Thermochromic xim siv kua siv lead ua kua los yog leuco dye technology. Tom qab absorbing ib tug npaum li cas ntawm lub teeb los yog kub, lub crystallic los yog molecular qauv ntawm cov xim reversibly hloov nyob rau hauv xws li ib txoj kev uas nws absorbs thiab emits lub teeb ntawm ib tug txawv wavelength tshaj nyob rau hauv qis kub.

Kuj tseem paub yog, lub ntsuas kub ua kua siv lead ua ua haujlwm li cas?

A Crystal ntsuas kub , kub sawb los yog yas strip ntsuas kub yog hom ntsuas kub uas muaj kub-rhiab heev (thermochromic) kua siv lead ua kua nyob rau hauv ib lub hnab yas uas hloov xim los qhia qhov kub thiab txias. Kev daws teeb meem ntawm siv lead ua kua sensors yog nyob rau hauv 0.1 ° C ntau yam.

Qhov thib ob, cov khoom siv thermochromic yog dab tsi? 2.4 Thermochromics Cov khoom siv thermochromic hloov pauv lawv cov xim los ntawm kev hloov pauv kub. Cov ntaub ntawv thermochromic feem ntau yog cov organic leuco-dye mixs, tsim los ntawm cov xim qub, tus tsim xim, thiab cov kuab tshuaj. Cov xim qub feem ntau yog cyclic ester thiab txiav txim siab cov xim hauv paus.

Ib sab saum toj no, cov kua siv lead ua kua hloov xim li cas?

Cov molecules hauv a ua kua siv lead ua tuaj yeem txav mus los ntawm nws tus kheej, zoo li hauv a ua kua , tab sis nyob twj ywm me ntsis, raws li nyob rau hauv ib tug siv lead ua (khoom). Cov no kua siv lead ua kua teb rau kev hloov nyob rau hauv kub los ntawm hloov xim . Raws li qhov kub thiab txias, lawv xim hloov los ntawm liab mus rau txiv kab ntxwv, daj, ntsuab, xiav, thiab ntshav.

Cov xim thermochromic ntev npaum li cas?
