I-Magnets ifike ibanga elide kusukela ezinsukwini zobusha bakho lapho uchitha amahora amaningi uhlela lezo zindawo zophahla zepulasitiki ezinemibala ekhanyayo emnyango. Ama-magnets anamuhla anamandla kunangaphambili futhi okuhlukahlukene kuyabenza balusizo ezinhlobonhlobo zezicelo.
Umhlaba ongavamile no-Ceramic Magnets - ikakhulukazi indawo enkulu yomhlaba engavamile - uguqule izimboni eziningi namabhizinisi ngokwandisa inani lezicelo noma ukwenza izinhlelo zokusebenza ezikhona zisebenze kahle. Ngenkathi abaningi bebhizinisi banikazi beqaphela la ma-marthets, ukuqonda okubenza bahluke kungadida. Nansi i-rundown esheshayo yomehluko phakathi kwezinhlobo ezimbili zama-magnets, kanye ne-synopsis yezinzuzo zazo ezihlobene nokubi:
Umhlaba ongavamile
Lawa ma-Magnets anamandla amakhulu angakhiwa nge-neodymium noma i-sambarium, zombili ezingowochungechunge lwezinto zeLanthanide. ISamarium yaqala ukusetshenziswa ngawo-1970, ngama-neodymium magnets asetshenziswa ngawo-1980s. Kokubili i-neodymium ne-sambariyu kunama-magrets omhlaba aqinile futhi asetshenziswa ezinhlelweni eziningi zezimboni kufaka phakathi ama-turbines anamandla kakhulu kanye nama-generator kanye nezinhlelo zokusebenza zesayensi.
Needymium
Kwesinye isikhathi ibizwa ngokuthi ama-ndfeb magnets wezinto eziqukethe - i-neodymium, i-iron kanye ne-boron, noma i-nib - i-neodymium magnets yizimpawu ezinamandla kakhulu ezikhona. Umkhiqizo we-Energy omkhulu (BHMAX) walawa ma-magnets, amele amandla asemqoka, angaba ngaphezu kwe-50mgoe.
Leyo bhmax ephezulu - cishe izikhathi eziyi-10 ephakeme kune-ceramic magnet - iyenza ilungele ezinye izinhlelo zokusebenza, kepha kukhona ukuhwebelana: i-neodymium inokumelana okuphansi kokucindezelwa okushisayo, okusho ukuthi uma kudlula amandla alo okusebenza. I-TMAX yeNeodymium Magnets ingama-degrees angama-150, cishe isigamu se-cobarlt noma i-ceramic. (Qaphela ukuthi izinga lokushisa eliqondile lapho ama-marthets alahlekelwa amandla awo lapho kuvezwa ukushisa kungahlukahluka ngokusekelwe ku-alloy.)
Ama-Magnets nawo angaqhathaniswa ngokususelwa ku-tcurie yawo. Lapho ama-magnets efudunyezwa emazingeni okushisa adlula i-tmax yawo, ezimweni eziningi angalulama futhi apholile; I-Tcurie izinga lokushisa elingaphezu kwalo lonke lolukutholile. Okwe-Needmium Magnet, i-Tcurie ingama-310 degrees Celsius; Ama-Neodymium Magnets afudumele noma ngaphezu kwalelo lokushisa ngeke akwazi ukubuyisa ukusebenza lapho kupholile. Kokubili ama-Samarium nama-ceramic magnets anezinto eziphakeme, ezibenza babe ukukhetha okungcono kwezicelo eziphakeme kakhulu.
Ama-neodymium Magnets amelana kakhulu nokuba sehlukaniswe ngamasimu kazibuthe angaphandle, kepha athambekele ekugqwabeni futhi iningi lama-magnets lihlanganiswe ukuhlinzeka ngokuvikela ekugcekeni.
I-Samarium Cobalt
I-Samarium Cobalt, noma i-SACO, omazibuthe batholakala ngawo-1970s, futhi kusukela ngaleso sikhathi, basetshenziswe ezinhlelweni ezahlukahlukene zezicelo. Yize eqinile njenge-Needmium Magnet - I-Samarium Cobalt Magnets evame ukuba ne-BHMAX yango-26 cishe angu-26 - Lezi zibuthe zinenzuzo yokukwazi ukubekezelela amazinga okushisa aphezulu we-neodymium. I-TMAX ye-SAMARIUM COBALT WAGENT ingama-300 degrees Celsius, kanti i-Tcurie ingaba ngama-degrees angama-750. Amandla abo ahlobene ahlanganiswe nekhono labo lokumelana namazinga okushisa aphezulu abenze abe elungele izinhlelo eziphakeme zokushisa. Ngokungafani ne-Neodymium Magnets, ama-Samarium Cobalt Magnets anokumelana kahle nokugqwala; Futhi bavame ukuba nephuzu lentengo eliphakeme kunama-neodymium magnets.
-Ezitsha zobumba
Kwenziwe nge-barium Ferrite noma i-strontium, ama-cerantic magnets abehamba isikhathi eside kunomhlaba onqabile futhi asetshenziswa okokuqala ngawo-1960. I-Ceramic Magnets ngokuvamile ayibiza kakhulu kunemibala yomhlaba ongavamile kepha ayinamandla nge-bhmax ejwayelekile engaba ngu-3.5 - cishe weshumi noma ngaphansi kwe-neodymium noma ngaphansi kwe-comodmium noma ngaphansi kwaleyo
Mayelana nokushisa, ama-ceramic magnets ane-tmax yama-degree angama-300 e-Celsius futhi, njengama-sogarium magnets, i-tcurie yama-degrees angama-460 celsius. Ama-Curamic Magnets amelana kakhulu nokugqwala futhi ngokuvamile awadingi ukuhlanganiswa okuvikelayo. Kulula ukukletha futhi futhi akubizi kakhulu kuneNedmium noma iSamarium Cobalt Magnets; Kodwa-ke, ama-ceramic magnets ane-brittle kakhulu, abenze ukuthi kube ukukhetha okungekuhle kwezicelo ezibandakanya ukuguquguquka okukhulu noma ukucindezela. Ama-peramic magnets ajwayele ukusetshenziselwa ukuklolonga kwasekilasini kanye nezinhlelo ezingaphansi zezimboni nezinhlelo zokusebenza zebhizinisi, ezifana nabakhiqizi bebanga eliphansi noma ama-turbines. Zingase futhi zisetshenziswe ezinhlelweni zasekhaya nasekukhiqizweni kwamashidi kazibuthe kanye nezimpawu.
