Is the surface of the ceramic electric grill really ceramic?

- Apr 17, 2020-

Ceramic surface spraying is used to form a ceramic coating on the surface of the substrate, which plays a role of wear resistance and corrosion resistance. Wupu Binhu District Napu Machinery divides ceramic spraying into two types according to the process, one is plasma spraying and the other is thermal spraying. Spray ceramic coating is to use special equipment to form a dense ceramic coating with high hardness by spraying process on the surface of the substrate.

 The volume resistance is the quotient of the DC voltage applied between the two electrodes placed on the opposite surfaces of the sample and the steady-state current flowing between the two electrodes.

 Volume resistivity is the quotient of the strength of the DC electric field and the steady-state current density in the insulating material, that is, the volume resistance within a unit volume. Volume resistivity can be used as a parameter to select insulating materials. The resistivity changes significantly with changes in temperature and humidity. The measurement of volume resistivity is often used to check whether the insulating material is uniform, or to detect conductive impurities that can affect the quality of the material but cannot be detected by other methods.

Surface resistance is the quotient of the voltage applied between two electrodes on a certain surface of the sample and the current flowing between the two electrodes after a certain period of time.

The surface resistivity is the quotient of the strength of the DC electric field and the linear current density at the surface layer of the insulating material, that is, the surface resistance per unit area. Surface resistivity is not a parameter that characterizes the characteristics of the material itself, but a parameter related to the surface pollution characteristics of the material. Because the volume resistance is always more or less included in the surface resistance test, the surface resistance can only be measured approximately. The measured surface resistance value mainly reflects the degree of surface contamination of the tested sample.

Consider whether the grill is portable. The outdoor barbecue grill is our own item, so it is best to consider this aspect when purchasing, which can be convenient for us to carry, which can bring us a lot of convenience, it is recommended to choose the folding barbecue furnace.

Choose according to material. Barbecue grills in the market are of various materials, and the prices are different. It is not necessary to buy expensive ones, but the service life of iron grills is definitely not very long, so it is recommended to choose the kind of stainless steel, which is stronger than iron Durable and not easy to rust.

Choose according to the size of the grill. Certainly some people think that the smaller the portable, the better, but you also need to consider the factors of the number of barbecues, so you can determine the size of the barbecue grill according to the number of barbecues each time, so that everyone can eat delicious barbecue.

Whether it has oil guide and anti-smoke device. When grilling, meat will drip oil, and the oil dripping onto high-temperature stones will cause smoke, and the smoke will produce a bad taste on the food. Therefore, the furnace should have some equipment to catch the oil, and then let the oil flow out of the furnace.

Is there a thermometer? On barbecue recipes, I often see how long to bake at what temperature. If there is no thermometer, you can only rely on guessing. In this case, it is difficult to judge whether the food is cooked.
