Hōʻike ʻia ke apo sealing polyurethane e ka pale ʻana i ka lole, ka aila, ka waikawa a me ka alkali, ozone, ʻelemakule, haʻahaʻa haʻahaʻa, haehae, hopena, a me nā mea ʻē aʻe. Eia kekahi, ʻo ke apo sealing hoʻoheheʻe he ʻaila kūpaʻa, hydrolysis resistant, wear-resistant, a he ikaika kiʻekiʻe, kūpono ia no nā mea ʻaila kiʻekiʻe kiʻekiʻe, nā mea hoʻokiʻekiʻe, nā mea hana mīkini forging, nā lako hydraulic nui, etc.

Polyurethane seal apo: ʻoi aku ka maikaʻi o ka polyurethane, a ʻoi aku ka maikaʻi o kona pale ʻana a me ke kūpaʻa kiʻekiʻe ma mua o nā rubbers ʻē aʻe. ʻOi aku ka maikaʻi o ka pale ʻana i ka wā kahiko, ka pale ozone a me ka ʻaila, akā maʻalahi ka hydrolyze i ka wela kiʻekiʻe. Hoʻohana maʻamau ia no nā loulou hoʻopaʻa paʻa kiʻekiʻe a paʻa ʻole, e like me nā cylinders hydraulic. ʻO ka maʻamau, ʻo ka pae wela - 45 ~ 90 ℃.

Ma waho aʻe o ka hoʻokō ʻana i nā koi maʻamau no ka hoʻopaʻa ʻana i nā mea apo, e hoʻolohe pū nā apo sealing polyurethane i kēia mau kūlana:

(1) Piha i ka elasticity a me ke kūpaʻa;

(2) ʻO ka ikaika mechanical kūpono, e like me ka ikaika hoʻonui, elongation a me ka pale ʻana i ka waimaka.

(3) Hoʻokō paʻa, paʻakikī e pehu i ka waena, a me ka hopena liʻiliʻi thermal shrinkage (Joule hopena).

(4) He maʻalahi ka 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 ke ʻano.

Ke nānā aku nei ʻo Ningbo Yokey Automotive Parts Co., Ltd i ka hoʻoponopono ʻana i nā pilikia o nā mea kūʻai aku a me ka hoʻolālā ʻana i nā ʻano mea like ʻole e pili ana i nā hiʻohiʻona noiʻi like ʻole.
