Production process of porous ceramic atomizing core containing titanium oxide
The invention discloses a production process of a porous ceramic atomizing core containing titanium oxide, which comprises the following raw materials in parts by weight: one or more of SiO2, Al2O3, Na2O, K2O, MgO, CaO, Fe2O3 and TiO2, SiO2, Al2O3, CaCO3 and MgO powder and pore-forming powder are mixed with paraffin and oleic acid, the mixture is stirred and mixed at 80 DEG C, the stirred mixed slurry is put into an injection molding machine, and the injection molding machine is used for injection molding of the porous ceramic atomizing core containing titanium oxide. The preparation method comprises the following steps: pouring the raw materials into a mold under a certain pressure to obtain a ceramic green body, degreasing and sintering the ceramic green body to obtain a ceramic matrix, silk-printing heating slurry on the ceramic matrix, and carrying out vacuum sintering to obtain the required ceramic atomization core. According to the production process of the porous ceramic atomizing core containing titanium oxide, titanium oxide ceramic is added into a ceramic matrix, in a sintering high-temperature state, part of titanium oxide can be dissolved in a liquid phase and generate Ti < 4 + >, the Ti < 4 + > can attract Ca < 2 + > ions or Mg < 2 + > ions, and disconnected O-Si-O bonds are reconnected, so that the ceramic matrix is obviously enhanced; the strength of the ceramic matrix can also be improved.
本发明公开了一种含有氧化钛的多孔陶瓷雾化芯生产工艺，包括以下重量份数配比的原料：SiO2、Al2O3、Na2O、K2O、MgO、CaO、Fe2O3和TiO2的一种或多种，将SiO2，Al2O3，CaCO3，MgO粉体以及造孔粉与石蜡和油酸混合，在80摄氏度进行搅拌混合，将搅拌的混合浆料放入压注机中，在一定压力下注模具中得到陶瓷坯体，将陶瓷坯体进行脱脂烧结，得到陶瓷基体，在陶瓷基体上丝印发热浆料，经过真空烧结后得到所需陶瓷雾化芯。该含有氧化钛的多孔陶瓷雾化芯生产工艺，通过在陶瓷基体中加入氧化钛陶瓷在烧结的高温状态下，部分氧化钛会溶解于液相当中并产生Ti4+，Ti4+会吸引Ca2+离子或Mg2+离子，并使断开的O‑Si‑O键重新连接，对陶瓷基体起到明显的增强作用，也能提高陶瓷基体强度。
