Preparation and application of single dosage paint mist coagulant

Abstract

The invention relates to a single dosage paint mist coagulant prepared by using a polyethylene wax emulsion as a main component. The single dosage paint mist coagulant is applied in paint mist absorption circulating water of an engineering machinery coating workshop, combines with paint particles in the water and floats up, and effectively solves the problems of poor flocculation, sediment of circulating water, and the like, guarantees to long-term, safe and effective operations of the circulating water. The polyethylene wax emulsion is an ethylene-acrylic acid copolymerized wax emulsion being an EAA type polyethylene wax emulsion. A relatively optimum proportion of reagents is as follows: 20.0% -25.0% of the ethylene - acrylic acid copolymer wax emulsion, 1.0% -2.0% of dicyandiamide, 0.5-1.0% of the surfactant and 72.0%-78.5% of deionized water.

Description

Technical field: [0001] The invention belongs to the technical field of environmental pollution control and is mainly applied to a wet-type paint mist removal circulating water system in a painting workshop. Background technique: [0002] In the automobile, home appliance, furniture, construction machinery and some plastic processing industries, most of the painting operations adopt modern spraying technology, and are carried out in closed container spray booths or paint workshops, and are equipped with corresponding air supply and exhaust systems. Wet paint mist removal system . The main purpose of this wet paint mist removal system is to remove the overspray paint mist to protect the health of the on-site painting workers and prevent the overspray paint mist from polluting the parts to be sprayed. The wet spray booth often used in painting operations uses water as an absorbent to form circulating water in the spray booth. Its working principle is: the paint mist is in co...
