The invention relates to a method to test the constitution of hydrogenation tail oil paraffin group by near infrared optical spectrum. It builds up models of paraffin, alkane, and isoalkane by alkene cracking device, and aromatics reformer and oil refining hydrogenation unit. And the content of paraffin, alkane, and isoalkane would be calculated by using the models. It has the advantages of convenient, rapid and accurate.

The invention discloses a sucker rod blowout-preventing, self-sealing, paraffin scraping and flow guiding device. A sucker rod penetrates through the center of a shell, and a paraffin scraping deviceis mounted in the shell and arranged on the sucker rod in a sleeving mode. Circular flow guiding plates are arranged on the two sides of the paraffin scraping device, at least one flow guiding pipe isarranged on the side wall of the shell, and the outer ends of the flow guiding plates are connected with the flow guiding pipes. Filtering plates are arranged above the flow guiding plate, casing pipes are arranged in the centers of the filtering plates and mounted at the upper end of the paraffin scraping device, and the two ends of the flow guiding pates are movably connected with the side wallof the shell, and steel wire ropes are arranged at the edges of the flow guiding plates and penetrate through an upper cover plate. According to the sucker rod blowout-preventing, self-sealing, paraffin scraping and flow guiding device, the flow guiding plates are arranged at the edge of the existing paraffin scraping device, and the filtering plates are fixed to the paraffin scraping device, sothat when the rocker rod moves vertically, oil paraffin scraped by the paraffin scraping device is stacked on the filtering plates and falls to the flow guiding plates from screening holes, and impurities remain on the filtering plates; and the flow guiding plates are slopes, so that the oil paraffin flows into flow guiding grooves along the slopes and further is flatly discharged from the flow guiding pipes.

The invention belongs to the field of fine chemical industry, and more particularly, relates to an electric-ignition match and a preparation method thereof. Environment-friendly, pollution-free raw materials like paraffin oil, alcohol, thickener, sawdust powder, water and adhesive are used to prepare match heads, and the match heads are attached to match sticks, so as to prepare electric-ignitionmatches. Traditional matches generate pungent, harmful oxide gases of phosphors and sulfur when being ignited, thereby giving out a pungent smell. The electric-ignition match provided by the inventiondoes not generate harmful gases harmful to environment and body health when being ignited. The electric-ignition match can be ignited by a special electric igniter for matches or a common electric stove or naked fire, thereby having advantages of environmental protection, pollution free, low price and the like.

The invention relates to the technical field of oil extraction equipment, in particular to a complete drive control device set for an oil-submersible screw pump. The complete drive control device setcomprises a control module, an oil extraction mechanism module and a downhole detection module, wherein the oil extraction mechanism module comprises the oil-submersible screw pump, an oil-submersiblepermanent magnet motor and a composite oil pipe; the downhole detection module comprises a flow sensor, a temperature sensor and a pressure sensor; the control module comprises a high-precision vector frequency converter, a detection signal feedback device and a real-time monitoring control unit; the detection signal feedback device receives downhole first oil temperature, downhole second oil temperature and flow monitoring signals and transmits the downhole first oil temperature, downhole second oil temperature and flow monitoring signals to the real-time monitoring control unit; and the high-precision vector frequency converter carries out vector control on the oil-submersible motor according to the working condition and combined with the magnitude of output currents of the high-precision vector frequency converter. The complete drive control device set for the oil-submersible screw pump solves the problem that power cables in a traditional oil extraction system are easily abraded and corroded. Meanwhile, the problem of oil paraffin deposit at the low temperature is solved, faults are effectively reduced, and an oil well is maintained.

A film preparation method based on an oil content feedback process, comprising mixing and heating polyethylene, paraffin oil, silica nanoparticles, and 4,4'-thiobis(6-tert-butyl-m-cresol) in batches, and Extrusion molding, after transverse stretching and longitudinal stretching, and then two-dimensional stretching. After stretching, the film is sent to the oil content analysis device, and the oil removal device is optimized and controlled according to the distribution of oil stains on the oil absorbing material, so as to finally obtain a lithium battery separator with low oil content.
