Thaum nws los txog rau alloy saw hniav, nws yeej tsis muaj neeg txawv rau nws, vim hais tias lawv muaj ntau heev nyob rau hauv peb lub neej niaj hnub. Alloy saw hniav yog ua los ntawm cov hlau alloy. Cov hniav saws yuav corrode nrog xeb yog tias tsis khaws cia thiab tsis siv sijhawm dhau mus. Lub sijhawm no, carbide pom cov hniav siv tsis tuaj yeem siv thiab peb yuav tsum ua kom tsis muaj zog ua ntej lawv tuaj yeem siv tau.
1. Yam ua rau xeb
Feem ntau hais lus, roj carbide saw hniav tsis tu ncua los tiv thaiv xeb thiab qhov chaw lawv nyob rau hauv qhov chaw ventilated thiab qhuav thaum tsis sivd. Lub ntim yuav tsum tsis txhob puas. Nws yog qhov zoo tshaj los khaws lawv ntawm cov txee ntoo. If lub ntim puas lawm thiab alloy saw hniav tas li raug rau qhov chaw ntub dej, tnws cov dej pos huab yuav tuaj rau hauv kev sib cuag nrog carbide saw hniav los ntawm kev puas tsuaj nkag, ua rau oxidation.
Yog li ntawd, thaum hlau alloy saw hniav tsis siv, lawv yuav tsum tau teem nyob rau hauv qhuav thiab ventilated qhov chaw.
2. Yuav ua li cas nrog rusty alloy saw hniav
Yog tias koj pom tias cov saw hniav yog xeb, tsis txhob siv nws li niaj zaus. Qhov no yuav yooj yim ua rau kev puas tsuaj rau sawb, tshwj xeeb tshaj yog ua rauhauv hniav tawg tawg thiab lwm yam teeb meem. Peb yuav tsum ua derusting thiab lwm yam haujlwm ua ntej siv nws.
1) Ua ntej txheeb xyuas qhov xeb. Yog nws yog lub cev ntawm saw hniav, nws yog ib qho yooj yim mus nrog nws. Tsuas yog siv ib txwm txoj kev ua derusting.
2) Yog tias qhov xeb nyob ntawm cov hniav, nws yuav yog me ntsis dag. Hauv qhov no, nws yuav tsum tau kho nrog lub pob zeb diamond sib tsoo raws li cov cuab yeej sib tsoo tiav, vim cov hniav saws yog qhov tseem ceeb tshaj plaws ntawm cov saw hniav. Thaum ua tsis raug cai, nws yuav cuam tshuam rau kev siv cov carbide saw hniav, thiab nws yuav ua rau cov hniav saws raug tshem tawm.
Qhov tseeb, txoj hauv kev zoo tshaj plaws los daws cov rusted saw hniav yog kev saib xyuas tsis tu ncua thiab qee qhov kev nthuav dav. Tsuas yog kev tiv thaiv yog txoj hauv kev zoo tshaj plaws los daws qhov teeb meem.
