炭黑(碳黑)N220 原产地 山西、上海 含量 95(%) 产品等级 工业级 本公司热解炭黑由沥青生产而成的平均粒径为40~50nm,聚集体与GPF炭黑相似,由于灰份为14±2%,并以二氧化硅、钴盐类及锌类为主,所以表现在化学和物理性能上较为独特,有较高的交联度和扩散性。与N550有相似的加应(拉伸强度),与N772相似的模数值(定伸应力),与N330相似的撕裂强度。因此热解炭黑在橡胶配方中,不仅具有较好的填充补强作用,而且能改善混炼胶的炭黑分散均匀性,提高橡胶半制品的加工性能,所以热解炭黑已应用于尼龙斜交轮胎中的内层帘布胶、外层帘布胶、胎侧胶、内衬层胶及内胎胶等配方中,在不调整上述原配方中其他配合剂的条件下,以20―30质量份取代N550∕772等常规炭黑,不影响成品轮胎质量。除此以外,热解炭黑还广泛应用于电缆、胶带、密封件、胶辊等橡胶制品中。 型 号 N220 吸碘值: 28.1 加热减量%≤ 1.3-1.5 DPB吸收值 61 着色强度% 82-90 45筛余物%≤ 0.100 杂物 无 300%定伸应力 -11.4 拉伸强度: -13 扯断伸长率: 24 N220 carbon black (carbon black) Country of origin Shanxi, Shanghai content 95 (%) Product level Industrial grade Pyrolytic carbon black produced by asphalt and the company into an average particle size of 40 ~ 50 nm, aggregation and GPF carbon black are similar, because ash is 14 + / - 2%, and silicon oxide, cobalt salts and zinc is given priority to, so performance is unique in the chemical and physical properties, a higher degree of crosslinking and diffusivity. Similar to N550 have the strengthening effect of (tensile strength), similar to N772 modulus value (and stress), similar to N330 tear strength. Therefore pyrolysis carbon black in rubber formula, not only has good filling reinforcing effect, and can improve the uniformity of the carbon black dispersion of mixing rubber, improve the processing performance of rubber tire, so nylon bias tyre pyrolysis carbon black has been applied in the inner fabric glue, outer layer cord fabric rubber, tire rubber, rubber and rubber inner lining layer, such as formula, without a change in the original formula of other conditions, chelating agent with 20-30 quality replacement 772 conventional carbon black N550 /, does not affect the quality of tire. In addition, pyrolysis carbon black is widely used in cable, tape, seals, rubber roller and other rubber products. N220 type, Iodine sorption value: 28.1 Heating loss % 1.3 1.5 or less DPB absorption value 61 Tinting strength % 82-90 45 screenings % 0.100 or less Impurities without 300% stretch stress - 11.4 Tensile strength: - 13 Elongation at failure: 24 执行标准 : 国标 ; CAS : 优级 ; 应用推荐 : 涂料 ; : 山西 ; 种类/用途 : 色素碳黑 ; 型号 : N220 ;
