Hot sell glass beads abrasive for sandblasting PV:2321
-
Category:Aluminum Oxide
SPEC:80mesh
Packaging:Bag Package/Small Bag Package
The glass beads, composed of SiO2,Na2O and CaO,
are broken and calcined by high temperature after which the said microspheres
are obtained. With properties of the high roundness rate, better hardness, excellent
anti-friction and direct reflect light ,etc, they are widely applied in the
fields of plastic rubber, abrasion ground, blast derusting , road-reflect dope
and handicraft lamp, etc
