Description
Technical field
The invention belongs to the chemical agent technology; Relate to the chemical agent that a kind of application circulating water system chemical treatment method is used; Specifically, be a kind of green lacquer mist coagulant that is used for the application circulating water system, said treatment agent is applicable to oil-base paint and water-miscible paint circulating water treatment.
Background technology
This product is mainly used in automobile production painting workshop and the appliance shell treating processes of spraying paint.Spraying paint is important step in automobile, the household electrical appliances production process.Nearly 20%～60% paint can't be sprayed on the car body in the painting process, and this part paint was called the oil spout lacquer.As far as oil-base paint, crossing the oil spout lacquer can be at the pipeline of the spray room recycle system, and bonding is adhered on wall even the recycle pump, and what influence was produced normally carries out; As far as water-miscible paint, cross the oil spout lacquer and can cause spray room circulating water system dirt and microbial growth.Therefore, the oil spout lacquer effectively handles to crossing of producing of vehicle spray painting is to guarantee that automobile production effectively carries out, and reclaims poisonous paint particle simultaneously, follows the bad paint spray booth that utilizes and crosses the requisite link of oil spout lacquer carrier water system.Energy-saving and emission-reduction and environment protection were significant during it was produced automobile, household electrical appliances.The commercially available prod is summarized as follows,
1, selects highly basic usually for use,, join in the application recirculated water, made and spray paint in high alkalinity solution, accomplish unsticking, come-up like sodium hydroxide.At present, the type treatment agent adopts the direct addition method of aqueous sodium hydroxide solution.From the beginning of the sixties, alkaline process is widely used in application industry.But the problem that alkaline process exists is the development that is accompanied by coating paint, and its structure tends towards stability, and alkaline process can not be deviate to spray paint fully; And strong alkali solution is to corrosion on Equipment and field staff's injury, and the later stage water treatment has all brought huge harm.
2, carbamide also is a kind of lacquer mist coagulant commonly used at present.The type product mainly leans on the entrained polyfunctional group of trimeric cyanamide, reacts rapidly with the paint molecule, when using simultaneously with the come-up agent, can obtain good unsticking, slag making effect.Because formaldehyde is toxic, and in polymerization trimeric cyanamide and formaldehyde, can not remove monomer formaldehyde residual in product fully, so this type product has certain toxic side effect.The type product is satisfactory for result for oil-base paint, but along with being widely used of water-miscible paint, the type product can't reach the ideal effect.
According to the strategy of sustainable development, advance Green Chemistry, research and develop functional, the direction that nontoxic free of contamination coating cloud detackifier is a paint industry.The green water treatment agent that exploitation has independent intellectual property right; Progressively to replace current a large amount of carbamide class application circulating water treatment chemical agent that adopts both at home and abroad; Advance the development of Green Chemistry medicament; Active development is used formaldehydeless application circulating water treatment medicament, is significant, and be this technical field engineering technical personnel's an important research topic.
