Is the surface of the ceramic electric grill really ceramic?

- Sep 28, 2020-

Ceramic surface spraying is used to form a ceramic coating on the surface of the substrate, which plays a role in wear-resisting and anti-corrosion. According to the process, Wuxi Binhu District Napu Machinery divides ceramic spraying into two types, one is plasma spraying and the other is thermal spraying. Spraying ceramic coating is to use special equipment to form high hardness and dense ceramic coating on the surface of the substrate by spraying process.

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.

The volume resistivity is the quotient of the DC electric field strength in the insulating material and the steady-state current density, that is, the volume resistance per unit volume. The volume resistivity can be used as a parameter for selecting insulating materials, and 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 DC electric field intensity and the linear current density in 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 characteristics of the surface contamination 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, and the measured surface resistance value mainly reflects the degree of contamination on the surface 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, it can be convenient for us to carry, which can bring us a lot of convenience, here it is recommended to choose the kind of folding barbecue furnace.

Purchase according to material. Barbecue grills on the market are made 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. Therefore, it is recommended to choose 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 the factor of the number of barbecues must also be considered. Therefore, the size of the barbecue can be determined according to the number of barbecues each time when purchasing, so that everyone can eat a delicious barbecue.

Whether with oil guide and anti-smoke device. When grilling, the meat will drip oil, the oil dripping on the hot stone will smoke, and the smoke will produce bad taste when it sticks to the food. Therefore, the stove should have some kind of equipment to catch the oil, and then let the oil flow out of the stove.

Whether with a thermometer. It is often seen in barbecue recipes what temperature and how long to bake. If there is no thermometer, you can only rely on guessing. In this way, it is difficult to judge whether the food is cooked.
