    Abstract: A process for electrostatically applying a multilayered coating on a substrate in one operation or step is disclosed, wherein a mixture of powders of at least two different coating materials is used as the coating composition, each powder, in the case of nonconducting powders, differing from the others in dielectric constant by a factor of at least 0.1, and the powders being of substantially different specific gravities, with the components having the lowest dielectric constant value having the lowest specific gravity value. At least one of the powders will be a powder of a film-forming non-conductive organic or inorganic polymer. Upon electrostatically applying a coating of this powdered composition to a conductive substrate which has a neutral charge or a charge opposite from that of the coating composition powder particles, the powders stratify into distinct layers of different compositions. The powders adhere to the substrate because of contact or static electrification for a reasonable length of time and until at least one of the powders can be cured or fused to form the final coating. Thus, for instance, in only one pass with an electrostatic spray gun, a protective coating of superimposed layers of zinc, epoxy, and polyethylene can be applied to a conductive substrate.

    Abstract translation: 公开了一种在一个操作或步骤中将多层涂层静电涂覆在基底上的方法，其中使用至少两种不同涂层材料的粉末的混合物作为涂料组合物，在非导电粉末的情况下，每种粉末， 不同于其他介电常数至少为0.1的因子，并且粉末具有基本不同的比重，其中具有最低介电常数值的组分具有最低的比重值。 至少一种粉末将是成膜非导电有机或无机聚合物的粉末。 在将这种粉末状组合物的涂层静电施加到具有与涂料组合物粉末颗粒相反的中性装料或电荷的导电基材上时，粉末分层成不同组成的不同层。 由于接触或静电充电合适的时间长度，直至粉末中的至少一种可以固化或熔化以形成最终的涂层，因此粉末粘附到基底上。 因此，例如，在仅有一次通过静电喷枪的情况下，可以将锌，环氧树脂和聚乙烯叠加层的保护涂层施加到导电基板上。

    Abstract: A magnet wire is prepared by first passing a copper wire through a dense cloud of electrostatically charged and finely divided plastic particles such as epoxy powder held within a confined chamber and being created by a spray gun positioned within the chamber and below the elongated member and in combination with a fluidized bed of a similar or a different plastic powder and then passing the electrostatically coated wire through an oven maintained at a temperature sufficiently high to fuse the electrostatically deposited plastic particles thereon to form an insulation film on the wire.

    Abstract: The present invention discloses a hydrate energy-storage temperature-control material and a preparation method therefor. The material includes a refrigerant hydrate and a cross-linked polymer. The preparation method comprises the following steps: first, preparing a refrigerant hydrate by using a high-pressure reactor, and conducting grinding, crushing and sieving to obtain hydrate particles; then, uniformly spraying polytetrafluoroethylene suspended ultrafine powder onto the surface of the hydrate particles by using an electrostatic spraying device, and putting the hydrate particles into a plasma instrument to modify polytetrafluoroethylene so as to allow free radicals to be formed on the polytetrafluoroethylene powder surface; finally, subjecting monomers to graft polymerization with the free radicals on the polytetrafluoroethylene surface under the irradiation of a high-pressure mercury lamp of UV lighting system to stabilize the structure of the material, preparing a final product. According to the present invention, a hydrate energy-storage temperature-control material with good stability is prepared. A method capable of preparing various types of refrigerant hydrate materials is provided. The product can give full play to the advantages of hydrate energy storage and temperature control, can be periodically used, and can be used in various fields such as building, refrigeration, etc.
