FG深冷粘結劑

DZGR-FZ-100
FG Deep-Cold Bonding Agent
FG深冷粘結劑

FG是一種石油瀝青為基料,加入有機深劑及高分子樹脂等材料和有機增塑劑原料加溫反應而成。具有粘結力強、抗凍性好、能在深冷部位對泡沫玻璃和非深冷層聚氨酯等材料粘結成型。有較好手柔韌性和低溫粘結力。所以,在石油、化工、設備管道等隔熱保冷部位-196℃~+60℃以內有較好的粘結力。是保冷、隔熱的專用粘結劑。

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、使用時先將粘接劑加熱180℃~200℃溶化。
  • 用刮刀、棕刷或自制把等工具,將溶化的粘結劑抹在泡沫玻璃或聚氨酯粘合面上趁熱粘合壓緊,待稍冷固定后刮去多余粘結劑,粘結劑涂薄均勻,粘合縫無空隙。
  • 粘結劑隨用隨熔,不易長時間加溫或溫度過高,一般可用煙色來判斷,青-白-黃,黃已近火點,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.
