Kev Siv
Ua tus neeg sib koom ua ke hauv lub tshuab calcium/zinc hydroxylate stabilization, nws yog siv los tsim cov fwj dej hauv PVC.
Benzoylmethane siv tau ua ib qho tshuaj reagent los txiav txim siab carbon disulfide thiab thallium, kev txiav txim siab gravimetric ntawm uranium, kev txiav txim siab photometric ntawm U + 4, thiab rho tawm nyiaj, txhuas, barium, beryllium, calcium, cadmium, cobalt, tooj liab, hlau, gallium, mercury, propane, lanthanum, magnesium, manganese, nickel, lead, palladium, scandium, thorium, titanium, zinc, zirconium, thiab lwm yam.
Ntim thiab Xa Khoom
25KG / Nruas los yog 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.
