How are cork boards made?

 

Cork board is a board made of grape bark. It has the characteristics of light weight, flexibility, sound insulation, waterproof, antibacterial, etc. It has been widely used in various fields, especially in the field of musical instrument manufacturing. missing materials. So, how are cork boards made? Let us find out together below.

 

The production process of cork board can be divided into the following steps:

  • Collect raw materials

The raw material for cork boards comes from the bark of grape vines. The vine is an evergreen plant that grows in areas with fertile soil, warm climates, plenty of sunlight and plenty of rain. The bark of the vine is the main raw material for the corkboard, so it needs to be harvested at the right time.

According to experience, the best time to collect grapes is before the vines go into dormancy, usually in summer. At this time, the resin content is the highest, and the bark is easier to peel off.

 

  • Peel off the bark



The harvested grape bark needs to be peeled off to remove the bark from the trunk. Stripping requires special knives and techniques to ensure that the bark and trunk are not damaged.

The stripped bark needs to be aired and dried for a period of time for subsequent processing.

 

  • Boiling treatment

The bark that has been sun-dried and dried needs to be boiled. The boiling process removes the resin and impurities in the bark, making the bark purer and softer.

During the boiling process, some chemicals need to be added to strengthen the toughness and elasticity of the cork board. The chemical added, usually sodium hydrocarbon ate, accelerates the softening of the bark and the breakdown of the cellulose, making the cork board softer and more pliable.

 

  • Cutting and compression

The boiled bark needs to be cut and compressed. Cutting is to divide the bark into pieces of a certain size for subsequent processing. Compression is the process of compressing the bark to make it tighter and harder.

For compression, the bark is compressed in special compressors, usually for hours or days. The compression process also needs to control the temperature and humidity to ensure the quality of the cork board.

 

  • Processing and coating treatment

Compressed cork boards need to be machined and coated to make the finished product. The processing requires the use of special tools and techniques to process the cork boards into different shapes and sizes to meet different needs.

The coating treatment is to strengthen the waterproof and antibacterial performance of the cork board. The coating material is usually a chemical called nano-silicon, which can form a protective film on the surface of the cork board to protect the board from moisture and bacteria.

 

The application of cork boards in the field of musical instrument manufacturing has many advantages. Here are some common advantages:

  1. Excellent sound insulation performance: Cork board has good sound insulation performance, which can effectively reduce noise and vibration, and make the sound quality of musical instruments purer.
  2. Excellent sound absorption performance: the cork board can absorb a lot of noise and sound waves, making the sound quality of the instrument clearer and brighter.
  3. Excellent elasticity and flexibility: The cork board has good elasticity and flexibility, which can adapt to various shapes and changes, making the playing of musical instruments freer and smoother.
  4. Excellent waterproof and antibacterial performance: cork board has good waterproof and antibacterial performance, which can effectively prevent the musical instrument from getting damp, bacteria breeding and other problems, and prolong the service life of the musical instrument.
  5. Excellent fireproof performance: Cork board has good fireproof performance, which can effectively protect the safety of musical instruments and make musical instruments more reliable.

 

To sum up, cork boards are more and more widely used in the field of musical instrument manufacturing, and can be used to manufacture piano frames, keys, piano beds and other components in various musical instruments such as woodwind instruments, stringed instruments, percussion instruments, and keyboard instruments. Cork board has excellent sound insulation, sound absorption, elasticity, flexibility, waterproof, antibacterial, fireproof and other characteristics, so it has been widely used in the manufacture of musical instruments.
