ʻO ka pahu polyurethane koʻikoʻi, i kapa ʻia ʻo rigid polyurethane foam, ʻo ia ka lua o ka pahu polyurethane maʻalahi i ka nui o nā huahana polyurethane.
ʻO ka polyurethane rigid foams ka hapa nui o ka hale paʻa-cell, nona ka hopena insulation thermal maikaʻi, ke kaumaha māmā, ka ikaika kikoʻī kiʻekiʻe, ke kūkulu kūpono a me nā ʻano maikaʻi ʻē aʻe.
I ka manawa like, loaʻa iā lākou nā hiʻohiʻona o ka insulation kani, ka haʻalulu kūʻē, ka uila uila, ka wela wela, ke anu anuanu, ka pale ʻana i ka solvent, a me nā mea ʻē aʻe, a hoʻohana nui ʻia i nā mea Insulating no nā friji a me nā freezers, mālama anu, nā kaʻa i hoʻoheheʻe ʻia, nā hale. , hoʻohana ʻia nā pahu mālama, a me nā pipeline i nā manawa i hoʻokaʻawale ʻole ʻia, e like me ka lāʻau hoʻohālike, nā mea hoʻopili, etc.
Ma ka ʻōlelo maʻamau, hoʻohana nui ʻia ka pahu polyurethane paʻa me ka haʻahaʻa haʻahaʻa ma ke ʻano he mea hoʻokalakupua wela (hoʻōla wela), a hiki ke hoʻohana ʻia ka pahu polyurethane paʻa me ke kiʻekiʻe kiʻekiʻe ma ke ʻano he kumu hana (lāʻau hoʻohālikelike).
Hoʻomoʻa pinepine ʻia ka ʻūhā polyurethane ʻoʻoleʻa i ka lumi wela, a maʻalahi ke kaʻina hana.E like me ke kiʻekiʻe o ka hana mechanization, hiki ke hoʻokaʻawale ʻia i ka manual foaming a me ka mechanical foaming;e like me ke kaomi i ka wā e hoʻoulu ai, hiki ke hoʻokaʻawale ʻia i loko o ka pahu kiʻekiʻe a me ka haʻahaʻa haʻahaʻa;e like me ke ʻano o ka hoʻoheheʻe ʻana, hiki ke hoʻokaʻawale ʻia i ka ninini ʻana i ka puaʻa a me ka pīpī ʻana i ka puaʻa.
ʻO nā hoʻohana nui o ka polyurethane rigid foam penei:
1. ʻO ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana i nā meaʻai a me nā ʻoihana ʻē aʻe: e like me nā pahu hau, nā pahu hau, ka mālama anu, nā kaʻa paʻa, etc.
2. Hoʻopiliʻia nā mea hanaʻoihana: e like me nā pahu mālama, nā paipu, a me nā mea'ē aʻe.
3. Nā mea kūkulu hale: Ma nā ʻāina i kūkulu ʻia ma ʻEulopa a me ʻAmelika, ʻoi aku ka nui o ka polyurethane foam no ke kūkulu ʻana ma kahi o ka hapalua o ka nui o ka hoʻohana ʻana i ka huʻa paʻa, ʻoi aku ia ma mua o hoʻokahi manawa ka nui o ka huʻa paʻa no nā friji a me nā pahu manuahi;ma Kina, hoʻohana ʻia ka ʻōpala paʻa i ka ʻoihana kūkulu.ʻAʻole laha loa ka noi e like me nā ʻāina i kūkulu ʻia ma ke Komohana, no laila nui loa ka hiki ke hoʻomohala.
4. ʻOihana kaʻa: e like me nā hale kaʻa, nā ʻāpana o loko, etc.
5. Imitation lāʻau: kiʻekiʻe-density (density 300 ^ 700kg / m3) polyurethane rigid foam a i ʻole aniani fiber reinforced rigid foam mea he structural foam plastic, ʻike ʻia hoʻi he lāʻau hoʻohālike, nona ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi, ka ʻōpala a paʻakikī. kaʻina hana hoʻoheheʻe maʻalahi, Loaʻa iā ia nā hiʻohiʻona o ka hana kiʻekiʻe o ka hana, ʻoi aku ka ikaika ma mua o ka lāʻau maoli, a me ka haʻahaʻa haʻahaʻa ma mua o ka lāʻau maoli.Hiki iā ia ke pani i ka lāʻau no nā huahana kiʻekiʻe.
6. ʻO nā mea hana ipu, etc.
ʻO nā huahana polyurethane hard foam āu e makemake ai e hana, e ʻoluʻolu e nīnau mai iā mākou, hiki iā mākou ke hāʻawi i kahi hopena papahana maikaʻi loa.
