The present invention relates to the field of displays and discloses a polyimide substrate, which is manufactured by reacting lignin, polyimide and a free radical initiator. Because lignin contains various active groups, for example, hydroxyl, carboxyl and aryl, etc., when it is introduced into the polymer structure of polyimide, the maximum absorption peak of the polymer can be made to redshift from less than or equal to 280 nm to less than or equal to 380 nm, so that a certain absorption and screening action may be laid on the light wave during a subsequent Laser Lift Off process, and the substrate and the liquid crystal may be prevented from being damaged during a Laser Lift Off process of the glass base substrate, thereby guaranteeing the display quality of the flexible display.

A foam filled wheel and its manufacturing method, wherein it comprises: a steel ring, connecting a power device of the car, wherein the steel ring has a filling mouth; a tire set outside around the steel ring; and filling materials, disposed between the steel ring and the tire through the filling mouth; it is characterized in that: the filling materials are foaming materials, thereby the tire will not leak, thence it is achieved that the tire can support the car steadily in case of damage.

On-line synchronous registering co-extrusion SPC floor includes a base material layer, a decorative layer, and a wear-resistant layer. The decorative layer is arranged on the base material layer and provides patterns and designs. The wear-resistant layer is arranged on the decorative layer, is a transparent layer or a semi-transparent layer, and is provided with a concave-convex surface. The patterns or designs correspond to the concave-convex surface; the base material layer is composed of an elastic layer, a strength layer, and a stable layer, and shading is pressed on the bottom layer of the stable layer. Two co-extrusion lines are used for simultaneous extrusion to achieve an ABA three-layer effect of an SPC base material layer. A calender matches a synchronous registering system, and the patterns of the decorative layer are formed in a rolling manner.

Reticular structure made of material including: a biodegradable polymeric composition in a percentage by weight greater than 90% with respect to the total weight of the material of the reticular structure and a stabilizing additive configured, in use, for reducing the degradation of the reticular structure. A process for making said reticular structure and to a use thereof.

A method of making a homogeneous mixture of polyolefin solids and carbon solids without melting the polyolefin solids during the making. The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the carbon solids for a period of time sufficient to substantially intermix the polyolefin solids and the carbon solids together while maintaining temperature of the heterogeneous mixture below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.

The present invention relates to a process for forming cellulose fibers or film from dissolved cellulose. The process comprises the steps of: dissolving cellulose in an aqueous coagulation sodium salt solution to provide a cellulose spin dope; extruding the cellulose spin dope into a coagulation bath liquid comprising an aqueous coagulation sodium salt solution to provide cellulose fibers or film; withdrawing a portion of the coagulation bath comprising coagulation sodium salt and sodium hydroxide (NaOH); cooling the withdrawn portion of the coagulation bath to precipitate solid coagulation sodium salt to recover sodium hydroxide (NaOH) substantially free from the coagulation salt; and using at least a portion of the recovered sodium hydroxide (NaOH) in dissolving the cellulose to provide the cellulose spin dope.
