POMʻO ka pepa C he semicrystalline thermoplastic a ua ʻike ʻia e ka haʻahaʻa haʻahaʻa o ka friction a me nā waiwai ʻaʻahu maikaʻi, a me nā waiwai ʻaʻahu maikaʻi, ʻaʻole i hoʻopili ʻia e nā ʻona wai. Hāʻawi kahi pā Delrin i ka ikaika kiʻekiʻe a me ka paʻakikī i hui pū ʻia me ka mīkini maʻalahi. Hoʻomaopopo pū ʻia ʻo AHD no kona ikaika me-chanical kiʻekiʻe, ka pale wela a me nā waiwai antifriction maikaʻi. A No nā ʻāpana pono e paʻa i ka nui a i ʻike ʻia i ka haʻahaʻa a i ʻole ka ʻāina pulu, hāʻawi ʻo POM-C i ka wai wela, ka wela a me ka pale kemika ma mua o POM-H.
I ka hiki ʻana i ke kūʻē kemika, ʻoi aku ka maikaʻi o nā lau POM. He kūpaʻa kiʻekiʻe ʻo ia i nā solvents, nā wahie, nā aila a me nā mea ʻē aʻe he nui, i mea kūpono no nā ʻāpana e pili ana i kēia mau mea. Loaʻa i ka pepa POM ke kūpaʻa kiʻekiʻe, ʻo ia ka mea e paʻa i kona ʻano a me nā ana ma lalo o nā kūlana wela.
ʻO kekahi pōmaikaʻi ʻē aʻe o nā lau POM ʻo ko lākou haʻahaʻa haʻahaʻa haʻahaʻa. ʻAʻole e like me nā plastics ʻē aʻe, he haʻahaʻa haʻahaʻa loa ka POM e hoʻomoʻa i ka makū, e pili ana i kāna mau mea mechanical a me ka uila. He mea kūpono kēia no ka hoʻohana ʻana i nā wahi haʻahaʻa kahi e hopohopo ai ka hygroscopicity.

ʻO kekahi o nā hiʻohiʻona koʻikoʻi oPepa POMʻo ia kona mau waiwai hoʻoheheʻe maikaʻi loa. He haʻahaʻa haʻahaʻa ia o ka friction, ʻo ia hoʻi ke paheʻe maʻalahi ma luna o nā ʻili ʻē aʻe me ke kūʻē ʻole. He koho kaulana kēia no nā noi e koi ana i ka neʻe ʻana i ka neʻe maʻemaʻe, friction-free, e like me nā gears, bearings a me nā ʻāpana sliding.
Pepa POMs loaʻa nō hoʻi ke kūpaʻa ʻaʻahu kiʻekiʻe, he mea koʻikoʻi i nā noi e pili ana i nā neʻe mechanical repetitive. Hiki iā ia ke pale i ka ʻaʻahu lōʻihi a me ka friction, e paʻa ai. Eia kekahi, ʻaʻole hiki i ka POM ke kolo, ʻo ia ka mea e paʻa i kona ʻano a me kona kūpaʻa ʻoiai ma lalo o ke koʻikoʻi lōʻihi.
ʻO ka machinability kekahi pono o nā pepa POM. Hiki ke maʻalahi a hana ʻia me ka hoʻohana ʻana i nā kaʻina hana kuʻuna e like me ka wili, ka huli ʻana a me ka wili. ʻAe kēia i ka hana maʻalahi o nā ʻāpana paʻakikī a pololei. Loaʻa i ka pepa POM nā waiwai uila a me dielectric maikaʻi, e kūpono ana i nā noi insulation uila.
At MAO aku, hāʻawi mākou i kahi ākea o nā koho POM. Hana ʻia kā mākou pepa POM mai nā mea puʻupaʻa e hōʻoiaʻiʻo ana i ka maikaʻi a me ka hana. Loaʻa iā lākou ma kahi ākea o nā mānoanoa mai 0.5mm a 200mm, me ka laulā maʻamau o 1000mm a me ka lōʻihi o 2000mm. Hāʻawi mākou i nā kala keʻokeʻo a me ka ʻeleʻele, a i ʻole hiki iā mākou ke hana i nā kala e like me kāu mau koi kikoʻī.
Inā makemake ʻoe i nā pepa POM no nā ʻāpana mechanical, nā insulators uila a i ʻole nā noi ʻē aʻe, hiki i kā mākou pepa POM kiʻekiʻe ke hoʻokō i kāu mau pono. Me kā lākou mau waiwai mechanical maikaʻi loa, ke kūpaʻa kemika kiʻekiʻe a me ke kūpaʻa dimensional, hāʻawi kā mākou pepa POM i ka hana koʻikoʻi a me ka hilinaʻi. E kelepona mai iā mākou i kēia lā e aʻo hou aʻe e pili ana i kā mākou huahana pepa POM a pehea e hiki ai iā lākou ke pōmaikaʻi i kāu papahana.
