Plasticity Thiab Cov Ntawv Yuav Los Ntawm Cov Refractory Cib

Tom qab cov tshuaj raug rau sab nraud quab yuam, nws deforms yam tsis muaj kab nrib pleb. Tom qab lub zog sab nraud raug tso tawm, daim ntawv deformed tseem nyob thiab tsis rov qab los rau lub xeev qub yog hu ua plasticity. Plasticity yog txheej txheem tseem ceeb moulding txheej txheem rau kev cog lus av nplaum. Plasticity muaj feem xyuam nrog kev muaj peev xwm ntawm cov khoom sib nqus kom nqus tau cov dej, thaj tsam tshwj xeeb hauv cheeb tsam thiab dej ntim. Piv txwv li, tom qab ntxiv dej rau hauv av nplaum, zaj duab xis dej yog adsorbed nyob rau saum npoo ntawm muaj coob ntawm cov av nplaum, thiaj li hais tias cov khoom me me tsis tsuas yooj yim xaub nyob rau sab nraud quab yuam, tab sis kuj muaj qee yam quab yuam. , Uas muaj high plasticity.

Kev ntsuas ntsuas yas muaj plasticity index txoj kev thiab txoj kev ntsuas yas tau yas, thiab nws tseem tuaj yeem ntsuas los ntawm plasticity ya raws. Lub cim (plasticity index) hais txog qhov sib txawv ntawm cov dej thaum cov av nplaum yog nyob rau lub xeev yas, thiab nws tus nqi yog sib npaug ntawm qhov sib txawv ntawm cov kua (kua txwv) thiab txwv (yas txwv). Qhov ua kua ua kua yog qhov txwv siab tshaj ntawm cov dej ntsiab lus thaum cov av nkos nyob hauv lub xeev yas. Thaum cov dej ntsiab lus ntau dua qhov txwv ua kua, cov av nkos yog nyob hauv lub xeev ib nrab. Qhov sib txawv nruab nrab ntawm qhov ua kua ua kua thiab txwv cov yas, qhia raws li feem pua, yog qhov ntsuas siab ua plasticity.
