The composite wax is prepared by mixing 42-79% of polyolefin wax, 20-50% of polyolefin, 0.1-3% of ethylene bis(stearamide), 0.5-5% of an inorganic filler and 0.01-0.2% of pigment powder. The composite wax prepared in the invention has the advantages of high melting point, good cutting surface, no electrostatic adsorption phenomenon, moderate hardness, and provision of an excellent processing precision for CAM/CAD.

The invention discloses a photoelectric hybrid driven foot type electrostatic adsorption wall-climbing robot, belongs to the field of wall-climbing robots, and aims to solve problems that the load capacity of an existing electrostatic adsorption type wall-climbing robot is weakened due to the fact that the weight of the existing electrostatic adsorption type wall-climbing robot is large and when crawler type electrostatic adsorption wall-climbing robot makes turn, the electrode surface of the crawler type electrostatic adsorption wall-climbing robot rubs against wall surface, the electrostaticadsorption force is destroyed, and robot falls onto wall surface. The wall-climbing robot comprises two foot-type structures and a connecting assembly, each foot-type structure comprises a foot plate; a layer of flexible electrode is attached to the lower surface of the foot plate, the flexible electrode is connected with a high-voltage module attached to the connecting assembly through a wire, afirst steering engine is further installed on the upper surface of the foot plate, and the end of an output shaft in the first steering engine is fixedly connected with one end of the connecting assembly. The wall-climbing robot is mainly used for attaching and climbing on a vertical wall surface, and can carry tools to complete certain operation tasks.

The invention provides a water color image recognition chamber suspension type automatic cleaning device, and relates to the technical field of environment monitoring. The water color image recognition chamber suspension type automatic cleaning device comprises a cleaning cabin and a ground platform, wherein the cleaning cabin is divided into a first cleaning hemisphere and a second cleaning hemisphere along a vertical center line; an electrostatic device and an angle regulating device are arranged inside the cleaning cabin; a recognition lens is arranged inside the cleaning cabin; a brushing device and a cleaning device are respectively arranged outside the cleaning cabin; a winding device is arranged on the top surface of the cleaning cabin; one end, far away from the cleaning cabin, of the winding device is fixed with the top surface of the ground platform; a cleaning box is fixedly arranged on the top surface of the ground platform; a cleaning pipe is arranged at one side of the cleaning box in a penetrating way; the bottom end of the cleaning pipe penetrates through the top surface of the cleaning device; a switch valve is arranged on the surface of the cleaning pipe, so that the cleaning cabin is more thoroughly cleaned; the water color recognition shooting definition is improved; the pollution of electrostatic adsorption dust on the recognition lens is prevented, so that the shooting recognition is clearer; through the angle regulation of the recognition lens, the shooting range of the recognition lens is wider; and the multi-direction analysis on the water color is convenient.

The invention relates to negative oxygen ion environment-friendly plastic powder with air purifying and bacteria inhibiting functions and an environment-friendly antibacterial filter screen, and belongs to the technical field of environment-friendly materials. The negative oxygen ion environment-friendly plastic powder with the air purifying and bacteria inhibiting functions comprises plastic powder and auxiliary additives, and the weight part of the auxiliary additives is less than or equal to 10%; and the auxiliary additives comprise nanoscale titanium dioxide powder, hexacyclic stone powder, a lubricant and calcium carbide powder. The environment-friendly antibacterial filter screen adopts the negative oxygen ion environment-friendly plastic powder with the air purifying and bacteria inhibiting functions, the environment-friendly molding powder adheres to the filter screen through an electrostatic adhesion method, then the filter screen is placed in a high-temperature baking oven tobe baked for 15-20 min at the temperature of 150-200 DEG C, and finally the filter screen is taken out to be cooled. According to the environment-friendly plastic powder disclosed by the invention, the titanium dioxide powder, the hexacyclic stone powder, the lubricant and the calcium carbide powder are added as the auxiliary additives, the hexacyclic stone powder can generate negative oxygen ions, and the negative oxygen ions can be generated after the environment-friendly plastic powder is sprayed to the surface of a material, so that the effects of bacteria killing and inhibiting are achieved.

The invention relates to a textile fiber product containing rare earth elements. The textile fiber product contains a textile fiber product body and rare earth elements. The rare earth elements are artificial promethium and neodymium-cerium alloy, the rare earth elements and the textile fiber product are combined by electrostatic adsorption, electrostatic adsorption has small damage to the textile fiber product, adding of the rare earth elements does not change the color and softness, the ferromagnetism of the rays and alloy in the rare earth elements also plays a certain role in health in addition to industrial and living fields. The textile fiber product provided by the invention utilizes the ferromagnetism, heat sources, light and other characteristics generated by rays and alloy in active elements of rare earth, realizes the functions of rare earth in the textile fiber product, and achieves the purposes of life cultivation and health preservation.

The invention discloses a preparation method of an air filtering material. The method comprises the following steps: pretreatment of fiber, preparation of hydrophobic fiber, preparation of modified attapulgite, and preparation and spraying of spraying materials. The method has the advantages that the surface of polyester fiber is modified through an alkaline solution and acrylic ester, the structure of the polyester fiber is destroyed, the cohesive force among the polyester fiber is reduced, and the surface roughness and specific surface area of the polyester fiber are improved, so that the adsorption capacity of the polyester fiber is enhanced, meanwhile the polyester fiber has excellent hydrophobic capacity, the polyester fiber is prevented from absorbing moisture and sticking together,and the filtering capacity of modified polyester fiber is enhanced; the method further combines activated carbon and attapulgite, the characteristic that the adsorption property of activated carbon ishigher than that of attapulgite is utilized, and the situation that a large quantity of activated carbon particles are in contact with one another to form a conducting loop to reduce the electrostatic adsorption capacity of the polyester fiber is further avoided, so that the adsorption capacity to particulate pollutant and peculiar smell in the air by the polyester fiber is improved.
