1 Scope

This part of GB/T 1632 specifies a method for determining the viscosity (also known as reduced viscosity) and relative viscosity in a dilute solution of polycarbonate: This section applies to polycarbonate (PC) pure materials and blends and mixtures with or without other fillers:

2 Normative references

The following documents are indispensable for the application of this document: For dated reference documents, only the dated version applies to this article Pieces: For undated references, the latest version (including all amendments) applies to this document: GB/T 1632:1-2008 Plastics use capillary viscometer to determine the viscosity of polymer dilute solutions Part 1: General rules (ISO 1628-1:1998, IDT) GB/T 11415-1989 Laboratory sintered (porous) filter pore size, classification and grade (ISO 4793:1980, NEQ) GB/T 30514-2014 glass capillary kinematic viscometer specifications and operating instructions (ISO 3105:1994, MOD)

3 Definitions and units

The definition of the viscosity number VN (in mL/g) is shown in formula (1): VN=η -η0 η0c νρ-ν0ρ0 ν0ρ0c νρ ρ0 -ν0 ν0c = ν-ν0 ν0 (1) Where: η --- the dynamic viscosity of the solution, in Pascal seconds (Pa s); η0 --- the dynamic viscosity of the solvent, in Pascal seconds (Pa s); ρ ---The density of the solution, in kilograms per cubic meter (kg/m3); ρ0 ---Solvent density, in kilograms per cubic meter (kg/m3); ν=η/ρ --- kinematic viscosity of the solution, in square meters per second (m2/s); ν0=η0/ρ0---solvent kinematic viscosity, in square meters per second (m2/s); c --- The mass concentration of the polymer solution, in grams per milliliter (g/mL): Since the difference between the density ρ of the solution and the density ρ0 of the solvent is very small, the η in the formula for calculating the reduced viscosity can be replaced by ν: Solution The relative viscosity ηrel (dimensionless), defined in formula (2): ηrel= ν0 (2) Where: ν=η/ρ --- kinematic viscosity of the solution, in square meters per second (m2/s); ν0=η0/ρ0---Kinematic viscosity of the solvent, in square meters per second (m2/s):
