摘要： A compact steel cord is provided. The cord includes a core-filament I steel wire with a diameter of d0, and four middle-layer M steel wires with a diameter of d1 and eight outer-layer O steel wires with a diameter of d2 that are twisted around the core-filament I steel wire in the same lay direction and the same lay length. Gaps L are reserved between the outer-layer O steel wires, an average width of the gaps L is not smaller than 0.02 mm, and the total size of the gaps L is larger than d0 and smaller than d1. The steel cord of a stable structure can be obtained by controlling the proportion of the sizes of all layers of monofilaments, the rubber coating performance of a tire cord can also be improved, the corrosion resistance, fatigue resistance, impact resistance and adhesion retention of a tire are improved.

摘要： Disclosed is a post-plating treatment method for a one-step brass-electroplated steel wire, comprising the following steps: electroplating the surface of the steel wire with a brass alloy; immediately washing the electroplated steel wire with cold water, removing residues from the surface of the steel wire, and blow-drying the steel wire with cold air; immersing the blow-dried steel wire in a water-based coating solution; and taking the immersed steel wire out, blow-drying the steel wire with natural air, and taking the steel wire up. The water-based coating solution comprises a polyoxyethylene organic salt, sodium hypophosphite and the balance of pure water, the polyoxyethylene organic salt comprising a salt of alkyl polyoxyethylene ether phosphate and polyoxyethylene alkylamine.

摘要： Disclosed are a cable bead and a tire. The cable bead includes a core wire located at the middle position of the bead and at least one layer of outer winding wires wound around the core wire, each layer of outer winding wires being evenly wounded along the circumferential direction of the core wire, where the cross section of the outer winding wires is a flat surface having a major axis and a minor axis; the major axis is perpendicular to the radial direction of the cross section of the bead, and the minor axis is parallel to the radial direction of the cross section of the bead; the outer winding wires are in surface contact with the core wire; and when there are at least two layers of outer winding wires, a line contact is formed between the layers of outer winding wires.
