Jun porcelain biscuit cracking repairing glaze firing technology
The invention relates to the technical field of jun porcelain production, in particular to a glaze firing technology for repairing cracking of a jun porcelain biscuit. A Jun porcelain biscuit cracking repairing glaze firing technology specifically comprises the following steps that firstly, repairing supplementary materials are prepared, and raw materials of the repairing supplementary materials comprise high-temperature-resistant cotton powder, raw blank powder and white vinegar; the method comprises the following steps: a, repairing traces are obviously higher than the surface of the original porcelain, so that the repairing traces are prevented from being compressed uncompactly and shrunk after firing; step 2, drying; 3, biscuiting the green body again and finishing; 4, the Jun glaze proportion is adjusted, and the firing temperature rise curve is reduced; 5, anti-cracking glazing is carried out; and step 6, glaze firing, wherein the glaze firing temperature is 1200 DEG C. Compared with the prior art, the high-temperature-resistant cotton powder, the raw blank powder and the white vinegar are blended, and after the raw blank powder and the white vinegar with the same shrinkage rate are blended, no water absorption is achieved, and it is guaranteed that secondary cracking cannot occur when a biscuit is fired again.
本发明涉及钧瓷生产技术领域，更具体的说是涉及一种钧瓷素坯开裂修复釉烧技术。一种钧瓷素坯开裂修复釉烧技术，具体包括以下步骤：步骤一：调制修复用补料，所述修复用补料原料包括有耐高温棉粉、原坯份和白醋；a、修补的痕迹处要明显高于原瓷器表面，避免修补处填压不实，烧制后收缩；步骤二：干燥；步骤三：再次素烧坯体及修整；步骤四：调制钧釉配比，降低烧制升温曲线；步骤五：防开裂施釉；步骤六：釉烧，釉烧温度为1200℃。与现有技术相比，本发明通过耐高温棉粉、原坯份和白醋之间进行调和，通过收缩率相同的原坯份以及白醋调和后没有吸水率保证素坯再次烧制时不会二次开裂。
