Description
Technical field
The utility model is to produce band with traditional reaction kettle using the equipment of automatic control production technology manufacture silver powder
The equipment of the artificial production technology manufacture silver powder of stirring has essential distinction.The silver powder performance manufactured is stablized, pattern control
Stablize, single batch output is big, and lot stability is good.
Background technique
The technique for producing silver powder at this stage is implemented: being restored using silver nitrate solution and ascorbic acid or formaldehyde etc.
Agent is homogeneously added into silver nitrate solution into reducing agent in fixed container under stirring, thus can be by the silver in silver nitrate
The silver particles for being reduced into certain partial size and shape precipitate, after fully reacting, precipitating it is complete it is complete after remove (or topple over or filter)
Liquid is also answered, sediment is filtered out --- then silver powder is cleaned for several times again with deionized water, until the deionized water that silver powder comes out
After electrical conductivity of solution is 100 μ s/cm.The silver powder cleaned up can add dehydrated alcohol and dispersing agent is dispersed with stirring,
Soft-agglomerated silver powder particle is dispersed into the particle that relatively independent nothing is united, places into 50 DEG C of vacuum ovens and toasts for 24 hours, it will
The residual of dehydrated alcohol and deionized water remove completely it is dry after at clean and dry powdery silver particles.Finally the method is produced
Silver powder out is manufactured into the silver paste needed in various electronic products, is widely used in conducting wire.This method is domestic
It is widely used, the reason is that simple process, equipment investment small scale, production cost and personnel requirement be not high.But its maximum disadvantage
It is the consistency between batch, i.e., repeated more difficult control.Because difficult hold of mixing speed and chemical reaction condition causes to criticize
Secondary stability is poor, while the batch of primary first-order equation is little, for example uses 3m3Reaction kettle as reaction vessel, the silver powder of manufacture is only
50 kilograms or so, quantity made from primary first-order equation is few, then with same technique go manufacture second batch, as a result often with it is previous
Batch difference, so that using often different on electronic product after silver paste manufacture, electrical property and appearance are in scanning electricity
Microscopic observation otherness is big, and Quality of electronic products is caused to have height, especially accurate solar energy silver powder more to require consistency
Repeatability will be got well.Therefore, we are to accomplish that silver powder used for solar batteries has higher quality guarantee, then utility model
Devise a set of completely new equipment.

The utility model controls the component that silver nitrate solution and reducing solution is added by computer；PH is replenished in time in reaction process
The amount of value debugging agent.The component for accurately controlling pumping, regulating valve etc. is removed using control device, realizes what every batch of processed
The consistency of silver powder；Simultaneously by the flow monitor in the sensor and each pipeline in reactor, real-time transmission data is real
Now quantitative addition and transmission, makes reduction reaction process have Intellectualized monitoring, so that the consistency for the silver powder that every batch of obtains
Well, it is minimum to observe otherness under scanning electron microscope for electrical property and appearance.
In order to solve the above technical problems, the technical solution that the utility model uses is:
The equipment that a kind of Automatic Control manufactures silver powder, including control device, characterized in that including the first branch and
