• intros：{"brand_intro":"同Heraeus Kulzer品牌，Technovit 7100是其经典热固化系列，专为高精度金相分析及硬组织切片设计。品牌延续德国精密制造传统，采用高纯度甲基丙烯酸酯单体，确保批次间一致性。其技术优势在于可调节的硬度范围（通过改变固化温度），适配从软塑料到硬陶瓷的多种材料。品控体系包含72小时老化测试，确保长期储存稳定性。","product_intro":"Technovit 7100 是一款热固化甲基丙烯酸酯树脂，定位中高端金相实验室。核心卖点是其优异的渗透性和低粘度（<50 mPa·s），可深入多孔材料（如陶瓷、烧结金属）内部实现全包裹。与Technovit 4000相比，固化时间较长（60-90分钟/60℃），但硬度更高（邵氏D 90+），适合需要高支撑力的硬质样本。适用场景包括地质岩相分析、复合材料界面观察及失效分析。","key_specs":{"固化方式":"热固化（50-70℃烘箱）","粘度":"45 mPa·s（25℃）","硬度":"邵氏D 90-95","收缩率":"1.5-2%（线性）","包装规格":"1kg/套（含固化剂）","适用材料":"金属、陶瓷、矿物、硬质塑料"}}
