The effect of clay content for pruducing alumina-based ceramic foam filters

Alumina-basedceramic foam filterswere prepared by organic foam impregnation. The effect of clay content on the properties of ceramics was studied. The results show that with the increase of clay content, the thermal shock stability of the samples increases first and then decreases, and t […]

Adtech degassing unit and ceramic foam filter helps to produce higher specification aluminum foil for lithium batteries

It is understood that in addition to Nanshan Aluminum, Dongguang Technology, Dingsheng New Materials, and Mingtai Aluminum(Mingtai Aluminum using Adtech's degassing units, ceramic foam filters, and caster tips.), there are also Yongjie New Materials(Yongjie new materials' 15 production lines are made in Adtech, such as degassing units, ceramic foam filters, and caster tips.), Fulaishun, Hangzhou Five Star, Huaxi Aluminum, Sifangda, Zhongnan Aluminum, Shanghai Alcoa, as well as aluminum foil suppliers such as Zhenxin Foil Electronics, and only a few manufacturers have high technical indicators. […]

Battery aluminum foil demand increasing requires more ceramic foam fitlers

"In this year, the company's battery aluminum foil orders have grown steadily, and the product supply is in short supply. In July, customers temporarily added more orders, and the total order volume reached more than 11,000 tons. Due to the lack of time to adjust the production line, the to […]

The principle of filtration of molten aluminum and the choice of ceramic foam filtersThe principle of filtration for molten aluminumThe characteristics of ceramic foam filter plate are similar to activated carbon, it has the characteristics of a multi-layer network multi-dimensional through-hole, an […]

What is BN coating

Boron nitride is a crystal made up of nitrogen atoms and boron atoms. The chemical composition is 43.6% boron and 56.4% nitrogen, with four different variants: hexagonal boron nitride (HBN), rhomboid boron nitride (RBN), cubic boron nitride (CBN), and fibrozinite boron nitride (WBN). Variants of its […]

Improvement of Adtech ceramic foam filters

Along with the development of science and technology, the industrial aluminum manufacturer has higher and higher requirements for the purity and quality of aluminum and its alloy materials, but the traditional refining and degassing process cannot remove the fine and suspended non-metallic inclusions in melted aluminum. […]

The linear shrinkage of the alumina ceramic foam filter

The linear shrinkage of the alumina ceramic foam filter is shown in Table1. It can be seen that the linear shrinkage rate of alumina ceramic foam filters is below 1% under different aluminum dihydrogen phosphate content, and the linear shrinkage rate increases slightly with the increase of aluminum dihydrogen phosphate content. […]

Reasons for broken ribs and collapse of ceramic filter plates.

In the process of making the ceramic foam filter, the aluminum dihydrogen phosphate solution is used as a binder to stick the alpha alumina powder on the polyurethane sponge. […]

Ceramic foam filters making method

Polyurethane sponges were dipped into a slurry prepared with fused alumina powder and aluminum dihydrogen phosphate in order to obtain the green body. Ceramic foam filters were fabricated by pyrolysis of the green body at 800℃. […]

Ceramic foam filter uses

The production of ceramic foam filter uses a three-dimensional network structure and organic foam plastic with connected pores as a carrier, which is immersed in a special ceramic slurry with thixotropy, and a special rolling process is adopted to make the ceramic slurry. It is evenly applied to the skeleton of the carrier, then dried and cured, and then fired at high temperatures. […]
