Pob tshab iav Mug, iav lub raj mis Extractable Heavy Hlau,

Heavy hlau migration Test

Txoj kev: Kev npaj ua piv txwv hauv 3% acetic acid (w / v) hauv cov tshuaj aqueous ntawm 40 ℃ rau 2 teev nrog siv rau EN1310-1: 2004 rau kev xaiv cov qauv kev sim, ua raws li kev tshuaj ntsuam xyuas siv Inductively Coupled Argon Plasma Spectrometry (ICP), Inductively coupled Plasma – mass spectrometry (ICP-MS) thiab Ion Chromatography (IC) (3rd migration)
Cov khoom xeem: Tshwj xeeb Migration ntawm Antimony; Kev tsiv teb tsaws chaw tshwj xeeb ntawm arsenic; Tshwj xeeb tsiv teb tsaws ntawm Barium; Kev tsiv teb tsaws chaw tshwj xeeb ntawm Boron; Kev tsiv teb tsaws chaw tshwj xeeb ntawm Cadmium; Tshwj xeeb tsiv teb tsaws ntawm Cerium; Tshwj xeeb tsiv teb tsaws ntawm Chromium; Tshwj xeeb tsiv teb tsaws ntawm Cobalt; Kev tsiv teb tsaws chaw tshwj xeeb; Kev tsiv teb tsaws chaw tshwj xeeb; Kev tsiv teb tsaws tshwj xeeb ntawm Manganese; Tshwj xeeb tsiv teb tsaws ntawm Nickel; Tshwj xeeb tsiv teb tsaws ntawm Rubidium; Tshwj xeeb tsiv teb tsaws ntawm Zirconium .

• Cov iav iav: quartz xuab zeb 50% -60%, soda tshauv 30%, tawg iav 10%, kev ua tus neeg sawv cev <0.1%, toner cartridge hmoov <0.1%.
  Nws tuaj yeem pom los ntawm cov khoom saum toj no uas lub ntsiab ntawm iav yog quartz xuab zeb, thiab lub ntsiab ntawm quartz xuab zeb yog silica thiab impurities.
  Qhov no txhais tau hais tias ntev npaum li cov impurities hauv quartz xuab zeb tsis muaj cov hlau hnyav, cov iav uas ua los ntawm quartz xuab zeb yog dawb ntawm cov hlau hnyav.
• Cov pa phem ntawm quartz xuab zeb feem ntau yog los ntawm cov dej paug hauv dej (dej, dej nag, thiab lwm yam) thiab kuv qhov chaw muaj kuab paug.
• Cov xwm txheej tam sim no ntawm cov pa phem hauv thaj chaw mine: Tam sim no, nyob rau hauv Suav teb, kev ua cov pob zeb mining yuav tsum tau kev pom zoo thiab daim ntawv tso cai los ntawm National Development and Reform Commission los tshuaj xyuas thaj chaw mine. Minerals ze rau qhov chaw dej yog txwv tsis pub tshaj tawm los ntawm kev tso cai tso cai thiab mining. Yog li ntawd, kev ua lag luam tsis raug cai tau ploj mus tag nrho hauv Suav teb. xyoo. Yog li ntawd, tsis muaj kuab paug ntawm kuv qhov chaw txhua.
• Cov xwm txheej tam sim no ntawm cov dej muaj kuab paug nrog dej muaj kuab paug: Tuam Tshoj txoj cai tiv thaiv ib puag ncig tau txwv tsis pub tsim cov chav dej, tsiaj txhu cwj mem, tso quav, dej phwj tuaj lossis pov tseg hauv qhov deb ntawm 50 meters los ntawm qhov chaw dej (xws li dej ntws thiab qhov dej) lossis hauv 30 meters. raws ntug dej hiav txwv ntawm qhov chaw dej. , tsis txhob tsuag tshuaj tua kab, thiab lwm yam nyob ze ntawm qhov chaw dej. Kev ua haujlwm tsuas yog txwv tsis pub nyob hauv qhov chaw tiv thaiv dej. (Cov cheeb tsam ntawm thaj chaw tiv thaiv dej: thaj chaw dej hauv qab ntawm txoj kab nce siab sib haum rau ntau xyoo nruab nrab cov dej hauv ib lub vojvoog ntawm 500 meters los ntawm cov dej nkag ntawm lub reservoir. Qhov chaw ntawm thaj chaw dej: 0.25 square kilometers.)
• Cov xwm txheej quo ntawm cov pa phem los ntawm kev lag luam: Thaum ntau tus neeg xa khoom tsis tuaj yeem xa tuaj raws sijhawm, lawv yuav ib txwm hais tias “kev tshuaj xyuas ib puag ncig kev tiv thaiv, cov tsev tsis raug cai, thiab cov chaw tua hluav taws”. Tuam Tshoj tau kaw kaum tawm txhiab lub tuam txhab ua kuab paug (xws li tsiaj yug tsiaj, thiab cov quav ncaj qha tsis ua kom tsis muaj menyuam). Cov emissions kuj suav hais tias ua rau cov lag luam ua paug). Tom qab xyoo ntawm kev tshuaj xyuas los ntawm pawg neeg tiv thaiv ib puag ncig hauv nruab nrab, tam sim no, emissions ntawm cov lag luam tseem muaj sia nyob yog tag nrho cov qauv thiab tsis muaj teeb meem rau ib puag ncig.
• Yog li ntawd, ob qho tib si dej hauv av thiab qhov chaw ua kuab paug tau raug tshem tawm, thiab cov hlau hnyav tsis tuaj yeem tshawb pom los ntawm cov khoom mus rau kev tsim khoom.
• Nws kuj yog vim li no tias Suav iav tau suav nrog hauv cov khoom tsis raug tshuaj xyuas.

Ntev npaum li koj txaus siab them tus nqi xeem, qhov kev kuaj xyuas qhov hnyav no tuaj yeem ua tiav ntawm lub siab nyiam, txawm tias hom iav lub raj mis lossis khob, tsuav yog muab los ntawm peb, nws tuaj yeem dhau.
