The invention provides a process of producing an interconnecting multi-layered LVT tile for a modular flooring system, the process comprising the steps of: a) forming a base substrate of plastics material with at least one locating guide by injection moulding; b) coating the back of an LVT surface layer with adhesive; c) aligning the LVT surface layer to a top surface of the base substrate such that the LVT surface layer abuts the or each locating guide of the base substrate; d) press rolling the base substrate and LVT surface layer together to form an oversized blank; and e) punching out an interlock shape from the oversized blank using a punch and die tool.

A grip pack for providing a slip-resistant, water-resistant, and antibacterial surface to a piece of sporting equipment including at least three substrates printed with images. The images are printed with ultraviolet curable ink and the substrates are non-silicone. Each substrate includes a top printable layer, a middle adhesive layer, and a bottom removable layer. The top printable layer is printed with an image. The bottom removable layer is removable from each substrate printed with an image to expose the middle adhesive layer. The middle adhesive layer is configured to adhere the top printable layer to a surface of the piece of sporting equipment. Each substrate printed with an image and each image printed with ultraviolet curable ink is smoothed flat to conform to the shape of the piece of sporting equipment and provide a smooth protective layer with the slip-resistant, water-resistant, and antibacterial surface.

A method of fabricating a ceramic matrix composite material into a part, including applying a semi-permeable membrane over a stack of composite plies pre-impregnated with ceramic matrix. The semi-permeable membrane comprises a porous plastic material and may have a thickness of approximately 0.002 to 0.008 inches. The method may include compressing the semi-permeable membrane and the stack together and heating the semi-permeable membrane and the stack to cure the stack into the composite part. The semi-permeable membrane may be a porous plastic having pores large enough to allow volatile gasses to escape therethrough during curing but equal to or smaller than solid ceramic particles or clusters of the solid ceramic particles suspended in the ceramic matrix. The composite plies may contain approximately 35 percent to 45 percent of the ceramic matrix by weight relative to an overall weight of the stack of the composite plies pre-impregnated with the ceramic matrix.

Finishing system for a 3D printed object involves applying a film to an outer surface of the object in order to hide surface artifacts associated with the 3D printing process that created the object.

Provided is a surface protective sheet whereby antifouling properties are enhanced and excellent wiping properties and sliding properties are ensured, the present invention is a surface protective sheet (1) having a protective film (3) on a surface of a substrate (2). The protective film (3) is configured from a cured product of a curable composition, the curable composition includes a coating material and a curable resin. The coating material is configured from a reaction product of at least compounds A, B, C and D. Compound A is an acrylic polymer having a hydroxyl group in a side chain thereof, compound B is a diisocyanate, compound C is a polyether polyol, and compound D is a photopolymerizable compound having both a hydroxyl group and a photopolymerizable group. The content of the coating material and the curable resin in the curable composition is preferably 2 parts by mass or more and 40 parts by mass or less of the coating material and 60 parts by mass or more and 98 parts by mass or less of the curable resin when the total amount of the coating material and the curable resin is 100 parts by mass.

The invention relates to a process comprising: (a) preparing a curable epoxy-anhydride thermoset composition; and (b) applying said curable epoxy-anhydride thermoset composition in a cured-in-place pipe rehabilitation process is disclosed. The cured-in-place pipe application utilized can generally be the Inversion Installation Method, or the Pull-in Installation Method. The invention also relates to a cured-in-place pipe that is prepared by this process.

Protective coverings herein have a coated woven material with a first edge parallel with a warp direction and a second edge opposite the first edge, and have a first edge band proximate the first edge and a second edge band proximate the second edge. The coated woven material has a woven scrim made of a plurality of weft tapes and a plurality of warp tapes, but the warp tapes positioned in the first and second edge bands are high-shrinkage warp tapes and the warp tapes positioned in between the first and second edge bands have a shrinkage that is less than a shrinkage of the high-shrinkage warp tapes, and has a coating on at least one major surface of the woven scrim. The plurality of high-shrinkage warp tapes shrink upon application of heat. Methods of covering a load, such as stacked lumber, with the protective covering are also disclosed.

A kit for encapsulating a length of pipe features first and second foam sections cooperatively shaped to form a cavity with open ends in a working configuration of the foam sections for receiving the length of pipe therein. A low density foam, which is lower in density than the material of the foam sections, fills an unoccupied space in the cavity so as to provide cushioning for the length of pipe such that movement of the length of pipe within the cavity is permitted and stress on the length of pipe is reduced. The foam sections may be reinforced with reinforcing membranes carried in a main body of the respective foam section. The reinforcing membranes may act to hold the foam material of the respective section together and to prevent puncture along a full thickness of the foam sections from abrasive debris in the ground.

Disclosed is a method for preparing graphite film, comprising steps as follows: 1) winding; 2) carbonizing at a low temperature; 3) graphitizing at a high temperature; 4) unwinding and feeding, winding up the electrographite film semi-finished product and flexible graphite paper separately; 5) calendaring to press the electrographite film semi-finished product against release film or protective film; 6) winding up and packaging. The winding process comprises steps as follows: a. winding high temperature resistant elastic material around the graphite cylinder core; b. bonding macromolecular film to flexible graphite paper, and then winding around the graphite cylinder core based on step a; c. when the macromolecular film and flexible graphite paper wound in step b reach the predetermined thickness, securing with carbon cord.
