ANSI/TAPPI T240 om-2012 浆料悬浮液的一致性(浓度)

This method describes the measurement of pulp consistency (concentration) of aqueous fiber suspensions. The method applies to most pulps sampled from different process points in a pulp or paper mill. The method is applicable to pulps with up to 25% consistency.

ASTM D817-12 乙酸丙酸纤维素和乙酸丁酸纤维素测试的标准试验方法

7.1 Ash content gives an estimate of the inorganic content of cellulose ester samples. The presence of high levels of inorganic content (ash) can be detrimental to the melt stability and optical clarity of a cellulose ester in melt processing or act as a potential source of insolubles when the ester is used in solution. 1.1 These test methods cover procedures for the testing of cellulose acetate propionates and acetate butyrates. These esters may vary widely in composition and properties, so certain of the procedures can be used only in the ranges of composition where they are suitable. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 The test procedures appear in the following sections: Sections Acetyl Propionyl or Butyryl Contents 28-37 Acetyl Content, Apparent 18-27 Acidity, Free 12-

The following interrelationships will be found particularly useful in predicting the effect upon opacity when a change occurs in either the basis weight or the reflectivity of a sheet of paper. These interrelationships can also be used to evaluate relative contributions of different pulps, fillers and pigments to optical properties.
