Description

一种地暖管道的清洗方法 技术领域
本发明涉及管道的清洗技术领域，特别涉及一种地暖管道的清洗方法。
背景技术
地热管道在使用一段后，管道内壁会有大量粘泥、细菌及水垢的产生，附着在管道内壁，形成管道堵塞，导致水流循环不畅、散热不够，严重影响供暖温度及效果。有资料表明地暖在使用一年后，地暖管的内壁每增加1mm的污垢，就会导致供热室内温度下降6℃。这不仅影响了地暖的正常使用，而且也造成了能源的浪费。如长时间得不到有效的清洁处理，会使地热采暖系统出现故障，造成管内栓塞无法使用，甚至造成破坏地面，拆除或更换地热管路系统，给地暖用户造成财产损失与生活不便。故，会选择清洗剂对管道进行定期清理，但目前的管道清洗方法具有清洗效果不理想、对管道的腐蚀厉害、清洗不干净、浪费水资源等缺点。
为了克服上述缺点，本发明人积极创新，以期创设出一种清洁效果好的地暖管道的清洗方法。
