Ultrafine silver hmoov yog cov khoom tseem ceeb hauv kev lag luam hluav taws xob thiab hluav taws xob

Ultrafine silver hmoov yog ib yam khoom tseem ceeb hauv kev lag luam hluav taws xob thiab hluav taws xob, thiab yog cov hmoov hlau siv dav siv hauv kev lag luam hluav taws xob. Vim nws cov qauv tshwj xeeb, cov nyiaj nanoparticles nthuav tawm cov teebmeem me me, cov teebmeem quantum loj, cov teebmeem saum npoo av, thiab cov teebmeem macroscopic quantum tunneling, ua rau lub cev thiab tshuaj lom neeg cov khoom uas cov khoom siv tsis muaj. Nano nyiaj hais ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm qhov chaw ua kom zoo nkauj Raman spectroscopy, txhim kho qhov zoo ntawm resonance scattering spectroscopy, molecular biology, supramolecular systems, thiab yog ib qho ntawm cov ntaub ntawv tseem ceeb rau kev tshawb fawb theoretical.
Silver hmoov nrog micron loj.
Nano sized silver hmoov (nano silver hmoov)
Cov particle morphology suav nrog spherical, dendritic, flaky, cubic, thiab microcrystalline.
Tom qab complexing nyiaj nitrate nrog ammonia dej, ntxiv dispersant, txo nrog hydrazine, ntxuav nrog dej, lim, thiab ziab, cov khoom tau txais.
Qhov nruab nrab particle loj<0.5 μ m. The specific surface area is 0.1-5m2/g.
Tsis tas li ntawd, kuj tseem muaj formaldehyde txo nyiaj oxide txoj kev. Thiab txoj kev hloov nyiaj nitrate rau hauv cov nyiaj carbonate thiab txo nws nrog triethanolamine kom tau cov nyiaj molecular.
Nano silver hmoov muaj qhov ua haujlwm siab ntawm qhov chaw thiab kev ua haujlwm catalytic, thiab tau siv dav los ua cov catalyst thiab diluent rau ultra-tsawg kub tub yees. Nyob rau tib lub sijhawm, vim nws lub cev thiab tshuaj lom neeg tshwj xeeb, nws kuj tau siv dav hauv kev tshuaj xyuas kev tiv thaiv kab mob, kev txhim kho sensor, molecular electronics, thiab lwm yam. Tsis tas li ntawd, ntxiv ib qho me me ntawm nano nyiaj rau cov tshuaj fiber ntau tuaj yeem txhim kho qee yam khoom ntawm cov khoom siv tshuaj fiber ntau thiab ua rau lawv muaj peev xwm bactericidal. Ultrafine nyiaj hmoov tuaj yeem raug faib ua cov duab kheej kheej, flocculent, dendritic, thiab flaky raws li nws cov morphology; Raws li particle loj, nws tuaj yeem muab faib ua: hmoov zoo hmoov, nrog qhov nruab nrab particle loj ntawm 10-40 μ m; Cov hmoov zoo heev nrog qhov nruab nrab particle loj ntawm 0.5-10 μ m; Ultrafine silver hmoov, nruab nrab particle loj<0.5 μ m; Nano silver powder, particle size<0.1 μ m.
Cov txheej txheem kev npaj ntawm ultrafine nyiaj hmoov feem ntau suav nrog cov txheej txheem roj, cov txheej txheem ua kua theem, thiab cov txheej txheem txheej txheem. Gas theem txoj kev muaj peev txheej siab, kev siv hluav taws xob siab, thiab tsis muaj txiaj ntsig; Lub ultrafine silver hmoov npaj los ntawm cov txheej txheem solid-state muaj ib tug loj particle loj thiab ib tug dav particle loj tis ntau yam; Txoj kev ua kua theem tshuaj txo qis tam sim no yog ib txoj hauv kev siv rau cov nqi qis thiab me me ntawm ultrafine silver hmoov.
Lub hauv paus ntsiab lus ntawm kev npaj ultrafine nyiaj hmoov los ntawm cov kua-theem tshuaj txo txoj kev yog siv ib tug txo tus neeg sawv cev rau deposit nyiaj nyob rau hauv hmoov daim ntawv los ntawm nws cov ntsev los yog complex aqueous tov los yog organic system. Feem ntau siv cov tshuaj txo qis xws li formaldehyde, ascorbic acid, glycerol, organic amines, unsaturated alcohols, sodium citrate, hydrazine, thiab hydrazine compounds. Hydrazine hydrate feem ntau yog siv. Los ntawm kev ntxiv ib qho nyiaj ntawm nitrate raws li ib qho ntxiv rau cov nyiaj ammonia aqueous tov thiab kho tus nqi ntawm cov additive nyob rau hauv qhov kev txiav txim ntawm txo tus neeg sawv cev hydrazine hydrate, sib txawv particle ntau thiab tsawg ntawm cov hmoov hmoov yuav tau. Cov nitrate additives siv tuaj yeem yog ib lossis ob, thiab cov nyiaj ntxiv nyob ntawm qhov yuav tsum tau ua. Cov hmoov nyiaj tau los ntawm txoj kev no muaj qhov me me me me, me me particle loj faib ntau yam, thiab zoo rov ua dua tshiab.
