At a time when the world economy is sluggish, companies are under great pressure to survive, and the plastics industry is already very competitive. How to reduce product costs and improve product competitiveness is a core issue facing every enterprise, and electric energy is in the plastics industry. A large proportion of product costs, plastic companies are naturally very concerned about saving electricity costs and reducing production costs. At present, the energy-saving retrofit technology for electromagnetic heating of plastic machinery has attracted the attention and use of many enterprises. In fact, electromagnetic induction heating technology appeared more than 80 years ago, and it has been applied in many other industries, such as: heat treatment of steel, household induction cooker, etc. . It is only used in the energy-saving transformation of plastic mechanical heating or in recent years. The basic principle is to use the principle of electromagnetic induction to generate 20~25KHz super-audio electromagnetic waves, and generate eddy currents through the induction of the plastic barrel itself, because this method belongs to The heated body itself generates heat, and the thermal efficiency can reach more than 90%, and completely solves the problem that the heat resistance of the conventional resistance heating method needs to be low through air conduction. The thermal efficiency of the resistance heating method can generally only reach 60%, and some are as low as 30%, so The electromagnetic heating method can obviously save electricity for plastic machinery, and at least 30%, and some machines with low thermal efficiency can reach 80%.
冉 ç”µç£ electromagnetic heating because of professional, so achievements!
