How to prevent moisture and how to preserve the pipa

For the care of pipa instruments, the following points should be noted:

1. Moisture-proof The joint of the double hand, headstock and body of the pipa is usually bonded with swim bladder glue (commonly known as fish maw), and this kind of glue is afraid of moisture, and if it is damp, it will open the glue.

Many players are accustomed to using steel wire strings, which will leave rust spots on the strings when wet, and the tone will be greatly affected.

2. After practicing, put the instrument into the piano case or case, and place it in a dry place that is not easy to be collided.

3. Develop the habit of wiping the strings after practicing.

During the sweat-prone season, sweat stains on the strings, especially the steel strings, can affect the timbre and pitch of the instrument.

When not in use, use a piano case or piano case to pack up the pipa and place it to prevent moisture.

After the pipa is damp, the joint is easy to crack, the timbre is stuffy, and the tone is inaccurate.

When not in use, use a piano case or piano case to pack up the pipa and place it to prevent moisture.

Don't put the case on the ground, put it as high as possible, put moisture-proof agent in the case, and pay special attention to spring

Just eat the biscuits, there is a desiccant in them, and they can be moisture-proof when placed in the piano case.

It is best not to put it directly on the ground. Instead, it should be placed on a shelf, and the lowest setting of the hair dryer should be used at intervals (be sure to use the lowest setting!). Can't get too close! )

The piano will grow green hair when it is wet, my last time was, faint! There may also be tiny, tiny bugs!

Anyway, be kind to your piano!

How to deal with moldy pipa:Dry the pipa thoroughly (but never bake or expose to the sun), then use a high-grade eraser to wipe away mold spots and stains.

How to prevent mold on the lupa:The mold of the pipa may be too wet, it may be that the material itself is not dry enough, but also because of the humid climate. Especially in the south, when there is a rainy spring, it is more likely to get mold.

The recommended method is to wipe off the mold spots with a soft paper towel before each play, and after playing, also wipe it again to avoid sweat stains from being left on it. You can wash the piano bag (the piano case can't help it).

Either it wasn't bottled properly, or the temperature was too high, or the packaging wasn't properly sealed.

You can place mold packs in the box.

Pipa maintenance tips

1. Don't be injured: because the pipa panel is made of loose paulownia wood, it is not lacquered to protect it, so it is necessary to take care of it in use, keep the panel clean, so as not to affect the appearance quality, try not to collide with the panel, in order to reduce the wear and tear of the panel, prolong the service life, after the performance, when the pipa is placed on the table, it is advisable to put the pipa flat on the table, in case you need to lean upright against the wall, you can only lean against the corner of the wall, so that the four pillars of the pipa are against the walls on both sidesIt can avoid external injuries such as falling damage to the head of the pipa or falling damage to the bottom of the pipa.

2. Pay attention to moisture-proof: the pipa is mainly composed of dozens of wood parts, all of which are bonded with glue, such as: the headstock itself, between the headstock and the body, the pipa panel itself, between the panel and the turtle plate, between the compound hand and the panel, no matter what glue is used for gluing, there is a problem of fear of moisture, and the glue parts are easy to crack after moisture.

After using the pipa, it should not be placed in a humid place, let alone by rain, it will absorb a lot of water after being wet, which can cause changes in sound, reduce the volume, and cannot lean on a heat source, such as heating.

3. The compound hand of the pipa is made of high-grade bamboo through special processing, which plays a great role in the timbre quality of the pipa, because the compound hand is suspended, the thickness is not large, and the tension of the four strings is very easy to break.

4. False nails should be selected: after the use of metal strings in modern times, the right finger needs to wear a false nail to play, in the past, thin copper sheets, thin aluminum sheets, thin horn pieces, thin ivory sheets, etc. to make long round false nails, this kind of false nails or with metal noise, easy to damage the string body or too thick and dull pronunciation, not ideal. False nails should have three requirements: appropriate thickness, tough and wear-resistant texture, and smooth surface.

The tip of the outer tip of the thumb can be made more prominent; Make the tip of the index finger** into a semicircular protrusion; The middle, name, and little finger are generally used to play the string with the tip of the nail, and the real nail of the finger is completely similar in roundness, curvature, and roundness, and the length should be slightly longer than the real nail.

I remember someone once said: The pipa is like a child, the luthier brought it into this world, and I took it in my arms, so I must take care of it. Yes, only if you love it, Fledo will bring you a more beautiful ** to repay you, so everyone who loves the pipa should take care of it like their own children.

1. The pipa is mainly composed of dozens of wood parts, all of which are bonded with glue, so the storage can neither be too humid nor too dry, do not put it in a damp and unventilated room in the south, and do not put it near the radiator in the northern winter, the pipa panel is very soft, when playing, the right fingernail is easy to wear the panel, if you practice, you can consider pasting a small piece of transparent plastic to protect the panel, which does not affect the timbre, after using the piano, wipe the pipa strings with a soft cloth with oil, and when you walk around with the pipa in your hand, The pipa should be held vertically with both hands to avoid collision, and it should be handled with care, and a more stable platform should be selected for temporary placement, or placed in the corner of the wall to prevent it from falling, and it should be placed in the pipa bag when not in use.

2. The pipa panel is made of loose paulownia wood, and it is not lacquered to protect it after it is made, so it is necessary to take care of it in use, keep the panel clean, so as not to affect the appearance quality, when playing, try not to collide with the panel fingers, so as to reduce the wear and tear of the panel, and prolong the service life.

3. At present, the commonly used pipa strings are the pipa strings of Beijing and the pipa strings of Shanghai, now people generally use the strings of Beijing for one string, the second, third and fourth strings are used for Shanghai, the pipa strings are made of nylon wire and multiple strands of thin steel wire, when winding, the shaft should not be too strong, the mountain pass should be smooth, reduce the resistance, after playing the piano, wipe the strings with a soft cloth soaked in a small amount of lubricating oil, remove sweat stains, and prevent rust.

4. The double hand of the pipa is made of high-grade bamboo through special processing. It plays a great role in the timbre quality of the pipa, because the compound hand is suspended, the thickness is not large, plus the tension of the four strings, it is very easy to break, so you should be careful when using, do not bump, when fixing the strings, the strength of the hinge should not be too large, and the timpani should be in place; When transporting, you can use a softer wooden block to make an oblique triangle shape, and gently stuff it into the upper and lower parts of the compound hand to play a certain supporting role.

How to maintain the pipa.

There are several aspects that should be paid attention to when maintaining the pipa: after the pipa is used, develop the habit of putting it in the piano bag or piano case immediately, and put the piano bag or piano case in a dry and proper place. For example, after the performance, when temporarily placing the pipa on the table, it is advisable to place the pipa flat on the table, and it is not appropriate to place the pipa upright against the wall.

If you need to lean upright against the wall, you should only lean against the corner of the wall so that the four pillars of the pipa are against the walls on both sides, so as to avoid the most common external injuries such as falling on the head of the lute or falling on the bottom of the lute.

At present, when sticking the panel and head, water glue such as yellow croaker glue is generally used, this kind of glue is most afraid of moisture, and degumming will occur when it is damp, and after degumming, the volume will be weakened and the timbre will be more damaged. Therefore, it should not be placed in a damp place, nor can it be wet by rain, and another reason why the pipa is not damp is that when the panel is wet by water stains, a large amount of water is absorbed in the sycamore board, and the volume will be weakened.

Therefore, even after the use of chemical glue that is not afraid of moisture in the paste, etc., the moisture-proof of the pipa should still be regarded as an aspect that needs to be paid attention to. It should also be avoided from direct sunlight; When not in use for a long time, the strings should be relaxed to avoid degumming of bergamot; After long-term use, some of the bamboo products of the pipa will wear out more, which will cause the product to be beaten, so you can go to a professional musical instrument sales store to replace the product.

Loquat is a very "delicate" fruit, and if it is left at room temperature for a few days, it may rot and deteriorate. This can be solved in the following ways:

1. To control the "breathing" of the fruit and maintain its original flavor, you can cool the fruit down. When the temperature is cooled, the breathing intensity of the fruit decreases, delaying the ripening process of the fruit, while also "absorbing" the heat emitted by the fruit when it "breathes". 2. It is impossible to completely keep fresh just by cooling down, and the packaging of fruits is also very important.

There is a microporous film with very small air permeability on it, which is a good material for fruit packaging! "The air holes are small and retain moisture in the fruit and reduce water evaporation. It is understood that the shelf life of fruits stored and packaged through this "perishable fruit tree preservation packaging technology" can be greatly extended.

For example, at room temperature, the shelf life of loquat fruit is about 8 days, but it can be extended to 45 days with this technology.

Loquat, the ancient name of Chinese Lu Tang, also known as golden pill, Lu Branch, is a genus of the apple subfamily in the Rosaceae family, which is a small evergreen tree. The canopy is rounded, the trunk is quite short, and the tree is generally 3 to 4 meters high. The leaves are thick, dark green, with villi on the back and serrated edges.

Loquat is native to southeastern China and is named after the shape of the fruit that resembles a pipa instrument.
