New Ideas For Wenzhou Synthetic Leather Industry

< p > > a href= "//www.sjfzxm.com/news/index_p.asp" > Wenzhou < /a > the pformation and upgrading of synthetic leather industry has a long history.

The industry has created a new sample of pformation and upgrading in terms of collective upgrading and individual breakout.

< /p >

< p > for example, Hong Deli, Changfeng, Jin Dali, Xinda and other enterprises, or developing waterborne polyurethanes or improving production lines, and making efforts to achieve environmental protection from different angles are typical individual breakout. The 5 synthetic leather enterprises settled in Longgang new town development area of Cangnan and 1 "three wastes" management enterprises jointly build a comprehensive 5+1 model for the comprehensive treatment of the three wastes. The introduction of the concept of circular economy is a collective upgrade.

"P" recently, the Wenzhou environmental protection bureau responsible person interviewed by reporters said that synthetic leather "new samples" showed the direction and path of industry upgrading.

Wang Yongkang, President of the Wenzhou synthetic leather business association, also believes that the advantages of the "new sample" are very obvious.

This year, with the support of the municipal environmental protection department, the top water has been effectively controlled, and a large "odorous" source has been cut off, so as to achieve energy saving and emission reduction, and achieve triple win in terms of social, environmental and economic benefits.

< p > June 2010, Wenzhou Hong Deli resin Co., Ltd. took the lead in the world's top 500 enterprises, Dow group, to jointly develop waterborne polyurethane production projects.

Waterborne polyurethane is a water substitute for toxic chemical solvents to produce polyurethane, which itself is a green product. Therefore, the pollution problem of traditional synthetic leather industry is effectively solved in the process of synthetic leather production.

It is understood that the technology has been successful in the pilot test, the synthetic leather industry frankly, if the technology is mature and promoted, the synthetic leather industry will not have the word "pollution control" after that.

< p > also in the "water" aspect, there are Wenzhou Changfeng < a href= "//www.sjfzxm.com/news/index_c.asp" > artificial leather < /a > Co., Ltd.

Changfeng company established a cooperative relationship with University of Science & Technology China in 2011, and successfully developed the effluent polyurethane artificial leather bass. After dry veneering, it became an environment-friendly green artificial leather.

The product was identified as a new product of the provincial level in January of this year through the appraisal of Zhejiang provincial industrial new products.

In April, the product was awarded the national patent, and after the mass production, it was tested by international authorities without DMF.

The company is a long-term supplier of IKEA group, the world's top 500, and has become a new paradigm for the pformation and upgrading of the synthetic leather industry.

Wang Ming, chairman of Zhejiang jindali Leather Co., Ltd. introduced that according to the different characteristics of the products, the air volume and wind pressure of the exhaust gas recovery system should be adjusted. Through the repeated measurement and exploration of the wind pressure of the exhaust outlets, a reasonable negative pressure could be formed at the main emission point of DMF exhaust gas, so that the exhaust gas could be efficiently recovered and processed. P

The company closed the production line to purify the air of the workshop, greatly improving the recovery rate, and the waste water was reused after treatment.

This approach was extended to the whole industry after the promotion of business associations.

< p > Wenzhou Xin Dali Leather Industry Co., Ltd. has designed a new ammonia removal tower. The new tower has increased 4 meters higher than the original old ammonia removal tower, and the diameter of the tower has increased from 1 meters to 1.2 meters, and three condensing equipment has been added outside the tower.

Since the new tower was put into operation in August last year, the water temperature of the tower top water has dropped to about 30 degrees Celsius, and the contents of two methylamine and COD in the effluent meet the discharge standard. If the product line is recycled, it will save 200 thousand yuan in water a year.

< p > Wang Yongkang thinks that for every person in charge of synthetic leather enterprise, every detail should reflect energy conservation, environmental protection and consumption reduction. This is a necessary concept.

Many enterprises aim at the different characteristics of synthetic leather production, carry out targeted pformation and upgrading, and ultimately promote the pformation and upgrading of the whole industry.

< /p >

< p > < strong > collective upgrade: the performance is very 5+1 < /strong > /p >

< p > when some synthetic leather enterprises have made significant breakthroughs in pformation and upgrading, some synthetic leather enterprises that have reached a consensus of upgrading have built a very 5+1 mode of industrial upgrading in Lu Pu, Longgang.

Settled in the new town of Longgang Lu Pu synthetic leather < a href= "//www.sjfzxm.com/news/index_s.asp" > Industrial Demonstration Zone < /a > 5 enterprises, namely Zhejiang tin bull Industrial Co., Ltd., Zhejiang Huayi synthetic leather Co., Ltd., Zhejiang Olympic synthetic leather Co., Ltd., Zhejiang Hong Mao Leather Co., Ltd. and Wenzhou KangBo synthetic leather Co., Ltd., each invested 18 million yuan, jointly invested in the construction of three wastes centralized processing enterprise Wenzhou Wenzhou Jie environmental protection Industrial Co., Ltd.
