白色阻燃瑪蹄脂

DZGR-FZ-50
White Flame Retardant Mastic
白色阻燃瑪蹄脂

白色瑪蹄脂是以改笥環氧為基料,加入適量的阻燃劑、增塑劑和填料精制而成。產品呈灰白色,毒性低、吸水率小、不透氣、密封性好,常溫下可以施工,干燥后具有阻燃性。它是低溫保冷工程 抹在保冷材料外面防水、防潮的理想密封材料。

White mastic is obtained by using modified epoxy polyethylene as the base mixed with an appropriate amount of fire retarding agent and plasticizer and fillers. The product is grayish white with low toxicity, low moisture absorption, air-tightness and good sealing performance. It can be installed under normal temperature and has fire-retarding nature after drieded. Therefore, it is an ideal waterprof and moisture preverting sealing material that can be applied on the insulating materials at low-temperature refrigerating engineering.

使用方法Usage

  • 首先應清除泡沫玻璃、聚氨酯泡沫塑料保冷層外表的油污及灰塵,高低不平的地方用膩子補平。
  • 在清理干凈的泡沫玻璃、聚氨酯泡沫塑料外表粉刷1~1.5mm厚的白色瑪蹄脂作底層。
  • 待底賣勁瑪蹄脂稍干時外纏一層粗格玻璃布或塑料窗紗。
