China's Carbon Fiber
Is féidir an taighde ar thionscal snáithíní carbóin sa tSín a rianú siar go dtí na 1960idí.
However, until 2000, the industrialization of carbon fiber has not been realized, and due to the long-term development of carbon fiber preparation technology in China, various research units gradually began to have insufficient confidence. RD personnel from all walks of life have avoided the word "carbon fiber". At this time, it is the most difficult trough period for the localization and research and development of carbon fiber materials.
I gcomhthéacs an chúlra seo, ghlac an tUasal Shi Changxu, eolaí straitéiseach agus acadúil d'Acadamh Eolaíochtaí na Síne agus Acadamh Eolaíochtaí na Síne, an lámh in uachtar ar thionsclaíocht snáithín carbóin a phlé i 2000.
At the beginning of 2001, the teacher sent a "request report on accelerating the development of high-performance carbon fiber" to the Party Central Committee. In October 2001, the Ministry of Science and Technology of the People's Republic of China decided to set up a special project on carbon fiber key technologies, code-named 304 special project.
Ó shin i leith, tá an tSín tar éis dul isteach go hoifigiúil sa lána tapa taighde agus forbairt neamhspleách ar shnáithín carbóin ...
Conas a éiríonn snáithín carbóin coitianta thar lear?
Ag deireadh an 19ú haois, chum na Breataine Joseph Swan agus Meiriceánach Thomas Edison filiméad carbóin sa tóir ar filiméid bolgán solais feabhsaithe. Cé gur cuireadh filiméid tungstain níos saoire in ionad an fhiliméad charbóin seo ag an am, meastar anois gurb é an t-ábhar snáithíneach carbóinithe seo an táirge tosaigh is luaithe de shnáithín carbóin.

Sa fhorbairt stairiúil ina dhiaidh sin, measadh go raibh filament carbóin i gcónaí mar mhainneachtain optamaithe filament, agus ní bhfuair sé aird i dtionscal agus i dtáirgeadh.
Until that magical organization, NASA, appeared on the stage of history, this new type of aerospace material with high temperature resistance, corrosion resistance, high strength and low density was reconnected to modern civilization and was named "carbon fiber".
Just as diapers, air-cushioned shoes, and dehydrated vegetables have all moved from NASA to the civilian field, carbon fiber, as the "new love" found by NASA in the material industry, is naturally valued by various companies to see if it can be the first. A person who eats crabs is the first to seize the market and make a fortune.
As a result, the United Carbon Compound Company UCC entered the carbon fiber development industry, and in 1959 developed the world's first listed viscose-based carbon fiber material Thornel-25.
Ag an am sin, le linn an Chogaidh Fhuair idir an tAontas Sóivéadach agus na Stáit Aontaithe, thosaigh rásaí arm éagsúla. Má tá eitleán agat, rachaidh mé go dtí na cruinne, agus má théann tú chuig na cruinne, rachaidh mé go dtí an ghealach. Mar ábhar le feidhmíocht den scoth i réimsí aeraspáis agus míleata, baineadh úsáid as snáithín carbóin go forleathan freisin.
An chéad fhear ar an ngealach: Armstrong
Ós rud é go bhfuil gá ag na Stáit Aontaithe, ansin tá an tSeapáin déanta.
At that time, Japan, as the largest "trophy" of the United States in World War II, also began active research on carbon fiber.
In fact, UCC's Thornel-25 is actually not perfect. The technological name of carbon fiber was synonymous with banknotes in the 1950s. According to the price of gold at that time, carbon fiber of the same quality was more expensive than gold. The high cost of proper black gold became the biggest pain point of carbon fiber at that time.
I 1961, d'éirigh le Akio Shinto ó Saotharlann Tionscail Osaka an teicneolaíocht chun snáithíní carbóin polyacrylonitrile (PAN) a ullmhú.
Shinto Akio
Roimhe seo, bhí an táirgeacht charbónú de shnáithíní bunaithe ar vioscós de chuid NASA réasúnta íseal, gan ach 20 faoin gcéad . Is é sin, tar éis 100 kg de snáithín atá bunaithe ar vioscós a charbónú, ní féidir ach 20 kg de shnáithín carbóin a fháil.
De réir fhoirmle mhóilíneach vioscós, tá thart ar 44 faoin gcéad ar chomhréir na n-adamh carbóin, ach sa phróiseas carbóinithe, imoibríonn leath na n-adamh carbóin le ocsaigin, hidrigin agus nítrigin. Mar thoradh air seo freisin tá feidhmíocht níos ísle de shnáithín carbóin bunaithe ar vioscós, rud nach bhfuil sásúil.
D'úsáid Akio Jindo go bhfuil tréithe cobhsaíochta teirmeach ag PAN tar éis réamh-ocsaídiúcháin, is é sin le rá, le linn an phróisis charbóinithe, níl gníomhaíocht cheimiceach na n-adamh carbóin de shnáithíní PAN ard, agus is féidir leis na hadaimh charbóin a bheith go maith. chothabháil.
Facts have proved that Kondo Akio's judgment is correct. The carbonization yield of the process route he developed is between 50-60 percent , and the performance is far superior to viscose-based fibers. The conversion rate has risen, and the price has naturally fallen. Since then, PAN has quickly replaced viscose-based carbon fibers. Now the share of viscose-based carbon fibers is less than 10 percent , while PAN-based carbon fibers account for more than 80 percent of the share.
Leis an gcéad{0}}teicneolaíocht ullmhúcháin láimhe de réamhtheachtaí polyacrylonitrile, d'éirigh le Toray a bheith ar thús cadhnaíochta maidir le hullmhú snáithíní carbóin.
Subsequently, in 1971, Japan's Toray Company (Toray, English name 'Toray Industries, Inc) cooperated with United Carbon Compounds of the United States to produce T300 carbon fiber, and achieved mass production of 1 ton/month at that time.
Subsequently, Toray Company continued to upgrade the quality of carbon fiber along the T300, T800, T1000, and pioneered the addition of carbon fiber materials to sporting goods such as rackets, fishing rods, golf clubs, etc., which became a sought-after product in the sporting goods industry. Japan's Toray also rose to fame, becoming the world's largest manufacturer of carbon fiber materials.
