Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.
[0045] All along, the main material of the packaging base of the refrigerator is EPS foam, but EPS material is foamed polystyrene. EPS material has the following shortcomings:
[0046] 1. Poor heat resistance: the maximum bearing temperature of EPS is only 70℃, and it is easy to soften and deform in a high-temperature environment, which limits its application in high-temperature scenarios.
[0047] 2. Low strength: EPS is relatively soft, and its compression strength and impact resistance are weak, so it is easy to be damaged in applications that need to bear large pressure.
[0048] 3. Environmental protection problem: EPS is difficult to degrade naturally, stays in the environment for a long time, and is easy to cause white pollution. When incinerated, it will also produce harmful gases and pollute the air.
