摘要:为了提高金属针布的使用寿命,开发高耐磨金属针布齿条,介绍目前国内对金属针布磨损机理研究以及研究需采用的试验方法和几种不同材质新型金属针布齿条的微观形貌;通过对涡流纺和静电纺用分梳辊金属针布齿条进行电镜微观形貌观察和磨损量测定,推断磨损机理;根据耐磨度、材质、金相组织和表面粗糙度等,分析影响金属针布磨损的因素。提出:在常规纺纱中,金属针布的磨损是以软磨料反复冲击疲劳和氧化腐蚀相结合为主的磨损,但也存在硬磨料犁耕磨损;在静电纺纱中,分梳辊金属针布的磨损为电化学腐蚀;在化纤纺中,除软磨料冲击疲劳对金属针布的磨损外,还存在化学腐蚀磨损;影响金属针布磨损的主要因素有齿条表面氧化皮、表面粗糙度、钢材成份、金相组织、梳棉机高速高产以及小隔距、强分梳纺纱技术和高温高湿的纺纱环境等,为研究金属针布齿条选材、制造工艺和表面处理,延长金属针布使用寿命提供依据。

Abstract:To prolong the service life of MCC,and to develop high wear-resistant MCC wires,introduction is done to the current domestic study of MCC wear mechanism and the research on wear test and microstructure of several different materials of new metal clothing.Through electron microscopic morphology observation of combing roller MCC wires and wear,determination is done to vortex spinning and electro-spinning,and the wear mechanism is extracted.Factors of wear resistance,texture,microstructure and surface roughness are surposed to be the influence factors of wear of MCC.It is pointed out that in the conventional spinning,wear of MCC results mainly from soft abrasive repeated impact fatigue and oxidation corrosion.Secondly from plough wear while in electrostatic spinning,wear of MCC on combing roller mainly results from electrochemical corrosion;and in chemical fiber spinning,both of the above-said factors are included,which illustrates that the main factors influencing wear of MCC include oxidation rack surface skin,surface roughness,steel materials,metallographic structure,high yield and high speed carding machine with small gauge,strong carding spinning technology and spinning environment of high humidity,providing information for research of material selection, manufacturing and surface treatment of MCC and prolong the service life of MCC.
Key Words:MCC;wire;wear mechanism;carding roller;abrasive wear;impact fatigue wear;oxidation corrosion; electrochemical corrosion;surface roughness;metallographic structure
