Polyoxymethylene (POM) he ʻano ʻenekinia plastic me ka hana maikaʻi loa, ʻike ʻia ma waho ʻo "Duracon" a me "Super Steel". Loaʻa i ka POM kiʻekiʻe ka paʻakikī, ka ikaika a me ka rigidity e like me ka metala. Loaʻa iā ia ka lubrication ponoʻī maikaʻi, ke kūpaʻa luhi maikaʻi a me ka elasticity i kahi ākea o ka mahana a me ka haʻahaʻa. Eia kekahi, loaʻa iā ia ke kūpaʻa kemika maikaʻi. Ua hoʻolauna ʻo Ruiyuan Engineering Plastics i ka POM kiʻekiʻe e kū i ka ʻaʻahu ma ke kumu kūʻai haʻahaʻa ma mua o ka nui o nā plastik ʻenekinia ʻē aʻe. Ke hoʻololi nei ia i kekahi mau mākeke i noho mau ʻia e nā metala, e like me ke pani ʻana i ka zinc, keleawe, aluminika a me ke kila e hana i nā ʻāpana he nui. Mai kona hiʻohiʻona, ua hoʻohana nui ʻia ka POM kiʻekiʻe i ka uila, nā mīkini, nā hiʻohiʻona, nā ʻoihana māmā i kēlā me kēia lā, nā kaʻa, nā mea kūkulu hale, nā mahiʻai a me nā ʻano ʻē aʻe. I loko o nā ʻano noiʻi hou he nui, e like me ka ʻenehana lapaʻau, nā hāmeʻa haʻuki, a me nā mea ʻē aʻe, hōʻike pū ʻia ka POM kūʻokoʻa kiʻekiʻe i kahi ʻano ulu maikaʻi.
ʻO nā hiʻohiʻona POM hiki ke ʻaʻahu kiʻekiʻe:
1. ʻO ka POM kiʻekiʻe i ka ʻaʻahu kūʻokoʻa he ʻilika aniani me kahi helu heheʻe ʻokoʻa. Ke hiki i ka helu heheʻe, emi koke ka viscosity heheʻe.
2. Loaʻa i ka POM kiʻekiʻe ka hoʻopaʻa ʻana i ka haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa geometric maikaʻi, a kūpono loa ia no ka hana ʻana i nā mea hana a me nā bearings.
3. ʻO ka POM kiʻekiʻe aʻaʻahu kū'ē i ka wela kiʻekiʻe, no laila ua hoʻohanaʻia i nā mea paipu (pipeline valves, pump houses), lawn equipment, etc.
4. He mea paakiki a elastic ka POM aahu ki'eki'e.
5. ʻO ke kiʻekiʻe kiʻekiʻe o ka crystallization o ke kiʻekiʻe o ka lole-kūpono POM alakaʻi i kahi kiʻekiʻe kiʻekiʻe shrinkage rate, hiki ke piʻi i kahi kiʻekiʻe e like me 2% a 3.5%. Loaʻa nā uku pōkole ʻokoʻa no nā ʻikepili i hoʻonui ʻia
I ka wā e pili ana i ka pale kemika,Pepa POMs maikaʻi. 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.
