Water-based paint has high environmental protection costs, and source control is more emission reduction

Nowadays, GAC Trumpchi, Yuehai Automobile, Baolong Automobile, Huizhou Dongfeng Motor, Fujian Longma, Chongqing Dima, XCMG, etc.
all use water-based paint, especially in some new energy vehicles and environmental protection industrial enterprises.
The environmental performance is favored by the market
.

In the spraying workshop of Pengcheng Helmet Co.
, Ltd.
in Jiangmen City, Guangdong Province, the spray guns in the hands of the workers were skillfully turned over, and the originally monotonous helmets instantly became colorful
.
What is surprising is that this production link, which was originally heavily polluted, did not produce much peculiar smell
.

"After changing the water-based paint, not only does it not affect the quality of the product, the smell is also very small, the production environment has been improved a lot, and there is no need to worry too much about the body when working
.
" The workshop worker said happily
.


It is understood that the water-based paint used by the workers is produced by Arto High-tech Materials Co.
, Ltd.
(hereinafter referred to as "Acto") in Heshan, Guangdong
.
This is currently the only domestic company that independently develops and produces water-based automotive paint
.

In the context of fighting the battle against pollution and winning the battle against the blue sky, the country has increasingly tightened the emission control of VOCs.
The promotion and application of water-based paint can not only reduce VOCs emissions from the source of production, reduce environmental pollution, but also effectively reduce environmental protection.
The end investment of treatment facilities has great development prospects
.

The end treatment is turned to the source control
to make the production equipment fully water-based, the production process is fully enclosed, and the exhaust gas treatment is fully environmentally friendly.

Walking in the Yatu factory area, it is found that the entire factory area is full of greenery like a garden, and the production workshop is all high-end modern intelligent equipment.
There is no choking smell of traditional paint companies in the air
.

"Whether it is the production environment or products, we take environmental protection as the top priority
.
" Feng Zhaojun, Chairman of ACTO, said that the company's production equipment ranks in the forefront of the industry in terms of environmental protection and intelligence.

.
Especially to meet the national environmental protection requirements, since 2006, the production of environmentally friendly water-based paint has been put into production.
After 12 years of water-based technology reserves, the environmentally-friendly water-based paint produced by it has become the benchmark of the industry's products
.

"Source emission reduction, process control, and end treatment are the main ideas for air pollution prevention
.
" Feng Zhaohua, director of ACTO, mentioned that in reality, many coating companies use the method of installing exhaust gas treatment equipment at the end in order to save trouble.
Governance
.
"Although the end treatment seems to be relatively cheap, the stability is not enough, and the environmental protection standards are constantly improving, and the cost of upgrading is actually not low
.
"
"In 2006, when oil-based paint was still on sale, we started to start water-based paint.
Research and development
.
" Feng Zhaojun mentioned that the company has full confidence in the development of environmentally friendly coatings and has invested more than 100 million yuan.
After 10 years of concentrated research and development, it finally achieved a breakthrough in the water-based product of the whole system, and it was officially completed and put into production in November 2015.
Using a fully automated, water-based environmentally friendly paint production plant, the production equipment is fully water-based, the production process is fully enclosed, and the exhaust gas treatment is fully environmentally friendly
.

ACTO currently owns all water-based products.
The overall performance of the products exceeds that of oil-based products, including product hardness and product gloss that the industry is worried about.
In particular, the core chemical properties of water-based products such as salt spray resistance and aging resistance are much higher than oil-based products
.

Chu Zili, deputy director of the Guangdong Provincial Road Transportation Administration, said when visiting ACTO that VOCs emission control requires the joint efforts of municipal and county governments at all levels and relevant personnel in the automobile maintenance industry to make rapid progress.
The "Thirteenth Five-Year Plan for Environmental Protection in Guangdong Province" It is proposed to strengthen the control of the source of VOCs pollution and accelerate the promotion and application of water-based coatings
.
“As the only domestic company that independently develops and produces water-based automotive paints, ACTO has played a good role in promoting the full use of water-based paints in the automotive maintenance industry in Guangdong Province within 5 years
.
”
ACTO’s efforts have also been recognized by the industry
.
At the first China Water Paint Festival in 2017, ACTO won the "Excellent Waterborne Automotive Paint Brand Award"
.
This is the recognition of ACTO by the industry, and also the affirmation and expectation of its promotion of the development of environmentally friendly water-based paint
.

Is the performance of water-based paint good?
Some indicators have surpassed oil-based paint.
The advantage is reflected in the environmental performance.
VOCs production is reduced by about 87%, and it can also reduce the investment in environmental protection equipment for end exhaust gas.

"Many people are used to thinking that the performance of water-based paint is not as good as oil-based paint.
This is not the case
.
" Feng Zhaohua According to the introduction, after years of research and development and practical application, ACTO water-based paint is not only comparable to oil-based paint, but some indicators even exceed oil-based paint
.
"It has very strong hiding power, and its strong adhesion can be applied to the full spraying of different substrates, reducing the number of sprayed layers and the amount of paint, saving time and efficiency
.
"
In addition, the data shows that the water-based paint sprayed products have a finer and more delicate touch.
Elasticity, its core chemical properties such as salt spray resistance, aging resistance, and loss of gloss are higher than oil-based products
.

The advantage of water-based paint is reflected in its environmental performance
.
“In the production process of oil-based paint, various organic solvents are used more and the amount of VOCs produced is relatively large
.
” Under the leadership of Feng Zhaohua, when the reporter visited the ACTO water-based paint production workshop, the smell here was very small
.
"Because no organic solvents are used, and measures such as equipment sealing and air collection are well done, VOCs emissions are reduced from the source of the product
.
"
It is understood that the VOCs content in the air can be up to when traditional oil-based paint products are constructed.
600g/L, the use of water-based paint can be reduced to 80g/L, and the amount of VOCs produced is reduced by about 87%
.
In addition, the water-based paint has a low odor and is very suitable for construction in a closed system.
It is easier to collect VOCs in a centralized manner
.
This feature also makes the VOCs concentration of the exhaust gas produced after the use of water-based paint is low, the air volume is small, and the investment of environmental protection equipment for the end exhaust gas is not high, which can save hundreds of thousands to several million yuan in equipment investment, and the daily operation of the facility Management costs are also relatively low
.

With the increasing requirements of workers on the production environment, oil-based paint has a heavy smell, and the corresponding production process is becoming more and more difficult to recruit workers
.
In contrast, the spraying process of water-based paint has a small smell, workers are more willing to use it, and companies are also easy to attract and retain talents
.

Guangdong Yuehai Automobile Co.
, Ltd.
is one of the users of ACTO water-based paint
.
The relevant person in charge of the company said that after the company switched to water-based paint, the smell was greatly reduced, the working environment was significantly improved, and the health of workers was clearly protected, which was praised by the workers.
In the end, the company changed the oil-based paint to water-based paint in the production process
.

After a certain auto repair factory in Shenzhen tried ACTO's water-based paint, the workers were reluctant to use oil-based paint, and eventually forced the company to switch to water-based paint
.
"Workers are particularly willing to use water-based paint, which also helps to reduce the risk of occupational diseases
.
"
It is understood that the performance of water-based paint is sufficient to meet the requirements of traditional oil-based paint.
Although the product price is higher than that of oil-based paint, the company’s investment in environmental protection facilities is small and daily The operating cost is low, and the overall cost is the same as that of oil-based paint
.
Moreover, the use of water-based paint is conducive to improving the environment and retaining talents, allowing enterprises to truly rest assured and standardize their operations, without worrying about unqualified environmental protection governance, and no worries about the future
.

From the perspective of government environmental protection supervision, the use of water-based paint can realize the controllable effect of atmospheric environmental protection, reduce the source of VOCs generation by 87%, process collection rate of more than 90%, and exhaust gas treatment of more than 90%, reducing corporate environmental pollution control Pressure helps to stabilize emission standards
.

To be promoted in many fields.
It is
expected to be used in the automotive and new energy and industrial fields in the future.
At present, it is difficult to promote it.
It is necessary to consolidate industry consensus and conduct industry trials
.
At the end of the 1990s, mature foreign water-based paints entered the Chinese market, initially mainly for repairing Paint products, with the gradual improvement of China's environmental protection requirements, China's automotive refinish paint is gradually changing from solvent-based to water-based
.

Since 2014, China's water-based refinish paint has entered a rapid growth model.
From 2015 to 2017, the average annual growth rate of China's water-based refinish paint increased from 15% to nearly 20%.
In 2017, the sales volume of water-based refinish paint in China accounted for the total consumption of refinish paint.
Already more than 3%
.

"National policy support is a key factor in promoting the expansion of the water-based refinish paint market, and the growth of passenger car sales and car ownership is the fundamental reason driving the growth of the water-based refinish paint market
.
" Industry insiders predict that the overall volume of China's water-based refinish paint market is still Will expand year by year
.
Compared with other countries, China's water-based paint market has a leading growth rate and is expected to become the world's most important water-based refinish market in the future
.

At present, resolutely winning the battle to defend the blue sky is the top priority of environmental protection work
.
It is foreseeable that in the future, whether in the field of home improvement or the automotive industry, environmental protection coatings are already an irreversible trend
.
As the representative of China's refinish paint field, ACTO has already prepared for the water-based refinish paint market.
After 12 years of development, water-based paint has expanded from refinish paint to other fields
.

On May 4, 2017, the establishment ceremony of ACTO High-tech Water-based Materials Division was officially launched, focusing on promoting the application of water-based paint in the automotive, new energy, and industrial fields
.

"Frankly speaking, the current promotion is still difficult
.
" Feng Zhaojun said frankly that due to the prejudice against water-based paints, market acceptance is still insufficient and it is difficult to form economies of scale, making water-based paints more expensive and restricting their promotion
.

In this regard, industry insiders urge that with the increasing pressure on air pollution control in my country, it is necessary to consolidate industry forces.
Enterprises should be self-disciplined and take the lead in action.
For example, coating manufacturers should take the initiative to produce water-based environmentally friendly coatings, and coating or VOCs generation companies should Actively use water-based environmentally friendly coatings, reduce emissions from the source, and combine the scientific methods of process control and end-of-pipe comprehensive management to achieve truly environmentally friendly production and assume social responsibility
.
"It is recommended that the government, industry associations and related departments strengthen the source control and source emission reduction of VOCs, give full play to the professional experience of outstanding companies, and conduct pilot projects and promote them in major industries
.
