Puas yuav Brass Screws Rust?

Ib lo lus nug tseem ceeb rau leej twg xaiv cov fasteners yog: "Yuav ua li cas tooj dag screws xeb?" Cov lus teb luv luv yogtsis muaj- tooj dag screws yuav tsis xeb-tab sis qhov yooj yim no npog qhov tseem ceeb nuances. Xeb yog tshwj xeeb rau hlau-raws li cov hlau (xws li steel, carbon hlau), tsim thaum hlau reacts nrog oxygen thiab ya raws. Brass, alloy ntawm tooj liab (60-70%) thiab zinc (30-40%), tsis muaj hlau{10}} yog li xeb tsis tuaj yeem. Txawm li cas los xij, tooj dag tuaj yeem raug "oxidation" (tarnishing lossis patina tsim) hauv qhov chaw hnyav, uas cuam tshuam rau cov tsos tab sis tsis tshua muaj kev cuam tshuam kev ua haujlwm. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau kev xaiv cov fasteners uas sawv qhov kev sim ntawm lub sijhawm.

Rau ntau tshaj 15 xyoo,JOYEAR Hlau ua haujlwmtau leveraged tooj dag lub corrosion kuj kom xa cov kev daws teeb meem rau kev lag luam, hluav taws xob, thiab kev siv dej hiav txwv.

Lawv cov khoom lineup-xws li tooj liab alloy precision stamping qhov chaw, SS304 nruam hinges, thiab kev cai tooj dag fabrications{13}} ntxiv dag zog rau cov kav, txawm nyob rau hauv ib puag ncig corrosive.

Hauv phau ntawv qhia no, peb yuav piav qhia tias yog vim li cas tooj dag screws tsis xeb, tshawb xyuas seb lawv ua li cas corrode (thiab thaum nws tseem ceeb), thiab qhia tias JOYEAR qhov kev txawj ntse ua kom cov tooj dag lub neej ntev npaum li cas. Thaum kawg, koj yuav paub meej yuav ua li cas tiv thaiv tooj dag screws los ntawm oxidation-thiab vim li cas kev koom tes nrog JOYEAR ua kom ntev - kav ntev, xeb- ua haujlwm dawb.

1. Vim li cas tooj dag Screws tsis tuaj yeem xeb: Kev Tshawb Fawb ntawm Corrosion

Txhawm rau teb "Yuav ua li cas tooj dag tuaj yeem xeb?", peb thawj zaug txhais cov xeb thiab sib piv nrog tooj dag cov tshuaj pleev xim:

1.1 Rust yog dab tsi?

xeb (hlau oxide, Fe₂O₃) tsim tshwj xeeb thaum hlau los yog hlau-raws li alloys (steel, cam khwb cia hlau) hnov ​​​​mob nrog oxygen thiab noo noo. Cov tshuaj tiv thaiv ua rau cov hlau tawg, tsim flaky, liab -xim av corrosion uas ua rau cov khoom tsis muaj zog dhau sijhawm. Yog tsis muaj hlau, xeb tsis tuaj yeem tsim.

1.2 Brass's Composition: Tsis muaj Hlau=Tsis muaj xeb

Brass yog non{0}}ferrous alloy (tsis muaj hlau) ua los ntawm tooj liab thiab zinc feem ntau:

1. Copper (Cu)60-70% ntawm cov alloy, muab corrosion kuj thiab conductivity.
2. Zinc (Zn): 30-40% ntawm cov alloy, txhim khu lub zog thiab machinability.
3. Yeem yeem Additives: Manganese, tin, los yog lead (xws li, naval tooj dag ntxiv tin rau ntxiv marine corrosion kuj).

Cov hlau no -dawb muaj pes tsawg leeg yog vim li cas tooj dag screws yeej tsis xeb-txawm tias nyob rau hauv ib puag ncig ntub lossis ntub.JOYEAR tus tooj liab alloy precision stamping qhov chawqhia qhov zoo no, raws li lawv tau tsim los ntawm tooj dag- tau tshaj tooj liab-zinc alloys, kom tsis txhob muaj xeb nyob rau hauv tandem nrog tooj dag screws.
