用挤膜成型工艺制备超厚雾化片的方法
摘要：
本发明公开了一种用挤膜成型工艺制备超厚雾化片的方法，属于制备压电陶瓷的方法。包括生料振磨、预烧、熟料振磨、配胶、制膜、生坯模压成型、排胶、烧结；其步骤如下：将瓷粉与水混匀、振磨；烘干后预烧结，得熟料；将所述熟料与水混匀、振磨；烘干后过筛，得熟瓷粉；将所述熟瓷粉、羟丙基甲基纤维素溶液、甘油、聚乙烯醇溶液、油酸、蓖麻油按比例混匀，得混合料；用挤膜机将所述混合料制成膜片；将所述膜片用模具压制成所需形状的生坯；将所述生坯在排胶烧结；将经过排胶烧结的生坯烧结成瓷片。用本发明方法制备厚度为0.6～1.5mm的压电陶瓷超声雾化片完全能够满足使用要求。
摘要（英）：

The invention discloses a method for preparing a super-thick atomization piece through a film extrusion forming process, and belongs to methods for preparing piezoelectric ceramic. The method comprises the steps of raw material vibrational grinding, pre-sintering, roasted material vibrational grinding, glue preparation, film manufacturing, green blank compression moulding forming, glue discharge and sintering. According to the following steps, ceramic powder and water are mixed uniformly and subjected to vibrational grinding; pre-sintering is carried out after drying, and a roasted material is obtained; the roasted material and water are mixed uniformly and subjected to vibrational grinding; sieving is carried out after drying, and roasted ceramic powder is obtained; the roasted ceramic powder, a hydroxypropyl methyl cellulose solution, glycerol, a polyvinyl alcohol solution, oleic acid and castor oil are mixed uniformly in proportion, and a mixed material is obtained; a film extrusion machine is used for making the mixed material into a film piece; the film piece is pressed into a green blank in a required shape through a mold; the green blank is subjected to glue discharge sintering; and the green blank subjected to glue discharge sintering is sintered into a ceramic piece. The piezoelectric ceramic ultrasonic atomization piece which is prepared through the method and is 0.6-1.5 mm thick can completely meet the use requirement.
