Kev Siv
Nws yog siv rau electroplating, kev tsim cov khoom siv high-purity metallic chromium, dyes, synthetic roj hmab thiab roj refining, thiab lwm yam.
Chromium trioxide yog cov khoom siv tseem ceeb rau electroplating chromium. Hauv kev tsim cov electroplating chromium, cov ntsiab lus ntawm chromic anhydride sib txawv heev, xws li 50 txog 500 g / L. Los ntawm kev tswj qhov kub thiab qhov ceev tam sim no kom raug, ib txheej ci tuaj yeem tau txais ntawm cov khoom plated du. Nws cov kua kuj tseem siv tau ua zaj duab xis passivation rau zinc txheej, txhim kho lawv cov kev ua tau zoo tiv thaiv.
Nws yog siv los ua ib qho tshuaj reagent analytical thiab muaj zog oxidant, thiab kuj siv rau hauv kev tsim cov chromate
Chromium trioxide feem ntau yog siv rau hauv kev lag luam electroplating ua cov khoom siv raw rau electroplating chromium ntawm tsheb kauj vab, tshuab xaws, moos, twj paj nruag, teeb, khoom siv niaj hnub, thiab lwm yam. Nws kuj tseem siv los tsim cov hlau chromium uas muaj cov khoom ntshiab siab. Nws yog cov khoom siv raw rau kev tsim cov chromium oxide ntsuab thiab zinc chrome daj. Nws tseem yog cov khoom siv raw rau kev tsim cov catalysts hloov pauv kub qis, cov catalysts hloov pauv kub siab thiab cov catalysts synthesis methanol siab siab. Nws yog siv ua mordant hauv kev zas xim ntawm cov ntaub plaub thiab ua oxidant hauv kev lag luam luam ntawv thiab zas xim. Tsis tas li ntawd, nws kuj tseem siv rau kev khaws cia ntoo.
Cov tshuaj oxidants, cov tshuaj reagents tsom xam spectral, kev txiav txim siab ntawm cov pa roj carbon thiab phosphorus, kev ntxuav cov roj tawv thiab ethylene, kev tsom xam roj hauv kev tsim cov chiv nitrogen, kev tsom xam tag nrho cov hlau, kev sim hauv chaw soj ntsuam kev tiv thaiv cog qoob loo. Kev tsim cov ntsev chromium, thiab lwm yam.
Ntim thiab Xa Khoom
25kg/nruas, 50kg/nruas raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
