• PS Ball (Precious Slag Ball) PS ball grinders are widely used in many advanced countries for surface treatment of rust, ship hulls ... Uses as copper slag (nix granules). However, thanks to the latest Copper Slag Technology (SAT), the PS ball grinding wheel is the preferred solution because it is environmentally friendly, clean and quick to recycle. Most importantly, PS ball grinders are cheaper than nix grades because of the new technology that reduces production costs.
  • The FM-200 fire extinguishers are designed to be discharged within 10 seconds into a room, enclosure or enclosure with structural integrity to retain the agent. FM-200 is mixed in the protected area to a minimum level of compliance with the NFPA 2001 list. Fire protection areas Telecommunications facility Computer room Control room Museum Archive archive history Exhibition room Pharmaceutical and medical facilities Recordkeeping What is FM200? FM200 (FM-200®) is a clean, colorless, environmentally friendly, non-conductive and safe fire-retardant. It extinguishes the fire primarily through heat absorption, leaving no residue, thus minimizing downtime after a fire and making the FM200 suppression system acceptable and respected worldwide with over one hundred thousand installed in over seventy countries. Chemical properties of FM200 FM200 (HFC-227ea) is formed from the elements carbon, fluorine and hydrogen (CF3CHFCF3-heptafluoropropane). The main quenching mechanism of the FM-200® is the heat absorption, with secondary chemical contributions from the FM-200's thermal decomposition in flame. The FM-200 does not leave scum and is safe to use in occupied spaces. The most common metals, such as aluminum, brass, steel, cast iron, lead, stainless steel, and copper, as well as rubber, plastic and electronic components, are not affected by exposure to FM-200. Bien Dong Company supplies FM200 firefighting products and systems from original Kidde manufacturer from UK, US. The FM200 system was used on the rig of the customer partners.
  • PROPERTIES OF GRINDING GRINDING GRINDING The Steel Grit has 3 different hardness grades, which are applied to different needs: High hardness GH should only be used for compressed air systems. Two types of GL and GP have lower hardness that can be used for spraying systems. Generally used for deep grinding for details before plating, powder coating. Large grain is used for sanding for large and medium-sized castings. Small particles are used to clean products outside the molding industry ADVANTAGES: The angularity of the grain grain creates an etched surface on the metal for excellent adhesion of paint, epoxy, glaze, rubber and other coatings. A ton of slag (copper or platinum) produces about 28 kilograms of dust, while the corrosion of the steel produces a small fraction, which reduces the maintenance requirements of the filtration system when used in the spray booth. .
