Cov khoom siv tooj dag / tooj liab pob

Cov ntsiab lus kev paub txog tooj liab liab：

Tooj liab kuj tseem hu ua tooj liab liab, yog cov tshuaj yooj yim ntawm tooj liab. Nws yog lub npe rau nws cov xim-liab xim tom qab ib oxide zaj duab xis yog tsim rau nws saum npoo. Tooj liab liab yog kev lag luam tooj liab ntshiab nrog kub yaj ntawm 1083°C, tsis muaj kev sib hloov pauv, thiab qhov txheeb ze ntawm 8.9, uas yog tsib zaug ntawm cov khoom siv ntawm magnesium. Qhov loj ntawm tib cov ntim yog kwv yees li 15% hnyav dua li cov dog dig.

Nws yog tooj liab nws muaj qee qhov nyiaj ntawm oxygen, yog li nws tseem hu ua tooj liab-muaj tooj.

Tooj liab yog ntau hom tooj liab, uas feem ntau tuaj yeem kwv yees li tooj liab ntshiab. Nws muaj cov hluav taws xob zoo conductivity thiab plasticity, tab sis nws lub zog thiab hardness yog kuj tsis zoo.

Tooj liab tau zoo thermal conductivity, ductility thiab corrosion kuj. Ib txoj lw impurities hauv tooj liab liab muaj kev cuam tshuam loj rau qhov hluav taws xob thiab thermal conductivity ntawm tooj liab. Ntawm lawv, titanium, phosphorus, hlau, silicon, thiab lwm yam cuam tshuam txo cov kev coj ua, thaum cadmium, zinc, thiab lwm yam muaj cov nyhuv me. Sulphur, selenium, tellurium, thiab lwm yam muaj solubility tsawg heev hauv tooj liab, thiab tuaj yeem tsim cov xim av sib xyaw nrog tooj liab, uas tsis tshua muaj txiaj ntsig ntawm kev siv hluav taws xob, tab sis tuaj yeem txo cov khoom ua cov yas.

Tooj liab liab muaj cov tshuaj tiv thaiv zoo hauv huab cua, dej hiav txwv, qee qhov tsis muaj oxidizing acids (hydrochloric acid, dilute sulfuric acid), alkali, ntsev tov thiab ntau yam cov organic acids (acetic acid, citric acid), thiab yog siv hauv tshuaj lom neeg kev lag luam. Tsis tas li ntawd, liab tooj liab tau zoo weldability thiab tuaj yeem tsim rau hauv ntau yam khoom tiav thiab ua tiav los ntawm kev txias thiab thermoplastic.
