A lot of users don't know what is the color of the color in the hot runner mold heater. Everyone will subconsciously think that the chemical products are toxic, and worry about whether it hurts the human body.
1. What is the white powder in the coil heater?
The white powder in the heating tube is magnesium oxide powder, which has excellent thermal and insulating properties.
Second, what is the role of white powder in the hot runner heater?
(1) Insulation and heat conduction, the heating wire is the heating element is also for the human body, the magnesium oxide powder is isolated from the metal casing to ensure that the surface of the pipe body is not charged;
(2) Protecting the heating wire from external forces;
(3) It does not react with the heating wire and the metal casing, and can withstand extreme changes in temperature without bursting due to sudden temperature changes;
(4) The heat resistance is high, and the coefficient of expansion of the heating wire is close, and the heating wire is restricted to ensure no displacement in the heating pipe production process.
3. Is the white powder in the hot runner heater toxic?
(1) The magnesium oxide powder in the mold heating element is non-toxic, it is a odorless, odorless, non-toxic white amorphous powder, belonging to environmentally friendly materials;
(2) Magnesium carbonate, magnesium oxide powder and talc powder are commonly used lubricants for athletes and are harmless to the human body;
(3) Even if it is inadvertently swallowed, in addition to a very specific allergic constitution, magnesium oxide enters the stomach and reacts with hydrochloric acid to become magnesium chloride, which is present in seawater. Magnesium oxide has the function of being used as an antacid, a laxative, neutralizing gastric acid, and neutralizing gastric acid.
Heating element hot runner are widely used in various sectors of the national economy to heat air, liquid and solid media. They have achieved good economic effects in industrial and agricultural production and people's lives. What are the uses of heating pipes? The details can be summarized as follows:
1. People's life:
(1) Indoor heating and insulation, air conditioners, heaters, heaters, etc.;
(2) cooking noodles, rice cookers, electric kettles, electric ovens, etc.;
(3) cleaning and cosmetic aspects, electric irons, electric water heaters, etc.;
(4) Medical and health aspects, household sterilizers, etc.
