The utility model relates to the technical field of dispersion discs, and discloses a threaded dispersion disc suitable for
color mixing of colorful paint and thick decorative paint, which comprises a rotating rod, a connector and a fixing ring are sequentially arranged at the lower part of the rotating rod from top to bottom, and a threaded head is fixedly mounted at one end, close to the connector, of the rotating rod. According to the threaded dispersion disc suitable for
color matching of the multicolor paint and the thick decorative line paint, dispersion discs in other shapes can be installed only by disassembling the connector and the fixing ring, the protruding block connector is aligned with the inserting connection groove to be inserted into the inserting connection groove, the sealing ring is inserted into the sealing groove, the preliminary positioning effect can be achieved, meanwhile, a
paint product enters from a large opening of the spiral head, and therefore the
paint product is not prone to falling off. When the
coating flows out of the small opening of the spiral head, the effects of increasing pressure and guiding flow are achieved, the
coating is driven to form a uniform dispersion vortex, the
coating can be better dispersed, the fixing ring, the bent rod and the spiral head which are integrally welded are adopted, the connecting strength of the spiral head and the fixing ring is enhanced, the disassembly and
assembly steps are reduced, and the practicability is improved.
