    水泥自流平施工的流程有哪些?

    一、基层处理:水泥之前的地表基层应当平整,干燥,坚固,没有灰尘和油污等。先用铲刀将地面上原有的石膏,油漆,水泥硬块等到突起物铲除,用高标号水泥拌107胶水垫平地表的坑洼及裂缝,做到地面平整要求;再用打磨机将整个地面打磨一遍,以确保地面没有突起和松动的地表。
    First, the basic treatment: cement before the surface should be flat, dry, solid, no dust and oil, etc.. First with the shovel will be ground on the original plaster, paint, cement lumps until projections to eradicate, high-grade cement mix 107 glue pad surface of potholes and cracks, do ground grading requirements; reoccupy burnish machine will be the ground burnish again, to ensure that the ground without protrusion and loose surface.
    然后将平整过的地面自然风干或用加热方式将其快速风干,使整个地面含水率不超过6%;再用扫帚将地面及各个角落清扫干净;用水平测量仪将地表上特别高出的地方结合粉笔将其圈出,再用打磨机在这局部高处进行精磨,使该处与其旁边地面厚度差不超过2.0毫米;后用吸尘器将所施工地面完整的吸几遍,务必清除地面微小颗粒。
    Then the flat ground natural air drying or heating the quick drying, the ground moisture content is less than 6%; use a broom to the ground and every corner of the clean; with level measuring instrument will surface particularly high with chalk will the circle, and then hit the mill in the local height for grinding, the premises and next to the thickness of the ground is less than 2.0 mm; finally use a vacuum cleaner will be the construction of a full ground of ceiling several times, be sure to remove the tiny particles in the surface.
    二、上界面剂:界面剂的目的是将地表基层与自流平水泥隔开,增强界面接着及封闭毛细孔,阻止自流平固化前水份渗透到基层中,造成自流平水化作用的不完整,同时防止基底湿气上升造成表面气孔。
    Second, the interface agent, interface agent is will be separated from the ground base and self leveling cement and enhance the interface then and closed pores, prevent self leveling before curing water penetration into the substrate, resulting in the role of artesian water incomplete, while preventing the substrate moisture caused by rising surface porosity.
    界面剂的加水比例一般为1:6,可以根据地面情况酌情加减。加水充分搅拌后用滚筒将界面剂均匀地涂在地表,至少涂刷界面剂2遍,且必须在遍干燥后涂刷第2遍。界面剂彻底干燥后可进行下一步施工。界面剂会极大的影响水泥自流平施工的整体质量。
    The water ratio of the interface agent is generally 1:6, can be modified according to the circumstances of the ground. Full mixing with water, the interface agent is evenly coated on the surface, at least 2 times, and must be applied in the first second times after drying. After the interface agent is completely dry, the next step can be carried out for the next step of construction. Interfacial agent can greatly affect the overall quality of the construction of cement self leveling.
    三、搅拌。在搅拌之前的准备工作一定要做充分,一组施工人员好备用多个水桶,其中一个用来搅拌,一个用来量水,一个用来盛水。量水的水桶一定要精确。按照建议的料水比例将自流平水泥材料和水搅拌均匀,要搅拌5分钟,静止3-5分钟,再搅拌2分钟。
    Three, stirring. In the mix before the preparatory work must be done well, a group of construction workers in the best alternate multiple buckets, one used to stir, to the amount of water, a to water containing. The amount of water in the bucket must be accurate. In accordance with the proposed material water ratio will be self leveling cement material and water mixing, stirring 5 minutes, rest 3-5 minutes, and then stirring for 2 minutes.
    四、流平与消泡。自流平水泥搅拌完成后,应尽快将桶内水泥倒入施工现场,如果做2mm厚度的自流平,可用自流平耙子来进行刮抹;如果要做3mm以上的自流平,可以用自流平大抹刀来做。自流平在地上刮抹之后,应尽快用消泡滚进行放气处理,刮抹和消泡施工人员必须穿上钉鞋。自流平的施工是边往后撤退,注意每桶自流平水泥之间的高低落差
    Four, flow flat and eliminate bubbles. Self leveling cement mixing is completed, should be as soon as the barrel of cement into the construction site, if the thickness of 2mm self levelling can be self leveling rake to wipe scrape; if you want to do more than 3mm of self leveling can with self leveling large spatula to do. Self leveling the ground wiped after, should as soon as possible with defoaming roll deflated treatment, blows wipes and defoaming construction personnel must wear the spikes. Self leveling construction is the side to retreat, pay attention to the height difference between the level of cement per barrel of a barrel
