Cov kev xav txog kev xaiv cov rivets

Cov rivets thaum ub yog cov pegs me me ua los ntawm ntoo lossis pob txha. Lub cev hlau deformation thaum ub yuav yog tus poj koob yawm txwv ntawm cov rivets uas peb paub. Tsis muaj kev poob siab tias lawv yog cov txheej txheem qub ntawm kev sib txuas hlau uas tib neeg paub, uas tuaj yeem taug qab mus rau kev siv hlau malleable thaum ntxov. Piv txwv li, hauv Lub Caij Nyoog Bronze, cov neeg Iyiv tau riveted thiab khi rau lub cev ntoo kiv cua ntawm kab sab nraud ntawm lub log slotted ua ke nrog rivets. Tom qab cov neeg Greek ua tiav casting cov duab puab loj nrog bronze, lawv tau riveted cov khoom ua ke nrog rivets. Tam sim no, muaj ntau thiab ntau hom kev txhim kho rivet, feem ntau yog rau kev txhim kho ntawm ntau lub lag luam.

"Cov khoom txheem stainless hlau" yog ib lo lus tshwj xeeb uas npog ntau yam khoom. Cov khoom txheem stainless hlau feem ntau yog siv rau kev khi cov khoom siv tshuab kim dua vim lawv qhov zoo nkauj, ruaj khov, tiv taus corrosion thiab lwm yam ntxwv. Nrog rau kev vam meej ntawm lub zej zog, cov kev xav tau siab kuj tau muab tso rau pem hauv ntej rau cov khoom txheem stainless hlau. Cov khoom txheem stainless hlau kuj xa mus rau cov ntsia hlau stainless hlau, uas yog cov ntsia hlau txheem. Cov lus qhia, qhov loj me thiab qhov kam rau siab yog txhua tus qauv hauv tebchaws.

Cov khoom siv txheem ntawm cov hlau tsis xeb muaj lawv tus kheej cov kev cai rau cov ntaub ntawv tsim khoom. Feem ntau cov khoom siv hlau tsis xeb tuaj yeem ua rau cov hlau xaim lossis cov hlau rau kev tsim cov khoom siv txuas, suav nrog cov hlau tsis xeb austenitic, hlau tsis xeb ferritic, hlau tsis xeb martensitic thiab hlau tsis xeb precipitation hardening. Yog li cov ntsiab cai thaum xaiv cov ntaub ntawv yog dab tsi? Kev xaiv cov ntaub ntawv hlau tsis xeb feem ntau yog xav txog los ntawm cov hauv qab no:

1. Cov kev cai ntawm cov khoom siv kho tshuab, tshwj xeeb tshaj yoglub zog ntawm cov ntaub ntawv fastener;

2. Cov kev cai ntawm cov xwm txheej ua haujlwm raukev tiv thaiv corrosion ntawm cov ntaub ntawv;

3. Cov kev cai ntawm qhov kub ua haujlwm ntawm kev tiv thaiv cua sov (lub zog kub siab, kev tiv thaiv oxidation) ntawm cov ntaub ntawv;

4. Cov kev cai rau kev ua haujlwm ntawm cov khoom siv hauv kev siv tshuab tsim khoom;

5. Yuav tsum xav txog lwm yam xws li qhov hnyav, tus nqi thiab kev yuav khoom.
