China is the world's largest shoe producer and exporter, and the shoe industry has always been the hardest hit by pollution. The traditional production mode of high energy consumption and low output not only makes shoe companies waste a lot of resources, but also pollute the environment. In addition to the rise of labor costs, rising raw material prices, exchange rate changes and the transfer of orders, China's footwear industry is experiencing severe challenges in the development and environmental pollution. Footwear companies must know how to choose the right adhesive to avoid or lessen this type of pollution.
With the country attaches great importance to energy conservation and emission reduction, relevant laws and regulations have become more and more perfect, people's understanding of their own health has gradually improved, and the water-based adhesives have been continuously entering people's vision. Previously, academicians of Chinese Academy of Sciences and Fujian Institute of Material Structure, the director of the Institute, Hong Maozhen, answered: China is currently the world's largest footwear producer, exporter and consumer, with adhesive shoes occupying most of the market. At present, 90% of the adhesives used in China's footwear industry are solvent-based adhesives, and the most important source of pollution is the unreasonable selection of its shoe adhesives.
Most of the organic solvents are volatile organic compounds. The large-scale use of organic solvents not only directly triggers the occupational diseases of the contacts, but also the volatilized gas produces a photochemical reaction under the action of ultraviolet rays, which will produce secondary pollutants such as aldehydes to form photochemical smog, thereby stimulating human eyes, respiratory tract, causing headaches, red eyes, laryngitis, lung disease and other respiratory diseases. Therefore, as far as the current situation is concerned, water based adhesive and green manufacturing are the general trend. Water-based polyurethane shoe adhesive developed by Guangdong Good Resin Technology Co., Ltd., which does not contain organic solvents, is non-toxic, odorless, non-flammable, non-polluting, and friendly to human body and environment. Currently widely used in the country, the water-based shoe adhesive has a high solid content. Compared with the solvent based one, the labor cost and the material cost are greatly reduced, and the corresponding viscosity can be adjusted according to the needs of the user. Merchants generally believe that the product is easy to apply glue, of high bonding strength, and overall reduce the overall cost.
