Magmeter liner selection should be selected according to the corrosiveness, abrasiveness and temperature of the measured medium. Hard/soft rubber is resistant to general weak acid and alkali corrosion. Temperature resistance is 65℃. Soft rubber has abrasion resistance. Polytetrafluoroethylene (PTFE) is almost resistant to strong acid and alkali corrosion except hot phosphoric acid. The temperature of the medium can reach 130℃. But it is not resistant to wear. Polyurethane rubber has good wear resistance. But it is not resistant to acid and alkali corrosion. Temperature resistance is also poor. The medium temperature is less than 65°C. Liner MaterialsFunctionsApplicationsHard rubber1. It is resistant to hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide, and potassium hydroxide at room temperature. 2. Avoid strong oxidants. 1, below 70℃ 2. General acid, alkali, and salt solutions. Soft rubber1. It has good elasticity and good wear resistance; 2. It is resistant to the corrosion of general low-concentration acids, alkalis, and salt media, and is not resistant to the corrosion of oxidizing media. 1. Below 70℃; 2. Measure general water, sewage, mud, ore slurryPolytetrafluoroethylene (PTFE) Modified polytetrafluoroethylene (PFA)1. The material with the most stable chemical properties in plastics. It can withstand boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, as well as strong alkalis and various organic solvents; 2. Poor abrasion resistance and adhesion. 1.-40℃~+130℃C(PTFE), -40℃~+160℃(PFA); 2. Strong corrosive media such as acid and alkali; 3. Sanitary media. PO1.
