陶瓷制品在成型工艺过程中,由于调合料的塑性、干燥处理和操作技术问题所造成的毛病以各种坯裂为最多.在半制坯上各种比较细小的裂纹,往往因不易发现而混送入窑,无形中在烧成上增加了废品率,或在成品上产生细小裂纹降低了质量等级.因此半成品裂口的问题最大,影响入窑后成品率升降的关系也最为密切. 在窑业上一般都熟悉采用火油检查毛坯或精坯的方法来防止裂坯入窑,但是它的缺点是在呈色的坯体
Ceramic products in the molding process, due to the plasticity of the blending material, drying and handling problems caused by the technical problems of the various billet cracks. In the semi-finished billet, a variety of relatively small cracks are often not easy to find. Mixed into the kiln, virtually increase the scrap rate in the firing, or produce small cracks in the finished product to reduce the quality level. Therefore, the problem of the semi-finished product crack is the largest, affecting the relationship between the rate of increase and decrease in the rate of entering the kiln is also the closest. The industry is generally familiar with the method of using fire oil to inspect the blank or the blank to prevent the crack from entering the kiln, but its disadvantage is that the green body is colored.
