钢丝绳一般在五金市场出售,GB8918-2006重要用途钢丝绳
起重设备常用钢丝绳品种如下:
1.磷化涂层钢丝绳(中国专利),钢丝经锰系或锌锰系磷化处理,钢丝表面耐磨性、耐蚀性全面跃升,磷化膜与润滑脂的复合作用,有效抑制微动磨损的发生,彻底解决钢丝绳的磨损问题,疲劳寿命是同结构光面钢丝绳3倍,通过疲劳试验可以验证疲劳寿命(亲自做疲劳试验最具可信性),是光面钢丝绳的升级换代产品,也可替代先镀后拔薄锌层镀锌钢丝绳使用(可通过盐雾试验检验或对比耐蚀能力),使用寿命超长,单位使用成本更低,稳定性更佳。
2.镀锌钢丝绳,包括热镀锌和电镀锌两种,一般而言,热镀锌锌层厚,电镀锌锌层薄
3.不锈钢丝绳,以304或316不锈钢为主,防腐蚀效果非常优秀但是价格昂贵
4.涂塑钢丝绳,碳素钢丝绳基础上,外层涂覆聚乙烯、聚丙烯或尼龙
5.光面钢丝绳,使用寿命短,市场需求剧减,将被磷化涂层钢丝绳全面淘汰。
6.海洋工程系泊用钢丝绳
7.缆索钢丝绳
大气环境中使用的起重机械,优选锰系磷化涂层钢丝绳,重腐蚀环境优选热镀锌—磷化双涂层钢丝绳,海水中优先海工钢丝绳。采购时请注意,在购货发票必须注明钢丝绳名称,如磷化涂层钢丝绳或316不锈钢丝绳,以保护自身合法权益,另外,专利产品一般在钢丝绳外包装上有专利号喷涂标注,质保书应有主要技术指标,如磷化膜种类和膜重,仅供参考
起重机用户需要高质量的钢丝绳,应该就是使用寿命长且质量高度稳定可靠的钢丝绳。
大气环境中使用的钢丝绳,造成钢丝绳失效的主要原因是微动疲劳,目前,世界钢丝绳领域第一次针对微动疲劳采取防治措施是专利技术生产的磷化涂层钢丝绳,制绳钢丝经过锰系磷化或锌锰系处理,钢丝表面耐磨性耐蚀性全面提升,不易磨损和不易腐蚀使疲劳寿命大幅度提升,疲劳寿命是同结构光面钢丝绳的三倍,最高的试验值对比已经达到惊人的四倍,可通过疲劳试验进行验证,如果自己有疲劳寿命能力就自己做对比试验,这样的试验结果最可信,钢丝绳使用寿命与疲劳寿命成正比关系,疲劳寿命长则使用寿命同比例延长,使用成本更低,稳定性更佳,磷化涂层钢丝绳是专利技术生产的,因为供不应求目前比较难买,需要多询问几个钢丝绳生产商,采购时请注意,在购货发票必须注明钢丝绳名称,如磷化涂层钢丝绳或316不锈钢丝绳,防范不法企业侵害自身合法权益,另外,专利产品一般在钢丝绳外包装上有专利号喷涂标注,质保书应有主要技术指标,如磷化膜种类和膜重(磷化膜膜重大小、耐磨性、耐蚀性等对钢丝绳使用寿命有重要影响),仅供参考
国内生产钢丝绳品种如下: 1.磷化涂层钢丝绳(中国专利),钢丝经锰系、锌锰系磷化处理,钢丝的耐磨性、耐蚀性全面跃升,不易磨损、不易锈蚀使钢丝绳疲劳寿命超大幅度提高,疲劳寿命是同结构光面钢丝绳3倍(试验室可比条件下),远超进口钢丝绳,建议自己做对比疲劳寿命测试,磷化涂层钢丝绳正在全面取代各类光面钢丝绳,也可替代先镀后拔薄锌层镀锌钢丝绳使用(可通过盐雾试验检验耐蚀能力),使用寿命更长,单位使用成本更低,质量稳定性可靠性更佳,按照现在钢丝绳市场的大致价格,锰系磷化涂层钢丝绳的价格大约是光面钢丝绳的1.4-1.6倍,而使用寿命延长幅度远高于价格的增长幅度,所以,磷化涂层钢丝绳日均使用费用仅为光面钢丝绳的40-55%,使用成本更低,性价比更高。
2.镀锌钢丝绳,包括热镀锌和电镀锌两种,一般热镀锌锌层厚,电镀锌锌层薄
3.不锈钢丝绳,以304或316不锈钢为主,防腐蚀效果非常优秀但是价格昂贵
4.涂塑钢丝绳,碳素钢丝绳基础上,外层涂覆聚乙烯、聚丙烯或尼龙
5.光面钢丝绳,使用寿命短,市场需求剧减,将被磷化涂层钢丝绳全面淘汰。
6.海洋工程系泊用钢丝绳
7.缆索钢丝绳
大气环境中使用的起重机械,优选锰系磷化涂层钢丝绳,重腐蚀环境优选热镀锌—磷化双涂层钢丝绳,海水中优先海工钢丝绳。采购时请注意,在购货发票必须注明钢丝绳名称,如磷化涂层钢丝绳或316不锈钢丝绳,防范不法企业侵害自身合法权益,另外,专利产品一般在钢丝绳外包装上有专利号喷涂标注,质保书应有主要技术指标,如磷化膜种类和膜重(磷化膜膜重大小、耐磨性、耐蚀性等对钢丝绳使用寿命有重要影响),仅供参考。
