Cov ntawv thov

Nws yog siv ua raw khoom rau kev tsim cov lithpone. Nws kuj tseem siv rau hauv kev lag luam fiber ntau, zinc plating, tshuaj tua kab. Nws yog siv rau hauv cov chiv keeb thiab cov khoom noj pub, thiab lwm yam.
Feem ntau nws yog siv ua cov khoom siv raw rau kev tsim cov lithophane thiab zinc ntsev, mordant rau kev luam ntawv thiab zas xim, tshuaj tiv thaiv rau ntoo thiab tawv, tshuaj tua kab rau kev tiv thaiv kab mob thiab kab tsuag ntawm cov ntoo txiv hmab txiv ntoo, emetic rau tshuaj, tshuaj ua kom pom tseeb thiab khaws cia rau cov kua nplaum pob txha, thiab tseem yog cov khoom siv raw tseem ceeb rau kev tsim cov tshuaj fiber. Tsis tas li ntawd, nws kuj siv rau hauv electroplating, electrolysis thiab kev lag luam ntawv. Nws yuav tsum khaws cia rau qhov chaw qhuav.
Cov txheej txheem ntau lawm: ntxiv zinc oxide rau hauv cov tshuaj dilute kom ua slurry. Ntxiv sulfuric acid rau kev ua tshuaj, thiab ntxiv zinc hmoov los hloov tooj liab, cadmium, nickel, thiab lwm yam tom qab lim, cov lim dej raug cua sov. Ntxiv potassium permanganate rau oxidize hlau, manganese thiab lwm yam tsis huv. Tom qab lim, nws raug clarified, concentrated, txias thiab crystallized, centrifuged thiab ziab.
Ntim: 25kg thiab 50kg sab hauv yas sab nraud polypropylene woven hnab

Kev Ceev Faj Txog Kev Khaws Cia

Khaws cia rau hauv qhov chaw txias thiab muaj cua nkag. Khaws cia kom deb ntawm cov qhov cub hluav taws thiab cov chaw kub. Tiv thaiv kom tsis txhob raug tshav ntuj ncaj qha. Ntim thiab kaw. Yuav tsum khaws cia cais ntawm cov tshuaj oxidant thiab txwv tsis pub khaws cia sib xyaw. Qhov chaw khaws cia yuav tsum muaj cov khoom siv tsim nyog los tiv thaiv kev xau.
