Lining material | main performance | Temperature | Media comparison |
Natural rubber (soft rubber) | Good elasticity, wear resistance and breaking force;
Resistant to general weak acid, weak alkali corrosion, hydrochloric acid, acetic acid, oxalic acid under high temperature.
| 80℃~90℃ | Measuring water and sewage |
Acid resistant rubber (hard rubber) | Ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide corrosion, but not resistant to oxidant corrosion | -25~+90℃ | Test general acid, alkali and salt solutions |
Neoprene | 1. Excellent elasticity, high breaking force and good wear resistance. 2. It is resistant to the corrosion of low concentration acid and alkali and salt solution, but it is not resistant to the corrosion of oxidizing medium. | <80℃ | Measuring water, sewage, mud and ore pulp |
polyurethane rubber | | <40℃ | Measuring neutral and strongly worn coal slurry, mud and pulp |
Polytetrafluoroethylene | Boiling resistant hydrochloric acid, sulfuric acid, nitric acid, aqua regia, concentrated alkali and various organic solvents;
Good wear resistance and poor adhesion.
| 80℃~180℃ | Measuring concentrated acid, concentrated alkali, strong corrosive solution and sanitary medium |
Silicone fluororubber | 1, excellent elasticity, high breaking force, resistance to low concentrations of acid, alkali and salt in general. | 70℃~250℃ | Measuring water, sewage, steam and sanitary media |
