With the issuance of document No. 65, rules, extinguishing performance of exterior wall thermal insulation data for civil buildings is grade A. At present, hollow glass beads thermal insulation data occupy most of the market in Chengdu. The price of hollow glass beads in the market has increased from 1800 yuan/ton to 2200 yuan/ton. Recently, many friends are asking about the bulk density of insulating hollow glass beads mortar. Now let's talk about the bulk density of insulating hollow glass beads mortar.

　　济南抹面砂浆厂家:无机保温砂浆的干密度应为多少？

　　Jinan plastering mortar manufacturer: What is the dry density of inorganic thermal insulation mortar?

　　一、概念首先我们要理解干粉容重和涂布率两个根本概念：

　　First, we need to understand the two basic concepts of dry powder bulk density and coating rate.

　　1.干粉容重: 单位体积的重量, 普通表达为 公斤/立方米,是保温资料的重要指标,它的数据决议了资料的保温性能. 对市场销售的保温砂浆,其干容严重概分为270公斤/立方米,320公斤/立方米,380公斤/立方米,420公斤/立方米,其中只要,第二种分别满足规程做为墙面和空中的保温材资料的技术参数请求。

　　1. Dry powder bulk density: the weight per unit volume, commonly expressed as kilogram/cubic meter, is an important index of thermal insulation data. Its data determine the thermal insulation performance of the data. For the thermal insulation mortar sold in the market, its dry capacity can be divided into 270 kg/cubic meter, 320 kg/cubic meter, 380 kg/cubic meter, 420 kg/cubic meter, of which only the first one is required. First, the second one satisfies the technical parameter requirements of the regulations as wall and air insulation materials respectively.

　　2.涂布率:在墙体上完成特定厚度的施工涂层需求的干粉资料的重量, 由于保温资料的热阻R=δ/λ,其中δ为保温资料厚度，因而在导热系数一定时，厚度直接决议保温效果，这就像厚棉衣比薄棉衣保温效果更好一样，施工图普通都严厉规则保温层的施工厚度以保证保温效果．由于资料的容重不同，因而完成相应施工厚度所消耗的保温资料重量就是涂布率。

　　2. Coating rate: The weight of dry powder material required to complete the construction coating with a specific thickness on the wall. Because the thermal resistance R of the insulation material is equal to delta/lambda, in which delta is the thickness of the insulation material, when the thermal conductivity is constant, the thickness directly decides the insulation effect, which is similar to that of thick cotton clothes, which is better than thin cotton clothes. Strictly regulate the construction thickness of thermal insulation layer to ensure the thermal insulation effect. Due to the different volume weight of data, the weight of thermal insulation material consumed to complete the corresponding construction thickness is the coating rate.

　　2. Performance Relation Table of Hollow Glass Bubble Thermal Insulation Mortar with Different Quality: Volume Weight (kg/m3) 270 320 360 420 Coating Rate (kg/m2.1 cm thickness) 33.64.04.67.
