The two stages of sintering (that is, the evaporation period and the vitrification phase) are discussed. The free water in the evaporating period and the water on the surface of the material have been basically removed during the drying and drying process. Evaporation period refers to the removal of water of crystallization of the foam and the material. After sintering, the strength of the filter plate will be reduced, and even become waste products. A large amount of crystal water escapes from the material, and dissolution and diffusion occur between the low melting point and the user's three components of the material.
The ideal reaction is to generate fine aluminum aluminosilicates between the various components of the pellets, bonding the particles together to form a low adhesion. The amount of vitreous body should not be too much, according to the strict calculation of the ingredients. If the heating speed is too high at this stage, the ceramic layer will be destroyed, which will reduce the density and reduce the strength of the product. The industrial test proved that the foam ceramic filter plate developed by us has good filtration performance and good heat spread performance, achieving the intended purpose.
Conclusion (l) The main technical index of foam ceramic filter plates developed is 2.47 MPa, which is better than that of purchased products. The ceramic filter plate has a flat appearance, regular shape, no cracks, dregs, and other defects. Moreover, the pores are uniform and the blind hole rate is low. (2) After the porcelain paste is coiled, the cross-section is neat, and the inside and outside are elastic and uniform, which is in accordance with the relevant national standards; the thin strip after shearing has no obvious indentation.
As a result of the introduction of the disc knife cutting method and the second shear. Thus, while expanding the shear range of the thick box shearer, it also significantly improves the product yield. In addition, compared with the traditional thick box shears, the aluminum foil shearing machine has features such as high installation level, high machine speed, narrow shear width, large coil diameter, and good quality of cut coiling. Of course, further development of high-speed, precision, high-automation aluminum tip shears will be the development trend of future aluminum box shears.
