• intros：{"brand_intro":"东华链条集团成立于1991年，总部位于浙江杭州，是中国最大的链条制造商，全球排名前五。创始人宣碧华以\"替代进口\"为使命，从农机链条起步，逐步攻克汽车、矿山等高强度领域。东华拥有国家级企业技术中心，其自主研发的\"强化喷丸\"工艺使链条疲劳寿命提升40%。公司品控严格遵循ISO/TS 16949体系，产品出口至欧美日等50多个国家，是卡特彼勒、三一重工的长期供应商。在中国市场，东华以\"高性价比的工业级品质\"著称，被誉为\"国产链条之光\"。","product_intro":"24A-1是东华针对矿山、建材行业推出的重载提升链，定位中高端工业市场。核心卖点：链板采用40Cr合金钢经调质处理，硬度达HRC 38-42；销轴经碳氮共渗，表面硬度HRC 58以上，耐磨性比普通链条高2倍。适用于斗式提升机、刮板输送机等重粉尘、高冲击场景。相比进口品牌，东华24A-1价格低40%，但抗拉强度（128kN）接近椿本同级产品；相比小厂链条，其链板孔位精度高，安装时无需扩孔，节省人工成本。","key_specs":{"材质":"40Cr合金钢链板+20CrMnMo销轴","节距":"38.1mm，适配24A链轮","抗拉强度":"128kN，满足矿用MT/T 465标准","硬度":"链板HRC 38-42，销轴HRC 58-62","表面处理":"发黑+防锈油，盐雾试验≥72小时"}}
