(2)氫氧化鉀耐火粘合劑的制備方法
(2) Preparation method of potassium hydroxide refractory adhesive
①耐火液制備方法:
① Preparation method of refractory liquid:
在反應槽內順序加入顆粒狀氫氧化鉀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,從下層的氫氧化鉀開始劇烈反應,在反應槽內從下側向上側發生對流。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。反應溫度高不超過92℃。反應在10h左右結束,分離固體,可以獲得約48l(約70kg)耐火液。
Add 8kg of granular potassium hydroxide, 7kg of powdered sodium carbonate (soda ash) (Asahi Co., Ltd.) and 30kg of metal silicide into the reaction tank in sequence, and then add 60l of water. The natural reaction starts from the potassium hydroxide in the lower layer, and convection occurs from the lower side to the upper side in the reaction tank. The reaction temperature naturally rises, and when the reaction temperature is within the range of 80-90 ℃, it shows an active reaction state. The reaction temperature should not exceed 92 ℃. The reaction ends around 10 hours, and the solid is separated to obtain approximately 48 l (approximately 70 kg) of refractory liquid.
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。與一次反應相同,在反應槽內加入顆粒狀氫氧化鉀8kg,粉末狀碳酸鈉(蘇打灰)(旭硝子株式會社制)7kg。
The remaining solid is a metal silicide block. If washed with water, about 22kg of metal silicide blocks will remain. In this residual metal silicide block, approximately 8kg of metal silicide blocks are added, totaling 30kg, and supplied to the secondary reaction. As for the first reaction, add 8kg of granular potassium hydroxide and 7kg of powdered sodium carbonate (soda ash) (made by Asahi Co., Ltd.) into the reaction tank.
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。在制備中,按照先加顆粒狀氫氧化鉀,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,由下層氫氧化鉀開始反應,可形成上下對流式活躍反應,由此制備的耐火液性能較好。
Next, 22kg of residual metal silicide blocks and 8kg of new metal silicide blocks were added in sequence, followed by 60l of water to begin the secondary preparation of refractory solution. In the preparation, granular potassium hydroxide is added first, then powdered sodium carbonate (soda ash) is added, then metal silicide blocks are added, and then water is added. The reaction starts from the lower layer of potassium hydroxide, which can form an up and down convection active reaction. The refractory liquid thus prepared has good performance.

②耐火膠黏劑的制備:
② Preparation of refractory adhesive:
將耐火液、裁斷的舊報紙(其它舊紙也可用)、稻殼、棉分別加入反應槽中,進行充分攪拌均勻即制得耐火材料。
Add refractory liquid, cut old newspapers (other old paper can also be used), rice husks, and cotton respectively to the reaction tank, and stir thoroughly to obtain refractory materials.
(3)這種耐火粘合劑性能若用耐火液涂覆木板,將涂覆的木板靠近1000~c火焰處30min不會發生燃燒。若將耐火膠黏劑混合物加壓脫水至45%水分含量,在180℃下加壓1h制得輕質耐火材料。
(3) If the performance of this fire-resistant adhesive is coated with fire-resistant liquid on the wooden board, the coated wooden board will not burn near a flame of 1000~C for 30 minutes. If the refractory adhesive mixture is pressurized and dehydrated to 45% moisture content, a lightweight refractory material is prepared by pressurizing at 180 ℃ for 1 hour.
將這種耐火材料靠近1500℃火焰觀察30min,10min后耐火材料表面發生陶瓷化,經30min燃燒后,切開耐火材料,陶瓷化深度僅o.8mm,火未通人耐火材料內部。此外,耐火材料隔音抗沖擊性能亦佳。其可切、鋸、釘釘子、釘螺釘等加工性能與木材類同。
Observe this refractory material close to a 1500 ℃ flame for 30 minutes. After 10 minutes, the surface of the refractory material undergoes ceramic transformation. After 30 minutes of combustion, the refractory material is cut open, with a ceramic transformation depth of only 0.8mm. The fire does not enter the interior of the refractory material. In addition, refractory materials have excellent sound insulation and impact resistance. Its processing properties such as cutting, sawing, nailing, and screwing are similar to those of wood.
