Study on Wear of Cutter Blades for Cutting Chemical Fibers

  • 摘要: 利用自制小型短纤维切断试验装置模拟涤纶短纤维的切割加工过程,采用台式投影仪测量切断刀刃口的线磨损量,采用扫描电子显微镜观察刃口和刃面的磨损表面形貌,采用傅立叶变换红外-拉曼光谱仪分析刃口磨损表面转移膜的性质,并采用顺磁共振仪分析了纤维切断前后自由基的含量.结果表明:切割涤纶半消光纤维时,高速钢刀片的磨损很快,主要磨损机制为纤维中TiO2粒子的磨粒磨损;硬质合金刀片的磨损缓慢,其磨损主要是由于刃口上高分子转移膜脱落引起的.

     

    Abstract: Wear is the one of cause leading to failure of chemical fiber cutter blades in the process of staple fiber production, production and processing of polyester staple cutting was simulated with a self-made miniature staple cutting equipment. Edge wear of cutter blade were measured using a table projector. Worn surface morphology of the blade edge and side plane were observed using a scanning electron microscope. Property and classification of transfer film on the worn surface were analysed by means of Fourier transform infrared-Raman spectrometer. Content of the free-radical were determined using the paramagnetic resonance method. Result shows that high speed steel cutter blade wear seriously during fiber cutting, its main wear mechanism is abrasion of TiO2 particles in fibers. Cemented carbides cutter blade wear slightly, its main wear mechanism is separation of transferred film.
