Manufacturing porous alumina ceramic foam filters, using a three-dimensional network structure and organic foam sponge connected to the pores as a carrier, invading it into a special ceramic slurry with thixotropy, and uniformly coated by a special roll extrusion process The skeleton of the ceramic paste to the carrier. Then, it is dried and cured and then fired at a high temperature to complete.
When choosing Porous Alumina Ceramic Foam Filters, it is more necessary to evaluate the useful value of the foam more closely than the calculation of the appearance and porosity of the product. The uniform state of the grid can be checked on the outer surface of the ceramic filter plate, and the uniform state of the cross-sectional grid can be checked. When the conditions are met, the porosity can be measured and calculated according to the drainage situation. The three-dimensional network structure is uniform and the porosity is large, making it a better ceramic filter plate.
To choose Porous Alumina Ceramic Foam Filters, observe its color, hit its body, and burn its objects. Pure color, variegated color, uniform material. On the other hand, hold the filter plate with one hand, tap the filter plate gently, and tap the filter plate appropriately. The ceramic slag is continuously lost. The inferiority of the filter plate is obvious, the aluminum liquid causes secondary pollution. Use open flame and electric heating to burn to red, and immediately cool to room temperature without tilting or wearing. It is said to be a good filter plate.
The casting quality is required to be high, and a new type of alumina ceramic foam filter with small holes and large meshes is selected. The selection of ceramic filter plates is based on the flow rate of the molten metal and the total flow rate. Choose filter plates with large flow, large capacity, small holes, and large size.
When you choose any item, we want to choose all cost-effective items. That is to choose products with high quality, good quality, and long life. The choice of ceramic foam filter plates is no exception, and the efficiency of ceramic foam filter plates is expected to increase. So, do we choose ceramic foam filter plates to ensure high efficiency?
All our processes are under the supervision of the ISO9001 quality system certificate. Each test is self-checked by a full-time inspector. In order to ensure the quality of the filter, appearance and strength tests must be performed.
