The invention discloses a three-layer flow-extending snowflake-shaped glaze processing technology, which is characterized in that through cooperative work of matched processing equipment, a layered glazing and staged firing technology is combined to form runner, pinniform and snowflake-shaped three-layer glaze with clear layers, and through matching with a transparent glaze layer, the glossiness and the stability are improved. According to the technical scheme, the method is characterized in that the method is based on three-layer flow-extending snowflake-shaped glaze line machining related equipment, and the equipment comprises a ball mill, rolling forming equipment, a ventilation drying device, a rotary workbench, a feather-shaped smearing tool, kiln equipment and glaze dipping equipment; the aeration-drying device is used for adjusting the moisture content of a mud blank, the rotary workbench is used for fixing the disc body during glazing, the feather-shaped smearing tool is used for layered glazing, the kiln equipment is used for staged temperature control firing, and the glaze dipping equipment is used for applying transparent glaze; the method comprises the steps of pre-preparation, layered glazing, staged firing and transparent glaze layer forming.

The invention belongs to the technical field of moisture-conducting fabrics, and relates to a high-strength multi-dimensional moisture-conducting fabric and a preparation method thereof.The product is a three-dimensional orthogonal woven fabric with a four-layer plane structure and comprises warp, weft and binding warp, and the binding warp penetrates through the thickness direction of the fabric and connects the weft in each layer into a whole; the four layers of plane structures are formed by weft yarns arranged in parallel, and are sequentially a hydrophilic layer, a secondary hydrophilic layer, a secondary hydrophobic layer and a hydrophobic layer from top to bottom; during preparation, three warp yarns, two binding warp yarns and weft yarns in each layer are prepared, and hairiness-shaped fiber yarns forming the weft yarns in the secondary hydrophobic layer are hairiness-shaped fiber yarns with microfibers on the surfaces obtained after PP / PA6 composite fibers are soaked in an acetic acid solution and subjected to ultrasonic treatment. According to the method, the capillary effect of the plant, the asymmetric Janus effect on the two sides and the simulated plant root hair are used for achieving the one-way moisture guiding effect; the prepared product is good in moisture conduction effect and good in durability.

The invention belongs to the technical field of solid waste resource utilization, and particularly relates to a pinniform non-cemented gangue paste filling treatment system and a treatment method utilizing the pinniform non-cemented gangue paste filling treatment system, the pinniform non-cemented gangue paste filling treatment system comprises a pinniform underground filling device, a ground input device and a control display, and the control display is wirelessly connected with an upward input device; the ground input device comprises a storage bin, a discharging port of the storage bin is connected with a three-way rotary distribution valve through a feeding pipeline, three pipe openings of the three-way rotary distribution valve are a feeding port, a discharging port and an overflow port respectively, and the three pipe openings correspond to the feeding pipeline, the discharging pipeline and the overflow pipeline in a one-to-one mode and are fixed through pipe hoops. A pressure detection device is welded on the feeding pipeline; according to the application of the device, goaf areas of different waste old roadways can be flexibly filled at the same time, the efficiency is high on the premise that a coal face is not affected, the adopted pressure detection device is simple in structure, an inner core body of the pressure detection device directly makes contact with a medium, the reliability of a detection result is greatly improved, and errors are effectively reduced.
