ʻO ka polyurethane rubber, he elastomer versatile e hoʻopili ana i ke āpau ma waena o ka lāʻau a me ka plastic, ua lilo ia i pōhaku kihi i nā ʻoihana like ʻole ma muli o kāna mau waiwai. ʻIke ʻia no kona ikaika kiʻekiʻe, elasticity, a me ke kūpaʻa ʻana i ka ʻaʻahu a me ka waimaka, hoʻohana nui ʻia ka polyurethane rubber i nā ʻāpana e like me ka automotive, kūkulu, a me ka hana ʻana. ʻO kona hiki ke hoʻololi i nā noi like ʻole i koho ʻia no nā mea ʻenekinia a me nā mea hoʻolālā. No ka laʻana, ʻo kona kūpaʻa abrasion kiʻekiʻe, hiki ke piʻi i ka 10 mau manawa ʻoi aku ka nui ma mua o nā mea ʻē aʻe, ua lilo ia i mea nui i nā wahi koʻikoʻi kiʻekiʻe. No ka ʻimi ʻana i nā noi ākea a me nā pono o ka polyurethane rubber, hiki iā ʻoe ke kuhikuhi i nā ʻike kikoʻī i hāʻawi ʻia ma lalo o ke kumuhana. ʻO ka Rubber Polyurethane.
Nā waiwai o ka Polyurethane Rubber
Paʻa a me ka paʻakikī
ʻO kekahi o nā hiʻohiʻona koʻikoʻi o ka polyurethane rubber ʻo kona kūpaʻa maikaʻi loa. Hāʻawi ia i kahi ākea ākea o nā pae paʻakikī, mai ka haʻahaʻa e like me 20 Shore A a ma luna o 80 Shore A, kūpono ia no nā noi like ʻole. Loaʻa kēia maʻalahi i ka paʻakikī ma o nā ʻano hana like ʻole, e ʻae ana i nā mea hana e hoʻopili i nā mea i nā pono kikoʻī. No ka laʻana, ʻoi aku ka maikaʻi o nā mea hoʻoheheʻe palupalu no nā noi cushioning, aʻo nā ʻano ʻoi aku ka paʻakikī e hoʻohana ʻia i nā wili ʻoihana a me nā sila.
Kūʻē abrasion
ʻOi aku ka polyurethane rubber i ka pale ʻana i ka abrasion, ʻoi aku ka maikaʻi o nā mea kahiko. ʻO 5 a 10 mau manawa ke kiʻekiʻe o kona pale ʻana ma mua o ka lāʻau kūlohelohe a i ʻole nā mea hana ʻē aʻe. ʻO kēia waiwai he koho maikaʻi loa ia no nā noi e like me nā kāʻei conveyor, gaskets, a me nā huila, kahi e hiki ʻole ai ke hoʻopaʻapaʻa mau a me ka lole.
Kiekie Tensile ikaika
ʻO ka ikaika tensile o ka polyurethane rubber hiki ke piʻi i 600 kgf/cm², ʻoi aku ka kiʻekiʻe ma mua o nā elastomers ʻē aʻe. ʻO kēia ikaika kiʻekiʻe e hōʻoiaʻiʻo i ka mea hiki ke kū i nā ukana kaumaha a me nā koʻikoʻi me ka ʻole o ka deforming a i ʻole ka haki ʻana, i mea kūpono no ke koi ʻana i nā noi ʻoihana.
Elasticity a me ke koena deformation haʻahaʻa
Hōʻike ka polyurethane rubber i ka elasticity maikaʻi loa, me kahi elongation pili a hiki i 600%. ʻOiai ma lalo o ia elongation kiʻekiʻe, he liʻiliʻi ke koena deformation, maʻamau mai 2% a 4%. He mea koʻikoʻi kēia waiwai no nā noi e koi ana i ka hoʻolōʻihi pinepine ʻana a me ka hoʻopili ʻana, e like me nā sila a me nā diaphragms.
ʻAila a me ke Kinohi Kūʻē
ʻO kekahi mea maikaʻi ʻē aʻe o ka polyurethane rubber ʻo kona kūpaʻa kiʻekiʻe i ka aila a me nā kemika. ʻOi aku ka maikaʻi o ka lāʻau nitrile i ke kūʻē ʻana i nā ʻaila mineral a ʻoi aku ka maikaʻi o 5 a 6 mau manawa ma mua o ka lāʻau maoli. ʻO kēia ka mea i makemake ʻia no ka hoʻohana ʻana i nā kaiapuni i ʻike ʻia i ka ʻaila, nā wahie, a me nā kemika koʻikoʻi ʻē aʻe.
Nā noi o ka Polyurethane Rubber
ʻOihana Kaʻa
I ka ʻoihana kaʻa, hoʻohana nui ʻia ka polyurethane rubber no ka hana ʻana i nā mea hoʻokuʻu ʻia, nā sila, a me nā gaskets. ʻO kona kūlana haʻahaʻa haʻahaʻa kiʻekiʻe a me ke kūpaʻa ʻana i ka lole e kūpono ia no kēia mau noi. Hoʻohui ʻia, ʻo kona hiki ke kū i nā wela wela e hōʻoia i ka hana pono i nā piʻi wela a me ke anu.
Kūkulu a me nā ʻoihana
Hoʻohana nui ʻia ka polyurethane rubber i ke kūkulu ʻana no nā noi e like me nā dampers vibration, papahele, a me nā uhi. ʻO kona lōʻihi a me ke kū'ēʻana i ka abrasion a me nā kemika e lilo ia i koho hilinaʻi no nā kaiapuni hana paʻakikī. Eia kekahi, ʻo kona maʻalahi e hiki ai iā ia ke komo pono i nā haʻalulu a me nā haʻalulu, e hoʻonui ai i ka lōʻihi o nā hale.
Nā Hana Hana a me nā Hana Hana Hana
I ka hana ʻana, hoʻohana ʻia ka polyurethane rubber i nā kāʻei conveyor, wili, a me nā ʻāpana mīkini. ʻO kona ikaika kiʻekiʻe a me ke kūpaʻa ʻaʻahu e hōʻoia e hiki i kēia mau ʻāpana ke mālama i nā ukana kaumaha a me ka hana mau me ka ʻole o ka hoʻololi pinepine ʻana. ʻAʻole kēia e hōʻemi wale i ka downtime akā hoʻohaʻahaʻa hoʻi i nā kumukūʻai mālama.
Nā mea kūʻai aku
Loaʻa ka polyurethane rubber ma nā mea kūʻai like ʻole, me nā kāmaʻa, nā mea haʻuki, a me nā mea hale. ʻO kona ʻano māmā, i hui pū ʻia me kona kūpaʻa a me ka maʻalahi, e lilo ia i koho kaulana no kēia mau noi. No ka laʻana, hoʻohana ʻia ia i nā wāwae o nā kāmaʻa haʻuki kiʻekiʻe e hāʻawi i ka cushioning a me ke kākoʻo.
Ka hopena
Kūleʻa ka polyurethane rubber ma ke ʻano he mea maʻalahi a hilinaʻi e hoʻokō i nā koi o nā ʻoihana like ʻole. ʻO kāna hui pū ʻana o nā waiwai, me ka ikaika kiʻekiʻe, elasticity, a me ke kūʻē ʻana i ka ʻaʻahu a me nā kemika, lilo ia i mea koho maikaʻi loa no nā noi mai ka automotive a i nā mea kūʻai aku. No ka ʻike hohonu o kāna mau noi a me nā pōmaikaʻi, hiki iā ʻoe ke ʻimi hou aku e pili ana ʻO ka Rubber Polyurethane.
