According to an announcement published on the Ministry of Finance website, the tentative tax rate for exports of other rare earth metals, antimony and bismuth that are not mixed or fused with each other is 25% next year, and the temporary tax rate for other rare earth oxides is 15%.
Precision filter is mainly composed of filter container, support basket and filter bag these three parts. It's made of stainless steel. Flange precision filter is divided into 1,2,3 and 4 filter bags according to the size of the filter bag. Liquid inlet and outlet direction is divided into side in bottom out type and bottom in bottom out type.
When the precision filter is working, the liquid enters the filter bag supported by the supporting mesh frame from the interface. The filter bag will be evenly expanded to the periphery by the impact of the liquid, so that the liquid can be evenly distributed on the inner surface of the whole filter bag. The liquid passes through the filter bag and is discharged from the outlet at the bottom of the filter. The filter residue is left to be intercepted in the filter bag.
When the filter bag can be replaced after running for a long time, or when the pressure difference between the inlet and outlet reaches 0.05-0.07mpa during use, the filter bag also needs to be replaced.
