Scope

Scope: This document specifies the technical requirements, test methods, inspection rules, marking, labeling, and accompanying documents, as well as packaging, transportation, and storage for polyvinylidene fluoride (PVDF) used in water treatment membranes. Main technical content: Polyvinylidene fluoride used in water treatment membranes serves as a membrane separation material, featuring high mechanical strength, good thermal stability, and chemical resistance, as well as excellent filtration performance and long service life. It is primarily used in wastewater treatment, seawater desalination, and drinking water purification. The thermal decomposition temperature of polyvinylidene fluoride used in water treatment membranes exceeds 380°C, with a weight-average molecular weight of 800,000 to 1.2 million and a molecular weight distribution index of less than 3.0. Other indicators include melting temperature, particle size, solubility, and specific viscosity, which better meet the application requirements of polyvinylidene fluoride in the field of membrane separation for water treatment.
