Humidity can be the "natural enemy" of corrugated boxes. Because the cardboard pressure line bursts when the autumn is dry, and the carton becomes soft when the spring rain is flooded. This dramatically affects the corrugated packaging's loss, quality, and service life. As the opponent of the "natural enemy" of the carton, the large industrial HVLS ceiling fan helps the packaging factory "prescribe the right medicine." After rationally planning the large industrial HVLS ceiling fan installation plan, the packaging factory will control the ambient humidity and not be afraid of natural enemies anymore.
The worst thing about corrugated boxes is that they get wet and soaked in water. If the corrugated containers get wet, the paper will become soft and not meet the requirements. Once the cardboard is soaked in water, it will open the glue and be treated as waste paper. According to scientific research, when the ambient temperature is constant at 23°C, with the increase of ambient humidity, the moisture content of corrugated boxes is linearly positively correlated; With the rise of environmental humidity and moisture content, the compressive strength and the adhesive strength and FCL compressive strength gradually decreased, which mainly because the cellulose in the corrugated cardboard gradually became loose after absorbing moisture; With the increase of the moisture content in the cardboard, the bursting strength and puncture strength showed a rise first and then decreased with a peak value curve changes. This indicates that too dry and too wet will significantly impact the anti-burst ability of the carton.
From this, it can be seen that controlling the environmental humidity is very important for corrugated boxes. And it is necessary to rely on large industrial HVLS ceiling fans to help the packaging factory do an excellent ventilation and humidity control job. The industrial large-scale HVLS ceiling fan discharges the moisture and humidity in the factory through the doors and windows and brings fresh air into the room to keep the packaging factory dry and clean and the air is fresh. In rainy weather, the GX industrial large HVLS ceiling fan rotates slowly through the fan blades to drive the airflow in the workshop. The large air circulation brought by the massive air volume accelerates the air circulation and accelerates the air exchange efficiency inside and outside the workshop. In hot and dry weather, through the continuous operation of the large-diameter HVLS ceiling fan, the large industrial HVLS ceiling fan moves the air in the sultry environment. It discharges the hot air to the outside, which can appropriately reduce the overall ambient temperature of the factory building and prevent the air from being too dry and hot to affect the top of the carton—breaking ability.
In addition, GX HVLS large industrial ceiling fans can help employees in packaging plants improve their comfortable working environment. Because the giant HVLS ceiling fan absorbs heat through the evaporation of sweat moisture, workers can feel the temperature drop by 5-6°C in the workshop where the huge HVLS ceiling fan is installed. With the slow rotation of a large fan with a diameter of 7.3 meters, a substantial natural air volume spreads throughout the entire factory building. On average, one set most enormous 24ft diameter fan could cover more than 1000 square meters. This could replace 50 sets 0.75m diameter small ceiling fans. Apart from the hot season, as the GX HVLS ceiling fan has a reverse function, GX HVLS industrial ceiling fan could also play a considerable role during cold winter. GX HVLS industrial ceiling fan could mix the hot upper air with the below cold air to increase the ambient temperature throughout the packaging plant. The industrial HVLS ceiling fan can evaporate water to reduce condensation if used with an eco-friendly air conditioner. On the one hand, this saves the electricity cost of the packaging plant, and on the other hand, the corrugated box reduces the possibility of moisture.
As a paper packaging product, the impact of humidity on the development is compassionate. The control of ambient humidity by GX large industrial large HVLS ceiling fans can reduce the damage of cartons and ensure the quality of cartons. Corrugated boxes will be affected by environmental moisture in the production and circulation process, requiring packaging factory manufacturers to reasonably control the environmental humidity in these links. Enterprises using corrugated boxes should also consider the ecological humidity of the destination of the goods, especially if they need to be transported from dry areas to areas with high moisture, such as from northern China to the south with high humidity. Or, when exporting by sea, kindly pay attention to using good ventilation and dehumidification equipment to ensure the safe storage of carton goods.
