A technology for producing artificial travertine with gypsum

Abstract

A technology of using gypsum to produce artificial travertine comprises the following steps: (1) preparing a solution for artificial travertine; (2) fetching the solution for artificial travertine and gypsum powder; (3) pouring part of gypsum powder into the container of a granulating machine, stirring, at the same time, spraying the solution for artificial travertine, observing the agglomeration state of gypsum powder, and adding gypsum powder and spraying the solution under stirring until the particle size of agglomerated gypsum particles with different sizes reaches 0.5 to 10 mm; (4) spraying water on the surface of a workbench to form a water film; (5) evenly paving the gypsum particles on the surface of the workbench; (6) pressing the gypsum particles; (7) preparing slurry, pouring part of slurry on the pressed gypsum particles, and leveling the slurry; (8) paving an enhancing material (glass fiber); (9) pouring gypsum slurry, leveling the gypsum slurry, after initial set, carrying out scraping, trimming, and moulding, demoulding, carrying out maintenance, and drying in the air. The artificial travertine has holes with big inside and small outside and unique textures with different shapes and sizes and is similar with natural travertine.

Description

technical field [0001] The invention relates to a process for producing artificial travertine from gypsum. Background technique [0002] Natural gypsum is a kind of non-toxic, tasteless and pollution-free real green building material, which has the characteristics of light weight, heat insulation, sound absorption and fire prevention. At present, the routine production of gypsum products has several old and simple processes such as pre-casting, spraying, and leveling. They rely on molds to shape the surface patterns, and the patterns are repetitive. Create natural patterns like natural travertine with different sizes, disorderly distribution, large holes inside and small outside, and ever-changing shapes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of cavity that can produce large inner and outer small cavities with different shapes and sizes, aiming at the shortcomings that the pattern manufacturing ...
