材料选择的关键考量因素
Key considerations for material selection
工况适配性
Adaptability to working conditions
高温环境优先选用石棉芯或耐高温合成纤维芯；重载场景推荐金属芯；需要频繁弯曲的场合则应选择天然纤维芯。
Priority should be given to using asbestos cores or high-temperature resistant synthetic fiber cores in high-temperature environments; Recommended metal core for heavy-duty scenarios; In situations where frequent bending is required, natural fiber cores should be chosen.
成本效益平衡
Cost benefit balance
黄麻芯成本 为金属芯的1/3，但使用寿命缩短40%；PP芯虽初期投入较高，但维护成本可降低60%。
The cost of jute core is one-third of that of metal core, but its service life is shortened by 40%; Although the initial investment in PP core is relatively high, maintenance costs can be reduced by 60%.
环保与安全
Environmental Protection and Safety
石棉芯需严格管控粉尘排放；合成纤维芯需通过RoHS认证，确保无有害物质析出。
Asbestos cores require strict control over dust emissions; Synthetic fiber cores must pass RoHS certification to ensure no harmful substances are released.
