Cov khoom siv bolt feem ntau muaj xws li cov hauv qab no:
1. Carbon steel:Carbon steel boltsyog cov hom feem ntau, nrog zoo zog thiab machinability. Cov khoom siv carbon steel bolt feem ntau suav nrog cov pa roj carbon zoo tib yam (xws li 8.8 qib, 10.9 qib) thiab alloy carbon hlau (xws li 40Cr, 35CrMo, thiab lwm yam).
2. Stainless hlau: Stainless hlau bolts muaj corrosion kuj thiab oxidation tsis kam, ua rau lawv haum rau daim ntaub ntawv nyob rau hauv ntub los yog corrosive ib puag ncig. Cov khoom siv stainless hlau bolt feem ntau suav nrog 304 stainless hlau, 316 stainless hlau, thiab lwm yam.
3. High zog alloy steel:High zog alloy steel boltsmuaj zog dua thiab hardness, ua rau lawv haum rau daim ntaub ntawv uas yuav tsum tau siab loads thiab vibrations. Feem ntau muaj zog alloy steel bolt cov ntaub ntawv muaj xws li hlau alloy (xws li 40CrNiMoA, 42CrMo, thiab lwm yam).
4. Copper: tooj liab bolts muaj zoo conductivity thiab thermal conductivity, thiab feem ntau yog siv nyob rau hauv cov khoom siv hluav taws xob thiab cov ntawv thov uas muaj thermal conductivity siab.
5. Aluminium alloy: Aluminium alloy bolts muaj cov yam ntxwv ntawm lub teeb yuag thiab corrosion kuj, thiab feem ntau yog siv rau hauv kev lag luam xws li aviation thiab tsheb.
Thaum xaiv cov khoom siv ntsia liaj qhov rooj, yam xws li kev siv ib puag ncig, kev xav tau kev ntxhov siab, kev tiv thaiv corrosion, thiab kub yuav tsum tau xav txog. Rau kev siv tshwj xeeb, bolts ua los ntawm cov ntaub ntawv xws li titanium alloy thiab npib tsib xee alloy kuj raug xaiv. Nws raug nquahu kom sab laj cov kws tshaj lij lossis xa mus rau cov qauv thiab cov txheej txheem cuam tshuam raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau.
Ntxiv nrog rau cov khoom siv bolt uas tau hais los saum toj no, kuj tseem muaj lwm yam khoom siv ntsia liaj qhov rooj, raws li hauv qab no:
1. Titanium alloy:Titanium alloy boltsmuaj tsawg ntom ntom, siab zog, zoo corrosion kuj, thiab qaug zog kuj. Lawv feem ntau siv nyob rau hauv kev ua haujlwm ntawm aerospace, cov cuab yeej kho mob, thiab high-end engineering.
2. Nickel alloy: Nickel alloy bolts muaj kev tiv thaiv corrosion zoo heev thiab kev ua haujlwm kub, thiab tsim nyog rau kev lag luam xws li tshuaj lom neeg engineering, lub zog, thiab aviation. Cov khoom siv nickel alloy bolt feem ntau suav nrog Inconel, Hastelloy, thiab lwm yam.
3. Cam khwb cia hlau: cam khwb cia hlau bolts feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum muaj lub zog siab thiab hnav tsis kam, xws li cov cuab yeej siv tshuab, cov qauv loj, thiab lwm yam.
4. tooj dag:tooj dag boltsmuaj zoo corrosion kuj thiab conductivity, thiab feem ntau yog siv nyob rau hauv cov teb xws li kho kom zoo nkauj, rooj tog, thiab cov khoom siv hluav taws xob.
5. Polymers: Hauv qee qhov tshwj xeeb, cov bolts polymer kuj tseem siv tau, xws li hauv cov ntawv thov uas yuav tsum tsis muaj kev sib txuas, kev tiv thaiv corrosion, lossis kev sib txhuam coefficient tsawg.
Nws yuav tsum raug sau tseg tias thaum xaiv cov khoom siv ntsia hlau tsim nyog, kev ntsuam xyuas thiab kev xaiv yuav tsum ua raws li cov kev thov tshwj xeeb, ib puag ncig, thiab kev xav tau. Tsis tas li ntawd, cov qauv tsim nyog thiab cov lus qhia yuav tsum tau ua kom ntseeg tau tias qhov zoo thiab kev ua haujlwm ntawm cov khoom siv ntsia hlau ua tau raws li qhov yuav tsum tau ua.
