FG深冷粘结剂

DZGR-FZ-100
FG Deep-Cold Bonding Agent
FG深冷粘结剂

FG是一种石油沥青为基料,加入有机深剂及高分子树脂等材料和有机增塑剂原料加温反应而成。具有粘结力强、抗冻性好、能在深冷部位对泡沫玻璃和非深冷层聚氨酯等材料粘结成型。有较好手柔韧性和低温粘结力。所以,在石油、化工、设备管道等隔热保冷部位-196℃~+60℃以内有较好的粘结力。是保冷、隔热的专用粘结剂。

FG is obtaired by using petroleum pitch as the base mixed with organic advent and macrom clecular resin, organic plasticizer before heated for reaction. It is ireatured in high bonding, good winter resistance and can bond materials such as foamed glass at the deep freeze locations and polyurethane at non-deep freeze layers, with excellent flexibility and adhesive force at low temperature. As a result, it shows good adhesive force at insulating locations of petroleum, chemical industry and equipment pipelines within arange of 196℃~+60℃. It is a special-purpose bonding agent to be used at insuating applications.

使用方法Usage

  • 1、使用时先将粘接剂加热180℃~200℃溶化。
  • 用刮刀、棕刷或自制把等工具,将溶化的粘结剂抹在泡沫玻璃或聚氨酯粘合面上趁热粘合压紧,待稍冷固定后刮去多余粘结剂,粘结剂涂薄均匀,粘合缝无空隙。
  • 粘结剂随用随熔,不易长时间加温或温度过高,一般可用烟色来判断,青-白-黄,黄已近火点,要加注意。
  • When using it, first heat the bonding agent under 180℃~200℃ to melt it .
  • Use scrappers or lorushes or lself-made tools apply the melted bonding agent on the foam glass or polyurethane bonding face and press light when it is hot. When it cures, scrape the redundant bonding agent. The bonding agent shall be homogenously applied and no clearance shall exist.
  • The bonding agent melted melted shall be used up immed ately. It is not suggested to heat it for a long time or under too high atemperature. usually, you can judge it through the color, which turns from green to white and then to yellow. When it becomes yellow, it has approached flash point and special care shall be taken.
