In the finishing industry, there is a real link between safety and quality-especially with regards to spray booths, which can run the risk of causing fire if not properly maintained. Equipment for dust collection is strategically created to meet specific needs with regards to performance, such as airflow velocity; fan, filter and burner capacity; and safety pertaining to fire prevention and operator wellbeing.
However, after the manufacturer ships the equipment, installation, operator training and maintenance end up being the responsibility from the finisher. Therefore, it is recommended to give the High Quality Furniture Paint Spray Booth China and associated processes a thorough review for fire safety hazards along with other incidents that may occur.
Dust Collection – There are 2 sides of dust collection: quality and safety. An exceptional finish is definitely the direct consequence of adequate removing of airborne particles that may contaminate finished surfaces. This contamination causes rejects or rework of product which brings about lost profits.
It’s not just surface finish that particle build-up could affect, though. Otherwise cleaned, particles can migrate to areas where operators might not have proper breathing protection, and fire turns into a real hazard. Sufficient airflow is essential.
The top causes of fire in dust collection systems include: static electricity discharge, exothermic reaction as a result of chemical reaction of collected dust,
cutting or welding too near the area.
In essence to accumulate the dust with a well-designed dust collection system that boasts a smart layout and balanced air replacement. As suggested by the National Fire Prevention Association (NFPA): “Air flow must be carefully considered.” Criteria for dust collection processes usually include air velocity in the booth of 125 to 150 FPM. If properly filtered, this air may be recycled into the facility. Clean air dilution ratios to get a facility also have to consider heat, off-gases, and odors from ancillary processes including sanding or grinding.
Additionally, doors or pressurized plenums may be used to contain dust. A good investment in containment is going to be reflected in less cash spent on cleaning and correcting finish rejects.
Spray Finishing Systems and Booths – Inflatable Spray Paint Booth For Cars have several their particular specific requirements for safety and quality. First, sufficient and laminar airflow is required in order that the exhaust can capture overspray and pull it to the filtration systems, which may be either a dry filter or perhaps a water wash. To get rid of particulate through the air, the right filter media or chamber is essential. Then, the new air supply needs to be not only clean, but in addition at the correct temperature. More sophisticated coatings could also require humidity control. Not to mention, all equipment needs to be properly grounded.
The best fire prevention may begin with understanding of so what can produce a fire in a spray booth. In a conventional system, main reasons for fire include:
using spark-producing equipment such as cutting, welding or grinding close to the spray area; friction, in most cases due to overheated bearings on the exhaust fan, or by rubbing of exhaust fan blades against overspray deposits on the wall in the duct; arcing electrical equipment;
spontaneous combustion; and discharge of static electricity.
In electrostatic spray operations, main reasons for fire include: ungrounded or improperly grounded objects within the spray area, failure to totally discharge equipment before cleaning, pinhole leaks within the paint tubing for the spray gun, other causes much like conventional systems including smoking, cutting and welding.
All of these situations are entirely preventable, and some of them relate with maintenance in the spray booth, a problem called outside in Chapter 10 in the NFPA 33: Standard for Spray Application Using Flammable or Combustible Materials. The section covers general maintenance requirements, elimination of combustible deposits, maintaining high-pressure hoses, waste containers, clothing and cleaning operations amongst other very good information.
When spray booths and finishing equipment are installed, they meet the criteria to get a quality job the very first time through. It’s up to the store to help keep the system clean to ensure that it meets that perfect, first-time performance each time. The system should enable: proper airflow to obtain overspray to the filters instead of on the booth floor, and proper filtration to keep contaminants from the air but also to avoid overspray buildup on the fan or perhaps in the exhaust duct.
For excellent prevention standards, keep Car Body Spray Booths, alter the booth filters regularly, look into the fan and stack for buildup, guard against static electricity and browse the NFPA 33.
Paint Curing or Drying Ovens – Infrared and convection ovens employed for paint curing or drying are another obvious fire hazard within the shop. Again, the best advice is always to always keep the location neat and provide adequate intake air. Remove combustible deposits, as well as eliminate the chance of spontaneous combustion, ensure you hold the correct exhaust volume and purge time. Keep solvent load within the oven below the “Lower Flammability Level,” and purge the oven before startup.
Exactly the same considerations for airborne contaminants should be placed on oven maintenance. Filtered recirculating air or filtered air seals could be critical, and both should be thought about.
Airflow for ovens needs to have sufficient exhaust to evacuate solvent vapors and smoke. Also, analyze product conveyance and design the airflow of the oven to reduce stirring or tracking in dirt. Intake and mkmozc filters are available in many temperature ranges to fit any process.
Ovens, when used for what they are created are for, really are a safe operation as most solvents are evaporated along with other airborne contaminants and combustible deposits shouldn’t be present. It’s really dangerous each time a convection oven is used for other means, like to evaporate solvents by the drum-load, harden booth filters or ‘treat’ other waste deposits.
