Kev Npaj Thiab Siv Cov Khoom Uas Tsis Muaj Cov Xim Xim Xim Xim
Kev ua tau zoo thiab kev ua tau zoo ntawm cov neeg siv khoom thiab cov khoom lag luam, nrog rau qhov yuav tsum tau ua kom pom thiab ua haujlwm ntev, yog qhov txhim kho tas li; Raws li qhov tshwm sim, xav txog qhov ecological yam ntawm cov khoom, qhov kev thov kom ruaj khov dua tab sis cov xim zoo nkauj tau nce tsis tu ncua.
Complex inorganic pigments tau dhau los ua ib qho tseem ceeb rau cov qauv tsim los ntawm kev ua kom zoo ntawm cov chromium thiab npib tsib xee titanium daj chemistry, muab ntau yam cuab yeej los npaj kev lag luam, ruaj khov, thiab cov txheej txheem tshiab hauv ntau xim (los ntawm daj mus rau ntsuab, xiav, thiab dub) . Nws yog ua los ntawm cov hlau ions xws li zinc, hlau, titanium, npib tsib xee, cobalt, manganese, trivalent chromium, thiab antimony, uas muaj kev nyab xeeb nyob rau hauv lattices ruaj khov.
Hloov cov organic pigments tuaj yeem ua tiav cov txheej txheem ntau dua, vim tias lawv qhov nqus roj tsawg heev tuaj yeem ua rau cov xim ntau dua. Yog li ntawd, nws yog feem ntau siv ua ke nrog cov organic pigments los tsim cov xim ci ntsa iab, xws li cov xim tsis muaj hlau lead.
Vim lawv lub teeb tsis kam, kub tsis kam, tshuaj tiv thaiv (xws li kua qaub thiab alkali), thiab huab cua tsis kam, lawv kuj yog tshwj xeeb tshaj yog haum rau cov coatings uas yuav tsum tau ua raws li cov qauv kev ua haujlwm siab. Cov no suav nrog, piv txwv li, cov hmoov coatings thiab coil coatings, ci xim, nrog rau cov khoom siv yas thiab cov khoom siv sab nraud xws li cov cement, pob zeb, cov ru tsev, thiab cov ntawv thov ceramic.
