What should I do if the musical instrument cracks because of the dry weather?

Solve the problem of musical instrument cracking caused by dry weather;

1, the gap of the piano rod is filled with good 502 glue, and then it is lightly polished with 400 # water mill sandpaper after drying, then it is repeatedly polished with coarse cotton cloth, dried with a hair dryer after being coated with beeswax, and then it is repeatedly polished with coarse cotton cloth.

2. This method can also be used for piano barrels. If the joint is large, it is necessary to wrap the piano barrel tightly with cotton rope before gluing.

3. Stay away from the heating. In the dry season, it is necessary to add a small box filled with sponge water to the piano box. It is best for the sponge to absorb enough water without flowing out, and then drill a few small holes in the lid of the box. Cover the piano cover when not in use, to avoid water bouncing too fast, and pay attention to daily maintenance, which will last a long time.

preventive maintenance

Avoid high temperature drying. If the room is dry, put a small fish tank or a glass of water to increase the humidity. After playing, stand upright for a while and let the saliva in the pipe be automatically discharged and stored (because the flute absorbs too much water, it is easy to get wet, and dry air outside will cause cracking); Try not to play outdoors when the weather is too cold; Don't take it directly from outdoor to indoor or indoor to outdoor, so as to avoid cracking caused by hot and cold alternating too fast.

Before blowing in winter, if the environment is cold, you can cover the flute for a while and wait until it is a little warmer before blowing. Don't put it aside quickly after blowing, but hold it in your hand for a while, and then put it away when the flute is a little cold. If all the above measures are done, we can regularly apply glycerin vanishing cream and other pastes with anti-cracking effect on the surface and inside of bamboo (usually once every two months), and we can wrap cloth strips with small tubes for daubing inside.
