Abstract: Disclosed are a 5th generation (5G) message processing method, a 5G message center, a terminal device, and a storage medium. The 5th Generation (5G) message processing method may include: determining a first node and a second node from all nodes which are to receive a 5G message, and generating a first list according to node information of the first node, wherein the first node and the second node belong to the 5G message center; sending, to the first node, a group-sending file corresponding to the 5G message; and delivering, to the second node, a notification message comprising the first list and a group-sending notification, such that the second node acquires the group-sending file from at least one first node in the first list according to the group-sending notification.

Abstract: The present disclosure discloses a method for preparing a polyurethane foam using an extract of cotton spinning black liquor, including the following steps: step (1): extracting biomass in cotton spinning black liquor by acid precipitation to obtain the extract of cotton spinning black liquor; step (2): pretreating the extract of cotton spinning black liquor, and uniformly mixing the pretreated extract of cotton spinning black liquor with a polyether polyol to obtain a mixed raw material; and step (3): preparing the polyurethane foam from the mixed raw material, dibutyltin dilaurate, distilled water, a foam stabilizer, aluminum hypophosphite and an isocyanate by one-step foaming. The present disclosure can solve the problems of high treatment cost and low utilization rate of the existing cotton spinning black liquor.

Abstract: Metal plastic forming processes and equipment that provides a flexible skew rolling mill with dual-rotatable-shafts, including a base unit, a guide unit, two rollers, two servo main-shaft systems, a roller distance adjusting mechanism, two tilt angle adjusting mechanisms, a cooling system and a numerical control system.

Abstract: The technical field of metal plastic forming processes and equipment, and provides a device and method for forming shaft part by two-roller flexible skew rolling. The device comprises two skew rollers, a guiding plate, two guiding cylinders and an axial pushing device; the skew rollers can do same-direction rotation motion, radial feeding motion and tilt angle adjustment motion; the guiding plate is arranged between the two skew rollers and is used for limiting the radial movement of a blank; the two guiding cylinders are arranged on the two sides of the two skew rollers to limit swing of the blank; and the axial pushing device is arranged at one end of the blank and is used for applying axial pushing force to the blank, and the blank is rolled into a shaft part in a space defined by the skew rollers and the guiding plate.
