Hoʻohana nui ʻia nā polyurethanes i nā polymers i hoʻokumu ʻia e ka hana ʻana i nā polyols me nā diisocyanates i mua o nā kemika e like me nā catalysts a me nā mea hoʻohui.Hoʻohana ʻia lākou no ka hana ʻana i nā huahana like ʻole ma kahi o nā ʻoihana āpau, e like me ka uila, kaʻa, nā kāmaʻa, ke kūkulu ʻana, ka pahu, a me nā mea ʻē aʻe, e hoʻoheheʻe ʻia i nā ʻano ʻokoʻa a hoʻomaikaʻi i nā mea kūʻai aku a me nā huahana ʻoihana.

Hoʻohana ʻia ka Polyurethane ma ke ʻano he ʻūhā paʻa no nā paia a me ka insulation o ka hale, ka ʻūhū maʻalahi i nā lako, a me nā mea hoʻopili, nā uhi, a me nā mea hoʻopaʻa no nā kaʻa kaʻa.ʻO kēia mau mea a pau e hāʻawi i ka waiwai o121 BPSi ka mākeke polyurethane i nā makahiki wānana o 2022-2032.

ʻO nā noi nui o ka polyurethane i loko o nā elastomers, nā pua, a me nā uhi e hāʻawi ana i ke kūpaʻa abrasion maikaʻi loa.Hoʻohana nui ʻia nā ʻōpū polyurethane rigid e like me nā mea insulation ma muli o ka hui pū ʻana o ke kumu kūʻai a me ka waiwai hoʻoili wela haʻahaʻa.ʻO ka hiki haʻahaʻa haʻahaʻa haʻahaʻa maikaʻi, ka nui o ka molecular structural variability, ke kumu kūʻai haʻahaʻa, a me ke kūpaʻa abrasion kiʻekiʻe ke kākoʻo nei i ka ulu mākeke.

Eia nō naʻe, ʻo ka hiki ʻole o ke aniau maikaʻi, ka liʻiliʻi o ka wela wela, ka lapalapa ʻana, a me nā mea ʻē aʻe, e hoʻopilikia paha i ka ulu koi polyurethane i nā makahiki e hiki mai ana.

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.
