抹面砂漿要求具有良好的和易性,容易抹成均勻平整的薄層,便于施工。還應有較高的黏結力,砂漿層應能與底面黏結牢固,長期不致開裂或脫落。處于潮濕環境或易受外力作用部位(如地面和墻裙等),還應具有較高的耐水性和強度。那么抹面砂漿都有什么作用?
The plastering mortar is required to have good workability, easy to be plastered into a uniform and flat thin layer, which is convenient for construction. The mortar layer should be able to bond firmly with the bottom surface without cracking or falling off for a long time. It should also have high water resistance and strength when it is in humid environment or easily affected by external force (such as floor and skirting). What is the function of plastering mortar?
在施工中,抹面砂漿常分兩層或三層進行施工,底層砂漿的作用是使砂漿與基層能牢固地粘結,應有良好的保水性。中層主要是為了找平,有時可省去不做。
In the construction, the plastering mortar is often divided into two or three layers for construction. The function of the bottom layer mortar is to make the mortar firmly bond with the base, and it should have good water retention. The middle level is mainly for leveling, sometimes it can be omitted.
面層主要為了獲得平整、光潔地表面效果。其主要作用是施工使用前和凝結硬化前,保證砂漿在施工時間內砂漿中有足夠的水分,提供良好的施工性。另外一個就是上墻后不會很容易就被基層快速吸收,導致砂漿中的膠凝材料沒有充足的水分進行水化反應,從而影響自身的性能。
The main purpose of the surface course is to obtain a smooth and smooth surface. Its main function is to ensure that there is enough water in the mortar during the construction period before the construction and before the setting and hardening, so as to provide good constructability. The other is that it is not easy to be absorbed by the base quickly after it is put on the wall, which leads to that the cementitious material in the mortar does not have enough water for hydration reaction, thus affecting its own performance.
抹面砂漿主要用于苯薄抹灰保溫系統中保溫層外的抗裂保護層,亦被稱為聚合物抹面抗裂砂漿。抹面砂漿應用與基面牢固地粘合,因此要求砂漿應有良好的和易性及較高的粘結力。
Plastering mortar is mainly used as crack resistant protective layer outside insulation layer in benzene thin plastering insulation system, also known as polymer plastering crack resistant mortar. The plastering mortar should be firmly bonded with the base surface, so the mortar should have good workability and high adhesion.
