Abstract: Disclosed is a continuous preparation method of cellulose fibers, in which a forming tension of 0.1 to 1.9 cN/dtex is applied to a fine solution stream obtained by extrusion through a spinneret plate and air gap cooling, then the fine solution stream is fed into a coagulating bath at a speed of 80 to 1000 m/min, a traction tension of 0.075 to 1.5 cN/dtex is continued to be applied to washed fibers in a water washing system behind the coagulating bath, and finally, the washed fibers are fed into a post-treatment system for continuous and efficient spinning of finished fibers at a speed of 80 to 1000 m/min.

Abstract: The present application relates to a circuit breaker comprising a cut-off mechanism configured to cut off a conductor extending through the circuit breaker. The cut-off mechanism includes a primary cut-off mechanism and a secondary cut-off mechanism, and the cut-off mechanism comprises a primary operation phase and a secondary operation phase. In the primary operation phase, the primary cut-off mechanism slides along the secondary cut-off mechanism to execute primary cutting operations, and in the secondary operation phase, the primary cut-off mechanism drives the secondary cut-off mechanism to execute secondary cutting operations.

Abstract: The present application discloses a circuit breaker comprising: a housing defining an operating chamber and an arc extinguishing chamber; a severing mechanism provided in the operating chamber and comprising a punch, the severing mechanism being configured to sever via the punch a conductor extending through the housing between the operating chamber and the arc extinguishing chamber; an arc extinguishing medium in the form of a wire mesh and filled within the arc extinguishing chamber; and a gas flow guiding mechanism disposed around the arc extinguishing medium and configured to guide the gas from the punch of the severing mechanism through the arc extinguishing medium when the conductor extending through the housing is severed by the severing mechanism.

Abstract: The present disclosure discloses a method for preparing cellulose fiber. The method includes the following steps: 1) mixing cellulose pulp with NMMO aqueous solution of a mass concentration of 60%-85%, preferably 70% to 76%, to obtain a uniform mixture; 2) subjecting the obtained uniform mixture to dewatering for swelling, dissolution, and deaerating to obtain a cellulose spinning stock solution; 3) the cellulose spinning stock solution entering into a spinning machine after being filtered and heat exchange, and entering into a coagulation system after carrying out extruding by a spinneret-pack and cooling by air, and then coagulating in a NMMO coagulating bath of a mass concentration of 50% to 72% to obtain nascent fiber; and 4) subjecting the nascent fiber to rinsing to obtain a fiber filament bundle, and then, performing subsequent-section treatment to obtain cellulose fiber.

Abstract: A method of forming a film pattern with micro-pattern and a method of manufacturing a thin film transistor liquid crystal display (TFT-LCD) array substrate are provided. The method of manufacturing the film pattern with micro-pattern comprises: depositing a thin film on a substrate; jetting or dropping etchant on the thin film with a predetermined etching pattern by an inkjet print device; etching the thin film by the etchant; and cleaning the thin film to form a film pattern on the substrate.
