Preparation method of porcelainized compact honeycomb ceramic heat accumulator
The invention discloses a preparation method of a porcelainized compact honeycomb ceramic heat accumulator. The porcelainized compact honeycomb ceramic heat accumulator comprises a barren material anda clay plastic material. The preparation method comprises the following steps of: a, calcining an inorganic mineral raw material with high shrinkage rate to a sintered state, performing crushing to direct crush quartz, lithium chinastone and lithium feldspar to a certain particle size, modifying the clay plastic material by using a surfactant, adding a binder and deionized water, performing uniform mixing, pugging, and aging to obtain a mud section; b, extruding and molding the aged mud section into a green body; c, drying the green body; d, detecting, cutting and firing the dried green bodyso as to obtain the ceramic compact honeycomb ceramic heat accumulator. The shrinkage rate of the green body is reduced, and cracking is reduced; the high-temperature resistance is improved; the sintering temperature is reduced, the density of the green body is increased, the water absorption rate and the apparent porosity are reduced, and densification is achieved; extrusion molding is facilitated, firing is easy, the yield is increased, and the cost is reduced.
本发明公开了一种瓷化致密蜂窝陶瓷蓄热体的制备方法，所述瓷化致密蜂窝陶瓷蓄热体包括瘠性料和粘土类可塑性料，并包括下述方法步骤：a、先将收缩率大的无机矿物原料煅烧至烧结状态，然后破碎，所述石英、锂瓷石、锂长石直接破碎至一定粒径，同时用表面活性剂对粘土类可塑性料进行改性，再加入粘结剂和去离子水混合均匀，练泥，陈腐制成泥段；b、将陈腐的泥段挤制成型为坯体；c、将坯体进行干燥d、将干燥好的坯体检测切割烧制，获得瓷化致密蜂窝陶瓷蓄热体。本发明降低坯体收缩率，减少开裂；增加耐高温性能；降低烧结温度，增加坯体致密度及降低吸水率、显气孔率，达到致密化；便于挤出成型，易于烧制，提高良品率，降低成本。
