Pamwamba Chithandizo cha Maginito
The pamwamba mankhwala aneodymium maginitoamatenga gawo lalikulu pakuchita kwawo komanso moyo wautali. Maginito a Neodymium, omwe amadziwikanso kuti maginito a NdFeB, ndi maginito amphamvu kwambiri okhazikika opangidwa kuchokera ku alloy ya iron, boron, ndi neodymium. Chithandizo chapamwamba chimatanthawuza njira yogwiritsira ntchito wosanjikiza kapena wokutira pamwamba pa maginito a neodymium. Mankhwalawa ndi ofunikira kuti maginito asawonongeke komanso kuti azitha kukhazikika. Mitundu yodziwika bwino yamankhwala apamtunda a maginito a neodymium ndi monga NiCuNi plating, Zinc plating, ndi zokutira za Epoxy.
Chimodzi mwazifukwa zazikulu zomwe chithandizo chapamwamba chilili chofunikira kwa maginito a neodymium ndikuti amatha kuwononga dzimbiri. Maginito a Neodymium amapangidwa ndi chitsulo, chomwe chimakonda kuchita dzimbiri chikakhala ndi chinyezi ndi mpweya. Pogwiritsa ntchito zokutira zoteteza, dzimbiri zimatha kuchepetsedwa kwambiri, kukulitsa moyo wa maginito.
Chifukwa china chochizira pamwamba ndikuwonjezera magwiridwe antchito a maginito. Chophimbacho chingapereke malo osalala, kuchepetsa kukangana ndi kulola kuti maginito apangidwe bwino. Njira zina zochizira pamwamba, monga plating ya faifi tambala kapena plating ya golide, zimatha kupangitsa kuti maginito asagwire kutentha kwambiri, ndikupangitsa kuti ikhale yoyenera kugwiritsa ntchito monga kutentha. Zochizira zam'mwamba zimathandiziranso maginito a neodymium kuti azigwirizana ndi madera osiyanasiyana ndikugwiritsa ntchito. Mwachitsanzo, zokutira za epoxy zimatha kupereka kutchinjiriza, kulola kuti maginito agwiritsidwe ntchito pamagetsi popanda kufupikitsa. Zopaka zimathanso kuteteza maginito ku mankhwala kapena ma abrasion, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito m'malo ochita dzimbiri kapena pamalo pomwe pali mikangano ndi kuvala.
Thandizo lapamtunda ndilofunika kuti maginito a neodymium atetezedwe ku dzimbiri, kupititsa patsogolo magwiridwe antchito, kukulitsa kulimba, ndikuwonetsetsa kuti kumagwirizana ndi malo ndi ntchito zina. Pogwiritsa ntchito chithandizo choyenera chapamtunda, nthawi yamoyo komanso mphamvu ya maginito a neodymium imatha kusintha kwambiri.
Pansipa pali mndandanda wa zokutira / zokutira ndi nthenga zake kuti mufotokozere.

Mitundu ya zokutira za maginito
NiCuNi: Chophimba cha nickel chimapangidwa ndi zigawo zitatu, nickel-copper-nickel. Kupaka kwamtunduwu ndi komwe kumagwiritsidwa ntchito kwambiri ndipo kumapereka chitetezo ku dzimbiri la maginito panja. Ndalama zoyendetsera ntchito ndizotsika. Kutentha kwakukulu kogwira ntchito ndi pafupifupi 220-240ºC (malingana ndi kutentha kwakukulu kwa maginito). Kupaka kwamtunduwu kumagwiritsidwa ntchito m'mainjini, majenereta, zida zamankhwala, masensa, magalimoto, kusungirako, njira zowonda zamakanema, ndi mapampu.
Black Nickel: Zomwe zimapangidwira izi ndizofanana ndi zazitsulo za nickel, ndi kusiyana komwe kumapangidwira njira yowonjezera, msonkhano wakuda wa nickel. Katundu ndi ofanana ndi wamba nickel plating; makamaka kuti chophimbachi chimagwiritsidwa ntchito pazinthu zomwe zimafuna kuti mawonekedwe a chidutswacho asakhale owala.
Golide: Kupaka kwamtunduwu nthawi zambiri kumagwiritsidwa ntchito m'chipatala komanso ndikuyenera kugwiritsidwa ntchito pokhudzana ndi thupi la munthu. Pali chivomerezo chochokera ku FDA (Food and Drug Administration). Pansi pa zokutira golide, pali gawo laling'ono la Ni-Cu-Ni. Kutentha kwakukulu kogwira ntchito kumakhalanso pafupifupi 200 ° C. Kuwonjezera pa munda wa mankhwala, golide plating amagwiritsidwanso ntchito zodzikongoletsera ndi zokongoletsera.
Zinc: Ngati kutentha kwakukulu kogwira ntchito kuli kosakwana 120 ° C, mtundu uwu wa ❖ kuyanika ndi wokwanira. Mtengo wake ndi wotsika ndipo maginito amatetezedwa ku dzimbiri panja. Itha kumamatidwa kuchitsulo, ngakhale zomatira zopangidwa mwapadera ziyenera kugwiritsidwa ntchito. Kupaka kwa zinki kuli koyenera malinga ngati zotchinga zoteteza maginito ndizochepa komanso kutentha kocheperako kumapitilira.
Parylene: Chophimba ichi chimavomerezedwanso ndi FDA. Chifukwa chake, amagwiritsidwa ntchito pazachipatala m'thupi la munthu. Kutentha kwakukulu kogwira ntchito kumakhala pafupifupi 150 ° C. Mapangidwe a mamolekyu amakhala ndi ma hydrocarbon opangidwa ndi mphete omwe ali ndi H, Cl, ndi F. Malingana ndi kapangidwe ka maselo, mitundu yosiyanasiyana imasiyanitsidwa monga Parylene N, Parylene C, Parylene D, ndi Parylene HT.
Epoxy: Chophimba chomwe chimapereka chotchinga chabwino kwambiri polimbana ndi mchere ndi madzi. Pali kumamatira kwabwino kwambiri kuchitsulo, ngati maginito amamatira ndi zomatira zapadera zoyenera maginito. Kutentha kwakukulu kogwira ntchito kumakhala pafupifupi 150 ° C. Zovala za epoxy nthawi zambiri zimakhala zakuda, koma zimatha kukhala zoyera. Mapulogalamu atha kupezeka m'magulu am'madzi, mainjini, masensa, katundu wa ogula, ndi gawo lamagalimoto.
Maginito ojambulidwa mu pulasitiki: amatchedwanso over-molded. Chikhalidwe chake chachikulu ndikuteteza kwake kwabwino kwa maginito kuti asasweka, kuwononga, komanso dzimbiri. Chophimba chotetezera chimapereka chitetezo ku madzi ndi mchere. Kutentha kwakukulu kogwira ntchito kumadalira pulasitiki yogwiritsidwa ntchito (acrylonitrile-butadiene-styrene).
Anapanga PTFE (Teflon): Monga jekeseni / zokutira pulasitiki kumaperekanso chitetezo chabwino kwambiri cha maginito pakusweka, kukhudzidwa, ndi dzimbiri. Maginito amatetezedwa ku chinyezi, madzi, ndi mchere. Kutentha kwakukulu kogwira ntchito kuli pafupi ndi 250 ° C. Chophimba ichi chimagwiritsidwa ntchito makamaka m'mafakitale azachipatala komanso m'makampani ogulitsa zakudya.
Mpira: Kupaka mphira kumateteza mwangwiro kusweka ndi kukhudzidwa komanso kumachepetsa dzimbiri. Zida za rabara zimapanga kukana kwabwino kwambiri pazitsulo zachitsulo. Kutentha kwakukulu kogwira ntchito kuli pafupi ndi 80-100 ° C. Maginito a mphika okhala ndi mphira wa rabara ndi zinthu zoonekeratu komanso zogwiritsidwa ntchito kwambiri.
Timapatsa makasitomala athu upangiri waukadaulo ndi mayankho amomwe angatetezere maginito awo ndikupeza kugwiritsa ntchito bwino maginito.Lumikizanani nafendipo tidzakhala okondwa kuyankha funso lanu.
