Random talk about clever powder
Qiaofen is an indispensable thing in billiards. There is no clever powder, no matter how expensive your club is and how advanced your leather head is, even if your club is made of anchor needles or century-old wood, the leather head made of dragon skin is the same. You can't play billiards without smart powder.
Don't underestimate Qiao Fen, it's not easy. Football originated in Europe or China (Cuju), and its developed places make us more worthy of respect. The ancestor of billiards is India. At that time, it was a game played on the grass, and later it was brought back to England by the British and became an indoor sport ... The original billiards game was very simple and rough. The so-called club is just a wooden stick, with no horns and no skin. The front end of the club is cut into an arc with a knife.
With the development of billiards, it is found that ... if the front end of the cue ball does not touch the center of the cue ball, it is difficult for the cue ball to move straight forward. If you don't believe it, you can hit the cue ball with bakelite leather head without applying smart powder ... In order to make the cue ball go straight without hitting the center, Jon Carr, an Englishman, invented the world's first smart powder at the beginning of the19th century. The technology of plugging the cue ball came into being at the historic moment ... The earliest clever powder was not a lump, but a powder, and its composition was lime powder, just like chalk written on the blackboard when we were at school. It is precisely because of Qiao Fen's invention that billiards have undergone earth-shaking changes. You may not have thought that Qiaofen was invented after the birth of 10, the world's first leather head. In other words, the history of Qiaofen is longer than that of leather head! ...
1890 or so, American WM cooperation. A. SPINKS and JACOB SCHAEFER, the top billiards players at that time, were born with the first solid joffin. That is, the smart powder we use now. The ingredients of this clever powder include lime powder, abrasive and other additives. Among them, abrasive is the most representative. Why do you say that? Don't worry, you look down slowly! Ha ha.
In 1897, WM. A.SPINKS applied for a patent and invented SPINKS CHEAK. Now it's probably gone. Anyway, it was 100 years ago. Now the production method of Joe powder is basically the same as before, but the amount of abrasive and lime powder in each brand is different, so why do you think this brand of Joe powder is easy to powder, and that brand is not very good?
The important raw materials of Qiaofen are calcium carbonate (lime) and abrasive, and the main function of abrasive is to generate friction on leather head, so that its pulverization effect is better. However, the friction of Qiao powder on the leather head is much lower than that of sandpaper, which is invisible to the naked eye.
