Abstract
The invention provides a water treatment agent having good adhesion-losing and agglomerating functions to paint mist generated in the constructions of solvent-borne type and water-based paints. The water treatment agent is mainly applied to a wet type paint mist removing circulating water system in a paint shop. The water treatment agent has a simple production process and a low cost, uses a biodegradable material as a main raw material, avoids the secondary pollution generated in water during medicament application, and effectively protects the environment.
Description
Technical field:
The invention belongs to the environmental pollution treatment technology field, be mainly used in application workshop wet type and remove in the coating cloud circulation.
Background technology:
In automobile, household electrical appliances, furniture industry and partly plastic processing industry, painting operation mostly adopts modern spraying technology, in closed container formula paint spray booth or painting workshop carry out, and be equipped with and send accordingly, the exhaust system wet type is removed the coating cloud system.The main purpose that this wet type is removed the coating cloud system is: remove over-sprayed paint fog, the staff's that sprays paint to keep the scene intact health prevents that over-sprayed paint fog is to be painted pollution.The normal wet type spray chamber that adopts utilizes water as absorbent in painting operation, constitutes spray chamber circulating water.Its operation principle is: coating cloud contacts with cascade or shower water, and paint is eluted in the water and forms paint particle and taken away by water.After adopting special process to isolate paint, water continues to recycle.
In order to keep the operation of recirculated water long-term safety, cross and spray paint and from recirculated water, to separate.This just requires coating cloud to be separated with convenient by abundant unsticking; The inharmonious process of paint is carried out at aqueous phase; Usually need in water, add specific water treatment agent; Make the paint that carries in the water fully inharmonious and from water, separate smoothly, adhere to paint spray booth's wall, pipe pump inwall, draught fan impeller, flume wall etc. and locate to result in blockage to prevent it.Inharmonious paint generally swims on the water surface, be suspended in the water or under be sunken in the water.
The existing water treatment agent that is used for application workshop recirculated water exists the formaldehyde that contains hazardous substance, and the coating cloud visbreaking is not thorough, can not biodegradation, recirculated water is produced secondary pollution, and influence the problems such as subsequent treatment of recirculated water.
Summary of the invention:
Product of the present invention is a primary raw material by shitosan and biodegradable dibasic ester, adds the aqueous solution that inorganic flocculation aid and surfactant are mixed with.This aqueous solution chitosan-containing 0.1-10%, divalent ester mixture 0-10%, inorganic flocculation aid 1-5%, surfactant 0.1-1%, water 84-98.7%.
Preferable proportioning is shitosan 0.1-3%, divalent ester mixture 1-3%, inorganic flocculation aid 3-5%, surfactant 0.1-0.3%, water 87.9-97.8%
Dibasic ester can be a dimethyl succinate, dimethyl glutarate, two or more mixture of dimethyl adipate or other biodegradable dibasic esters.Inorganic flocculation aid can be an aluminum sulfate, aluminium polychloride, one or more in liquid double-acid ferro-aluminum, iron chloride, the aluminium chloride.Surfactant is a kind of non-ionic surface active agent, and its mean molecule quantity is less than 10000.
The preparation method of this water treatment agent adds surfactant, divalent ester mixture, shitosan to stir successively in water, add inorganic flocculation aid at last and stir.
The application operating method:
(1) this water treatment agent should slowly add in the tank recirculated water porch that needs purify.
(2) this water treatment agent basis interpolation concentration is 0.2% (time that can guarantee aggregation is within prescribed limit) of quantity of circulating water.
(3) this water treatment agent must have additional dosage when normal spray painting operation, and it is proportional with the amount of spraying paint to replenish dosage; Be generally 1: 12～1: 20.
(4) this water treatment agent uses requires circulation pH value 6.5-7.5
(5) in time isolate the solid condensation product in the recirculated water after using this water treatment agent.
The present invention compared with prior art has the following advantages:
(1) this water treatment agent can make coating cloud thoroughly inharmonious, has solved equipment surface and has adhered to paint, and the lacquer slag muck amasss bottom land, stops up the problem at positions such as circulation line, nozzle, has reduced the cleaning difficulty in application workshop, has reduced the maintenance cost of relevant device.
(2) do not contain harmful substances such as formaldehyde in this water treatment agent, the application workshop condition is had no adverse effects.
(3) this water treatment agent is biodegradable, can not form secondary pollution to circulation.
The key technical indexes; After use should be invented medicament, the coating cloud clearance was greater than 90%; Lacquer slag come-up rate is greater than 85%; The organic solution removal effect is obvious; The lacquer slag of come-up is loose cellular caking, in water treatment, produces COD, BOD amount reduction 80-90% than common product.
