The present invention belongs to a special cone-shaped double-screw extruding machine for a wood-plastic composite material of the plastic processing machine, including a power source, a reduction gear box, a screw-machine barrel accessory, a machine frame and a feeding bucket. The power source is connected with a screw inside the screw-machine barrel accessory through the reduction gear box. The feeding bucket communicates with a machine barrel inside the screw-machine barrel accessory. The screw is installed inside the machine barrel. Cooling and temperature-reducing device are installed at the lower part of a feeding opening of the machine barrel and at a closely adjacent section to make the two sections as cooling sections, the sections after which are provided with heating devices which make the rest sections as the heating sections. Only one vent is arranged at the machine barrel. The screw, which is installed inside the machine barrel, is the cone-shaped screw and is provided with a mixing section, and the same time the length-diameter ratio of the machine barrel and the screw is more than 30. Before the vent, the present invention can convey, compress, heat and plastify the wood-plastic composite material under the quite low temperature; after being completely plastified, the plastic can complete enwrap the heated wooden powder before the vent and mix with the wooden powder uniformly; a double-screw vacuum exhausting and flash-preventing device which continuously rotates downwards can exhaust as well as never flash.

The invention discloses a high-strength and high-conductivity CuCrZrMg series copper alloy wire. The high-strength and high-conductivity CuCrZrMg series copper alloy wire comprises the following components in percentage by mass: 1.5-15.0% of Cr, 0.1-2.5% of Zr, 0.05-1.0% of Mg and the balance being copper and inevitable impurities. In addition, the invention also discloses a preparation method ofthe high-strength and high-conductivity CuCrZrMg series copper alloy wire. The preparation method comprises the following steps: step one. carrying out fusion casting to obtain an ingot casting; steptwo. carrying out surface treatment and homogenization treatment on the ingot casting; step three. carrying out cold forging to obtain a bar, and then carrying out cold rotary forging to obtain a wire bar; and step four. drawing the wire bar to obtain the wire, and carrying out ageing treatment on the wire. The high-strength and high-conductivity CuCrZrMg series copper alloy wire has the beneficial effects that the wire is reasonable in design of the alloy components, high in alloying degree, appropriate in production cost, controllable in technology and environmentally-friendly and has highalloy strength and high electrical conductivity; and the high tensile strength and the high electrical conductivity can meet the requirements of high current connectors, electric power, machinery andelectronics and the like on high-strength and high-conductivity materials.

Disclosed is a writing instrument which enables visual identification of a wide range of writing directions through a visual identification section of a pen nib and ensures consistent writing to the last touch of writing. To this end, the pen nib (40) includes a porous structure (45) serving as a writing section, and a holding structure (55) which holds the porous structure (45) and has at least one ink guide section (50) for supplying ink to the writing section. The writing instrument has a relay porous structure (30) for supplying the ink contained in a writing instrument body (10) to the ink guide section (50) provided in the holding structure (55), and allows the holding structure (55) to serve as the visual identification section for visually identifying the direction of writing. The area ratio of the visual identification section to the pen nib (40) that is protruded from the end of the writing instrument body is adapted to be 40% or greater.
