Peb siv ntau cov hlau hauv peb lub neej, thiab muaj cov hlau hauv ntau yam khoom.Dawb tooj liabyog tooj liab-raws li alloy nrog nickel ua lub ntsiab ntxiv.Nws yog nyiaj-dawb thiab muaj xim hlau luster, yog li nws yog hu ua cupronickel.tooj liab thiab npib tsib xee tuaj yeem ua rau tsis muaj kev sib tawg nyob rau hauv ib leeg, yog li tsim cov kev daws teeb meem txuas ntxiv, uas yog, tsis hais qhov sib piv ntawm ib leeg, nws yog ib qho α-ib-theem alloy.Thaum npib tsib xee melted rau hauv liab tooj liab thiab cov ntsiab lus ntau tshaj 16%, cov xim ntawm lub resulting alloy ua dawb li nyiaj.Qhov siab dua cov ntsiab lus nickel, cov xim dawb.Cov ntsiab lus nickel hauv cupronickel feem ntau yog 25%.
1. Lub ntsiab siv ntawm cupronickel
Ntawm cov tooj liab alloys, cupronickel yog dav siv nyob rau hauv shipbuilding, roj av, tshuaj lom neeg kev lag luam, kev tsim kho, hluav taws xob fais fab, precision instrumentation, cov cuab yeej kho mob, suab paj nruag ntau lawm thiab lwm yam sectors raws li corrosion-resistant structural qhov chaw vim nws zoo heev corrosion kuj thiab yooj yim molding, ua thiab vuam..Qee cov cupronickel kuj muaj cov khoom siv hluav taws xob tshwj xeeb, uas tuaj yeem siv los ua cov khoom tiv thaiv, cov khoom siv thermocouple thiab cov nyiaj them nyiaj.Tsis yog-kev lag luam cupronickel feem ntau yog siv los ua cov khoom siv dai kom zoo nkauj.
Qhov thib ob, paub qhov txawv ntawm cov tooj liab dawb thiab nyiaj
Vim hais tias dawb tooj liab hniav nyiaj hniav kub zoo ib yam li sterling nyiaj hniav nyiaj hniav kub nyob rau hauv cov nqe lus ntawm cov xim thiab workmanship.Qee cov tub lag luam uas tsis ncaj ncees coj kom zoo dua ntawm cov neeg siv khoom 'tsis muaj kev nkag siab ntawm cov hniav nyiaj hniav kub thiab muag cov hniav nyiaj hniav kub cupronickel li sterling nyiaj hniav nyiaj hniav kub, thiaj li ua kom tau nyiaj ntau los ntawm nws.Yog li, yuav ua li cas paub qhov txawv ntawm cov nyiaj sterling nyiaj lossis cov hniav nyiaj hniav kub dawb?
Nws tau nkag siab tias cov hniav nyiaj hniav kub sterling nyiaj yuav raug cim nrog cov lus S925, S990, XX cov nyiaj ntshiab, thiab lwm yam, thaum lub cupronickel hniav nyiaj hniav kub tsis muaj cov cim zoo li no lossis cov cim tsis meej heev;qhov saum npoo ntawm cov nyiaj tuaj yeem raug cim nrog rab koob;thiab tooj liab kev ntxhib los mos yog tawv thiab tsis Nws yog ib qho yooj yim mus khawb caws pliav;Cov xim ntawm cov nyiaj yog me ntsis yellowish silver-dawb, uas yog vim hais tias cov nyiaj yog yooj yim rau oxidize, thiab nws tshwm tsaus daj tom qab oxidation, thaum cov xim ntawm dawb tooj liab yog dawb huv, thiab ntsuab me ntsis yuav tshwm tom qab ib lub sij hawm.
Tsis tas li ntawd, yog hais tias ib tug poob ntawm concentrated hydrochloric acid poob rau hauv cov nyiaj hniav nyiaj hniav kub, ib tug dawb moss-zoo li precipitate ntawm silver chloride yuav raug tsim tam sim ntawd, uas tsis yog nrog cupronickel.
Tsab ntawv xov xwm no qhia meej txog qhov tseem ceeb ntawm kev siv cupronickel thiab kev txheeb xyuas tus kheej ntawm cupronickel thiab nyiaj.Cupronickel yog siv nyob rau hauv shipbuilding, roj av, tshuaj lom neeg kev lag luam, kev tsim kho, hluav taws xob fais fab, precision instruments, cov cuab yeej kho mob, suab paj nruag ntau lawm thiab lwm yam departments raws li corrosion-resistant yam ntxwv qhov chaw.Dawb tooj liab tsis yooj yim rau khawb, thiab xim yog dawb huv, uas txawv heev ntawm nyiaj.
