Supply precision casting high purity 100 mesh sand-blasting abrasive grains of sand

Supply precision casting high purity 100 mesh sand-blasting abrasive polishing abrasive powder of high purity 100 mesh sand moderate hardness, toughness, uniform particle size, is a good natural abrasives. In the optical industry, electronic industry, machinery industry and other industries are widely used. Such as: (1) high-pressure water jet equipment (waterjet) cutting abrasive; (2) sand-blasting, cutting, special welding and thermal spraying, manufacture wheel, Whetstone, emery cloth, sandpaper materials; (3) as the water filter media treated; (4) silicon, optical lenses, precision instruments, polished glass, glassware, ceramics, stone, leather, plastic, metal parts can improve the finish; (5) can be used as construction of motorways, aircraft runway, wear-resistant rubber, industrial floor paint and other comparatively good wear non-slip material; (6) can be used for chemical, petroleum, pharmaceutical, water treatment filter media and drilling mud weighting agent; (7) can be used as washing plant jeans sandblasting sand and other precision casting workshop include: investment casting, ceramic mold casting, metal casting, pressure casting, lost foam casting. One of the more commonly used investment casting, also known as the lost wax casting: the choice of suitable investment casting material (such as paraffin) made investment casting; in the investment casting refractory repeated dip coating and sprinkled sand refractory process, shell hardening and drying; Then internal investment casting melt away, get baked shell cavity in order to obtain sufficient strength, and burn residual melt molding materials; casting metal material required; solidification cooling, after shelling sand, to obtain a high the accuracy of the finished product. Depending on the product needs or heat treatment and cold working and surface treatment.
