Theelectrolyte paper is made of Manila hemp and soaked with the electrolyte solution. The mouth of the aluminum casing is sealed with rubber ring of rubber mixture. The aluminum electrolytic capacitor has electrolyte solution well adsorbed onto the anode aluminum foil and the cathode aluminum foil, no corrosion to leads, high sealing performance and other advantages.

The invention provides an aluminum electrolytic wound capacitor-fixing pressure-sensitive adhesive tape and an aluminum electrolytic capacitor using the same. The tape can be used for aluminum electrolytic capacitors without causing tape breakage in the tape wrapping process, without causing a reduction in taping workability and with preventing the problem of an unnecessary increase in the size of the wound capacitor. The aluminum electrolytic wound capacitor element-fixing tape includes a pressure-sensitive adhesive layer provided on one side of the supporting base material, wherein the supporting base material includes at least one layer of Manila hemp paper, Kraft paper, synthetic fiber paper, or mixed paper made of two or more thereof, the supporting base material has a density of more than 0.9 g / cm 3, and the supporting base material (1) has a thickness of 15 to 50 [mu]m.

The invention discloses a water and oil resistant oil filter paper, which is characterized by being prepared from the following raw materials by weight part: 50-56 of bagasse pulp, 46-49 of Manila hemp pulp, 2-4 of zircon powder, 2-3 of feldspar powder, 1-2 of magnet powder, 0.5-0.9 of n-dodecyltrimethoxysilane, 0.5-0.7 of sodium alginate, 0.2-0.3 of polygalactose mannose, 6-8 of a polyvinyl acetate emulsion, 2-3 of butyl acrylate, 0.5-0.7 of benzalkonium bromide, 0.4-0.6 of polyvinyl ether, and 1-2 of an assistant. Through organic combination of a ceramic material with filter paper, the filter paper prepared by the invention is solid and durable, and has good filtration effect and adsorption effect. Added with the assistant, the oil filter paper is safe and environment friendly, and has good water resistance and oil resistance. The added zircon powder and magnet powder can well filter out the metal abrasive dust generated by an engine in the combustion process and mixed into engine oil, carbon granules, colloid generated by the engine oil, and other impurities, thus reducing exhaust gas emission.

The invention discloses a roadbed paving structure for highway extension and a construction method of the roadbed paving structure for the highway extension. The roadbed paving structure for the highway extension comprises a cushion layer, a lower base layer, an upper base layer and a surface layer, wherein a fixing frame is arranged between an intermediate layer and a gravel layer to increase thebonding strength of the upper base layer and the lower base layer so as to prevent hierarchical separation, furthermore, the cushion layer is located at the bottom layer, thereby being capable of enhancing the structure stability and dispersing the roadbed stress to prevent sinking, a traction part is arranged between the surface layer and the upper base layer to increase the bonding strength between the layers so as to prevent the surface layer from being separated, wherein one or more of steel wires, manila hemp fibers, carbon fibers and polytetrafluoroethylene fibers are arranged inside the traction part, therefore the materials are combined to make the traction part tough and corrosion-resistant, and then the traction part is not easily corroded by cement, and in addition, the problemof weak adhesive force of the polytetrafluoroethylene fibers and the cement or asphalt is solved. A connecting part is further arranged and comprises a plurality of dovetail grooves and clamping blocks adapted to the dovetail grooves, the dovetail grooves and the clamping blocks are respectively arranged on a joint surface of an old road and the roadbed structure to prevent a newly widened roadbed from sinking or cracking or separating relative to the old road.
