Some introduction of adhesive


Adhesives can be used for metal, glass, wood, paper, fiber, rubber, plastic and other materials bonded together, it has a rapid development and widely applications, as well as a significant impact on the improving of high-tech science and technology progress and people's daily lives. Therefore, the research, development and production of various types of adhesives are very important.

In order to satisfy specific physico-chemical characteristics, they add various auxiliary component called additives. For example, adding curing agent to make subject stick material forme network type or size structure and increase poly strength within rubber layer; adding curing promote agent or catalyst to accelerate curing and reduced reaction temperature; using antioxidant  to improve resistance atmosphere aging, hot aging, ARC aging and ozone aging; adding filler to give adhesive some specific nature and reduced cost; using toughening agent to reduce adhesive rigidity and increase toughness; diluent to improve the process of reducing the viscosity and prolong life, and so on.

Temperature resistance is one of the excellent characteristics of inorganic adhesives. Usually inorganic adhesive is used in 1500~1750, but Phosphoric acid copper oxide adhesive has a more wide range temperature resistance which can be used 180~1400. By the way, bonding technology is a non-destructive connection technology, it improves the bonding interface and extende service life because of overall ability to withstand load.

There are some attentions about the storage. Each of these products have a shelf life. Acording to the international standard and national standard, store at room temperature 24 and Acrylic plastic is 20 degrees centigrade. The higher the temperature is, the shorter storage period acrylic product is. For water-based products, if the temperature is below 1 , it will has a direct impact on product quality.

Due to the adhesive can achieve same or dissimilar materials connections, the connection without stress, high adhesive strength, easy to realize combining automation, etc, it is widely used in all areas of national economy.  The rapid development of the national economy also provides a broad space for the development of the adhesives industry. Adhesive industry in addition to the continued rapid growth of production and marketing in China, adhesive technical level is also rising, a large number of advanced level products are developed. The trend is multi-functional, modification, and the applications focus towards emerging industries such as new energy, energy saving and environmental protection trend.
