薄层抹面砂浆的技术要求有哪些?

来源: 日期:2019-04-11 发布人:admin

  薄层抹灰砂浆主要用于平整度高的墙体抹灰。基层平整度高,且结构和建筑也允许或者要求使用薄层抹灰的话,那么就可采用薄层抹灰。薄层抹灰层的厚度一般在3~5mm,大不超过8mm。薄层抹灰厚度薄,对砂浆的要求就与普通抹灰砂浆(抹灰层每层厚度7~9m,总厚度20mm)有很大的区别。首先,薄层抹灰厚度仅3mm,它对保水性要求就非常高。

  Thin layer plastering mortar is mainly used for plastering walls with high smoothness. If the base level is high, and the structure and building permit or require the use of thin layer plastering, then thin layer plastering can be used. The thickness of thin plastering layer is generally 3-5 mm, the maximum is not more than 8 mm. Thin layer plastering thickness is thin, the requirements for mortar are very different from ordinary plastering mortar (plastering layer thickness 7-9 m, total thickness 20 mm). First of all, the thickness of thin layer plastering is only 3 mm, which requires very high water retention.

  Thin layer plastering mortar is mainly used for plastering walls with high smoothness. If the base level is high, and the structure and building permit or require the use of thin layer plastering, then thin layer plastering can be used. The thickness of thin plastering layer is generally 3-5 mm, the maximum is not more than 8 mm. Thin layer plastering thickness is thin, the requirements for mortar are very different from ordinary plastering mortar (plastering layer thickness 7-9 m, total thickness 20 mm). Firstly, the thickness of thin layer plastering is only 3mm, which requires very high water retention requirements. To ensure that the moisture in mortar is not absorbed by the base or evaporated into the atmosphere, the water retention is generally required to be above 98%. Secondly, thin layer plastering mortar requires smaller aggregate size, generally not more than 1mm, to ensure that the gelling material is wrapped on the aggregate surface. Thirdly, thin layer plastering mortar not only contains inorganic materials such as cement base. Cementing materials should also contain Organic cementitious materials, such as various resins, emulsions, etc. Finally, the thin layer plastering mortar should also have good crack resistance so as to ensure that the mortar does not produce cracks.
  目前,我国薄层抹灰砂浆主要用于外墙外保温的表面抗裂砂浆和蒸压加气混凝土砌块的薄层抹灰。
  At present, thin plastering mortar is mainly used for surface crack resistance mortar and thin plastering of autoclaved aerated concrete blocks for external wall insulation in China.
