Qee tus neeg yeej nyiam cov thav duab steel thiab tau nkees ntawm cov neeg uas thuam cov hlau ua cov khoom siv. Yog li nyob rau hauv cov tshuaj tiv thaiv coined "Steel yog tiag" los qhia tias nws yog ib qho khoom tsim nyog rau kev ua anchors ^H^H^H^H^H^ Tsheb tuam ncej.
Yog cov tsheb kauj vab steel nrawm?
Cov tsheb kauj vab hlau kim dua- Cov tsheb kauj vab steel nqi ntau dua li txhuas. … Koj yuav caij qeeb dua thiab npog hauv av tsawg dua nrog cov ncej steel- Vim yog lub thav duab flex, hnyav dua, thiab aerodynamics tsis zoo, koj yuav zaum caij qeeb qeeb qeeb nruab nrab thaum caij steel ncej.
Puas steel ncej tsim nyog?
Steel tej zaum yuav muaj tiag, tab sis nws kuj yog hnyav. Txawm li cas los xij, nws kuj tseem muaj qhov tshwj xeeb caij nplooj ntoos hlav zoo, uas ua kom muaj kev nplij siab nyob ntev mais. Kev kho yog ib qho yooj yim heev, thiab hlau yog ruaj heev - txawm tias nws qhib rau corrosion.
Koj tuaj yeem qhia tau li cas yog tus ncej yog hlau?
Yog cov hlau nplaum khov kho rau lub raj, nws yog tsim los ntawm cov hlau. Txawm hais tias cov hlau nplaum tseem tuaj yeem nyiam rau titanium, nws yuav tsis muaj kev sib raug zoo zoo li koj tau txais nrog hlau. Yog tias tsis muaj qhov ntxim nyiam, lub raj yuav ua los ntawm lwm yam uas tsis yog hlau, feem ntau yog txhuas lossis carbon.
Vim li cas cov tsheb kauj vab hlau tau yooj yim?
Raws li qhov tseeb, cov ncej steel niaj hnub no siv cov raj zoo uas muaj zog thiab lub teeb. Nrog rau qhov ntawd hauv siab, cov txiaj ntsig rau cov thav duab steel yog tias lawv muaj zog heev thiab ib txwm ua kom nqus taukev vibration. Qhov no ua rau cov tsheb kauj vab steel zoo kawg thiab ruaj khov.
