Uses and characteristics:
★ In the production of dilute acid filtration of wet phosphoric acid, the surface tension of phosphoric acid is reduced by the action of surfactants and polymer substances, and the clogging of filter cake capillary by organic impurities and particles is reduced, so as to improve the filtration effect.
★ The product has obvious filter aid effect on dilute acid slurry, which can significantly improve the filtration capacity of the system, improve the washing rate and increase the phosphorus yield. It is an efficient additive for wet phosphoric acid production.
★ The product is stable under the condition of 75-100℃ and phosphoric acid medium in wet process, and will not degrade and fail under the influence of heat and acid.
1. Preparation of reserve solution: it is best to prepare with desalted water, and the recommended concentration of preparation is 1-2‰. When adding, it should be dispersed evenly and added slowly. The solution should be stirred at a speed of 100 rpm in the tank to dissolve and be ready for use.
2. Continuous addition: transfer the reserve liquid into the dosing tank, open the metering pump, calculate the dosage according to the required amount, and let the agent continuously inject into the system.
3. The dosage shall be determined by experiment according to the site conditions. Generally, it is calculated as 5-20mg/L based on the slurry flow rate.
Packaging and storag：
25kg, 200L,1000kg plastic barrel packaging. Moisture-proof, heat-sensitive, storage period of ten months, stored in a cool, dry place.
Precautions for use：
★ The prepared product will be weakened in use for a long time, so it should be used up within the production cycle.
★ This product is a cationic and anionic balanced surfactant system. Do not add other surfactants or acids, alkalis, salts and other chemicals when using it, so as not to destroy its stability and affect the effect of the product.
Safety precautions：
★ Although this product is not corrosive and irritating, it should also be avoided from contact with skin and eyes. If it is stained on skin or eyes, rinse immediately with plenty of water. If necessary, seek medical treatment.
★ This product is not edible. If swallowed, please induce vomiting or seek medical attention immediately.
★ After use, rinse the residual material with clean water. The cleaning water can be added to the defoaming system. The cleaned packaging can be treated as general waste packaging. Under normal circumstances, the packaging is recycled by our company.
★ Product leakage should be avoided. If leakage occurs, flush with plenty of water and drain the flushing water into the sewage system.
