Functional Overview

Water-based paint is difficult to separate from water due to its miscibility with water, and it produces a lot of foam, which affects production. Water-based paint mist coagulant is a kind of chemical agent raw material specially used to deal with the treatment of water-based paint waste water and the removal of paint (paint slag) in circulating water. Water-based paint mist coagulant is a common additive for spray treatment of circulating water in the paint industry. The main function is to eliminate the viscosity of the paint mist, condense the paint mist into floc and float it on the surface of the circulating water, which is easy to salvage and remove (or automatically control the slag removal).

Instructions Overview

Water-based paint mist coagulant is divided into agent A and agent B. The two agents are used together (generally the ratio of agents A and B is 3:1–2). First add a certain amount of agent A (generally 2‰ of the amount of paint circulating water) in the paint circulating water. Agent A is added at the inlet of the circulating water, and agent B is added at the outlet of the circulating water for painting (agents A and B must not be added at the same place at the same time). Generally, the dosage of the agent is 10-15% of the amount of overspray. Usually, the agent can be added manually or automatically by the metering pump. According to the amount of overspray, the flow rate and displacement of the metering pump can be adjusted.

Instructions

1. It is recommended to completely clean the tank and change the water once before using the agent, so that the effect will be better. After changing the water, first adjust the water quality with sodium hydroxide to control the 8-10PH value range, and add 1.5-2.0 kg per ton of water Around sodium hydroxide.

2. Add paint mist flocculant A to the turbulent water circulation of spray booth every morning after water change (ie, spray booth pump motor); after adding the medicine, produce and spray paint as usual, and add paint mist flocculant B before work. The paint residue is usually salvaged (that is, the poly paint tank); the suspended paint residue can be salvaged after work.

3. Dosing ratio: The dosing ratio of paint remover and suspending agent is 1:1, and each time the amount of paint sprayed in the circulating water of the spray booth reaches 20-25 kg, add 1 kg each. (This ratio is a pre-estimated value. The actual dosage needs to be adjusted slightly according to the type of paint and viscosity on site. Because the old paint block adsorbed in the spray room pipeline will consume part of the potion, so the amount of drug used in the initial period of dosing should be slightly. Too large)

4. No need to adjust PH value.

Handling and storage

1. Avoid splashing the liquid into the eyes. If contact with the liquid, immediately flush the contact area with plenty of water.

2. Store paint flocculant AB in a cool place and avoid direct sunlight.

3. Cannot be stored in alloys of aluminum, iron and copper.
