Tsis yog tag nrho xim kev hloov pauv qhia a tshuaj tiv thaiv . Tsuas yog sib xyaw xim yog lub cev hloov . Tsis muaj cov khoom tshiab tsim. Vim lub cev thiab tshuaj ua-up ntawm cov pigments siv los ua xim sib txawv, tus nqi thiab kev ncua deb ntawm lawv mus raws li daim ntawv phuam nws txawv, ua rau lub xim cais tawm.
Ib yam li ntawd ib tug yuav nug, dab tsi yog piv txwv ntawm kev hloov xim ntawm cov tshuaj tiv thaiv?
Thaum tooj liab reacts nrog cov khoom (oxygen, dej thiab carbon dioxide), nws tig los ntawm nws cov khoom xim ntawm reddish-xim av rau ntsuab. Qhov no tshuaj tiv thaiv yog hydrated tooj liab carbonate, thiab nto moo piv txwv ntawm nws yog tus pej thuam ntawm Liberty.
Tom qab ntawd, lo lus nug yog, 5 qhov pov thawj ntawm kev hloov tshuaj lom neeg yog dab tsi? Tsib txawv cov cim xws li tsw, kub hloov , precipitate tsim, zus tau tej cov pa npuas, thiab ib tug xim hloov.
Tsis tas li ntawd, 7 cov cim qhia ntawm cov tshuaj tiv thaiv tshuaj yog dab tsi?
Xya yam uas qhia tias muaj kev hloov tshuaj lom neeg tshwm sim
- Gas npuas tshwm. Gas npuas tshwm tom qab muaj tshuaj lom neeg cov tshuaj tiv thaiv tau tshwm sim thiab cov sib tov ua saturated nrog roj.
- Tsim ib tug Precipitate.
- Xim hloov.
- Kub Hloov.
- Kev tsim lub teeb.
- Hloov ntim.
- Hloov hauv tsw lossis saj.
Koj ua li cas thiaj li hloov cov kua dej?
Cov lus qhia
- Ncuav dej rau hauv lub khob khoob kom txog thaum nws puv 3/4 ntawm txoj kev.
- Ntxiv 1-2 tee ntawm cov zaub mov xiav xim rau hauv dej thiab do kom txog thaum sib xyaw.
- Sau ib lub lauj kaub puv dej.
- Tau ib lub tais loj loj thiab tso lub khob nrog dej xiav rau hauv nruab nrab ntawm lub tais.
