1. Yuav ua li cas xaiv cov khoom ntawm stainless hlau bolts zoo dua?
Stainless hlau feem ntau yog hais txog cov hlau uas muaj peev xwm tiv thaiv corrosion los ntawm huab cua, dej, kua qaub, alkali hlau ntsev los yog lwm yam xov xwm. Raws li cov khoom sib txawv ntawm cov alloy, qhov tseem ceeb ntawm corrosion kuj thiab acid kuj. Thaum qee cov hlau tsis xeb, lawv tsis tas yuav acid resistant, thiab acid resistant steel feem ntau yog xeb resistant.
Kev xav tau rau cov khoom siv kho tshuab, tshwj xeeb tshaj yog lub zog, ntawm cov khoom siv stainless hlau ntsia hlau; 2. Cov kev xav tau rau corrosion kuj ntawm cov ntaub ntawv raws li kev ua haujlwm.
2. Stainless hlau bolts yuav xeb vim qhov kev tiv thaiv zaj duab xis ntawm stainless hlau puas?
Stainless hlau bolts ntsib cov dej uas condensed nyob rau hauv cov huab cua. Cov pa phem txhais tau hais tias lawv muaj cov tshuaj sulfur ntau lossis carbon monoxide. Thaum lawv nkag mus rau hauv dej, lawv tsim sulfuric acid thiab hydroxide, uas chemically corrode stainless hlau bolts. Stainless hlau bolts xeb vim tias cov yeeb yaj kiab tiv thaiv ntawm cov hlau tsis huv raug rhuav tshem, stainless hlau yog oxidized thiab nws cov corrosion kuj tsis muaj zog, yog li stainless hlau bolts tseem yuav xeb.
3. Kev ceev faj rau khaws cov hlau tsis muaj steel bolts:
Thaum khaws cov hlau tsis muaj steel bolts, cov khoom tiv thaiv yuav tsum muaj zog, thiab nyob rau hauv ib qho chaw qhuav, tsis txhob muab cov galvanized hlau bolts rau hauv qhov chaw ntub dej. Tsis tas li ntawd, ceev faj tsis txhob ua nruj me ntsis hauv qab lub thawv thaum lub sijhawm ntim khoom. Cov khoom uas tsis yog tus qauv uas yuav tsum tau tshwj xeeb yuav tsum tau ntim rau hauv lub hnab ntim khoom lossis lwm yam khoom, thiab yuav tsum tau saib xyuas kom tsis txhob muaj kev sib tsoo.
Lub hardness ntawm stainless hlau ntsia liaj qhov rooj qhia cov khoom muaj peev xwm tiv taus cov khoom nyuaj nias rau hauv nws qhov chaw. Nws yog ib qho tseem ceeb ntawm kev ua tau zoo ntawm cov khoom siv hlau.
Feem ntau, qhov siab dua qhov hardness, qhov zoo dua qhov hnav tsis kam. Feem ntau siv hardness ntsuas yog Brinell hardness, Rockwell hardness thiab Vickers hardness. Thaum kuaj lub hardness ntawm stainless hlau txiv ntseej, bolts yam tsis muaj kev kho cua sov yuav tsum tsuas yog ua rau saum npoo hardness nyob rau hauv lub txais ntau yam. Yog tias nws yog cov ntsia hlau kho cua sov, lub hardness yuav tsum tau nce rau ntawm qhov chaw tsis muaj txoj kab uas hla, thiab qhov kev ntsuam xyuas hardness yuav tsum tau nqa tawm ntawm 1/2R ntawm qhov chaw, thiab qhov hardness yuav tsum tau raws li tus qauv.
