氫氧化鉀這種產(chǎn)品的使用比較普遍,特別是在化工行業(yè)的應用價值很高,這種產(chǎn)品的應用范圍這么廣,那大家又了解多少呢?接下來就給大家來具體講解一下耐火粘合劑的方法。
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.
在反應槽內順序加入8kg、粉末狀碳酸鈉(蘇打灰)(旭硝子株式會社制)7kg和金屬硅化物30kg,再加入60L的水。在其中開始自然反應,從下層的開始劇烈反應,在反應槽內從下側向上側發(fā)生對流。
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.
反應溫度自然上升,反應溫度在80~90℃的范圍內時,呈活躍的反應狀態(tài)。反應溫度不超過92℃。反應在10h左右結束,分離固體,可以獲得約48L(約70kg)耐火液。殘留的固體是金屬硅化物塊,如果用水洗凈,殘留約22kg左右的金屬硅化物塊。在這種殘存的金屬硅化物塊中,再補充加入約8kg左右的金屬硅化物塊,總和為30kg的金屬硅化物,供給到二次反應中。
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.
與一次反應同樣,在反應槽內加入8kg,粉末狀碳酸鈉(蘇打灰)(旭硝子株式會社制)7kg,接著,依次加入一次反應殘留的金屬硅化物塊22kg和新的金屬硅化物塊8kg,接著加入60L水,開始二次制備耐火液的反應。
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.
在制備中,按照加人顆粒狀氫氧化鉀,再加入粉末狀碳酸鈉(蘇打灰),再加入金屬硅化物塊,然后加水的加料順序,由下層開始反應,可形成上下對流式活躍反應,由此制備的耐火液性能較好。
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.
