摘要:
An electric energy regulating device for coupling to a battery of a transportation device and for regulating electric energy, includes a circuit board having two conductors for coupling to two electrodes of the battery, one or more electrolyte capacitors and one or more porcelain capacitors coupled between the conductors for receiving and supplying electric energy, or for absorbing impedance and inductance, and one or more EPROMs coupled between the conductors for controlling the circuit board to supply a stable electric energy to the electric facilities of the transportation device. One or more MEF capacitors may be coupled between the conductors for absorbing noises and electric shocks.

A process for the preparation of pigmented toner compositions comprising: a) forming at a first temperature, a first melt mixture comprised of a partially crosslinked thermoplastic resin, pigment, optionally a wax, and optional additives, wherein the partially crosslinked thermoplastic resin is comprised of a mixture of crosslinked resin macrogel particles, crosslinked resin microgel particles, and uncrosslinked resin; and b) melt mixing at a second temperature, the first melt mixture to form a second mixture, wherein the macrogel particles are partially converted into microgel particles, and wherein the second temperature is less than or equal to the first temperature.
摘要:
A one step process for the preparation of toner compositions which comprises adding to an extruder a base resin, initiator, pigment, and optional charge enhancing additive; effecting crosslinking of the base resin in the extruder to provide a toner comprising a pigment, optional charge additive and crosslinked resin comprising linear portions and crosslinked portions; and wherein said crosslinked portions are comprised of densely crosslinked microgel particles.
摘要:
Developer compositions with toner compositions comprised of suspension polymerized styrene butadiene polymers, pigment particles, magnetites, and charge enhancing additives; and carrier components comprised of a carrier core with a coating thereover comprised of a polymer mixture with from about 10 to about 90 percent by weight of a first polymer, and from about 90 to about 10 percent by weight of a second polymer, which first and second polymers are not in close proximity in the triboelectric series.
摘要:
A process for preparing an electrophotographic toner composition which comprises premixing a pigment and a charge control additive in the absence of a solvent, subsequently admixing the premixed pigment and charge control additive and a resin, and extruding the pigment, charge control additive, and resin. The pigment and the charge control additive may be premixed prior to being added to the extruder with the resin; alternatively, the pigment and charge control additive may be premixed by adding them to the extruder via an upstream supply means and extruding them, and subsequently adding the resin to the extruder via a downstream supply means.

摘要:
The presently disclosed embodiments relate in general to toners for use in electrophotographic apparatuses, such as printers and copiers. More particularly, a toner formulation of at least one binder, at least one colorant, and an embrittling agent, and methods for making the same, is provided wherein the embrittling agent increases grinding rate of the toner formulation.
摘要:
Toners including a low melt wax and a carnauba wax are described. The toners include at least one binder, at least one colorant, at least one wax having a melting point of 135° C. or less, and a compatibilizer wax (e.g., carnauba wax). The low melt wax is preferably polyethylene wax. Images may be formed with the toners in an image forming process including steps of depositing the toner onto a latent image of an imaging member to form a toner image, transferring the toner image to an image receiving substrate, and fusing the toner image. During the fusing, the at least one wax and the compatibilizer wax exude from the toner, forming a stripping enhancing layer upon the toner image. Thus, fuser roll stripping performance is enhanced.
摘要:
Toner particles are prepared by a process comprising providing an extrusion apparatus; adding resin particles and additive particles to a supply means in the extrusion apparatus; adding the resin particles and the additive particles to a blending chamber in the extrusion apparatus, which blending chamber is maintained at a temperature of from about 50° C. to about 120° C.; blending the resin particles and the additive particles to form a mixture; extruding the resin particles to form extruded material; injecting liquid substances, which have a lower boiling point than the melt temperature of the resin particles, into the blending chamber during extrusion without the application of a vacuum to remove the liquid substances prior to extrusion; and grinding the extruded material to form toner particles.
