Notes
1. Packaging requirements: moisture-proof and shock-proof packaging is used. It is recommended to use wooden frames or pallets to fix them to avoid collision and breakage during transportation; the outer packaging must be clearly marked with "fragile" and "upward" signs, and product specifications and batch information must be attached.
2. Transportation specifications: During transportation, the goods must be stably fixed to avoid severe bumps or high-altitude falls; it is prohibited to mix with corrosive chemicals, and the whole process must be protected from rain, moisture, and exposure.
3. Storage conditions: It should be stored in a dry and ventilated indoor environment to avoid direct contact with the ground. It is recommended to use pallets to raise it; during long-term storage, the integrity of the packaging must be checked regularly, and the stacking height should not exceed 2 layers to prevent the bottom from being compressed and damaged.
4. Instructions for use: Before installation, check whether the surface of the heat storage body is intact and free of cracks. It is strictly forbidden to use damaged products; pre-drying treatment must be carried out according to process requirements for the first use to avoid thermal stress cracking caused by rapid cooling and heating; flue gas temperature, composition and pressure difference must be monitored during operation to avoid long-term overheating or overload.
