Baotou partition board To share with you: thermal insulation material refers to a system composed of a single thermal insulation material and other auxiliary materials, which is called system thermal insulation material. At present, there are the following insulation system materials:
External wall thermal insulation system: Baotou GRC Foamed polystyrene board (or extruded polystyrene board) alkali resistant glass fiber mesh high polymer mortar, such as external wall thermal insulation system, external thermal insulation system of Beijing Zhongjian Hospital, Preswitt thermal insulation system, etc;
External insulation system items to be tested:
Heat exchange coefficient After the thermal insulation material of the system is combined with the main body, the thermal insulation effect will change due to the impact of construction quality and environmental temperature and humidity. Field test should be carried out to grasp its actual effect. According to JGJ26-95 of the Ministry of Construction and the indicators specified in the Code for Energy Conservation and Thermal Engineering Design of Civil Buildings in various places, it shall not be lower than its limit value; Baotou EP is waterproof, cold resistant, weather resistant, impact resistant and wind pressure resistant: as an external wall thermal insulation material, its finish is in direct contact with the external environment, and must resist the invasion of rain, freezing and thawing, impact, strong wind and other adverse factors.
The tensile strength of alkali resistant glass fiber mesh matching the external insulation system shall be greater than 200N/cm, and the tensile strength after alkali resistance shall not be less than 150 ≥ N/cm; The 7-day tensile bond strength of adhesive shall be greater than 1Mpa, and the tensile bond strength after water resistance and freeze-thaw resistance shall be greater than 0.9Mpa.
Internal thermal insulation system: there is foam polystyrene board (or extruded polystyrene board) paper faced gypsum board; GRC Thermal insulation board (blasted polystyrene board and cement mortar composite); Rock wool sandwich insulation board; Reinforced cement polystyrene insulation board, etc.
