排烟罩的防腐防锈
编辑:淄博金冠厨房设备有限公司   时间:2017-11-01

在夏天排烟罩往往因运送气体的温度低于周围环境的空气露点温度时,管道外壁会发生结露现象。这对会合空调系统的风道会加大冷量丢掉,一起凝集水滴会污染吊顶和墙地上,因此也应该进行保冷隔热处理。

In summer, when the temperature of the conveying gas is lower than the ambient dew point temperature, the outer wall of the pipe will be condensation. The air duct of the central air conditioning system will increase the loss of cooling capacity. At the same time, the condensation of water droplets will pollute the ceiling and the wall and ground. Therefore, it is also necessary to carry out cold insulation and heat insulation treatment.

当风道运送一般气体时,对黑钢板风道应进行除锈、刷防锈漆处理,对含尘气体可喷涂防磨损保护层,当周围环境空气湿度较大时,风道外壁需做防腐蚀、防锈处理。对运送高温、高湿气体的镀锌钢板风道内壁宜喷刷磷化底漆或其他耐蚀涂料。

When the air conveying gas, the black plate ducts shall be rust, antirust paint brush, the dust gas can be coated with anti abrasion protective layer, when the surrounding ambient air humidity, air duct wall to do anti-corrosion and anti rust treatment. For the transmission of high temperature, high humidity gas galvanized steel, the wall should be sprayed brush phosphating primer or other anti-corrosion coating.

排烟罩运送高温、高湿气体的镀锌钢板风道内壁宜喷刷磷化底漆或其他耐蚀涂料。在风道运送高温气体或低温空气时,风道外壁应做保温(保冷)处理。

For the transmission of high temperature, high humidity gas galvanized steel, the wall should be sprayed brush phosphating primer or other anti-corrosion coating. When conveying high temperature air or low temperature air in the air duct, the outer wall of the air duct shall be insulated (cold preserved).
