氢氧化钾耐火粘合剂的方法!

发布来源:http://www.jinhao360.com    更新时间:2019-02-27 点击数:

  氢氧化钾这种产品的使用比较普遍,特别是在化工行业的应用价值很高,这种产品的应用范围这么广,那大家又了解多少呢?接下来就给大家来具体讲解一下耐火粘合剂的方法。

  Potassium hydroxide is widely used, especially in the chemical industry. This product has such a wide range of applications. How much do you know about it? Next, I will give you a detailed explanation of the method of refractory adhesives.
  在反应槽内顺序加入8kg、粉末状碳酸钠(苏打灰)(旭硝子株式会社制)7kg和金属硅化物30kg,再加入60L的水。在其中开始自然反应,从下层的开始剧烈反应,在反应槽内从下侧向上侧发生对流。
  Sequential addition of 8 kg, 7 kg of powdered sodium carbonate (soda ash) and 30 kg of metal silicide in the reaction tank, followed by 60 L of water. Natural reactions are initiated in the reactor, and severe reactions are initiated in the lower layer. Convection occurs from the lower side to the upper side of the reactor.
  反应温度自然上升,反应温度在80~90℃的范围内时,呈活跃的反应状态。反应温度不超过92℃。反应在10h左右结束,分离固体,可以获得约48L(约70kg)耐火液。残留的固体是金属硅化物块,如果用水洗净,残留约22kg左右的金属硅化物块。在这种残存的金属硅化物块中,再补充加入约8kg左右的金属硅化物块,总和为30kg的金属硅化物,供给到二次反应中。
  The reaction temperature rises naturally. When the reaction temperature is in the range of 80-90 C, the reaction state is active. The reaction temperature should not exceed 92 C. The reaction ends in about 10 hours and solids are separated. About 48L (about 70kg) refractory liquid can be obtained. The residual solid is metal silicide block. If washed with water, the residual metal silicide block is about 22 kg. In this remnant metal silicide block, about 8 kg of metal silicide block is added, and the total amount of 30 kg of metal silicide is supplied to the secondary reaction.
氢氧化钾
  与一次反应同样,在反应槽内加入8kg,粉末状碳酸钠(苏打灰)(旭硝子株式会社制)7kg,接着,依次加入一次反应残留的金属硅化物块22kg和新的金属硅化物块8kg,接着加入60L水,开始二次制备耐火液的反应。
  Similarly to the first reaction, 8 kg of sodium carbonate powder (soda ash) and 7 kg of sodium carbonate powder (Asahi Nitrate Co., Ltd.) were added in the reaction tank. Then, 22 kg of residual metal silicide and 8 kg of new metal silicide were added in turn. Then 60 L of water was added to start the reaction of preparing refractory solution twice.
  在制备中,按照首先加人颗粒状氢氧化钾,再加入粉末状碳酸钠(苏打灰),再加入金属硅化物块,然后加水的加料顺序,由下层开始反应,可形成上下对流式活跃反应,由此制备的耐火液性能较好。
  In preparation, according to the order of adding granular potassium hydroxide, powder sodium carbonate (soda ash) and metal silicide blocks, and then adding water, the reactions begin from the lower layer, which can form an active upward and downward convection reaction. The refractory liquid prepared by this method has better performance.
  以上就是给大家总结的关于制备氢氧化钾耐火粘合剂的方法,大家通过上面的内容可以大体了解一下制备方法,并且这种制剂可应用于厚纸板、聚苯乙烯泡沫塑料等,希望文中讲解的内容对大家有帮助作用。
  Above is a summary of the preparation of potassium hydroxide refractory adhesives. Through the above content, you can get a general understanding of the preparation method, and this preparation can be applied to thick cardboard, polystyrene foam plastics, etc. I hope the content described in this paper will be helpful to you.
