Description
technical field:
The invention belongs to secondary resource comprehensive utilization technique field, be specifically related to a kind of method for preparing enhancing aluminum-base composite material by silicon carbide particles with crystalline silicon cutting waste material.
Background technology
Along with the exhaustion day by day of Nonrenewable energy resources and the people continuous enhancing to environmental protection consciousness; the global solar industry entry period of high speed development, and as the crystal silicon chip of one of photoelectric conversion device of solar cell because its cost is higher, the situation that supply falls short of demand appears greatly in demand.The crystal silicon rod obtains required crystal silicon chip by the multi-wire saw technology, at present except normal consumption, and the loss and become the cutting slug in the process of processing cutting of nearly 50% crystal silicon rod.Cutting liquid as the solar level crystalline silicon is divided into two kinds substantially, a kind of oiliness cutting liquid formed by organism, a kind of is the water-based cutting liquid formed with silicon carbide, polyoxyethylene glycol etc., because the second cutting liquid has nontoxic, nonirritant, have good water-solublely, and with many organic constituentses, good intermiscibility arranged and be widely used.In solar silicon wafers line cutting process, use silicon carbide as medium, the granularity scope of silicon carbide is 1-12 μ m, whole mechanism is to make silicon carbide impact continuously and healthily the silicon rod surface, utilize rigid characteristic and the sharp corner angle of silicon-carbide particle that silicon rod is blocked, this process can be accompanied by larger heat of friction and discharge, and must guarantee that mortar has good mobility and takes away in time cutting heat to guarantee the surface quality of silicon chip.
Cutting liquid is after being used certain hour, thereby because making cutting liquid lose cutting power, the increase of the wearing and tearing of silicon carbide corner angle wherein and silicone content thereof becomes the cutting waste material, these waste materials can be by centrifugal at present, filter, flotation etc. are to polyoxyethylene glycol wherein, oarse-grained silicon carbide, silicon powder is reclaimed, representative is that Chinese patent application CN200710018636.9 discloses a kind of method that reclaims silica flour and carborundum powder from the cutting waste mortar: with organic solvent, carry out solid-liquid separation, solid-state sand material is carried out to gas flotation, obtain the silica flour of certain purity, further this silica flour is carried out to liquid floatation and gravitational segregation, again the silica flour sub-elected is carried out to pickling, obtain highly purified silica flour, the powder mix of the carbonization silicon-metal simultaneously gravitational segregation obtained carries out magnetic separating, obtains the silicon carbide powder that size range mainly is distributed in 5-12 μ m.Removal process is as follows:
And the superfine silicon carbide micro powder that granularity is less than 5 μ m makes it sell at a low price or accumulation deposit because cost recovery is high, technical requirements is high and purposes is little etc., become enterprise and be badly in need of one of source of pollution that solve.
Enhancing aluminum-base composite material by silicon carbide particles is a kind of advanced composite material grown up the seventies and eighties in 20th century, there is mechanical property and the good advantages such as workability such as excellent hot strength, high-wearing feature, high specific stiffness due to this material, obtained in recent years tremendous development.Silicon carbide is a kind of non-oxide ceramic material of excellent property, be widely used as reinforced particulate and prepare metal-base composites, therefore silicon carbide powder has obtained new purposes, is mainly used in the every field such as automobile brake disc, engine piston connecting rod, wheel casing, bullet train and precision instrument in aerospace landing gear, war products, automobile making.
At present; the preparation of enhancing aluminum-base composite material by silicon carbide particles; what adopt is that powder metallurgical technique is mixed into base substrate by silicon carbide micro-powder and aluminium base micro mist; carry out pyroprocessing under gas shield in electric furnace; typical technique is that silicon-carbide particle is mixed at 200～300 purpose metal-powders with granularity; being 120～150 ℃ in temperature range increases gradually pressure and obtains base substrate to 400Mpa, 300～400 ℃, 500～670 ℃ respectively thermal treatment obtain the finished product.
And the silicon-carbide particle granularity of using in existing technique is larger, thereby make the consistency of silicon carbide and metal-powder poor, the composite property obtained is general, and the particle diameter that reduces silicon carbide can make cost increase.Therefore, if, by the waste material utilization, the material that obtains excellent performance when reducing costs just can produce considerable economic benefit, this becomes current people's research and sends out the focus of opening.
