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，十九世紀末二十世紀初，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。完成汽車向小型化、輕量化、高功能化和節(jié)能環(huán)保偏向開展。</p><div

style="text-indent:25px">所有的磁鐵都是有正負極之分的，磁鐵的周圍是存在磁場的，當磁鐵相互靠近的時候，由于磁場的互斥作用，兩塊相同極的磁鐵要想吸在一起好像有股力量一定要讓它們分開的，當兩個不同極的面靠近一起時就會吸引。簡單來說，磁鐵的排斥是由于磁鐵中的磁場作用產(chǎn)生的。這就是我們平常所學(xué)的物理學(xué)中的異性相吸，同性相斥。能吸引鐵、鈷、鎳等物質(zhì)的性質(zhì)稱為磁性。磁鐵兩端磁性強的區(qū)域稱為磁極，一端稱為北極（N極），一端稱為南極（S極）。實驗證明，同性磁極相互排斥，異性磁極相互吸引。物質(zhì)大都是由分子組成的，分子是由原子組成的，原子又是由原子核和電子組成的。在原子內(nèi)部，電子不停地自轉(zhuǎn)，并繞原子核旋轉(zhuǎn)。電子的這兩種運動都會產(chǎn)生磁性。但是在大多數(shù)物質(zhì)中，電子運動的方向各不相同、雜亂無章，磁效應(yīng)相互抵消。因此，大多數(shù)物質(zhì)在正常情況下，并不呈現(xiàn)磁性。在這種前處理工藝過程中，如果其中一個環(huán)節(jié)處理得不干凈，會導(dǎo)致電鍍層出現(xiàn)起泡、剝落等問題。常州電子化產(chǎn)品磁鐵廠家推薦</p><p

style="text-indent:25px">釹鐵硼由那些材料組成？釹鐵硼永磁鐵的主要原材料有稀土金屬釹(Nd)32%、金屬元素鐵(Fe)64%和非金屬元素硼(B)1%(少量添加鏑(Dy)、鋱(Tb)、鈷(Co)、鈮(Nb)、鎵(Ga)、鋁(Al)、銅(Cu)等元素)。釹鐵硼三元系永磁材料是以Nd2Fe14B化合物作為基體的，其成分應(yīng)與化合物Nd2Fe14B分子式相近。但完全按Nd2Fe14B成分配比時,磁體的磁性能很低，甚至無磁。只是實際的磁體當中釹和硼的含量比Nd2Fe14B化合物的釹和硼含量多時才能獲得較好的永磁性能。釹鐵硼的磁性能可以持續(xù)多久？釹鐵硼磁鐵擁有相當高的矯頑力，自然環(huán)境和一般磁場條件下不會出現(xiàn)退磁和磁性變化。假設(shè)環(huán)境適當，即使經(jīng)過長時間的使用，磁體的磁性能損失也不會很大。所以在實際應(yīng)用中，我們往往忽略時間因素對磁性能的影響。紹興異形磁鐵廠家電話</p><p
