Carbon fiber (carbonfiber is called for short CF) is the tencel material of the high strength of a kind of phosphorus content more than 95%, high modulus fibre.It to be piled up along fiber axial direction by organic fibers such as flake graphite crystallites to form, the micro crystal graphite material obtained through carbonization and graphitization processing.Carbon fiber " soft outside but hard inside ", quality is lighter than metallic aluminium, but intensity is higher than iron and steel, and has characteristic that is corrosion-resistant, high-modulus, carbon fiber has the strong stretching resistance of material with carbon element and the large feature of fiber softening machinability two concurrently, and carbon fiber is a kind of new material of excellent in mechanical performance.Carbon fiber tensile strength is about 2 to 7GPa, and its proportion is also lighter than aluminium, and less than 1/4 of steel, specific strength is 20 times of steel.Under same intensity, the carbon fiber cutting wire length of same weight can reach 20 times of steel wire.
Realizing in process of the present invention, inventor finds prior art, and at least there are the following problems: to produce solar silicon wafers, due to silicon wafer thickness on the photoelectric transformation efficiency of solar cell without impact, therefore improve silicon materials utilization rates and become one of important channel reducing silicon chip processing cost.In cutting, cutter seam (sliced materials loss) has very important relation with abrasive sand granularity and cutting steel wire diameter, and the sliced materials being the cutting steel wire of 0.140mm as diameter is lost in less than 200 μm.For reducing the loss treating cutting material, the diameter of cutting wire is constantly reducing, and only has thinner cutting wire could form narrower cutting gap, reduces the loss of material to be cut.Simultaneously in order to accelerate cutting speed, cutting wire is needed to apply higher pressure and run at faster speed.These all propose new higher requirement to the intensity of cutting wire.
Summary of the invention
The utility model mainly solves the technical problem existing for prior art: provide a kind of novel cutting wire, multi-line cutting machine can be run under higher cutting speed, maybe can apply higher pressure, increase work efficiency.Under identical Tensity size requires, cutting machine can adopt the cutting wire of thinner diameter, and improving stock utilization to be cut becomes and cut down finished cost.Cutting machine adopts with the cutting wire of abrasive coating, and its working (machining) efficiency is more than the several times of traditional free abrasive multi-wire saw.
For achieving the above object, the technical solution of the utility model is achieved in that
The utility model provides a kind of cutting wire, it is characterized in that: described cutting wire is carbon fiber.
Further, described carbon fiber is continuous filament yarn.
Further, the cross-sectional diameter of described glass fibre is 0.001-1.00mm.
Further, the cross section of described carbon fiber is circular or sub-circular.
Further, described carbon fiber outer surface has abrasive coating, and described abrasive coating comprises abrasive grain, and described abrasive grain adopts plating or bonding mode to be fixed on carbon fiber.
Compared with the existing technology, carbon fiber cutting wire can adopt possesses higher cutting speed than the steel wire of same diameter to the utility model, applies higher pressure and runs at faster speed.Under identical Tensity size requires, carbon fiber that diameter is thinner can be adopted as cutting wire, treat cutting material cutting.Abrasive material is anchored at carbon fiber cutting wire on the surface, can participate in cutting directly, not re-use mortar, its working (machining) efficiency is more than the several times of traditional free abrasive multi-wire saw, and effectively extends the service life of cutting wire, significantly reduces cutting cost; Decrease the pollution to environment on the other hand.In addition, the utility model can be applied to the field such as electronics industry, photovoltaic industry, and the scope of application is very wide, is worthy of popularization.
