Four core advantages of titanium stirrer for reactor: corrosion resistance, weight loss and long life

reaction kettletitanium stirrerStrong corrosion resistance, light weight, Long service life, Low maintenance costs Four core advantages, widely used in chemical, hydrometallurgy, Electroplating and other industries.dilute sulphuric acid, hydrochloric acid, Chloride such strong corrosive medium conditions, Ordinary stainless steel mixers often need to be shut down and replaced after 3 to 6 months, moreovertitanium stirrerThe stable service life can reach 5-15 years.This article combines Baoji titanium valley titanium material project actual combat experience, detailed analysistitanium stirrerThe advantages and brand selection points.

Titanium placed in oxidizing, neutral and weakly reducing media, A dense titanium dioxide oxide protective film is spontaneously formed on the surface, This passivation film has the ability to repair itself., and is also the fundamental reason for the excellent corrosion resistance of titanium materials. under different corrosive mediatitanium stirrerThe performance difference is obvious: dilute sulfuric acid condition with concentration ≤10%, TA2 puretitanium stirrerAvailable for 5-8 years, the service life of TA10 titanium added with palladium element can reach 10-15 years;For hydrochloric acid conditions with concentration ≤5%, TA10 is preferred, and TA2 is not recommended for use in this environment;Titanium is the preferred material for chloride systems such as brine, seawater and wet chlorine.Hydrometallurgical electrolysis, plating solution system, titanium material can effectively resist pitting and crevice corrosion.

Titanium density is only 4.51g/cm³, about 56% of carbon steel, stainless steel density.The overall weight of titanium is nearly half that of stainless steel for mixers of the same structure specifications.Lightweight features bring three engineering values, Reduce the operating load of the mixing shaft, Support for longer stirring shafts, lar blade designReduce motor load and save energy by 10%-20%;Equipment weight is lower, on-site disassembly, maintenance operations more convenient.

Chemical reactor conditions, different brandstitanium stirrerTypical service life: TA2 Industrial puretitanium stirrer 5-8 year;TA10 contains palladiumtitanium stirrer 10-15 years;TC4 titanium alloy stirrer has higher strength and service life of 8-12 years. Core principles of long life, Once the passivation film on the titanium surface is damaged, it can repair itself, Unlike stainless steel equipment, corrosion resistance is maintained by corrosion protection or cathodic protection., Reduce the risk of failure due to coating shedding.

titanium stirrerIt belongs to low maintenance equipment and can basically realize maintenance-free operation.No need to apply corrosion protection coating regularly, No matching cathodic protection device, Spare parts replacement frequency is low, The maintenance cycle generally exceeds 5 years. althoughtitanium stirrerThe initial purchase input is 3-5 times that of stainless steel mixer, However, the full cycle accounting is extended by 5 to 10 years, comprehensive procurement, the result in downtime, Total cost of repair and replacement, Instead, it can be reduced by 30 - 50%.

Titanium grades can be selected according to field medium conditions, dilute sulphuric acid, chloride media, TA2 meets common needs, TA10 for durabilityFor hydrochloric acid corrosion conditions, TA10 must be selected;TC4 titanium alloy is selected for severe working conditions of high temperature superimposed corrosion;TA1 high purity titanium is recommended for clean production scenarios of food and medicine.
