Q:Dab tsi yog qhov muaj zog ntawm tooj liab pop rivets thiab tooj dag pop rivets?
A： Cov tooj liab ntshiab, tseem hu ua tooj liab liab, muaj qhov ntom ntom ntawm (7.83g / cm3) thiab melting point ntawm 1083 degrees. Nws tsis yog hlau nplaum, nws muaj qhov zoo conductivity, thermal conductivity, corrosion kuj thiab toughness.
Qhov ntom ntawm tooj dag (8.93g / cm3) yog siv rau hauv ob sab phlu nrog cov neeg kho tshuab bearing hav txwv yeem, uas yog hnav-resistant.
Qhov ntom ntawm "tooj dag" yog siab dua li ntawm tooj liab liab, thiab "tooj dag" yog tawv nrog zoo rigidity.
