美國ASTM 新IRB9工業(yè)標(biāo)準(zhǔn)參比炭黑(美國原裝進(jìn)口)

　　北京冠遠(yuǎn)科技有限公司為中國總代理：美國ASTM新制定工業(yè)參比炭黑IRB9，常備現(xiàn)貨

　　ASTM系美國材料與試驗(yàn)協(xié)會(huì)的英文縮寫，其英文全稱為American Society for Testing and Materials。該技術(shù)協(xié)會(huì)成立于1898年

　　炭黑物理性能測(cè)試ASTM D412 ,D3182,D3192 ,D3191用工業(yè)參比炭黑IRB (industry reference black)，新標(biāo)樣IRB 9替代IRB8.

　　IRB 9與IRB8 相比，有多項(xiàng)不同，請(qǐng)見下表

　　標(biāo)準(zhǔn)參比炭黑 standard reference carbon black 一種具有典型物化性能、質(zhì)量均勻、性能穩(wěn)定的橡膠用炭黑。主要作為炭黑生產(chǎn)廠和橡膠制品廠驗(yàn)證試驗(yàn)重現(xiàn)性及再現(xiàn)性的標(biāo)準(zhǔn)物質(zhì)。目前炭黑工業(yè)和橡膠工業(yè)常用的標(biāo)準(zhǔn)參比炭黑是ASTM SRB (standard reference black),前后推出9個(gè)系列的SRB, 新系列為SRB 8，IRB (industry reference black)是用于炭黑橡膠性能的工業(yè)參比炭黑，已推出IRB 1---9#，目前新推出的是IRB9，國內(nèi)進(jìn)口中國總代理商主要是北京冠遠(yuǎn)科技有限公司，ITRB (industr tint reference black)是用于炭黑著色強(qiáng)度測(cè)試上用的參比炭黑，名稱為工業(yè)著色參比炭黑。
