Product Description:
Dawb crystalline hmoov.Soluble nyob rau hauv dej thiab muaj peev xwm chelate nrog ntau yam hlau ions.
Daim ntawv thov:
(1) Ntawm cov ntsev ntawm EDTA, cov ntsev disodium yog qhov tseem ceeb tshaj plaws thiab yog ib qho tseem ceeb ntawm tus neeg sawv cev rau kev sib xyaw ntawm cov hlau ions thiab cov hlau sib cais, tab sis kuj yog cov tshuaj ntxuav tes, kua xab npum, tshuaj zawv plaub hau, tshuaj tua kab mob, tshuaj tua kab mob thiab kho cov kev daws teeb meem. Kev loj hlob thiab kev ua cov ntaub ntawv xim-sensitive, dej purification agents, pH adjusters, anionic coagulants, thiab lwm yam. Nyob rau hauv lub redox pib system rau lub polymerization ntawm styrene-butadiene roj hmab, disodium EDTA yog siv los ua ib feem ntawm cov active neeg sawv cev, feem ntau yog complexing. ferrous ions thiab tswj tus nqi ntawm cov tshuaj tiv thaiv polymerization.Nws tsis muaj tshuaj lom, nrog rau qhov ncauj LD50 ntawm 2000 mg / kg hauv nas.Siv los ua tus neeg sawv cev chelate rau hlau ions.
(2) Tshuaj xyuas cov calcium, magnesium, thiab lwm yam. Siv rau hauv kev lag luam tshuaj, kev tsim xim, smelting ntawm cov hlau tsis tshua muaj, thiab lwm yam. Nws yog ib qho tseem ceeb complexing tus neeg sawv cev thiab hlau npog tus neeg sawv cev.
(3) Siv los ua ammonia carboxylate complexing tus neeg saib xyuas rau kev txiav txim siab ntawm calcium, magnesium thiab lwm yam hlau.Siv los ua tus neeg sawv cev npog hlau thiab xim tsim tawm.Kuj tseem siv nyob rau hauv kev lag luam kws tshuaj thiab hauv smelting ntawm tsawg hlau.
(4) Nws kuj yog siv los ua antioxidant synergist hauv cov tshuaj pleev ib ce thiab yog cov hlau ion chelating tus neeg sawv cev, uas muaj cov nyhuv tib yam li E DTA, tab sis muaj ntau yam kev siv.Nws tuaj yeem siv rau hauv cov khoom siv tshuaj pleev ib ce uas muaj cov kab hlau ions thiab hauv kev tsim khoom thiab khaws cia thiab kev thauj mus los ntawm cov tshuaj pleev ib ce uas cov thawv hlau siv.
Pob:25 kgs / hnab los yog raws li koj thov.
Cia:Khaws ntawm qhov chaw ventilated, qhuav.
