     很多人在選擇保溫材料作為外保溫主材時僅憑導熱系數或吸水率的高低作為評價依據,而實際上導熱系數是衡量保溫材料的保溫性能的一項指標,并且也是選擇保溫材料的重要參考項,但衡量保溫材料好壞的指標并非只是導熱系數這一項就能夠決定的,一定要參考以下幾項指標綜合判斷:

     
      1、吸水率:建筑保溫是為建筑穿上一件棉襖,這件棉襖除了要保溫外,還不能吸水。
     
      2、透氣性:透氣性這項技術指標是指水汽擴散阻力。如果外墻外保溫系統透氣性不好,水氣擴散受阻,一是阻礙墻體向外排濕,影響飾面涂料的顏色;二是產生應力,使涂膜鼓泡,脫落;三是導致墻身含濕量逐步增加,產生冷凝水富集,從而給墻體熱工、結構等性能帶來不利影響,四是即使外墻外保溫系統節能達標了,但卻造成室內空氣渾濁,不適合人居。
     
      3、粘結強度:反映判斷墻體保溫材料的粘結牢固程度,為減少和避免墻體保溫系統的空鼓.開裂和脫落現象,確保安全耐久性的使用功能。
     
      4、抗拉強度:保溫板要滿足一定的抗拉強度或撕裂強度。
     
      5、抗壓強度
     
      6、防火性能:防火性能會有相應的材料的防火性能級別,
     
      7、環保性
     
      8、使用壽命
     
      保溫材料的選擇可說是一項辛苦活兒,望朋友們能夠仔細考量篩選,一定不要盲目的選擇。了解詳細情況可以到我們的官方網站www.linsoo.cn了解。

    Many people choose thermal insulation materials as external thermal insulation main materials based on the thermal conductivity or water absorption rate as the evaluation basis, and in fact the thermal conductivity is an indicator of the thermal insulation performance of thermal insulation materials, and is also an important reference for selecting thermal insulation materials. item, However, the indicator for measuring the quality of thermal insulation materials is not only determined by the thermal conductivity factor, but must refer to the following indicators for comprehensive judgment:
    1, water absorption rate: building insulation is for the building wearing a cotton-padded jacket, this cotton-padded jacket in addition to insulation, but also can not absorb water.
    Permeability: Permeability This technical indicator refers to the diffusion resistance of water vapor. If the outer wall insulation system has poor air permeability and the water gas diffusion is blocked, the first is to prevent the wall from being wet and affect the color of the finish paint; The second is to produce stress, so that the coating drum bubble, fall off; The third is the gradual increase in the moisture content of the wall body, resulting in the enrichment of condensed water, which has a negative impact on the performance of the wall thermal engineering and structure. Fourth, even if the external insulation system of the outer wall is energy-saving, it has caused indoor air to become turbid. Not suitable for human settlements.
    3, bond strength: reflects the determination of the bond strength of Wall insulation materials, in order to reduce and avoid the wall insulation system air drum-cracking and shedding phenomenon to ensure the use of safety and durability.
    4, tensile strength: thermal insulation plate to meet a certain tensile strength or tear strength.
    5, compressive strength
    6, fire performance: fire performance will have the corresponding material fire performance level,
    7, environmental protection
    8, useful life
    The choice of thermal insulation materials can be said to be a hard work, hope that friends can carefully consider screening, must not blindly choose. For more information, please refer to our official website, www.linso.cn.
