Use a moisture-proof layer together with the insulation board.<\/span><\/span><\/h3>\nUse a highly effective moisture barrier. This layer of insulation is only located on the hot side of the insulation board. If the insulation layer is placed on the cold side of the insulation board, the risk of moisture condensation in the insulation increases many times. Improve the moisture coefficient of insulation materials: Insulation materials can be mixed with binder resins or binder bitumen to increase moisture diffusion resistance.<\/span><\/p>\nThe amount of moisture diffused from the air or the hot surface of the insulation will decrease rapidly. Meanwhile, the amount of moisture diffusing from the wall of insulation into the cold room decreases at a smaller rate. Cold storage requires that the amount of moisture diffused from the wall of insulation into the cold room is greater than or equal to the amount of moisture diffused from the high-temperature environment into the wall of the insulation. This will prevent moisture from condensing in the wall of the insulation.<\/span><\/p>\n<\/span>2. Create positive pressure in cold storage.<\/span><\/span><\/h3>\nThereby, it is possible to create an air flow through the insulation wall in the opposite direction to the drop in water vapor pressure.<\/span><\/p>\nArtificial effect on the partial pressure of water vapor on the cold surface of the wall of insulation.<\/span><\/p>\nDue to the phenomenon of condensation of moisture in the wall of the insulation board of the cold storage, it is necessary to have a layer of moisture to increase the moisture resistance of the insulation board.<\/span><\/p>\n
Methods of preventing moisture contamination for cold storage insulation panels<\/span><\/em><\/figcaption><\/figure>\n<\/span>3. Using moisture-insulating materials in cold storage<\/span><\/strong><\/span><\/h3>\nFor a long time, people have used moisture insulation with relatively high efficiency. However, the insulation layer is only arranged on the hot side. If the insulation layer is arranged on the cold side, the risk of condensation of insulation moisture increases many times.<\/span><\/p>\nOnly the hot side of the wall should be insulated. In case the cold side is impervious to moisture (refrigeration pipelines, low pressure tanks, liquid separators), the coating of moisture insulation gradually accumulates over a long time in the insulation of pipes and equipment.<\/span><\/p>\n<\/span>4. Increase the moisture diffusion impedance coefficient of the material<\/span><\/strong><\/span><\/h3>\nCold storage moisture-insulating materials can be mixed with binder resins or binder bitumen to increase moisture diffusion impedance. The amount of moisture diffused in the air is increased the moisture diffusion impedance. The amount of moisture diffusing from the air or the high temperature surface of the insulation will decrease rapidly while the amount of moisture diffusing from the insulation wall into the cold storage decreases at a smaller rate. It is required that the amount of moisture diffused from the wall into the cold storage is greater than or equal to the amount of moisture diffused from the hot environment into the wall. This way, there will be no more moisture condensing in the wall.<\/span><\/p>\n<\/span>High efficiency cold storage panel preservation method<\/span><\/span><\/h1>\nSo besides using it properly, the most important thing is to know how to store the product well. Also on this occasion, MCW will send you methods to preserve high efficiency cold storage panels.” Now let’s find out how to do it!<\/span><\/p>\n<\/span>1. Do not expose cold storage pu panels to high temperatures<\/span><\/span><\/h3>\nHigh temperatures above 40 degrees Celsius directly and continuously affect the cold storage pu panel. When the product can be stretched, changed in size and quality when we leave the material horizontally in places with too high temperature conditions. To\u00a0 <\/span>preserve the cold storage pu panel<\/span><\/strong> \u00a0, the simplest way is to put it under the roof with a temperature of 20 – 30 degrees Celsius is the most suitable.<\/span><\/p>\n<\/span>2. Isolate the cold storage pu panel from the ground<\/span><\/span><\/h3>\nThe ground has high humidity or has a very fast growth of microorganisms, this is a favorable environment for bacteria to easily adhere to the surface of the cold storage panel. To avoid this, we should put all products on wooden shelves, pallets or wooden beams.<\/span><\/p>\n<\/span>3. Prohibit placing large objects on the panel surface<\/span><\/span><\/h3>\nEach cleanroom pu panel itself can only withstand a weight of 5-10kg. If the weight exceeds the allowable level, it will break the link between the steel fibers in the outer layer of the PU surface. Therefore, properly preserving the cleanroom panel is to limit placing heavy objects.<\/span><\/p>\n<\/span>4. Isolate panel material from low pressure area<\/span><\/span><\/h3>\nPressure too low will easily affect the quality and chemical properties of the product against fire and effective insulation. Therefore, according to experts in the field of insulation, we should not let the panel have low pressure.<\/span><\/p>\n
