Multi-dimensional variable-frequency vibration extrusion molding technology suitable for production of wallboards

Abstract

The invention discloses a multi-dimensional variable-frequency vibration extrusion molding technology suitable for the production of wallboards. The multi-dimensional variable-frequency vibration extrusion molding technology includes the following steps that raw materials are weighed, specifically, firstly, the raw materials are screened, suitable raw materials are selected, and then raw materialscomponents are weighed according to the proportions, and the raw material components are initially mixed and stirred; solid and liquid are matched, specifically, the solid raw material components andthe liquid raw material components are added in an extruder according to the specified proportions; and stirring and mixing are carried out, specifically, the solid raw material components and the liquid raw material components are fully stirred in the extruder until the mixing is uniform. After the wallboard raw materials are extruded into a mold, the mold is subjected to in-mold vibration, theraw materials in the mold are subjected to multi-dimensional variable-frequency vibration extrusion operations through the ways of low-frequency and low-pressure vibration, low-frequency and high-pressure vibration, high-frequency and low-pressure vibration and high-frequency and high-pressure vibration, the toughness of the produced wallboard is greatly increased, the uniform distribution of theraw materials inside the mold is ensured, and the quality of the produced wallboards is greatly improved.

Description

technical field [0001] The invention belongs to the field of wallboard production, in particular to a multi-dimensional frequency conversion vibration extrusion molding technology suitable for producing wallboards. Background technique [0002] In the existing life, with the continuous development of the construction industry, the requirements for the construction industry are also increasing. For the brick-concrete building structure, the traditional brick has a large proportion and consumes a lot of resources, which does not meet the green construction industry advocated by the state. Construction concept, wall panels, as an important part of them, have attracted everyone's attention. Wall panels are not only load-bearing components, but also room partitions. They are the most commonly used and economical structural forms in residential buildings. The use of building modules for construction has greatly increased the use of wall panels, so the production and processing of ...

[0002] In the existing life, with the continuous development of the construction industry, the requirements for the construction industry are also increasing. For the brick-concrete building structure, the traditional brick has a large proportion and consumes a lot of resources, which does not meet the green construction industry advocated by the state. Construction concept, wall panels, as an important part of them, have attracted everyone's attention. Wall panels are not only load-bearing components, but also room partitions. They are the most commonly used and economical structural forms in residential buildings. The use of building modules for construction has greatly increased the use of wall panels, so the production and processing of wall panels also put forward higher requirements

[0003] However, most of the existing wallboards are produced by directly passing the mixed wallboard raw materials into the inside of the mold when they are produced by extrusion molding. The wallboards produced in this way lack necessary toughness and are not conducive to use. At the same time, when the raw material is extruded into the mold, it is likely to cause uneven distribution of the raw material, which greatly reduces the quality of the produced wallboard.
