An intelligent electromagnetic flowmeter generally has a set of coils and two electrodes. The function of the coil is to apply an electric field to the fluid. The flowing conductive liquid is equivalent to a conductor. According to Faraday's law of electromagnetic induction, when the conductor cuts the magnetic lines of force, a corresponding speed is generated. The proportional electromotive force, the role of the electrode is to measure the induced electromotive force, so only the electrode in the measuring tube is connected with the conductive liquid, and the other part is the inner lining. To ensure the insulation, the electromagnetic flowmeter can work normally.
The flame retardant masterbatch is also called the flame retardant masterbatch and the fireproof masterbatch. It is just to achieve the requirements of fire protection requirements for plastics and rubber products.As the flame retardant masterbatch (masterbatch) is used in the plastics, it has become an effective substitute for the traditional flame retardant in many aspects, such as the efficiency of flame retardancy, environmental protection, improvement of production efficiency, convenience and so on. It has been widely used in the various aspects of plastic granulation, extrusion, injection molding and so on.
If the metal pipe with the magnetic field is also in contact with the liquid, the short circuit between the conductive liquid and the metal pipe measured by the electromagnetic flowmeter will be electrically conductive, and the potential will be led away so that the electromagnetic flowmeter cannot measure the potential. Therefore, the interior of the electromagnetic flowmeter is lined. This article focuses on the characteristics and requirements of PTFE;
Teflon is the most stable chemical material in plastics. It is commonly known as “Plastic King†and has a wide range of high and low temperature applications. In addition to metal sulphate, fluorine and its compounds erosive it, such as strong acid, strong alkali, detergents and organic solvents do not work on it. It can withstand hydrofluoric acid with a concentration of 0 to 100% boiling and can work at a high temperature of 200 °C. The material is non-toxic and has excellent aging resistance, especially suitable for chemical and food fields.
Main performance: It is a plastic with the most stable chemical properties. It is resistant to boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia. It is also resistant to concentrated alkali and various organic solvents. Not resistant to chlorine trifluoride, high temperature chlorine trifluoride, high flow rate liquid fluorine, liquid oxygen, self-oxygen corrosion.
Maximum medium temperature: 150 ° C (special order required)
Scope of application: 1. Strong corrosive medium such as concentrated acid and alkali. 2. Hygienic media.
Lining material: polyperfluoroethylene propylene (F46)
Main performance: same as F4, wear resistance, anti-negative pressure ability is higher than F4.
Other features are basically equivalent to F4
