Uses and characteristics:
★ It is used for the precipitation and separation of phosphoric acid slag in wet-process phosphoric acid production. Through charge neutralization, the inorganic suspended particles in phosphoric acid rapidly lose stability. Meanwhile, through adsorption bridging, the suspended particles in the system aggregate into large particles or floc-like masses, thereby reducing the viscosity of phosphoric acid and accelerating the sedimentation speed of acid slag.
★ In the concentrated phosphoric acid added to this product, the concentrated phosphoric acid can be clarified very quickly. After gravity precipitation and stratification, the clarity of the acid liquid is greatly improved and the color becomes light.
★ The product is stable under the condition of 75~100℃ and phosphoric acid medium in wet process, and will not be degraded and failed due to heat or acid.
1. Preparation of reserve solution: it is best to prepare with desalted water. The recommended concentration of preparation is 1-2‰. When adding, it should be dispersed evenly and added slowly. It should be stirred at 100 rpm in the dissolution 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, the flow rate of phosphoric acid shall be calculated as about 5-10mg/L.
Packaging and storag：
20-25kg plastic woven bag or lined plastic paper bag packaging. Moisture-proof, heat-sensitive, storage period of 10 months, stored in cool, dry place.
Precautions for use：
★ The prepared product will be weakened in use for a long time and used up within the production cycle.
★ This product is a cationic and anionic balanced surfactant system. Do not add other surfactants or acids and alkalis 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 the skin or eyes, rinse immediately with plenty of water, and seek medical treatment if necessary.
★ 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.
