Wenzhou Shoe Materials Improve Technological Means To Solve Pollution Problems

It is understood that one of the sources of pollution in the traditional synthetic leather industry is the raw material, oil polyurethane, which is used in leather making. The polyurethane is made from toluene, xylene, acetone, acetic acid, ethyl ester and two methyl formamide (DMF) as the main solvent. There are certain toxic and auxiliary uses. The waste gas and waste liquid produced by the production are easy to pollute the environment.

"At present, the disposal of pollution discharge is mainly based on recycling and reuse, and the cost is higher.

If pollution can be eliminated at the source, it will be equivalent to process reengineering, which can achieve clean production throughout the whole process.

Hong Deli resin Co., Ltd., responsible person said, waterborne polyurethane, in short, is the use of water instead of toxic chemical solvents to make polyurethane, which itself is a non-toxic environmental protection product. Therefore, in the production process of synthetic leather, no toxic waste gas and waste liquid will be discharged, thus effectively solving the pollution problem of the traditional synthetic leather industry.

It is reported that the patent results of waterborne polyurethane resin were originally developed by the Dow group of the world's top 500 enterprises after more than 10 years of research and development.

The group's industry covers chemical, pharmaceutical and other fields, and last year its net sales amounted to US $60 billion.

As one of the 100 leading enterprises in our city, Hong Deli has produced 150 thousand tons of resin and exported to Russia, Korea and other countries and regions.

Under the global trend of green economy, Dow group wants to join hands with domestic enterprises to pform laboratory technology of waterborne polyurethane into industrial products.

After a nationwide selection of thousands of synthetic leather enterprises, the Dow group finally released Hydrangea to Hong Deli, and after 16 months of negotiations and negotiations, a cooperation agreement was reached.

Our city now has more than 100 large scale synthetic leather enterprises, more than 400 advanced production lines, and a daily production capacity of 5 million meters. Last year, the total industrial output value reached about 10000000000 yuan.

With the gradual elimination and upgrading of traditional synthetic leather technology, green and environmental protection have become the mainstream of the industry, and are bringing revolutionary changes to the application field of synthetic leather.

According to the experts, water-based polyurethane synthetic leather has been applied to shoe leather, clothing, automobile seats, interior decoration and so on.

"The successful signing of the project is the result of continuous emphasis on Technological Development and international cooperation by private enterprises in recent years, which will effectively promote the pformation and upgrading of the synthetic leather industry."

The relevant responsible person of the Municipal Economic and Trade Commission's external economic coordination office said that after the project was put into production, it will play a leading and exemplary role in improving the production process and improving the level of environmental protection and energy conservation in the synthetic leather industry.
