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

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.

Pigmente und Füllstoffe - Dispergierverfahren und Beurteilung der Dispergierbarleit in Kunststoffen - Teil 3: Bestimmung der koloristischen Eigenschaften und der Dispergierhärte von Schwarz- und Buntpigmenten in Polyethylen im Walztest

Dieser Teil von EN ... legt ein Verfahren zum Bestimmen der koloristischen Eigenschaften eines zu prüfenden Pigmentes in Polyethylen (PE) im Vergleich zu einem Standard fest sowie zum Bestimmen und der Dispergierhärte DHpe von Pigmenten aus den Farbstärkeunterschieden beim Dispergieren von Farbmitteln bei unterschiedlichen Bedingungen. Das Verfahren ist für organische und anorganische Schwarz- und Buntpigmente geeignet.

Pigments et matieres de charge - Méthodes de dispersion et évaluation de l'aptitude a la dispersion dans les plastiques - Partie 3: Détermination des propriétés colorimétriques et de la facilité de dispersion des pigments noirs et colorés dans le polyéthylene par calandrage sur bicylindre

Cette partie de la présente Norme européenne prescrit une méthode permettant de déterminer dans le polyéthylene (PE) les propriétés colorimétriques d'un pigment d'essai par rapport a un étalon, ainsi que la facilité de dispersion DHPE des pigments a partir des différences d'intensité de couleur lorsque des matieres colorantes sont dispersées dans différentes conditions.
La méthode A convient pour les pigments organiques en poudre et pour les pigments au noir de carbone sous forme de poudre, qui sont, dans un grand nombre de cas, sujets au compactage (réagglomération sous pression) ; elle peut également etre utilisée avec les pigments inorganiques en poudre et avec les préparations de pigments, en poudre ou sous forme de flocons.
La méthode B est appropriée aux essais de pigments et de préparations de pigments sous forme granulaire ainsi qu'aux essais de pigments inorganiques quelle que soit leur forme.
La facilité de dispersion déterminée de cette maniere n'est valable que pour l'équipement, les conditions et le milieu de dispersion utilisés. Des conditions d'essai différentes de celles spécifiées peuvent entraîner des résultats différents ; cela s'applique aussi bien a la valeur absolue de la facilité de dispersion qu'a la relation entre les différentes valeurs des divers pigments. L'indice DHPE est donc utilisé pour désigner la valeur obtenue conformément a la présente partie de la Norme.

EN 13900-3:2003 (E)31 ScopeThis part of this European Standard specifies a method of determining in polyethylene (PE) the colouristic propertiesof a test pigment relative to a standard, and the ease of dispersion DHPE of pigments from the differences in colourstrength on dispersing colouring materials under various conditions.Method A is appropriate for use with organic powder pigments and carbon black pigments in powder form, many ofwhich are subject to compaction (reagglomeration under pressure), for inorganic pigments in powder form and forpigment preparations in powder or flake form.Method B is appropriate for testing pigments and pigment preparations in granular form and for inorganic pigmentsin any form.The ease of dispersion determined in this way is valid only for the dispersion equipment, dispersion conditions anddispersion medium being used. The use of test conditions differing from those specified may give different results; thisapplies both to the absolute magnitude and to the relation between values of the ease of dispersion of variouspigments. The subscript DHPE is therefore used to designate the value obtained as specified in this part of thisEuropean Standard.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

The DHPE is derived from the increase in colour strength achieved by two-rollmilling as specified in 8.2, relative to the colour strength achieved as specified in 8.14 PrincipleUsing a two-roll mill, the pigment under test is dispersed at an appropriate temperature in the polymer. The cooledmilled sheet obtained in this way is then subjected to the higher shearing forces resulting from two-roll milling at anarrower gap width. The resulting increase in colour strength (see EN 12877-1) is a measure of the ease of dispersionDHPE.SIST EN 13900-3:2003
