Kev npaj ntawm electroplated silver coated fibers rau hluav taws xob cua sov raj
Polyester fibers muaj cov yam ntxwv ntawm lub zog siab, zoo tiv thaiv tshav kub, thiab zoo heev txhua yam khoom. Cov nyiaj hlau muaj qhov zoo xws li kev tiv thaiv qis, kev ua haujlwm zoo heev, thermal conductivity, thiab corrosion kuj, tab sis nws daim ntawv thov dav yog txwv vim tus nqi siab ntawm cov nyiaj ntshiab. Kab lus no siv cov txheej txheem ntawm cov tshuaj siv nyiaj plating txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm
1 Kev sim ib feem
1.1 Reagents thiab raw khoom
Polyester short fiber (PET): tensile strength>800MPa, elongation ntawm tawg =(25 ± 9) feem pua, txoj kab uas hla =(20 ± 4) μ m. Tuam Tshoj Textile tshawb fawb lub koom haum; AgNO3, NH3 · H2O, NaOH, anhydrous ethanol, qabzib, thiab thiourea yog tag nrho cov khoom lag luam muaj kev tshuaj ntsuam xyuas.
1.2 Kev npaj cov nyiaj plated fibers
Siv 2 hli ntev luv txiav PET fibers ua cov khoom siv tseem ceeb, kev kho deg ua ntej yog nqa tawm los tsim cov catalytic active core, ua cov tshuaj siv nyiaj plating yooj yim dua. Cov haujlwm tshwj xeeb yog raws li hauv qab no: tom qab roughening PET fiber ntau nrog NaOH tov ntawm w=0.05, nws yog thawj zaug ntxuav nrog dej deionized, ces qhib thiab rhiab nrog ntsev raws li colloidal palladium. Tom qab ntawd, nws raug ntxuav kom huv si nrog dej deionized thiab muab tso rau hauv cov tshuaj plating rau cov tshuaj siv nyiaj plating. Cov concentration ntawm cov tshuaj plating: 10-14g/L ntawm AgNO3 φ= 0.10 feem pua NH3 · H2O, 13g/L NaOH φ{11}}.05 anhydrous ethanol ; Cov ntsiab lus ntawm kev txo cov tshuaj concentration: 10g/L qabzib, w{14}}.0 × 10-6-5.0 × 10-6 thiourea. Qhov kub ntawm cov tshuaj plating yog tswj ntawm 20-30 degree C, thiab lub sij hawm plating yog li 1 teev. Tom qab plating, ntxuav cov fibers nrog dej deionized thiab nqus kom qhuav ntawm qhov kub thiab txias.
