Plastic Media

With over two decades of specialized experience in the Abrasive Media Industry

Plastic Media

Plastic media is a particle made of modern acrylic or polymerized thermosetting amines. The angular particle design is used for most dry strip surface films.

Provides effective processing methods. Plastic media has chemical indicators, and when used and recycled appropriately, this dry strip method can reduce hazardous waste, Self-leveling epoxy floor sand resin docking colored sand light floating sand floor special sand Plastic mediaing polymer material, premises, Produced by professional construction floor sand, it is low density, uniform and non-sinking, and can be used on 8mm thick floors.

1. Application scope of Plastic media abrasives:

Plastic media uses: surface treatment of workpieces, pretreatment before surface coating of workpieces, changing the mechanical properties of workpieces, and polishing processing of workpiece surfaces.

Plastic media application fields: aviation industry, shipbuilding industry, automobiles, high-speed trains, machinery manufacturing, molds, rubber, electronics and other fields.

The applications of Plastic media are as follows:

(1) Pretreatment (surface treatment) sandblasting before all covered processes such as electroplating, spraying, and painting;

(2) Cleaning: remove scale, residue, and dirt from metal workpieces such as castings, stampings, weldings, and heat-treated parts; clean and remove non-metallic surfaces.

From the hard shell containing carbon ash, etc.;

(3) Renovation of old parts: Renovation and cleaning of all moving parts of cars, motorcycles, mechanical and electrical equipment, etc., including paint and skin removal;

(4) Burr treatment: removal of tiny burrs on machined parts, and removal of burrs on the rubber surface (if applicable to the rubber tire field);

(5) Light decoration: all metal products and non-metal products (plastic, crystal, glass, etc.) have surface traces eliminated and matte matte treatment to make the product

The surface of the product is improved;

(6) Oilfield oil pipe cleaning, valve and pipeline cleaning, no static electricity or sparks will be generated during the cleaning process, ensuring safety during the operation


2. How to use resin sand abrasives:

Under a certain air pressure, granular polymer abrasives (resin sand) are sprayed onto the surface of the workpiece to achieve cleaning effects quickly and without damage.

–The gold-plated surface and plastic pattern parts will not be damaged during surface cleaning;
–The surface and size of the precision gold mold will not be affected;
–Non-toxic and dust-free;
–long lasting;

3. Precautions for resin sand abrasives:

  1. The gas tank, pressure gauge and safety valve of the sandblasting machine must be calibrated regularly;
  2. When the sandblasting machine is working at high speed, the abrasives flying out and the peeling materials on the workpiece may cause personal injury, so you must wear protective gear before working. Wear protective equipment;
  3. Resin sand should be stored in a dry and ventilated place, away from heat sources;
  4. Environmental protection requirements must be considered when handling waste abrasives.
