Cov yeeb nkab hlau vuam:
Cov Zoo: Cov yeeb nkab hlau welded ua tau zoo heev thiab tus nqi qis. Nws siv tau rau qee qhov kev sib txuas tshuaj uas tsis muaj qhov xav tau siab heev thiab muaj cov kev xav tau tshwj xeeb rau kev tiv thaiv corrosion thiab lwm yam khoom ntawm cov yeeb nkab hlau.
Cov xwm txheej siv: Piv txwv li, hauv lub tshuab kho dej khib nyiab ntawm lub Hoobkas tshuaj, nws yog siv los thauj qee cov dej khib nyiab uas tau dhau los ua kev kho mob ua ntej thiab muaj qhov yuav tsum tau ua kom huv si me ntsis rau cov kav hlau, lossis yog siv los thauj cua hauv qee lub tshuab cua.
3. Lub raj hlaucov qauv
Cov qauv kev huv: Cov raj hlau rau kev siv tshuaj yuav tsum ua raws li cov qauv kev huv huv. Lub ntsej muag sab hauv ntawm cov yeeb nkab hlau yuav tsum du thiab yooj yim ntxuav thiab tua kab mob kom tiv thaiv kev loj hlob ntawm cov kab mob thiab cov kab mob me me. Piv txwv li, qhov roughness sab hauv ntawm cov yeeb nkab hlau yuav tsum tau tswj hwm hauv qee qhov ntau yam kom tiv thaiv cov kua seem los ntawm kev yug me nyuam cov kab mob thiab cuam tshuam rau qhov zoo ntawm cov tshuaj.
Cov qauv zoo: Lub zog, kev tawv thiab lwm yam khoom siv kho tshuab yuav tsum ua tau raws li qhov yuav tsum tau siv rau hauv cov txheej txheem tshuaj. Piv txwv li, hauv qee cov kav dej thauj kua tshuaj uas yuav tsum tau tiv taus qee qhov siab, cov kav hlau yuav tsum muaj lub zog txaus kom ntseeg tau tias cov kav dej yuav tsis tawg, yog li zam kev xau tshuaj thiab kev raug mob ntau lawm. Piv txwv li, qee cov kav hlau hauv GB / T8163-2008 (cov kav hlau tsis muaj qhov sib txuas rau kev thauj cov kua) tus qauv tuaj yeem siv ua cov kav dej thauj kua hauv kev tsim tshuaj.
