白色阻燃玛蹄脂

DZGR-FZ-50
White Flame Retardant Mastic
白色阻燃玛蹄脂

白色玛蹄脂是以改笥环氧为基料,加入适量的阻燃剂、增塑剂和填料精制而成。产品呈灰白色,毒性低、吸水率小、不透气、密封性好,常温下可以施工,干燥后具有阻燃性。它是低温保冷工程 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

  • 首先应清除泡沫玻璃、聚氨酯泡沫塑料保冷层外表的油污及灰尘,高低不平的地方用腻子补平。
  • 在清理干净的泡沫玻璃、聚氨酯泡沫塑料外表粉刷1~1.5mm厚的白色玛蹄脂作底层。
  • 待底卖劲玛蹄脂稍干时外缠一层粗格玻璃布或塑料窗纱。
  • 在粗格玻璃布或塑料窗纱再抹2~2.5mm厚的白色玛蹄脂,能接触后用手醮脂能后用手水抹光。
  • First you should clean the oily stains and dust?on the surface of insulating layers of foam glass and polyurethane foam plastic. Use a putty to mend the uneven places.
  • On the clean surface of foam glass or polyurethane foam plastic, apply white mastic 1 to 1.5mm thick as the base.
  • After this layer of mastic is a little dry, put alayer of rough glass or plastic window gauze.
  • After another layer of white mastic 2 to 2.5mm thick on the rough glass fabric or plastic window gauze. After it dries and allows handtoch, smoothen it with hand and soap water.
