    Abstract: A method for depositing a liquid on a substrate by directing an elongated linear flow of a liquid (647) toward a substrate (670), and impinging a flow of fluid against the liquid to atomize the liquid and deposit liquid droplets on the substrate. Excess mist is collected in a collector device (650), which is provided with a paddlewheel or auger to help move mist into and through the collector. Heated air may also be introduced into the collector. Even distribution of liquid out of an applicator is enhanced by flowing liquid through a row of orifices and into an impingement plate before flowing the liquid out of an outlet slot or orifices. A non-wetting or subliming powder may be included in the liquid or fluid that renders the coating porous on the substrate.

    Abstract: A process and apparatus for directing coating materials at a substrate with reduced production of mist and enhanced range of coating thickness and uniformity of coverage. A flow of coating liquid or fluid (821) is directed toward a substrate, and attenuated (826) in transit by a co-flowing impingement fluid (823). The impingement fluid is capable of attenuating liquid in the coating stream into droplets that form a fine mist (827). The mist is propelled toward the substrate (826) by the impingement fluid and deposited on the substrate. The aqueous liquid is preferably less than 100 DEG C, and directed through an outlet under a low pressure, for example, less than 12 psi (82 kPa, such that the liquid velocity is low (e.g. less than 1 meter/second). Process parameters may be varied to reduce grainy or streaky coatings, thereby assuring thorough coverage of a substrate even with very thin coatings.

    Abstract translation: 一种用于将涂料材料引导到基材上的方法和装置，其减少了雾的产生并且增加了涂层厚度的范围和覆盖的均匀性。 涂覆液体或流体（821）的流动指向基底，并且通过共流冲击流体（823）在运输过程中衰减（826）。 冲击流体能够将涂覆流中的液体减弱为形成细雾的液滴（827）。 雾通过冲击流体被推向衬底（826）并沉积在衬底上。 含水液体优选小于100℃，并在低压下引导，例如小于12psi（82kPa），使得液体速度低（例如小于1米/秒）。 可以改变参数以减少颗粒状或条纹涂层，从而即使用非常薄的涂层也能确保基材的彻底覆盖。

    Abstract: An applicator (58) directs a flow of a liquid (78) toward a substrate (60) and forms droplets that deposit uniformly on the substrate (60). The applicator (58) includes a liquid outlet that directs an elongated distribution of liquid toward the substrate (60), while an impingement fluid is propelled through an adjacent fluid impingement slot against the liquid (78). The impingement fluid changes the confluent liquid flow into fine droplets that deposit uniformly on the substrate (60). This applicator is capable of coating substrates (60) very uniformly, and producing coatings that are less streaky and grainy than spray nozzle applicators. The applicator (58) is capable of depositing liquid coatings over a wide range of application rates and depositing coatings on a wide range of substrates (60).
