Abstract

The utility model provides a nanometer polishing tectorial membrane string, includes the heart yearn, twines the winding layer that the formation was on the heart yearn surface by winding wire spiral and covers the protective layer outside the winding line, the protective layer is formed by the stack of multilayer fluorocarbon paint tectorial membrane layer. The utility model discloses on traditional string basis, utilize the tectorial membrane technology to cover multilayer fluorocarbon paint tectorial membrane layer on the winding line of string, cover another layer after every layer tectorial membrane layer is dried, through multilayer tectorial membrane, whole tectorial membrane layer level is even and smooth, the tectorial membrane layer is inseparable, possess extremely strong oxidation resistance; because the thickness of every layer tectorial membrane layer is the nanometer, especially adopts the thinner fluorocarbon paint tectorial membrane layer of tectorial membrane thickness, so the whole thickness of last tectorial membrane layer is thinner, can improve anti attenuation ability by a wide margin, and the string pronunciation is bright, muddy, warm.

Description

Nano-polishing film-coated string

Technical Field

The utility model relates to a musical instrument accessory, especially a nanometer polishing tectorial membrane string.

Background

The surface of the string needs to be processed before the string leaves a factory, for example, the surface film coating process of the string improves the corrosion resistance and the rust resistance of the string, and further prolongs the service life of the string. The prior art of coating a film on the surface of a string has various forms, for example, the string with Chinese patent publication No. CN110517651A and the manufacturing method thereof comprise a string core and a string winding wound on the string core, wherein the string winding comprises a copper wire, a silver coating covered on the surface of the copper wire and a protective layer covered outside the silver coating, and the protective layer is formed by mixing paint and metal powder. The string film coating process is complex, the film coating thickness is large, and the attenuation of the tone quality of the string is large.

Disclosure of Invention

The utility model aims to solve the technical problem that a nanometer polishing tectorial membrane string is provided, and tectorial membrane layer level is even, and the tectorial membrane layer has extremely strong oxidation resistance, and the tectorial membrane layer thickness can be controlled at the nanometer, has both kept the tone quality that the original sound string should hold and has felt with the same direction as smooth outside, has improved the antitracking power again by a wide margin.

In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a nanometer polishing tectorial membrane string, includes the heart yearn, twines the winding layer that forms and covers the protective layer outside the winding line on the heart yearn surface by winding line spiral winding, the protective layer is formed by the stack of multilayer fluorocarbon paint tectorial membrane layer. The utility model discloses on traditional string basis, utilize the tectorial membrane technology to cover multilayer fluorocarbon paint tectorial membrane layer on the winding line of string, cover another layer after every layer tectorial membrane layer is dried, through multilayer tectorial membrane, whole tectorial membrane layer level is even and smooth, the tectorial membrane layer is inseparable, possess extremely strong oxidation resistance; because the thickness of every layer of tectorial membrane layer is the nanometer, especially adopts the fluorocarbon paint tectorial membrane layer that tectorial membrane thickness is thinner, so the whole thickness of tectorial membrane layer is thinner finally, can improve the anti-damping ability by a wide margin, and the string pronunciation is bright, perfectly thick, warm.

As an improvement, the thickness of each fluorocarbon paint coating layer is 50 to 150nm.

As an improvement, the protective layer is formed by overlapping 10 to 15 fluorocarbon paint coating layers.

As an improvement, the core wire is a steel core wire, and the winding wire is a copper wire, a silver-plated copper wire or an alloy wire.

As an improvement, a silver-plated polishing layer is arranged on the surface of the protective layer.

As an improvement, the fluorocarbon paint is metal fluorocarbon paint.

Compared with the prior art, the utility model the beneficial effect who brings is:

the utility model discloses on traditional string basis, utilize the tectorial membrane technology to cover multilayer fluorocarbon paint tectorial membrane layer on the winding line of string, cover another layer after every layer tectorial membrane layer is dried, through multilayer tectorial membrane, whole tectorial membrane layer level is even and smooth, the tectorial membrane layer is inseparable, possess extremely strong oxidation resistance; because the thickness of every layer tectorial membrane layer is the nanometer, especially adopts the thinner fluorocarbon paint tectorial membrane layer of tectorial membrane thickness, so the whole thickness of last tectorial membrane layer is thinner, can improve anti attenuation ability by a wide margin, and the string pronunciation is bright, muddy, warm.

Drawings

Fig. 1 is a cross-sectional view of the present invention.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, a nano-polished coated string comprises a core wire 1, a winding layer formed by spirally winding a winding wire 2 on the surface of the core wire, and a protective layer 3 covering the winding wire. The protective layer 3 is formed by overlapping a plurality of fluorocarbon paint coating layers, the thickness of each fluorocarbon paint coating layer is 50-150nm, in the embodiment, the protective layer is formed by overlapping 10-15 nanometer fluorocarbon paint coating layers, preferably 12 layers, the thickness is moderate, and the best timbre of the string can be exerted; in addition, the preferred type of fluorocarbon paint is a metallic fluorocarbon paint. The heart yearn 1 is the steel core wire, winding wire 2 is copper line, silvered copper line or alloy wire, and the string of copper line winding on the steel core wire is traditional guitar string, because the metal wire is direct exposed, easy oxidation can play fine antioxidation after winding wire parcel protective layer 3. During manufacturing, the concentration of the fluorocarbon paint is adjusted by a diluent, and each film is dried at low temperature until all the films are coated. The surface of the protective layer 3 is provided with a silver-plated polishing layer 4, so that the appearance of the string is more textured and fantastic in color.

The utility model discloses on traditional string basis, utilize the tectorial membrane technology to cover multilayer fluorocarbon paint tectorial membrane layer on the winding line of string, cover another layer after every layer tectorial membrane layer is dried, through multilayer tectorial membrane, whole tectorial membrane layer level is even and smooth, the tectorial membrane layer is inseparable, possess extremely strong oxidation resistance; because the thickness of every layer of tectorial membrane layer is the nanometer, especially adopts the fluorocarbon paint tectorial membrane layer that tectorial membrane thickness is thinner, so the whole thickness of tectorial membrane layer is thinner finally, can improve the anti-damping ability by a wide margin, and the string pronunciation is bright, perfectly thick, warm.
