The so-called electric nozzle heater is divided into two types according to the structure. One is to spray the surface of the heating tube directly with the fluoroplastic material, and the other is to put the PTFE sleeve on the outer layer of the stainless steel heating tube or the copper heating tube. Fluoroplastic sleeve).
The surface sprayed Teflon is more suitable for the anti-fouling heating place, and is the best choice for anti-rust and anti-scaling, such as rice cooker and thermos liner. Teflon, which is made of PTFE casing, is a new type of electric heater that is resistant to strong corrosion and is used for heating various corrosive liquids. It has excellent aging resistance and good flexural properties, and is designed with low surface load (1.5w/cm2).
The PTFE heating pipe joint adopts a fully enclosed epoxy resin seal, which can effectively prevent liquid damage to the wiring part, acid and alkali resistance, etc., while the non-heating section and the overheating safety protection system are completely customized according to the customer's needs, intact It ensures that the heater is not easy to burn, has a long service life, is completely sealed, does not corrode, does not leak electricity, has grounding protection, and is safe and reliable. The applicable temperature is below 110 °C. (heating in a very thick liquid, must be configured with stirring), is corrosive liquid heating of electroplating, electrolysis, degreasing, pickling, electroless nickel plating, anodizing, aluminum pouring, smelting, chemical, pharmaceutical, food, etc. , condensation, evaporation, concentration, etc. The best heater choice!
Precautions for use:
1. The working voltage must not exceed 10% of the rated value; the relative humidity of the air is not more than 95%, and there is no explosive or corrosive gas.
4. The metal cast nozzle heater should be positioned and fixed, and the effective heating area must be closely attached to the heated body. When it is found that there are dust or contaminants on the surface, it should be cleaned and reused in time to avoid heat dissipation and shorten the service life.
5. The magnesium oxide powder at the outlet end of the electric heating element is protected from the infiltration of pollutants and moisture in the place of use to prevent the occurrence of electric leakage accidents.
