Dab tsi zoo dua, tooj dag lossis npib tsib xee

1. Dab tsi yog qhov zoo dua, tooj dag lossis npib tsib xee?

Qhov kev xaiv ntawm tooj dag thiab npib tsib xee nyob ntawm daim ntawv thov tshwj xeeb, raws li txhua cov khoom muaj cov khoom sib txawv uas ua rau nws zoo dua hauv qee cov ntsiab lus. Ntawm no yog cov ncauj lus piav qhia:

Kev sib xyaw & cov hauv paus:

Tooj liab yog ib qho alloy ntawm tooj liab thiab zinc (feem ntau 55-95% tooj liab, nrog zinc thiab qee zaum cov kev txhuas me me, tin, lossis txhuas).

Nickel yog hlau ntshiab (tshuaj lom neeg ni) lossis, feem ntau hauv cov ntawv thov, ib feem ntawm alloys (piv txwv li, ntawm cov neeg siv npib tsib xee, cuponickel).

Lub zog & Hardness:

Brass muaj lub zog nruab nrab (tensile muaj zog Nws yog malleable thiab tuaj yeem yooj yim machined lossis tsim.

Pury Nickel yog cov mos mos (tensile lub zog ~ 345 mpa Nickel alloys Excel nyob rau hauv high-kub lub zog, tuav tseg hardness txawm nyob ntawm 600-1,000 degree.

Corrosion Kuj:

Brass tiv thaiv corrosion nyob rau hauv me me ib puag ncig (piv txwv li, dej) tab sis muaj peev xwm ua kua rau hauv zinc) hauv cov kua dej khov (piv txwv li, ntsev lossis kua qaub).

Ntshiab Nickel thiab Nickel alloys muaj kev daws teeb meem zoo dua, tshwj xeeb hauv cov kev daws teeb meem alkalwater, thiab kub nyiam cov tshuaj ntsuab ib puag ncig. Lawv feem ntau siv hauv kev ua lag luam lossis cov ntawv thov marine.

Aesthetics & conductivity:

Brass muaj qhov sov sov, kub hulim, ua rau nws nrov rau cov khoom zoo nkauj, cov hniav nyiaj hniav kub, lossis seev suab paj nruag. Nws yog ib tug neeg saib xyuas zoo ntawm cov cua sov thiab hluav taws xob (ho tsawg dua li tooj liab).

Nickel muaj qhov ci ci, silvery tiav uas tiv taus tarnishing, ua rau nws zoo tagnrho rau kev plating (piv txwv li ntawm cov khoom siv tawv, ntawm cov khoom siv ruaj khov, ci ntsa iab. Nws kuj yog tus neeg coj ua zoo tab sis tsis muaj txiaj ntsig tsawg dua tooj dag rau kev siv hluav taws xob.

Tus nqi:

Tooj liab yog feem ntau pheej yig dua li npib tsib xee, raws li npib tsib xee yog cov khoom kim dua. Qhov no ua rau brass zoo dua rau cov ntawv thov nqi zoo li cov kav dej khov kho lossis cov khoom siv tsawg.

Tooj dag yog qhov zoo dua rau cov khoom dai kom zoo nkauj, tus nqi qis, lossis cov ntawv thov siv khoom lag luam corrosion tsis kam thiab ua haujlwm. Npib tsib xee (lossis nickel alloys) yog zoo dua rau cov kev kub kub, muaj zog lossis muaj cov neeg ruaj khov, zoo li rau cov ua tiav ruaj khov, tarnish-resistant first.

2. Qhov twg tooj liab-Nickel siv?

Tooj liab-tsibckel (cuponickel) alloys, compued feem ntau ntawm cov tooj hlau (60-90%) thiab zinc, muaj txiaj ntsig (10-40%) thiab zinc, lub zog, thiab cov tshuaj tiv thaiv kab mob antimicrobial. Cov ntawv thov tseem ceeb muaj xws li:

Marine engineering:

Hull cladding thiab piping rau cov nkoj, subsharines, thiab cov pa hluav taws xob. Lawv txoj kev tawm tsam rau ntsev ntsev (suav nrog pitting thiab biofouling) ua rau lawv zoo tshaj rau cov kav dej hiav txwv, kev hloov pauv cua sov, thiab cov ntaub ntawv cua sov, thiab cov ntaub ntawv cua sov, thiab cov ntaub ntawv cua sov, thiab cov ntaub ntawv cua sov.

Desalination Nroj Tsuag:

Siv hauv tubing thiab cov khoom siv rau cov khoom siv desalination, qhov twg tsis kam rau cov dej brackish thiab brine corrosion yog qhov tseem ceeb.

Nyiaj npib:

Ntau npib thoob ntiaj teb (piv txwv li, Asmeskas npib tsib xee, European 50-cent npib) yog tsim los ntawm cupronickel (feem ntau 75% tooj liab, 25% tooj liab, 25% tooj). Nws yog ruaj, tiv taus hnav, thiab muaj qhov sib txawv ntawm silvery tsos.

Hluav Taws Xob Thiab Cov Kev Siv Thermal:

Cov chaw tsheb npav, cov txuas, thiab cov khoom cua sov, zoo li cupronickel muaj cov tooj hluav taws xob zoo) ua ke nrog lub zog loj dua thiab corrosion tsis kam.

Cov Khoom Siv Kho Mob:

Qee cov twj phais thiab cov neeg siv tshuaj thiab kev siv neeg siv CUPRONICICEL vim nws biocompatibility thiab tsis kam mus rau lub cev nqaij.

Cov Hluav Taws Xob Tshav Kub Kub:

Siv nyob rau hauv cov kev sib pauv cua sov, tshwj xeeb yog cov kev siv cov dej ua kua lossis dej hiav txwv, vim lawv thermal conductivity thiab corrosion tsis kam.

3. Yuav ua li cas ua Nickel plating ci

Nickel plating, paub txog nws ci, silvery tiav, tuaj yeem poob nws cov lus hais txog lub sijhawm vim yog tarnish, oxidation, lossis cov khoom qias neeg. Rov qab nws lub teeb ci nrog kev ntxuav, polishing, thiab tiv thaiv cov nplaim dej. Ntawm no yog ib qib zuj zus ntawm-kauj ruam qhia:

1. Huv si:

Tshem tawm cov av saum npoo av, roj, lossis txiv av siv tshuaj ntxuav me me lossis xab npum sib xyaw nrog dej sov. Maj mam txhuam nrog daim ntaub mos muag lossis daim txhuam cev (zam cov ntaub qhwv tsis zoo, uas tuaj yeem khawb lub npib tsib).

Rau cov tawv nqaij tawv (piv txwv li, cov ntxhia pob zeb hauv av lossis dej huv (1: 1: 1: WIS Thov nrog daim ntaub mos muag, cia nws zaum rau 5-10 feeb, tom qab ntawd so huv.

2. Polish kom rov qab ci:

Siv hlau hlau Polish tsim rau npib tsib xee (piv txwv li, flitz hlau Polish, Simichrome). Thov ib qho me me rau daim ntaub mos muag muag, microfiber ua haujlwm tau zoo) thiab tshiav hauv cov suab nrov nrog lub teeb taub hau.

Rau cov chaw loj heev, rov ua tus txheej txheem kom txog thaum ci tau rov qab los. Zam kev sib txhuam sib txhuam, ua kev txhuam hniav ntau dhau tuaj yeem hnav cov plating dhau sijhawm.

3. Tshem tawm stubborn tarnish:

Rau oxidation lossis tsaus me ntsis, tsim cov tshuaj txhuam ntawm ci dej qab zib thiab dej (3: 1 piv). Thov rau thaj chaw turnished, cia nws zaum rau 10-15 feeb, ces maj mam buff nrog daim ntaub mos muag. Yaug kom huv si nrog dej.

Rau cov mob hnyav dua, siv qhov kev daws teeb meem dolrochloric did (muriatic acid) dilution: thiab yaug kev tiv thaiv tam sim ntawd tom qab 10-15 vib nas this kom tsis txhob ua rau lub plating puas tsuaj.

4. Tiv thaiv qhov ua tiav:

Tom qab tu thiab ua polishing, thov ib txheej nyias ntawm Carnauba ciab lossis tus siv nyiaj txiag hlau lossis kev tiv thaiv tus neeg npib ob los ntawm yav tom ntej tinnish thiab oxidation. Buff maj mam nrog daim ntaub huv huv los txhim kho kom muaj ci.

Zam tsis txhob muaj tshuaj harsh (piv txwv li, tshuaj dawb, ammmia) lossis lub caij noo noo, vim tias cov no tuaj yeem npub ua tiav.

Yog hais tias tus npib npib tsib xee yog chipped, tawg, lossis hnav los ntawm lub hauv paus hlau, polishing tej zaum yuav tsis tag nrho nws cov tsos. Nyob rau hauv cov xwm txheej zoo li no, rov plating yuav tsim nyog rau ib qho kev sib hnav, ci iab tiav.
