Samarium KobaltMagnetĦarsa ġenerali u Speċifikazzjonijiet:
Il-kalamita Samarium Cobalt (SmCo) tissejjaħ ukoll kalamita tal-Kobalt tal-art rari. Ir-reżistenza għolja tagħha għad-demagnetization u l-istabbiltà tat-temperatura eċċellenti tagħmel SmCo kalamita ta 'temperatura għolja jew kalamita Sm2Co17 biex taħdem stabbli taħt temperatura għolja sa 350 °C. Normalment l-ebda kisi ma jkun meħtieġ. Għalhekk il-kalamita SmCo hija għażla premium ta 'materjal kalamita għal ħafna applikazzjonijiet ta' prestazzjoni għolja bħall-industriji tal-ajruspazju, tal-motorsports u tal-karozzi.

Sigurtà tal-kalamita:
Kalamiti tad-dinja rari jew sistemi manjetiċi huma estremament b'saħħithom, għalhekk il-prekawzjonijiet ta 'sigurtà hawn taħt għandhom jinġiebu għall-attenzjoni tal-persunal kollu li jista' jużahom, jimmaniġġjahom jew jipproċessahom sabiex jiġi evitat korriment personali jew ħsara lill-kalamiti.
Kun żgur li magnetized kalamiti terrestri rari huma taħt kontroll meta jiġu f'kuntatt ma ' xulxin jew materjali ferromanjetiċi. Huwa importanti li tilbes nuċċalijiet tas-sigurtà u tagħmir protettiv ieħor xieraq meta timmaniġġja kalamiti kbar. Liebes ingwanti biex jipproteġi idejk huwa wkoll rakkomandat.
Żomm metalli ferromanjetiċi 'l bogħod miż-żona tax-xogħol. Oqgħod attent meta taħdem bil-kalamiti. Taħdimx b'kalamiti magnetizzati jekk tkun taħt l-influwenza ta 'alkoħol, drogi, jew sustanzi kkontrollati.
Strumenti u apparati elettroniċi sensittivi jistgħu jbiddlu l-kalibrazzjoni jew jiġu mħassra minn kamp manjetiku qawwi. Dejjem żomm il-kalamiti magnetizzati 'l bogħod minn strumenti elettroniċi sensittivi. Għandha tingħata attenzjoni speċjali jekk wieħed ikun liebes pacemaker, minħabba li kampi manjetiċi qawwija jistgħu jagħmlu ħsara lill-elettronika ġewwa pacemakers.
Qatt tibla' kalamiti jew tpoġġi kalamiti fejn jintlaħqu minn tfal jew adulti mentalment batuti. Jekk jinbelgħu kalamiti, ikkonsulta tabib immedjatament u/jew fittex attenzjoni medika immedjata.
Kalamiti tad-dinja rari jistgħu joħolqu xrar permezz ta 'kuntatt fl-immaniġġjar, speċjalment meta jitħallew jolqtu flimkien. Qatt m'għandek timmaniġġja kalamiti tad-dinja rari f'atmosferi splussivi għax l-isparking jista' jaqbad dik l-atmosfera.
Trab tal-art rari huwa kombustibbli; kombustjoni spontanja tista 'sseħħ meta t-trab ikun niexef. Jekk tħin, dejjem imxarrab kalamiti tat-tħin biex tevita l-kombustjoni spontanja tat-tħin tat-tħin. Qatt itħan niexef. Kun żgur li jkollok ventilazzjoni adegwata meta tħin il-kalamiti. Tippruvax magni kalamiti bl-użu ta 'għodod konvenzjonali, peress li dan jista' jipproduċi tixlif u tifrik. Dejjem ilbes nuċċalijiet tas-sigurtà.
Dejjem aħżen trab ta 'earth rari jew tħin f'kontenituri mimlija bl-ilma jew atmosferi inerti ssiġillati ermetikament biex tevita l-kombustjoni spontanja.
Dejjem armi trab tad-dinja rari b'attenzjoni. Tirriskjax nirien. Ir-rimi tal-kalamiti magnetizzati għandu jsir biex jipprevjeni korriment meta jiġu mmaniġġjati.
