Cleaning steps for chemical nickel filters

Update time : 2023-07-10 23:48:05

Chemical nickel filter is a special filter used to filter chemical nickel. After daily use for a long time, there will be nickel precipitation in the filter bucket. Jiangsu Baobao Xiaobian for you to summarize a set of effective cleaning nickel precipitation steps ~

Chemical nickel filter medicine tank cleaning:

First wash the inside and surface of the cylinder with clean water, and then soak the cylinder with 30% nitric acid until it is dissolved in the cylinder.

Collect nitric acid in the cylinder and clean the cylinder body twice with clean water; Then soak the cylinder with 60g/L trisodium phosphate solution for 30 minutes. At this time, the PH of trisodium phosphate can be measured with a PH meter. If the PH is lower than 10.5, the trisodium phosphate needs to be replaced; Resoak in the new trisodium phosphate solution for about 30 minutes.

Then clean the cylinder twice with water, and soak the cylinder with 10% sulfuric acid for about 30 minutes.

Then clean the cylinder twice with clean water. Finally use deionized water (pure water) to clean the cylinder once.

Chemical nickel filter cleaning:

First clean the inside and outside surface of the filter with tap water (remove the filter element). With a tank of 30% nitric acid, the filter inlet and outlet are placed in a small tank (the nitric acid in the small tank is collected for water, and the filter is recycled for about 10 minutes, and then the water is recycled for 10 minutes.

Fill a small tank with 60g/L of trisodium phosphate solution and wash it in a filter cycle for 30 minutes. At this time, if the PH of the trisodium phosphate solution measured with a PH meter is lower than 10.5, the trisodium phosphate needs to be replaced. Resoak in the new trisodium phosphate solution for about 30 minutes.

Then filter with clean water twice (10 minutes each time); Then filter with 10% sulfuric acid water cycle for 30 minutes; Filter with clean water for 2 times (10 minutes each time); Finally, it is filtered once (10 minutes each time) by removing water circulation.

The above is the method and step of how to clean the precipitation in the chemical nickel filter summarized by Jiangsu Baobao Xiaobian. Did you learn it? If you have other questions about the filter, welcome to Jiangsu Plating Bao Xiaobian Oh ~
