Hōʻike Noiʻi ʻOihana Polyurethane (Mahele A)

1. Nānā o ka ʻoihana Polyurethane

ʻO ka Polyurethane (PU) kahi mea polymer koʻikoʻi, nona ka laulā o nā noi a me nā ʻano huahana like ʻole e lilo ia i ʻāpana koʻikoʻi o ka ʻoihana hou.Hāʻawi ke ʻano kūʻokoʻa o ka polyurethane iā ia i nā waiwai kino a me nā kemika, e hoʻohana nui ʻia i nā wahi e like me ke kūkulu ʻana, nā kaʻa, nā lako a me nā kāmaʻa.Hoʻokumu ʻia ka hoʻomohala ʻana o ka ʻoihana polyurethane e nā ʻano like ʻole e like me ke koi mākeke, ka ʻenehana ʻenehana, a me nā hoʻoponopono kūlohelohe, e hōʻike ana i ka hiki ke hoʻololi a me ka hiki ke hoʻomohala.

2. Nānā o nā huahana Polyurethane

(1) Puka Polyurethane (Pua PU)
ʻO ka pahu polyurethaneʻO ia kekahi o nā huahana nui o ka ʻoihana polyurethane, hiki ke hoʻokaʻawale ʻia i loko o ka pahu paʻa a me ka pahu maʻalahi e like me nā pono noi like ʻole.Hoʻohana maʻamau ʻia ka ʻūhā paʻa i nā wahi e like me ke kūkulu ʻana i ka hale a me nā pahu kaʻa kaʻa kaulahao, ʻoiai hoʻohana nui ʻia ka foam maʻalahi i nā huahana e like me nā moena, nā sofas, a me nā noho kaʻa.Hōʻike ka polyurethane foam i nā waiwai maikaʻi loa e like me ka māmā, ka insulation thermal, ka hoʻoheheʻe ʻana i ke kani, a me ke kūpaʻa paʻa, e pāʻani ana i kahi kuleana nui i ke ola hou.

• ʻO Pua Pua ʻoʻoleʻa:ʻO ka pahu polyurethane koʻikoʻi he mea ʻōhū me kahi hale paʻa-cell, i hōʻike ʻia e ka paʻa paʻa maikaʻi a me ka ikaika mechanical.Hoʻohana maʻamau ia i nā noi e koi ana i ka ikaika kiʻekiʻe a me ka paʻakikī, e like me ke kūkulu ʻana i ka hale, nā pahu kaʻa kaʻa kaulahao, a me nā hale kūʻai refrigerated.Me kona kiʻekiʻe kiʻekiʻe, ʻo ka puʻupuʻu PU paʻa e hāʻawi i ka hana insulation maikaʻi a me ke kūpaʻa paʻakikī, e lilo ia i mea kūpono no ke kūkulu ʻana i ka insulation a me ke kaulahao kaulahao.
• ʻO ka puʻupuʻu PU maʻalahi:ʻO ka puʻupuʻu polyurethane maʻalahi he mea ʻōhuhi me kahi ʻano o ka wehe ʻana, ʻike ʻia no kona palupalu a me ka elasticity.Hoʻohana maʻamau ia i ka hana ʻana i nā moena, nā sofas, a me nā noho kaʻa, e hāʻawi ana i ka hōʻoluʻolu a me ke kākoʻo.Hiki ke hoʻolālā ʻia ka puʻupuʻu PU maʻalahi i nā huahana me nā ʻano like ʻole a me ka paʻakikī e hoʻokō i ka hōʻoluʻolu a me nā koi kākoʻo o nā huahana like ʻole.ʻO kona palupalu maikaʻi a me ke kūpaʻa e lilo ia i mea hoʻopiha piha kūpono no nā lako a me nā ʻenehana automotive.
• ʻO ka ʻili ponoʻī PU Foam:ʻO ka pahu polyurethane ʻili ponoʻī he mea ʻūhā e hana i kahi papa hoʻopaʻa paʻa ponoʻī ma luna o ka ʻili i ka wā o ka huʻa.Loaʻa iā ia kahi ʻili maʻemaʻe a me ka paʻakikī o ka ʻili kiʻekiʻe, hoʻohana mau ʻia i nā huahana e koi ai i ka maʻalahi o ka ʻili a me ke kūpaʻa.Hoʻohana nui ʻia ka puʻupuʻu PU ʻili ponoʻī i nā lako, nā noho kaʻa, nā lako hoʻoikaika kino, a me nā māla ʻē aʻe, e hāʻawi ana i nā huahana me kahi hiʻohiʻona nani a paʻa.

(2) Polyurethane Elastomer (PU Elastomer)
ʻO ka polyurethane elastomer he elasticity maikaʻi loa a me ke kū'ēʻana i ka lole, i hoʻohana mauʻia i ka hanaʻana i nā kaʻa, nā sila, nā mea vibration damping, a me nā mea'ē aʻe. a me nā mea kūʻai aku.

(3)Pāʻani Polyurethane (PU Adhesive)

Hoʻopili polyurethaneloaʻa nā waiwai hoʻopaʻa maikaʻi a me ke kū'ē o ke kaiapuni, hoʻohana nui ʻia i ka hana lāʻau, ka hana automotive, textile adhesive, etc. Hiki i ka polyurethane adhesive ke ho'ōla koke ma lalo o nā ʻano mahana like ʻole a me nā kūlana haʻahaʻa, hana i nā mea paʻa ikaika a paʻa, hoʻomaikaʻi i ka maikaʻi o ka huahana a me ka hana.

3. Hoʻohui a me nā noi o ka Polyurethane

Nā ProductsPolyurethane, ma ke ʻano he mea polymer versatile, he mau noi ākea i nā ʻano ʻano like ʻole, i hoʻokaʻawale ʻia i loko o nā ʻāpana aʻe:
(1) Huahana Hua
ʻO nā huahana Foam ka nui o ka ʻōhū paʻa, ka huʻa maʻalahi, a me ka ʻili ʻili ponoʻī, me nā noi me:

• Hoʻohui hale: Hoʻohana maʻamau ʻia ka ʻūhā paʻa i ke kūkulu ʻana i nā mea insulation e like me nā papa insulation o waho a me nā papa insulation hale, e hoʻomaikaʻi maikaʻi ana i ka ikehu o nā hale.
• Mea Hana Mea Hana: Hoʻohana pinepine ʻia ka ʻūhā maʻalahi i ka hana ʻana i nā moena, nā sofas, nā noho, e hāʻawi ana i nā noho ʻoluʻolu a me nā ʻike hiamoe.Hoʻohana ʻia ka ʻūhā ʻili ponoʻī no ka hoʻonani ʻana i ka ʻaoʻao o ka hale, hoʻonui i ka nani o ka huahana.
• ʻO ka hana kaʻa: Hoʻohana nui ʻia ka foam maʻalahi i nā noho kaʻa, nā puka i loko, e hāʻawi ana i nā ʻike noho ʻoluʻolu.Hoʻohana ʻia ka ʻūhā ʻili ponoʻī no nā panela kūloko automotive, nā huila hoʻokele, hoʻonui i ka nani a me ka hōʻoluʻolu.

(2) Nā Huahana Elastomer
Hoʻohana nui ʻia nā huahana Elastomer ma nā wahi aʻe:

• ʻO ka hana kaʻa: Hoʻohana nui ʻia ka polyurethane elastomers i ka hana kaʻa, e like me nā kaila, nā ʻōnaehana hoʻokuʻu, nā sila, e hāʻawi ana i ka haʻalulu maikaʻi a me ka hoʻopaʻa ʻana i nā hopena, hoʻomaikaʻi i ke kūpaʻa kaʻa a me ka hōʻoluʻolu.
• Nā Sila Hana Hana: Hoʻohanaʻia ka polyurethane elastomers ma keʻano he mau mea no nā silaʻoihana likeʻole, e like me O-rings, sealing gaskets, me ka maikaʻi o kaʻaʻahu a me ka paleʻana i ka corrosion, e hōʻoiaʻiʻo ana i ka hana sealing lako.

(3) Nā Huahana Hoʻopili
Hoʻohana nui ʻia nā huahana adhesive ma nā wahi aʻe:

• Woodworking: Hoʻohana pinepine ʻia nā polyurethane adhesives no ka hoʻopaʻa ʻana a me ka hoʻohui ʻana i nā mea lāʻau, me ka ikaika hoʻopaʻa maikaʻi a me ke kūpaʻa wai, hoʻohana nui ʻia i ka hana ʻana i nā lako, ka hana lāʻau, etc.
• Hana Hana: Hoʻohana ʻia nā polyurethane adhesives no ka hoʻopaʻa ʻana i nā ʻāpana like ʻole i ka hana kaʻa, e like me nā paneli kino, nā sila puka makani, e hōʻoiaʻiʻo ana i ka paʻa a me ka hoʻopaʻa ʻana i nā ʻāpana automotive.
