<p><font size="3"><strong>磁铁的种类</strong></font></p>
<p><strong><font size="3">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </font></strong>&nbsp;<font size="3">磁铁的种类很多。一般分为永磁和软磁两大类。我们所说的磁铁，一般都是指永磁磁铁。 <br /></font><font size="3"></font></p>
<p><font size="3">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 永磁磁铁又分二大分类：<br /></font>
<div class="spctrl"></div>
<p><font size="3">　　</font><font size="3">第一大类：金属合金磁铁包括钕铁硼磁铁（Nd2Fe14B）、钐钴磁铁(SmCo)、铝镍钴磁铁（ALNiCO） <br /></font></p>
<div class="spctrl"></div>
<p><font size="3">　　</font><font size="3">第二大类：铁氧体永磁材料（Ferrite）<br /></font></p>
<div class="spctrl"></div>
<p><font size="3">　　</font><font size="3">1、钕铁硼磁铁： 它是目前发现商品化性能最高的磁铁，被人们称为磁王，拥有极高的磁性能其最大磁</font><font size="3">能积(BHmax)高过铁氧体(Ferrite)10倍以上。其本身的机械加工性能亦相当之好。工作温度最高可</font><font size="3">达200摄氏度。而且其质地坚硬，性能稳定，有很好的性价比，故其应用极其广泛。但因为其化学活</font><font size="3">性很强，所以必须对其表面凃层处理。(如镀Zn,Ni,电泳、钝化等)。<br /></font></p>
<div class="spctrl"></div>
<p><font size="3">　　</font><font size="3">2. 铁氧体磁铁：它主要原料包括BaFe12O19和SrFe12O19。通过陶瓷工艺法制造而成，质地比较硬，属</font><font size="3">脆性材料，由于铁氧体磁铁有很好的耐温性、价格低廉、性能适中，已成为应用最为广泛的永磁体。 <br /></font></p>
<div class="spctrl"></div>
<p><font size="3">　　</font><font size="3">3. 铝镍钴磁铁：是由铝、镍、钴、铁和其它微量金属元素构成的一种合金。铸造工艺可以加工生产成</font><font size="3">不同的尺寸和形状，可加工性很好。铸造铝镍钴永磁有着最低可逆温度系数，工作温度可高达600摄</font><font size="3">氏度以上。铝镍钴永磁产品广泛应用于各种仪器仪表和其他应用领域。 <br /></font></p>
<div class="spctrl"></div>
<p><font size="3">　　</font><font size="3">4、钐钴（SmCo）依据成份的不同分为SmCo5和Sm2Co17。由于其材料价格昂贵而使其发展受到限制。钐</font><font size="3">钴（SmCo）作为稀土永磁铁，不但有着较高的磁能积（14-28MGOe）、可靠的矫顽力和良好的温度特</font><font size="3">性。与钕铁硼磁铁相比，钐钴磁铁更适合工作在高温环境中。 </font></p>
<h2 class=""><a name="9"></a><font size="3"></font></h2>
<h2 class=""><font size="3">磁铁的历史</font></h2>
<p><font size="3">　　</font><font size="3">随着社会的发展，磁铁的应用也越来越广泛，从高科技产品到最简单的包装磁，目前应用最为广泛的</font><font size="3">还是钕铁硼磁铁和铁氧体磁铁。 从磁铁的发展历史来看，十九世纪末二十世纪初，人们主要使用碳</font><font size="3">钢、钨钢、铬钢和钴钢作永磁材料。二十世纪三十年代末，铝镍钴磁铁开发成功，才使磁铁的大规模应</font><font size="3">用成为可能。五十年代，钡铁氧体磁铁的出现，既降低了永磁体成本，又将永磁材料的应用范围拓宽到</font><font size="3">高频领域。到六十年代，钐钴永磁的出现，则为磁铁的应用开辟了一个新时代。1967年，美国Dayton</font><font size="3">大学的Strnat等，研制成钐钴磁铁，标志着稀土磁铁时代的到来。迄今为止，稀十永磁已经历第一代</font><font size="3">SmCo5，第二代沉淀硬化型Sm2Co17，发展到第三代Nd-Fe-B永磁材料。目前铁氧体磁铁仍然是用量最大</font><font size="3">的永磁材料，但钕铁硼磁铁的产值已大大超过铁氧体永磁材料，钕铁硼磁铁的生产已发展成一大产业。 <br /></font></p>
<div class="spctrl"></div>
<p><font size="3">　　</font><font size="3"><strong>磁力大小排列为</strong>：钕铁硼磁铁、钐钴磁铁、铝镍钴磁铁、铁氧体磁铁。<br /></font></p>
<div class="spctrl"></div>
<p><font size="3">　　</font><font size="3"><strong>磁铁制作工艺：</strong> 钕铁硼磁铁、钐钴磁铁、铝镍钴磁铁、铁氧体磁铁制作工艺也有所不同。从工艺讲，有烧结钕铁硼磁铁和粘接钕铁硼磁铁，我们主要讲烧结钕铁硼磁铁。</font></p>

<![CDATA[<font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 磁铁，应该叫磁钢，英文 Magnet，磁钢现在主要分两大类，一类是软磁，一类是硬磁；<br /></font>
<div class="spctrl"></div>
<font size="4">　　软磁包括硅钢片和软磁铁芯；硬磁包括铝镍钴、钐钴、铁氧体和钕铁硼，这其中，最贵的是钐钴磁钢，最便宜的是铁氧体磁钢，性能最高的是钕铁硼磁钢，但是性能最稳定，温度系数最好的是铝镍钴磁钢，用户可以根据不同的需求选择不同的硬磁产品。<br /></font>
<div class="spctrl"></div>
<font size="4">　　怎样来定义磁铁的性能？<br /></font>
<div class="spctrl"></div>
<font size="4">　　主要有如下3个性能参数来确定磁铁的性能：<br /></font>
<div class="spctrl"></div>
<font size="4">　　剩磁Br :永磁体经磁化至技术饱和，并去掉外磁场后，所保留的Br称为剩余磁感应强度。<br /></font>
<div class="spctrl"></div>
<font size="4">　　矫顽力Hc:使磁化至技术饱和的永磁体的B降低到零，所需要加的反向磁场强度称为磁感矫顽力，简</font><font size="4">称为矫顽力<br /></font>
<div class="spctrl"></div>
<font size="4">　　磁能积BH:代表了磁铁在气隙空间（磁铁两磁极空间）所建立的磁能量密度，即气隙单位体积的静磁能量。由于这项能量等于磁铁的Bm和Hm的乘积，因此称为磁能积。<br /></font>
<div class="spctrl"></div>
<font size="4">　　磁场:对磁极产生磁作用的空间为磁场<br /></font>
<div class="spctrl"></div>
<font size="4">　　表面磁场:永磁体表面某一指定位置的磁感应强度<br /></font>
<div class="spctrl"></div>
<font size="4">　　如何选择磁铁？<br /></font>
<div class="spctrl"></div>
<font size="4">　　在决定选择哪一种磁铁之前应明确需要磁铁发挥何种作用？<br /></font>
<div class="spctrl"></div>
<font size="4">　　主要的作用：移动物体，固定物体或抬升物体。<br /></font>
<div class="spctrl"></div>
<font size="4">　　所需磁铁的形状：圆片形，圆环形，方块形，瓦片形或特殊形状。<br /></font>
<div class="spctrl"></div>
<font size="4">　　所需磁铁的尺寸：长，宽，高，直径及公差等等。<br /></font>
<div class="spctrl"></div>
<font size="4">　　所需磁铁的吸力，期望价格及数量等等。<br /></font>
<div class="spctrl"></div>
<font size="4">　　指南针就是根据磁铁的性质发明的</font>]]>

<![CDATA[&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <font size="4">有些时候,一提肯德基,我真的控制不住自己的情绪.在这里,我只是以一种十分客观的态度把肯德基的一些内幕告诉大家,只希望每个中国人...能真正认识肯得基.我慢慢说我的经历吧. 本人是个在外漂泊的大学生,说来惭愧,在外也认识了不少朋友.我的一个朋友的父亲是中国银行某市的一个高层领导,他和美国的肯德基之间有些合作的关系,一次高层领导之间的互访使我朋友的父亲有幸参观了肯德基的鸡厂,那是个对外严重保密的地方,任何人都不能随便入内的.那天我和朋友也正在上自习,朋友突然接到他父亲的电话,是从美国打来的越洋电话,&quot;以后绝对不允许再吃肯德基了.'他父亲说完就挂了.一星期之后,他父亲从美国回来后专门来了一趟我们学校,我和他们父子在一起聊天,也有幸听到了肯德基鸡厂的内幕.</font>
<p><br /><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 每个鸡身上全插着管子,一只鸡从孵出来到成品鸡的时间是两个星期。管子给他们输的是激素啊!每个鸡身上根本没有毛,就象我们见到的已经开膛破肚拔完毛之后的鸡一个样!朋友们,你们知道我们在肯德基里面吃的是鸡的腿和翅是最多的,几乎全是腿和翅,你们想想,哪里来那么多的腿和翅,其它的部位都哪去了呢?差不多每只鸡身上有4-5个翅膀,3-4个腿。我真的都已经出离愤怒了.看着城市里那一块块肯德基的牌子, 我......无语了!朋友可以到肯德基里面去观察一下，在里面吃的都是什么人，你一定不会看到外国人的，全是中国人啊。尤其多的是中国的小孩子，这些年一直受到激素困扰正常发育的中国未成年人。外国人自己发明的东西自己却不喜欢吃，聪明的中国人啊，大家都想一想这是为什么呢？？？据说，不管肯德基还是麦当劳或者其他西方快餐连锁企业，为了在中国市场开创&ldquo;大好&rdquo;局面，都有专门研究特别适合中国人口味，让中国人喜欢的口味配方，以此作为企业开发重点。另外就是研究开发一只鸡身上能长出多条鸡腿和多只翅膀的激素催生技术。</font></p>
<p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 现在已经能催生到6条鸡腿6只翅膀了，但是由于是针对中国消费者&mdash;&mdash;世界上最盲目无知的消费者，所以只是粗放式激素配方喂养，所以往往有一只鸡身上长有3条腿3只翅膀，或者4只，5只，6只等等不一而足。过去把鸡翅膀和鸡腿切割下来运输到中国市场，其他身体部位还原成饲料。现在又有企业为了减少成本和产生更好的经济效益，把这种鸡身体的绝大部分加工成鸡肉柳，也一并运输到中国市场倾销，因此而产生极大的经济利润。外国人在获取极大利润的同时，我们国人的身体健康和子孙后代的身体健康却受到极大的伤害！为什么现在的小孩子都比较肥胖呢，就是吃了这些含有大量激素的洋垃圾食品啊!不管是爱国的国人，还是爱国意识淡漠的国人，总肯定是会为自己的孩子的身体健康要考虑的吧！拒绝洋快餐！！！</font></p>
