Use

1. metal purification Using citric acid as the base metal cleaning formula, can effectively remove the oxides formed on the surface of ferrous and non-ferrous metals, as a weak organic acid, It can cause slight damage to the surface of the metal layer. However, as a metal ion chelating agent accelerated the migration of metal oxide, the acid system in many steel padding, in order to eliminate the metal oxides rift and the erosion of high strength steel embrittlement decreases to a minimum level, by citric acid rust to replace inorganic acid. In the boiler, heater, superheater tubes and clean the reactor and stainless steel equipment commonly used citric acid pre-washing and cleaning to remove iron, copper oxide, especially where chloride is not permitted. Citric acid solution purification reaction is higher than that under the condition of 37.8℃, below 37.8℃ purification time should be extended accordingly. By the estimated precipitation increase or decrease in the amount to adjust the dosage of citric acid and changing conditions. Citric acid is an efficient chelating cleaning agent, the calcium, magnesium, iron, chromium, copper and other dirt effective, widely used for a variety of metal surface cleaning, washing wastewater can be biodegradable non polluting environment. In recent years, citric acid is applicable to metal purification of chemical processing, and is suitable for the waste solvent without pollution of podzolization, in ash molecular burning of citric acid into CO2 and water vapor and valuable metals can be recovered from the ash for toxic or radioactive elements can be closed for chemical treatment. 2. detergent Sodium citrate could increase decontamination performance. In many household detergent products may be accelerating biodegradation, which can be used as a substitute for phosphate, a large number of applications in detergent, cleaning agent, citric acid and sodium aluminum silicate together with an enhancement of detergent cleaning is very effective. This kind of products use industrial grade of 50% citric acid solution as raw materials. In the synthesis of non detergent solution, because citric acid buffer action and chelated trace metal ability, hence also for hot water extraction of the carpet cleaner, bubble bath and textile softener. 3. non soil cultivation In foreign countries use trace element nutrient liquid for plant soilless culture, which has been very common, at home also began development. In order to remove some copper in soil, excess zinc, manganese, chromium and other elements, the general use of citric acid chelate such elements. Using citric acid instead of phosphate can achieve satisfactory effect on increasing yield. 4. Application of minerals and pigments Citric acid has distributed performance, it can reduce the viscosity of some important slurry raw material. In mining areas such as phosphate rock powder in hydraulic transport viscous problems often become the main reason for the expansion of clay, the citric acid treatment can control the expansion, the raw slurry is easy to transport. Citric acid can also reduce the precipitation concentrated raw material from titanium dioxide the ease of handling and to the overall form of transport. Citric acid can also be used for low Pulp Sizing, paint and textile raw materials processing and TiO2 dispersions.
