23、pecifies a method for the determination of the tendency for the mixing of two different coating powdersto result in the deterioration of the surface quality of the final coating. The results depend on the followingcharacteristics of the coating powders:a) their chemical reactivity;b) their chemical

24、composition;c) their melt properties.The onset of the deterioration in appearance, its nature and its extent will depend greatly on the ratio inwhich the powders are mixed.The test is useful in predicting the possibility of incompatibility arising from mixing different powders bothduring the manufac

25、turing process and during the application of the coating powder.The nature of the deterioration in surface appearance may manifest itself in various ways, including:- change in gloss level;- the presence of pinholes, including micro-pinholes;- the appearance of orange peel;- the presence of craters;

26、- the presence of bittiness (graininess);- the presence of colour contamination.NOTE Deterioration in mechanical properties may also be experienced. However, this part of ISO 8130 isonly concerned with changes in appearance.DIN EN ISO 8130-12:2011-02 EN ISO 8130-12:2010 (E) 4 2 Normative referencesT

All standards are subject torevision, and parties to agreements based on this part of ISO 8130 are encouraged

28、 to investigate thepossibility of applying the most recent editions of the standards indicated below.

29、ISO 2813:1994, Paints and varnishes Determination of specular gloss of non-metallic paint films at 20,60 and 85.3 PrincipleThe coating powders are mixed together in a range of ratios and each mixture is applied to standard testpanels, stoved and the surface inspected for evidence of incompatibility.

30、4 ApparatusOrdinary laboratory apparatus, together with the following:4.1 Clean and degreased steel panels, as described in ISO 1514, with holes drilled at one end forhanging.4.2 Powder spray system, consisting of a corona charge gun or a tribo charge gun and an air extractionspray booth with a suit

31、able powder collection device.4.3 Suitable clean container, capable of holding a mass of the powder suitable for processing in thespray system (4.2).NOTE Plastic bags have been found to be suitable for non-metallic powders.4.4 Balance, accurate to 10 mg.4.5 Oven, capable of stoving the coated test p

32、anels.5 SamplingPrepare a representative sample of the powder under test, as described in ISO 8130-9. The quantity ofpowder required will depend on the powder spray system (4.2).NOTE A quantity of between 10 g and 200 g is normally suitable for each test.5 DIN EN ISO 8130-12:2011-02 EN ISO 8130-12:2

33、010 (E) 6 ProcedureCarry out the test in duplicate.6.1 In the absence of agreement between the interested parties, prepare mixtures in the following massratios in a quantity required for the test, weighing each component to an accuracy of 10 mg:Powder A 100,0 99,9 99,0 90,0 50,0 10,0 1,0 0,1 0,0Powd

34、er B 0,0 0,1 1,0 10,0 50,0 90,0 99,0 99,9 100,06.2 Place each of the samples prepared in 6.1 in a clean container (4.3) and agitate for sufficient time toensure complete homogenization.NOTE Vigorous shaking by hand of a partially filled container for 15 s to 30 s has proved to be adequate.6.3 Spray

35、each of the mixed samples onto a test panel (4.1), using the spray gun (4.2), to a thicknessappropriate to the application.It is extremely important that the spraying apparatus is thoroughly cleaned between each application. In anycase, it is mandatory that the order of application of the samples be

36、 in increasing order of each minorconstituent, thus:100,0 A : 0,0 B to 50,0 A : 50,0 Band then:100,0 B : 0,0 A to 90,0 B : 10,0 A.6.4 Place the coated panels in the oven (4.5) and stove in accordance with the prescribed stovingschedule of the slower-reacting component. If no schedule is available, i

37、t shall be agreed on between theinterested parties.6.5 Remove the panels from the oven and allow to cool.6.6 Examine the coated surfaces for pinholes, craters and other imperfections.NOTE Where appropriate, a quantitative measure of change in gloss may be obtained by measuring glossvalues in accorda

38、nce with ISO 2813.7 Expression of resultsA verbal description of the appearance of the coatings will be sufficient for the purposes of this standardmethod. Where quantitative measurements of gloss have been undertaken, these shall be quoted numerically.NOTE As very small amounts of contamination can

39、 greatly influence the level of gloss, it may be useful toplot the gloss measurements graphically. In this case, it is recommended that a probability chart be employedin which the gloss measurements are plotted as abscissae and the mass ratios of the powders in the mixtureare plotted as a probabilit

40、y distribution on the ordinate scale. In this way, it is possible to obtain acompatibility curve in which the influence of small concentrations of one powder on the other are clearlydemonstrated.DIN EN ISO 8130-12:2011-02 EN ISO 8130-12:2010 (E) 6 8 PrecisionPrecision data are inappropriate for non-

41、quantitative measurements. The precision of any glossmeasurements shall be as detailed in ISO 2813.9 Test reportThe test report shall contain the following information:a) all details necessary to identify the products tested;b) a reference to this part of ISO 8130 (ISO 8130-12);c) the recommended st

42、oving schedule for each powder;d) the stoving schedule used in the test, if no schedule is available (see 6.4);e) the gun used, i.e. either corona or tribo (see 4.2);f) the coating thickness;g) the results of the test as indicated in clause 7;h) any deviation from the test method specified;i) the date of the test.7 DIN EN ISO 8130-12:2011-02 EN ISO 8130-12:2010 (E)
