点击图片查看原图Calcined petroleum coke
our company is the production of friction materials for petroleum coke with high quality petroleum coke calcining temperature 1300℃above eight fire road room twenty-four concurrent pot calciner. Is black or dark grey hard solid products, with a metallic luster, porous graphite crystal formation, is
composed of tiny carbon precursors of granular, columnar or needle-like.
The technical index of imported products to:
( 1 ) little Density, loose, porous.
( 2) with high carbon content, less volatile, physical and chemical properties are very stable.
（3）according to the foreign material and product manufacturing, and the strict screening, it has fixed for friction material granularity. Friction material used petroleum coke can reduce the product weight ( density ), improve the product porosity and compression performance, thus make the friction stabled performance, improve brake’s degree of comfort and process performance, what’s more is that reduce the braking noise.
Recommended dosage: disc brake 6-8%、 drum brake linings 4-6%
Mesh: our company can provide the appropriate mesh according to the requirements of the buyer
