PU material spraying on the bottom of the expandable container: insulation solution in low temperature environment like Russia,Canada

    With the continuous development of global trade, more and more products need to be exported to areas with extreme climatic conditions, such as Russia and Canada. The extremely low winter temperatures in these areas pose a severe challenge to the insulation performance of goods. In order to ensure that the goods are not affected by low temperatures during transportation and maintain their quality and integrity, it is particularly important to take effective insulation measures.

    Against this background, spraying PU (polyurethane) material on the bottom of the expansion box has become an effective insulation solution. PU materials are widely used in many fields such as construction, automobiles, and furniture due to their excellent insulation performance, good mechanical strength, and chemical corrosion resistance. Applying it to the bottom of the expansion box can form a solid insulation layer in a low temperature environment, effectively isolating the impact of low temperature on the goods in the box.

    The process of spraying PU material is relatively simple. First, the bottom of the expansion box needs to be cleaned to ensure that there are no impurities such as oil, dust, etc. on the surface to ensure that the PU material can be evenly attached. Then, the PU material is evenly sprayed on the bottom surface of the box by professional spraying equipment. After the spraying is completed, the PU material will solidify within a certain period of time to form a dense insulation layer.

    This insulation layer can not only effectively isolate the low temperature outside, but also prevent the goods in the box from generating condensation water due to excessive temperature difference to a certain extent, thereby preventing the goods from getting damp and deteriorating. In addition, PU material also has good impact resistance and wear resistance, which can protect the bottom of the expansion box from wear and impact during transportation and extend the service life of the box.

    In short, spraying PU material on the bottom of the expansion box is an economical and effective insulation measure, especially suitable for the transportation of goods exported to low-temperature areas such as Russia and Canada. It can not only ensure the quality and integrity of the goods during transportation, but also improve the market competitiveness of the goods and bring greater economic benefits to the enterprise. With the continuous advancement of technology and the continuous promotion of application, the insulation application of PU materials in low-temperature environments will become more and more extensive.
