ʻO ke apo sila polyurethane ka mea i hōʻike ʻia e ke kūpaʻa ʻana i ka ʻaʻahu, ka ʻaila, ka waikawa a me ka alkali, ka ozone, ka ʻelemakule, ka mahana haʻahaʻa, ka haehae ʻana, ka hopena, a pēlā aku. Loaʻa i ke apo sila polyurethane kahi mana kākoʻo ukana nui a hoʻohana nui ʻia ma nā ʻano like ʻole. Eia kekahi, ʻo ke apo sila i hoʻolei ʻia he kūpaʻa i ka ʻaila, kūpaʻa i ka hydrolysis, kūpaʻa i ka ʻaʻahu, a he ikaika kiʻekiʻe, kūpono no nā lako aila kiʻekiʻe, nā lako hāpai, nā mea hana mīkini forging, nā lako hydraulic nui, a pēlā aku.
Apo sila polyurethane: he maikaʻi loa nā waiwai mechanical o ka polyurethane, a ʻoi aku ka maikaʻi o kona kūpaʻa i ke komo ʻana a me ke kūʻē ʻana i ke kaomi kiʻekiʻe ma mua o nā rubbers ʻē aʻe. He maikaʻi nō hoʻi ke kūpaʻa ʻana i ka ʻelemakule, ke kūʻē ʻana i ka ozone a me ke kūʻē ʻana i ka ʻaila, akā maʻalahi ka hydrolyze i ka mahana kiʻekiʻe. Hoʻohana nui ʻia ia no nā loulou sila kūpaʻa i ke kaomi kiʻekiʻe a me ke komo ʻana, e like me nā cylinders hydraulic. Ma ke ʻano laulā, ʻo ka pae mahana he - 45 ~ 90 ℃.
Ma waho aʻe o ka hoʻokō ʻana i nā koi maʻamau no nā mea apo sila, pono e hoʻolohe nā apo sila polyurethane i nā kūlana i lalo:
(1) Piha i ka elasticity a me ke kūpaʻa;
(2) ʻO ka ikaika mechanical kūpono, me ka ikaika hoʻonui, ka elongation a me ke kūpaʻa i ka haehae.
(3) Hana paʻa, paʻakikī ke pehu i ka waena, a me ka hopena emi iki o ka wela (hopena Joule).
(4) He maʻalahi ke hana a me ke ʻano, a hiki ke mālama i ka nui pololei.
(5) ʻAʻole ia e hōʻino i ka ʻili pili a hoʻohaumia i ka mea waena.
Ke nānā nei ʻo Ningbo Yokey Automotive Parts Co., Ltd i ka hoʻoponopono ʻana i nā pilikia mea laholio a nā mea kūʻai aku a me ka hoʻolālā ʻana i nā ʻano mea like ʻole e pili ana i nā hiʻohiʻona noi like ʻole.
