ʻO ka plastic foam kekahi o nā ʻano nui o nā mea synthetic polyurethane, me ke ʻano o ka porosity, no laila he liʻiliʻi ka nui o ka pilina, a kiʻekiʻe kona ikaika kikoʻī. Wahi a nā ʻano mea like ʻole a me nā haʻina, hiki ke hana ʻia i palakiko, semi-rigid a paʻakikī hoʻi i ka polyurethane foam plastic etc.
Hoʻohana ākea ʻo PU foam, ʻaneʻane komo i loko o nā ʻāpana āpau o ka hoʻokele waiwai aupuni, keu hoʻi i nā lako hale, nā moe, nā halihali, nā hau, ke kūkulu ʻana, ka hoʻāno a me nā noi ʻē aʻe.
Hoʻohana nui ʻia ka hua polyurethane i nā pono hana, nā mea moe a me nā huahana o ka hale, e like me nā ipukukui a me nā noho, nā ʻūlū backrest, nā moena a me nā uluna.
I ka hana maoli a me ka hoʻohana ʻana, pono pinepine kēia mau huahana i nā koi kiʻekiʻe o ka pale ʻana i ka melemele a me ka pale ahi. Hāʻawi ka ʻoihana i nā ʻano hoʻohui i hiki ke kōkua maikaʻi i ka hoʻomaikaʻi ʻana i ka hana huahana.
Hiki i ka ʻoihana ke hāʻawi i lalo o nā hua hoʻohui ʻoho PU:
| KUPANAHA | HUAOLELO | CAS | ʻAno KANAKA | NĀ PALAPALA |
| ULAULA UV | YIHOO UV1 | Hoʻohana ākea ʻia i PU, lina, hua a me nā pono hana ʻē aʻe. | ||
| YIHOO UV571 | TINUVIN 571 | Hoʻohana ākea i ka pale thermoplastic PUR a me nā plastics huʻihuʻi integral, polychloride plasticized paʻakikī, PVB, PMMA, PVDC, EVOH, EVA, hoʻōla wela kiʻekiʻe i ka polyester unsaturated a me PA, PET, PUR a me PP fiber spinning AIDS. | ||
| YIHOO UV B75 | TINUVIN B75 | Hoʻohuihui ʻia ka hui UV, hoʻohana nui ʻia ma ka PU, ka lina a i ʻole ka uhi PUR, e like me ka lole lole, ka lole kumu a me ka ʻili synthetic. | ||
| ANTIOXIDANT | YIHOO AN333 | JP333E | Phenol-free antioxidant, i hoʻohana ʻia ma ke ʻano he stabilizer kōkua kōkua ma PVC, hoʻomaikaʻi i ke kala a me ka transparency o nā huahana PVC. Hiki nō ke hoʻohana i loko o ka laholio a me ka PU mea e hoʻomaikaʻi i ke kūnewa kūpaʻa o nā huahana. | |
| YIHOO AN340 | Phenol manuahi antioxidant, hiki ke hoʻohana ākea ma PVC, ABS, SBR, CR etc. | |||
| PALAPALA HUAKU | YIHOO FR950 | / | ʻO ka chiffin phosphate ester retardant flame, kūpono kūpono no ka pale ahi pale PU. Hiki iā ia ke kōkua i ka mahele ma Kaleponi 117 hae, standard FMVSS302 o ka huahuakai kaʻa, ka haole Pelekane 5852 Crib 5 a me nā pae hoʻohālikelike pale ahi ʻē aʻe. ʻO FR950 ka pale ahi kūpono e hoʻololi iā TDCPP (carcinogenicity) a me V-6 (i loaʻa ka carcinogen TCEP). |
No ka hoʻolako ʻana i nā mea hoʻopili polymer i nā noi kikoʻī hou aʻe, ua hoʻokumu ka ʻoihana i kahi moʻo huahana e uhi ana ma lalo o nā noi: PA polymerization & moditive additives, PU hua hua hoʻohui, PVC polymerization & hoʻololi hoʻololi, PC mea hoʻohui, TPU elastomer mea hoʻohui, haʻahaʻa VOC kaʻa ʻoki nā mea hoʻohui lole hoʻopau. nā mea hoʻohui āpau, nā mea hoʻohui uhi, nā mea hoʻonaninani mea hoʻopili, API a me nā huahana kemika e like me zeolite a pēlā aku.
Hoʻokipa ʻia ʻoe e kāhea iā mākou no nā nīnau!
