• intros：{"brand_intro":"东方雨虹（股票代码002271）成立于1995年，总部北京，是中国防水行业市值最高的上市公司，被誉为'防水茅'。创始人李卫国毕业于湖南大学，以'为人类为社会创造持久安全的环境'为使命。公司拥有亚洲最大的防水材料生产基地，止水带产品线覆盖橡胶、PVC、金属等多种材质。雨虹品控以'零容忍'著称，每批次产品留样十年追溯。2023年营收超300亿元，品牌价值连续多年行业第一。","product_intro":"雨虹YH-PVC系列塑料止水带采用聚氯乙烯（PVC）为基材，添加增塑剂和稳定剂，具有优良的柔韧性和低温弯折性（-20℃不脆裂）。核心卖点是'轻便易施工'——重量仅为橡胶止水带的1/3，且可热风焊接成任意形状。适用于中小型水池、渠道、挡土墙等低水压场景。相比橡胶止水带，PVC材质耐微生物侵蚀能力更强，且价格低廉。竞品对比中，雨虹PVC止水带的拉伸强度（≥18MPa）优于多数同类产品。","key_specs":{"材料":"聚氯乙烯（PVC）","拉伸强度":"≥18MPa","低温弯折性":"-20℃无裂纹","加热损失率":"≤3%（80℃×168h）","规格":"280mm宽×6mm厚","适用场景":"低水压、非变形缝"}}
