NEMA外壳的最佳材料是什么?

对于不同的用例,有各种各样的NEMA外壳。请查看以下NEMA附件的类型。类型1:基本,室内封闭,防止灰尘和落尘。2型:室内围护结构,防尘、防落尘、防水溅。类型3:室内和室外围护,防止风吹灰尘和落尘,防止水(雨,雨夹雪,雪和冰形成的影响)。类型4:室内和室外围护,防止风吹灰尘和落尘,防止水(雨,雨夹雪,雪,泼水和软管直接水)和冰的形成。类型5:室内和室外围护,防止掉落的灰尘,沉降空气中的灰尘,棉绒,纤维和飞行的碎片。也可以防止水(雨,雨夹雪,雪,溅水和软管导向的水)和冰形成的影响。类型6:室内和室外围护,防止掉落的灰尘。还可以防止高速和大量的水(水软管,和在有限深度的潜水期间的水进入)和冰形成的影响。 Type 12: Indoor enclosure, protects against falling dirt, settling airborne dust, lint, fibers. Also protects against water (dripping and light splashing). Type 13: Indoor enclosure, protects against falling dirt, settling airborne dust, lint, fibers and flying debris. Also protects against water (dripping and light splashing). Some protection against spraying/splashing/seepage of oil and coolants. Materials Types Recommended for each of these NEMA Scenarios and use-cases Type:2: Microcellular Open Cell foams, or Closed Cell foams, Closed Cell sponges Type 3: Closed cell foams, or Closed Cell sponges Type 4: Closed cell foams, or Closed Cell sponges Type 5: Closed cell foams, or Closed Cell sponges Type 6: Closed cell foams, Closed Cell sponges, low-to-medium Duro elastomers/rubber Type 12: Microcellular Open Cell foams, or Closed Cell foams, Closed Cell sponges Type:13: Closed Cell sponge with the right corresponding chemical compatibility
