Pó de polimento de vidro 600# Pó de óxido de alumínio marrom

Óxido de alumínio fundido marrom, também conhecido como Brown Fused Alumina ou BFA, é produzido por meio de um processo de forno de arco elétrico. O óxido de alumínio fundido marrom é um material duro (dureza Mohs 9) e resistente com alta resistência, tornando-o uma excelente matéria-prima de grãos abrasivos para aplicações como mídia de jateamento, lixa, rodas de moagem e discos abrasivos, rolos, correias e almofadas. Suas propriedades térmicas o tornam uma excelente matéria-prima para aplicações refratárias também.

Reflective 90% roundness road marking glass beads for road marking paint

Reflective glass beads is the essential material for the coating of road marking, it is mainly used for road marking. The glass beads for road marking can improve the retro-reflective performance of road surface coating and increase the safety for night driving. When driving at night, the lamp shines on the marking line with glass beads in it, the ray of lamp is reflected back parallel. So the driver can look at the road clearly and drive safely at night.
