ʻO ka hana ʻana o ka puʻu hoʻomanaʻo he mea kupanaha maoli ia o ka kemika a me ka ʻoihana hou.Hana ʻia ka pahu hoʻomanaʻo ma ka hana ʻana i nā mea like ʻole i loko o ke kaʻina like me ka polyurethane, akā me nā mea hana hou e hana ai i nā waiwai viscous, ʻoi aku ka paʻakikī i loaʻa i ka pahu hoʻomanaʻo.Eia ke kaʻina hana maʻamau i kāna hana ʻana:
1. ʻO nā polyols (nā waiʻona i loaʻa mai nā huahana petroleum a i ʻole nā ​​​​ʻaila mea kanu), isocyanates (organic amine-derived compounds) a me nā mea hoʻohālikelike i hui pū ʻia ma mua o ka hana ʻana.
2. Hoʻopili ʻia kēia hui ʻana i loko o kahi huʻu a ninini ʻia i loko o kahi ʻōpala.ʻO ka hopena exothermic, a i ʻole ka hoʻokuʻu wela, ʻo ia ka hopena, e hoʻohūhū ai ka hui ʻana a hoʻohua mai ka huʻa.
3. Hiki ke hoʻokomo ʻia ka hui ʻana i ka pua me ke kinoea a i ʻole nā ​​mea puhi puhi, a i ʻole i hoʻopaʻa ʻia i ka vacuum e hana i ka matrix open-cell.ʻO ka nui o ka hui polymer me ka ea e pili ana i ka nui o ka hopena.
4. Ma kēia pae, ua kapa ʻia ka ʻāpana nui o ka ʻūhā he "bun".Hoʻomaʻalili ʻia ka bun, a hoʻomehana hou ʻia a waiho ʻia e hoʻōla, hiki ke lawe i nā wahi āpau mai 8 mau hola a i kekahi mau lā.
5. Ma hope o ka ho'ōla ʻana i ka huʻa hoʻomanaʻo ʻaʻole inert (ʻaʻole reactive).Hiki ke holoi ʻia a hoʻomaloʻo ʻia e wehe i nā koena e waiho ana, a hiki ke nānā ʻia i kēia manawa no ka maikaʻi.
6. I ka pau ʻana o ka bun hoʻomanaʻo, ʻoki ʻia i ʻāpana no ka hoʻohana ʻana i nā moena a me nā huahana ʻē aʻe.Ua mākaukau nā ʻāpana moena e hui pū ʻia i loko o kahi moena i hoʻopau ʻia.
Hōʻike: ʻO kekahi o nā ʻike/kiʻi ma kēia ʻatikala mai ka Pūnaewele, a ua ʻike ʻia ke kumu.Hoʻohana wale ʻia lākou e hōʻike i nā ʻoiaʻiʻo a i ʻole nā ​​​​manaʻo i ʻōlelo ʻia ma kēia ʻatikala.No ke kamaʻilio a me ke aʻo ʻana wale nō lākou, ʻaʻole no nā ʻoihana ʻē aʻe.
