Frost Resistance ntawm Ductile Hlau Yeeb Nkab

Cov yeeb nkab hlau, nrog nws cov khoom siv zoo heev thiab cov khoom siv sab nraud, yog tus tuav ntawm cov kav dej xa dej hauv kev lag luam. Kev ua dej num tuaj yeem ua tiav txawm tias nyob rau hauv cov av sib npaug xws li thaj av saline-alkali, marshland, txoj kab siab thiab suab puam. Hom tshiab ntawm cov yeeb nkab hlau yeeb nkab muaj kev tiv thaiv zoo Frost. Tsuav tsis muaj qhov xwm txheej tshwj xeeb, nws yuav tsis tshwm sim Frost tawg thiab cov yeeb nkab tawg. Txawm li cas los xij, cov kav dej me me thiab cov ntsuas dej hauv thaj chaw nyob thiab lub tsev tshiab lub zos nyob rau hauv txoj kev qhib. Txawm hais tias cov ntaub ntawv thermal rwb thaiv tsev tau muab qhwv rau sab nraum cov kav dej thiab "cov khaub ncaws caij ntuj no" tau muab tso rau hauv cov khoom siv dej xws li cov ntsuas dej, thaum qhov kub thiab txias poob qis, nws tseem yuav tsum tau ua txoj haujlwm zoo hauv kev tiv thaiv dej hauv tsev thiab sab nraum zoov. muab khoom siv. Ob leeg nodular cam khwb cia hlau thiab zoo tib yam cam khwb cia hlau muaj graphite monomer, uas txhais tau hais tias cam khwb cia hlau yog ib tug sib tov ntawm hlau thiab graphite. Cov graphite hauv cov hlau cam qub muaj nyob rau hauv daim ntawv ntawm flakes. Lub zog ntawm graphite yog tsawg heev, yog li nws yog sib npaug rau ntau flake voids hauv cam khwb cia hlau. Yog li ntawd, lub zog ntawm cov hlau cam khwb cia zoo tib yam yog qhov tsawg thiab nkig. Cov graphite nyob rau hauv graphite cam khwb cia hlau yog kheej kheej, uas yog sib npaug rau ntau lub voj voos kheej kheej hauv cam khwb cia hlau. Kev cuam tshuam ntawm cov voids kheej kheej ntawm lub zog ntawm cam khwb cia hlau yog me dua li ntawm cov voids flaky, yog li lub zog ntawm nodular cam khwb cia hlau muaj zog ntau dua li cov hlau cam khwb cia.
