1. Internal energy is a concept; Internal energy is the internal energy or internal molecular or atomic energy, may be set of internal energy mainly refers to the molecular energy, the internal molecule of the large deformation of the release of energy, if so, what set of rubber has internal energy, have deformation, have energy release, exaggerated even if the ball hits the iron plate has energy, but the deformation and energy release of the iron plate is not so obvious, the naked eye can not see.
2. How did this part of the internal energy come about? If a piece of internal energy rubber is placed there, he has always had energy released, I think people who have studied physics will know that it is not, its so-called internal energy is to rely on external stimulation or with the help of external force, just like the rubber sleeve, its internal energy is excited by the energy of the ball, in other words, the rubber is a link in the energy transfer process in table tennis, this link can not independently "release" energy, it can only "borrow" the energy to transmit energy, the difference is that the so-called internal energy transfer has an independent energy storage and release process, The ability of the internal energy rubber is the energy of the ball and the user itself, and from this point of view, the internal energy is no different from the ordinary rubber set. Energy is not generated in a vacuum, and the energy that is "generated" (in fact, transmitted) by internal energy depends on the energy of the ball and the user itself.
3. Say internal energy and glue; I was advised to use it if I thought about it, it is the glue that is liquid and will have a permeable effect on the sponge, and the micro-point of view says that the penetration of the glue into the sponge molecule will affect the deformation and elasticity of the sponge molecule in motion, and even the size of the sponge molecule, I think the expansion of the sponge sponge is this reason, whether it is inorganic or organic or toxic in the future, it will definitely have an impact on the performance of the glue. As for whether it is good to fill or not, it all depends on the user's preference!

The internal energy rubber is mainly for the elasticity of the rubber sleeve research, at the beginning to replace the effect of glue filling, increase the elasticity of the rubber sleeve, but the control and the service life of the rubber sleeve will be reduced, but under the impact of inorganic glue, the internal energy will be the mainstream. Now the internal energy is much easier to use than at the beginning, and the foreign ones are easier to use than the domestic ones.

Dear you, internal glue and inorganic glue are common types of glue, and the main differences between them are as follows:
1.The composition is different: the inner energy glue is an organic glue, the main component is polyurethane, while the inorganic glue is an inorganic glue, the main component is silicate.
2.The characteristics are different: the internal adhesive has strong adhesion and elasticity, and can withstand stretching and extrusion to a certain extent, while the inorganic adhesive has high heat resistance and corrosion resistance.
3.Different uses: internal adhesive is suitable for bonding various materials, such as metal, plastic, rubber, etc., while inorganic adhesive is suitable for bonding inorganic materials such as ceramics, glass, stone, etc.
4.The construction method is different: the internal adhesive generally needs to be mixed before construction, and then a special glue gun is used for construction, while the inorganic glue can be used directly.
In general, the internal energy glue and the inorganic glue are different in terms of composition, characteristics, use and construction method, etc., and it is necessary to choose the appropriate glue according to the specific use needs.

Look at the ability of several generations.
From the earliest F1, F1 can be used with organic glue, there is no obvious glue filling effect, and the rubber will not shrink.
A little later Joola top tango.
Organic glue can be used, and there is a glue potting effect, which belongs to the type that can be done without glue can be done with mu zhi, and the sponge expands after glue, and then retracts to the original level.
Andro's plasma has been used, and the reaction to organic glue is not obvious, but the bounce after pouring organic glue is not as good as when not brushing, it is best to stand for a period of time after brushing organic glue and wait for it to volatilize before pasting.
The platinum JO used now can be used with organic glue, and the sponge expands to a limited extent after brushing, and is roughly reduced by about 5mm after being removed from the bottom plate, and there is no obvious difference in performance.
Japanese rubber is used less, and only two pieces have been used.
Butterfly's G2-Soft has been used, and it is also an internal energy glue, although the rubber surface is different, but the sponge is similar to Tango, and it has a significant swelling effect after brushing organic glue.
Butterfly T05 is also limited expansion, but I feel that the elasticity has decreased in all aspects after expansion, and there is a shrinkage phenomenon, it is not recommended to brush organic glue (this piece seems to brush inorganic glue will also be slowly reduced due to the reduction of internal stress.) )
I've used these pieces myself.
There are also reviews from other friends on the forum, in general, organic glue can be used before the cake sponge, but it is best to stand and wait for the sponge to completely return to flatness before sticking.
As for the latest cake sponge, it is best to use inorganic glue to paste it completely, even if you use organic glue and other smoothing before pasting, it will accelerate its shrinkage speed and affect the performance.

Organic glue is toxic, but the racket sticky with organic glue is elastic and comfortable to pull the ball.
Organic glue is a spring-resistant glue that also has chemical components to help volatilize and help the sponge swell. However, due to its strong volatility and chemical composition, it is extremely damaging to human respirators! However, the advantage is that it is fast drying (2-3 minutes quick drying), which can enhance the elasticity of sea digging sponge.
Inorganic glue is in-contained.

If it is a recent one, it is almost impossible, because he has processed it himself, but it is not suitable to use the old organic glue.

It mainly refers to the internal energy sponge or loss, which is generally soft, and can retain the energy to the maximum extent and release it instantly when the violent squeezing is squeezed and rolled! The characteristics of this elastic deformation energy storage should be understood by those who have studied physics. In the past, athletes used to expand the sponge by brushing the glue to achieve the best performance, but now the use of inorganic glue is considered to use internal energy, which is forced by the form!
Inner energy sponge foreign ***.

In order to comply with the requirements of consumers to simplify the operation, a new type of rubber nesting called "built-in fast glue effect", that is, "internal energy type rubber nesting" has been developed, without the need for glue filling, it can also have the commonality of traditional rubber sleeve after "glue potting" - also because of this high tension, "internal energy type rubber nesting" further amplifies the consumable properties of rubber nesting. If the traditional rubber is repeatedly "glued", its service life will be seriously shortened, and the surface of the rubber of the "internal energy rubber covering" is inherently highly brittle, and it is easy to break after being bumped (some products are specially equipped with a protective film that is rare in Japanese and German rubber sets when they leave the factory), so consumers must have the corresponding economic conditions to be able to use it for a long time.

Cyanoacrylate, i.e., instant fast-following glue, ingredient cyanoacrylate glue, is a one-component, fast-curing adhesive synthesized through advanced production processes. Cyanoacrylates are versatile, easy to use, have very fast curing speeds, high bond strength, a wide range of bonding areas, and good adhesion to a variety of substrates such as metals, plastics, rubber, elastomers, paper, leather, fabrics, etc.
