    水泥基自流平砂浆施工时假如掌握欠好,也会呈现各种不行预知的问题,比方外表起粉、发花、气泡、针眼等,那么水泥基自流平砂浆在施工中应该注意哪些问题呢
    If the construction of cement-based self-leveling mortar is not well mastered, it will also present a variety of unpredictable problems, such as the appearance of powder, blooming, air bubbles, pinholes, etc., then what should be paid attention to in the construction of cement-based self-leveling mortar?
    1.起砂地上处理关于细微起砂的地上,施工前应先打扫洁净地上,用吸尘器铲除尘埃,涂刷两遍界面剂,假如底层吸水率过大时需要多涂刷几遍,等界面剂彻底枯燥后再进行自流平施工。关于起砂严峻的地上,应用打磨机将起砂的地上打磨,将外表的疏松层打磨掉,再用环氧资料对地上进行加固处理,然后才干进行水泥基自流平砂浆的施工。
    1. To deal with the fine sand on the ground, clean the ground before construction, use a vacuum cleaner to remove dust, brush twice the interface agent, if the bottom water absorption rate is too high, need to brush several times, such as the interface agent thoroughly dry before self-leveling construction. As for the grinding ground, the grinding machine is used to grind the grinding ground, to grind the loose layer off the surface, and then to reinforce the ground with epoxy materials, and then to carry out the construction of cement-based self-leveling mortar.
    2.发花,外表起粉问题解决,为了防止水泥基自流平发花、外表起粉等问题的发生,水泥基自流平砂浆施工时应严格操控加水量,施工时应先确定规范的加水量,并设专人称量加水,确保资料在整个施工进程中加水量共同,一起也要确保每桶资料拌和时刻大致相当,确保拌和充沛和均匀。

    2. The problem of flowering and powdering on the surface is solved. In order to prevent the occurrence of flowering and powdering on the surface of cement-based self-leveling mortar, the amount of water added should be strictly controlled during the construction of cement-based self-leveling mortar. It is also necessary to ensure that the mixing time is approximately equal to each barrel, ensuring that the mixing is abundant and even.

    3.底层裂纹处理,关于底层较宽的裂缝,应剔成深“V”形槽,然后整理洁净槽内的尘埃,并涂刷界面剂以进步修补资料与底层的粘接,修补可以用专用的低缩短快硬修补砂浆,也可以用水泥基自流平砂浆干粉加少数水将裂缝填实,抹平。
    3. The bottom crack treatment, regarding the bottom wider crack, should reject the deep "V" shaped groove, then clean up the dust in the groove, and brush the interface agent to improve the repair data and the bottom bonding, repair can be used special low-cut quick-hardening repair mortar, can also be used cement-based self-leveling mortar dry powder with a small amount of water to fill the crack. Smooth and smooth.
    4.气泡针眼的操控,气泡、针眼是水泥基自流平砂浆常见的问题,施工中为了尽量防止气泡、针眼的呈现,应该依据底层的实际情况,涂刷两遍界面剂,底层吸水率过大时应适当添加界面剂用量,界面剂涂刷有必要均匀,界面剂涂刷彻底枯燥后应以滴水不渗水为好。
    4. Bubble control, bubbles and pinholes are the most common problems of cement-based self-leveling mortar. In order to prevent the appearance of bubbles and pinholes as far as possible, the interface agent should be brushed twice according to the actual situation of the bottom layer. When the water absorption of the bottom layer is too high, the amount of the interface agent should be added properly. It is necessary to uniformly brush the interface agent. When the agent is thoroughly dry, it should be good for dripping water.
    往往一个细微的问题就决议工作的胜败,在水泥基自流平砂浆施工中也是相同,只要注意以上这些细节,才干得到一个高质量地坪。
    Often a minor issue on the decision of the success or failure of the work, in the construction of cement-based self-leveling mortar is the same, as long as the attention to these details, only to get a high-quality floor.
