huahana polyurethane foam

I loko o nā ʻoihana he nui, mai ke kūkulu ʻana a hiki i ka hana ʻana i nā lako, ʻo ka polyurethane foam ka mea i hōʻike ʻia i kahi hana mana o ka kemika hou. He mea maʻalahi kēia mea kupanaha a he mea hoʻokani kiʻekiʻe, e hoʻohuli i ko mākou honua a puni. ʻO kahi nānā hohonu i nā nuances o ka polyurethane foam no kāna kaʻina hana, hoʻomau ka hoʻoikaika ʻana i nā waiwai insulation a me ka laulā o nā hoʻohana ʻoihana a me nā mea ʻoluʻolu maikaʻi i hana ʻia. ʻO ka hohonu a mākou e hele ai, ʻoi aku ka maopopo o ka hohonu o kahi polyurethane foam maoli.

ʻO ka ʻepekema Hoʻohihi ma hope o nā huahana polyurethane foam

Aia ma ka puʻuwai o kēlā me kēia huahana polyurethane foam ʻoʻoleʻa kahi hopena kemika i hoʻonohonoho pono ʻia i kapa ʻia he polymerization. He hui ia o ʻelua mau mea nui: diisocyanates a me polyols. He mau polymers thermosetting i hoʻopaʻa kemika i nā isocyanates, a loaʻa i loko o lākou nā molekole me nā ʻāpana hana hou i hoʻopau ʻia e nā hui hydroxyl. Hoʻohui ʻia kēia mau mea i kahi mahana a me ke kaomi e hana ai i ka huʻa i hiki ke hoʻoheheʻe ʻia i nā ʻano like ʻole, nā ikaika, nā maʻalahi. Eia kekahi, ʻo nā catalysts, nā mea puhi puhi a me nā mea hoʻohui ke kuleana no ka hoʻoponopono hou ʻana i kēia mau waiwai me ka ʻole o nā ʻūhā hāmama (hoʻohana maikaʻi ʻia e like me nā mea hoʻoheheʻe leo) a i ʻole nā ​​​​huhū kelepona paʻa me kona waiwai insulating maikaʻi loa ʻaʻole hiki ke hiki.

No ke aha e koho ai i ka huahana RONGHE polyurethane foam?

Nā waeʻano huahana pili

ʻAʻole ʻike i kāu mea e ʻimi nei?
E kelepona i kā mākou mau mea kūkākūkā no nā huahana hou aʻe i loaʻa.
