挤塑板保温层开裂的原因

1、石墨挤塑板虽然有非常好的保温防水性,但由于其强度较高,变形应力较大,表面光滑、疏水难以吸收,粘结保温板的胶粘剂跟墙体的粘贴附着性差等原因必然出现较为严重的质量事故。
1, although there is a graphite extruded board very good insulation and waterproof, but because of its high strength, high stress deformation, smooth surface and hydrophobic bonding to absorption, insulation board with adhesive paste wall adhesion is inevitable because of poor quality accidents are more serious.

2、石墨挤塑板比膨胀聚苯板的密度大、强度高,由于自身变形及温差变形而产生的变形应力也大,相对于每条板缝来说,相邻两块板自身的应力变化是反向的,对板缝处进行挤或拉,造成板缝处开裂、渗水、透寒、久而久之造成耐候性附着性下降会产生外保温系统的剥离、脱落,甚至导致外保温系统出现崩溃。

2, the graphite extruded plate than expanded polystyrene board of high density, high strength, deformation due to its deformation and temperature deformation stress is also large, with respect to each seam, two adjacent plate its stress change is reverse, the slab joints of squeezing or pulling, causing cracking, seepage, and slab joints through the cold, in the course of time caused by weathering adhesion drops produce peeling, external thermal insulation system off, and even lead to the collapse of external thermal insulation system.
3、石墨挤塑板具有小的导热系数,为0.029W/(m·k),而抗裂砂浆的导热系数为0.93W/(m·k),两层材料的导热系数差了32倍,比聚苯板与抗裂砂浆的导热系数相差大,因此容易产生裂缝。
3, the coefficient of thermal conductivity of graphite extruded plate has a smaller, 0.029W/ (M - K), and the thermal conductivity of the mortar is 0.93W/ (M - K), the thermal conductivity of two layers of material difference 32 times greater than the thermal conductivity of polystyrene board and the mortar is therefore more prone to crack.
