    核心优势


    1. 优异的耐高温性能

    普通型使用温度可达1000℃,高铝型/含锆型可达1260-1430℃

    高温下保持结构稳定,线收缩率低(1000℃保温24小时≤4.0%)


    2. A级不燃防火

    燃烧性能达到A(A1)级,遇火不燃烧、不释放有毒烟雾

    符合电力、石化、建筑等领域的严苛消防规范


    3. 极低导热系数

    导热系数低至**0.034 W/(m·K)**(常温)

    500℃平均温度下≤0.182 W/(m·K)

    大量静止空气被封闭于纤维孔隙中,隔热效果突出


    4. 优异的热稳定性与抗热震性

    可承受剧烈的温度波动而不开裂、不剥落

    特别适用于间歇式窑炉、频繁启停的热工设备


    5. 良好的机械性能

    纤维柔韧富有弹性,抗拉强度高(针刺毯≥10-35kPa)

    可缓冲设备振动,避免硬质材料碎裂脱落


    6. 化学稳定性强

    除氢氟酸、强碱外,耐多数腐蚀性介质

    用于覆盖奥氏体不锈钢时,浸出液离子含量可控(特制低腐蚀型)


    7. 施工便捷

    轻质柔软,可任意裁剪,贴合弯头、阀门等异形部位

    产品形态丰富,可定制异形件满足特殊需求

常见问题

建筑保温材料主要有哪些类型?各有什么优缺点?


无机保温材料(如岩棉、玻璃棉、泡沫玻璃):
优点:防火性能好(A级不燃)、透气性佳、稳定性高。
缺点:导热系数略高于有机材料、吸水率较高、施工易产生纤维粉尘。
有机保温材料(如EPS聚苯板、XPS挤塑板、PU聚氨酯):
优点:导热系数低、保温效果好、质轻、施工便捷。
缺点:防火等级多为B级(需添加阻燃剂)、高温易变形、耐久性稍差。
复合保温材料(如保温一体板、真空绝热板):
优点:综合性能优、施工效率高、部分可达A级防火。
缺点:成本较高、对基层平整度要求严格。

如何选择适合项目的保温材料?


需综合以下因素:
防火要求:高层建筑(>100m)需A级材料;低层可用B1级(难燃)。
气候条件:严寒地区优先选导热系数低的材料(如PU、XPS);潮湿环境需低吸水率(如XPS、泡沫玻璃)。
基层类型:混凝土墙面多用板材;复杂造型可选用喷涂聚氨酯或保温砂浆。
经济性:EPS成本最低;真空绝热板贵但薄。
政策法规:部分地区禁用B2级材料,需查询当地标准。
