Home appliance type combined polyether products are mainly used for heat insulation and heat preservation of refrigerators, freezers, and insulated boxes, providing good heat preservation effect. During the production process, polyurethane foam is poured between the outer shell and inner liner of the box to form a continuous insulation layer. Its main function is to reduce the heat exchange between the inside and outside of the refrigerator and freezer. By limiting the conduction, convection, and radiation of heat, the refrigerator maintains a low-temperature environment, thereby reducing the energy consumption of the refrigeration system and extending the shelf life of food.
Performance and Uses:
1. Excellent insulation performance: It can effectively reduce the energy consumption of refrigerators and freezers. Under the same usage conditions, compared with other insulation materials (such as glass wool), refrigerators and freezers with polyurethane insulation can save 30% - 50% energy consumption. This can save users a lot of electricity costs for long-term use of home appliances.
2. Good dimensional stability: The polyurethane insulation layer can maintain its shape and size during the use of refrigerators and freezers. It will not shrink, expand, or deform due to temperature changes or long-term use, ensuring the structural integrity and durability of the insulation performance of the refrigerator and freezer.
3. Strong adhesion: It can adhere well to the inner and outer shells of refrigerators and freezers. This good adhesion can prevent gaps or shedding of the insulation layer, ensuring the continuity and sealing of the insulation layer, and further improving the insulation effect.
4. Good water resistance: Due to its closed-cell structure, the polyurethane insulation layer can effectively prevent water from entering. This is very important for appliances such as refrigerators and freezers that often come into contact with water (such as water produced during the defrosting process), and can prevent the insulation layer from being damaged by water absorption, extending the service life of the insulation layer.
