He mau ʻano mea hoʻopiha piha e pili ana i ka Sofa noho hōkele
Hiki ke hoʻokaʻawale ʻia nā mea hoʻopiha piha o ka sofa hotel, nā lako ʻahaʻaina hōkele i nā mea aʻe:
1. Hoʻokaʻawale ʻia ka ʻūhā polyuretin palupalu (i ʻike ʻia he sponge) no nā sponges i hoʻopiha ʻia me ka sofa i ʻekolu mau ʻāpana. ʻO ka sponge maʻamau he ʻōhuʻu i hana ʻia e ka polyether maʻamau a me ka TDI.
Hōʻike ʻia ia e ka elasticity maikaʻi, palupalu, a me ka hanu. ʻO ka sponge kiʻekiʻe-rebound he sponge i hana ʻia e nā polyphisms ikaika a me TDI ke kino nui. Loaʻa i kona mau hiʻohiʻona nā waiwai mechanical maikaʻi a me ka elasticity maikaʻi. ʻO ka ukana hoʻopiʻi nui, ke kūpaʻa ahi, ka hanu maikaʻi. He ʻano sponge ka chaos sponge e like me ka limu maoli me nā ʻano nui like ʻole. Hōʻike ʻia ia e ka elasticity maikaʻi, a he cushioning maikaʻi loa i ka wā e hoʻopiʻi ai a rebound.
2. ʻO ka hoʻopiha piha ʻana: i lalo e hoʻopiha i ka hoʻopiha ʻana i ka sofa, ʻoluʻolu ka noho ʻana, liʻiliʻi deformation no ka manawa lōʻihi, ʻo ka hemahema ʻo ka lohi o ka rebound a ʻoi aku ka kiʻekiʻe o ke kumukūʻai. E hoʻohana maʻamau me ka sponge i nā sofa kiʻekiʻe, a kūpono paha no ka cushion.
3. Hoʻopiha artificial: Hoʻopiha ʻia ka pulupulu artificial i ka hoʻopiha ʻana i ka sofa, he palupalu a ʻoluʻolu hoʻi e noho ai, akā ʻilihune nā waiwai mechanical a he liʻiliʻi ka ukana paʻa.
