Abstract
Milling/sizing apparatus (12) which includes individual and/or nested sieves (20) each of which may also include a quantity of beads, disks and/or other geometric or non-geometric shapes (56). The sieves (20) can be rotated, vibrated or agitated in any and all combinations by various methods to achieve independently horizontal rotation and vertical reciprocation (similar to a merry-go-round) to efficiently segregate, size or mill cohesive and polydisperse powder particles to specific size ranges. The invention also contemplates a method for using the apparatus in the sizing and quantification of aggregated particles of cohesive disperse powders.
Description
- The thermoplastic (co) polymers B contain from 50 to 99, preferably from 60 to 95 parts by weight of B.l and from 50 to 2, preferably from 40 to 5 parts by weight of B.2. Particularly preferred (co) polymers B are those consisting of styrene with acrylonitrile and, if appropriate, methyl methacrylate, of a-methylstyrene with acrylonitrile and, if appropriate, methyl methacrylate or styrene and a-methyl styrene with acrylonitrile and if appropriate with methyl methacrylate. The styrene-acrylonitrile copolymers according to component B are known and can be prepared by radical polymerization, in particular by emulsion, suspension, solution or bulk polymerization. The copolymers according to component B preferably have molecular weights W w (weight average, determined by light scattering or sedimentation) of between 15,000 and 200,000. Particularly preferred copolymers B according to the invention are also copolymers which are statistically made from styrene and maleic anhydride, which can be obtained by mass polymerization or continuous solution with incomplete conversions from the monomer correspondent. The proportion of both components of the ethylene-maleic anhydride copolymers statistically constituted, suitable according to the invention, can vary within wide limits. The preferred content of maleic anhydride is from 5 to 25% by weight. The molecular weights (number average M n) of the styrene-maleic anhydride copolymers, statistically constituted, suitable according to the invention, according to component B can vary within wide limits.
The range from 60,000 to 200,000 is preferred. For these products, a limit viscosity of 0.3 to 0.9 is preferred (measured in dimethylformamide at 25 [deg.] C., cf. Hoffmann, Krómer, Kuhn, Polymeranalytik I, Stuttgart 1977, pages 316 et seq.). Instead of styrene, the vinyl (co) polymers B may also contain styrene-substituted nuclei such as p-methylstyrene, vinyltoluene, 2,4-dimethylstyrene and other substituted styrenes such as α-methylstyrene, which may also be optionally available. halogenated (preferably with chlorine and / or bromine). Component C. The graft polymers C comprise, for example, graft copolymers with rubber-elastic properties, which can essentially be obtained from at least two of the following monomers: chloroprene, butadiene-1,3, isoprene, styrene , acrylonitrile, ethylene, propylene, vinyl acetate and esters of (meth) acrylic acid with 1 to 18 carbon atoms in the alcohol component; ie polymers such as those described for example in "Methoden der Organischen Chemie", (Houben-Weyl), volume 14/1, Georg Thieme-Verlag, Stuttgart 1961, pages 393-406 and in C.B. Bucknall, "Thoughened Plastics", Appl. Science Publishers, London 1977.

Obtaining and testing the molding compositions according to the invention. The mixing of the components is carried out in an internal 3-liter kneader.

The specimens are subjected to a previous dilation by means of an arc-circle template (1.2 to 2.4% previous dilation) and stored in the test medium at room temperature. The behavior to the iron under tension is evaluated by the formation of cracks in function of the dilation - either before or after the break as a function of the time of exposure in the test medium.
The expansion at break DR is determined within the scope of the determination of the tensile modulus E according to the ISO 527 method in support bars F3. The determination of the hot dimensional stability according to Vicat B is carried out in accordance with DIN 53460 or ISO 306. The composition of the tested materials and the data obtained are summarized in table 1 below.

It can be seen that the SiO2 improves the dilatation to the romra, the behavior - Vicat and the ESC behavior, improving in a particularly marked way the dilation to the ridge, especially when hydrophilic SiO2 (component D.l) is used. It is noted that, with reference to this date, the best method known to the applicant, to carry out the aforementioned invention, is the conventional one for the manufacture of the objects referred to therein.
