Ukonga kwangempela kusekugwemeni emgodini ongenamkhawulo wokwethulwa okuhlulekile. Indlela ethembekile kuphela ingqondo yokuhlola okungabazayo nokuhlelekile.

I-Game-Changer: Kungani i-Flexible NdFeB inqoba i-Ferrite

Sekuyiminyaka, “imagnethi eguquguqukayo” yayisho into eyodwa:i-ferrite. Lezi zingxube ze-ceramic-particle-in-raber/vinyl zisebenza emisebenzini engaguquki, enamandla amancane—njengokubamba iflaya esiqandisini. Kodwa azakhelwe ukunamathela kobungcweti, okugobile lapho ukwehluleka kungeyona inketho.

Ezingeni lobungcweti, lobu buchwepheshe buhlanganisa ama-microparticle e-neodymium (NdFeB) akhiwe ngendlela ethuthukisiwe kuma-polymer substrates afana ne-PVC noma ama-elastomer akhethekile. Le nqubo iletha ukuthuthuka kokusebenza, hhayi nje ukuthuthukiswa okuncane. Isici sayo esivelele amandla okubamba akhethekile esiwafinyelela nge-millimeter yobukhulu. Ngokwesimo esingokoqobo, umugqa ongu-0.6mm ubukhulu ubonisa ukubamba okunamandla, okuqhubekayo ebusweni bensimbi obuqinile, obuqondile—isimo lapho i-magnet ye-ferrite evamile engu-2mm ingahluleka ukunamathela. Lokhu kugxuma kokusebenza kunikeza abaklami inkululeko yokudala izinhlelo zokusebenza ezinhle, eziphansi ezigcina ukubamba okuqinile ezimeni ezigobile nezingavamile.

Ukuzulazula Ezingxoxweni: Imibuzo Emi-5 Ebalulekile Yezinto Ongazethemba

Imininingwane yomhlinzeki ebhalwe ohlwini kufanele ibhekwe njengesiqalo sengxoxo, hhayi isiqinisekiso esiqinisekile sokuthi umkhiqizo uzosebenza kanjani.

Ukuze uthole ukukhetha okunolwazi olunembile, beka eceleni okuqukethwe okukhazimulayo kokuphromotha bese uhlola lezi zindawo ezibalulekile zokuhlola:

1. Kudingeka Ubufakazi, Hhayi Izithembiso, Bamandla Kamagnetic. Amagama angacacile njengokuthi "aqinile kakhulu" awasho lutho. Kumelwe uthole izitifiketi zokulinganisa ubuso be-Gauss zangempela zenhlanganisela eqondile kanye nobukhulu obuhlolayo. Ifektri enekhono iqhuba lezi zivivinyo ngaphakathi futhi kufanele inikeze imibiko yesikhathi. Imininingwane ecacile izosho okuthile okufana nalokhu: I-Batch Certified: 680-720 Gauss surface field 0.75mm thickness. Unganqikazi ukubuza mayelana nemvamisa yokuhlola kanye nendlela yabo kulo lonke umqulu wokukhiqiza—kukhuluma kakhulu ngokulawulwa kwenqubo yabo.

2. Ukubekezelela Ubukhulu Bokuhlola Ngokucophelela Komgcini-zimali Ogxile Emininingwaneni. Abaphakeli bashesha ukufaka ubuningi obumaphakathi—0.5mm, 1.0mm, njalo njalo—kodwa ukubamba kwangempela kusebangeni lokubekezelela. Ekusethweni kokuguqula okusheshayo, ukubekezelela okungu-±0.12mm kwenza umehluko omkhulu uma kuqhathaniswa nomkhawulo oqinile ongu-±0.04mm.

Igeyiji engaguquki izodala umonakalo emizileni yokusika ngokuzenzakalelayo, ukusika ngokuqabulana, kanye neyokusonga, okuholela emishinini evalekile, ezinkingeni zokunamathela, kanye nokungcola okumangalisayo. Omunye wabalingani bethu wakuthola lokhu ngendlela enzima lapho ubukhulu obuguquguqukayo emqulwini bubangela ukuthi izingxenye zabo ezisikiwe ngokunemba zibe nokukhipha okunamathelayo okungaguquki, okuphoqele umsebenzi wokusindisa ngemuva kokukhiqiza.
