聚氨酯密封膏施工注意事项 
Polyurethane sealing paste construction precautions
1）适用期：双组分密封膏甲、乙组分混合后，混合料逐渐变稠，**过适用期就不能使用。
Applicable period: After the two-component sealing paste is mixed, the mixture is gradually thickened and cannot be used beyond the applicable period.
使用时的环境温度对密封膏的固化起相当大的作用，气温越高适用期越短，气温过低时固化速度变慢，施工温度以5℃～35℃为宜。 
The ambient temperature during use plays a considerable role in the curing of the sealing paste. The higher the temperature, the shorter the application period is. When the temperature is too low, the curing speed is slow, and the construction temperature is preferably 5℃to 35℃.
2）使用时，密封材料的宽深比例要适当。
When used, the aspect ratio of the sealing material should be appropriate. 
3）密封膏贮存时要避免阳光直射，宜放在阴凉干燥处，远离火源；特别要注意包装桶密封完好，有效期一年。
When storing the sealing paste, avoid direct sunlight. It should be placed in a cool and dry place, away from the fire source; pay special attention to the sealed barrel, which is valid for one year.
