Coating for Chinese zither faceplate

Abstract

The invention relates to the manufacture of a Chinese zither faceplate, in particular to a coating for a Chinese zither faceplate. The coating is prepared from, by weight, 20-32 parts of animal glue,3-8 parts of shellac, 12-18 parts of graphene powder, 1-6 parts of inorganic filler particle and 30-45 parts of 95% of ethanol solution; the thickness of a coating layer formed on the surface of the Chinese zither faceplate is 20-35 micrometers; the coating for the Chinese zither faceplate has the advantages that through the mutual cooperation among the animal glue, shellac, graphene powder and inorganic filler particle in the coating formula, not only can the surface rigidity and toughness of the Chinese zither faceplate be significantly improved, but also the Chinese zither faceplate can beprevented from being injured during use, and the rough surface formed by combing the facts that the coating layer is filled with the graphene powder and partial inorganic filler particles protrude thesurface of the coating layer ensures that the tone of the Chinese zither playing is accurate and the sound is natural and soft.

Description

technical field [0001] The invention relates to the production of guzheng panels, in particular to a coating for guzheng panels. Background technique [0002] Guzheng is an ancient national musical instrument, mainly composed of panels, wild goose columns, strings, front Yueshan, string nails, tuning box, Qin feet, Houyueshan, side panels, sound outlet, bottom plate and string holes. As far as the sounding principle of the zither is concerned, the conduction effect of the panel has a direct causal relationship with the vibration state of the zither body, which also determines the quality of the zither's acoustic quality. [0003] In the prior art, paulownia wood is generally used for the guzheng panel, which is soft and easy to be injured. In particular, if the guzheng panel is injured, the timbre will be affected, resulting in inaccurate timbre, thereby affecting the normal use of the guzheng. [0004] For beginners, when playing the upper and lower glissandos or the minor...

Problems solved by technology

[0003] In the prior art, paulownia wood is generally used for the guzheng panel, which is soft and easy to be injured. In particular, if the guzheng panel is injured, the timbre will be affected, resulting in inaccurate timbre, thus affecting the normal use of the guzheng

[0004] For beginners, when playing the upper and lower glissandos or the minor thirds, the nails of the left hand, especially the armor worn by the left hand, are very easy to touch the panel at the top, resulting in spotted wear on the panel. If it is not repaired, the outer tube of the guzheng will be unsightly, and the repair is not enough for ordinary sandpaper, so it brings distress to the guzheng users
