Abstract

The invention discloses a base wire of a diamond wire, and a preparation method thereof. The preparation method for the base wire of the diamond wire comprises the following steps: 1) immersing a drawn-state pearlite steel wire into a molten pure nickel plating solution, and carrying out sorbitizing heat treatment and nickel plating layer hot-dipping to obtain a semi-finished base wire product ofthe diamond wire; and 2) carrying out wet-type drawing on the semi-finished base wire product of the diamond wire to obtain the base wire of the diamond wire, wherein the base wire of the diamond wirecomprises a steel wire core wire and a nickel layer, and the outer layer of the steel wire core wire is provided with the nickel layer in a wrapping manner. The base wire of the diamond wire, and thepreparation method thereof have the following advantages: the drawn-state pearlite steel wire is immersed into the molten nickel, the sorbitizing heat treatment and the nickel plating layer hot-dipping are carried out, and then the wet-type drawing is directly carried out to obtain the base wire of the diamond wire; the nickel layer and the steel wire in the base wire of the diamond wire, which is prepared by the method, are high in binding force, and chemical nickel plating is not carried out on an existing base wire steel wire electroplated with brass any more; and two electroplating processes can be omitted, so that the pollution of waste solution and waste residue to environment is reduced.

Description

technical field [0001] The invention relates to the field of diamond wire busbars, in particular to a diamond wire busbar and a preparation method thereof. Background technique [0002] With the development of the economy and society and the improvement of people's awareness of environmental issues, the solar photovoltaic industry has gradually become one of the leading industries of new energy due to its green advantages; as one of the common components in the solar photovoltaic industry, crystalline silicon and other hard and brittle The application of materials is becoming more and more extensive, and the processing requirements are getting higher and higher. Diamond wire is an ideal method for cutting hard and brittle materials, especially precious hard and brittle materials. [0003] Diamond wire is the abbreviation of diamond cutting wire, which is a cutting wire made by coating tiny particles of diamond on the busbar. The diamond micro-sawtooth increases the cutting...
