所列的产品的总碱值(TBN)在操作过程中用以检测和控制是有、润滑剂、生物柴油或混合生物柴油中的碱性成分。 总碱值(TBN) 在油和润滑剂中,被认为可能具有碱性特征的成分包括有机碱、无机碱、氨基化合物、弱酸盐(肥皂)、多价碱碱性盐和重金属盐。测试方法包括溶解氯苯/冰醋酸的无水混合物样本和用电位滴定法进行冰醋酸混合溶液中高氯酸的滴定。未使用和使用过的石油产品都包含作为添加剂的碱性成分。该测试有时间用作润滑剂降解的方法,但该测试的报废限度必须建立在个人基础上。所有都在合成碱油基质中
The products listed for Total Base Number (TBN) are used in procedures to test and control the basic constituents in petroleum, lubricants, biodiesel or blends of biodiesel. Total Base Number (TBN) The constituents of oils and lubricants that may be considered to have basic characteristics include organic bases, inorganic bases, amino compounds, salts of weak acids (soaps), basic salts of polyacidic bases and salts of heavy metals. The test methodology involves dissolving the sample in an anhydrous mixture of chlorobenzene/glacial acetic acid and titrating potentiometrically with a solution of perchloric acid in glacial acetic acid. Both new and used petroleum products can contain basic constituents that are present as additives. The test is sometimes used as a measure of lubricant degradation but any condemning limits based on the test must be established on an individual basis.All in a Synthetic Base Oil Matrix
