Hiki i ka pipi ʻana i ka polyurethane ma nā pahu ke hoʻokaʻawale maoli ʻia?

ʻO ke ʻano maʻamau o ka hale pahu ka hoʻolako ʻana i ka malu no nā limahana ma ke kahua kūkulu.Hiki iā lākou ke noho i ke kauwela wela a i ʻole ke anuanu?ʻAʻole anei e anu a wela paha?ʻO kaʻoiaʻiʻo, inā he kauwela a hoʻoilo paha, hiki ke hoʻopili ʻia nā ipu.Inā ʻaʻole ʻoe e manaʻoʻiʻo mai iaʻu, e heluhelu wale!

ʻAʻole i loaʻa i ka ipu pono ka hana o ka insulation thermal.He anu i ka hooilo a me ke kau wela.I ke kauwela, ʻo ka mahana o waho he 38 °, a ʻo ka mahana i loko o ka ipu ke kiʻekiʻe pinepine i 42 °.No laila, he mea koʻikoʻi ka papa insulation thermal.Ma hope o ka hoʻopaʻa ʻia ʻana o ka hale pahu, pono e hoʻohui i kahi papa insulation thermal a hoʻokomo i nā mea ea ea.

Hoʻopiʻi ʻia ka papa insulation thermal ma ʻaneʻi me ka polyurethane hard foam.ʻOiaʻiʻo, aia kekahi mau hana hoʻokalakupua wela, e like me ka huluhulu wela, ka papa huluhulu pōhaku, ka papa silicate, a me nā mea ʻē aʻe.

No laila he aha ka polyurethane spraying?

ʻO ka pulupulu polyurethanee pili ana i ka hoʻohana ʻana i ka mīkini hoʻoheheʻe polyurethane kūikawā e pīpī i nā mea maka polyurethane ma lalo o ka hana o nā mea hoʻohui like ʻole e like me nā mea hoʻohāhā, catalysts, a me nā mea pale ahi, ma o ka hopena kiʻekiʻe a me ka hoʻololi ʻino i loko o kahi keʻena hui me kahi wahi liʻiliʻi, a laila hala. ma o ka nozzle o ka pu puhi.He polimer molekala kiʻekiʻe e hana ana i nā kulu noe maikaʻi a hoʻopuehu like ma ka ʻili o kekahi mea.

He aha nā pōmaikaʻi o ka pīpī ʻana i ka polyurethane ma nā ipu?

1. Thermal insulation, kiʻekiʻe pono a me ka ikehu hoola.

He haʻahaʻa ka conductivity thermal o ka polyurethane thermal insulation material, a maikaʻi ka mālama ʻana i ka wela a me nā hopena insulation wela, ʻaʻole i hoʻohālikelike ʻia e nā mea hoʻonaninani wela ʻē aʻe.Ma nā hale noho maʻamau, hoʻohana ʻia ka polyurethane rigid foam e like me ka hale wai a me ka wela-insulating hale, ʻo kona mānoanoa he hapakolu wale nō o nā mea kuʻuna, a ʻo kona kūpaʻa wela ʻaneʻane ʻekolu mau manawa i ko lākou.No ka mea, he 0.022 ~ 0.033W/(m*K) ka thermal conductivity o ka polyurethane, ua like ia me ka hapalua o ka papa extruded, a ʻo ia ka mea haʻahaʻa haʻahaʻa wela wela ma waena o nā mea wela wela i kēia manawa.

2. He māmā ka ukana o ka hale.

He haʻahaʻa haʻahaʻa a me ke kaumaha o ka polyurethane insulation, no laila ua maʻalahi ka ukana ma luna o ka hale a me ka paia.ʻO ke kaupaku o ka polyurethane thermal insulation material he hapahā o ke ʻano o ka hale kuʻuna, he mea nui loa ia e hoʻomaikaʻi i ke ʻano holoʻokoʻa o ka hale a hoʻemi i ke kumukūʻai kūkulu, no laila ʻoi aku ka maikaʻi no nā hale hale ākea ākea a lahilahi. .

3. He maʻalahi ke kūkulu ʻana a wikiwiki ka holomua.

ʻO ka ʻenehana ma ʻaneʻi ʻo ka polyurethane spraying a me ka hoʻoulu ʻana ma ka pūnaewele, hiki ke hana i nā hana hale paʻakikī, ʻoi aku ka maikaʻi o ka ʻumi ma mua o ka waiho ʻana i nā mea kahiko.Hoʻemi pū ia i ka ikaika o ka hana, hoʻomaikaʻi i ke kaiapuni hana, a hoʻemi i ka pollution kaiapuni.

ʻO ka nui o ka hoʻonui ʻana o ka polyurethane insulation ma ka pūnaewele he 15-18 mau manawa, no laila he liʻiliʻi ka nui o ka lawe ʻana i nā mea maka.Wahi a nā helu helu, hiki iā ia ke hōʻemi i ke kumukūʻai kaʻa kaʻa ma mua o 80% i hoʻohālikelike ʻia me ka hoʻohana ʻana i nā mea kuʻuna, a hoʻemi nui hoʻi ia i ka hana o nā neʻe kaʻa kaʻa ma ke kahua kūkulu.

4. ʻO ka maikaʻi ʻenehana maikaʻi, ke ola lōʻihi a me ke kumu kūʻai haʻahaʻa

ʻO ka polyurethane insulation material kahi pahu microporous paʻa me ka helu kelepona paʻa ma mua o 92%.He paheʻe kona ʻili ponoʻī a he mea maikaʻi ʻole impermeable.Hoʻohana ʻia ka ʻenehana hoʻoheheʻe pololei ʻana i ke kūkulu ʻana e hana i ka hoʻokumu holoʻokoʻa me ka ʻole o ka humuhumu ʻana.

Hiki ke hoʻopaʻa paʻa ʻia ka polyurethane thermal insulation material i ka papa kumu, a hiki i kona ikaika hoʻopaʻa ʻana ke ʻoi aku ma mua o ka ikaika o ka waimaka o ka pahu ponoʻī, no laila ua hoʻohui ʻia ka polyurethane thermal insulation material a me ka papa kumu, a ʻaʻole maʻalahi ka delamination. a pale ʻia ke komo ʻana o ka wai ma ka interlayer.He mea maʻalahi ke komo ʻana i ka wai a me ka maʻemaʻe o nā mea hoʻonaninani wela maʻamau, a he pōkole loa ke ola lawelawe o nā membrane wai maʻamau, a pono e hoʻoponopono mau a hoʻololi ʻia;ʻOiai ke ola o ka lawelawe ʻana o nā mea insulation thermal polyurethane hiki ke piʻi ma mua o 10 mau makahiki, a ʻo ke kumukūʻai mālama i mālama ʻia i kēia manawa he nui loa.
