The ventilation of acid-base corrosion workshops should fully consider the type and concentration of corrosive gases, and make effective and targeted heavy-duty anti-corrosion schemes for the roof natural ventilator according to the characteristics of the corrosive gases. For general acid-base corrosion workshops, FRP panels should be considered for the panels of natural ventilators. Since FRP is a glass fiber polyester panel, its glass fibers are wrapped by unsaturated resin, so it has good anti-corrosion performance. The profile frame of the natural ventilator can be considered to use a reasonable anti-corrosion layer to isolate the corrosive gas. According to the dimensions of the workshop, equipment layout, and production process characteristics, Mcwell can design the natural ventilator, according to client's requirement.
