Electric heating plate is a kind of electric heating equipment. It uses electric heating alloy wire as heating material, mica soft plate and other materials as insulating material, and the outer layer is covered with heat conducting plate made of stainless steel and other materials. The laboratory heating plate is widely used in the laboratory. The heating plate has a high security system, which includes fixed safety circuits, overheating display and error display.
A heating electronic thermometer can also be installed in the heating plate, which can achieve high-precision temperature control effect. Functionality, safety and durability are the three main characteristics of laboratory heating plates.
1.Principle of heating plate
The heating material of the electric heating plate is electric heating alloy wire, and its working principle is very simple, which is the basic electric heating effect. When the electric heating plate works, the current passes through the electric heating alloy wire, and the electric heating alloy wire will generate heat, convert electric energy into heat energy, and conduct it to the outer shell. The electric heating plate is designed with insulating material to ensure that the current during the operation of the electric heating alloy wire will not cause hidden danger to the user.
2.The advantages of electric heating plate
The electric heating plate is mostly a thin and thin plate-like design with a simple structure and uniform heat dissipation, which is easy to install and use. The electric heating plate uses stainless steel, ceramics and other materials as the outer shell. The electric heating alloy wire is enclosed inside the electric heating plate, so it is closed heating. There is no open flame and no odor during heating. It has good safety and is suitable for various tasks. surroundings.
3.Classification of electric heating plate
There is currently no clear classification of electric heating plates. The common electric heating plates in the market are stainless steel.
Electric heating plate, ceramic electric heating plate, silicon rubber electric heating plate, carbon crystal electric heating plate and carbon fiber electric heating plate, etc., the main difference is that the outer shell material is different or the inner heating material is different, such as stainless steel electric heating plate and ceramic electric heating plate are the material of the shell Different, the rest are different heating materials.
4, the use of electric heating plate
There are many advantages of electric heating plates, so they are widely used in production and life. From ordinary floor heating and electric thermos bottles to maintaining the experimental environment temperature in the laboratory, the use of electric heating plates is indispensable. At present, electric heating plates have been widely used in various fields such as industry, agriculture, civil, national defense, science and technology, and medical and health.
