How to treat foam nickel before use

img Foam nickel use forward how deal with
face attack , were able withstand attack , slow down right Body of impact , can only achieve Protect Personal safety of Effect . However , scholar them Discover Got it A sort of new type bulletproof Material—— Foam Metal composite materials ( CMFs ) , it not only able resistance attack , return able destroy attack . Foam Metal composite materials return Can efficient block X-ray , gamma rays and neutron Rays , That refractory heat resistance able yes pure gold genus of double . This kind of new Material of application yes Depend on USA North Carolina stand University mechanical and Aeronautical Engineering Tie professorAfsaneh Rabiei develop of . It is reported that , exist experiment middle , experimenter Will one caliber for0.3 inch of7.62×63 mmM2 ordinary bullet shoot towards ahead of Foam Metal composite materials , and this Once passed Procedure yes according to nation bulletproof graduate School promulgate of bulletproof test standard program conduct of . USA National Institutes of Health ( NIJ ) , so data At once enough Got it . shoot towards Foam Metal composite materials hour nickel content : ≥99.9% ; product name : other brand : ni99.99 ; Origin : Shanghai weight : 1kg/ pieces ; Impurities content : 0.1% ; brand : sponge nickel net ; Foam nickel Filter ; High temperature resistance Foam nickel Specification : custom made Aperture : 130ppi thickness : 0.5-40mm Aperture : 0.1-10mm Porosity : 60-98% ; Through hole Rate : ≥98 ; accumulation density : >0.1g/cm3 ; Every inch length pores number : 5-130 indivual ; big geometry size : 600×600mm , Can according to Require custom made tensile strength : 8-50mpa Compressive strength : ≥250kPa ( compression to50% pressure value ) mechanical strength : >2-7mpa High temperature resistance : ≥500℃ Heat transfer coefficient : >3W/(m2k) Foam nickel filter characteristic : 1 , nickel content exist99% above , the remaining for A small amount carbon and Chemical sediment . 2 , filter Accuracy : at present us ofPPI exist5-130PPI between , filter Accuracy exist5mm-200um between . accumulation density only nickel of one fifth , specific surface product very big , still Keep Got it nickel good of physics and Chemistry able . therefore , new structure of Excellent characteristic make That become A sort of Application areas relatively widely of new type Function Material . For example exist Chemical power supply field , application At NiMH , nickel* , The fuel cell wait , Foam nickel type Positive and negative poles make Battery performance Double improve . Foam nickel carbon complex electrode Material yes lithium battery of ideal Material . Should Rechargeable Battery widely used At cell phone , computer , electric Scooter , electric bike , mix power car , electric toys car , Cordless electrical tools , electronic digital product wait . exist Chemical industry field Available do catalyst and carrier , filter medium , Splitter Inside medium ( like Oil and water Splitter , Oil and gas separation device , Automobile exhaust filter , Air purification device , electronic cigarette , range hood wait ) . because That specific surface product big , Can reduce Energy consumption , Improve efficiency . exist electrochemistry project field—— used for electrolysis Hydrogen production , Electrocatalysis Craftsmanship , electrochemistry metallurgy wait . exist thermal energy project field , not only Can as heat conduction Material , return Can as Efficient heat conduction“ core” “ Heat pipe” Material Can Double Improve efficiency . main Features : Super light quality : ** specific surface product , proportion0.2~0.3 , yes water of1/4 , wood of1/3 , Metal aluminum of1/10 , iron of1/30 , Super light . 2 , Sound absorption : porous structure have Broadband Sound absorption of Features . 3 , electronic Wave shield : pass compare Thin of thickness shield about90dB of electronic Wave . 4 , Processability able : Can cutting , bending , Simple Paste . 5 , fire resistance : Keep shape Stablize , high temperature Down Not easy combustion , High temperature resistance . 6 , Recycle use : Metal scrap recyclable use . 7 , thermal conductivity : Porous Material have very powerful of thermal conductivity . 8 , Breathable : all quality of three dimensional Network structure have filter Function , gas , liquid of flow stability Excellent . 9 , Sound insulation : pass additional processing Reachable arrive compare high of Sound insulation Effect . product specifications and Technical Parameters : project parameter scope Number of holes ( PPI ) 13~120 ( ±5~10 ) Areal density ( g/㎡ ) 280~3000 (±30~200) thickness(mm) 0.5~10 (±0.05~1.0) long/ Width size(mm) 70≤ long/ Width≤500(±0.5) , yes family dedicated to R&D , Production , Sale for One body of major high tech company high quality Porous Metal Function Material of R&D and manufacture . yes domestic Foam nickel and he Porous Foam made from metal of important manufacturer one . company main product as follows : 1 , continuous Foam nickel : application At high performance Environmental friendly NiMH batteries of Production manufacture . Autonomy R&D Production of high performance continuous Foam nickel Can satisfy power NiMH batteries of need . 2 , Special Porous Metal : nickel , copper , iron and complex , used for Special filter carrier , catalytic carrier , electromagnetic shield , sound absorbing material , precious metals Convert and Recycle
