【product name】：室内膨胀型钢结构防火涂料

【English name】：Indoor expansion steel structure fireproof coating

1. The surface of the component is first subjected to rust removal, dust removal, and cleaning, and then coated with anti rust and anti-corrosion paint as the base coat;

2. After the anti-corrosion coating dries, apply the fireproof coating;

3. Based on the on-site construction situation, the first layer of roughening is carried out with a ratio of powder: adhesive=100:20. The mixture (powder, adhesive, water with 

moderate consistency) is mixed evenly with a building mortar mixer, and then roughened with a construction thickness of about 2-7mm;

4. After the coating to be roughened is dried (at room temperature for about 8 hours), the second coating can be applied. The reference ingredient ratio is powder: water=1:1. 

Mix the mixture evenly, and then spray or apply with a building plastering knife. The construction thickness is about 5-30mm;

5. The third construction procedure is the same as above, until the thickness required by the design is reached;

6. During winter construction, it is advisable to add an appropriate amount of antifreeze to prevent the surface of the fireproof coating from freezing (construction is not recommended 

when the surface temperature of the component is below 5 ℃);

7. In a hot, dry, and windy climate, pay attention to watering and shading maintenance to avoid affecting the quality (construction is not recommended if the surface temperature of 

the component is above 45 ℃ and the wind force is greater than level 4);

8. If the coating thickness exceeds 20mm, it is recommended to stick nails and hang nets.

matters needing attention:

1. This product cannot be mixed with other coatings or paints.

2. Unused paint during construction must be sealed and stored; Once the powder is opened, it should be used immediately to avoid moisture and clumping, and cannot be used.

3. The paint should be stored in an environment of 5-30 ℃, and freezing, anti moisture, and direct sunlight are strictly prohibited.

4. Do not mix too many ingredients at a time, mix as much as you need;

5. Coatings that have been left for too long and have begun to harden should not be reused.

Packaging and Storage:

1. The product is packaged in a woven bag with a 25kg inner lining film (or coating);

2. The product can be stored for 6 months under ventilated, dry, and shaded conditions;

3. During transportation, the product should be protected from rain, exposure to sunlight, and freezing, and comply with the relevant regulations of the transportation department.

1、构件表面先进行除锈、除尘、去污，底涂涂装防锈防腐涂料；

2、待防腐涂料干燥后，进行防火涂料的涂装施工；

3、以现场施工情况，第一遍拉毛，配料的比例为粉料:胶料=100:20，将混合物（粉、胶、水适度稠度混合）用建筑灰浆搅拌机搅拌均匀，之后拉毛施工，施工厚度约为2~7mm;

4、待拉毛施工的涂层干燥后（常温条件约8h）再进行第二遍涂层的施工，参考配料比例为粉料:水=1:1，将混合料搅拌均匀，之后喷涂施工或建筑抹灰刀涂抹施工，施工厚度约为5-30mm；

5、第三遍施工程序同上，直至达到设计要求的厚度；

6、冬季施工时，加入适量防冻剂，以达到防火涂料表面不上冻为宜（构件表面温度低于5 ℃不建议施工）；

7、炎热干燥大风气候，注意洒水遮荫养护，以免影响质量（构件表面温度高于45 ℃风力大于4级不建议施工）；

8、涂层厚度超过20mm，建议粘钉挂网。

注意事项：

1、本产品不能同其它涂料、油漆相混。

2、施工时未用完的涂料，须密封保存；粉料一经开启，立即使用，以免受潮结块则不能使用。

3、涂料应在5-30 ℃的环境下保存，严禁冻结，反潮，严禁暴晒。    

4、每次配料不宜过多，用多少配多少；

5、放置时间过长且开始硬化的涂料不宜再用。

包装及储运：

1、产品采用25kg内衬薄膜（或涂膜）的编织袋包装；

2、产品在通风、干燥、荫凉的条件下可储存6个月；

3、产品在运输时，防止雨淋、爆晒、冷冻，并遵守运输部门的相关规定。
