Xaiv cov khoom siv ntsia hlau zoo raws li daim ntawv thov ib puag ncig yog qhov tseem ceeb, yuav tsum tau ua tib zoo xav txog kev pheej hmoo corrosion, kev xav tau kev ntxhov siab, qhov kub thiab txias, thiab cov nqi siv nyiaj. Lub durability thiab kev nyab xeeb ntawm cov ntaub ntawv sib txawv heev nyob rau hauv ib puag ncig sib txawv; xaiv cov khoom tsim nyog tuaj yeem tiv thaiv kom tsis txhob xoob, tawg, lossis xeb.
1. Qhov chaw ntub dej lossis sab nraum zoov: Stainless hlau nyiam
Nyob rau hauv rainy, ntub dej, los yog ntsev tsuag ib puag ncig (xws li chaw ntug hiav txwv dej, txuas hniav, thiab nkoj), stainless hlau screws (xws li 304 thiab 316) yog thawj xaiv.
304 Stainless Steel: High corrosion-resistant, haum rau cov chaw sab nraum zoov, lub tsev ntaub thaiv phab ntsa, txoj kev teeb, thiab lwm yam.
316 Stainless Hlau: Muaj cov molybdenum, muaj zog tiv thaiv chloride corrosion, haum rau siab - ntsev tsuag marine ib puag ncig lossis cov khoom siv tshuaj.
Yog tias cov peev nyiaj tsawg, galvanized carbon steel screws tuaj yeem siv tau, tab sis lawv cov xeb- tiv taus lub neej luv dua, yuav tsum tau saib xyuas tsis tu ncua.
2. Siab -Tsuas Kub los yog Cav Qhov Chaw Ib puag ncig: Kub-Resistant Stainless Hlau lossis Alloy Steel
Nyob rau hauv qhov siab - qhov kub thiab txias xws li lub cav compartments thiab tso pa, cov pa roj carbon zoo tib yam yog oxidation thiab tsis ua hauj lwm.
Stainless hlau (xws li, 309, 310): Resistant mus rau siab -kub oxidation, tuaj yeem ua haujlwm ruaj khov hauv ib puag ncig siab dua 600 degree.
Alloy steel (piv txwv li, 40Cr, 35CrMo): Lub zog muaj zog, tuaj yeem tiv taus qhov kub thiab txias siab tom qab kev kho cua sov, feem ntau siv rau hauv lub cav mounting Cheebtsam thiab ncua kev kawm ntawv.
Tsis txhob siv aluminium alloy lossis yas screws, vim tias lawv tuaj yeem deformation ntawm qhov kub thiab txias.
3. Siab-kev nyuaj siab lossis qhov tseem ceeb ntawm cov qauv: Siab-lub zog alloy steel. Chassis, ncua kev kawm ntawv, kis tau tus mob, thiab lwm yam., dais enormous vibrations thiab loads.
8.8 qib thiab siab dua alloy steel screws: siab tensile lub zog, tuaj yeem tiv taus cov khoom hnyav, cov khoom siv hauv tsheb thiab cov tshuab hnyav.
Kev kho deg feem ntau siv Dacromet los yog kub-dip galvanizing kom sib npaug tiv thaiv xeb thiab siab zog.
4. Lub teeb yuag daim ntawv thov scenarios: Aluminium alloy los yog titanium alloy. Tsim nyog rau qhov hnyav - qhov chaw siab xws li aerospace, kev sib tw, thiab siab - tsheb kauj vab kawg.
Aluminium alloy screws (xws li 7075): Lub teeb yuag thiab corrosion- tiv taus, tab sis muaj zog qis dua steel screws, ua rau lawv tsis haum rau siab -load daim ntaub ntawv.
Titanium alloy screws: Nrog lub zog nce mus txog ntawm cov hlau, tab sis hnyav tsuas yog 60% ntawm cov hlau, lawv muaj kev tiv thaiv corrosion zoo heev, tab sis kim heev thiab feem ntau siv rau hauv siab -kawg hloov kho lossis cov cuab yeej precision.
