Abstract

The invention belongs to the technical field of needled felts, and particularly relates to a high-performance PTFE (polytetrafluoroethylene) coated needled felt and a preparation method thereof. Jacks, a socket heat conduction post, a fixed heat conduction plate, a sleeving heat conduction plate, a magnetic unit and a projecting post unit are arranged among a PTFE net base layer, a heat insulationcotton layer and a PTFE coated layer, so that the PTFE coated needled felt is effectively used. The needled felt has the advantages that a five-layer structure is high in stability, a sleeving heat conduction plate fixing structure is reasonable and effective, high in fixing strength and good in heat dissipation effect, the needled felt is good in overall use effect, and the filtering dust removal capacity of the PTFE coated needled felt is finally improved.

Description

technical field [0001] The invention belongs to the technical field of needle-punched felts, in particular to high-performance PTFE-coated needle-punched felts and a preparation method thereof. Background technique [0002] PTFE needle-punched felt is a filter material with superior performance. It mainly includes a PTFE grid base layer and a PTFE fiber coating layer set on it. This two-layer structure can achieve effective dust filtration and interception effects. On the other hand, the existing PTFE needle-punched felts generally add heat-insulating cotton layers and / or iron wire reinforcement layers to cope with various complex filtration environments, but the above-mentioned multi-layered needle-punched felts have insufficient structural strength and are prone to delamination Scattering, and poor heat dissipation, and high-temperature use environment will reduce the dust removal ability of PTFE fibers, so the market urgently needs a PTFE-coated needle-punched felt with a...
