nickel net yes A sort of Universal Material , Commonly used At Various industry , include Chemical processing , plating and filter . make nickel net in this way Suitable These application of The essential characteristic one yes it were able exist Acidic environment middle resistance corrosion . but this one extraordinary characteristic behind of science principle in the end yes What ?
exist molecular level superior , when Metal surface layer atom or molecular Instead of surroundings interaction hour , use of time , meeting guide To corrosion Phenomenon occur , impressive revel night ! this Once passed Procedure often generate oxide , hydroxide or Salts , and then reduce Material strength , Shocked . especially in Acidic environment middle , Depend on exist Hydrogen ion〔H 〕 exist accelerate Got it this one reaction rate , Acidic Solvent right Metal atom break down effect more Significantly , thereby further Promote Got it corrosion , step and process .
nickel The reason famous exist That exist Acidic environment Down excellence Corrosion resistance , Apart from Everyone All learn of , main benefit exist That atom level superior unique Chemical structure and nature , this include but Not limited to process Stablize oxide protective film ability , electronic structure particularity as well as right specific corrosion medium Affinity difference wait complex mechanism , These factor comprehensive effect , make Nickel material material exist face Acidic environment hour were able Significantly resistance corrosion process , maintain and Keep That physics and Chemistry able stability , Incomparable happiness !
1. passivation : when nickel exposed At oxygen middle time , That surface meeting form layer thin Protective Oxidation layer , this Once passed Procedure called passivation . Should Oxidation layer act as barrier , prevent occur further of corrosion reaction .
2. Chemical stability : nickel relatively inertia , Not easy and most acid occur reaction . This kind of stability make nickel were able Keep That structure integrity and exist longer time Inside resistance corrosion .
3. self-healing performance : if Oxidation layer quilt damage or Remove , nickel have pass form new The protective layer conduct self-healing of ability . This kind of self-healing mechanism helpful long term maintenance Material of Corrosion resistance .
pass and For example chromium or molybdenum wait element process alloy , strong and sturdy . nickel net were able exist specific corrosion environment Down Showing more superior Corrosion resistance able , thereby supply additional protection Effect .
Apart from Corrosion resistance outside , nickel net return have industry application required of other characteristic , include high thermal conductivity and conductivity , Excellent of strength weight Compare as well as good of forming sex . These characteristic make nickel net become from Chemical processing equipment arrive Battery electrode wait widely used of Popularity choose .
In short , nickel net exist Acidic environment middle of Corrosion resistance behind of science principle lies in That form Protective Oxidation layer of ability , That Chemical stability , self-healing characteristic as well as Instead of he element of potential Alloying ability . These characteristic make nickel net become A sort of reliable and durable of Material , Available At have corrosion question of have challenge of industry application .
