Description
Technical field
The present invention relates to siliceous fertilizer production technical field, specifically one kind is given up using solar energy crystalline silicon Buddha's warrior attendant wire cutting
The method that slurry prepares siliceous fertilizer.
Background technology
Important element of the silicon as content on the earth second, it is the fourth-largest battalion necessary to plant in addition to nitrogen, phosphorus, potassium
Support element.Supplement element silicon can form siliceous cell in plant in time in the growth course of plant, hence it is evident that enhancing is made
The disease resistance of thing, lodging tolerance etc..In addition, the presence of element silicon can also promote absorption of the plant to other nutritional ingredients,
Strengthen photosynthesis of plant, further to improve the yield of crop.At present, the siliceous fertilizer of in the market mainly has two kinds, one kind be with
Blast-furnace cinder is " solubility in citric acid " siliceous fertilizer of primary raw material, and its Determination of Soluble Silicon is low, and fertilizer efficiency is poor.It is another then be containing not year-on-year
" soluble silicon " siliceous fertilizer of example, can directly carry out foliage-spray, can also rush and apply or base is applied.
Although the fertilizer efficiency of Soluble silicon fertilizer mainly comes from commercially available apparently higher than " solubility in citric acid " siliceous fertilizer, its silicon source
Silicate product, production cost are higher.Chinese invention patent specification disclose a granted patent " a kind of liquid silicon fertilizer and its
Production technology ", Patent No. " ZL200810238522.X " is to be used as " silicon source " by raw material of industry potassium silicate or sodium metasilicate, in life
During production liquid silicon fertilizer is mixed to prepare by adding the auxiliary materials such as biochemical fulvic acid, chelating agent, trace element, urea.Its is main
Action component " soluble silicon " and other auxiliary materials are direct purchase gained, from cost, do not possess competitiveness.Therefore, seek
It is to solve the important channel of the problems such as high current siliceous fertilizer market price, small scale to look for a kind of new, cheap silicon source.
On the other hand, with the getting worse consumed excessively with environmental pollution of traditional energy, with crystal silicon solar electricity
The photovoltaic industry that Chi Wei is represented has obtained development at full speed in recent years.And crystalline silicon section is to prepare crystal silicon solar energy battery
One of important step.In recent years, perfect with Buddha's warrior attendant wire cutting technology, increasing production line is from original carborundum
Slurry cutting has made Buddha's warrior attendant wire cutting into.Buddha's warrior attendant wire cutting reduces the generation of silicon mud compared to mortar cutting, eliminate silica flour and
The separation problem of silicon carbide abrasive, but the recycling for cutting silica flour is still the emphasis problem of slice process.Due to Buddha's warrior attendant
A small amount of metal impurities are brought during wire cutting into so that it can not be used directly as the raw material of crystalline silicon ingot casting, at present
Mainly handle at a low price to relevant producer.From now on, with the constantly improve of environmental protection policy, it is also possible to carried out as Industrial Solid Waste
Handle and pay huge disposal costs.The great wasting of resources is so not only caused, while also add and prepare crystalline silicon electricity
The cost in pond.Therefore, the high-purity silicon powder in this diamond wire cutting waste material is reasonable urgently to be resolved hurrily using photovoltaic industry is turned into
The problem of.
" a kind of crystalline silicon diamond wire saw slug recovery is sharp again for the granted patent that Chinese invention patent specification is announced
Method ", Patent No. " ZL201610086247.9 " describe a kind of method for disposing diamond wire cutting waste material.This method
Mainly using the method for high melt come smelting high-purity silicon.But the production cost of this method is high, be only suitable for electricity price compared with
Low region, and cost of transportation is added, generalization is poor.
