    通风管道为什么要进行防腐保温?
    来源:www.w-j-e.com 2019-03-07 13:17:34
    大家都知道░,山东通风管道具有送新风和排气的作用░,将有害气体排出室外░,把室外新鲜空气送至室内。在我们使用安装时还需要做好防腐保温░,那么为什么要进行防腐保温操作呢?接下来跟随小编一起来了解一下。
    As we all know, Shandong ventilation pipeline has the function of supplying fresh air and exhausting gas. It can discharge harmful gas outdoors and send fresh air outdoors to indoors. When we use and install, we also need to do a good job of anti-corrosion and heat preservation, so why should we carry out anti-corrosion and heat preservation operation? Next, follow Xiaobian to understand.
    一般情况下使用镀锌铁管░,有腐蚀性及特别潮湿的场所使用不锈钢管。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。对输送高温•●、高湿气体的风道内壁宜喷刷磷化底漆或其他耐蚀涂料。在风道输送高温气体或低温空气时░,风道外壁应做保温(保冷)处理。
    Generally, galvanized iron pipes are used, and stainless steel pipes are used in corrosive and especially humid places. When the ambient air humidity is relatively high, the outer wall of the duct needs to be treated with anti-corrosion and anti-rust. Phosphating primer or other anti-corrosion paint should be sprayed on the inner wall of the air duct conveying high temperature and humidity gas. When conveying high temperature gas or low temperature air in the duct, the outer wall of the duct should be treated with heat preservation (cold preservation).

    另外░,输送高温气体风管的保温目的░,一是防止山东通风管道内空气的热损失(出现在冬季集中空调系统);二是防止在输送废热蒸汽或高温气体时阻止热量散发到房间内而使室温升高░,并且还防止人接触风道而被烫伤。而在夏季往往因输送气体的温度低于周围环境的空气露点温度时░,管道外壁会产生结露现象。这对集中空调系统的风道会加大冷量损失░,同时凝结水滴会污染吊顶和墙地面░,因此也应该进行保冷隔热处理。

    In addition, the purpose of heat preservation of air duct conveying high temperature gas is to prevent the heat loss of air in Shandong ventilation duct (occurring in winter central air conditioning system); to prevent the heat from radiating into the room while conveying waste heat steam or high temperature gas, and to prevent people from contacting the air duct and being scalded. In summer, when the temperature of conveying gas is lower than the dew point temperature of surrounding air, condensation will occur on the outer wall of the pipeline. This will increase the loss of cooling capacity in the air duct of central air conditioning system, and condensate droplets will pollute the ceiling and wall surface, so it should also be cold insulation and heat treatment.
    上述就是为山东通风管道做防腐保温处理的原因░,只有进行防腐保温░,才能在之后的使用过程中减少腐蚀的现象发生░,因此我们要注意以上小编提到的这些方面░,保证在后续的使用中发挥更好的效果。
    The above is the reason for Shandong ventilation pipeline to do anti-corrosion and heat preservation treatment. Only by carrying out anti-corrosion and heat preservation, can the corrosion phenomenon be reduced in the later use process. Therefore, we should pay attention to these aspects mentioned in the above sub-section to ensure better effect in the subsequent use.
