发布时间:2015-8-27 11:08:33 浏览次数:957

1.施工温度:施工期间,以及施工后24之内,施工周围环境及钢构件温度均应保持在5℃以上为宜。若不能满足此温度条件时,应另采取其它特殊措施,防止涂层受冻。当风速大于5m/s,或雨天和构件表面有结露时,不宜作业。


2.防火涂料在运输存放过程中要防雨防潮。


3.不需喷涂抹涂的部位,要在喷涂前盖住,一旦造成污染,应马上清洗干净。

4.若涂料在使用中若变稠时(不属时间过长硬化)可再加入少量水搅匀后再用。


5.施工时若有上、下立体交叉作业,应注意安全。特别是在脚手架上的操作人员要加倍小心,操作人员必须戴好防护用具,系好安全带后方可操作。


6.涂料喷涂后,宜用塑料布或其它物品遮挡,以免强风直吹和暴晒,造成涂层开裂。

7.喷涂工具停止使用后,应马上清洗干净,以备再用。

8.防火涂料当出现固化、结块时不得使用。刚施工完的涂层应防止雨水冲淋。

9.防火涂料初期强度较低,容易碰坏。因此,喷涂应在相关钢结构施工完后再进行,防止强烈震动和碰撞。





Temperature: 1. The construction during the period of construction, as well as within 24 construction, the construction of the surrounding environment and the temperature of steel members shall stay above 5 ℃ advisable. If can't meet the temperature condition, the other take special measures to prevent coating seas. When the wind speed is more than 5 m/s, or rain and component surface condensation, unfavorable assignment.

2. In the process of transportation for fire retardant coating to rain moistureproof.

3. No need to spray coating parts, daub to cover before spraying, once cause pollution, should be cleaned immediately.

4. If the coating is in use when thickening (not too much time in hardening) to add a little water stir well before use.

5. If there are upper and lower grade separation during the construction of operation, should pay attention to safety. Especially on the scaffolding operation personnel to be doubly careful, operators must wear protective gear, fasten your seat belt rear can operate.

6. After coating, appropriate cover with plastic cloth or other items, in order to avoid strong winds blowing straight and exposure, causing cracking.

7. After spraying tool to stop the use, should be cleaned immediately, for reuse.

8. When there is a fire retardant coating solidifying, agglomerate shall not be used. Just finished the construction of the coating should prevent rain shower.

9. The early strength is low, fire retardant coating easily damaged. Therefore, spraying shall be carried out after finish related to steel structure construction, prevent the strong vibration and impact.
