Principle of work of the present invention is as follows: coating cloud in recirculated water with a certain amount of electronegativity, after contacting with the lacquer mist coagulant A agent of positively charged, particulate by lacquer mist coagulant A agent wraps up, and loses viscosity after charge transfer, forms unstable fine particle, add after lacquer mist coagulant B agent, because lacquer mist coagulant B agent is long-chain net high-polymer structure, fine particles, by lacquer mist coagulant B agent strong adsorption, makes it form larger particles and floats, separated with water, thus purify water.
Using method of the present invention is as follows:
1, the preparation of solution:
Join first groove according to the total water amount in spraying equipment, by water per ton, add 2-3 kilogram of lacquer mist coagulant A agent and 2-3 kilogram of calculating input medicament of lacquer mist coagulant B agent, open water pump simultaneously, tank liquor is stirred, control the pH value of solution and (with test paper, test) between 6 ~ 8;
2, the interpolation of medicament:
The addition of lacquer mist coagulant should be determined according to kind and the consumption of paint, be generally the 10-30% of the consumption that sprays paint, and lacquer mist coagulant A Ji ︰ lacquer mist coagulant B agent is that 1 ︰ 1(paint consumption as workaday in certain is 300 kilograms, the addition of lacquer mist coagulant A agent and lacquer mist coagulant B agent is 30-90 kilogram so), after lacquer mist coagulant fully contacts, mixes with paint in water, paint slag Floatation Rate can reach more than 98%, more by hand or mechanical means the paint slag of floating is salvaged to the water surface;
3, quality control:
(1), while joining groove, first the water of each cell body is joined to the position of regulation, according to total Water, in the different location of recirculated water, add lacquer mist coagulant A agent and lacquer mist coagulant B agent, open water pump, to tank liquor circulation 10-20 minute simultaneously;
(2), open after class every day, should open water pump by the trough inner water 10-20 minute that circulates, then lacquer mist coagulant A agent and lacquer mist coagulant B agent are added with the method dripping continuously in different places;
(3), because volatilization or the other reasons such as tank liquor seepage naturally cause that tank liquor reduces, should add in time water to normal level of liquid, in order to avoid affect coating cloud flocculating result;
4, change groove: smelly in order to prevent bacterial growth and tank liquor, need regularly tank liquor to be changed, the general replacement cycle is: in 5-6 month winter, in 3-4 month summer, annual June, September, January need carry out tank liquor replacing in principle.
Result of use of the present invention is to such as table one.
Table one: high-efficiency environment friendly rust-preventive agent result of use is analyzed list
| Project | Do not use lacquer mist coagulant to process | Use lacquer mist coagulant is processed |
| Paint slag | Paint slag bonding, easily caking, precipitates, and is difficult for processing | Except the viscosity of the middle paint that anhydrates, paint slag cohesion floating, easily processes completely |
| Recirculated water situation | Recirculated water is muddy | It is limpid that recirculated water becomes |
| The COD content of recirculated water | COD content is more than 6000mg/L | COD content can drop to below 1000 mg/L |
| Circulating water quality | Stink is dense | Stink is eliminated, without foreign odor |
| Pipeline situation | Pipeline easily stops up, and water circulating pump and vacuum fan are easily killed damage, keeps in repair and change part cost high | Pipeline is smooth and easy, and the long service life of equipment can reduce maintenance and reduce accessory cost |
| Water curtain situation | Water curtain outlet is easily stopped up, and current skewness, causes a part of coating cloud not to be absorbed, and coating cloud can be extracted out and cause atmospheric pollution and the damage finished product that sprays paint with exhaust system | Water curtain is complete, evenly, makes to spray room paint quality and improves, and can not cause atmospheric pollution |
| Drag for slag | Paint slag precipitation, is easily attached on equipment, pool wall, and collecting paint slag wastes time and energy | Paint slag easily collecting, saves artificial |
| Environmental issue | The spray room recycle system is polluted because painting slag, easily makes dirty in spray room | Paint slag can not pollute spray house system, contributes to ISO14000 application authentication |
| Work peace | Spray room workshop air is muddy, has the problem of actual bodily harm | Spray room workshop air is good, helps output and benefit and promotes |
| Turnout | Because cleaning, change recirculated water and structure deteriorate, its rate of respraying is high, affects output | Can within 6-10 month, change water once, can often not shut down, the rate of respraying is low, contributes to output to promote |
