G-type asbestos dispersion prevention, non-thermal harmless treatment, and reuse.
Even after hardening, it does not contain organic solvents, so the original fire resistance and heat resistance effects are not lost!
The method for preventing the dispersion of G-type asbestos and its harmless treatment involves "dispersion prevention treatment" and "needle-like crystal destruction treatment." Through the chemical reaction of sodium silicate or potassium silicate, which are the main components of alkaline silicate solution, with calcium, magnesium, and aluminum ions contained in the cement used as a binder during asbestos spraying, glass substances are generated on the surface of the asbestos. By increasing the specific gravity through the enlargement of needle-like crystals and the bonding between them, dispersion is prevented. Furthermore, as the ion exchange reaction progresses, the generation of silicates and colloidal silica (glass substances) also advances, resulting in the densification of the crystals and an increase in hardness. Crushing this material will destroy the needle-like crystals. After crushing, it can be reused as cement raw material or ceramic raw material. *For more details, please refer to the PDF document or feel free to contact us.
