美國(guó)ASTM 新IRB9工業(yè)標(biāo)準(zhǔn)參比炭黑(美國(guó))
北京冠遠(yuǎn)科技有限公司為中國(guó)代理:美國(guó)ASTM新制定工業(yè)參比炭黑IRB9,常備現(xiàn)貨
ASTM系美國(guó)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
| ASTM 測(cè)試方法 | 測(cè)試項(xiàng)目 | 測(cè)試結(jié)果 |
| D3191, Method B | Carbon Black in SBR, Tensile Strength, Difference from IRB#7 | -0.33 MPa (-48 psi) |
| D3191, Method B | Carbon Black in SBR, Tensile Stress at 300% Elongation, Difference from IRB#7 | -0.63 MPa (-91 psi) |
| D3191, Method B | Carbon Black in SBR, Ultimate Elongation, Difference from IRB#7 | 5.5 % |
| D3191, Method C | Carbon Black in SBR, Tensile Strength, Difference from IRB#7 | -0.16 MPa (-23 psi) |
| D3191, Method C | Carbon Black in SBR, Tensile Stress at 300% Elongation, Difference from IRB#7 | -0.54 MPa (-78 psi) |
| D3191, Method C | Carbon Black in SBR, Ultimate Elongation, Difference from IRB#7 | 9.4 % |
| D3192, Method B | Carbon Black in NR, Tensile Strength, Difference from IRB#7 | -0.03 MPa (-4 psi) |
| D3192, Method B | Carbon Black in NR, Tensile Stress at 300% Elongation, Difference from IRB#7 | -0.09 MPa (-13 psi) |
| D3192, Method B | Carbon Black in NR, Ultimate Elongation, Difference from IRB#7 | 4.2 % |
| D3192, Method C | Carbon Black in NR, Tensile Strength, Difference from IRB#7 | -0.21 MPa (-30 psi) |
| D3192, Method C | Carbon Black in NR, Tensile Stress at 300% Elongation, Difference from IRB#7 | -0.36 MPa (-52 psi) |
| D3192, Method C | Carbon Black in NR, Ultimate Elongation, Difference from IRB#7 | -0.2 % |
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,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。
