界面劑在自流平水泥施工中有什么作用?
界面劑在自流平水泥施工中有什么作用?界面劑是在攤鋪水泥自流平之前需要對基礎(chǔ)地面進(jìn)行封閉和增加附著力不可缺少的輔助材料,其實(shí)是攤鋪任何水泥自流平都需要的配套材料。如果沒有界面劑,在混凝土地面上施工水泥自流平會出現(xiàn)以下情況,在混凝土地面上,由于基礎(chǔ)地面的吸水作用,導(dǎo)致水泥自流平水量損失過快,水泥自流平漿體無法在地面上正常自動流淌,漿體快速稠化無法攤開。如果界面劑材料的不合格,無法封閉混凝土表面的毛細(xì)孔,就會導(dǎo)致施工后水泥自流平表面出現(xiàn)許多的火山孔,極度影響水泥自流平的表面效果。這種現(xiàn)象對上面鋪貼PVC塑膠地板的水泥自流平也許影響不大,但是,對于彩色水泥自流平來說客戶是無法接受的,屬于施工的質(zhì)量問題,必須重新施工。另外在瓷磚面上做水泥自流平對界面劑要求更高,主要是要求界面劑要有很強(qiáng)的粘接力。一般界面劑是一種水性的環(huán)保乳液,應(yīng)該注意的是并不是所有的乳液都可以做水泥自流平的界面劑,界面劑的主要指標(biāo)應(yīng)該是具有很好的滲透封閉性及很強(qiáng)的粘接性,如果隨意使用界面劑,很有可能導(dǎo)致火山孔的出現(xiàn),嚴(yán)重的會開裂脫層。建議做水泥自流平,尤其是彩色水泥自流平最好選用廠家配套的界面劑,千萬不要因小失大。
目前,也有廠家建議用水性環(huán)氧撒砂的方法來代替界面劑,這也是一種方法,考慮到環(huán)保的因素,建議在商用場合的水泥自流平,盡量用水性環(huán)保的乳液界面劑,在工廠,停車場,倉庫的水泥自流平,可以使用環(huán)氧拋砂的方式。

What role does the interface agent play in the construction of self-leveling cement? The interface agent is an indispensable auxiliary material that needs to be closed to the ground and increase adhesion before paving cement self-leveling. In fact, it is an auxiliary material required for paving any cement self-leveling. If there is no interfacial agent, the following situation will occur in the construction of cement self-leveling on the concrete ground. On the concrete ground, due to the water absorption of the foundation ground, the amount of cement self-leveling water is lost too fast, and the cement self-leveling slurry cannot be automatically normal on the ground Flowing, the slurry thickens quickly and cannot be spread out. If the interface agent material is unqualified and the capillary pores on the concrete surface cannot be closed, many volcanic pores will appear on the cement self-leveling surface after construction, which greatly affects the surface effect of the cement self-leveling. This phenomenon may have little effect on the self-leveling of the cement on which the PVC plastic floor is laid. However, for the self-leveling of colored cement, the customer is unacceptable. It is a quality problem of construction and must be re-constructed. In addition, the self-leveling of cement on the tile surface requires higher interface agent, which mainly requires the interface agent to have strong adhesion. The general interface agent is a water-based environmentally friendly emulsion. It should be noted that not all emulsions can be used as cement self-leveling interface agents. The main indicators of the interface agent should be good penetration sealing and strong adhesion. If the interface agent is used arbitrarily, it is likely to cause the appearance of volcanic holes and severe cracking and delamination. It is recommended to do cement self-leveling, especially for color cement self-leveling. It is best to use the interface agent provided by the manufacturer. Don't lose it because of small.
At present, some manufacturers suggest to use water-based epoxy sand to replace the interface agent. This is also a method. Considering the environmental protection factors, it is recommended to self-level the cement in commercial occasions and try to use water-based environmental protection emulsion interface agent. In factories, parking lots, and warehouses, the cement is self-leveling, and epoxy sandblasting can be used.
