ʻO nā mea hoʻoheheʻe paʻa paʻa ʻO nā huahana Lunamakaʻāinana, ʻoihana a me nā noi hou o ka polyurethane, phenolic resin, PET, PVC, SAN, PES a me nā mea ʻē aʻe.

ʻO ke kumu hoʻohāhā ka mea i hui pū ʻia, maʻamau he polymer thermoset (akā hiki ke ʻano thermoplastic) i hui pū ʻia me kahi kinoea kino inert (e like me ka nitrogen) a i ʻole kahi mea puhi kemika i ka wā o ke kaʻina hana.ʻO ka hopena,ʻaʻole ia he mea paʻa, akā, he microcellular foam haʻahaʻa haʻahaʻa i hui pūʻia me kahi pūpū kiʻekiʻe.

Hoʻemi ke kumu o ka foam i ke kaumaha holoʻokoʻa o ka mea, ʻoiai ʻo ka ʻili paʻa e ikaika a paʻa i ka hopena.Ua like ke ʻano o ka mea me ka sanwiti, me kahi kumu haʻahaʻa haʻahaʻa i hoʻopuni piha ʻia e ka ʻili kiʻekiʻe.Ma muli o kona ʻano kikoʻī ʻokoʻa, ʻoi aku ka maʻamau o nā cores foam structural 20% a 40% ma mua o nā polymers paʻa, aluminika, ke kila, ka mea hoʻoheheʻe pepa, a i ʻole nā ​​​​mea hana maʻamau.Ma muli o kona ʻano liʻiliʻi liʻiliʻi, ʻo nā mea kumu i hoʻohana ʻia no ka hana ʻana i nā ʻūhā hoʻolālā he mau polymers thermoplastic ma mua o nā thermosets.Hoʻohana pinepine ʻia nā thermoplastics, akā ʻaʻole i kaupalena ʻia i: polyurethane, polycarbonate, polyphenylene ether (Noryl), polybutylene terephthalate (Valox) a me ka acrylonitrile butadiene styrene a me nā mea kumu ʻē aʻe: polyurethane, phenolic Resin, PET, PVC, SAN, PES huāhu. huahana, ʻoihana a me nā noi hou.

Hana ʻia ʻo Polyurethane foam core mai ka CFC free foamed polyurethane, kahi pahu paʻa i hiki ke hana i nā facestocks, nā papa a me nā huahana maʻamau o nā ʻano like ʻole a me nā mānoanoa, ʻoiai ke kiʻekiʻe kiʻekiʻe, ka lapalapa ahi retardant rigid polyurethane foam sheets Ua loaʻa pū kekahi lāʻau, nā poloka a i ʻole nā ​​moldings.ʻO ke kumu kūʻai, kūpono a paʻa.ʻOiai ʻaʻole kūpono nā waiwai o ka polyurethane foam cores no nā noi koi, hoʻohana nui ʻia lākou e hoʻonui i ka mānoanoa, hana i ke ʻano cross-sectional, insulating quality, a me ka flotation.

ʻO nā koʻo polyurethane foam kahi koho kumu kūʻai haʻahaʻa no nā mea hana composite.Hoʻohana ʻia ka pahu polyurethane paʻa no ka flotation, insulation a i ʻole ma ke ʻano he kumu nui e like me ka hoʻonui ʻana i nā risers moana, hulls a me nā noi hoʻopono moana ʻē aʻe.
