palio3星無縫球,真係好似打爛波聲,個波打出來好似文具店果d玩具波一樣,睇來一d都唔好打
速度無,旋轉無,個波又飄,國際乒聯搞來搞去都唔知搞麥 ,麥野都無晒,不如打羽毛球
希望有改良版啦

小弟愚見: 雀得如果紅双喜出無縫波有機會修訂大過拍里奧...... 如果双喜出的無縫波很難說得定必會貴過拍里奧印上[紀念版]這三字的版本, 謀慣生活的眾人更會想[紀念版]來美化[未修訂] 較挺價

如果20元一個, 打多球練習時, 閒閒地要用2000-3000買波?
再講, 只係搞一次3小時球局, 我地多數會打爛/ 踏爛4-5個波,
如果真係20元一個, 每次咪無左100元
條數都好難計

http://mytabletennis.net/forum/f ... de-ban-of-celluloid

This message is posted on behalf of Mr. Adham Sharara.

Hi Lorenzo,

There is no upcoming world-wide ban of celluloid, this was a simplification of the current status and the status on the use of celluloid for many years past. Their is also no health issue with the finished product. The issue is in the manufacturing of the celluloid sheets that are used to make the ping pong balls. These sheets are produced from raw celluloid, which is a highly fibrous and flammable material. It is banned on commercial flights for many years now, this is nothing new. The use of the celluloid in producing products (ping pong balls, motion picture film, etc.) has become virtually extinct due to the very high health hazard to the workers using these materials. It is the same case for Asbestos. These are materials with very thin and minute fibres that are inhaled and stick to the lungs causing, as you can imagine, lung disease. In some western countries there is an outright ban on the use of asbestos or celluloid at the raw material level for many years now. There is no ban for the use of the finished product. This is quite hypocritical if you ask me "We do not want to hurt our people, but let others get hurt". The so-called "others" are waking up and realizing that such materials are harmful for their workers and have started to impose restrictions in production in form of a gradual decrease in the production for a steady reduction and eventual stoppage of production all together. Other governments have imposed very strict regulations for the factories that have celluloid production at the raw level. Some of these restrictions are very expensive, so manufacturers find it cheaper, and healthier, to change the material and use composites or plastics that are less hazardous or hopefully safe to use by the workers. The film industry as you probably know is going digital more and more every day.

For table tennis balls (ping pong) balls, the manufacturers have become almost extinct. There are basically 2 in China that produce good quality ping pong balls, 1 in Japan, and 1 in Korea. There was also one in Eastern Europe but it closed several years ago. I personally started to warn manufacturers more than 6 years ago, that the use of raw celluloid will be more and more regulated, as this was the trend in all other countries. This was taken seriously by Japan, and their solution was to buy balls made in China, same as the European companies have been doing for more than 20 years since the production of raw celluloid in their own countries was no longer viable. As you know, China was admitted to the WTO a couple of years ago and hence must abide by the WTO's standards and regulations. The celluloid production factories have been given a period of time to reduce their production, and the manufacturers that rely on the finished celluloid product are of course very concerned that they will no longer be able to produce their products in a few years time. This is when the two largest ping pong ball factories in the world (in China) woke up and started looking at other technologies to produce ping pong balls with other non-hazardous materials. The result is what we refer to today as the POLY balls.

Since a completely new technology was being invented for the new balls, I asked the manufacturers to seize this opportunity and produce better quality balls: seamless, round, even hardness, etc. This is hopefully what will happen. We will transform what could have been a crisis of having a shortage of ping pong balls, hence rendering them very expensive and probably extinct, to a positive result of better quality balls for all to enjoy. A by-product of this change is that POLY balls could be produced everywhere and not just in Chia. This may help make them more competitive and affect the price positively (cheaper) after a while.

I would like to stress that plastic balls have been in our regulations for more than 50 years, indeed Dunlop and Halex in England used to produce plastic balls, with an old technology, when they stopped producing raw celluloid in the UK at that time. So, as far as regulations are concerned there is no change, POLY balls are legal and always were. What would need a regulation change in a couple of years is the removal of the legality of using celluloid balls at ITTF events. However, we must give enough time to the manufacturers and resellers to deplete their stocks.

To answer your questions below, for (1), (2) and (3), perhaps I was misunderstood. The ban on celluloid production (also Asbestos) varies from country to country and started more than 30 years ago in some countries. The only countries left to produce raw celluloid used for the manufacturing of ping pong balls can be counted on the fingers of one hand. Already Japan is on a declining quota, and as of last year China is also on a declining quota. I am not sure about Korea. So, if we wait until these countries also stop the production of raw celluloid, then we would be in trouble. This is why we are pro-active and have pushed for a solution which remains within our rules and that was available to us all along. There are no other reasons for changing to POLY balls.

Regarding your question (4), yes, I am extremely concerned with the direction our sport has taken that has made the defensive player almost extinct. I really admire someone like Joo Se Hyuk who has persevered in the onslaught of attacking players. Players are asking for spinier and faster equipment all the time. This is always to the disadvantage of the defensive player. Faster blades, faster and thicker sponge, tackier rubber, etc., is all very bad for the defensive player. But that is the natural trend that the sport has taken. This is true in most sports.

I am not sure how the new ball will affect modern defensive players. Personally I thought that the increase from 38mm to 40 mm would help the defensive player, and it should. But most coaches and most defensive players were not able to figure out how to change and modify their techniques to take advantage of the new larger ball. They played the same way and found it more difficult to vary the spin and more difficult to attack from far. It took them a long time to adjust. This is why I admire Joo Se Hyuk, he is a classic defender (not how I imagined the evolution of a defender) and yet he remains in the top 10 in the World. Really amazing.

Regarding the new ball, the reports we have from the players that tried them is that it is more bouncy and less spiny. What does this mean for the defensive player? I don't know. Hopefully good news.

Please feel free to post this response to the Forum.

Lorenzo, I answered this e-mail exceptionally because of your genuine concern, however, you must understand that I receive more than 300 e-mails daily on my ITTF e-mail account and would find it difficult to engage in an exchange of e-mails. This is why I recommend that you post this response for others to see.

Thank you for understanding.

總之煩

作者: niceiceman 時間: 2013-5-8 10:26 標題: 有冇化學高手可解釋???

Celluloid is the combination of a relatively low nitrate level nitro cellulose and camphor.  The camphor is what you smell when you break open a ball.

Cellulose fibers are used to make nitrocellulose.  Typical fibers are cotton or wood pulp.  Yes, the same fibers used to make newspaper, facial tissue and your underwear (cotton). Cellulose fibers surround us.  Plants are about 30% cellulose fibers.  Lots of things are made from cellulose fibers and they aren't being banned.  In fact, some manufactures are promoting cellulose as a replacement for more dangerous or less environmentally friendly products such as asbestos and fiberglass.  You can get cellulose insulation for your home and concrete that is reinforced with cellulose fibers.

Nitrocellulose is made worldwide and there is no impending ban or any indication that its manufacture will be reduced in any significant degree.  Nitrocellulose is used for the making of inks, gunpowder and propellants, and nail polish and a few other things.

Here is but one company - in the U.K. that makes nitrocellulose.
http://www.nitrocellulose.com/index.html
Here's another company.
http://www.dow.com/dowwolff/en/c ... cellulose/index.htm

Nitrocellulose is typically shipped in containers where it is wetted with water or alcohol precisely because of its volatile nature.  Wet things don't tend to put fibers in the air - not that it would matter much anyway.  There are many kinds of protective gear that modern factory workers wear when there are airborne hazards anyway.  Many things are hazardous.  Modern man has, however, manages to successfully deal with many such things.  We drive in cars with many gallons of very flammable fuel and live in electrified houses.

I contacted a Japanese company that supplies celluloid for table tennis ball manufacturers.  They said that the notion that the hazards of celluloid being the same as for asbestos is imagined.

Celluloid production has diminished not because of hazards, but because for most applications, better (which might mean simply cheaper or might mean actually performs better) materials have been developed. That has been the case for some time.  I find it hard to believe that table tennis manufacturers know less about how to run their businesses than does Adham Sharara.  I doubt seriously that they needed him to tell them of any impending problem with the making of celluloid table tennis balls.  They aren't idiots.  They know they can't sell rubber, blades, tables and so forth if there are no balls to play with.  Nonetheless, apparently it took Adham's prodding get them to once again try seriously to come up with a different ball.

I seriously hope that the new ball has as many advantages as it does disadvantages.  Because frankly, if we are going to get railroaded into this change - as seems to be the case - I'd like for it not to be a disaster.

I find it hard to believe that celluloid manufacturing has been banned in any country.  The reason is simple.  Nitrocellulose is made all over the world, including in the U.K. and that's the dangerous/volatile component.  Combining it with camphor doesn't make it more dangerous, it makes it less so.  Celluloid manufacturing almost surely has become a niche activity because of the lack of demand.  Is there any wonder that it is being made primarily in China, Korea, and Japan - three countries where table tennis is quite popular?

The ITTF put out a pure fiction when they said that there was a worldwide ban on celluloid.  Even Adham must admit that was not true.  Though even then he's saying that was an oversimplification.  I'd like to point out that "fiction" does not equal "oversimplification."

One of their officials also put out the fiction that celluloid (or did he say nitro-cellulose?) production is 80% the same as nitro-glycerin.  That's another fiction.  Adham is associating cellulose fibers (I grew up next to cotton fields - egad!!) with asbestos.  Seems like a lot of hype being associated to celluloid and very little substance, facts and reference being offered to support any of it.  I, for one, am waiting for Adham to actually show some kind of reference to these bans, hazards and so forth.  I suspect the wait will be very long.

In the meantime, I'll leave it to the various forum members to decide for themselves if the things Adham Sharara and the ITTF is saying on this topic seem credible.  From what I've been able to find, it just doesn't add up.
