Production process of phosphorus containing reverse osmosis scale inhibitor

The production process of phosphorus containing reverse osmosis scale inhibitors generally includes the following steps:

Raw material procurement and storage: According to the product formula, purchase the necessary raw materials, including phosphoric acid, amine compounds, corrosion inhibitors, additives, etc. The raw materials need to be stored in a dry and ventilated warehouse to prevent the invasion of moisture and pollutants.

Ingredients and mixing: According to the formula proportion, weigh the required raw materials and add them to the reaction kettle or mixing tank. According to the process requirements, add appropriate solvents or auxiliary substances to promote the reaction and mixing effect.

Reaction: After mixing the raw materials, proceed with the reaction. The reaction conditions include temperature, pressure, stirring speed, etc., which need to be determined based on specific product and process requirements. During the reaction process, it may be necessary to gradually heat, cool, or control the pH value.

Filtration and separation: After completing the reaction, the mixture is filtered to remove solid impurities and unreacted substances. Commonly used filtering equipment includes filter cloth, filter paper, filter press, etc.

Concentration and drying: Concentrate the filtered liquid to increase the solid content of the product. The concentration method can include evaporation, crystallization, etc. The concentrated products need to be dried, usually by spray drying or airflow drying.

Packaging and quality inspection: After drying, the product is packaged and subjected to relevant quality inspections. The quality inspection content includes the detection of indicators such as appearance, solid content, pH value, solubility, etc.

The above is the general production process of phosphorus containing reverse osmosis scale inhibitors, and the specific process details and conditions may vary depending on the characteristics and requirements of the product. During the production process, it is necessary to strictly comply with safety operating procedures and environmental requirements to ensure product quality and production safety.
