Polyurethane rigid foam waterproof and thermal insulation integrated panels (referred to as 'polyurethane insulation panels') are widely used in building exterior walls, roofs and other projects due to their excellent thermal insulation and waterproof properties. In order to ensure stable performance and extend service life, please pay attention to the following matters when storing:
1. Environmental condition control
temperature range
Suitable temperature: 5℃~35℃, avoid extreme high or low temperatures.
High temperatures (such as summer exposure) may cause polyurethane foam to soften, deform, and even release harmful gases.
Low temperatures (such as winter cold) may embrittle materials and increase the risk of handling damage.
Handling extreme situations: If it needs to be stored in a high or low temperature environment for a short period of time, it needs to be covered with awnings and insulation materials, and moved to a suitable environment as soon as possible.
Humidity control
Relative humidity: ≤60%, to prevent the material from absorbing moisture.
After polyurethane rigid foam absorbs moisture, it can easily lead to a decrease in thermal insulation performance, condensation on the surface, and even the growth of mold.
Moisture-proof measures:
Store in a dry and ventilated warehouse, with moisture-proof mats (such as plastic film, wooden pallets) on the floor.
Avoid direct contact with the floor or wall to prevent condensation water from penetrating.
Dehumidifiers or desiccants can be equipped in rainy seasons or humid areas.
Ventilation requirements
Maintain air circulation in the warehouse to avoid humidity accumulation or odor residue caused by a closed environment.
Regularly check whether the vents are clear to prevent them from being blocked by debris.
2. Stacking and handling specifications
Stacking method
Stack flat:
The board should face upward, and the layers should be separated by flat wooden boards or hard materials to avoid deformation caused by direct extrusion.
The stacking height should not exceed 3 meters to prevent damage to the underlying panels due to excessive pressure.
Vertical storage:
If space is limited and it needs to be placed vertically, special brackets must be used to secure the board to ensure it is vertical and stable.
When standing, leave a 5-10cm gap between the boards to prevent them from squeezing each other.
Moving requirements
Handle with care: Avoid violent collisions and falls, and prevent edge damage to the board or damage to the internal structure.
Use special tools: For example, when transporting with a forklift, the width of the fork needs to be adjusted to fit the plate, and soft material must be used for protection.
Avoid dragging: It is forbidden to drag the board on the ground to prevent surface scratches or structural damage.
3. Protective measures
Sun and rain protection
When stored outdoors, it needs to be covered with waterproof canvas or an awning to prevent it from being wetted by rain or direct sunlight.
The covering needs to be firmly fixed to prevent the panels from being overturned by strong winds and exposing the panels.
Anti-pollution
Keep away from chemicals, oil, acids and alkalis and other corrosive substances to prevent surface contamination or performance degradation.
If you accidentally come into contact with contaminants, rinse with clean water and dry immediately.
Anti-Pests and Rats
Regularly inspect the warehouse and seal gaps to prevent insects and mice from chewing on the edges of the panels or internal structures.
You can place insect repellent or set up rodent-proof boards.
4. Regular inspection and records
Appearance inspection
Check every month whether the surface of the board is flat, without cracks or deformation, and whether the edges are intact.
If any damage or abnormality is found, it must be isolated and dealt with promptly to avoid the problem from expanding.
Performance sampling
Boards are randomly selected every quarter for performance testing (such as thermal conductivity, water absorption) to ensure compliance with standard requirements.
Record test data and create and save files to provide reference for subsequent use.
Inventory management
Store according to specifications and batches, and follow the 'first in, first out' principle to avoid performance degradation caused by long-term backlog.
When the inventory is large, the plates need to be turned over regularly to prevent the bottom from being deformed due to pressure.
5. Special scene processing
long term storage
If it needs to be stored for more than 6 months, the plates need to be checked and turned regularly to prevent deformation caused by long-term pressure.
Consider covering the surface of the board with a protective film to reduce dust adhesion and UV aging.
Transportation transfer
Transport vehicles must be clean and dry, and avoid mixing with sharp objects.
Secure the panels to prevent them from sliding and cover them with tarps for protection.
