I loko o nā ʻano mīkini ʻoihana, ʻo ka friction a me nā kuʻi ʻana ma waena o nā ʻāpana metala ke kumu nui, e alakaʻi ana i ka ʻaʻahu pono ʻole o nā ʻāpana, ka walaʻau mīkini pinepine, a me nā pōʻaiapuni mālama lōʻihi. No ka hoʻololi ʻana i kēia kūlana, ʻo kahi plastic engineering—ultra-high molecular weight polyethylene (UHMWPE)—ke lilo nei i "lencencer" leo ʻole i loko o nā mīkini ma muli o kāna hana kiʻekiʻe.
ʻO ka hana kiʻekiʻe oPepa UHMWPEmai kona ʻano molekala kū hoʻokahi. Loaʻa i ka UHMWPE nā kaulahao molekala lōʻihi loa, me ke kaumaha molekala ma mua o 1.5 miliona. Hoʻokumu kēia mau kaulahao i hoʻopili ʻia i kahi pūnaewele kūpaʻa loa, e hāʻawi ana iā ia i ʻekolu mau pono koʻikoʻi:
1. Ke Kū'ē ʻana i ka ʻAʻahu: ʻO ke ʻano kaulahao molekala lōʻihi loa o UHMWPE e hāʻawi iā ia i ke kū'ē ʻana i ka ʻaʻahu kiʻekiʻe loa, e kūlana mua ana ma waena o nā plastics a me 6-8 mau manawa o ke kila kalapona a me ke kila kila.
2. Ke Kū'ē i ka Hopena: Hoʻohanohano ka mea UHMWPE i ke kūpaʻa hopena kiʻekiʻe loa ma waena o nā plastik. ʻOiai ma -260 degere Celsius, paʻa mau ia a ʻaʻole palupalu, e kū pono ana i nā hopena.
3. Nā Waiwai Hoʻoluʻu Ponoʻī:Mea UHMWPELoaʻa iā ia kahi coefficient o ka friction me ke kila kalapona ma waena o 0.1 a me 0.2, haʻahaʻa ma mua o ka hapa nui o nā plastics ʻenekinia. Loaʻa iā ia nā waiwai lubrication ponoʻī kūlohelohe. ʻO ka ʻili laumania o nā pepa UHMWPE e pale aku i ka hoʻopili ʻana o nā mea ʻē aʻe, e hana ana i kona pili ʻana me nā ʻili metala e like me ka pahi e holo ana ma luna o ka hau, e koi ana i ka lubrication liʻiliʻi a hoʻemi nui i ka walaʻau i hoʻokumu ʻia e ka friction.
He kuleana koʻikoʻi ko nā pepa mea UHMWPE, nā koʻokoʻo, a me nā ʻāpana i nā ʻāpana mīkini koʻikoʻi:
- Nā Kia a me nā Sprockets
I nā mīkini kuʻuna i hoʻouka māmā ʻia a koʻikoʻi i ka walaʻau, e like me nā mīkini lole, hoʻopau ʻo UHMWPE i ka walaʻau wili a me ka hopena o nā kia kila, e hōʻoiaʻiʻo ana i ka hana maʻalahi a me ka pale ʻana i nā ʻāpana metala.
2. Nā Alanui Alakaʻi a me nā Sliders
He kuleana koʻikoʻi ko nā pepa UHMWPE a me nā ʻāpana mīkini maʻamau ʻole mai nā mea CNCUHMWPE i nā paheʻe kāʻei conveyor a me nā ʻūlū hale kūʻai, e hōʻemi ana i ke kū'ē ʻana o ka neʻe, e hoʻohaʻahaʻa ana i ka hoʻohana ʻana i ka ikehu, a e hāʻawi ana i ka hana mālie a mālie.
3. Nā Bearings a me nā Bushings
He kūpono loa nā bearings UHMWPE i nā wahi wikiwiki haʻahaʻa a kaumaha kahi e paʻakikī ai ka lubrication a i ʻole he mea hopohopo ka haumia o ka aila, e like me nā lako hana meaʻai, nā lako ʻōmole pia, nā hale hana mālama wai, a me nā mīkini mahiʻai.
4. Nā Liner a me nā pepa pale-ʻaʻahu
I nā ʻōnaehana lawe mea no nā ores, lanahu, a me nā palaoa, ke kū nei nā uhi o nā silos a me nā chutes i ka hao nui.Pepa uhi UHMWPE, me ko lākou coefficient haʻahaʻa loa o ka friction a me nā waiwai non-stick, pale maikaʻi i ka pale ʻana o nā mea a hōʻoia i ke kahe maʻalahi o nā mea.
I ka hoʻolālā mīkini o kēia au, ka mea e hoʻokau mua ana i ka pono kiʻekiʻe, ka mālama ikehu, a me ke aloha i ke kaiapuni (haʻahaʻa ka walaʻau), ʻaʻole wale ka mea UHMWPE e hoʻoponopono i ka pilikia o ka walaʻau mīkini akā hoʻomaikaʻi pū i ka hana holoʻokoʻa o nā lako mīkini.
MA ʻŌʻAOʻO ka hana ʻana o nā pepa UHMWPE a me nā ʻāpana mīkini CNC maʻamau ʻole e hoʻokele ana i ka ʻoihana hou i ka ʻoi aku ka maikaʻi, ka launa pū ʻana me ke kaiapuni, a me ke kūpaʻa ma ke ʻano kū hoʻokahi.
