Rust Resistance Ntawm Stainless Hlau Screws

Subconsciously, peb txhua tus xav li ntawdstainless hlau screwsyuav tsis xeb, tab sis qhov no tsis yog li ntawd. Nyob rau hauv ib puag ncig hnyav, stainless hlau screws kuj tuaj yeem corrode thiab xeb, uas yog qhov tshwm sim feem ntau. Txawm li cas los xij, feem ntau stainless hlau ntsia hlau yog siv hauv tsev lossis hauv cov khoom siv hluav taws xob, qhov chaw ua haujlwm zoo, tsis muaj kuab paug los ntawm cov dej hiav txwv lossis cov huab cua muaj zog acid. Yog li ntawd, qhov tshwm sim ntawm xeb yog qhov tsawg, yog li peb tsis tshua pom xeb ntawm lawv.

Peb tsuas tuaj yeem hais tias stainless hlau screws muaj kev tiv thaiv corrosion zoo heev thiab muaj zog tiv thaiv corrosion nyob rau hauv ib puag ncig atmospheric zoo tib yam. Tab sis thaum siv nyob rau hauv ntug hiav txwv dej los yog lwm yam corrosive ib puag ncig, lawv tseem yuav xeb nyob rau lub sij hawm. Precisely vim hais tias ntawm qhov sib txawv nyob rau hauv kev pab cuam ib puag ncig, nws yog tsim nyog los nkag siab txog cov yam ntxwv ntawm stainless hlau screws los xaiv thiab siv lawv tsim nyog thiab zoo. Nyob rau hauv qhov sib txawv kub thiab av noo, tsim nyog stainless hlau ntsia hlau tuaj yeem xaiv, xws li 304 stainless hlau ntsia hlau lossis 316 stainless hlau screws.

Vim li cas Stainless Hlau Screws Rust?

Kev tiv thaiv corrosion ntawm stainless hlau screws tsuas yog nyob ntawm cov khoom xws li chromium thiab npib tsib xee uas muaj nyob rau hauv cov khoom nws tus kheej. Cov ntsiab lus no tsim cov oxide tiv thaiv zaj duab xis (passive film) ntawm qhov chaw, yog li tiv thaiv atmospheric corrosion. Raws li kev xav, kev txhim kho cov khoom siv kuj tuaj yeem txhim kho kev tiv thaiv corrosion, tab sis stainless hlau ntsia hlau yog cov qauv uas yuav tsum tau muaj ntau lawm, ua rau tus kheej hloov kho cov khoom siv hlau tsis zoo.

Yog li ntawd, muaj qee qhov kev ceev faj ua raws li thaum lub sijhawm teeb tsa thiab sivstainless hlau screws:

Stainless hlau ntsia hlau yuav tsum tau ntsia rau ntawm - qhov chaw yuav tsum muab khaws cia rau hauv qhov chaw huv si, qhov cua, thiab qhov chaw qhuav;

Ua ntej installation, xyuas seb puas muaj impurities xws li av thiab hlau khib nyiab hauv cov xov. Cov impurities no yuav tsub zuj zuj nyob rau hauv ib puag ncig sab nraum zoov thiab ua ib qho inducer ntawm corrosion;

Ua tib zoo saib cov kev hloov pauv ntawm qhov kub thiab txias thaum lub sijhawm teeb tsa. Qhov sib txawv ntawm qhov kub thiab txias ntau dhau yuav ua rau muaj dej noo. Hauv qhov no, tsis txhob maj rau nruab; Hloov chaw, ua ntej tso cov ntsia hlau rau hauv qhov chaw qhuav kom qhuav ua ntej ua haujlwm, kom tsis txhob muaj kev sib khi cov dej hauv cov xov khoob thiab ua rau corrosion.

Lub hauv paus ntawm kev tiv thaiv xeb rau stainless hlauntsia hlaunyob rau hauv qhov chaw tiv thaiv zaj duab xis (passive film). Cov yeeb yaj kiab no zoo ib yam li cov txheej txheem electroplated ntawm carbon steel bolts, uas cais cov hlau substrate los ntawm corrosive media xws li huab cua thiab noo noo, yog li ua tiav kev tiv thaiv xeb. Thaum cov yeeb yaj kiab tiv thaiv no puas lawm (xws li, los ntawm cov khoom siv khawb, tshuaj lom neeg corrosion, thiab lwm yam), stainless hlau screws yuav pib corrode thiab xeb. Yog li ntawd, stainless hlau screws tsis tiv thaiv xeb; lawv tsuas yog muaj zog xeb tiv taus thiab tsis nquag xeb.
