Description

一种新型复合保温管
技术领域:
本实用新型涉及一种新型结构的管道,准确地说是一种新型复合保温管,属于供热输送管道技术领域。
背景技术:
在现有的供热输送管道中,通常采用石棉、麻布、海绵泡沫作为保温材料,缠绕在金属管道表面,达到保温目的,采用上述结构,没有密封保护层,由于其保温材料有的吸水性强,有的耐腐蚀性差,降低了保温效果,影响了供热输送管道质量。
发明内容:
本实用新型公开一种新型复合保温管,目的旨在克服现有供热输送管道吸水性强、耐腐蚀性差的问题。
本实用新型的技术解决方案如下:在钢质的管道本体表面复合有一层球硅和聚氨酯泡沫混合的保温层,保温层的外侧为防腐密封保护层。
所述的球硅为原煤中氧化硅经高温陪烧成的一种颗粒结晶,表面为球型,中空壁薄,热传导和热对流系数低,可有效阻挡热辐射,耐800~1200℃高温保温层的厚度为4~8cm,密封保护层的厚度为0.3~1.0cm。
本实用新型的积极效果在于:管道表面复合有球硅和聚氨酯泡沫保温层,导热系数低,热损失小,抗压强度高,不吸水,耐高温,树脂密封保护层具有密封耐腐蚀防渗漏的特点,防止水分浸渗,提高了管道供热质量。
附图说明:
1~管道本体、2~保温层、3~密封保护层、4~球硅。
具体实施方式:
参照图1,由聚氨酯构成的保温层2中均匀分布有球硅4,厚度为8cm,并复合在钢质的管道本体1的表面,保温层2的外层为密封保护层3,采用TO树脂或聚乙烯材料,构成新型复合保温管。
