    1、Designation: D 5461 06Standard Test Method forRubber Compounding MaterialsWet Sieve Analysis ofPowdered Rubber Compounding Materials1This standard is issued under the fixed designation D 5461; the number immediately following the designation indicates the year oforiginal adoption or, in the case of

    2、revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers a procedure for the qualitativeevaluation of aggregate size and aggrega

    3、te size distribution ofpowdered rubber accelerators and other compounding materi-als which are insoluble in water.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 This standard does not purport to address all of thesafet

    4、y concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Terminology2.1 Definitions:2.1.1 aggregatea cluster of individual particl

Summary of Test Method3.1 A sample of powdered rubber chemical is wet

    6、ted with adilute aqueous solution of soap and defoamer. The sample istransported by water flow through stacked sieves arranged inorder of decreasing mesh size. The material retained on theface of each sieve is dried in an oven. The dry mass of retainedmaterial is obtained for each sieve. The percent

    7、 retainedmaterial is calculated on the basis of original sample mass.Individual masses and percentages are summed to evaluate theaggregate size distribution for the sample.4. Significance and Use4.1 This test method is used to evaluate the suitability ofpowdered rubber chemicals, particularly accele

    8、rators, for usein rubber compounds that require very small particle clusters toachieve a uniform cross-linked network. This test method isintended to be used to ensure that no excessively large particlesare present that would result in network “flaws” and todetermine that the powdered product follow

    9、s a typical patternof size distribution.4.2 In view of the inherent variability in this type of method,it is recommended that the results be used only in a semi-quantitative sense; that is, comparisons within a laboratory orrelative comparisons of samples against reference samples, orboth.5.

A pinch-clamp serves as a control valve.7.2 Assemble pre-cleaned sieves (200 or 76 mm) into astack, with the largest sieve opening on top.

Absence of foam, bubbles,and visible chunks indicates complete wetting.7.9 Pour the contents of the bottle onto the top sieve in thesieve stack. Ensur

Switch to an aerated stream of waterto finish washing the sample through the sieve. If necessary,alternate the use

(Clean the brush with water oversieve.)7.11 When transfer is complete, wash the residue to themiddle of the sieve with a gentle stream of water. Take care toensure

    21、 that all soap residue is rinsed from the remainingsample.7.12 Remove the top sieve from the stack and wipe excesswater from the sieve sides and bottom with a dry lint-freeabsorbent towel and set aside.7.13 Repeat 7.10 through 7.12 for all sieves in the stack.7.14 Dry each sieve plus residue in a 70

(Low melting materials should be dried at 10C belowthe melting point.)7.15 Remove the sieves from the oven and allow them tocool to ambient temperature.7.16 Remove the residue from the sieve by gently tappingthe sides while pouring the solids into a tared, properly labeleda

    23、luminum weighing dish.NOTE 2It may be possible to avoid this transfer when using thesmaller 76 mm sieves. In that case, the sieves should be tared initially, thenreweighed following drying and cooling to ambient temperature.7.17 Record the quantity of residue contained on each sieve.8. Calculation8.
