摘要： A fine-particle, free-flowing rubber powder containing silicatic fillers, one or more organosilanes having trialkoxysilyl groups, and a rubber prepared by solution polymerization is prepared by a process that starts from a two-phase system: 1) filler in water, and 2) rubber in organic solvent. A rubber/silicatic filler/silane composite is formed during transfer, under gentle conditions, of the various reactants into a single phase. The process features a high degree of freedom in selecting forms of filler and in selecting the organosilane and gives a finished rubber powder in which a silicatic filler and an organosilane have undergone complete chemical reaction.

摘要： A process is provided for making a carbon-filled rubber having a uniform dispersion of nanometric-sized carbon black particles. Fluffy carbon black is received as a slurry in water and added to latex rubber before or during coagulation in an emulsion styrene butadiene rubber plant, or fluffy carbon black is similarly incorporated in rubber using a different type of rubber-manufacturing process. A uniform dispersion of smaller-than-usual carbon black particles in rubber is formed, which provides a black masterbatch rubber with superior mechanical and rheological properties. Ash and grit is removed from the fluffy carbon black slurry, which further improves the properties of the carbon-filled rubber by reducing defects in the rubber caused by the ash or grit.

摘要： A printing machine for recording an image on a recording medium with marking particles, wherein process of making marking particles includes a method for dispersing pigment aggregates in a solution. The method employs an ultrasonic device to efficiently breakup particle agglomerates by driving the ultrasonic signal over a small range of frequencies around the acoustic slow wave frequency of the saturated agglomerate. At this frequency, the fluid vibrates out of phase with the solid and is forced out through the pore structure in the agglomerate. This relative fluid motion to exert high viscous stresses at the particle-particle contact points which leads to fracture of the agglomerate.

摘要： There is described a process for producing a particulate composition comprising the steps of: (a) forming a first dispersion comprising first particles stabilised in a first fluid by a first species in an initial state, the first species changeable between the initial state and a further state, where the initial state provides (directly or indirectly) more stability to the particles within the dispersion than the further state; (b) optionally the step of forming a second dispersion comprising second particles stabilised in a second fluid, miscible with the first fluid, by a second species in the, or another, initial state, the second species also changeable between the, or another ,initial state and the, or another, further state, where said initial state provides (directly or indirectly) more stability to the particles within the dispersion than said further state; (c) after the optional step of mixing the first and second dispersions together if the second dispersion was formed in step b), changing the state(s) of the first and/or optionally second species from the initial state(s) to the further state(s) substantially to induce association between the dispersed particles to form clusters; and (d) binding together the particles within the clusters. A preferred embodiment of the process comprises mixing together two aqueous dispersions of particles (e.g. pigment particles with particles of latex polymer formed by emulsion polymerisation). The dispersions are stabilised by ionic surfactants of same sign charge. Association of the particles into clusters is induced by adjusting pH to selectively protonate or deprotonate the surfactants. The clusters are grown by aggregation into loose matrices which are fused together to form particles which can be used in electroreprographic toners.
