A system for manufacturing a thermoplastic prepreg includes a double belt mechanism that is configured to compress a fiber mat, web, or mesh that is passed through the double belt mechanism, a resin applicator that is configured to apply monomers or oligomers to the fiber mat, web, or mesh, and a curing oven that is configured to effect polymerization of the monomers or oligomers and thereby form the thermoplastic polymer as the fiber mat, web, or mesh is moved through the curing oven. The double belt mechanism compresses the fiber mat, web, or mesh and the applied monomers or oligomers as the fiber mat, web, or mesh is passed through the curing oven so that the monomers or oligomers fully saturate the fiber mat, web, or mesh. Upon polymerization of the monomers or oligomers, the fiber mat, web, or mesh is fully impregnated with the thermoplastic polymer.

Gypsum panels and methods for their manufacture are provided herein. The gypsum panels include a gypsum core having a first surface and a second opposed surface and a first fiberglass mat associated with the first surface of the gypsum core, such that gypsum from the gypsum core penetrates at least a portion of the first fiberglass mat.

Forming a two-dimensional polymeric sheet includes translating a portion of a flexible substrate through a first liquid precursor to coat the portion of the flexible substrate with the first liquid precursor, thereby yielding a precursor-coated portion of the flexible substrate. The precursor-coated portion of the flexible substrate is translated through an interface between the first liquid precursor and a second liquid precursor, thereby reacting the first liquid precursor on the precursor-coated portion of the flexible substrate with the second liquid precursor to yield a polymer-coated portion of the flexible substrate.

A method for manufacturing of a multilayer PVC semi-finished product, in particular a multilayer PVC synthetic leather or a multilayer PVC foam sheet, the method comprising the steps of:

a. Coating a coated or uncoated carrier web with a PVC plastisol, whereby a carrier web coated with an ungelled plastisol layer is obtained; thereafter
b. Gelling the ungelled plastisol layer, whereby a carrier web coated with a gelled plastisol layer is obtained; and thereafter
c. Cooling the carrier web coated with the gelled plastisol layer; characterized in that the coating comprises coating the carrier web with at least two PVC plastisols one above the other, simultaneously or in immediate succession. A corresponding apparatus is further described.

A processing method of a base material sheet includes winding out the base material sheet wound up by a first core and a first porous sheet wound up by a second core, winding up by a third core the base material sheet and the first porous sheet to be overlapped with each other, and processing the base material sheet by a first processing liquid held in the first porous sheet; and winding out the base material sheet and the first porous sheet overlappingly wound up by the third core, winding up the first porous sheet by the second core, and winding up the base material sheet by the first core.

A coiled metal substrate with a faux galvanized surface appearance. The faux galvanized surface of the substrate including a spangle print pattern of polyvinylidene fluoride (PFDV) flexographically applied to the metal substrate. Atop the PFDV print pattern is semi-transparent coating of fluoroethylene vinyl ether (FEVE) flexographically applied atop the spangle print pattern of PFDV.

According to one embodiment, a coating apparatus includes a coating bar configured to face a member to be coated, and a plurality of nozzles configured to supply a liquid toward the coating bar. A number of the nozzles is 3 or more. An arithmetic mean roughness Ra of at least a part of a surface of the coating bar is not less than 0.5 μm and not more than 10 μm.

A method for forming a resultant material. The method can include obtaining a base material including a fibrous material with a plurality of fiber portions extending from a face of the base material. The method further can include treating at least the face of the base material, the treating at least the face including applying heat along at least a portion of the face with a treatment unit to at least partially remove the plurality of fiber portions extending from the face.

The present invention relates to a surface treatment composition comprising, on the basis of 100 wt % of the solid part of the composition, 20-40 wt % of a water-soluble polyurethane resin, 40-60 wt % of a silane-based sol-gel resin in which three types of silane compounds are cross-linked, 5-15 wt % of a curing agent, 0.5-1.5 wt % of a corrosion inhibitor, 0.1-1.0 wt % of a molybdenum-based compound, 1.0-3.0 wt % of a silane coupling agent; 1.0-2.0 wt % of an organometallic complex, 1.0-2.0 wt % of an acid scavenger, 0.1-1.0 wt % of an aluminum-based compound, and 1.0-2.0 wt % of a lubricant. A ternary hot-dip galvannealed steel sheet treated with a chromium-free surface treatment coating agent, according to an exemplary embodiment in the present invention, has excellent resistance to blackening, alkali and corrosion, and provides excellent effects without concern for problems, in chromium treatment, of additional equipment installation, an increase in manufacturing costs and environmental pollution.

A method for producing secondary battery electrodes includes a step of preparing a moisture powder formed of aggregated particles that contain a plurality of electrode active material particles, a binder resin, and solvent, wherein the solid phase, liquid phase, and gas phase in at least 50 number % or more of the aggregated particles in the moisture powder form a pendular state or a funicular state; a step of forming a coating film composed of the moisture powder on an electrode current collector, while the gas phase remains present; a step of forming a depression in the coating film by carrying out, using a die having an elevation of prescribed height, depression/elevation transfer into the coating film; and a step of carrying out depression/elevation transfer, using a die having an elevation higher than the elevation of prescribed height, by pressing the higher elevation into the depression that has been formed.
