margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;4.其他因素&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; 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: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px;&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;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box;

text-wrap-mode: wrap; background-color: #FFFFFF;'&gt;    根据工业发达国家的发展经验，在工业和社会发展到一定程度后，非金属矿及非金属矿物材料的消费和产值将超过金属矿及金属矿物。硅灰石作为一种附加值高、增长快的非金属矿物材料，随着研究的深入，研究方向应集中到对硅灰石在非陶瓷方面的开发应用，其中填料是其最具潜力的应用领域。经过深加工的硅灰石超细产品及针状粉增值到初级产品的几倍甚至几十倍。未来塑料、橡胶、涂料和造纸行业对各种填料的需求将突破2 000万t，而对硅灰石针状粉等优质填料的需求更为迫切。&lt;/span&gt;&lt;br style='box-sizing: border-box;

margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;镁及镁合金虽具有密度低、比强度大、比刚度高和抗冲击性强等诸多优点。但是也有一些固有缺点，如硬度、刚度、耐磨性、燃点较低、不是一种良好的结构材料，使其应用受到相当大的制约。若向镁基体中添加陶瓷颗粒或碳纤维制成复合材料，则可以在很大程度上改善镁的力学性能，提高耐热和抗蠕变性能，降低热膨胀系数等。可作为复合材料增强相的颗粒有：氧化物、碳化物、氮化物、陶瓷、石墨和碳纤维等。制备镁基复合材料的工艺主要是：铸造法、粉末冶金法、喷射沉积法。&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box;

margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;铸造法是制备镁合金复合材料的基本工艺，可分为搅拌混合法、压力浸渗法、无压浸渗法和真空渗法等。&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px;

margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;此法是利用高速旋转搅拌器浆叶搅动金属熔体，使其剧烈流动，形成以搅拌旋转轴为中心的漩涡，将增强颗粒加入漩涡中，依靠漩涡负压抽吸作用使颗粒进入熔体中，经过一段时间搅拌，颗粒便均匀分布于熔体内。此法简便，成本低，可以制备含有Sic、Al2O3、SiO2、云母或石墨等增强相的镁基复化材料。不过也有一些难以克服的缺点：在搅拌过程中会混入气体与夹杂物，增强相会偏析与固结，组织粗大，基体与增强相之间会发生有害的界面反应，增强相体积分数也受到一定限制，产品性能低，性价比无明显优势。用此法生产镁基复合材料时应采取严密的安全措施。&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box;

margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;用此法制备镁基复合材料时，须先将增强材料与黏接剂混合制成预制坯，用惰性气体或机械设备作用压力媒体将镁熔体压入预制件间隙中，凝固后即成为复合材料，按具体工艺不同又可分为压力浸渗法、无压、浸渗法和真空浸渗法。可用挤压、铸造机进行浸渗，也可以用专用浸渗装备。增强相与镁熔体之间的浸润性对浸渗过程有重要影响，是关键的工艺参数。当浸润角θ＜90°时两相可以浸润，否则两者难以浸润。通常，镁熔体与陶瓷颗粒之间有较好的浸润性。另一个影响浸渗过程的工艺参数是预制坯中的胶粘剂。&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box;

margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;该法是将预制的镁粉或镁合金粉与陶瓷粒子均匀地混合为一体，经真空除气、固结成形后再进行压力加工制成所需形状、尺寸和性能的复合材料半成品。粉末固结工艺有热压和冷热、温等静压。此法主要优点：基体合金组织微细，可随意调控增强相的分数，甚至可高达50%左右，陶瓷颗粒尺寸可小于5μm，但不足之处是金属粉末在制备和贮存过程中易表面氧化，对材料塑性及韧性不利；制备大尺寸锭坯及需要大型设备和模具，投资较大；所采用的温度低，不会发生有害界面反应，有利于材料塑性及韧性提高。&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box; margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;&lt;br style=&quot;box-sizing: border-box;&quot;&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box;

margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;喷射沉积工艺是制备高性能合金材料的有效方法之一，若在喷射沉积过程中将陶瓷颗粒导入雾化锥中，与雾化颗粒共沉积，可以制得陶瓷颗粒增强的复合材料。喷射共沉积法制备AZ91、QE22合金/Al2O3或SiC颗粒复合材料的弹性模量、耐磨性都大幅度提高，膨胀系数有较大下降。&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box;

margin-top: 0px; margin-bottom: 0px; list-style: none; padding: 0px; line-height: 1.75em;&quot;&gt;由于喷射工艺流程短，材料制备比较简单、便利；增强颗粒在基体金属中分布均匀，界面反应很轻微，因而性能优异。QE22/SiCp复合材料锭坯孔隙体积分数高达20%，经挤压后，具有优异的强度和塑性，其伸长率达到12%，而传统铸造QE22合金的伸长率只不过2%。&lt;/p&gt;&lt;p style=&quot;box-sizing: border-box;

line-height: 1.75em;&quot;&gt; 珍珠岩是一种火山喷发的酸性熔岩经急剧冷却而成的玻璃质岩石。珍珠岩的主要工艺性能是其膨胀性，因此，珍珠岩的用途主要是膨胀珍珠岩的用途。&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);

font-weight: 700;&quot;&gt;二、珍珠岩的膨胀机理&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;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;珍珠岩之所以区别于其它岩石能够在一定的温度条件下膨胀，其主要原因不外乎两点根本原因。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&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;其一，珍珠岩的主要化学成分中存在软化点较低的玻璃质物质，即SiO2、Al2O3、Na2O等，这种物质表现出来的结果是当珍珠岩被加热至1000℃左右时，其玻璃质开始软化，珍珠岩颗粒从固态逐渐转化为黏流态。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&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;其二，珍珠岩内部含有的可挥发性物质和结合水在受到高温焙烧后，逐渐气化后溢出，所以，玻璃质是引起珍珠岩膨胀的先决条件，结合水是引起珍珠岩膨胀的内在动力，焙烧温度和时间是引起珍珠岩膨胀的必要外部条件。&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;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;缺点：&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;1.&lt;span class=&quot;Apple-tab-span&quot; style=&quot;box-sizing: border-box; white-space: pre;&quot;&gt;&lt;/span&gt;后期保温性能降低，易开裂，与基层粘结强度低易空鼓。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;2.&lt;span class=&quot;Apple-tab-span&quot; style=&quot;box-sizing: border-box; white-space: pre;&quot;&gt;&lt;/span&gt;膨胀珍珠岩吸水率高,耐水性差导致保温砂浆在搅拌中体积收缩变形大。&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);

text-align: center;&quot;&gt;&lt;img src=&quot;https://xue.cnpowder.com.cn/img/newsimg/2017/07/news_1499650509_8604.png&quot; style=&quot;box-sizing: border-box; border: 0px; vertical-align: middle;&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;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;相同点：&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;1.两者生产的原材料相同，都是来源于珍珠岩矿砂。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;2.都是高温膨胀后的制品，两者的化学成分相同，都耐酸碱、无色、无味、无毒，都属于建设部推广的A级防火材料。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;3.结构上都具备一定的微孔，因此都具备保温、隔热、吸声等特性，广泛用在建筑保温体系中。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&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;不同点：&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;1.结构的不同：膨胀珍珠岩是开放孔，玻化微珠是闭孔，所以玻化微珠又称闭孔珍珠岩。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;2.加工设备不同：膨胀珍珠岩是由煤气发生炉加热膨胀而成，而玻化微珠是由电炉膨胀而成。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;3.吸水率不同：玻化微珠不易吸水，膨胀珍珠岩吸水率很大，一旦吸水，膨胀珍珠岩的保温效果将大打折扣。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;4.容重不一样：膨胀珍珠岩一般在70-100kg/m3玻化微珠在110-130kg/m3。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;5.应用范围不同：玻化微珠主要用在外墙保温上，膨胀珍珠岩主要用在屋面及楼面保温上。&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;五、影响珍珠岩膨胀效果的主要因素？&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;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;影响珍珠岩膨胀效果的主要化学成分： &lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;(1) SiO2和Al2O3，它们是导致珍珠岩遇高温快速软化和在高温下保持一定粘度的主要化学成分；&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;(2) Na2O/K2O，该比值的增加可导致高温下珍珠岩粘度的降低，致使珍珠岩软化点下降；&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&quot;&gt;(3) Fe2O3+FeO，其含量的增加会导致珍珠岩膨胀倍数的降低。&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;六、膨胀珍珠岩保温板产生裂纹原因？&lt;/span&gt;&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em; text-align: center;&quot;&gt;&lt;img src=&quot;https://xue.cnpowder.com.cn/img/newsimg/2017/07/news_1499650509_9194.png&quot; style=&quot;box-sizing: border-box; border: 0px; vertical-align: middle;&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;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;珍珠岩保温板产生裂纹不外乎三种原因：干燥收缩裂纹，化学裂纹和荷载裂纹。&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;干燥收缩裂纹常出现在湿度差较大的部位，如表面系数较大的板式或壁式结构表面，大多为表面裂纹；化学裂纹主要为碳化收缩裂纹和碱骨料裂纹，其中碳化裂纹是混凝土在长期使用过程中，水化产物中的Ca(OH)2与空气中的CO2作用生成了CaCO3，碳化不但使混凝土的碱性降低，失去保护钢筋的作用，而且伴有体积缩小，形成碳化收缩。碱骨料裂纹是混凝土中的碱性物质同珍珠岩(富硅物质)中的SiO2发生反应而引起的体积变化，从而引发的裂纹；荷载裂纹出现部位多在混凝土结构的尺寸变化处，荷载不同的两结构连接处以及不同结构类型的两结构连接处。&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;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;目前我国膨胀珍珠岩在生产过程中都遇到三大难题，一是结炉，二是粉尘污染，三是膨化倍数低。实质上这是一个系统工艺技术问题。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&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;其一，结炉、粉尘多、膨化倍数低，虽然跟矿砂和炉型结构、膨胀温度有关，但同样的炉型，同样的温度，同样的矿砂，有的结炉现象和粉尘就少。生产过程中的计量给料等质量控制点都应受到重视。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&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;其二，一定温度区脱水、膨胀、熔溶均有一定时间要求，这就需要一个工艺平衡参数，结晶水的膨胀力直接关系到产品的膨化质量，所以目前许多厂家只重视膨胀炉，忽视预热炉，是极为不正确的。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&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;其三，矿砂的粒径的均匀性也有很大影响。在同一炉生产过程中结炉、粉尘大、膨化不好，关键因素在矿砂的粒径的均匀性和预热脱水量的均衡性，所以提倡矿砂分级使用，尽量减少矿砂的粉尘，提高矿砂粒径均匀性，重视预热脱水的均衡性是十分必要的，可提高产品的成品率,降低生产成本，同时提高资源利用率。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255); line-height: 1.75em;&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;其四，在生产过程中解决微粉的主要途径是通过提高矿砂的均匀性和预热脱水的均衡性，同时对收集工艺在旋风收集排放过程中，通过减压仓收集，降低风压流量和温度，排空时适当水淋和布袋过滤收集即可解决。&lt;/p&gt;&lt;p style=&quot;box-sizing: bord d-color: rgb(255, 255, 255);
