About Abrasive Filament
DAMI abrasive filaments are produced by loading abrasive grits such as silicon carbide (SIC) or aluminum oxide (AO), Diamond evenly into high-quality nylon and extruding the mixture into filaments.
DAMI abrasive filaments have superior stiffness, good flexibility, and great elasticity. Brushes made with DAMI abrasive filaments are highly efficient in grinding, finishing, polishing, and deburring in different industries and for different surfaces e.g. curved, concave, convex surfaces or insides of pipes without damaging the dimensions and fineness of the workpiece.
Silicon Carbide (SIC)
Common used abrasive grit is silicon carbide aka SIC grit, which is produced in a resistance type electric furnace with petroleum coke, quartz sand and other materials. SIC is an extremely hard black insoluble crystalline substance. It is used as an abrasive and heat-refractory material and in single crystals as semiconductors, especially in high-temperature applications. Its micro hardness is HV3100-3280, stiffness and hardness is higher than White Alumina. SIC abrasive filament can be widely used to produce industrial brushes for steel, textile, PCB cleaning, stone polishing, and other grinding applications.
PROPERTY COMPARISON OF GRIT
- Vickers hardness (HV): DM > SIC > AO
- Cutting force: DM > SIC > AO
- Price: DM > SIC > AO
PROPERTY COMPARISON OF NYLONS
Bend recovery: PA6<PA610<PA612
Water absorption: PA612<PA610<<PA6
Durability:PA6<PA66<PA610<PA612
FIELD OF APPLICATION:
Abrasive filament mainly used in steel cleaning,wood polishing,stone surface treatment,textile sanding,circuit board polishing,hardware polishing,liquid crystal surface polishing and other fields.
- Surface processing of cooper or aluminum rolls
- Deburring for automobile hug,gear,and engine parts.
- Precision processing for compressor parts of refrigerator and air-conditioner
- Deburring after mechanical treatment and chamfering
- Polishing for the surface of die casting
- Deburring for the inner wall of hole
- Polishing for the surface before electroplating and coating
- Cleaning for militar y weapon
- Cleaning and polishing for PCB circuit board
- Textile sueding process and jeans cloth discoloration
- Polishing for stone antique surface,furniture,etc
- Polishing brushas tools of angle grinding,pneumatic tools,etc.
THE BEST ONE IS THE MOST SUITABLE ONE
The most popular abrasive filaments are SIC and AO filaments. SIC abrasive is generally the best choice for the most of the applications. AO is suitable for precision polishing and soft surface. Basically, every industry has its own common-used abrasive filament. For detailed questions, please do not hesitate to contact us for consulting. It would be more helpful, if you can send us some samples for analyzing.
