Best Materials for Cold Storage Flooring
Cold storage units are climate-controlled facilities used for storing food, dairy products, meat, seafood, and other perishable items. Currently, China ranks third globally in cold storage capacity, behind India and the United States.
Cold storage units are categorized into low-temperature, medium-temperature, high-temperature, quick-freeze, and controlled atmosphere types. The primary market is low-temperature storage, accounting for 72%, primarily used for food storage at -18 to -25°C, which is ideal for preserving meat and vaccines. The unique environment of cold storage units demands high-quality flooring materials that can withstand prolonged low temperatures and endure the impact and pressure of forklifts during loading and unloading. Therefore, the materials must exhibit excellent low-temperature resistance and impact durability.
Common Solutions for Cold Storage Flooring and Their Issues
Option 1: Steel shot applied with a sealing hardener to create a dense surface, preventing water infiltration.
Option 2: Water-based polyurethane mortar, which is effective in preventing freeze-cracking and water seepage.
Challenges:
- As a rigid system, it is less effective against cracking. While the flooring generally performs well, localized cracking can allow ice water to seep in, causing expansion and concrete damage.
- Low-temperature conditions slow the chemical reaction, necessitating shutdowns for maintenance and increasing costs.
- Mechanical properties degrade in low temperatures, resulting in a reduced lifespan of the flooring.
For cold storage flooring solutions, polyaspartic polyurea (Feiyang) offers significant advantages. It is suitable for both new flooring projects and the renovation of old, damaged floors:
- Polyaspartic polyurea exhibits excellent low-temperature reactivity and durability, allowing maintenance without shutdowns, thereby reducing costs and providing high cost-effectiveness.
- Its elastic system features high strength (≥10MPa) and high elongation (≥200%), which makes it wear-resistant and able to bear heavy loads.
- It maintains crack resistance at low temperatures, with a dense and waterproof paint film that prevents water infiltration and consequent concrete expansion and cracking.
- Aesthetically pleasing, inert material, resistant to bacteria and dirt.
