Kev Taw Qhia Txog Kev Tiv Thaiv Nyiaj Siv Rov Los: Ib qho yuav tsum-Nyeem rau Kev Lag Luam Cov Kws Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Tawm Technology

Silver hu tau dav siv nyob rau hauv ntau yam khoom siv hluav taws xob thiab yog cov khoom siv tseem ceeb ntawm cov hluav taws xob tiv tauj. Hauv cov tshuab xws li hluav taws xob hloov hluav taws xob, relays, thiab cov hluav taws xob hluav taws xob, cov nyiaj hluav taws xob tiv tauj kom ruaj khov tam sim no kev sib kis thiab ntev - lub sij hawm txhim khu kev qha ntawm cov cuab yeej vim lawv cov conductivity zoo heev thiab corrosion kuj. Nrog rau kev hloov khoom dua tshiab, cov nyiaj ntau ntau - muaj cov khoom siv nkag mus rau theem seem, suav nrog ntau hom kev sib tiv tauj xws li Khoom Siv Nyiaj Tiv Thaiv thiab Nyiaj Alloy Contacts. Cov txheej txheem rov ua dua tshiab ntawm cov nyiaj no- muaj cov ntaub ntawv pov tseg tsis yog tsuas yog muaj txiaj ntsig tseem ceeb ntawm kev lag luam tab sis kuj ua tau raws li cov peev txheej rov ua dua tshiab thiab kev ua raws li ib puag ncig, ua rau nws yog txoj hauv kev yooj yim uas cov kws kho mob yuav tsum paub.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cov nyiaj sib tiv tauj feem ntau yog kho rau lub hauv paus hlau los ntawm riveting lossis vuam, xws li Silver Alloy Rivets lossis Silver Solid Contact Rivets. Yuav kom ua tiav kev sib cais zoo ntawm kev sib cuag los ntawm lub hauv paus hlau, siab - kub cua sov nyob rau hauv lub qhov cub ua hauj lwm yuav tsum tau decompose cov nplaum txheej los yog solder, cais cov nyiaj sib cuag los ntawm tooj liab los yog steel puag khoom. Lub hauv paus tseem ceeb ntawm cov kauj ruam no yog nyob rau hauv kev tswj qhov kub thiab txias thiab kev tswj xyuas kev sib cais, ua kom muaj kev sib cuag ncaj ncees thaum tsis txhob muaj nyiaj oxidation thiab poob. Rau kev rov qab los ntawm Pure Silver Contacts thiab Alloy Silver Contacts, qhov zoo ntawm kev sib cais pretreatment ncaj qha txiav txim siab qhov ua tau zoo ntawm cov leaching tom ntej.

 

Tom qab lub cev sib cais, cov concentrated nitric acid feem ntau yog siv los ua tus neeg sawv cev rau kev kho ntub dej. Nyiaj yog oxidized nyob rau hauv lub nitric acid system los tsim ib tug silver nitrate tov. Lub leaching kub yog tswj ntawm 60-80 degree, thiab lub sij hawm tshuaj tiv thaiv yog kwv yees li 2-4 teev. Qhov kub ntau dhau ua rau nitric acid volatilization, thaum kub tsis txaus cuam tshuam rau cov tshuaj tiv thaiv. Tom qab leaching, cov tshuaj yog ntshiab thiab xiav -ntsuab, thiab cov khoom seem yog cais los ntawm lub tshuab nqus tsev pom. Cov theem no yog tsim rau thawj zaug hloov dua siab tshiab thiab enrichment nyiaj los ntawm Silver Contact Points los yog lwm yam nyiaj tiv tauj pov tseg.

 

Txhawm rau txhim kho purity ntxiv, kev lag luam feem ntau siv cov kuab tshuaj extraction rau kev sib cais thiab purification. Txoj kev no yog ua raws li qhov sib txawv ntawm kev faib cov nyiaj ions hauv cov theem sib txawv. Cov theem organic xaiv complexes nyiaj ions nrog impurity hlau, ua tiav kev sib cais zoo. Cov theem ntawm cov organic feem ntau muaj cov extractant, ib co-cov kuab tshuaj, thiab ib qho inert organic hnyav, xws li triisooctylamine ua lub ntsiab extractant, ua ke nrog tert-butanol los txhim kho dispersibility, thiab xylene ua cov kuab tshuaj. Lub pH ntawm lub aqueous theem yog tswj ntawm 0.5 thiab 2.

 

Ob theem yog sib tov nyob rau hauv ib tug 1: 1 piv thiab coj mus rau hauv tag nrho kev sib cuag nyob rau hauv centrifugal co tej yam kev mob, tso nyiaj ions mus migrate los ntawm lub aqueous theem mus rau lub organic theem. Cov kauj ruam no muaj txiaj ntsig zoo hauv kev ntxiv nyiaj ions hauv cov khoom siv khib nyiab thiab yog cov kauj ruam tseem ceeb hauv kev ua kom huv.

 

Tom qab extraction, natural stratification yog tiav los ntawm kev siv qhov sib txawv ntawm qhov sib txawv, nrog rau cov txheej txheej sab sauv yog nyiaj - nplua nuj organic theem thiab cov txheej qis yog theem aqueous. Kev tswj hwm nruj nruj yuav tsum tau ua thaum sib cais kom tsis txhob hla - paug. Tom qab ntawd, cov tshuaj ntsev nyiaj tau los ntawm rov qab - rho tawm lossis hloov pauv ncaj qha thiab tom qab ntawd mus rau theem electrolytic refining. Siv cov khoom siv hluav taws xob ncaj qha tam sim no ntawm lub peev xwm ntawm 0.2-0.5V, nyiaj ions raug txo qis ntawm cathode kom precipitate metallic nyiaj, ua tiav cov khoom purity txog li 99.99%. Cov txheej txheem no muaj feem xyuam rau ntau yam nyiaj hluav taws xob tiv tauj cov khoom pov tseg, ua kom cov nqi rov qab thiab purity thaum tswj ib puag ncig.

 

Zuag qhia tag nrho, tus yuam sij rau nyiaj hu rov qab technology nyob rau hauv peb yam: ua ntej, pretreatment sib cais efficiency; thib ob, meej tswj ntawm leaching thiab extraction tsis; thiab thib peb, muaj peev xwm thiab impurity tswj thaum lub sij hawm electrolysis. Los ntawm kev xaiv cov reagent concentrations, cov tshuaj tiv thaiv kub, thiab lub sij hawm qhov rais, ib tug heev npaum thiab tsawg -emission resource regeneration txoj kev yuav ua tau tiav. Nrog rau qhov kev thov nce ntxiv los ntawm cov tshuab hluav taws xob, cov khoom siv hluav taws xob tshiab, thiab cov khoom siv hluav taws xob siab - kawg, cov txheej txheem rov ua dua tshiab thiab ua kom zoo dua cov cuab yeej ntawm cov nyiaj- muaj cov hluav taws xob tiv tauj yuav dhau los ua qhov tseem ceeb thiab tseem ceeb txuas hauv cov saw hlau.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

- Raws li tus kws tshaj lij kev tsim khoom, pebKhoom Siv Nyiaj, Silver Alloy Contacts, thiab lwm yam nyiaj hluav taws xob tiv tauj yog txhua yam tsim los siv cov khoom siv siab -purity nkauj xwb nyiaj. Peb tsis siv cov nyiaj rov qab los ua cov khoom siv raw, ua kom ruaj khov thiab tswj tau kev coj ua thiab kev ntseeg tau. Rau siab - zoo tiv tauj cov khoom daws teeb meem, thov hu rau peb kom paub meej cov ntaub ntawv.
