摘要： Aluminum zinc phosphate hydrates or basic aluminum zinc phosphate hydrates are manufactured by reacting 1 mole of aluminum hydrogen phosphate with from 2.4 to 4 moles of zinc oxide, if necessary with the addition of up to 0.4 moles of alkali aluminate or the equivalent quantity of alkali hydroxide. A 50% by weight acidic aluminum hydrogen phosphate solution is preferably used for the reaction which is carried out at an elevated temperature in the range from 30.degree. to 80.degree. C. The aluminum zinc phosphate hydrates produced by the method are useful anti-corrosion pigments for use in paints.

摘要： Permanently non-dusting pigment and dye preparations, which contain as dedusting agents,(a) a surface-active substance in an amount of from 0.5 to 10%, and(b) a substance which after mixing of the dried mixture of pigment and surface-active substance causes the mixture, upon repeated intensive shear stress, to reach the smear point, contained in an amount (depending on the fineness, morphology and later intended use of the pigment and dye preparations) of from 2 to 25%, the remainder comprising the pigment or dye, wherein the preparations can be obtained by adding to the filter suspension of the pigment or dye a surface-active substance, or mixtures thereof, which is or are suitable in accordance with the type of pigments or dyes and with the particular intended use, and after homogeneous distribution the combination of pigment and surface-active substance, optionally after isolation in the form of a press cake, is dried, and the dried product is subsequently added to an agent which is liquid and flowable or becomes liquid at an elevated temperature, which upon intensive shear stress causes the mixture to reach the smear point, mixing is performed applying an intensive shear stress, until the smear point is reached, and then granulation is subsequently performed, in a manner known per se, if needed; and a dust measuring device in which the conditions leading to dust production are maintained during the entire measuring operation.

摘要： The dust producing properties of a pigment or dye are measured under conditions which close approximate those during handling. A vessel with baffles having pigment or dye therein is rotated for a specified time while air is drawn through the rotating vessel by a specified amount of vacuum applied downstream of the vessel. The baffles disturb the pigment or dye in the vessel, creating dust particles which are entrained in an airstream created by the vacuum. Larger particles trapped in this vacuum are removed by a separator, while the dust particles are trapped in the airstream are trapped by a filter. The dusting properties of the pigment or dye in the vessel may then be determined by weighing the filter.

摘要： Plastics are described which contain, in intimate contact with the pigments, boric acid in a quantity of 1 to 20% by weight, preferably 2 to 15% by weight, of the dry pigment. Also described is the process for producing said plastics, in which the usual plastic granules or powders are mixed with the above-mentioned quantities of boric acid before, during or after addition of the pigment, and the boric acid is brought into intimate contact with the pigment before further processing, of the particulate plastic is mixed with the pigment containing the above mentioned quantities of boric acid before being subjected to further processing under thermal stress.
