(1) Embeera ey'awamu ey'amakolero agakola emirimu gya kapiira .
As a kind of chemical material added in the process of rubber processing to improve the properties of rubber products, the development of rubber additives is closely related to the development of the rubber industry, especially the tire manufacturing industry.In 1839, the American Goodyear discovered that sulfur could be used as a vulcanizing agent to crosslink rubber, which made rubber have the use value. Since then, the world rubber additive industry was born.With the development of rubber industry, the Embeera y’ebirungo ebigattibwa mu kapiira mu mulimu gwa kapiira erongooseddwa, era tekinologiya alongooseddwa.
1,World Market Overview of Ebirungo Ebigattibwamu Ebipiira .
With the development of international rubber industry, especially the development of global tire industry, the world rubber additives industry ushered in a period of rapid development.In 2001, the world output of rubber additives was about 880,000 tons.In 2016, the world output of rubber additives reached 1.52 million tons, with an annual compound growth rate of 3.71%.In recent years, the global rubber industry has entered a period of stable development, and the supporting rubber additives industry has also entered a stage of stable development.In order to realize the optimal allocation of resources, over the past ten years, foreign rubber auxiliaries manufacturers have become more concentrated through mergers and acquisitions, forming four major rubber auxiliaries manufacturers, namely, American frax company, American cojua company, lanxine chemical company and Czech aigefu group company.China's rubber additives industry was founded in 1952, after more than 60 years of development, has formed a complete industrial system including all kinds of rubber additives, has become the world's rubber additives production and consumption power.With the rapid development of China's rubber industry, the output of rubber additives in China is also increasing rapidly.In 2001, the output of rubber auxiliaries in China was about 140,000 tons, accounting for 15.91% of the world output of rubber auxiliaries.In 2016, the output of rubber additives in China reached 1.21 million tons, with a significant increase compared with the annual output in 2001. The annual compound growth rate reached 15.46%.Mu 2016, China okukola ebigimusa bya kapiira yakola ebitundu nga 80% ku bigimusa bya kapiira mu nsi yonna, kifuuse ekigimusa kya kapiira ekisinga obunene mu nsi yonna.
Mu mwaka gwa 2016, obwetaavu bw’ensi yonna obw’okulwanyisa okukaddiwa, abatumbuzi n’abayambi ba kapiira abalala (okusinga abayambi ba kapiira ab’enjawulo) bwali ttani 520,400, ttani 408,800 ne ttani 521,000 ttani.Special rubber additives eziteekeddwa ku 36% ku 1000,000.
Ebirungo eby’enjawulo eby’ongera mu kapiira bikola kinene mu kulongoosa eby’obugagga n’omutindo gw’ebintu ebikolebwa mu makolero ga kapiira, okulongoosa obulungi bw’okufulumya ebintu ebikolebwa mu kapiira n’okutumbula okwekwata kw’ebintu ebitali bimu.Mu 2016, obwetaavu bw’ensi yonna obw’ebirungo eby’enjawulo eby’ongera ku mipiira byatuuka ku ttani emitwalo 5221, okweyongera kwa 2095} ttani 73% bwe kigeraageranyizibwa ku 2002, n’okukula kw’ekirungo 2000.
