Rust yog ib qho ntawm feem ntau ua rau fastener sib koom tsis ua hauj lwm nyob rau hauv sab nraum zoov, marine, thiab industrial cheeb tsam. Thaum cov tshuab ntxhua khaub ncaws corrode, lawv poob kev ncaj ncees, txo cov clamping quab yuam, thiab tuaj yeem ntes cov hlua khi rau hauv qhov chaw - ua rau kev saib xyuas qeeb, raug nqi, thiab tsis muaj kev nyab xeeb. Rau cov kws tsim khoom, pab pawg muag khoom, thiab cov kws saib xyuas cov kws tshaj lij qhia cov khoom siv rau cov kab mob corrosive, ib lo lus nug yog lub hauv paus: hom ntxhua khaub ncaws yuav tsis xeb?
Cov tshuab ntxhua khaub ncaws uas muaj xeb- pov thawj yog tsim los ntawm cov hlau tsis yog- cov hlau tsis muaj hlau lossis cov hlau tsis muaj hlau uas tsis muaj hlau nyob rau hauv daim ntawv uas oxidizes rau pom liab xeb. Feem ntau xeb-cov ntaub ntawv siv ntxhua khaub ncaws uas tiv taus yogstainless hlau (tshwj xeeb tshaj yog marine -qib 316 stainless), tooj dag, tooj liab, thiabtooj liab. Rau kev raug mob sab nraum zoov me me, coated steel ntxhua khaub ncaws xws li kub-dip galvanized variants muaj kev tiv thaiv corrosion zoo, txawm tias lawv tsis yog xeb tiag tiag - pov thawj yog tias cov txheej puas.
Xaiv cov xeb kom raug- pov thawj cov ntaub ntawv pov thawj yog qhov tseem ceeb rau kev sib koom ua ke ntev, kev nyab xeeb, thiab tag nrho cov nqi ntawm cov tswv cuab - tshwj xeeb tshaj yog rau cov khoom siv raug dej ntsev, cov pa taws, cov av noo, lossis kev caij tsheb kauj vab ntau zaus. Hauv phau ntawv qhia dav dav no, peb rhuav tshem sab saum toj uas tsis yog -rusting washer hom, piv lawv cov kev ua tau zoo corrosion thiab txhua yam khoom, qhia txog cov txheej txheem xaiv tseem ceeb, thiab piav qhia yuav ua li casprecision hlau fabricationua kom zoo ib yam, ntev -tuaj yeem tiv thaiv corrosion rau cov khoom sib dhos.
Vim li cas qee cov ntxhua khaub ncaws xeb thiab lwm tus tsis ua?
xeb yog lub npe nrov rau hlau oxide, uas tsim thaum hlau los yog carbon hlau raug oxygen thiab ya raws lub sij hawm. Rau lub tshuab ntxhua khaub ncaws kom xeb tiag tiag- pov thawj, nws yuav tsum tsis muaj hlau tsis muaj hlau, lossis tsim cov txheej txheem oxide ruaj khov uas tiv thaiv kev xeb ntxiv los ntawm kev ncav cuag cov khoom siv hauv paus.
Cov hlau tsis yog-ferrous xws li tooj liab, tooj dag, thiab tooj liab tsis muaj hlau, yog li lawv tsis tuaj yeem tsim cov hlau xeb. Cov hlau tsis muaj hlau muaj hlau, tab sis nws cov ntsiab lus chromium siab ua rau nyias, tus kheej - kho chromium oxide passivation txheej ntawm qhov chaw uas thaiv cov pa thiab ya raws los ntawm kev ncav cuag hlau hauv qab. Ntev npaum li cov txheej txheem passivation tseem nyob ruaj khov, stainless hlau yuav tsis xeb.

Yuav Ua Li Cas Xaiv Txoj Cai Rust - Pov Thawj Washer
Xaiv qhov zoo tshaj plaws uas tsis yog -rusting washer nyob ntawm plaub yam tseem ceeb:
- Qhov hnyav ntawm corrosive ib puag ncig: Rau dej ntsev, ntug hiav txwv dej, los yog tshuaj lom neeg, xaiv 316 stainless los yog tooj liab. Rau kev siv sab nraum zoov, 304 stainless yog txaus thiab tus nqi ntau dua - zoo. Rau qhov chaw qhuav hauv tsev, plated steel yuav tsim nyog.
- Load thiab lub zog xav tau: Tsis yog- cov ntaub ntawv ferrous xws li tooj dag thiab tooj liab muaj zog tensile thiab shear zog dua hlau. Rau cov khoom siv hnyav, siv cov hlau tsis muaj hlau lossis tooj liab ntxhua khaub ncaws es tsis yog tooj liab lossis tooj dag.
- Hluav taws xob thiab thermal xav tau: Rau grounding, conductivity, los yog kub hloov daim ntaub ntawv,tooj liab los yog tooj dag washersyeej yog qhov kev xaiv zoo tshaj plaws.
- Kev tswj hwm thiab kev nyiam huv: Rau kev ua zaub mov, tshuaj, thiab khoom siv kho mob, 304 lossis 316 stainless hlau yuav tsum tau ua kom yooj yim tu thiab corrosion kuj.
Lus Cim Tseem Ceeb: Tsis txhob Galvanic Corrosion
Txawm hais tias lub tshuab ntxhua khaub ncaws nws tus kheej tsis xeb, ua ke nrog cov hlau tsis sib xws tuaj yeem ua rau galvanic corrosion ntawm cov khoom tsis zoo. Ib txwm phim cov khoom siv ntxhua khaub ncaws rau cov khoom siv fastener thiab cov ntaub ntawv hauv qab kom ze li sai tau, los yog siv cov khoom sib cais los tiv thaiv kev sib cuag ntawm cov hlau tsis sib xws.
Precision Corrosion-Resistant Washers rau Kev Txhim Kho Kev Ua Haujlwm Zoo
Cov ntaub ntawv zoo ib yam, huv si stamping, thiab nruj me ntsis kam rau ua yog qhov tseem ceeb rau xeb- cov ntaub ntawv pov thawj kom ua tau raws li qhov xav tau. Tsis zoo stamped washers nrog burrs, defects deg, los yog inconsistent cov ntaub ntawv muaj pes tsawg leeg yuav ua tsis tau ntxov ntxov nyob rau hauv corrosive ib puag ncig. Sourcing washers los ntawm precision hlau fabrication koom tes nrog nruj cov ntaub ntawv pov thawj thiab kev tswj kom zoo kom lub sij hawm ntev -, txhim khu kev qha corrosion kuj.

Cov lus nug nquag
Q: Puas yuav stainless hlau ntxhua khaub ncaws puas xeb?
- A: Raws li ib txwm muaj, tsis muaj - stainless hlau ua tus kheej - kho chromium oxide txheej uas tiv thaiv xeb. Txawm li cas los xij, nyob rau hauv qhov chaw siab heev -chloride ib puag ncig xws li dej ntsev ncaj qha rau hauv dej, txawm tias 316 stainless tuaj yeem ntsib pitting corrosion yog tias txheej txheej passivation dhau los. Rau feem ntau siv sab nraum zoov thiab kev lag luam,stainless hlau washersyog xeb- pov thawj zoo.
Q: Puas yog galvanized washers xeb- pov thawj?
- A: Tsis yog. Galvanized washers muaj zinc txheej uas ua rau xeb qeeb, tab sis yog tias cov txheej yog khawb los yog hnav los ntawm, cov hlau hauv qab yuav xeb. Lawv muaj kev tiv thaiv corrosion zoo rau kev siv sab nraum zoov, tab sis lawv tsis nyob hauv tib pawg xws li stainless hlau lossis tsis yog -ferrous washers rau kev tiv thaiv xeb mus tas li.
Q: Dab tsi yog lub tshuab ntxhua khaub ncaws zoo tshaj plaws rau kev siv dej ntsev thiab ntug dej hiav txwv?
- A: 316 marine- qib stainless hlau yog qhov zoo tshaj plaws dav - lub hom phiaj ntxhua khaub ncaws rau dej ntsev thiab ntug dej hiav txwv. Rau qhov xav tau tshaj plaws hauv qab dej thiab hnyav- hnav daim ntaub ntawv marine, aluminium bronze lossis silicon bronze washers muab ntau dua corrosion thiab hnav tsis kam.
Q: Puas yog lub tshuab ntxhua khaub ncaws puas xeb?
- A: Tsis yog, tooj dag tsis muaj hlau, yog li nws tsis tuaj yeem tsim hlau oxide xeb. Thaum lub sij hawm nws yuav tsim ib tug npub tarnish los yog patina, tab sis qhov no yog ib tug tiv thaiv txheej txheej uas tsis degrade cov txheej txheem kev ua tau zoo.
