Abstract
The invention discloses a cutting wire which can improves the cutting fractured surface and reduces the cutting cost, comprising a steel core wire. A copper zinc alloy plating layer is coated on the surface of the core wire, the plating layer contains 66 percent to 70 percent of copper parts by weight, and the residual is zinc; and in the cutting wire per kilogram, the weight of the copper zinc alloy plating layer is 7 grams to 9 grams. The flexibility of the cutting wire is better, and when the solar wafer is cut, the wire breaking ratio is lower, therefore, the cutting cost is greatly reduced; and furthermore, the cutting fractured surface of the solar wafer cut out by using the cutting wire is smoother, and the quality of the solar wafer is improved.
Description
Technical field
The present invention relates to a kind of cutting silk.
Background technology
At present, be used to cut the cutting silk of solar wafer (single-chip and polycrystalline sheet), directly come branch that plurality of specifications is arranged by its line, be respectively 0.11,0.12,0.14,0.16 and 0.25 millimeter, its margin of tolerance is ± 0.003 millimeter, and its structure comprises: the steel heart yearn, and the surface of heart yearn is coated with ormolu coating, described coating contains the copper of 62.5～65.5% weight, and all the other are zinc; In every kilogram the cutting silk, the weight of ormolu coating is 5～6 grams.The solar wafer that this cutting silk cuts out, the cutting section of wafer is rough, and in cutting process, the cutting silk is very easy to disconnected, causes cutting cost higher.
Summary of the invention
Technical problem to be solved by this invention is: a kind of cutting silk that improves cutting section, reduces cutting cost is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of cutting silk comprises: the steel heart yearn, and the surface of heart yearn is coated with ormolu coating, and described coating contains the copper of 66～70% weight, and all the other are zinc; In every kilogram the cutting silk, the weight of ormolu coating is 7～9 grams.
The invention has the beneficial effects as follows: thickness and the copper in coating, zinc content of cutting silk of the present invention by adjusting coating, the intensity and the pliability of this cutting silk have been strengthened, make the wire broken rate of this cutting silk when the cutting solar wafer reduce greatly, thereby greatly reduce cutting cost; And, with the cutting section smoother of a this cutting solar wafer that cuts out, improved the quality of solar wafer.
