Electrodeless illuminating lamp

ActiveCN102243982BSimple structureImprove lighting effectsGas discharge lamp detailsMagnetic polesEngineering

An electrodeless illuminating lamp, which belongs to the illuminating lamp technology field, is disclosed. The electrodeless illuminating lamp comprises: an electric control cabinet, a pedestal, a support, a luminous tube, a coupler and a cooling system. The support is placed on the pedestal. The tube is installed on the pedestal in the support. The coupler is arranged in the luminous tube. The cooling system is used to cool the coupler. The coupler is respectively connected with the electric control cabinet and the cooling system. The coupler comprises: an inner water pipe, an external water pipe, a coil, multi-group magnets and a magnetic shield. The magnets are sleeved on the external water pipe, wherein the magnetic shield is arranged between the magnets. The coil is wound around the magnets. Coil winding directions of two adjacent magnets are opposite and magnetic poles of opposite ends of the adjacent magnets are same. Two ends of the coil form an anode and a cathode which are respectively connected with the electric control cabinet. The inner water pipe is arranged in the external water pipe, extends out of the external water pipe and forms seal connection with the end of the external water pipe. The inner water pipe is connected with a water pump of the cooling system and a water outlet nozzle is arranged on the external water pipe. In the invention, arbitrary multi-group magnets are adopted to form different models of the electrodeless illuminating lamps. A large or an ultra-large illuminating lamp can be made.

A process for preparing microporous tubes by semi-melt continuous extrusion of polymer powder

ActiveCN103448228BIncrease productivityGood for healthMolten statePolymer science

The invention relates to a process for preparing microporous tubes by semi-melt continuous extrusion of polymer powder, which is characterized in that it includes the following steps: (1) adding solid powder materials into a screw extrusion device through a hopper; (2) entering The barrel of the screw extrusion device is heated, and at the same time, the material is initially compacted by the screw, and the material becomes a semi-molten state; (3) The material enters the machine head and is further compacted; (4) The material enters the die of the screw extrusion device The mold cavity is formed into a tube shape, and the inner and outer diameters are determined under the action of the vacuum cooling calibrating sleeve, and the preliminary cooling is performed; (5) The microporous tube is cut by a cutting device. The technology of the invention is to carry out continuous extrusion molding when the polymer powder is in a semi-molten state. While realizing the continuous production of the microporous tube, the produced product does not need post-processing, thereby greatly improving the production efficiency. Because the process of the invention does not use solvent, it is beneficial to environmental protection and the health of operators.
