ʻO nā mea hana CNC
ʻO ka mīkini CNC ma POM
ʻO nā plastics kekahi mea maʻamau i hoʻohana ʻia i ka huli ʻana o CNC no ka mea aia lākou i nā koho ʻokoʻa he nui, ʻoi aku ka inexpensive, a ʻoi aku ka wikiwiki o ka manawa machining.ʻO nā plastics maʻamau i hoʻohana ʻia me ABS, acrylic, polycarbonate a me nylon.
ʻO ka wehewehe ʻana o POM (Polyoxymethylene).
ʻO POM, i kapa ʻia ʻo acetal a i ʻole Delrin, he mea thermoplastic me nā waiwai semi-crystalline.Manaʻo nui ʻia no kona ikaika ʻokoʻa, ʻoʻoleʻa a me nā waiwai friction haʻahaʻa.Hoʻohana pinepine ʻia ka POM i nā noi e koi ana i ka pololei a me nā ʻāpana friction haʻahaʻa.
Palapala noi
ʻO POM, i kapa ʻia ʻo acetal a i ʻole Delrin, kahi mea thermoplastic versatile i hoʻohana ʻia i nā ʻano noi like ʻole.ʻO kāna mau waiwai kūikawā he mea kūpono ia no ka hana ʻana i nā mea hana a me nā bearings i nā ʻōnaehana mechanical.ʻO nā ʻāpana kaʻa, e like me nā ʻāpana ʻōnaehana wahie a me nā ʻoki o loko, e pōmaikaʻi hoʻi i ka lōʻihi o ka POM a me ke kūpaʻa.Eia kekahi, kūpono nā waiwai insulating uila maikaʻi o POM no ka hoʻohana ʻana i nā mea hoʻohui uila.ʻO ka mea hope loa, ʻo ka ikaika a me ka lōʻihi o POM ka mea i koho ʻia no ka hana ʻana i nā mea kūʻai aku e like me nā zippers, nā mea pāʻani a me nā lako kīhini.
Nā ikaika
Loaʻa ka ikaika o ka mea a hiki ke kū i nā ikaika mechanical.Hāʻawi ia i ka neʻe maʻemaʻe me ka liʻiliʻi liʻiliʻi a kūpaʻa i ka ʻaʻahu.Mālama ʻo ia i kona ʻano a me nā ana i nā kūlana āpau, e hōʻoia ana i ka paʻa.Eia kekahi, kū'ē ia i nā hopena o nā kemika a hiki ke pale i ka ʻike ʻana i nā ʻano mea like ʻole me ka ʻole o ka hōʻino.
Nawaliwali
He kūʻokoʻa ka waiwai i ka radiation UV a no laila hiki ke hoʻopōʻino i ka wā lōʻihi o ka ʻike ʻana i ka lā.Eia kekahi, hiki ke hoʻoikaika i nā māwae ma lalo o kekahi mau kūlana.

ʻIke ʻepekema kaulana e pili ana i ka POM
ʻO POM (Polyoxymethylene), i ʻike ʻia ʻo acetal, he plastik ʻenehana hana kiʻekiʻe.He thermoplastic semi-crystalline e hāʻawi ana i ka ikaika mechanical maikaʻi, ʻoʻoleʻa, a me ke kūpaʻa dimensional.Hoʻohana pinepine ʻia ka POM i nā ʻāpana kikoʻī, e like me nā gears, bearings, a me nā ʻāpana automotive.
He haʻahaʻa haʻahaʻa haʻahaʻa ko POM, kahi e kūpono ai i nā noi e pono ai ke kapa haʻahaʻa a me ka friction.He kūpaʻa maikaʻi ʻo ia i nā kemika, nā mea hoʻoheheʻe, a me nā wahie, kūpono ia no nā noi i nā ʻoihana kaʻa a me nā ʻoihana.Loaʻa i ka POM nā waiwai insulation uila maikaʻi a hiki ke kū i nā wela kiʻekiʻe.
Loaʻa ka POM i ʻelua ʻano nui: homopolymer a me copolymer.Hāʻawi ka Homopolymer POM i ka ikaika a me ka ʻoʻoleʻa kiʻekiʻe, ʻoiai ʻo copolymer POM e hāʻawi i ka pale maikaʻi i ka hoʻohaʻahaʻa ʻana i ka wela a me ka hoʻouka kemika.
