预氧纤维毡
作者:admin  更新时间:2019-07-23
产品简介:预氧纤维毡是将聚丙烯腈基纤维进行预氧,卷曲,截断,针刺所得,碳化后为预氧纤维碳毡,石墨化后为预氧纤维石墨毡。相比PAN基石墨毡具有密度低,柔软度好,对皮肤的刺激性低等优点。Pre-oxidized fiber felt is obtained by pre-oxygenation, crimping, cutting and needling of polyacrylonitrile-based fibers. , it is called pre-oxidized fiber fiber carbon felt after carbonization,  it is called pre-oxidized fiber fiber graphite felt after graphitization,. Compared with PAN-based graphite felt, it has the advantages of low density, good softness and low irritation to skin.
