Foreword
GB/T 12006 "plastic polyamide" is currently divided into the following two parts.
--- Part 1. Determination of viscosity number;
--- Part 2. Determination of moisture.
This section GB/T Part 112 006, equivalent using ISO 307.2007 "plastic polyamide viscosity number determination" (in English),
Exactly the same technical content. For ease of use, this section made the following editorial changes.
--- To the "international standards" be replaced by "this section";
--- Remove the ISO 307.2007 Foreword Introduction;
--- Increasing the preface of this section;
--- Use of decimal symbol instead of the international standard decimal symbol ",". ",";
--- For ISO 307.2007 international standard referenced, not tantamount to the adoption of the standards of China, are directly referenced in the standard.
This Part replaces GB/T 12006.1-1989 "polyamide viscosity number determination method", compared with the GB/T 12006.1-1989, the main technical
Art content changes as follows.
--- Change the standard name;
--- "Normative references" a different chapter;
--- Increased Chapters 9 and 13 chapters;
--- Increased three solvents (see 5.1);
--- Increasing the polymer concentration is calculated (see Chapter 11);
--- Increased Hagenbach correction;
--- No precision content.

Polyamide plastic
Part 1. Determination of viscosity number
1 Scope
GB/T 12006 provisions of this part of the determination of the solvent in certain provisions of polyamide dilute solution viscosity number.
Polyamide samples should be completely dissolved in the selected solvent. Additives such as flame retardants and modifiers, etc. often affect viscosity test, formic acid
The cause high viscosity number, low viscosity in sulfuric acid causes the number. The degree of influence depends on the polyamide compound additive, additive content, save
In some of the other additives and formulations and other conditions.
For pure polyamide or polyamide containing no additive effect on the viscosity of the test, which measures the viscosity of a polymer molecule is provided
The amount of test methods. Pure polyamide or polyamide containing no additive effect on the viscosity of the test, the viscosity of a solvent from converting to another
Solvents.
Additive-containing polyamide, the impact of additives on viscosity test, which should indicate that the viscosity of the solvent and material composition used. This situation
By measuring the viscosity of the solvent can not be converted from one to another solvent.
This method is applicable according to ISO 1874-1 named PA46, PA6, PA66, PA69, PA610, PA612, PA11, PA12,
PA6T/66 under, PA6I/6T, PA6T/6I/66, PA6T/61, PA6I/6T/66 and PAMXD6 polyamide, and in any conditions
Copolyamides can be dissolved in a solvent, a polyamide compound and a polyamide other provisions.
This method does not apply lactam anionic polymerization generated or generated by the cross-linking agent polyamide, such polyamide generally insoluble in provisions
Solvent.
Viscosity of specific conditions in compliance with the provisions of this section in accordance with the general procedure GB/T 1632.1-2008 prescribed determined.
