YFYJ型有机防火堵料 Type YFYJ organic fireproof plugging material
　YFYJ型有机防火堵料是一种以有机材料为主要成分的固状柔性防火材料，适用于电缆及管道等贯穿孔洞、缝隙的封堵。特别适用于成束电缆或密集区域的阻火封堵。该产品具有耐火时间长，发烟量低，耐油，耐腐蚀等特性，并具有良好的可塑性。施工方便，更换，增减电缆容易。在封堵较大孔洞时，一般与其他封堵材料组合使用。
Type YFYJorganic fireproof plugging material is a kind of solid flexible fireproof material whose main component are organic materials.lt is applicab-le for plugging breakdown holes or gaps on cables or pipes,especially be used in the fire isolation of the places where serried cables exists lt has the characteristics such as long fire endurance,less smoke oil resistance,corro-sion resistance and good plasticity eaat for construction replacement and adding or subtracting cables.Generally it is used together with other plugging materials when it is uesd to plug large holes.
施工方法 Construction
○先将需实施阻火封堵部位的污物清理干净，适当整理电缆，清除表面油污、灰尘等杂物。
○根据需封堵的孔洞大小，确定其用量，将该堵料揉和后用合适工具均匀密实地铺（嵌）于需封堵的孔洞中，做到表面平整、整齐、不留任何间隙。
○如气温偏低，堵料较硬，不便施工时，可将其置于温热水中（50～80℃）间接加热，待柔软后再进行施工，严禁用明火直接加热
○封堵较大的孔洞时，建议与PFB型防火包或WFD型无机防火堵料配合使用更佳。
○First,clean the places where need fire-retardant mend neaten the cables,clean out the smear and dust etc,On the su rface.
○Determine the quantity according to the sizes of hole needing mend Knead the mend materials and then put them in the hole uniformly and densely with suitable tools Requi rements:the surface should be smooth and neat and remains no gaps.
○lf lower atmosphere temperature and hard mend material which are not convenient forconstruction you can put the material lnto the warm water(50 to 80℃) and intenerate it but pay attention to not heat the material with fire directly.
○When mending relatively large holes you are suggested to use it together with PFB fire safety package and WFD
