Gypsum powder plant is a kind of micronized line which turns natural dihydrate gypsum ore (raw gypsum) or industrial by-product gypsum (desulphurization gypsum, phosphogypsum, etc.) into construction gypsum (calcined gypsum) through crushing, grinding, he
A manganese phosphate bath fluid is composed of manganese phosphoric acid water and an etching compound These baths are used for applying a conversion coating to metal parts mostly steel and manganese that are used in oily environments The manganese combines with phosphoric acid and the surface metal of the part to form a layer
After each cleaning phase the cleaning solution is routed to drain or back to the detergent tank for reuse A normal sequence could include initial water rinse lye cleaning intermediate water rinse acid cleaning and final water rinse followed by chemical or hot water temperature flow and detergent concentration in the CIP
It is very difficult to visually inspect the resin for iron and manganese fouling The best method to determine fouling is to soak a small sample in a 1 percent hydrochloric acid solution for five to 10 minutes If the acid solution has more than 5 ppm of iron the resin is fouled and requires cleaning
The presence of a strong chelating agent such as EDTA or DTPA can displace the metals making them soluble and easily removed by washing Manganese is found to be removed at greater than 90 efficiency with chelation or acid wash The optimal metal profile can be established with a chelation treatment under appropriate conditions of pH temperature time and charge
