合兴钢结构浅谈钢结构厂房保温降温

发布时间:2015-9-8 9:30:34 浏览次数:641




    钢结构厂房保温能隔绝大部分的太阳光辐射和传导热量,减少室内形成温室效应。从而极大的降低厂房的温度,改善钢结构厂房的环境。现在常用的方法有以下两种选择:


给钢结构厂房屋面加盖保温棉,一般屋面上使用的保温棉是玻璃棉,常用厚度为50mm,75mm,100mm,密度为10kg/m

安装好一般可以使室内温度降低5-8℃,施工过程较复杂,若为旧厂房做保温改造,需要拆除原有屋面,拉上钢丝网,在钢丝网上铺设玻璃棉,盖上原有屋面板,再做防水处理。

在屋面板上喷涂高效的隔热反射涂料。此种产品隔热保温性能极佳,可以在金属、混凝土、灰墙、木结构表面、石棉瓦、塑料、玻璃钢、橡胶等各种表面涂覆。涂层0.25mm厚,其效果相当于10cm-15cm玻璃棉的功效,它可以反射99.5%红外线,92.5%可见光,最高隔音效果达68%,平均隔音效果50%以上。防火A级,完全不燃。无毒安全,长效耐久,使用寿命15年以上(详细介绍可以参照工程材料档)。若用此法,施工方便,对原有屋面无损坏,而且能阻止屋面的老化。施工后和施工前的板材表面温差最大可达20℃,室内温差可达8-10℃,钢结构厂房能耗可锐减30-70%。




Steel structure factory building insulation can cut off most of the solar radiation and heat conduction, reduce indoor form the greenhouse effect. Thus greatly lower the temperature of the plant, improve the environment in the steel structure factory building. Now commonly used method has the following two options:

To the steel structure factory building roofing heat preservation cotton, is generally used on roofing heat preservation cotton wool, commonly used thickness of 50 mm, 75 mm, 100 mm, the density of 10 kg/m

Installed in general can lower the indoor temperature 5-8 ℃, construction process is complicated, if do insulation improvement for old factory building, need to dismantle the original roof, Shanghai silk screen, in the wire online laid glass wool, cover the original roof board, then do waterproof processing.

On the roof plate spraying and efficient heat reflective coating. This product is excellent insulating performance of insulation, can be in metal, concrete, kind, wood surface, asbestos tile, plastic, glass fiber reinforced plastic, rubber and coating on the surface. 0.25 mm thick coating, the effect is equivalent to 10 cm to 15 cm the effect of glass wool, it can reflect infrared, 99.5% 92.5% of visible light, sound insulation effect was 68%, and the highest average sound insulation effect of more than 50%. Fireproof grade A, don't burn completely. Non-toxic safety, long-term durability, service life is more than 15 years (details can be reference to engineering materials). If using this method, construction is convenient, the original roof no damage, and can prevent the roof of the aging. Before construction and after construction of the plate surface temperature of 20 ℃, largest indoor temperature can reach 8-10 ℃, the steel structure factory building energy consumption can be reduced to 30-70%.
