<p class="summary"> 耐火浇注料的表面活性剂是一种能显著改动流体表面张力的活化剂，它将少数表面活性剂与耐火注射剂混合，显著改动资料界面间的表面能，并起到潮湿、成型、分散、减水的效果，释放等等。 离子型分红三种类型：水地型、中性型和负离子型。非离子名义活化剂是一种没有正在水中离子化的含氧基团，如脂膏醇聚氧乙烯醚，没有带电，没有发生强吸附现象，且作为含氧基团。 浇注料是一种颗粒状和...</p>

<p class="summary"> 控制物料循环量是循环流化床锅炉运行操作时不同于常规锅炉之处。根据循环流化床锅炉燃烧及传热的持性，物料循环量对循环流化床锅炉的运行有着举足轻重的作用，因为在炉膛上部，使炉膛内的温度场分布均匀并通过多种传热方式与水冷壁进行交换，因此有较高的传热系数。 通过调整循环物料量可以控制料层温度和炉膛差压，并进一步调节锅炉负荷。物料循环量增加可使整个燃烧室温度分布趋于均...</p>

<p class="summary">低水泥浇注料是指含结合剂量很少的新型浇注料。关键之处在于采用不超过1μm的超细颗粒。其耐热震性、抗渣性、抗侵蚀能力显著提高，超过同类耐火砖。进一步降低结合剂含量可制得超低水泥浇注料和无水泥浇注料。 低水泥浇注料是指水泥用量较低的浇注料。耐火水泥浇注料的水泥用量一般是15%～20%，低水泥浇注料的水泥用量则是5%左右，有的甚至降低到1%～2%。降低水泥用量的目...</p>
