Blasting glass beads
Langfang Changfeng Glass beads are spheres of uniform size and hardness formulated of chemically inert soda-lime glass. They will clean surfaces and remove metal oxides without causing damage to the surface. Glass will not react chemcially with other materials. Then glass beads excellently suited for careful surface treatment, polishing, blast cleaning.
