1 Scope

GB/T 22836-2008 is the Chinese national standard on pulp - determination of fiber fibrillation, in the field of paper technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 December 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 September 2009.

This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the method for measuring the rate of pulp fibers broom. This standard applies to the determination of the degree of fiber broom or paper pulp.

3 Terms and Definitions

The following terms and definitions apply to this standard.

3.1 In the cell walls, cellulose chains gathered together to form tiny wires.

3.2 After beating action of physical or chemical fibers to produce fluff wall, tearing, in silk and so on.

5 Reagents and materials

5.1 Unless otherwise stated, the analysis uses only recognized as analytical grade reagents and distilled or deionized water or equivalent purity.

5.2 zinc chloride iodine dye (Herzberg stain) formulation

5.2.1 saturated solution of zinc chloride Zinc chloride (ZnCl2) was added to the warm water of about 100mL, until the remaining dissolved solute is no longer allowed to cool to room temperature, and observed there Zinc chloride crystallization. The solution was stored in a brown reagent bottle aside.

5.2.2 iodine solution Mixing potassium iodide (KI) 2.1g and iodine (I2) 0.1g, pipette 5mL of water was added dropwise, stirred to mix with addition of water.

Note. Iodine was dissolved in a small amount of water is important, and potassium iodide was added to dissolve the iodine. If there have not been dissolved and residual iodine may be due to added water Too fast, this solution should be discarded.
