Ganizirani za ziwonetsero zamalonda (kusinthana pakati pa kukhazikitsa zikwangwani mbali imodzi ndi zosungira zowonetsera mbali ziwiri) kapena mapulojekiti a DIY okhala ndi zosowa zosiyanasiyana.

Mtengo & Kukhalitsa

Maginito a mbali imodzi ndi omwe amawononga ndalama zambiri—mapangidwe osavuta, komanso otsika mtengo opangira. Maginito a neodymium a mbali ziwiri amawononga ndalama zokwana 15-30% chifukwa cha maginito olondola komanso zinthu za substrate, koma ndi ofunika kwambiri pa ntchito zapadera. Maginito awiri pa 1 ndi okwera mtengo kwambiri, chifukwa cha ziwalo zawo zosuntha—ndipo ziwalo zimenezo zimatha kutha pakapita nthawi, makamaka m'malo ovuta (monga chinyezi, fumbi, kapena kutentha kwambiri).

Kumbukirani: Kutentha ndi koopsa kwambiri pa maginito onse a neodymium. Maginito a neodymium okhala ndi mbali ziwiri amatha kutentha mpaka 80°C (176°F); ngati mukuwagwiritsa ntchito pafupi ndi malo olumikizirana kapena malo olumikizirana injini, gwiritsani ntchito maginito a simenti kuti muzitha kutentha kwambiri. Maginito okhala ndi mbali imodzi ali ndi malire ofanana a kutentha, pomwe awiri mwa 1 amatha kulephera msanga kutentha chifukwa cha zinthu zawo zapulasitiki.

Chigamulo: Siyani Kufunafuna “Chabwino Kwambiri”—Sankhani Choyenera

Palibe "wopambana" wa onse pano—koma ndi chikoka choyenera pantchito yanu yeniyeni. Tiyeni tichepetse:

Sankhani chovala cha mbali imodzi ngati mukufuna mphamvu yayikulu ya pamwamba pa chinthu chimodzi ndipo mukufuna kupewa kukopa mbali. Ndi chisankho chosavuta kugwiritsa ntchito m'masitolo ambiri amafakitale.

Sankhani neodymium yokhala ndi mbali ziwiri ngati mukufuna kuyanjana kwa malo awiri (kugwirizira magawo awiri pamodzi, kuthamangitsa, kapena kuchita zinthu ziwiri). Ndi njira yosinthira zinthu pakupanga, zamagetsi, ndi zida zanzeru zakunyumba.

Sankhani ziwiri mwa chimodzi pokhapokha ngati kugwiritsa ntchito zinthu zosiyanasiyana sikungatheke kukambirana, ndipo mukufunitsitsa kutaya mphamvu ndi kulimba. Ndi chida chapadera, osati cholowa m'malo mwa maginito apadera.

Malangizo Omaliza a Akatswiri (Kuchokera ku Maphunziro Ovuta)

1. Yesani musanayitanitse zinthu zambiri. Ndinavomereza kale kuti maginito a neodymium okhala ndi mbali ziwiri akhale ndi mayunitsi 5,000 popanda kuyesa m'nyumba yosungiramo zinthu yonyowa ya kasitomala—zophimba zomwe zinachita dzimbiri zinawononga 20% ya gulu lonselo. Zophimba za epoxy zimaposa zophimba za nickel m'malo ovuta.

2. Musamawonjezere mphamvu. Maginito a N52 okhala ndi mbali ziwiri amamveka bwino, koma ndi ofooka. Pa ntchito zambiri, N42 ndi yamphamvu (m'machitidwe) ndipo imakhala nthawi yayitali.

3. Chitetezo choyamba. Maginito onse a neodymium ndi olimba—okhala ndi mbali ziwiri amatha kukanikiza zala kapena kupukuta makiyi achitetezo kutali ndi mapazi. Sungani kutali ndi zamagetsi ndipo gwiritsani ntchito magolovesi mukamagwira ntchito.

Mwachidule, chisankho chabwino kwambiri chimatsatira mfundo yakuti "mawonekedwe amatsatira ntchito." Lolani kuti ntchito yanu yeniyeni iwonetse ngati maginito a neodymium okhala ndi mbali imodzi, mbali ziwiri, kapena hybrid 2-in-1 neodymium ndi abwino kwambiri—cholinga chake ndi kukwaniritsa zotsatira zomwe mukufuna popanda kusokoneza.
