Two common types of ventilation used in spray painting are: Local exhaust ventilation captures the overspray and solvent vapour as close to the source of release as possible by drawing the contaminants into a capture hood. They should be fitted with a particulate filtration system to filter overspray. Wherever possible, local exhaust ventilation should be used when a spray booth cannot be used. It may be necessary to use it in combination with other control measures. Information on local exhaustRead More …

You should ensure that the plant and spray equipment used in spray painting or powder coating activities is well maintained, operational and clean. This includes: regular visual checks of equipment and plant, including engineering controls and ventilation systems regular monitoring and testing of ventilation flow rates regular servicing of all equipment and plant procedures for reporting and repairing faulty equipment records of servicing, maintenance, repair and testing of plant and equipment should be kept for future reference. When undertaking maintenanceRead More …

During powder coating application , the conditions for dust explosions must be paid attention highly to avoid any problem occur . A number of conditions must exist simultaneously for a dust explosion to occur. The dust must be combustible (as far as dust clouds are concerned, the terms “combustible”, “flammable” and “explosible” all have the same meaning and could be used interchangeably). The dust must be dispersed (forming a cloud in air). The dust concentration must be within the explosibleRead More …

How to maintain metallic effect powder coating Metallic effects arise through light reflection, absorption and mirror effect of the metallic effect pigments contained in the paint. These metallic powders can be used in both exterior and interior environments. The cleanability and suitability of the powder,for an environment or end use, starts with the colour selection process. In certain instances the powder manufacturer may propose the application of a suitable clear topcoat.The cleaning of metallic effect powder coated surfaces is inRead More …

Powder Coat Aluminum Comparing with conventional paint,powder coating is much more durable and is commonly applied on substrate parts that will be long term exposed to tough environments.That maybe worthwhile to DIY if there are lots of aluminum parts around you required for powder coating.It is no more difficult to buy a powder coating gun on your market than spraying paint . Instructions 1.Clean the part completely,removing off any paint,dirt or oil . Make sure that any components not to be coated (such as O-rings or seals) have been removed. 2.Mask any area of the part not be coated using high-temperature tape. For blocking off holes, purchase reusable silicone plugs that press into the hole. Mask large areas by taping on a piece of aluminum foil. 3.Set the part on a wire rack or hang it from a metal hook. Fill the gun’s powder container with powder no more than 1/3 full. Connect the gun’s ground clip to the rack. 4.Spray the part with powder, coating it evenly and completely. For most parts, only one coat will be necessary. 5.Preheat the oven to bake. Insert the part into the oven being careful not to bump the part or touch the coating. Consult the documentation for your coating powder about necessary temperature and curing time. 6.Remove the part from the oven and let it cool. Remove any masking tape or plugs. Notes: Make sure the gun is plugged into a properly grounded outlet. The gun cannot work without a ground connection.
