Adhesive Development Trend
Because the adhesive has the advantages of connecting the same kind or different materials, no stress concentration of the joint parts, high bonding strength, easy to realize the automation operation, etc., it is widely used in various fields of the national economy and has become an indispensable part of the national economic development. Chemical products. The rapid development of the national economy has also provided a broad space for the development of the adhesive industry. China has now become a major producer and consumer of adhesives and adhesive tapes.
China's adhesive industry started in the 1950s and formed its first production climax in the 1980s. In the past ten years, with rapid development, it has entered a new era of rapid development.
The synthetic adhesive industry in the developed countries of the world has entered a highly developed stage. The average growth rate in the 1990s was about 3%, while the average growth in China was 19.5%. After 2008, adhesive has become one of the fastest growing key industries in China's chemical industry.
From 2007 to 2011, the compound growth rate of sales revenue and total profit of the adhesive industry reached 24.52% and 38.56% respectively. In 2011, China's adhesive industry achieved sales revenue of 92.753 billion yuan, a year-on-year increase of 33.25%; total profit reached 6.112 billion yuan, an increase of 59.40%. It is estimated that the sales revenue of the adhesive industry will exceed 100 billion yuan in 2012.
In addition to the continuous rapid growth of production and sales scale, the adhesive industry in China has continuously improved the technical level of adhesives, and developed a large number of products that have reached the advanced level at home and abroad, and presented products in the direction of modified, reactive, multifunctional, nano-type, etc. Development and application areas are focusing on the development trend of emerging industries such as new energy, energy conservation and environmental protection.
Many of the current adhesives contain a large amount of highly volatile solvents that not only endanger people's physical and mental health, but also destroy the ozone layer in the atmosphere. It has attracted the attention of the public and the government, which naturally brings a new development trend to the adhesive industry, namely the development of solvent-free adhesives.
Nano-adhesives are an important part of the material field. The development of nano-adhesives is likely to grab a technical commanding height in the "nano economy" that swept the world. Nano-adhesives will become a dazzling new technology star.
When an adhesive has multiple functions at the same time, its application value tends to increase sharply, so multi-functional adhesive is one of the development trends of the adhesive industry.
An important feature of the development of the mainland adhesive industry is that sales growth continues to be higher than output growth. With the expansion of domestic adhesive production scale, product quality and quality improvement, China's adhesive products have gradually entered the international market, with both export volume and foreign exchange earnings. Substantial growth. Adhesive applications continue to expand, from the main use in wood processing, construction and packaging industries to clothing, light industry, machinery manufacturing, aerospace, electronics, transportation, health care, post and telecommunications, storage and many other fields.
In particular, in recent years, China's trademarks, labels and advertising stickers have been widely used, accelerating the development of the corresponding adhesive varieties, and the amount of glue used in the automotive industry, the electronic appliance industry, the footwear industry, the construction industry, and the food packaging industry has grown rapidly. China's largest consumption of adhesives and sealants is in the building materials and decoration industry, followed by the packaging industry. The fastest growing is the transportation industry and the assembly industry.
At present, the market characteristics of China's adhesive industry are: rapid growth in output and sales, new products and new equipment, and rapid development of foreign-funded enterprises. Environmentally-friendly adhesive production technologies and products are highly valued, but the supply of general-purpose medium and low-end products exceeds demand. The phenomenon is still serious, the market competition is fierce, some important raw materials and high-tech products need to be imported, some important raw materials are in short supply, coal, electricity, oil and other energy supply are tight, and the price increase is too large, which has aggravated the production cost burden of enterprises.
