现在挤塑板表现密度情况影响

1、导热性(W/m.k):稳定状态下1米厚的物体,两侧表面温差为1K,1小时内通过1平方面积的传热量。检测标准应该在0.03W/m.k以下。(我们在生产前期对市面上的地暖铺装的挤塑板做了摸底调查,一般建材市场2公分灰绿色挤塑板导热系数在0.04—0.07W/m.k之间)
1, thermal conductivity (W/m.k): stable state of 1 meters of the object, the temperature difference between the two sides of the 1K, 1 hours through the 1 square area of heat transfer. Testing standards should be below 0.03W/m.k. (we do a thorough investigation, on the pavement on the market to warm extrusion plate production in the general building materials market 2 cm gray green extruded plate thermal conductivity between 0.04 - 0.07W/m.k)

2、表观密度(kg/m3):我们俗称的容重,就是自然状态下,单位体积的重量。因为重量和干燥度有直接影响,一般要用库存30天以上的产品。

2, apparent density (kg/m3): we commonly known as the bulk density, is the natural state, the weight of unit volume. Because the weight and dryness have a direct impact, the general need to use more than 30 days of product inventory.
3、压缩强度(MPa):我们经常说的抗压强度,是指10%变形下的压缩反应。检测标准应该在200-500MPa之间
3, compressive strength (MPa): we often say that the compressive strength is the compression of the 10% deformation of the reaction. Testing standards should be between 200-500MPa
4、氧指数:其实就是我们常说的阻燃性。是通过增加添加调整维持燃烧的最小氧气密度,以我个人粗浅理解是燃烧时添加的某种物质会马上形成隔离层,杜绝氧气从而达到减少燃烧面积。检验。
4, oxygen index: in fact, we often say that the flame retardant. Is to maintain the minimum oxygen density by adding adjustment to maintain the minimum oxygen density, in my personal superficial understanding of the combustion is to add some kind of material will immediately form a separate layer, to eliminate oxygen to reduce the burning area. Inspection.
