style="text-indent:25px">磁鐵的歷史：隨著社會的發(fā)展，磁鐵的應(yīng)用也越來越普遍，從高科技產(chǎn)品到較簡單的包裝盒，目前應(yīng)用較為普遍的還是釹鐵硼磁鐵和鐵氧體磁鐵。從磁鐵的發(fā)展歷史來看，十九世紀(jì)末二十世紀(jì)初，人們主要使用碳鋼、鎢鋼、鉻鋼和鈷鋼作永磁材料。二十世紀(jì)三十年代末，鋁鎳鈷磁鐵開發(fā)成功，才使磁鐵的大規(guī)模應(yīng)用成為可能。五十年代，鋇鐵氧體磁鐵的出現(xiàn)，既降低了永磁體成本，又將永磁材料的應(yīng)用范圍拓寬到高頻領(lǐng)域。到六十年代，釤鈷永磁的出現(xiàn)，則為磁鐵的應(yīng)用開辟了一個新時代。1967年，美國Dayton大學(xué)的Strnat等，研制成功釤鈷磁鐵，標(biāo)志著稀土磁鐵時代的到來。稀土永磁已經(jīng)歷一代SmCo5，第二代沉淀硬化型Sm2Co17，發(fā)展到第三代Nd-Fe-B永磁材料。目前鐵氧體磁鐵仍然是用量較大的永磁材料，但釹鐵硼磁鐵的產(chǎn)值已較大超過鐵氧體永磁材料，釹鐵硼磁鐵的生產(chǎn)已發(fā)展成一大產(chǎn)業(yè)。2008年燒結(jié)釹鐵硼產(chǎn)量已經(jīng)超過6萬噸。</p><p style="text-indent:25px">釹鐵硼強力磁鐵合格的電鍍產(chǎn)品，在正常情況下，磁鐵電鍍鍍層表面不應(yīng)出現(xiàn)銹斑。釹鐵硼強力磁鐵應(yīng)該避免以下保管方式。一般正常情況下，電鍍磁鐵鍍層不易出現(xiàn)銹斑，出現(xiàn)銹斑的原因一般會有以下幾種情況：釹鐵硼強力磁鐵出現(xiàn)銹跡：1.磁鐵寄放于潮濕、氛圍流暢流暢性不好、溫差厘革之處；2.磁鐵在電鍍前輪廓的污垢沒有很好的清洗；3.電鍍的時辰不敷也許工藝流程標(biāo)題標(biāo)題；4.磁鐵的包裝封口破損釀成的磁鐵氧化；在過于潮濕、空氣流通性不好的地方；溫差變化較大時，即使是鹽霧試驗合格的產(chǎn)品長期存放于惡劣的環(huán)境下都可能產(chǎn)生銹斑。當(dāng)電鍍產(chǎn)品存放在環(huán)境惡劣的環(huán)境下，基底層進一步與凝結(jié)水反應(yīng)，會造成基底層與鍍層的結(jié)合力降低，嚴(yán)重時還會造成基底局部粉化，進而自然起皮。電鍍產(chǎn)品不應(yīng)長期放置在高濕度地方，應(yīng)當(dāng)放置在陰涼、干燥的地方。氫鍵角從105度減小到103度閣下，使水的物理化學(xué)性質(zhì)發(fā)生了發(fā)火系列改動，水的活性和消融度大猛進步。</p><div

style="text-indent:25px">釹鐵硼磁鐵特性：釹鐵硼永磁材料是以金屬間化合物Nd2Fe14B為基礎(chǔ)的永磁材料。釹鐵硼具有極高的磁能積和矯頑力，同時高能量密度的優(yōu)點使釹鐵硼永磁材料在現(xiàn)代工業(yè)和電子技術(shù)中獲得了普遍應(yīng)用，從而使儀器儀表、電聲電機、磁選磁化等設(shè)備的小型化、輕量化、薄型化成為可能。材質(zhì)特點：釹鐵硼的優(yōu)點是性價比高，具良好的機械加工特性；不足之處在于居里溫度點低，溫度特性差，且易于粉化腐蝕，必須通過調(diào)整其化學(xué)成分和采取表面處理方法使之得以改進，才能達到實際應(yīng)用的要求。制造工藝：釹鐵硼的制造采用粉末冶金工藝。工藝流程：配料→熔煉制錠→制粉→壓型→燒結(jié)回火→磁性檢測→磨加工→銷切加工→電鍍→充磁→成品。釹鐵硼磁鐵主要形狀：圓形、圓環(huán)形、方形、扁形、瓦形、梯形等。鐵氧體磁鐵特性：具有較高的磁性能，較好的時間穩(wěn)定性和較低的溫度系數(shù)。鐵氧體磁鐵應(yīng)用場所：普遍應(yīng)用于電表、儀表、電機、自動控制、微波器件、雷達和醫(yī)療器械等。鐵氧體磁鐵充磁方向：可軸向、徑向或按要求充磁。鐵氧體磁鐵主要形狀：圓形、圓環(huán)形、方形、扁形、瓦形等。不要將磁鐵接近軟盤、硬盤驅(qū)動器、卡、磁帶、徣記卡、電視顯像管等。電子化產(chǎn)品磁鐵廠家推薦</p><p
