了解外墙vnsc3775威尼斯城官网的热工原理

发布时间:2021-06-28 来源:/

外墙vnsc3775威尼斯城官网的热工原理,迅速侵占外墙保温材料商场--岩棉复合板、彩钢复合板,这是很多企业在对厂房实行改建时间,挑选多的外墙保温材料。在我国,外墙建筑保温工程,遭到平凡的关心,岩棉复合板在外墙保温建筑工程中,按照产物自身优点,盘据着保温材料的半壁河山。

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.

岩棉复合板,彩钢复合板,被平凡应用外墙的保温工程,这当中就必须提产物的热工道理,和产物在多个行业的详细使用。下面的文章将重 点从四个方面,对岩棉复合板的热工道理实行论述:vnsc3775威尼斯城官网,和同类彩钢复合板的热工道理解读首先要熟悉的是,vnsc3775威尼斯城官网作为建筑屋宇外墙外围护结构隔热材料分类、机理及使用。

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.

在人类赖以生存的自然界中热量所以传导、对流和辐射三种方法传导。根据传热的三种传导机理和建筑屋宇外墙传热夏天是从室外向室内转达、冬天是从室内向室外转达的道理,不妨把建筑屋宇外墙外围护结构隔热相应的分红间隔型隔热、反射型隔热、反射保温型隔热三种类别。

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.

说一说岩棉复合板作为建筑屋宇外墙外围护结构隔热保温材料的热工算计。

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

经过算计充分论证了反射型和反射保温型隔热涂料拥有肯定的热阻值R,且在涂膜抵达肯定的厚度后,热阻值只与涂膜的反射率、蓄热系数、表面温度相关,与涂膜的厚度无关。

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、表面温度越低、热阻值越大,冬天蓄热系数越大、表面温度越高,热阻值越大。同时,经过热工算计进一步阐通晓反射型和反射保温型隔热涂料的适用范围。

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.
