石膏砌块的优点体现在哪里?

  石膏砌块性能优异

  Excellent performance of gypsum block
  1. 石膏砌块与其他墙体材料尤其是传统实心粘土砖相比具有以下优点:
  1. Compared with other wall materials, especially traditional solid clay brick, gypsum block has the following advantages:
  石膏的耐火性能是混凝土的5倍。石膏砌块具有比普通纸石膏板更高的耐火性能。1998年,我国颁布了《建筑材料燃烧性能分类方法》和《建筑材料可燃性试验方法》,将石膏制品分类为不可燃产品。1995年《建筑室内装饰设计防火规范》实施后,石膏墙板产品销量迅速增长。在德国,石膏砌块是DIN4102规定的a1级不燃建筑材料。石膏砌块隔墙厚度大于80mm为防火级(防火级f180-a);以上100mm石膏板隔墙属于高耐火等级(防火等级f180-a),日本建设省房管局规定,凡使用国库补贴的建筑,凡发生火灾时,非可燃材料必须用石膏板制成天花板和内墙防火板。
  The fire resistance of gypsum is five times that of concrete. Gypsum block has higher fire resistance than ordinary paper gypsum board. In 1998, China promulgated "Classification Method for Combustibility of Building Materials" and "Test Method for Combustibility of Building Materials", classifying gypsum products as non-combustible products. After the implementation of Fire Protection Code for Building Interior Decoration Design in 1995, sales of gypsum wallboard products increased rapidly. In Germany, gypsum blocks are class A1 non-combustible building materials specified in DIN4102. The thickness of gypsum block partition wall is more than 80 mm, which is fire-proof grade (fire-proof grade f180-a). The above 100 mm gypsum board partition wall belongs to high fire-proof grade (fire-proof grade f180-a). The Ministry of Construction and Housing Administration of Japan stipulates that all buildings subsidized by the State Treasury must be made of non-combustible materials into ceilings and interior wall fire-proof panels in case of fire.
  此外,由于两种水石膏在火灾高温状态下释放水分,其含量高达21%。如果墙体为80mm厚的石膏砌块墙,每平方米火灾燃烧时应蒸发约15kg的水,墙体可进一步升温。一般情况下,1kg结晶水需要126KJ左右的热量。40平方米的办公室相当于1t的水蒸发,这将消耗大量的热量。其他非石膏墙体材料则没有这种特性。
  In addition, because the two kinds of water gypsum release water at high temperature in fire, the content of water gypsum is as high as 21%. If the wall is 80 mm thick gypsum block wall, about 15 kg of water should be evaporated per square meter when the fire burns, and the wall can be further warmed up. Generally, 1 kg crystalline water needs about 126 KJ of heat. 40 square meters of office is equivalent to 1 ton of water evaporation, which will consume a lot of heat. Other non-gypsum wall materials do not have this characteristic.
  2、具有良好的绝缘和隔音特性
  2. Good insulation and sound insulation
  1厘米厚石膏层的隔热性能相当于3厘米厚的砖层、4厘米厚的灰浆灰泥或5厘米厚的混凝土房屋的隔热性能。
  The thermal insulation performance of 1 cm thick gypsum layer is equivalent to that of 3 cm thick brick layer, 4 cm thick mortar or 5 cm thick concrete house.

  当普通外墙砖厚度为370mm时,传热系数为1.34kcal /M2?H ?如果采用200mm厚石膏板墙体,传热系数为0.17Kcal/M2?H ?℃时,节能60%,一般80mm厚石膏砌块相当于240mm厚实心砖的保温能力。
  When the thickness of ordinary exterior wall brick is 370 mm, the heat transfer coefficient is 1.34 kcal/M2?H? If 200 mm thick gypsum board wall is adopted, the heat transfer coefficient is 0.17 Kcal/M2?H????? C, the energy saving is 60%, and the heat preservation capacity of 80 mm thick gypsum block is equivalent to that of 240 mm thick solid brick.
  此外,以100mm厚石膏砌块墙体为例,其隔声效果达到36-38db,这是其他同类型、同厚度建筑材料难以达到的。脱硫石膏粉空心砌块的隔声价值,尤其是低频隔声价值虽然有所降低,但仍能满足隔声要求。在石膏砌块中加入膨胀珍珠岩、陶粒等轻质集合体,或发泡石膏浆,或采用空腔结构和吸声材料等,可提高砌块的保温隔声性能。
  In addition, taking 100 mm thick gypsum block wall as an example, its sound insulation effect reaches 36-38 db, which is difficult to achieve by other similar building materials with the same thickness. Desulfurization gypsum powder hollow block sound insulation value, especially low-frequency sound insulation value, although reduced, but still can meet the requirements of sound insulation. Adding light aggregates such as expanded perlite and ceramsite, or foaming gypsum slurry, or using cavity structure and sound absorbing materials in gypsum blocks can improve the insulation and sound insulation performance of the blocks.
  3、墙体较轻,抗冲击性好
  3. The wall is lighter and has good impact resistance.
  双石膏粘土固体砖,例如,半砖墙296重㎏/㎡,一堵砖墙的重量524㎏/㎡,和不同的固体抹石膏砌块墙,大约72㎏/㎡80毫米厚,100毫米厚约90㎏/㎡,粘土实心砖的1/3重量墙- 1/4。
  Double gypsum clay solid brick, for example, half brick wall 296 heavy /, a brick wall weight 524 /, and different solid plaster block walls, about 72 / 80 mm thick, 100 mm thick about 90 /, clay solid brick 1/3 weight wall - 1/4.
  由此可见,具有优良特性的石膏砌块能够很好地满足我们的发展需求,这类环保节能产品值得我们的信赖和开发是很重要的。
  Therefore, gypsum blocks with excellent characteristics can well meet our development needs. It is very important for us to trust and develop this kind of environmental protection and energy saving products.
