Because lignite dryer is long-term to humidity and viscosity all very tall lignite undertakes stoving works, corrode because of what this causes a part extremely easily, of the anticorrosive work that how does good lignite dryer is machine of SBM of manufacturer of mine equipment major? The article is fought with respect to what share lignite dryer together with everybody corrode a method.
One, lignite dryer is electrostatic and pulverous spray law
Law of electrostatic and pulverous spray is the method that a kind of new-style coating Tu Zaihong does machine cylindrical shell. The photograph of liquid state paint that uses with traditional manufacturer is compared, spray law lights electrostatic powder avirulently, safely, not easily to explode easily, its fight use farinaceous coating corrode ability to be able to be rivalled completely with stainless steel photograph.
Electrostatic coating has the characteristic with good of tough, fast, adornment, have be able to bear or endure outdoor outstanding await gender and hear resistance, still have at the same time be able to bear or endure outstandingly industrial dryer is corroded, be able to bear or endure outstanding burnish and pulverization function, shade function, can replace the dryer that use stainless steel makes completely, reduce cost greatly.
2, lignite dryer weld uses austenite nickel chromic stainless steel to undertake soldering
Dryer has a lot of place to must undertake soldering, solder vintagely uses data often appears rupture, corrode wait for a phenomenon, the life influence to dryer and its are serious.
The distinction of austenite nickel chromic stainless steel and common carbon steel depends on thermal conductivity differring, the coefficient of expansion when heating is big, the characteristic with tall resistance. These characteristics restricted this kind of material to must use special type method when solder. The corrosion resistance of this kind of rolled steel is extremely tall, reach its to be caused not easily rupture wait for a circumstance.
3, lignite dryer is relevant the special processing of the component
In the production production of dryer, having very much part is used carbolic steel, if working hours is long when, cause easily in its surface many ferruginous, often want to have the many artificial job that divide rust.
Passivation, phosphor changes a way basically is to pass electricity and electrochemistry reaction, pass one-time processing, can make be born already full ferruginous steely workpiece, the surface presents the original facial expression that gives a metal, build compact antirust film layer in metallic surface at the same time. After using this kind of method, although we put equipment into damp environment to also won't be caused,rust, and this kind of method and its are simple, material resources of OK and many economic labor power, reduce investment, it is to use a most extensive kind of anticorrosive method.
Normally dryer is comprise by flat, cylindrical shell and weldment, the dryer of different position, different utility its are anticorrosive the method also is distinguishing. SBM machine thinks, use a case according to the job of dryer only, the component that is aimed at different position undertakes special processing, ability prolongs the service life of lignite dryer effectively.
The dryer that SBM machine produces includes 3 tubes of lignite dryer, bowl dryer, dryer, sand dryer, slime dryer, scoria dryer, desulphurization dryer to wait, sort is diversiform, model is all ready, the welcome seeks advice from a choose and buy.
