics, a me nā hale mālama anu. ʻO kēia ʻano panela hale, ka mea e hoʻohui i nā papa ʻili metala me ka mea polyurethane, e manaʻo ʻia e lilo i mea nui i ka wā e hiki mai ana.

Hana maikaʻi loa
ʻO ka pōmaikaʻi nui o ka panela sanwika polyurethane aia i kā lākou hana insulation thermal kupaianaha. Loaʻa i nā mea huʻa polyurethane nā waiwai insulation thermal maikaʻi, me ka conductivity thermal haʻahaʻa e like me 0.017-0.025 W/(m·K). ʻO ke ʻano kēia, hiki i kahi panela he 5 kenimika wale nō ka mānoanoa ke hoʻokō i ka hopena insulation like me ka pā sima hoʻokahi mika ka mānoanoa. Mahalo i kāna hana insulation maikaʻi loa, ua lilo nā panela sanwika polyurethane i mea makemake ʻia no ke kūkulu ʻana i nā hale mālama anu.

ʻO ka pale wai, ke kūpaʻa i ka makū, a me ke kūpaʻa kiʻekiʻe he mau pono hou aʻe o nā panela sanwika polyurethane. ʻOi aku ka nui o ka cell pani o ka polyurethane foam core ma mua o 95%, e pale pono ana i ke komo ʻana o ka makū. ʻOi aku ka liʻiliʻi o ka omo wai o nā panela sanwika polyurethane ma mua o 3%. I ka manawa like, ma lalo o nā loli mahana o 30°C, ʻoi aku ka liʻiliʻi o ka loli dimensional o nā panela ma mua o 1%, e hōʻoiaʻiʻo ana i ka hoʻohana lōʻihi me ka ʻole o ka deformation.

Hiki i ke kūpaʻa ahi o nā panela sanwika polyurethane ke hōʻea i ka Papa B1. He lapalapa nā panela sanwika polyurethane, akā e pau ana ko lākou ʻā ʻana i loko o 3 kekona ma hope o ka wehe ʻia ʻana mai ke lapalapa ahi. ʻOiai ua emi iki ko lākou ʻano ma mua o nā panela sanwika huluhulu pōhaku ma kēia ʻano, ua hoʻokō nō lākou i nā koi palekana ahi kumu.

Ma ke ʻano kūkulu, mahalo i nā papa ʻelua o nā panela metala ma luna a me lalo, he ikaika kūkulu maikaʻi ko nā panela sanwika polyurethane. ʻOi aku ka ikaika compressive o nā panela sanwika polyurethane ma mua o 150 kPa. Eia nō naʻe, ʻo ka mea nui he polyurethane foam, ka mea e māmā ai nā panela he 30-60% ma mua o nā huahana kuʻuna. ʻO kēia ka mea e makemake nui ai nā panela sanwika polyurethane no ke kūkulu ʻana i nā mea māmā.

Koi Hana Kiʻekiʻe
I kēia manawa, ua hana pono ʻia ke kaʻina hana o nā panela sanwika polyurethane. Hoʻohana nā mea hana alakaʻi, e like me Harbin Dong'an Building Sheets Co., Ltd., i nā laina hana hoʻomau e hoʻohui i ke kaʻina holoʻokoʻa o ka hoʻohua ʻana, ka hoʻōla ʻana, a me ke ʻano ʻana i nā panela.

ʻO ka hoʻohuʻu ʻana a me ke kūkulu ʻana i ke kaomi kiʻekiʻe he hana nui ia i ka hana ʻana o nā panela sanwika polyurethane. ʻO ke ʻano o ka hoʻohuʻu ʻana e hoʻoholo pololei i ka hana o nā panela. I ka wā o ka hana ʻana, pono nā mea hana e kāohi pono i ka mahana o ka papa kaulahao a me nā mea hoʻohuʻu. He mea koʻikoʻi nō hoʻi ka wikiwiki o ka laina hana, no ka mea, e pili ana ia i ke ʻano like o ke kaʻina hana hoʻohuʻu koʻikoʻi.
