17、NISO813014:2004 ii ENISO813014:2004 iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bod

18、y interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrote

19、chnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by

20、 the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rig

21、hts. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8130-14 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes. ISO 8130 consists of the following parts, under the general title C

25、al terms used in the field of coating powders. Other terms and definitions related to paints and varnishes are given in ISO 4618, Paints and varnishes Terms and definitions for coating materials. 2 Terms and definitions 2.1 agglomeration condition in which individual particles become joined together

26、 into larger assemblies 2.2 back ionization electrostatic rejection electrostatic repulsion dielectric breakdown in an electrostatically deposited powder caused by an excess accumulation of charge NOTE The phenomenon is associated with the disruption of the layer, leading to surface defects and to t

27、he eventual disintegration of the coating. 2.3 charge-to-mass ratio ratio of the electric charge on a powder sample to its mass NOTE A ratio of at least 10 4Ckg 1is normally required for acceptable coating performance. 2.4 classification division of a powder sample into two fractions, one above, the

28、 other below a predetermined particle size 2.5 coating powder finely divided particles of resin, either thermoplastic or thermosetting, generally incorporating pigments, fillers (extenders) and additives, and remaining finely divided during storage under suitable conditions, which, after fusion and

29、possibly curing, give a continuous film 2.6 compaction agglomeration of particles under pressure ENISO813014:20042 2.7 deposition efficiency proportion of the mass of powder deposited on a substrate compared to the mass of powder sprayed 2.8 electrostatic fluidized bed apparatus which allows a powde

30、r sample to be fluidized and which, at the same time, has a means of electrically charging the powder particles NOTE The charged powder forms a cloud above the bed and will deposit on an earthed article brought in contact with it. 2.9 electrostatic rejection electrostatic repulsion See 2.2 back ioni

31、zation 2.10 electrostatic spraying powder application process in which the powder particles are given an electric charge resulting in their attraction to an earthed workpiece 2.11 Faraday cage effect prevention of charged particles from entering and properly covering corners or recesses, due to the

32、diversion of electric force lines to more accessible ground points, during electrostatic spraying 2.12 fines particles having a size below an accepted minimum value NOTE The fines are often regarded as the reject portion from a grinding process. 2.13 gelation conversion of a molten coating powder in

33、to a non-flowing state NOTE Gelation will occur at the instant the curing process changes the material into a three-dimensional structure. 2.14 gel time time taken for a specified volume of coating powder to become non-deformable, under specified conditions, after melting 2.15 hybrid coating powder

34、powder product based on the fusion of different resin species in which part or all of the crosslinking reaction occurs between the functional groups of the resins 2.16 impact fusion tendency of finely divided powder particles to fuse when in high-speed contact with other particles in the application

35、 equipment during the spraying process 2.17 inclined-plate flow inclined-plane flow measurement of the flow characteristics of a molten thermosetting coating powder down a plane inclined at a set angle to the horizontal ENISO813014:2004 32.18 incompatibility tendency of the mixing of two different c

38、 a size above a stated maximum value NOTE The oversize is often regarded as a reject portion from the grinding process. 2.23 particle size linear dimensions of particles of coating powders NOTE 1 The particle size is usually quoted as a mean value. NOTE 2 Coating powder particles are irregular in sh

39、ape and, consequently, size data will only have any value if qualified by reference to the specific method of measurement. 2.24 particle size distribution spread of particle sizes in a given sample of powder, expressed as a sequence of percentage masses, or volumes, of particles lying between given

40、sizes 2.25 powder blocking agglomeration of coating powder so as to render it unsuitable for application 2.26 powder coating protective and/or decorative coating formed by the application of a coating powder to a substrate and fusion (and curing, if necessary) to give a continuous film 2.27 powder f
