Description
Technical field
The invention belongs to sewage treatment area is and in particular to a kind of clean environment-friendly flocculating agent and its production method.
Background technology
At present, in the various carbody shell such as automobile, motorcycle and electromotor, the spraying process of various electric appliance casing, by
The paint that manual or robotic spray gun is sprayed, only about 50～70% paint can fall on the housing of required spraying, changes speech
It, there are about 30～50% cannot be sprayed on housing or being wasted, the paint that this part is wasted was commonly referred to as oil spout
Paint.It is to ensure that the important step that painting process is smoothed out to crossing effectively processing in time of spray paint.This is because: to oil paint
For, cross spray paint in spray room circulating water chennel, stick in pipeline and the pump housing, result in blockage when serious；For water paint, mistake
Spray paint causes particle substantial increase in circulating water chennel, and recirculated water is muddy, causes foam to generate in a large number, can cause micro- simultaneously
Biological growth, circulating water body fouls so that spray room working environment deteriorates.
In order to maintain paint spray booth's performance, improve painting operation environment, so that recirculating water purification system is normally run for a long time,
Using suitable method, coating cloud must be processed.It is mainly mechanical curettage method currently used for the method clearing up spray painting and coagulate
Poly- agent method, and the former is big due to paint viscosity, coating cloud can not thoroughly be removed, and this method treatment effeciency is low, although the latter can be right
Coating cloud clearance reaches more than 90%, but because commercially available lacquer mist coagulant processes the expensive of waste water, is difficult to be promoted
Use.
Flocculating agent cohesion speed on existing market is slow, and after coating cloud condenses in bulk, the viscous effect that disappears is bad, and upper machine pressure slag glues
Roller, and most flocculating agent has special odor, not environmentally, using rear water turbidity or even corrupt smelly, indirectly affect water
Matter.
Content of the invention
For existing flocculating agent cohesion speed slow, the viscous effect that disappears is bad, polluted-water the problems such as, the present invention provides a kind of new
Type clean environment firendly flocculating agent and its production method.
The present invention provides a kind of clean environment-friendly flocculating agent, consisting of: by weight percentage, organically-modified swelling

Preferably, above-mentioned clean environment-friendly flocculating agent, consisting of: by weight percentage, organic modified bentonite
13%, modification of chitosan 20%, modified starch 10%, soda 5%, sodium bicarbonate 2%, balance of water.
Wherein, in above-mentioned clean environment-friendly flocculating agent, described preparation method of organic modified bentonite is: by 60-
The bentonite of 70 weight portions and cetyl trimethylammonium bromide Hybrid Heating 15-30min of 30-40 weight portion, make organic
Modified alta-mud.
Wherein, in above-mentioned clean environment-friendly flocculating agent, it is pure that described soda and sodium bicarbonate are analysis.
The present invention also provides a kind of production method of above-mentioned clean environment-friendly flocculating agent, comprises the following steps:
A, add sodium bicarbonate and soda in water after stir 5-10min, regulations solution ph is 8-11；
B, towards in step a solution add modified starch, stir 10-20min, regulations solution ph be 5-7；
C, towards in step b solution, adding modification of chitosan, stirring 15-20min, until forming stable suspension；
D, towards in step d suspension, add organic modified bentonite, stir 6-7h, regulations solution ph is 7-8, be obtained newly after pack
Type clean environment firendly flocculating agent finished product.
Wherein, in the production method of above-mentioned clean environment-friendly flocculating agent, each raw materials by weight meter, organically-modified
Bentonite 10-15%, modification of chitosan 15-20%, modified starch 10-12%, soda 3-5%, sodium bicarbonate 1-2%, balance of water.
The invention has the benefit that the invention provides a kind of clean environment-friendly flocculating agent and its production method, being somebody's turn to do
Flocculating agent dissolves in water and is uniformly dispersed, and absorption amount of paint is big, and catalytic reaction activity is high；Cohesion speed is fast, and disappear viscous excellent effect.
This flocculating agent is raw materials used to be easy to get, biodegradable, will not secondary pollution water body；Produce agglutinant valency of fine quality using the method
Honest and clean, consumption is few, low cost, and equipment investment is few, simple in production process operation, has greatly saved production cost.
Specific embodiment
