POMHe thermoplastic semicrystalline ka pepa -C a ua hōʻailona ʻia e kahi coefficient haʻahaʻa o ka friction a me nā waiwai ʻaʻahu maikaʻi, a me nā waiwai ʻaʻahu maikaʻi, ʻaʻole i hoʻopilikia ʻia e nā wahi pulu. Hāʻawi ka papa POM i ke kū'ē maikaʻi i nā ʻano kemika like ʻole me nā mea hoʻoheheʻe he nui. Hāʻawi ka papa Delrin i ka ikaika kiʻekiʻe a me ka paʻakikī i hui pū ʻia me ka maʻalahi o ka mīkini. ʻIke ʻia ʻo AHD no kona ikaika mīkini kiʻekiʻe, ke kū'ē wela a me nā waiwai antifriction maikaʻi. No nā ʻāpana e pono ai ke kūpaʻa ka dimensionally ʻoiai i hōʻike ʻia i ka makū a i ʻole nā wahi pulu, hāʻawi ʻo POM-C i ka wai wela, ka wela a me ke kū'ē kemika ma mua o POM-H.
I ka wā e pili ana i ke kūpaʻa kemika, ʻoi aku ka maikaʻi o nā pepa POM. Loaʻa iā ia ke kūpaʻa kiʻekiʻe i nā mea hoʻoheheʻe, nā wahie, nā aila a me nā kemika ʻē aʻe he nui, e kūpono ai no nā ʻāpana e pili ana i kēia mau mea. Loaʻa i ka pepa POM ke kūpaʻa kiʻekiʻe, ʻo ia hoʻi ke mālama nei i kona ʻano a me nā ana ma lalo o nā kūlana mahana koʻikoʻi.
ʻO kekahi pono o nā pepa POM ʻo ko lākou komo haʻahaʻa i ka makū. ʻAʻole e like me nā plastics ʻē aʻe he nui, he haʻahaʻa loa ka ʻano o ka POM e omo i ka makū, kahi e hoʻopilikia ai i kona mau waiwai mechanical a me ka uila. ʻO kēia ka mea e kūpono ai no ka hoʻohana ʻana i nā wahi pulu kahi e hopohopo ai ka hygroscopicity.

ʻO kekahi o nā hiʻohiʻona koʻikoʻi oPepa POMʻo ia kona mau waiwai paheʻe maikaʻi loa. He haʻahaʻa kona coefficient o ka friction, ʻo ia hoʻi he paheʻe maʻalahi ia ma luna o nā ʻili ʻē aʻe me ka ʻole o ke kū'ē nui. ʻO kēia ka mea e lilo ai ia i koho kaulana no nā noi e pono ai ka neʻe mālie, ʻaʻohe friction, e like me nā kia, nā bearings a me nā ʻāpana paheʻe.
Pepa POMLoaʻa iā ia ke kūpaʻa kiʻekiʻe i ka ʻaʻahu ʻana, he mea koʻikoʻi ia i nā noi e pili ana i nā neʻe mīkini hana hou. Hiki iā ia ke kū i ka ʻaʻahu lōʻihi a me ka friction, e hoʻopaʻa ai. Eia kekahi, ʻaʻole maʻalahi ka POM e kolo, ʻo ia hoʻi ke mālama nei i kona ʻano a me ke kūpaʻa ʻoiai ma lalo o ke kaumaha lōʻihi.
ʻO ka maʻalahi o ka mīkini ʻana kekahi pono o nā pepa POM. Hiki ke maʻalahi ke mīkini ʻia a hana ʻia me ka hoʻohana ʻana i nā kaʻina hana kuʻuna e like me ka wili ʻana, ka huli ʻana a me ka wili ʻana. ʻAe kēia i ka hana maʻalahi o nā ʻāpana paʻakikī a pololei. Loaʻa i ka pepa POM nā waiwai uila a me nā dielectric maikaʻi, e kūpono ai no nā noi insulation uila.
At MA ʻŌʻAO, hāʻawi mākou i kahi ākea o nā koho POM. Hana ʻia kā mākou mau pepa POM mai nā mea puʻupaʻa e hōʻoiaʻiʻo ana i ke kūlana kiʻekiʻe a me ka hana. Loaʻa lākou i nā ʻano mānoanoa like ʻole 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 hoʻopilikino i nā kala e like me kāu mau koi kikoʻī.
Inā makemake ʻoe i nā pepa POM no nā ʻāpana mīkini, nā mea hoʻokaʻawale uila a i ʻole kekahi noi ʻē aʻe, hiki i kā mākou mau pepa POM kiʻekiʻe ke hoʻokō i kāu mau pono. Me ko lākou mau waiwai mechanical maikaʻi loa, ke kūpaʻa kemika kiʻekiʻe a me ke kūpaʻa dimensional, hāʻawi kā mākou mau pepa POM i ka hana maikaʻi loa a me ka hilinaʻi. E kāhea mai iā mākou i kēia lā e aʻo hou e pili ana i kā mākou huahana pepa POM a pehea e hiki ai iā lākou ke pōmaikaʻi i kāu papahana.
