Manufacturing method of liquid-permeation-resistant unglazed pottery jar for wine brewing
The invention discloses a manufacturing method of a liquid-permeation-resistant unglazed pottery jar for wine brewing, which comprises the following steps: (1) material selection: selecting pottery clay including nail mud and tender mud; (2) hydrophobic pretreatment on the tender mud: carrying out hydrophobic pretreatment on part of the tender mud to form a super-hydrophobic surface with a nano convex structure; (3) preparation of a mud cake: mixing the pretreated tender mud with other raw material components to prepare the mud cake; (4) a blank preparing process; 5) a drying process; (6) a firing process; and (7) pressure test detection. The part of tender mud is subjected to hydrophobic pretreatment to form a super-hydrophobic surface with nano bulges, the air permeability of the prepared unglazed pottery jar is not influenced, but the local section of an air hole channel of the pottery jar generates super-hydrophobicity, so that the permeation loss of wine in the brewing and aging process of the pottery jar is blocked, and the air hole channel still keeps the liquid storage property; therefore, the ageing effect on the wine is good, but the wine consumption is greatly reduced.
本发明公开了一种酿酒用耐液体渗透无釉陶坛的制造方法，包括以下工序：(1)选料：选取陶土，包括甲泥和嫩泥；(2)嫩泥疏水预处理：将部分嫩泥进行疏水预处理，使其形成具有纳米凸起结构的超疏水表面；(3)制成泥饼：将预处理后的嫩泥与其余原料成分混合，制成泥饼；(4)制坯工序；5)干燥工序；(6)烧制工序；(7)试压检测。通过对部分嫩泥进行疏水预处理，使其形成具有纳米凸起的超疏水表面，制得的无釉陶坛的透气性不受影响，但陶坛的气孔通道局部段产生了超疏水性，隔断了用该陶坛酿酒陈化过程中酒类的渗透损耗，气孔通道仍保持贮液性，故而对酒类具有良好陈化效果，但酒耗大大降低。
