Disclosed is a method and apparatus for continuous coating with a rotational die in which coating materials flow in a radial direction. The linear speed of a substrate in need of coating is identical to the tangential speed of the surface of the rotational die so that the coating material, which flows in a radial direction of the rotational die, flows onto the substrate perpendicularly. Therefore, the ingredients of coating materials overlap one another (or stand vertically as a layer), and the vertical sequence of the coating material is ensured. This method and apparatus can be used to make organic electronic devices, organic light-emitting diodes and organic photovoltaic devices. Particularly, this method and apparatus can be used in bulk-hetero-junction of mixed coating of P-type and N-type semiconductors.

A coated glass mat comprises a glass mat substrate having non-woven glass fibers and a coating which essentially uniformly penetrates the glass mat substrate to desired fractional thickness of the coated glass mat. The coating imparts a tensile strength to the coated glass mat which on average is at least 1.33 times greater than the tensile strength of the glass mat substrate without the coating. In example embodiments, penetration of the coating into the glass mat substrate preferably extends to a depth of from twenty five percent of a thickness of the coated glass mat to seventy five percent of the thickness of the coated glass mat. Moreover, a non-coated thickness of the coated glass mat is sufficiently thick for bonding purposes with, e.g., a gypsum slurry or other core materials such as thermoplastic or thermosetting plastics. The coating has a porosity in a range of from 1.3 CFM to 5.0 CFM, e.g., the coating comprises a coating blend which provides the coated glass mat with a porosity sufficient to allow water vapor to escape from a gypsum slurry when heated. The coating is preferably a coating blend comprised of water, latex binder, inorganic pigment, and inorganic binder.

A coating device is provided which has a bar which coats a coating liquid on a strip-shaped body conveyed in a given direction, and a dam-shaped member disposed at an upstream side of the bar so as to face the bar. Also provided is a coating method which, in the coating device, supplies the coating liquid from between the dam-shaped member and the bar so as to carry out coating. A flow rate of the coating liquid passing through a gap between the strip-shaped body and the dam-shaped member is set to be 3 m/min or more. A flow rate of the coating liquid passing through a gap between the bar and the dam-shaped member is set to be 5 mm/sec or more.
摘要:
An apparatus for successive application of two coats of at least one coating medium on one side of a traveling fiber material web includes a rotating backing roll and a first rotating applicator roll having a roll surface. The first applicator roll and the backing roll define a first press nip therebetween. A first applicator assembly is positioned in association with said roll surface for applying a first coating medium to the roll surface. The first applicator assembly and the first applicator roll conjunctively define a first indirect applicator for applying the first coating medium to a first side of the fiber material web. A first drying apparatus is positioned after the first press nip relative to a direction of travel of the fiber material web. The first drying apparatus is positioned in association with the first side of the material web. A second applicator is positioned after the first drying apparatus relative to the direction of travel of the fiber material web. The second applicator is also positioned in association with the backing roll whereby the traveling fiber material web travels between the second applicator and the backing roll. The second applicator is configured for applying a second coating medium to the first side of the fiber material web.
摘要:
The process and apparatus of the present invention teaches how to treat a well-integrated woven or non-woven web of hydrophobic fibers to make selective areas hydrophyllic. It also can be used to make a web of hydrophyllic fibers selectively hydrophobic. It uses a plurality of selectively adjustable covers on an applicator roll rotating in a bath of liquid to place the liquid material on selective areas of the moving web. In a preferred embodiment the web is non-woven and the fibers are hydrophobic in nature, e.g., dry-laid or melt-blown polypropylene or polyethylene fibers or spun-bonded hydrophobic filaments. A woven web made of cotton or other hydrophyllic fibers may also be used if the end result is to create partially hydrophobic areas on a hydrophyllic web. The areas of liquid are positioned on the web only where desired so as to eliminate the excessive cost of unwanted and unnecessary coating material. If the web is hydrophobic, the liquid makes that area hydrophyllic. If the web is hydrophyllic, the liquid makes that area hydrophobic.
