Special cement mortar production process

Abstract

The invention discloses a special cement mortar production process, which relates to the technical field of building materials, and comprises the following steps: mortar proportioning, mixture stirring, fiber arrangement, mortar pouring, and maintenance molding. The staggered extrusion mechanism and the spiral extrusion piece are arranged on the mixing plant, the output ends of the two vibration motors drive the eccentric wheels to vibrate, and the two correspondingly arranged eccentric wheels drive the crank to swing in a reciprocating mode around the center rotation connecting position; the mixed fiber materials and the expanded and vitrified small balls in the mixing station are sucked out of the negative pressure material storage barrel through swinging of the crank, it is guaranteed that preparation and mixing are uniform and consistent, the expanded and vitrified small balls, attached to the spiral fiber materials, in the prepared special cement mortar can be filled into generated fine and dense tiny cracks when the temperature changes greatly, and therefore the good mixing effect is achieved. The heat insulation and sound insulation effects are improved, the thickness is small, multi-layer smearing is not needed, and materials are not wasted.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a special cement mortar production process. Background technique [0002] The mortar used in building construction is generally composed of various materials such as sand, cement and appropriate additives when necessary, mixed in a certain proportion. It is made by mixing inorganic cementitious material with fine aggregate and water in proportion, also known as mortar. For mortars used in special environments, special materials need to be added during the preparation process, and special production processes need to be matched. [0003] For areas with obvious temperature changes, or when there is a lot of rainwater attached to the side walls of buildings, the temperature changes are also more significant. In this case, thickening methods are generally used to reduce the impact of temperature changes during the application of mortar during construction. , but as a res...

Problems solved by technology

[0003] For areas with obvious temperature changes, or when there is a lot of rainwater attached to the side walls of buildings, the temperature changes are also more significant. In this case, thickening methods are generally used to reduce the impact of temperature changes during the application of mortar during construction. , but as a result, the amount of material application increases, and the waste phenomenon is serious. At the same time, the surface of the mortar near the outer layer often has internal and external cracks caused by temperature changes. The slight change in the internal structure will affect the heat insulation and sound insulation of the mortar layer.
