施工要求:
1.表面处理：
(1)施工前，钢结构表面的锈迹锈斑应彻底除掉。因为它影响涂层的粘结■力。表面的防锈处理按《钢结构工程施工与验收规范》标准。除锈之后须进行防锈处理，需要涂70-1带锈底漆，因为防腐涂料为︻水乳型涂料，
直接涂刷钢材基面生锈。
2.施工前的准备：

(1)出厂时已经配〇制好的涂料，不论是面层或底层涂料，都应搅拌均匀才能使用。施工现场一般用便携式的电动搅拌器搅▂拌涂料。调配和搅拌好的涂料应当稠度适宜，喷涂时不发生流淌和下坠现象为宜。

过稠可用自来水稀▲释。

(2)对不需喷涂的设备、管道、墙面和门窗，要遮蔽保护，否则喷上该涂料难以清洗◥干净。

3.施工环境：

钢结构防火涂料施工的气候条件:在施工过程中和施工之后，涂层干燥固化之前，环境温度宜在5~50°C，相对湿度不大于90%，空气应流通，若在温度过低或温度太高或风速在5m/s (四级)以上或钢结构构件表面有结露时，都不利于防火涂料喷涂施工。

4.施工方法：

(1)该∮防火涂料的施工，由于底层涂料- -般较粗糙,宜采用重力式施工要求(或斗式)喷枪， 配自动调压0.6-0.9m2/mm的空气压缩机，哧◢嘴直径中4-6mm,空气压力0.4-0.6Mpa。

局部修补私小面积施工，面层装饰╳涂料，可用刷涂、喷涂或滚涂，用其中一-种或多种方法方便地施工。用于喷底层涂料的喷枪嘴可调直径1-3mm时，也可用于喷面层涂料。如人工涂♂刷，涂刷道数相应增加。

(2)喷涂时每遍厚度不超过0.5mm,晴朗天∏气情况下，每间隔8小时喷涂一次。喷涂后一道涂料时，必须在前-道干燥后，再喷涂后一道。人工涂刷每道厚度较薄↘，按照厚度，测算道数。
(3)根据被涂钢结构的耐火时间要求确定相应的涂层厚度，每平方米每喷1mm厚的涂层理论耗用湿涂料1-1.5kg。
5.使用量：
2mm厚涂层，理论耗量2kg/m2防火级别1小时，涂刷6-8道; 5mm厚涂层，理论耗量4.8kg/m2,防火级别2小时，涂刷10道以上。

运输与贮存:本涂料属水△性涂料，不燃不爆无←毒害，可用汽车、飞机、火车和轮船等交通工具按非危险品运输，在5-50°C阴凉、干燥、通风的环境中，贮存有↑效期12个月。

7.0 thin section steel structure expansion fire retardant coating
The fireproof coating 7.0 is used in gymnasium, exhibition hall, power plant, station waiting room and bare load-bearing steel structure of industrial factory building, which plays the role of fire protection and decoration.
3.68MB)-Mini View King-26 / 27 132 per cent
Fire prevention foundation: ductile elastic Ke 7.0 coating sprayed on the surface of steel structure, usually plays a decorative role, if in the event of fire can expand and thicken carbonization, form a spongy carbon layer that is not easy to burn, so as to improve the fire resistance limit of steel structure to more than 1.5 hours, win fire fighting time, and effectively protect steel structure buildings from fire.
Performance characteristics:
1. The coating is thin and can be used as a smooth or sticky decorative coating of all colors. two。 This product does not contain organic solvents, non-toxic to the human body.
3. The construction is convenient.
4. High strength: when applied, there is no need to reinforce barbed wire with fire protection coating. 5. It is firmly bonded to steel and will not be shot down by a blunt force.
6. The main technical data for testing physical and chemical mechanical properties according to the testing methods prescribed by the State for Fire retardant Coatings for Steel structures are as follows:

Construction requirements:
1. Surface treatment:
The main results are as follows: (1) before construction, the rust spot on the surface of steel structure should be completely removed. Because it affects the adhesion of the coating. The antirust treatment of the surface is in accordance with the Standard of "Code for Construction and acceptance of Steel structure Engineering". Rust prevention must be carried out after rust removal, and 70-1 rust primer should be applied because the anticorrosive coating is water emulsion coating.
Rust the base surface of the steel directly.
two。 Preparation before construction:
The main results are as follows: (1) the paint that has been prepared when it leaves the factory, whether it is the surface layer or the bottom coating, should be stirred evenly before it can be used. Portable electric agitator is usually used in the construction site to stir the coating. The coating with good mixing and mixing should be thicker, and it is appropriate not to flow and fall when spraying. Excessive thickening can be diluted with tap water.
(2) for equipment, pipes, walls and doors and windows that do not need to be sprayed, it is difficult to clean up if the coating is sprayed.
3. Construction environment:
The climatic conditions of steel structure fire prevention coating construction: during and after construction, the ambient temperature should be 5 ~ 50 °C, the relative humidity should not be more than 90%, and the air should flow. If the temperature is too low or the temperature is too high or the wind speed is above 5m/s (grade 4) or the surface of steel structure members are exposed, it is not conducive to the construction of fire prevention coating spraying.
4. Construction methods:
The main results are as follows: (1) because of the rough bottom coating, gravity should be adopted in the construction of the fire retardant coating.
Construction requirements (or bucket type) spray gun, equipped with automatic pressure regulation 0.6-
0.9m2/mm air compressor, 4-6 mm in diameter, air pressure 0.4-0.6Mpa. Local repair private area construction, surface decoration coating, can be brushed, sprayed or rolled coating, with one or more of the methods to facilitate the construction. The nozzle can adjust the diameter of 1-1-1-1-1-1-1-1-1-1-1 for spray coating.
3mm can also be used in spray coating. If the manual brush, the number of brush channels increases accordingly.
(2) when spraying, the thickness shall not exceed 0.5mm, and in sunny weather, spraying shall be done at intervals of 8 hours. When spraying a coating, it must be dried before and after spraying. Manual brush each thickness is thin, according to the thickness, calculate the number of channels.
(3) according to the fire resistance time requirements of the coated steel structure, the corresponding coating thickness is determined, and the wet coating 1-1.5kg is used for each square meter of 1mm thickness.
5. Usage:
2mm thick coating, theoretical consumption 2kg/m2 fire protection grade 1 hour, brush 6-8 channels, 5mm thick coating, theoretical consumption 4.8 kg ≤ m2, fire protection level 2 hours, brush more than 10 channels.
Transportation and storage: this coating is waterborne coating, non-flammable, non-explosive and non-toxic, can be used for vehicles, aircraft, trains and ships and other means of transportation according to non-dangerous goods, in 5-50 °C cool, dry, ventilated environment, the storage period of 12 months.
