Dripping Inside Container Houses
Dripping inside container houses can be caused by issues with rainproof performance, temperature differential condensation, external moisture infiltration, the inherent humidity of the cargo, high air humidity, or improper insulation layer design, requiring targeted solutions.
Rainproof Performance Issues: Defects in the waterproof layer, drainage system, sealing performance, or water resistance of the disassembly and assembly structure of foldable container houses, or poor quality of the container itself and inadequate sealing at connection points, can all lead to rainwater infiltration. Solutions include regularly inspecting and maintaining the waterproof layer and drainage system to ensure their proper operation; adding waterproof membranes or coatings during the design and construction phases to enhance the waterproof performance of the roof and walls; using sealing strips, sealants, and other materials at connection points to improve sealing; and if leakage has already occurred, identifying the cause and contacting the responsible party for repairs.
Temperature Differential Condensation: When there is a significant temperature difference between the inside and outside of the container, water vapor in the air can condense into water droplets on cooler surfaces, such as when there is a large temperature difference between day and night or when air conditioning causes the floor temperature to drop below the dew point. Solutions involve improving insulation performance by adding insulation layers or using thermal insulation materials to reduce the temperature difference between the inside and outside, thereby lowering the risk of condensation.
External Moisture Infiltration: Unreasonable design or poor sealing of ventilation holes in the container, or direct placement on unhardened mud or grass, where ground moisture can seep upward through capillary action, can exacerbate moisture accumulation inside the container. Solutions include checking the sealing of ventilation holes to ensure they are reasonably designed and leak-free; avoiding direct contact between the container and damp ground, and laying moisture-proof mats or hardening the ground if necessary.
Inherent Humidity of Cargo: Cargo with a high moisture content (e.g., wood with a moisture content of 8%-25%) can release water vapor, increasing the humidity inside the container. Solutions involve prioritizing cargo with lower humidity or drying high-humidity cargo before storage.
High Air Humidity: In areas with high temperatures and humidity, the air contains a large amount of water vapor, providing ample 'raw materials' for condensation. Solutions involve using dehumidifiers or air conditioners inside the container to actively reduce air humidity.
Improper Insulation Layer Design: Missing or insufficiently thick ground insulation layers, or the use of moisture-absorbing materials, can intensify heat exchange, causing the floor temperature to drop below the dew point and triggering moisture return. Solutions involve redesigning the insulation layer to ensure sufficient thickness and the use of materials with good thermal insulation and low moisture absorption.
