A coated electrical accessory includes a bare electrical accessory and a substantially inorganic and dried coating layer coating the bare electrical accessory. The coating layer includes a heat radiating agent and a binder. When the coated electrical accessory is tested in accordance with ANSI CI 19.4-2004 with an amount of imparted current, the coated electrical accessory exhibits an operating temperature that is less than an operating temperature of a bare electrical accessory tested in accordance with ANSI CI 19.4-2004 with the same amount of imparted current. Methods are also provided.

摘要:
A system and a process for continuously electrolytically coating a light metal coil is provided. The system includes a bath containing a precursor for an electroceramic coating on a light metal coil and containing a cathodic connection, at least one motor connected to at least one motive assembly to impart movement to the coil. A power source provides voltage and current to the coil through the electrification device, and through the coil in the bath to the cathode connection via the aqueous electrolytic solution. The process includes electrifying bare coil with a voltage and a current, passing the electrified bare light metal coil through a bath having a cathodic connection and containing an aqueous solution with a precursor for an electroceramic coating, and electrochemically reacting the light metal coil with the precursor thereby generating a coated light metal coil having an electroceramic coating on at least one surface.

A skinning apparatus (100) and a method of skinning a porous ceramic (110). The apparatus includes an axial skinning manifold (108). The axial skinning manifold (108) includes a curved adaptive pipe (128) to flow cement in a circumferential direction (C) from an inlet at a first position and through an adaptive opening (136) along an inner bend of the curve through a land channel (140) disposed along the inner bend. The land channel (140) emits the cement at a constant velocity from a land opening (142) extending proximate the first position to a second position spaced apart from the first position. The land outlet (142) emits cement at a constant velocity around the outer periphery of the porous ceramic (110) to dispose a uniform skin thereon as the porous ceramic (110) moves axially relative to the land outlet (142).
摘要:
The invention provides a coating process for electrical steel sheet using a varnish composition, comprising the steps of a) applying at least one coating layer of a varnish composition onto the surface of the electrical steel sheet wherein the varnish composition comprises (A) 1 to 95 wt% of at least one resin comprising nucleophilic groups selected from the group consisting of OH, NHR, SH, carboxylate and CH-acidic groups, and electrophilic groups which can react with the above mentioned nucleophilic groups, wherein the resin is capable of transacylation in its main chain and/or side chain(s), (B) 5 to 75 wt% of at least one organic solvent and/or water, (C) 0 to 40 wt% of at least one resin different from (A), (D) 0 to 10 wt% of at least one customary additive, (E) 0 to 40 wt% of at least one pigment, filler and/or nano-scaled particle and/or monomeric and/or polymeric element-organic compound, wherein the wt% based on the total weight of the varnish composition. b) curing the applied at least one coating layer. Reduced energy consumption while curing the coating and reduced or no formaldehyde generation upon curing can be provided.
