Synthetic Innovation Technology: Environmental Products Can Also Be Priced Together.

Environmentally friendly products usually mean higher prices.

Xie Zhenming's pricing for waterborne polyurethane products is "basically unchanged from traditional products".

This is an environmental protection technology that should be used in synthetic leather industry.

"As long as we go to the synthetic leather workshop, we can smell a pungent smell.

I stayed in the lab, and I had to go out in half a day. "

Xie Zhenming regrets: how can employees and technicians endure in such an environment?

Besides, the traditional organic solvents are very easy to cause fire in addition to the serious pollution of the environment.

Xie Zhenming also has some partners who have suffered losses.

"There must be a substitute technology for safety and environmental protection, and this technology will also be accepted by the market." it is this belief that supports the expert in waterborne polyurethane resin, who is a farmer and a half-way engineer. He has spent more than 20 years researching and popularizing this technology.

It is because of this belief that he will set a price equal to traditional products.

Similar technologies abroad are usually 4 to 5 times more expensive than the original ones.

In March 28th, Xie Zhenming's "waterborne polyurethane resin instead of the traditional solvent based polyurethane resin should be applied to the achievement pformation project in the field of synthetic leather" and won the third Golden Bridge Award.

The Golden Bridge Award for two years is a supplement to the science and Technology Progress Award and the highest award in the field of technology market in China.

The award has been approved by the Ministry of science and technology, and the National Award Office has authorized the establishment of the China Technology Market Association.

"Every time we go to tanneries, we are all in a toxic environment.

Every time I hear a tannery explode and catch fire, it inspires a strong sense of responsibility and produces a strong driving force, which is to make the tanning enterprises clean production and safe production.

China is a large country of synthetic leather production. Its output accounts for over 70% of the world's total, and it needs more than 1 million tons of polyurethane resin annually.

For a long time, synthetic leather has been produced with chemicals containing a large number of organic solvents. 70% of them are toxic and harmful solvents, which not only cause a lot of waste of organic solvents, but also seriously pollute the environment, cause great harm to the workers' bodies, and cause safety production.

The synthetic leather made from waterborne polyurethane resin is not only highly simulated skin, non-toxic, environment-friendly and high physicochemical properties, but also has no toxic and harmful gas emissions during production and processing. It can fully realize clean production and safe production. It can save a lot of organic solvents and save a lot of valuable resources for the country.

Therefore, its social and economic benefits are very significant.

However, this technology development is not smooth sailing.

There are many difficulties in the application of waterborne resins in synthetic leather.

On the one hand, it comes from the inherent problems of water-borne resin itself, such as the large surface tension of water, difficult to spread, slow evaporation of water, difficult to dry, and problems that need improvement in the development and production process, such as waterborne resin wear resistance, scratch resistance, aging resistance, acid and alkali resistance, solvent resistance, hydrolysis resistance and so on. It must be broken through one by one before it can be applied to synthetic leather.

On the other hand, it also comes from equipment problems, tanning process problems, water auxiliaries material matching problems, and the application of release paper, etc. all these problems must also be solved. Only in this way can we truly say mature products.

"Every time we go to tanneries, we are all in a toxic environment.

Every time I hear a tannery explode and catch fire, it inspires a strong sense of responsibility and produces a strong driving force, which is to make the tanning enterprises clean production and safe production.

Xie Zhenming said.

"In recent years, the company has not made much profit every year, but we have all invested in the development and expansion of waterborne resins.

This is also an important aspect that can come out of difficulties. "

Before 2000, Xie Zhenming was engaged in waterborne polyurethane production for 10 years.

"After 2000, we met with some professional friends of the University of science and technology, and discussed the feasibility of waterborne polyurethane for synthetic leather."

Xie Zhenming said.

There is no doubt that it has gone through numerous difficulties from selected projects to successful promotion and application.

The waterborne polyurethane used for proofing in the laboratory will be given free to the tannery's waterborne polyurethane, which should be calculated in terms of tens of tons.

"We first sent a resin to a Wenzhou agency in 2003, a group of three tons.

It started to work, and later found problems. Of course, money could not be recovered.

In addition, some enterprises have processed products into garments with our products, but after exporting to foreign countries, they found that all of them were glued together, which resulted in great losses to customers, and of course we paid a price for that.

Xie Zhenming said.

This road is not easy to walk.

Xie Zhenming often recalled the words of Liu Xiuru, director of the Department of pollution control of the State Environmental Protection Administration.

Do you know what you are doing?

You are doing something good for the society and for mankind.

As long as the application of waterborne resin is solved, the problem of pollution control in the whole industry is solved.

A group of experts and people of insight also give full support to this technology.

"Some partners are not afraid to take risks in the application of waterborne resins. They have done a lot of work at all costs, so that the reality of waterborne PU resin can be successfully applied to synthetic leather in dry production line."

Xie Zhenming said.

2007 is the best year for the application of waterborne PU resin.

On the one hand, Xie Zhenming further improved the waterborne resin and made the application simpler. On the other hand, it enhanced the research of high physical properties waterborne resin, so that the synthetic leather produced by waterborne polyurethane resin had better physical properties than solvent type, thus greatly promoting the application process.

"In recent years, the company has not made much profit every year, but we have all invested in the development and expansion of waterborne resins.

This is also an important aspect that can come out of difficulties. "

Xie Zhenming said.

"At present, almost all equipment can be used in the application of resin supplied by Jiabao company, but from a higher level, almost all the equipment needs to be improved."

Last year, synthetic leather made from waterborne resin was exhibited at Hongkong Leather Fair and Shanghai International Leather Exhibition.

Some famous companies both at home and abroad have already started bulk ordering.

Compared with traditional synthetic leather produced by solvent processing, synthetic leather produced by waterborne polyurethane has not only general physical properties, but also non-toxic, environmental friendly, breathable and moisture permeable and better handle.

The comprehensive implementation of waterborne resin in the industry is Xie Zhenming's long cherished wish. But how far is it?

"As long as the climate is formed in popularization and application, this process will be very fast.

We popularized waterborne polyurethane resin on leather, from 1.5% in 1991 to 95% in 1997, and it took six years before and after.

Synthetic leather is not that long.

Because the synthetic leather industry is relatively concentrated and easy to promote, and the government's intervention is more intense and effective.

Moreover, water-based PU resin manufacturers now have more than 100 domestic enterprises, and have the ability of development and application, but the cost performance needs to be further improved.

Xie Zhenming said.

Many tanneries are very unclear about the use of waterborne polyurethane to improve equipment.

If tannery does not improve the equipment, it will affect the production efficiency.

"At present, almost all equipment can be used in the application of resin supplied by Jiabao company, but from a higher level, almost all the equipment needs to be improved."

Xie Zhenming said.

One is the length and temperature control of the oven.

The temperature of the oven controlled by the solvent resin is lower, and the temperature of the waterborne polyurethane is relatively higher, and the oven is lengthened. Only in this way can the production efficiency be not affected.

The two is the problem of coated knives. As long as the production line is permitted, water-based polyurethane processing can be made by multi knife and thin coating. This will not only improve the production efficiency, but also improve the quality. Of course, the coating head must be more precise.

Three is conditional development of infrared heating.

"Because waterborne polyurethane is non flammable and non explosive, it is possible to use infrared heating.

In this way, not only can greatly improve the production efficiency, but also do not need a long oven, which can greatly shorten the length of the workshop.

Xie Zhenming said.

At an industry conference held in Guangzhou, Xie Zhenming brought the synthetic leather produced by waterborne polyurethane to the conference and introduced the product to the vice president of Bayer, Germany's conference organizer.

When he heard that "waterborne polyurethane synthetic leather is excellent in wear resistance and scratch resistance, and it is acid resistant, alkali resistant, resistant to hydrolysis and solvent resistant, and made of leather garments can be washed or dry cleaned", the vice president asked: How did you make such a high physical property?

Xie Zhenming replied, "because I do not have the same kind of water based resin used in synthetic leather for comparison, all the comparisons are made with the physical properties of the solvent type resin.

Therefore, many properties of our waterborne resins have reached some of the products that have already exceeded the solvent type.

This is an indisputable fact.

Moreover, Xie Zhenming has always firmly believed that the application of his technology is not only environmental protection, but also has cost advantages.

Environmentally friendly products can still have price advantages.

"Because the price of solvent is bound to rise, the price of water will not go up too much.

As long as the application of waterborne resin increases, the cost will further decline. "

Xie Zhenming said.

He is a director of Zhangjiagang Jiabao environmental protection resin material Co., Ltd., who has been engaged in waterborne polyurethane research for nearly 20 years.

In March 28, 2008, he won the third "Golden Bridge Award" because "waterborne polyurethane resin instead of traditional solvent polyurethane resin should be applied in the field of synthetic leather production pformation project".

The project has been verified by a series of pilot units. The synthetic leather not only has high simulation skin properties, non-toxic, environmental protection and high physical and chemical properties, but also has no toxic and harmful gas emissions during production and processing. It can fully realize clean production and safe production. It can save a lot of organic solvents and save a lot of valuable resources for the country.

Therefore, its social and economic benefits are very significant.

Before 2000, waterborne polyurethane applied to leather was mainly studied.

After 2000, the feasibility of waterborne polyurethane for synthetic leather was studied.

In 2005, Zhangjiagang Jiabao environmental protection resin material Co., Ltd. was founded, and scientific research cooperation with Anhui University and related enterprises at home and abroad was carried out extensively.

At present, the waterborne polyurethane products for coating and flocking have entered the market in bulk.

The waterborne polyurethane resin for synthetic leather which has filled the domestic blank has also been put on the market in batches.
