A method and a device for coating a metal strip with a coating material that is still liquid at first. During the coating, the coated metal strip runs through a roller pair. One of the rollers of the roller pair can be adjusted toward the other as a correction roller in order to eliminate a possible curvature of the metal strip. Then the metal strip runs through a blow-off apparatus for blowing off surplus coating. In order to prevent an uneven thickness distribution of the coating on the metal strip even when the correction roller of the roller pair has been adjusted, the actual position of the metal strip is controlled to a specified setpoint center position in the slot of the blow-off apparatus by an appropriate movement of the blow-off apparatus.

A continuous ceramic matrix composite strip is produced by passing a dry ceramic fiber strip through a ceramic slurry bath. Impregnation wheels within the bath guide the fiber strip through the bath and force the ceramic slurry into the fiber strip, thereby impregnating the strip. The impregnation wheels stir the ceramic slurry to maintain a homogeneous mixture. Air knives remove excess slurry from the strip. Thickness and width controls squeeze the impregnated strip to desired thickness and width dimensions.

A system for the functionalization of polyolefin fiber includes a reactor chamber, a fiber pulley system, and a precursor sprinkler system. The reactor chamber defines an interior reactor space and a plurality of fiber inlet/outlet pairs positioned at opposite ends of respective fiber processing axes. The fiber pulley system is arranged to direct polyolefin fiber through the plurality of fiber inlet/outlet pairs, along a fiber processing path comprising the respective fiber processing axes. The precursor sprinkler system is operable to aerosolize a precursor solution and contact the aerosolized precursor solution with the polyolefin fiber. A method for functionalizing polyolefin fiber includes aerosolizing the precursor solution to form an aerosolized precursor solution, passing polyolefin fiber along the fiber pulley system into the reactor chamber, contacting the polyolefin fiber with the aerosolized precursor solution, and passing functionalized polyolefin fiber out of the interior reactor space of the reactor chamber.

The present invention relates to a method for manufacturing an aerogel sheet and comprises: a step (a) of impregnating an acid solution into a fiber sheet to clean the fiber sheet by using the acid solution and impregnating a binder solution into the fiber sheet that is cleaned by using the acid solution to manufacture a pre-processed fiber sheet; a step (b) of impregnating a silica precursor into the pre-processed fiber sheet; and a step (c) of a gelling catalyst into the fiber sheet into which the silica precursor is impregnated to gelate the silica precursor.

A die with alignment mechanism includes a die including a through-hole through which a traveling wire travels, a bearing member for rotationally moving the die in a circumferential direction of the traveling wire, and a movable member that moves the die so that a central axis of the through-hole is aligned with a travel direction of the traveling wire without inhibiting the rotational movement of the die produced by the bearing member when the travel direction changes in a direction orthogonal to the travel direction.

In the flux applying device, a control portion controls conveying rollers or the like so that thickness of flux applied to solder is controlled. The winding roller rotates so that the solder is conveyed at the conveying speed. The drawing-out roller applies any load (back tension) to the solder backward along the conveying direction of the solder when drawing out the solder. The solder is conveyed at the predetermined speed and dipped into the flux tank containing flux. The solder is pulled up from the flux tank at the conveying speed vertically. By pulling up the solder from the flux tank at the constant conveying speed vertically, the interfacial tension acts on the solder 9a and the flux, so that the flux having a uniform thickness according to the conveying speed remains on the surface and back surface of the solder.

An automatic processing device of a carbon fiber tube includes a polishing device, a washing device, a first drying device, a printing device, a painting device and a second drying device centrally disposed along an identical axis in sequence to form an automatic production line. The polishing device includes feeding mechanisms disposed on two sides of a frame respectively and a positioning-polishing mechanism disposed between the feeding mechanisms.

A nanosynthesis apparatus includes an outer tube and an inner tube with surfaces that oppose each other across a gap as part of a reaction chamber. A deposition fluid flows along the reaction chamber to grow nanostructures such as graphene or carbon nanotubes on a substrate in the reaction chamber. The reaction chamber may have an annular cross-section, and the growth substrate may wrap around the inner tube in a helical manner. This configuration can allow a flexible film substrate to travel through the reaction chamber along a path that is significantly longer than the length of the reaction chamber while maintaining a uniform gap between the substrate and the reaction chamber wall, which can facilitate a uniform temperature distribution and fluid composition across the width of the substrate.

A method of applying a coating liquid to an optical fiber is described. An optical fiber is drawn through a guide die into a pressurized coating chamber and through the pressurized coating chamber to a sizing die. The pressurized coating chamber contains a coating liquid. The method includes directing coating liquid in a direction transverse to the processing pathway of the optical fiber in the pressurized coating chamber. The transverse flow of coating liquid counteracts detrimental effects associated with gyres that form in the pressurized coating chamber during the draw process. Benefits of the transverse flow include removal of bubbles, reduction in the temperature of the gyre, improved wetting, homogenization of the properties of the coating liquid in the pressurized coating chamber, and stabilization of the meniscus.
