    自流平水泥使用中的四大要点
    来源:http://www.jndmzp.com   时间:2016-1-15 16:36:52
    1自流平水泥在施工现场按照生产商的要求加入适量的水,即可容易地进行搅拌和施工、准确的水量是达到正确的材料性能的关键。很多性能上的损害都是由于拌合水过量造成的.
    1 self leveling cement in the construction site in accordance with the requirements of the manufacturer to join the right amount of water, you can easily mix and construction, accurate amount of water is the key to achieve the correct performance of the material. Many properties are due to the damage caused by excessive mixing water.
    2自流平水泥是一种低黏度的砂浆,浇注在找平层上面,使用馒刀和带刺的消泡滚筒均匀地摊开并流平。自流平砂浆应在数小时内硬化,具有一定的一天强度,以允一天后在上面行走。终硬化的砂浆应提供一个均匀、坚硬、平整和光滑的表面,在粘贴面层(覆盖层)付料之前残余水分应小于2%。目前与自流平砂浆常用的配套面层装饰材料为PVC地板.
    2 self leveling cement is a low viscosity of the mortar, pouring in the leveling layer above using trowel and prickly defoaming drum evenly stall and leveling. Self leveling mortar should be hardened in a few hours, with a certain intensity of one day, to allow a day to walk on the top. The final hardened mortar should provide a uniform, hard, flat and smooth surface, and the residual moisture content should be less than 2% before the adhesive surface layer (covering layer). Currently with self leveling mortar the most commonly used supporting surface layer decoration materials for the PVC floor.
    3目前使用的是对环境友好的水基胶来粘贴PVC地板,因此自流平砂浆必须具有一定的吸收性,以便水基胶尽早地产生粘结力。这一点对于获得理想的工作性和对面层材料(终饰覆盖层)的终粘结性是非常重要的。
    3 currently in use is of the environmental friendly water-based glue to paste PVC floor, so self leveling mortar must have certain absorption to water-based glue early produced cohesive force. This is very important for achieving the ultimate bond between the ideal work and the material (final).
    4因要求自流平水泥有特殊性能——快硬、快于和低收缩性,若全部使用硅酸盐水泥作胶凝材料,砂浆干燥速度不够快,达到可以铺设地面的程度所需的时间过长。此外,还可出现现较大的收缩。
    4 due to the requirement of self leveling cement with special properties, hard and fast, fast and low shrinkage, if all of the use of Portland cement as the cementing material, mortar drying speed is not fast enough to lay the ground for a long time. In addition, there may be a larger contraction.
