line-height: 1.75em;&quot;&gt;氧化铝陶瓷具有多种优势，它的机械强度高、硬度大、高频介电损耗小，又因为它的原料来源广、价格相对便宜、加工技术较为成熟，因此，它被广泛地应用于电子、电器、机械、纺织和航空航天等领域。这也奠定了它在陶瓷材料领域的高地位。据悉，氧化铝陶瓷是目前世界上用量最大的氧化物陶瓷材料。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;氧化铝陶瓷是一种以Al2O3为主要原料，以刚玉(α—Al2O3)为主晶相的陶瓷材料。由于氧化铝熔点高达2050℃，导致氧化铝陶瓷的烧结温度普遍较高(参见表一中标准烧结温度)，从而使得氧化铝陶瓷的制造需要使用高温发热体或高质量的燃料以及高级耐火材料作窑炉和窑具，这在一定程度上限制了它的生产和更广泛的应用。因此，降低氧化铝陶瓷的烧结温度，降低能耗，缩短烧成周期，减少窑炉和窑具损耗，从而降低生产成本，一直是企业所关心和急需解决的重要课题。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);

line-height: 1.75em;&quot;&gt; &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;一、通过提高Al2O3粉体的细度与活性降低瓷体烧结温度&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;　　&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;Al2O3粉体的颗粒越细，活化程度越高，粉体就越容易烧结，烧结温度越低。在氧化铝瓷低温烧结技术中，使用高活性易烧结Al2O3粉体作原料是重要的手段之一，因而粉体制备技术成为陶瓷低温烧结技术中一个基础环节。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt; &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;二、通过瓷料配方设计掺杂降低瓷体烧结温度&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt; &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;氧化铝陶瓷的烧结温度主要由其化学组成中Al2O3的含量来决定，Al2O3含量越高，瓷料的烧结温度越高，除此之外，还与瓷料组成系统、各组成配比以及添加物种类有关。比如，在Al2O3含量相当时，CaO-Al2O3-SiO2系Al2O3瓷料比MgO-Al2O3-SiO2系瓷料的烧结温度低，对于我国目前大量生产CaO-MgO-Al2O3-SiO2系统瓷料而言，为使其具有较低的烧结温度与良好性能，应控制其SiO2／CaO处于1.6～0.6之内，MgO含量不超过熔剂类氧化物总量的1／3，同时，在配方中引入少量的La2O3、Y2O3、Cr2O3、MnO、TiO2、ZrO2、Ta2O3等氧化物能进一步降低烧结温度、改善瓷体的微观组织结构和性能。因此，在保证瓷体满足产品使用目的和技术要求的前提下，我们可以通过配方设计，选择合理的瓷料系统，加入适当的助烧添加剂，使氧化铝陶瓷的烧结温度尽可能降低。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;目前配方设计中所加入的各种添加剂，根据其促进氧化铝陶瓷烧结的作用机理不同，可以将它们分为形成新相或固溶体的添加剂和生成液相的添加剂二大类。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt; &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;三、采用特殊烧成工艺降低瓷体烧结温度&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt; &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;采用热压烧结工艺，在对坯体加热的同时进行加压，那么烧结不仅是通过扩散传质来完成，此时塑性流动起了重要作用，坯体的烧结温度将比常压烧结低很多，因此热压烧结是降低Al2O3陶瓷烧结温度的重要技术之一。目前热压烧结法中有压力烧结法和高温等静压烧结法(HIP)二种。HIP法可使坯体受到各向同性的压力，陶瓷的显微结构比压力烧结法更加均匀。就氧化铝瓷而言，如果常压下普通烧结必须烧至1800℃以上的高温，热压20MPa烧结，在1000℃左右的较低温度下就已致密化了。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt; &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;热压烧结技术不仅显著降低氧化铝瓷的烧结温度，而且能较好地抑制晶粒长大，能够获得致密的微晶高强的氧化铝陶瓷，特别适合透明氧化铝陶瓷和微晶刚玉瓷的烧结。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt; &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;此外，由于氧化铝的烧结过程与阴离子的扩散速率有关，而还原气氛有利于阴离子空位的增加，可促进烧结的进行。因此，真空烧结、氢气氛烧结等是实现氧化铝瓷低温烧结的有效辅助手段。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt; &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;在生产实践中，为获得最佳综合经济效益，上述低烧技术往往相互配合使用，其中加入助烧添加剂的方法相对其它方法而言，具有成本低、效果好、工艺简便实用的特点。在中铝瓷、高铝瓷和刚玉瓷的生产中被广泛使用。另外，从材料角度来看，通过掺杂改性技术，大幅度提高氧化铝陶瓷的各项机电性能，用Al2O3含量低的瓷体代替Al2O3含量高的瓷体，也是企业常用的降低氧化铝陶瓷产品烧结温度的有效技术手段。比如在材料性能满足产品使用要求下，用85瓷代替90瓷或95瓷，用90瓷、95瓷代替99瓷等都是可行的。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt; &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;虽然目前氧化铝陶瓷低烧技术已经取得了比较好的经济效益，但是，现在有些产品仍然有很大的升值空间可以挖掘。从材料的特殊性能要求上考虑，如果仍然采用高温烧结的技术，那么如何将这类产品的烧结温度降下来将会是今后瓷体掺杂改性等低烧技术的努力方向。&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;</description><pubDate>Fri, 23 Oct 2026 13:21:35 +0800</pubDate></item><item><title>影响布袋除尘器除尘效果的因素及预防措施</title><link>http://jm-powder.com/post/1741.html</link><description>&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;1.除尘布袋的质量及选型&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;作为布袋除尘器最为关键性的配件，布袋性能与质量的好坏在很大程度上决定着布袋除尘器的工作效率以及使用寿命的长短，通常来说，布袋质量越好，除尘的工作效率越高、使用寿命越长。而布袋的选型同样制约着除尘效果的好坏，如出现“以大带小”的状况，即会出现龙骨(支撑布袋的结构件通常称为龙骨)与布袋结合不严，烟尘会通过缝隙漏出，最后自烟囱冒出，并产生一系列不良反应;如出现“以小带大”虽然也可以使用，但在吸附比重较大的粉尘后，使用一段时间便会出现掉袋现象，烟囱经常出现冒黑烟状况。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;2.反吹系统的问题&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;布袋除尘器的反吹系统是整个除尘器长期运行的保障。当前应用较为普遍和广泛的反吹系统多为脉冲式反吹，此种清灰方式主要是根据反吹空气压力原理来进行的，具有十分良好的清灰效果和较高的自动化程度。而脉冲式反吹法同样存在较多的缺点。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;⑴反吹过程产生较大振动，导致反吹管频繁出现掉落及仓室进出、口翻版松动关闭等情况，除尘系统压差随之不断上升除尘效果随之下降。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;⑵脉冲式反吹法需要有持续的压缩空气来支撑脉冲喷吹工作，一旦压缩空气突然停止，除尘器系统压差将会出现较大幅度的涨幅，如不及时恢复，将对除尘布袋产生严重破坏。另外，如压缩空气中含水量较大，长期运行，一是会使布袋潮湿，细小的焦粉与布袋粘结导致布袋透风率急剧下降，除尘系统压差也随之逐渐升高，将会严重降低除尘效果的同时，加剧布袋的损坏速度。二是电磁阀进水无法正常工作，它所控制的脉冲阀、离线阀也无法动作，使得反吹效果大幅度降低，除尘效果也随之降低，此现象冬季最为明显。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;⑶脉冲式反吹法的反吹程序(即相关反吹命令的间隔时间)必须通过生产节奏及产灰量的大小进行调整，否则无法发挥出布袋除尘的最佳效果。比如脉冲阀开闭时间一般设定为0.2～0.3s为最佳，少则脉冲阀无动作，多则浪费压缩风资源，且反吹效果不佳。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;3.除尘器本体和除尘点的密封情况&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;除尘器本体和除尘点的密封情况直接影响除尘效果。布袋除尘一般都是负压运行，如漏风易形成小回路短路，除尘系统的风量造成浪费而导致正压扬尘。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;4.其他因素&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;刨除原设计缺陷、机械故障外，由于管理及操作不善导致的除尘管道内部积灰、灰仓蓬料、冷却仓堵塞等，均会造成除尘器整体阻力不断上升，近而影响除尘效果。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;预防措施&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;&lt;span style=&quot;box-sizing: border-box; font-weight: 700;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;⑴对现有布袋除尘器的布袋和龙骨规格进行详细核实备案，根据各除尘器的生产工艺条件充分研究相关布袋的技术资料，并考虑其运行周期及运行成本，按综合指标进行技术经济比较，从而确定布袋的材质和规格。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;⑵针对脉冲式反吹系统提出如下建议:&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;①对各除尘反吹管道和仓室翻版的固定方式进行有效改造，比如螺丝固定处增设弹簧垫、双螺帽等方式，以进一步控制反吹管频繁出现掉落及仓室进出、口翻版松动关闭等情况;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;②每套除尘器配备两套供风管路，确保在一路停止的情况下能够及时倒用，且严格控制压缩空气含水情况;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;③通过对产灰量及除尘效果的分析对比，适当调整反吹频次和过风量。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;⑶加强除尘器本体和除尘点的密封。除尘系统主要有除尘器本体和除尘系统的其他设备，如检查人孔、除尘管道、卸料设备双层阀或刚性叶轮格式阀、输送设备刮板机、仓顶盖板等。其中需要加强密封的主要包括壳体的焊口、仓顶盖板、检查人孔、刮板机盖板等。其中盖板、检查人孔以及设备连接处可以用黄油或耐热玻璃胶进行二次密封。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;⑷进一步提高环保意识，除尘系统不是生产系统的辅助，它是生产工艺系统中一个主要设备，它运行的好坏直接影响生产环境和操作人员的身心健康，所以要保证生产设备和除尘系统的同步率和完好率。另外，需加强除尘系统的管理维护力度，制定切实可行的操作规程和维护规程，充分利用好系统停机检修契机做好关键除尘系统设备设施的检修维护。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);&quot;&gt;&lt;span style=&quot;box-sizing: border-box; line-height: 1.75em;&quot;&gt;综上所述，影响布袋除尘器除尘效果的因素较多，但只要我们充分了解和掌握除尘器的技术性能和工艺原理，并能善于发现问题，制定科学有效的管理和维护手段，就能最大限度地提高除尘效率，并发挥除尘器应有的作用。&lt;/span&gt;&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;</description><pubDate>Thu, 22 Oct 2026 16:58:38 +0800</pubDate></item><item><title>硅微粉和石英的区别</title><link>http://jm-powder.com/post/1740.html</link><description>&lt;div style=&quot;font-variant-num d-image: none;
