Dry-pressing and Isostatic Pressing
The production process of zirconia ceramic rod dry pressing and isostatic pressing can be intuitively understood as: dry pressing is formed by pressing the front of the press; isostatic pressing uses a high-pressure vacuum isostatic press, compressing from the side Forming can achieve isostatic pressing. The biggest difference between the two molding processes is that the produced zirconia ceramic rods have different backing pattern structures, while the isostatic pressing process can produce different backing pattern structures. For example, the distinctive swallowtail pattern on the macaroni ceramic rod. This special "wide inside, narrow outside" structure greatly improves the grip of zirconia ceramic rods and walls during the laying process, thereby expanding the application field of zirconia ceramic rods. Can be used wet glued to the exterior walls of buildings.
The isostatic pressing process also has special requirements for the embryo of zirconia ceramics. The main requirements are dry strength, plasticity and water absorption of the green body, which is the basis for isostatic pressing. In addition, raw materials with abundant reserves and stable quality should be selected, especially to meet the performance of sludge.
According to reports, compared with zirconia ceramic rods produced by dry pressing technology, zirconia ceramic rods produced by isostatic pressing technology have their own advantages. Zirconia ceramic rods produced by isostatic pressing have higher hardness and toughness, while dry pressing produces faster. At present, the bottleneck of isostatic pressing technology is mainly limited in production capacity and performance.
