    外墙外保温系统是建筑物最外表面的工程构造,长时间受风、雨、雪、冻、热、重力剪切荷载、火、震、冲击等各种外力的影响,在不同气候条件对外墙外保温工程的破坏程度有所不同。
  因此在不同的气候区域须有不同的技术要求和侧重条件。在沿海多风多雨地区应用粘贴保温板且有空腔的外墙外保温系统技术,因拼缝、有空腔等技术特征,使保温工程产生表面裂纹、保温层脱落、面砖脱落、墙体渗水等可能性增加。
  在严寒、寒冷地区应用粘贴保温板且有空腔的外墙外保温系统技术,一旦表面产生裂纹,如果出现渗水将增强热桥效应,因冻胀而产生脱落,最终会造成室内发霉、结露、返霜等问题。
  在昼夜温差大、气候干燥的地区应用柔性抗裂能力较差的外墙外保温系统技术,易发生冷热应力造成持续性裂纹,进而产生继发性质量事故。


   Exterior insulation system is the most outer surface engineering construction, building a long time by wind, rain, snow, cold, heat, gravity shear load, fire, earthquake, impact and the influence of the external force in different climate conditions of external wall thermal insulation engineering damage is different.西宁保温材料|西宁防水材料|青海保温防水材料|西宁硅酸盐|青海硅酸盐
   So in different climate regions have different technical requirements and focusing on the conditions. Application in coastal windy and rainy region free paste insulation board and cavity technology of exterior insulation system, by the technical features of flat-fell seam, free cavity, the surface crack, insulation heat preservation engineering fall off, the more likely such as brick, wall ooze water.西宁保温材料|西宁防水材料|青海保温防水材料|西宁硅酸盐|青海硅酸盐
    In cold, cold area application free paste insulation board and cavity technology of exterior insulation system, once the surface crack, if there is a water seepage effect would enhance the thermal bridge, the loss due to frost heave, will eventually cause indoor mildewy, condensation, back to the frost, and other issues.西宁保温材料|西宁防水材料|青海保温防水材料|西宁硅酸盐|青海硅酸盐
    In day and night temperature difference big, dry climate region of application of flexible anti-cracking ability poor exterior insulation system, prone to heat and cold stress caused by continuous crack, thus producing secondary quality accident.
