Pigmentet dhe shtesa - Metodat e dispersionit dhe vlerësimi i dispersibilitetit në plastikë - Pjesa 3: Përcaktimi i vetive ngjyruese speciale dhe lehtësia e dispersionit të pigmenteve të zeza dhe me ngjyrë në polietilen me anë të një mulliri me dy cilindra

Pigments and extenders - Methods of dispersion and assessment of dispersibility in plastics - Part 3: Determination of colouristic properties and ease of dispersion of black and colour pigments in polyethylene by two-roll milling

Scope

This part of EN ..... specifies a method of determining in polyethylene (PE) the colouristic properties of a test pigment relative to a standard, and the ease of dispersion DH/PE of pigments from the differences in colour strength on dispersing colouring materials under various conditions. The method is appropriate for use with organic and inorganic black and colour pigments.
