Abstract: A double-sided pressure-sensitive adhesive tape having excellent impact resistance, excellent reworkability, and excellent alcohol resistance. The double-sided pressure-sensitive adhesive tape includes: a base material layer; and pressure-sensitive adhesive layers arranged on both surface sides of the base material layer, wherein the pressure-sensitive adhesive layers are each formed from a pressure-sensitive adhesive composition, wherein the pressure-sensitive adhesive composition contains at least one kind selected from the group consisting of a monomer component (m) and a polymer component (P) obtained by polymerizing the monomer component (m), wherein the monomer component (m) contains 50 wt % or more of butyl (meth)acrylate, wherein a ratio of a thickness of the base material layer to a total thickness of the double-sided pressure-sensitive adhesive tape is less than 35%, and wherein the double-sided pressure-sensitive adhesive tape has a force, which is generated at 100% strain at 23° C.
Abstract: A universal membrane is configured to be installed between a subfloor and floor tiles to allow movement of the floor tiles relative to the subfloor. The universal membrane includes a base layer, a plurality of studs projecting from the base layer, and a plurality of sidewalls projecting from the base layer and disposed between adjacent ones of the plurality of studs. Each sidewall of the plurality of sidewalls forming a perimeter of a pocket. The base layer forms a bottom wall of the pocket.

Abstract: An impact-absorbing assembly includes a covering layer being one or more of artificial turf, rubber mats, polymer mats, short pile carpeting, particulate infill, wood chips, and ground rubber chips. Also included is a layer of underlayment panels positioned beneath the covering layer. The panels have a panel section with a plurality of drain holes formed therethrough. A top surface of the panels is configured to support the covering layer. A bottom surface of the panels has a plurality of bottom projections that cooperate to define bottom channels suitable to permit water flow across the bottom surface, the bottom channels being in fluid communication with the panel drain holes. The bottom projections define a first spring rate characteristic that is part of a first stage and a second spring rate characteristic is part of a second stage, the first stage having a smaller volume of material than the second stage.
Abstract: Technical fields of building external wall decoration and material manufacturing, providing a mildewproof and antirot high-strength cement particle board and a preparation method thereof. The preparation method includes: (1) sequentially carbonizing and water-washing a shaving, and mixing the obtained carbonized shaving with a cement gelling agent, a curing agent aqueous solution and water to obtain a mixture; (2) molding the mixture to obtain a pre-molded material; and (3) sequentially curing and drying the pre-molded material to obtain the mildewproof and antirot high-strength cement particle board. Compared to ordinary cement particle board, which is not subjected to carbonization treatment and water-washing, the cement particle board of the present invention can effectively avoid mildew and rot, and can significantly improve the mechanical strength and durability thereof, helping to extend the service life of the cement particle board.

Abstract: A transmission for a vehicle includes a knob configured to be rotated to select one of a plurality of shift stages, a driving unit for controlling rotation of the knob, and a shift controller for applying an electrical current to generate a torque in the driving unit. Further, the driving unit includes a magnetic field generator, a magnetization unit including a plurality of magnetic bodies arranged at regular intervals along a circumference of the magnetic field generator, and a magnet unit including at least one pair of magnetic poles arranged along a circumference of the magnetization unit. In particular, the magnetization unit or the magnet unit is coupled with the knob and rotates integrally with the knob. Depending on an intensity of a magnetic field generated by the magnetic field generator, the driving unit allows or prevents the rotation of the knob.
