为什么济南抹面砂浆长期处于潮湿环境而不开裂

来源:https://www.jnfhjc.com 日期:2020-03-11 发布人:admin

  由于济南抹面砂浆容易平铺成均匀的薄层,施工方便。也应该有更高的结合力,砂浆层应该能够与坚定的底部,长期不开裂或脱落。在潮湿环境或受外力作用(如地面和护墙板等),还是应该有更高的耐水性和强度。

  Because Jinan plastering mortar is easy to spread into a uniform thin layer, the construction is convenient. There should also be a higher binding force, and the mortar layer should be able to work with a firm bottom for a long time without cracking or falling off. In the humid environment or under the action of external forces (such as the ground and dado, etc.), it should have higher water resistance and strength.
  该抹面砂浆主要用于苯薄抹灰保温系统保温层外的防裂保护层,又称聚合物抹灰防裂砂浆。抹灰灰浆用于与基层表面牢固粘结,要求灰浆具有良好的和易性和较高的粘结力。灰浆的组成与砌体灰浆基本相同,但为了防止灰浆开裂,有时需要加入一些纤维材料(如纸、麻、有机纤维等);为了加强某些功能,需要添加一些特殊的骨料(如陶瓷砂、膨胀珍珠岩等)。
济南抹面砂浆
  The plaster mortar is mainly used for the anti crack protective layer outside the thermal insulation layer of the benzene thin plaster insulation system, also known as polymer plaster anti crack mortar. Plastering mortar is used to firmly bond with the base surface, which requires good workability and high adhesion. The composition of mortar is basically the same as that of masonry mortar, but in order to prevent mortar cracking, some fiber materials (such as paper, hemp, organic fiber, etc.) need to be added sometimes; in order to strengthen some functions, some special aggregates (such as ceramic sand, expanded perlite, etc.) need to be added.
  特点:
  Characteristic:
  与砌筑砂浆相比,河南石膏砂浆具有以下特点:
  Compared with masonry mortar, Henan gypsum mortar has the following characteristics:
  抹灰层不承受荷载;
  The plastering layer shall not bear the load;(2)抹灰层与基层应有足够的粘结强度,使其在施工或长期自重与环境的作用下不脱落、不开裂;表面层大多为薄层,并分层涂抹,要求表面层平整、光滑、干净、细致、美观;用于干燥环境,大面积暴露于空气中。
  (2) The plastering layer and the base course shall have sufficient bonding strength to prevent them from falling off and cracking under the effect of construction or long-term self weight and environment; the surface layer is mostly thin layer, which shall be applied layer by layer, and the surface layer shall be flat, smooth, clean, meticulous and beautiful; it is used in dry environment, with large surface exposed to the air.

  Functions:
  济南抹面砂浆通常分为两层或三层施工:
  Jinan plastering mortar is usually divided into two or three layers of Construction:
  (1)底层砂浆的作用是使砂浆与基层能牢固粘结,应具有良好的保水性能。
  (1) The function of the bottom mortar is to make the mortar and the base course bond firmly, which should have good water retention performance.
  (2)中层主要是用来找平的,有时可以省略不做。
  (2) The middle layer is mainly used for leveling, sometimes it can be omitted.
  (3)表面层主要是为了获得光滑和光滑的表面效果。
  (3) The main purpose of surface layer is to obtain smooth and smooth surface effect.
