Development trend of new products and new technology of adhesive
|
|
With the deepening of research in the field of adhesives, the trend of development of world synthetic adhesive performance for the following three aspects. Construction technology and application of glue equipment constantly updated, the adhesive proposed higher requirements. In order to improve the product quality, simplify the operation process, improve the construction efficiency, developed countries have developed a series of special equipment, not only to provide a better construction method, also put forward higher requirements for the adhesive industry, for its sustainable development has created an important condition.
Two, high performance composite adhesive growth is very fast. High performance platform into adhesive, one is the product requirements at the same time with good mechanical performance and functionality; two is the production line of the requirements of the process has operability. At present, because of the construction industry and the automotive industry, the requirements for the quality of the adhesive, the construction conditions are demanding, developed countries are committed to the development of high performance, high quality of the new type. In recent years, the annual growth rate of synthetic adhesive production in the developed countries is very low, and the output of some varieties is declining, but the sales have increased rapidly. The reason is that the high performance synthetic adhesive has brought great economic benefits. High performance synthetic adhesives including epoxy, silicone, polyurethane and the new type of modified acrylic adhesive, etc..
Three, the development of environmentally friendly synthetic adhesive. With the strict environmental protection laws and regulations, the developed countries vigorously develop water-based and hot melt adhesive. In 1998, the developed countries in the synthetic adhesive market, water-based adhesive accounted for 50%, hot melt adhesive accounted for about 20%, while the solvent type adhesive only accounted for 20%. To low polluting water-based glue and hot melt global synthetic adhesives market will be the future, environment-friendly synthetic adhesive will be market marketable goods. At present, there are three aspects of the development trend of the synthetic adhesive industry in China: 1 is the high performance rubber species will develop rapidly. 2 is the environmental protection type adhesive will become the mainstream of the synthetic adhesive; 3 is the synthetic adhesive industry is speeding up the scale structure the reasonable adjustment, realizes the synthesis adhesive industry large-scale reorganization, causes the production essential factor to the superiority enterprise to concentrate, realizes the adhesive production the intensification, the regulation. |
