Hana ʻia nā Polyether Polyols e ka hana ʻana i ka oxide organik a me ka glycol.

ʻO ka mea hoʻohana nui i hoʻohana ʻia ʻo Ethylene Oxide, Propylene Oxide, Butylene Oxide, Epichlorohydrin.

ʻO nā glycols nui i hoʻohana ʻia ʻo Ethylene Glycol, Propylene Glycol, Wai, Glycerine, Sorbitol, Sucrose, THME.

Loaʻa i nā polyol nā pūʻulu hydroxyl (OH) reactive e hana me nā pūʻulu isocyanate (NCO) ma nā isocyanates e hana i nā polyurethanes.

Nui nā ʻano polyether polyols no ka polyurethane.Hiki ke loaʻa nā mea PU me nā hana like ʻole me ka hopena ma waena o nā mea hoʻomaka a me ka polymerization olefin.

Ma ka hoʻololiʻana i ka PU raw mea a hoʻololi paha i ka catalyst, hiki ke hoʻololi i ka hana polyether.Aia kēia mau mea hoʻomaka i ka waiʻona diethyl, ka waiʻona ternary, tetrahydrofuran, a me nā polyols aromatic polyether, etc.

HOOLAHA

ʻO ka hoʻohana ʻana i ka polyether i hoʻohana ʻia ma PU ma mua o 80%.Hiki ke hoʻokaʻawale ʻia ka polyether polyurethane

Polyether Polyol (PPG),

Polymeric Polyol (POP),

ʻO Polytetramethylene ether glycol (PTMEG, i kapa ʻia ʻo polytetrahydrofuran polyol) e like me ka mea hoʻomaka.

Hoʻohana nui ʻia nā polyether polyols i loko o ka PU rigid foam, ka ʻūhā palupalu, a me ka hoʻoheheʻe ʻana i nā huahana.

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 kumu ʻoihana ʻē aʻe.
