1. Isingeniso: Iqhawe Elingadunyiswa Lokusungula Izinto Ezintsha Kwezokwelapha—Ama-Neodymium Magnets Angokwezifiso

Ezweni lobuchwepheshe bezokwelapha elishintsha ngokushesha,omaginethi be-neodymium ngokwezifisobathuthukisa buthule intuthuko entsha. Kusukela kuma-scanner e-MRI anesinqumo esiphezulu kuya kumarobhothi okuhlinza angangenisi kakhulu, la ma-magnet amancane kodwa anamandla kakhulu achaza kabusha lokho okungenzeka ekunakekelweni kwezempilo.

Omaginethi be-Neodymium—abayingxenye yomndeni wamaginethi angavamile—banamandla amakhulu afinyelela ku-10 kunamaginethi e-ferrite endabuko. Lokhu kuvumela onjiniyela ukuthi baklameamadivayisi ezokwelapha amancane, alulangaphandle kokulahlekelwa ukusebenza kahle. Isibonelo, i-magnet ye-neodymium engangemali ingavumela ukuhambisana okunembile kwezinzwa kuma-monitor e-glucose aphathwayo, kuyilaphoizembozo ezihambisana ne-bioqinisekisa ukusetshenziswa okuphephile, kwesikhathi eside kumadivayisi afakelwa njenge-pacemaker.

Njengoba isidingo sezinqubo ezingangenisi kakhulu kanye nokwelashwa okwenziwe ngezifiso sikhula, nesidingo sokubaizingxenye ezisebenza ngogesi ezithembekile nezinembileLesi sihloko sihlola indlela omaginethi be-neodymium abangokwezifiso abaqhuba ngayo ukusungula izinto ezintsha kwezokwelapha futhi sinikeza ukuqonda okusebenzayo kubaklami nonjiniyela.

2. Kungani Kusetshenziswa Ama-Neodymium Magnets? Izinzuzo Ezintathu Eziyinhloko Zamadivayisi Ezokwelapha

A. Amandla Angalingani Kamagnetic Okwenza I-Miniaturization Ibe Yincane
Ngemikhiqizo yamandla kazibuthe (i-BHmax) edlulaAma-MGO angu-50, omaginethi be-neodymium bavumela imiklamo emincane kakhulu. Isibonelo, amarobhothi okuhlinza asebenzisa omaginethi abanosayizi wamamilimitha ukushayela amalunga amancane, enciphisa ubukhulu bedivayisi ngenkathi egcina ukunemba (isb., ukunemba okungaphansi kuka-0.1mm).

B. Ukumelana Nokugqwala kanye Nokuhambisana Nezinto Eziphilayo
Izindawo zezokwelapha zidinga ukuqina ekubulaweni inzalo, amakhemikhali, kanye noketshezi lomzimba. Ama-magnet e-Neodymium ambozwe ngei-nickel, i-epoxy, noma i-Paryleneukumelana nokuwohloka futhi kuhlangatshezwane nezindinganiso ze-ISO 10993 zokuhambisana kwezinto eziphilayo, okwenza zibe zilungele izimila.

C. Izixazululo Ezilungiselelwe Izidingo Eziyinkimbinkimbi
Kusukela ezimweni ezenziwe ngokwezifiso (amadiski, amasongo, ama-arcs) kuya kumagnetization enama-pole amaningi, amasu okukhiqiza athuthukile afanaUkusika nge-laser ye-3Dvumela ukwenza ngokwezifiso okunembile. Isibonelo, insimu yamagnetic ye-gradient ohlelweni lokuzulazula lwe-endoscopic yenziwe ngcono kusetshenziswa i-magnetization yama-pole amaningi, okuthuthukisa ukunemba kokukhomba.

3. Ukusetshenziswa Okusezingeni Eliphezulu Kwama-Neodymium Magnets Kubuchwepheshe Bezokwelapha

Isicelo 1: Izinhlelo ze-MRI—Izithombe Ezinamandla Ezinesisombululo Esiphezulu

• Ama-magnet e-Neodymium akhiqizwaamasimu kazibuthe azinzile (1.5T–3T)yemishini ye-MRI yokuqhuba i-superconducting.
• Ucwaningo Lwesibonelo: Umkhiqizi wandise isivinini sokuskena se-MRI ngo-20% esebenzisa omaginethi bendandatho bebanga le-N52 abahlanganiswe namakhoyili kagesi.

Isicelo 2: Amarobhothi Okuhlinzwa—Ukunemba Kokuhamba

• Ama-actuator amagnetic athatha indawo yamagiya amakhulu, okwenza izingalo zerobhothi zibe bushelelezi futhi zithule.
• Isibonelo: Uhlelo Lokuhlinzwa lwe-da Vinci lusebenzisa omaginethi be-neodymium ukulawula i-endoscope ngendlela enembile.

Isicelo 3: Izinhlelo Zokulethwa Kwemithi Engatshalwa

• Omaginethi amancane anika amandla amaphampu amancane angahlelwa ukuze kukhishwe umuthi ngesikhathi.
• Isidingo Esibalulekile: Ukufakwa kwe-Titanium kuqinisekisa ukuhambisana kwezinto eziphilayo.

4. Izinto Ezibalulekile Okufanele Uzicabangele Ngomklamo Wama-Neodymium Magnets Ezinga Lezokwelapha

Isinyathelo 1: Ukukhetha Izinto Nokumboza

• Ukuqina Kwezinga Lokushisa: Khetha amazinga okushisa aphezulu (isb., i-N42SH) kumadivayisi abekwe ekushiseni.
• Ukuhambisana Kokubulala Inzalo: Izembozo ze-Epoxy zimelana ne-autoclaving, kuyilapho i-Parylene ifanela imisebe ye-gamma.

Isinyathelo 2: Ukuthobela Imithetho

• Qinisekisa ukuthi abahlinzeki bayahlanganaI-ISO 13485 (Amadivayisi Ezokwelapha i-QMS)kanye nezindinganiso ze-FDA 21 CFR Part 820.
• Amadivayisi afakelwa adinga ukuhlolwa kokuhambisana kwezinto eziphilayo (ISO 10993-5 cytotoxicity).

Isinyathelo 3: Ukuthuthukisa Insimu Yama-Magnetic

• Sebenzisa i-Finite Element Analysis (FEA) ukuze ulingise ukusatshalaliswa kwensimu futhi unciphise ukuphazamiseka kwe-electromagnetic.
