Steel coating, is expected to fully enable water-based coatings!

The source of air pollution in steel mills is mainly surface painting process, and now the surface coating of steel mills, all using traditional paint spraying, resulting in a pungent odor, pollution exceeding the standard, environmental assessment does not pass, the Environmental Protection Bureau often come to check, seriously affecting the production and development of enterprises.
, the main reason for the failure of the steel mill environmental assessment
steel mill products must be surface coating before the factory, mainly anti-rust, anti-corrosion. The coatings used are mainly chlorine polyethylene anti-corrosion coatings, iron-red phenolic resin anti-rust coatings and a small amount of alcoholic acid and coatings

. These coatings in the process of spraying, curing to produce a large number of organic exhaust gases, not only pungent taste, but also caused serious environmental pollution.
, the hazards of spraying high-concentration VOCs coatings in steel mills
1. Serious air pollution
coatings are widely used in steel mills, and the use of organic volatiles into the atmosphere of a large number of emissions, so that the atmospheric environment has become a victim of enterprise development.
expert analysis, the traditional coating contains a large number of VOCs, in the process of use will wave out a large number of toxic chemicals, including stupid, formaldehyde, xylene are toxic and harmful chemical gases, in China, the annual use of coatings have 7 million tons of organic volatiles, discharged into the atmosphere, thus, VOCs on the air pollution of the huge "influence" can be seen.
the effects of air pollution on human health are fatal. According to the latest WHO statistics, 7 million people died from "air pollution" globally in 2012, more than double the previous figure. This equates to one in eight deaths worldwide caused by air pollution.
2. Serious waste of resources
more than 50% of the components of traditional coatings are organic solvents extracted from petroleum, in the film-forming process, organic solvents will evaporate into the air, which results in a large amount of waste of resources.
experts point out that, for example, a paint company with a capacity of 125,000 tons would consume 200,000 tons of oil per year, equivalent to 268,000 tons of more quasi-coal per year. And this is only a company's data, if the industry's annual paint production consumption of oil add up, the total amount of oil consumption will be huge.
3. Security
VOCs are flammable and explosive gases, in the production and use of a very large security risk, just like a hidden bomb around people, at any time will threaten the safety of users. Currently, VOCs are included in the National Environmental Management Register for Hazardous Chemicals.
in the past, there have been numerous cases of explosions in the use and storage of traditional coatings, and tragic cases of maiming and even death are distressing.
4. Fatal "occupational disease"
experts believe that workers in high concentrations of VOCs gas, the safety of their lives is even more worrying, workers working in the environment like a dangerous "mine zone." Coatings contain a large number of toxic volatile substances, including formaldehyde, benzene, xylene and so on. Studies have found that long-term exposure to organic compounds, light makes people prone to fatigue, memory loss, inattmental concentration, heavy fatigue, emotional instability, self-control and autonomy decline and other lasting personality and emotional changes, more serious people have intellectual impairment, dementia, inability to work and so on. Long-term repeated exposure to low concentrations of benzene can cause chronic poisoning, damage to the nervous system, hema production system. It also affects the growth and development of the next generation, for example, leading to reproductive malformations. However, these severe symptoms, which appear to outsiders, are only "minor symptoms" of occupational diseases in the eyes of workers.
workers must wear production-specific masks when working on the shop floor to reduce inhalation of organic volatiles during the production process. However, for long-term production operators, wearing a mask to prevent the inhalation of toxic substances has a limited effect. Incidents such as fainting and vomiting during work are common, while workers who have been engaged in paint production for many years suffer from occupational diseases and even lead to permanent disabilities of some workers.
, the best alternative to steel mill coating
the best alternative to traditional coatings for new environmentally friendly coatings, such as water-based industrial paint. Water-based coatings are all water-based thinners, do not use organic solvents, do not contain organic solvents, do not contain benzene, toluene, xylene, formaldehyde, free TDI toxic heavy metals, non-toxic non-irritating odor, harmless to human body, do not pollute the environment, paint film plump, smooth operation, flexible and water-resistant, wear-resistant, aging, yellow-resistant, dry fast, easy to use.
, water-based industrial coatings product performance advantages
1. Fast-drying
Water-based industrial coatings from the innovative film-forming mechanism, the use of new water-based polymer, the use of advanced production processes, optimize the cross-link density of coating film, improve the mechanical and weather resistance of coating film, while discarding the current foreign common incomplete Supporting process, not only to achieve a water-wide high-gloss color loss paint once coating (no need to spray the hood varnish), reduce the operation process, energy saving and consumption reduction, drying process is simplified, only (75 degrees C) 20 minutes drying can be, room temperature can also be self-drying.
2. Construction is simple
without the use of special spraying tools, the use of ordinary spray gun can carry out high-quality construction work, from primer to finish all water as a solvent, simplifying the cleaning process of equipment tools. Water as a cleaning agent, reduce the consumption of organic solvents, eliminate the excessive use of benzene solvents caused by the surrounding environment pollution, and to a large extent reduce the occurrence of occupational diseases, more conducive to the health of front-line operators.
3. Energy saving and consumption reduction
water-based industrial coatings from primers to finishes, all water as a thinner, cleaning agent, fundamentally eliminate the storage consumption and use of organic solvents.
water-based industrial coatings and does not contain harmful ingredients such as xylene and butyl acetate, reducing environmental pollution.
water-based industrial coatings improve drying conditions, reduce energy consumption, reduce equipment requirements, while reducing safe production, fire prevention and a range of other work requirements.
