Lapaʻau ʻili o nā Magnet
ʻO ka lapaʻau ʻili oneodymium magnetshe kuleana koʻikoʻi i kā lākou hana a me ka lōʻihi.ʻO nā mākēneki Neodymium, i kapa ʻia ʻo NdFeB magnets, he mau mākēneki ikaika loa i hana ʻia mai ka hao, boron, a me neodymium.ʻO ka mālama ʻana i ka ʻili e pili ana i ke kaʻina hana o ka hoʻopili ʻana i kahi papa pale a i ʻole ka uhi ʻana i ka ʻili o waho o ka magnet neodymium.Pono kēia lapaʻau no ka pale ʻana i ka magnet mai ka ʻino a hoʻomaikaʻi i kona paʻa holoʻokoʻa.ʻO nā ʻano lapaʻau maʻamau maʻamau no nā magnet neodymium e komo pū me NiCuNi plating, Zinc plating, a me ka uhi Epoxy.
ʻO kekahi o nā kumu nui ke kumu nui o ka mālama ʻana i ka ʻili no nā magnet neodymium ʻo ko lākou hiki ke hoʻopōʻino.Hoʻokumu mua ʻia nā mea magnet Neodymium me ka hao, a hiki i ka pala ke ʻike ʻia i ka wai a me ka oxygen.Ma ka hoʻohana ʻana i kahi uhi pale, hiki ke hoʻemi nui ʻia ka corrosion, e hoʻonui i ke ola o ka magnet.
ʻO ke kumu ʻē aʻe o ka hoʻomaʻamaʻa ʻana i ka ʻili no ka hoʻonui ʻana i ka hana a ka magnet.Hiki i ka uhi ke hāʻawi i kahi ʻili maʻalahi, e hōʻemi ana i ka friction a e ʻae i nā waiwai magnetic ʻoi aku ka maikaʻi.Hiki ke hoʻomaikaʻi i ka pale ʻana o ka magnet i nā wela kiʻekiʻe, e like me ka nickel plating a i ʻole ka plating gula, i kūpono no nā noi e pili ana i ka wela.Hiki i nā lāʻau lapaʻau ke kūpono i nā neodymium magnets me nā kaiapuni a me nā noi.No ka laʻana, hiki i nā uhi epoxy ke hāʻawi i ka insulation, e ʻae i ka magnet e hoʻohana ʻia i nā noi uila me ka ʻole o ka pōkole.Hiki i nā pale ke pale aku i ka magnet mai nā kemika a i ʻole ka abrasion, i kūpono ia no ka hoʻohana ʻana i nā kaiapuni corrosive a i nā noi i loaʻa ka friction a me ka lole.
Pono nā lāʻau lapaʻau no nā neodymium magnets e pale aku i ka corrosion, hoʻomaikaʻi i ka hana, hoʻonui i ka lōʻihi, a hōʻoia i ka hoʻohālikelike ʻana me nā wahi kikoʻī a me nā noi.Ma ka hoʻohana ʻana i ka lāʻau lapaʻau kūpono, hiki ke hoʻomaikaʻi maikaʻi ʻia ke ola a me ka pono o nā magnet neodymium.
Aia ma lalo iho kahi papa inoa o ka uhi ʻana a me ko lākou mau hulu no kāu kuhikuhi.

Ma muli o ke ʻano molekala, ʻokoʻa nā ʻano like ʻole e like me Parylene N, Parylene C, Parylene D, a me Parylene HT.
Epoxy: He uhi e hāʻawi i kahi pale maikaʻi loa i ka paʻakai a me ka wai.Aia kahi adhesion maikaʻi loa i ke kila, inā hoʻopili ʻia ka magnet me kahi mea hoʻopili kūikawā kūpono no nā magnet.ʻO ka mahana hana kiʻekiʻe ma kahi o 150 ° C. ʻO ka maʻamau o ka epoxy coatings he ʻeleʻele, akā hiki ke keʻokeʻo.Hiki ke loaʻa nā noi ma ka ʻāpana moana, nā ʻenekini, nā mea ʻike, nā mea kūʻai aku, a me ka ʻāpana kaʻa.
Hoʻokomo ʻia nā mākēneki i loko o ka plastic: ua kapa ʻia hoʻi ʻo over-molded.ʻO kāna hiʻohiʻona nui ka pale maikaʻi loa o ka magnet mai ka haki ʻana, ka hopena, a me ka corrosion.Hāʻawi ka papa pale i ka pale mai ka wai a me ka paʻakai.ʻO ka mahana hana kiʻekiʻe e pili ana i ka plastic i hoʻohana ʻia (acrylonitrile-butadiene-styrene).
Hoʻokumu ʻia ka PTFE (Teflon): E like me ka injected / plastic coating, hāʻawi pū kekahi i ka pale maikaʻi loa o ka magnet i ka haki ʻana, nā hopena, a me ka corrosion.Mālama ʻia ka magnet mai ka makū, ka wai, a me ka paʻakai.ʻO ka mahana hana kiʻekiʻe loa ma kahi o 250 ° C. Hoʻohana nui ʻia kēia uhi i nā ʻoihana olakino a me ka ʻoihana meaʻai.
Lapa: Mālama maikaʻi ka uhi ʻana mai ka haki ʻana a me nā hopena a hōʻemi i ka ʻino.Hoʻopuka ka mea hao i ka pale paheʻe maikaʻi loa ma nā ʻili kila.ʻO ka mahana hana kiʻekiʻe loa ma kahi o 80-100 ° C. ʻO nā mea magnet pot me ka uhi ʻana i ka lāʻau ka mea ʻike a hoʻohana nui ʻia.
