  1、玻璃鱗片防腐材料可以說是煙囪防腐施工中常用的材料了,耐溫耐酸,硬度高,但附著力差,簡略成片墜落,泡沫玻璃磚和玻璃鱗片是比較多見的。
  2、其次是耐酸膠泥防腐,其耐溫性及耐酸性能好,有一定的附著力,運用壽命長。但防水防潮性差,簡略吸收煙氣中的水分粉化墜落,極簡略發作裂紋。
  3、玻璃鋼防腐:玻璃鋼系列的煙囪防腐材料因為其內表光滑,不簡略發作積垢,耐熱、耐磨、耐酸。但是彈性模量低,不耐老化,長期耐溫性欠好。不銹鋼防腐材料耐酸耐堿、耐高溫,外表光滑、阻力小、抗沖擊,但焊縫簡略遭到腐蝕,不簡略成型,造價也高。
  4、莫來石防腐在煙囪防腐施工中并不是多見的,它有著脹大均勻、熱震穩定性極好、荷重軟化點高、抗化學腐蝕好的特征,但是簡略發作裂紋,防腐防水性低,質量大,粘接難度也大,所以不被看好,運用的也少。公司網址:www.smartdu.com
