The present invention discloses an artificial stone slab, wherein the raw materials are mixed, pressed, and solidified, and the raw material comprises a main material and an auxiliary material. The main material, according to the total weight ratio of raw materials, comprises from about 20% to about 85% of particles containing hydroxide or metal oxide, from about 0% to about 50% of natural quartz, and from about 5% to about 25% of resin. The auxiliary material comprises a coupling agent and a curing agent, wherein the weight ratio of the coupling agent to the resin is from about 0.6:100 to about 2:100, and the weight ratio of the curing agent to the resin is from about 0.8:100 to about 1.2:100. The present invention also provides methods for manufacturing the aforesaid artificial stone slab. The present invention replaces natural quartz particles with particles containing hydroxide or metal oxide and ensures that the performance of the slab is up to standard, that the quality is more stable and easier to control, the decorative results are better, and finally, the mining of natural quartz is reduced by 10 times, achieving the objectives of greater environmental protection and lower costs. The resulting slab provides stable performance with good decorative results and thus saves resources and is conducive to environmental protection.

This document describes systems and processes for forming improved synthetic molded slabs suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

A method for realising a ceramic slab, comprising the following steps: arranging on a first deposition plane (50) a decorated layer (L2) provided with a decoration (200), gradually depositing the decorated soft layer (L2) from a head (H) to a tail (T); gradually transferring the soft layer (L2) by deposition from the first deposition plane (50) to a second deposition plane (83), placed at a lower height than the first deposition plane (50), starting from the tail (T) of the second soft layer (L2), gradually realising a second layer (L3) on the second deposition plane (83).

Disclosed is a distribution device and a manufacturing method for a full-body textured porcelain stoneware slab and relates to the field of construction ceramic tile production. The distribution device includes a feeding assembly, a powder-preforming box, and a belt conveying assembly, where the powder-preforming box is arranged at an included angle α with a conveying plane of the belt conveying assembly, and 61°≤α≤90°, and an intersecting line of a lower end of the powder-preforming box and the conveying plane of the belt conveying assembly is at an included angle β with a center line of the conveying plane of the belt conveying assembly, and 45° ≤β≤90°. A process using the distribution device can produce a full-body textured porcelain stoneware slab of a natural flowing effect, and can form a straight or diagonal textured pattern effect as needed.

The invention relates to a method and a plant for the continuous production of engineered stone slabs. In the method, raw materials comprising at least one mineral filler and one organic binder are mixed, applied to a lower belt of a dual-belt press, or a conveying means mounted upstream of the lower belt, and subsequently continuously pressed, and the binder is cured. A continuously-obtained material strand is separated into individual engineered stone slabs. It is provided that the mixing operation of the raw materials is carried out at staggered times in a batch mixing operation by means of at least two separate mixing devices. The mixed raw materials from the mixing devices are transferred into one, or multiple, spreading device(s) at staggered times and are applied continuously and without interruption to the lower belt, or the conveying means mounted upstream of the lower belt, by means of the spreading device(s).
