Sponge ceramic tube and preparation method thereof
The invention relates to a sponge ceramic tube and a preparation method thereof. The sponge ceramic tube is prepared from the following raw materials: 58-62% of aluminum oxide; 35-39% of silicon oxide; 0.6%-1.2% of iron oxide; 0.4 to 0.9 percent of kaolin; 0.4 to 0.8 percent of calcium carbonate; 0.6% to 1.2% of potassium feldspar; and 0.3-0.9% of magnesium carbonate. The preparation method comprises the following steps: preparing the base material according to the raw materials; introducing the basic material into a stirring device for stirring, adding emulsified paraffin into the stirring device, and continuously stirring to obtain slurry; injecting the slurry into a ceramic tube type blank by adopting an injection device, and naturally drying after forming a parison to obtain the parison; the parison is introduced into a kiln for dewaxing, and a dewaxed sponge ceramic pipe blank is obtained; and the dewaxed sponge ceramic tube blank is introduced into a high-temperature sintering furnace to be sintered, discharged out of the furnace and cooled, and the sponge ceramic tube is obtained. The sponge ceramic tube is rapidly deformed under the action of external force and rapidly recovered after the action of external force disappears, the constant-temperature heat storage effect is good, and high temperature resistance is achieved; the process steps are short, and the large-scale production requirement is met.
一种海绵陶瓷管及其制备方法，由以下原料构成：氧化铝58‑62%；氧化硅35‑39%；氧化铁0.6‑1.2%；高岭土0.4‑0.9%；碳酸钙0.4‑0.8%；钾长石0.6‑1.2%；碳酸镁0.3‑0.9%。步骤：按上述原料配取基础料；将基础料引入搅拌装置中搅拌，再向搅拌装置中加入乳化石蜡继续搅拌，得到浆料；采用注射装置将浆料注入陶瓷管型坯中，出型坯后自然干燥，得到型坯；将型坯引入窑炉脱蜡，得到脱蜡的海绵陶瓷管坯；将脱蜡的海绵陶瓷管坯引入高温烧结炉烧结，出炉并冷却，得到海绵陶瓷管。使海绵陶瓷管在外力作用下快速变形且在外力作用消失后快速复原，恒温蓄热效果好，耐高温；工艺步骤简短，满足放大生产要求。
