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.

　　濟南抹面砂漿廠家:無機保溫砂漿的干密度應為多少？

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

　　一、概念首先我們要理解干粉容重和涂布率兩個根本概念：

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

　　1.干粉容重: 單位體積的重量, 普通表達為 公斤/立方米,是保溫資料的重要指標,它的數(shù)據(jù)決議了資料的保溫性能. 對市場銷售的保溫砂漿,其干容嚴重概分為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,第二種分別滿足規(guī)程做為墻面和空中的保溫材資料的技術(shù)參數(shù)請求。

　　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:在墻體上完成特定厚度的施工涂層需求的干粉資料的重量, 由于保溫資料的熱阻R=δ/λ,其中δ為保溫資料厚度，因而在導熱系數(shù)一定時，厚度直接決議保溫效果，這就像厚棉衣比薄棉衣保溫效果更好一樣，施工圖普通都嚴厲規(guī)則保溫層的施工厚度以保證保溫效果．由于資料的容重不同，因而完成相應施工厚度所消耗的保溫資料重量就是涂布率。

　　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.
