What Is The Requirement of Compressive Strength of Cold Storage Board Insulation Material for Cold Storage Board?

Compressive Strength Requirements for Cold Storage Panel Insulation Effective insulation is an important aspect of the floor in any cold storage facility. It helps maintain the correct internal temperature and reduces energy usage. In cold storage, the usual reversal of heat and water flow from inside to outside needs to be considered. Unlike traditional building structures, heat diffuses through the floor and shell, flowing from the moist soil and external environment to the colder, drier interior of the cold storage area.

In addition to the important factors of thermal efficiency and moisture resistance, cold storage panels need to be insulated with adequate compressive strength properties. It must be able to withstand the loads of other flooring materials, as well as the dynamic and static weight of goods and human activities stored in the cold storage facility.

Evaluation of the compressive properties of cold storage panels By measuring the compressive behaviour of a material, such as an insulating material, its ability to resist the above loads can be assessed and determined. The test method for insulating materials consists of placing a sample between two plates of a test apparatus and applying varying degrees of force. Depending on the test method and criteria, the compressive behaviour of an insulating material can vary.

In one case, it can refer to compressing an insulator by 10% of its thickness, resulting in a relative deformation relative to the original sample thickness. This is where the insulating material can be described as failing before 10% compression.

The importance of the compressive strength of cold storage panels Insulation will never be used in a situation where it may be compressed by 10 per cent. The consequences of this mass movement are more than any cold storage panel material can withstand. Evaluating the compressive properties of the floor and specifying the correct insulation is critical to the safe and proper operation of the cold storage structure.

Insulated concrete slabs are a common requirement for cold storage facilities. Therefore, cold storage slab insulation must be able to withstand heavy loads. This includes the structural loads of the floor itself, as well as the stored goods and the dynamic loads of pedestrians and heavy vehicles travelling over the floor.

Compression creep is another important factor in specifying cold storage panel insulation. Long-term loading produces progressive compression that affects different materials in different ways. Therefore, the long-term effects of loading require a different measurement - compression creep. The static weight of stored goods is more likely to be the cause of compression creep.

However, many insulation manufacturers do not test for compression creep because it requires a test cycle of 122 to 608 days, depending on the analogue year - 10, 25 or 50 years. Some manufacturers claim that compression creep is ‘compression strength at 2% compression’ or similar, as the total compression proved is usually around 2%.

Compressive Strength Characteristics of Cold Storage Boards Cold storage boards offer the greatest range of compressive strengths and are one of the few insulation products for which manufacturers have invested the time to test and claim compression creep. The uniform distribution of closed cells in cold storage panels gives it excellent compressive strength properties. This makes it a reliable and long-lasting solution for cold storage panels that must withstand heavy loads.
