ʻO ka polyurethane foam maʻalahi (FPF) he polymer i hana ʻia mai ka hopena o nā polyols a me isocyanates, kahi kaʻina hana kemika i hoʻokumu ʻia i ka makahiki 1937. Hōʻike ʻia ka FPF e kahi ʻano cellular e hiki ai i kekahi degere o ka hoʻopiʻi a me ka resilience e hāʻawi i kahi hopena cushioning.Ma muli o kēia waiwai, he mea makemake ia i loko o nā lako, nā moena, nā noho kaʻa, nā mea haʻuki, ka ʻeke, nā kāmaʻa, a me ka cushion carpet.He kuleana koʻikoʻi nō hoʻi ia i ke kani ʻana a me ka kānana.

Hoʻohana pinepine ʻia ka foam i loko o nā pā nui i kapa ʻia ʻo slabstock, i ʻae ʻia e hoʻōla i loko o kahi mea paʻa paʻa a laila ʻoki a hana ʻia i mau ʻāpana liʻiliʻi i nā ʻano nui a me nā hoʻonohonoho.Hoʻohālikelike pinepine ʻia ke kaʻina hana slabstock me ka piʻi ʻana o ka palaoa—ninini ʻia nā kinikini wai ma luna o ke kāʻei conveyor, a hoʻomaka koke lākou i ka huʻa a piʻi aʻe i loko o kahi pūpū nui (ma kahi o ʻehā kapuaʻi ke kiʻekiʻe) ke hele lākou i lalo o ka mea lawe.

Hoʻopili pinepine ʻia nā kumu kumu no ka FPF me nā mea hoʻohui e loaʻa ai nā waiwai i makemake ʻia.ʻO kēia mau mea mai ka hōʻoluʻolu a me ke kākoʻo e pono ai no ka noho upholstered a hiki i ka haʻalulu-absorption i hoʻohana ʻia no ka pale ʻana i nā waiwai i hoʻopaʻa ʻia, a hiki i ke kūpaʻa abrasion lōʻihi e koi ʻia e ka cushion carpet.

Hiki i nā amine catalysts a me nā surfactants ke hoʻololi i ka nui o nā cell i hana ʻia i ka wā o ka pane ʻana o nā polyols a me isocyanates, a no laila e hoʻololi i nā waiwai o ka huʻa.Hiki i nā mea hoʻohui ke hoʻokomo i nā mea pale ahi no ka hoʻohana ʻana i nā mokulele a me nā kaʻa a me nā anti-microbials e pale ai i ka ʻōpala i nā noi waho a me ke kai.

Hōʻike: Ua haʻi ʻia ka ʻatikala maiwww.pfa.org/what-is-polyurethane-foam.No ka kamaʻilio a me ke aʻo ʻana, mai hana i nā kumu pāʻoihana ʻē aʻe, ʻaʻole ia e hōʻike i nā manaʻo a me nā manaʻo o ka hui, inā pono ʻoe e paʻi hou, e ʻoluʻolu e kelepona i ka mea kākau kumu, inā he hewa, e ʻoluʻolu e kelepona koke iā mākou e hana i ka hana holoi.
