• intros：{"brand_intro":"卡勒克（Garlock）是美国EnPro工业集团旗下品牌，成立于1887年，拥有超过130年密封件制造历史。公司以发明螺旋缠绕垫片和KLOZURE油封闻名，是全球工业密封领域的\"百年老店\"。卡勒克在中国设有苏州工厂，品控遵循ASTM国际标准。其填料密封产品线以碳纤维、石墨、PTFE复合材料为核心，尤其擅长高温高压工况。创始人Thomas Garlock最初为蒸汽机车设计密封件，奠定了公司\"解决极端工况泄漏\"的技术基因。","product_intro":"3000系列碳纤维编织填料密封，采用高强度碳纤维丝编织，浸渍PTFE和特种润滑剂。定位中高端工业阀门与泵类密封，特别适用于高温热水、蒸汽、导热油及弱酸碱介质。核心卖点是\"高导热+低磨损\"：碳纤维导热系数是普通PTFE的10倍，能快速将摩擦热带走，防止轴面过热。相比传统石墨填料，其抗挤出性更好，不易产生颗粒污染。在造纸、电力、石化行业有广泛应用。与戈尔ePTFE相比，价格更低，但耐腐蚀性稍弱。","key_specs":{"材料":"碳纤维 + PTFE浸渍","耐温范围":"-100°C ~ +450°C（蒸汽中可达+650°C）","耐压范围":"最高25 MPa（静态）","适用介质":"热水、蒸汽、导热油、弱酸弱碱","导热系数":"0.8 W/(m·K)","编织方式":"方形编织，四角密实"}}
