决定保温装饰一体板好坏的因素
一、导热系数。保温装饰一体板传递热能的巨细参数是反应资料导热的才能,导热率与资料别的的物理功用有着较大联系,比方密度和含水率,这些抖与导热性密切相关,保温装饰一体板的导热率还和内部构造有联系,与保温层尺度的巨细也有着不行忽略的联系。
I. thermal conductivity. Heat preservation to decorate a whole plate of transfer heat to intrusive parameter is the response data of thermal conductivity, thermal conductivity and other physical function has a larger contact information, such as density and moisture content, the shake is closely related to the thermal conductivity, heat preservation to decorate a whole plate of the thermal conductivity and the internal structure also have a contact, and the thermal insulation layer of intrusive has not ignored.
二、容重。也就是密度,在最佳的容重值下,保温装饰一体板才具有较小的导热率以及较好的保温作用,在施工的过程中,咱们为了节约能源,削减保管的构造荷重需求选用容量较小的保温装饰一体板。软质和半硬质的资料容重不得大于150kg/m3,硬质资料的容重不得大于220kg/m3.
2. Density, under the best density value, the heat preservation to decorate a whole plate only has a smaller thermal conductivity and good heat preservation effect, in the process of construction, we in order to save energy, cut takes care of the load on the structure of the demand to choose smaller heat preservation decoration plate. The bulk density of soft and semi-rigid materials shall not be greater than 150kg/m3. The bulk density of hard data shall not be greater than 220kg/m3.
三、抗压强度和抗折强度。经过国家的规定,硬质成品抗压强度不得小于0.3MPa,所以在关于软质、半硬质及松懈状绝热资料的抗压强度未作规定。抗折强度是指资料在遭到曲折负荷作用下破坏时,单位面积上所受的力偶矩。
3. Compressive strength and folding strength. After the national regulation, the compressive strength of hard finished products should not be less than 0.3 MPa, so the compressive strength of the soft, semi-rigid and slack adiabatic data is not specified. The flexural strength refers to the force moment in the unit area when the data is destroyed under the action of tortuous load.
