Environmental Technology Introduction
In the era of big environmental protection, do we really need to use paint mist coagulant containing formaldehyde?
Among the products for the treatment of spray paint wastewater, a large proportion of the products are organic two-component type. The main component of the debinding agent is formaldehyde polymer, and formaldehyde is a very harmful substance to the human body. June 2004 It was included in the list of carcinogens by the World Health Organization on the 15th. In many companies that pay attention to the physical and mental health of employees, this unfriendly product has been turned away. Natural nano-mineral materials have become the first choice for people as a debonding agent for water curtain spray paint workshops.
Relying on our years of research and accumulation in the field of nano-mineral materials, our company has developed a new type of green and environmentally friendly paint mist coagulant. Compared with products with chemical components, this product has the characteristics of good debinding, clear water, and wide application fields, and it will not be affected by pH changes during use. No additional substances such as pH regulators need to be added. After the water is cleared, the paint slag will float up quickly. If it is matched with the company's supporting slag removal equipment, it will be more convenient and quick, saving time and effort.
The amount of paint mist coagulant used is related to paint characteristics, system design, and the amount of paint falling in circulating water, but it is mainly related to the amount of paint falling. Generally at the stage of testing the dosage, the professionals of the company will gradually adjust the most economical dosage according to the actual medication status and effect. Generally, the order of addition to wastewater is to add agent A and then agent B. The treated circulating water can be changed once in March-June.
Addition calculation base:
Paint mist coagulant A: the amount of paint falling (the amount of paint falling into the water) = 1: 10-1: 20; paint mist coagulant A: B is added at a ratio of about 1: 1, or it can be slightly changed according to the type of wastewater Adjustment.
Paint mist coagulant for water treatment materials
Paint mist coagulant is mainly used to treat circulating wastewater in the spraying industry. It can capture the over-sprayed paint entering the circulating water, wrap and penetrate the paint drops, destroy the functional groups of the paint, completely eliminate the viscosity, make the paint slag completely float, and make the circulating water in the spray booth clear and transparent. No odor, can be used for a long time without frequent water changes. In addition, it can also significantly reduce the COD content in water, which can greatly reduce wastewater treatment costs. It is non-corrosive, and the pipelines and systems will not be blocked, which can prolong the service life of the equipment and save equipment maintenance costs. In particular, the paint mist coagulant with natural mineral bentonite as the main component has the characteristics of good treatment effect, environmental protection and wide application, and is a new type of environmental protection treatment agent.
