GF Filter Membrane
A GF filter membrane is made of 100% borosilicate glass fiber, with capillarity fiber structure, which can absorb more water than the same fiber filter paper, with fast flow rate, high bearing capacity, high-temperature resistance, and can very well retain fine particles.
A GF filter membrane has the characteristics of non-hygroscopicity and biological inertness and is resistant to chemical corrosion of most solvents and reagents except hydrofluoric acid and high concentration of the acid-base solution.
1. Used for daily air pollution monitoring;
2. The collection of high-efficiency fine particles;
3. Used for water pollution analysis;
4. Dust collection in the air.
A GF filter membrane without binder is usually used for filtering fine particles, which is divided into six grades: A, B, C, D, F, and H.
Binder can enhance the mechanical strength of a GF filter membrane that is mainly used to filter coarse particles (such as macromolecular substances and dust). In order to avoid chemical reactions with the filtered substances, the glass fiber with the inorganic binder is selected when filtering organic substances and the glass fiber with an organic binder is selected when filtering inorganic substances. The most common grades are 6, 8, 9, and 10.
