Description

technical field [0001] The invention belongs to the technical field of artificial granite manufacturing, and specifically relates to an intelligent manufacturing method of artificial granite based on the regulation and control of LBM-DEM aggregate gradation interface characteristics. Background technique [0002] Artificial granite is currently the most widely used and most used artificial stone. It uses natural marble chips and stone powder as the main raw material, uses unsaturated polyester resin as the cement, and uses high pressure and vibration to shape it. Curing at room temperature, cutting, grinding, polishing and other processes to make plates. At present, in the traditional artificial stone manufacturing industry in Guangxi and even in China, there are still common difficulties and pain points such as human operation and experience that have a significant impact on the performance and cost of artificial stone products.

Problems solved by technology

At present, in the field of traditional artificial stone manufacturing industry in Guangxi and even in China, there are still common difficulties and pain points such as factors such as human operation and experience that have a significant impact on the performance and cost of artificial stone products.

In the stage of sample preparation and trial production of artificial granite, the proportion of the aggregate system is mostly adjusted by experience, and it often takes multiple trials and deployments to obtain an ideal proportion formula. The trial production process is long and costly; in the face of large aggregates In the raw material products and the actual production process, the ratio of artificial stone raw materials has always followed the empirical formula, and the production technology is relatively backward, resulting in serious product homogeneity, and relying too much on the experience of production technicians.

While the production efficiency is low, there is still a lack of quantitative, scientific and intelligent key technology research that can guide the production of artificial granite

[0003] The inability to obtain the artificial stone aggregate formula affects the overall mechanical properties of artificial stone products from the inside, which has long puzzled the technicians in the artificial stone industry. At present, it is still urgent to explore the standardized method of obtaining the ideal artificial stone formula and break through the tradition. It is one of the effective ways to essentially reduce the production cost of artificial granite and improve production efficiency by improving the production process and improving the traditional process in the way of intelligent manufacturing
