Manufacturing process of high-performance inorganic artificial cave stone square stock
The invention discloses a manufacturing process for producing a high-performance inorganic artificial travertine square stock, which is characterized in that the inorganic artificial travertine square stock aggregate is prepared from the following components in parts by mass: 100 parts of Portland cement, 5.0 to 15 parts of auxiliary cementing material, 1.0 to 2.0 parts of polyvinyl alcohol (PVA) fiber and 1.0 to 1.5 parts of water-soluble polyvinyl alcohol powder (PVA powder), 1.0-2.0 parts of an efficient water reducing agent, 50-100 parts of inert mineral powder and 250-300 parts of inert mineral sand. And the aggregate is stirred by adopting a secondary stirring process, so that the PVA fibers are uniformly dispersed until the whole square aggregate is homogenized with other components. According to the second-stage stirring process, a high-speed dispersion stirrer and a high-speed shearing emulsifying machine are combined to form first-stage stirring of a second-stage stirring system, and PVA fibers, cement, an auxiliary cementing material, PVA powder, a water reducing agent and water are stirred and homogenized. And forming a second-stage stirring of the second-stage stirring system by the conventional forced stirring machine, and uniformly mixing and stirring the inert mineral sand powder and the PVA fiber-containing homogenized gel slurry obtained by the first-stage stirring, thereby finally obtaining the uniformly dispersed inorganic artificial cave stone aggregate containing PVA fibers. The comprehensive performance of the inorganic artificial travertine produced by the process exceeds the performance of inorganic artificial travertine and natural travertine produced by other processes at present.
