Fomba tsy fahita firy eto an-tany

Samarium Cobalt Magnet Topimaso sy andinindray:

Samarium Cobalt (SmCo) dia antsoina koa hoe andriamby Cobalt tsy fahita eto an-tany. Ny fanoherana avo lenta ny demagnetisation ary ny fitoniana eo amin'ny mari-pana dia mahatonga ny SmCo magnet avo na hafanana Sm2Co17 hiasa mafy eo ambanin'ny maripana avo hatramin'ny 350 ° C. Matetika tsy ilaina ny sarona. Noho izany SmCo magnet dia safidy tsara indrindra amin'ny fitaovana magnet ho an'ny fampiharana avo lenta toy ny aerospace, motorsports ary ny indostrian'ny fiara.

Andriamby fiarovana:

Ny magnetika eto an-tany tsy fahita firy na ny rafitra magnetika dia mahery tokoa, noho izany ny fitandremana ny fiarovana eto ambany dia tsy maintsy entina amin'ny sain'ny mpiasa rehetra izay mety hampiasa, hitantana na hanodina azy ireo mba hialana amin'ny ratra na fahasimban'ny andriamby manokana.

Hamarino tsara fa voafehy ny andriamby andriamby tsy dia manara-penitra rehefa mifampikasoka na fitaovana ferromagnetika izy ireo. Zava-dehibe ny mitafy solomaso fiarovana ary fitaovam-piarovana mety hafa rehefa mikarakara andriamby lehibe. Ny fanaovana fonon-tànana hiarovana ny tananao dia atolotra anao koa.

Arovy ny metaly ferromagnetika tsy ho eo amin'ny sehatry ny asa. Mitandrema rehefa miasa amin'ny andriamby. Aza miasa amin'ny andriamby andriamby raha toa ka iharan'ny alikaola, zava-mahadomelina, na zavatra voafehy ianao.

Ireo fitaovana sy fitaovana elektronika saro-pady dia mety hanova kalibration na ho simba amin'ny sahan'andriamby mahery. Tazomy hatrany ny andriamby andriamby ary tsy lavitra ireo fitaovana elektronika mora tohina. Tokony hotandremana manokana raha manao fitaovam-pandrefesana ny olona iray satria ny sahan'andriamby matanjaka dia mety hanimba ireo fitaovana elektronika ao anaty pacemaker.

Aza mitelina andriamby velively na mametraka andriamby ho azon'ny ankizy na olon-dehibe marary saina. Raha voatelina ny andriamby dia manatona dokotera avy hatrany ary / na manatona fitsaboana eo noho eo.

Ny andriamby tsy fahita eto an-tany dia mety hiteraka tsilo amin'ny alàlan'ny fifandraisana amin'ny fikirakirana, indrindra rehefa avela hiara-miantraika. Aza mitantana ny andriamby tsy fahita firy eto amin'ny habakabaka mipoaka satria mety hampirehitra izany atmosfera izany.

Mora may ny vovoka eto an-tany; ny doro tampoka dia mety hitranga rehefa maina ny vovo-tany. Raha mitoto volo, dia esory foana ireo andriamby mando foana mba hisorohana ny fandoroana tampoka ilay trondro tsy mitoto. Aza maina maina. Hamarino tsara fa manana rivotra madio ianao rehefa manodina andriamby. Aza manandrana manamboatra andriamby andriamby amin'ny fampiasana fitaovana mahazatra, satria io dia mety hiteraka kapoka sy vaky. Manaova vera fiarovana foana.

Tehirizo ao anaty kaontenera feno rano foana na vovo-tany tsy fahita firy ny vovo-tany na fitotoana fikosoham-bary hisorohana ny fahamaizana tampoka.

Ario am-pitandremana foana ny vovoka tsy fahita eto an-tany. Aza ahiana ho may. Ny fanariana andriamby andriamby dia tsy maintsy atao mba hisorohana ny ratra rehefa mandray.
