What is the difference between organic glue and inorganic glue?

The "dawn of the inorganic era" has been revealed, but what is inorganic glue? Why replace organic glue with inorganic glue? What kind of impact will the use of inorganic glue have on table tennis? Not everyone is completely clear.

Organic glue is not necessarily toxic.

There is no equivalence between organic glue and toxic glue.

What is poisonous? What does it mean to be non-toxic? In the age of organic glues, this problem is difficult to be.

Both have a low boiling point opportunity as a solvent and rubber as a binder. However, the former solvent contains benzene, toluene, xylene and other substances, and the long-term inhalation of these substances may cause serious diseases, so it was banned by the International Table Tennis Federation in 1995. The most famous incident at that time was that after Jin Zezhu defeated Wang Tao at the Tianjin World Table Tennis Championships, he was found to have used toxic glue and his results were invalid.

Since 1995, most of the non-toxic glues used in bonding rackets have used long-chain alkanes or naphthenes as solvents, and a few contain additives with elastic effect. These substances are microtoxic or weakly toxic, and although they do not cause significant effects on the human body, they may still produce a reaction that is more than in the eyes of ordinary people when the concentration is labeled or the user is overacidic.

The occurrence of Japanese fans fainting while brushing glue became the fuse of the ITTF reform.

Inorganic glues use water as a solvent.

In the past, most of the glues used used were volatile organic solvents, which have low melting and boiling points, and volatilize quickly at room temperature and are easy to turn into gases. The non-volatile nature stipulated by the ITTF this time is based on water as a solvent, as long as the volatility is lower than that of water, it can be defined as "non-volatile", not necessarily water as a solvent.

In contrast to organic glue, inorganic glue uses inorganic matter (mostly water) as a solvent.

The economic driver behind the new rules.

Needless to say, the implementation of the new rules is a huge business opportunity for table tennis manufacturers.

Although on the surface, it only makes the glue change from "organic" to "inorganic", it can drive a series of changes in table tennis glue, bottom plate, rubber and sponge. Just in terms of glue, the ** of inorganic glue is much higher than that of organic glue.

Judging from the current market share, Japanese table tennis manufacturers will be the biggest beneficiaries of this reform.

The impact of inorganic glue.

In the organic era, the contestants used a large number of organic glue to "pour glue", and with the help of organic solvents to expand the rubber, the rubber produced a softer and fuller feel and better energy storage capacity, and finally gained greater power.

The solvent used in inorganic glue is inorganic, and theoretically cannot cause the rubber to "swell", so it will have an impact on the speed, power and rotation of the ball. Ma Lin said that if from the perspective of "faster, higher, stronger", this reform is undoubtedly the opposite, and former world champion Liu Guozheng said bluntly, "The viewing level of table tennis has regressed to the fifties and sixties of the last century." ”

However, Yu Bin, deputy director of the Table Tennis Center of the General Administration of Sport of China, said, "This reform of the ITTF has made table tennis greener, greener and healthier. The Chinese Table Tennis Association fully cooperated. ”

It doesn't have a big impact on the speed of the ball, it's not a curling ball.

Organic glue emits black smoke when burning, and inorganic glue does not emit black smoke when burning.

Organic Glue: Allows the sponge to expand quickly. Increases the speed after hitting the ball.

But this glue is volatile. Toxic gases are produced. Negative effects on the athlete's body.

So before the table tennis match. There will be a special place to stick the racket.

Inorganic glue: non-toxic. However, it will reduce the speed after the shot. According to the decision of the ITTF. After this Olympics. Always use inorganic glue. So that place dedicated to sticking rackets will also become history.

1. Inorganic glue is an additive that does not contain magnesium, phosphorus, aluminum, iron and other chemical components, good chemical activity, waterproof and moisture-proof, and less reduction of fixed carbon, and organic glue is a glue containing organic components. 2. Organosilica gel refers to a compound that contains Si-C bonds and at least one organic group is directly connected to silicon atoms, and compounds that connect organic groups with silicon atoms through oxygen, sulfur, nitrogen, etc. are often regarded as organosilicon compounds. <

Silicone water features.

This product is solvent-free, non-corrosive, easy to use and safe, does not pollute the environment, has excellent adhesion, excellent electrical insulation, moisture-proof, vibration-resistant, anti-aging, anti-arc and oil-resistant. It is widely used in the bonding and sealing of high-temperature equipment or high-temperature electronic products such as steam irons, rice cookers, electric irons, induction cookers, high-temperature air filters, high-temperature ovens, high-temperature pipes, etc.
