外墻巖棉板的熱工原理，迅速侵占外墻保溫材料商場--巖棉復合板、彩鋼復合板，這是很多企業在對廠房實行改建時間，挑選多的外墻保溫材料。在我國，外墻建筑保溫工程，遭到平凡的關心，巖棉復合板在外墻保溫建筑工程中，按照產物自身優點，盤據著保溫材料的半壁河山。

The thermal principle of external wall rock wool board quickly occupied the market of external wall thermal insulation materials - rock wool composite board and color steel composite board. Many enterprises choose more external wall thermal insulation materials during the renovation of factory buildings. In our country, the external wall building thermal insulation engineering, has been ordinary concern, rock wool composite board in the external wall thermal insulation building engineering, according to the product's own advantages, according to the half of the thermal insulation materials.

巖棉復合板，彩鋼復合板，被平凡應用外墻的保溫工程，這當中就必須提產物的熱工道理，和產物在多個行業的詳細使用。下面的文章將重 點從四個方面，對巖棉復合板的熱工道理實行論述:巖棉板，和同類彩鋼復合板的熱工道理解讀首先要熟悉的是，巖棉板作為建筑屋宇外墻外圍護結構隔熱材料分類、機理及使用。

Rock wool composite board and color steel composite board are commonly used in exterior wall thermal insulation engineering. In this case, the thermal principle of products and the detailed use of products in many industries must be mentioned. The following article will focus on four aspects to discuss the thermal principle of rock wool composite board: rock wool board and similar color steel composite board. The first thing to be familiar with is the classification, mechanism and use of rock wool board as thermal insulation material for building exterior wall.

在人類賴以生存的自然界中熱量所以傳導、對流和輻射三種方法傳導。根據傳熱的三種傳導機理和建筑屋宇外墻傳熱夏天是從室外向室內轉達、冬天是從室內向室外轉達的道理，不妨把建筑屋宇外墻外圍護結構隔熱相應的分紅間隔型隔熱、反射型隔熱、反射保溫型隔熱三種類別。

In the nature on which human beings depend for existence, there are three ways of heat conduction: conduction, convection and radiation. According to the three conduction mechanisms of heat transfer and the principle that the heat transfer of building exterior wall is transmitted from indoor to outdoor in summer and from indoor to outdoor in winter, it is advisable to classify the heat insulation of building exterior wall exterior envelope into three categories: partition type heat insulation, reflective type heat insulation and reflective type heat insulation.

說一說巖棉復合板作為建筑屋宇外墻外圍護結構隔熱保溫材料的熱工算計。

Let's talk about the thermal calculation of rock wool composite board as the thermal insulation material of building exterior wall.

經過算計充分論證了反射型和反射保溫型隔熱涂料擁有肯定的熱阻值R，且在涂膜抵達肯定的厚度后，熱阻值只與涂膜的反射率、蓄熱系數、表面溫度相關，與涂膜的厚度無關。

After calculation, it is fully demonstrated that reflective and reflective thermal insulation coatings have a certain thermal resistance value R, and after the film reaches a certain thickness, the thermal resistance value is only related to the reflectivity, heat storage coefficient and surface temperature of the film, and has nothing to do with the thickness of the film.

夏天反射率越高、表面溫度越低、熱阻值越大，冬天蓄熱系數越大、表面溫度越高，熱阻值越大。同時，經過熱工算計進一步闡通曉反射型和反射保溫型隔熱涂料的適用范圍。

In summer, the higher the reflectivity is, the lower the surface temperature is, and the greater the thermal resistance is. In winter, the greater the thermal storage coefficient is, the higher the surface temperature is, and the greater the thermal resistance is. At the same time, through thermal calculation, the application scope of reflective and reflective thermal insulation coatings is further explained.
