Within the finishing industry, there is a real connection between safety and quality-especially when it comes to spray booths, which can run the risk of causing fire if not properly maintained. Equipment for dust collection is strategically designed to meet specific needs in terms of performance, like airflow velocity; fan, filter and burner capacity; and safety pertaining to fire prevention and operator wellbeing.

However, once the manufacturer ships the gear, installation, operator training and maintenance become the responsibility of the finisher. Therefore, it is recommended to give both Hot Sale Furniture Spray Booth and associated processes a comprehensive review for fire safety hazards and other incidents that may occur.

Dust Collection – The two main sides of dust collection: quality and safety. A high quality finish will be the direct result of adequate removing of airborne particles that could contaminate finished surfaces. This contamination causes rejects or rework of item that leads to lost profits.

It’s not only surface finish that particle build-up can impact, though. Or even cleaned, particles can migrate to places that operators may not have proper breathing protection, and fire gets to be a real hazard. Sufficient airflow is essential.

The very best causes of fire in dust collection systems include: static electricity discharge, exothermic reaction because of chemical reaction of collected dust,

cutting or welding too near the area.

The bottom line is to collect the dust using a well-designed dust collection system that contains a smart layout and balanced air replacement. As suggested through the National Fire Prevention Association (NFPA): “Air flow needs to be carefully considered.” Criteria for dust collection processes usually include air velocity within the booth of 125 to 150 FPM. If properly filtered, this air could be recycled into the facility. Fresh air dilution ratios for any facility also have to consider heat, off-gases, and odors from ancillary processes including sanding or grinding.

Furthermore, doors or pressurized plenums could be used to contain dust. An investment in containment is going to be reflected in less money spent on cleaning and correcting finish rejects.

Spray Finishing Systems and Booths – Big Inflatable Spray Booth have a number of their particular specific requirements for safety and quality. First, sufficient and laminar airflow is necessary so that the exhaust can capture overspray and pull it to the filtration systems, which can be either a dry filter or even a water wash. To get rid of particulate from your air, the proper filter media or chamber is essential. Then, the new air supply needs to be not just clean, but additionally on the correct temperature. More sophisticated coatings could also require humidity control. Not to mention, all equipment must be properly grounded.

The very best fire prevention may begin with understanding of what can result in a fire in a spray booth. In a conventional system, leading causes of fire include:

using spark-producing equipment such as cutting, welding or grinding close to the spray area; friction, typically brought on by 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 in the spray area, failure to completely discharge equipment before cleaning, pinhole leaks inside the paint tubing to the spray gun, other causes much like conventional systems including smoking, cutting and welding.

Many of these situations are entirely preventable, and many of them relate to maintenance within the spray booth, a concern called in Chapter 10 of the NFPA 33: Standard for Spray Application Using Flammable or Combustible Materials. The section covers general maintenance requirements, removing of combustible deposits, maintaining high-pressure hoses, waste containers, clothing and cleaning operations amongst other excellent information.

When spray booths and finishing equipment are installed, they fulfill the criteria for a quality job the first time through. It’s up to the store to help keep the device clean so that it meets that perfect, first-time performance each and every time. The device should permit: proper airflow to obtain overspray to the filters rather than on the booth floor, and proper filtration to help keep contaminants out of the air but in addition to avoid overspray buildup on the fan or perhaps in the exhaust duct.

For excellent prevention standards, keep Furniture Painting Spray Booth, change the booth filters regularly, check the fan and stack for buildup, guard against static electricity and read the NFPA 33.

Paint Curing or Drying Ovens – Infrared and convection ovens utilized for paint curing or drying are another obvious fire hazard inside the shop. Again, the best advice is always to keep the location clean and provide adequate intake air. Remove combustible deposits, as well as eliminate the risk 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 needs to be put on oven maintenance. Filtered recirculating air or filtered air seals may be critical, and both should be considered.

Airflow for ovens must have sufficient exhaust to evacuate solvent vapors and smoke. Also, analyze product conveyance and design the airflow from the oven to minimize stirring or tracking in dirt. Intake and mkmozc filters are available in many temperature ranges to match any process.

Ovens, when utilized for what they are designed are for, certainly are a safe operation since many solvents are evaporated along with other airborne contaminants and combustible deposits shouldn’t be present. It’s really dangerous whenever a convection oven is used for other means, including to evaporate solvents from the drum-load, harden booth filters or ‘treat’ other waste deposits.
