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(yīng)用價(jià)值很高,這種產(chǎn)品的應(yīng)用范圍這么廣,那大家又了解多少呢?接下來(lái)就給大家來(lái)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(yīng)槽內(nèi)順序加入8kg、粉末狀碳酸鈉(蘇打灰)(旭硝子株式會(huì)社制)7kg和金屬硅化物30kg,再加入60L的水。在其中開(kāi)始自然反應(yīng),從下層的開(kāi)始劇烈反應(yīng),在反應(yīng)槽內(nèi)從下側(cè)向上側(cè)發(fā)生對(duì)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(yīng)溫度自然上升,反應(yīng)溫度在80~90℃的范圍內(nèi)時(shí),呈活躍的反應(yīng)狀態(tài)。反應(yīng)溫度不超過(guò)92℃。反應(yīng)在10h左右結(jié)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(bǔ)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(yīng)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(yīng)同樣,在反應(yīng)槽內(nèi)加入8kg,粉末狀碳酸鈉(蘇打灰)(旭硝子株式會(huì)社制)7kg,接著,依次加入一次反應(yīng)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(kāi)始二次制備耐火液的反應(yīng)。
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,按照首先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(kāi)始反應(yīng),可形成上下對(duì)流式活躍反應(yīng),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.
以上就是給大家總結(jié)的關(guān)于制備氫氧化鉀耐火粘合劑的方法,大家通過(guò)上面的內(nèi)容可以大體了解一下制備方法,并且這種制劑可應(yīng)用于厚紙板、聚苯乙烯泡沫塑料等,希望文中講解的內(nèi)容對(duì)大家有幫助作用。
