Tshaj hnyav hlau faucet

Cov khoom siv tu cev muaj feem xyuam rau kev noj qab haus huv thiab kev nyab xeeb ntawm tib neeg. Tam sim no, txoj kev loj hlob ntawm kev lag luam khoom noj khoom haus hauv tsev tsis yog tus qauv zoo heev. Tseem muaj qhov sib txawv loj hauv cov cuab yeej huv huv niaj hnub piv nrog cov teb chaws tsim kho xws li Europe thiab Tebchaws Meskas. Qhov zoo thiab kev nyab xeeb ntawm cov khoom siv huv hauv tsev yog pom tseeb tsis txaus.

Promei faucet hexavalent chromium tshaj tus qauv rau ob xyoos sib law liag ntawm cov npe dub zoo

Hauv 2013, Shanghai Municipal Bureau of Quality Supervision tau ua kev saib xyuas tshwj xeeb thiab kuaj xyuas qhov zoo ntawm cov faucets uas tsim thiab muag hauv Shanghai. Lub cim lag luam tsim los ntawm Zhuhai Pulemei Chav Ua Noj thiab Da Dej Co., Ltd. yog Pulemei, thiab tus qauv specification yog DN15 ib leeg kov dual tswj 70101G, chav ua noj faucet nrog hnub tsim khoom lossis batch tooj 2013-1-15, tau kuaj pom kom dhau tus qauv ntawm chromium (hexavalent chromium) cov ntsiab lus, thiab cov yeeb nkab xov raug raug kuaj pom tias tsis tsim nyog, vim tias ob qhov ntsuas tsis tsim nyog, nws tau tshwj xeeb cim raws li ” Qhov teeb meem zoo yog qhov loj”.

Lub Tsev Haujlwm Saib Xyuas Kev Ua Haujlwm Hauv Nroog Shanghai tau hais hauv kev ceeb toom tias chromium (hexavalent chromium) qhov project tau sim tus nqi ntawm hexavalent chromium precipitated nyob rau hauv cov khoom soaking dej. Kev noj cov tshuaj hexavalent chromium tuaj yeem ua rau thickening ntawm qhov ncauj mucosa, xeev siab, mob plab heev thiab daim siab o, nrog rau cov tsos mob xws li ua tsis taus pa, mem tes, thiab nqaij cramps, mob hnyav heev rau tib neeg kev noj qab haus huv. Yeeb nkab xov precision tshuaj xyuas yog cov xov precision zoo. Kev ua tsis tiav ntawm cov khoom no tuaj yeem ua rau cov khoom xau dej los yog cuam tshuam cuam tshuam.

Ib xyoos tom qab, nyob rau hauv kev saib xyuas tshwj xeeb thiab chaw kuaj xyuas los ntawm Shanghai Municipal Bureau of Quality Supervision hauv 2014, Zhuhai Promet tau pom dua tias muaj chromium ntau dhau (hexavalent chromium) cov ntsiab lus. Lub Yim Hli 18, Shanghai Municipal Bureau of Quality Supervision tau tshaj tawm “2014 Shanghai Dej Kais Khoom Zoo Saib Xyuas Qhov Chaw Tshawb Xyuas”, uas qhia tias tus neeg tsim khoom (npe) yog “Zhuhai Pulemei Chav Ua Noj & Bath Co., Ltd.” thiab lub cim lag luam yog ” Chav ua noj faucet nrog tus qauv specification ntawm “DN15, 70118A”, hnub tsim khoom lossis batch naj npawb ntawm “2013-11-15” raug txiav txim raws li cov khoom lag luam tsis zoo vim yog chromium ntau dhau (hexavalent chromium).

Cov carcinogen hexavalent chromium kuaj pom nyob rau hauv lub faucet tshaj tus qauv thiab muaj teeb meem rau kev noj qab haus huv

Promei ib txwm tau tshaj tawm raws li “lub ntiaj teb ua lag luam ntawm stainless hlau huv ware”, thiab tau txhawb nqa ntev “xoom lead noj qab haus huv” raws li nws qhov muag. Hauv ob xyoos, Nws yog qhov txaus ntshai heev uas tau kuaj pom ob zaug ua ke uas cov ntsiab lus ntawm chromium (hexavalent chromium) tshaj tus qauv. Chromium yog cov hlau dawb nrog ob lub xeev valence, xws li trivalent chromium thiab hexavalent chromium. Trivalent chromium tsis muaj teeb meem rau tib neeg, tab sis nyob rau hauv tej yam xwm txheej, hexavalent chromium uas tsim tom qab oxidation yog cov carcinogen uas tsim kev puas tsuaj rau tib neeg. Raws li cov kws tshaj lij kev lag luam, yog tias tsis tsim nyog cov yeeb nkab xov raug tsuas yog cuam tshuam cov khoom lag luam, tom qab ntawd dhau chromium (hexavalent chromium) tuaj yeem ua rau muaj kev phom sij rau tib neeg.

Nws tsuas yog xws li lub tuam txhab huv huv uas txhawb nqa “xoom-lead noj qab haus huv” thiab hais tias nws cov khoom tsis muaj txhuas. Nws tau rov kuaj pom tias cov ntsiab lus ntawm chromium (hexavalent chromium) tshaj tus qauv, uas qhia tau hais tias qhov tsis txaus ntawm nws cov khoom zoo saib xyuas cov txheej txheem.

Stainless hlau faucet tsis yog “xoom lead” Promet qhov kev tshaj tawm ib leeg ua rau kev siv tsis raug

Txhua sab nrog, ib qho tseem ceeb ntawm kev tshaj tawm kev lag luam yog kev txhawb nqa ib sab uas ib qho qhia tau tsim nyog, thaum tsis quav ntsej lossis tshem tawm lwm qhov ntsuas. Thiab ntsuas seb lub faucet puas tsim nyog, tus nqi ntawm cov hmoov txhuas los nag tsuas yog ib qho ntawm cov xwm txheej xwb. Muaj lwm yam hlau hauv cov khoom, thiab kev tswj tsis zoo kuj tseem yuav ua rau muaj kev phom sij rau tib neeg lub cev.

Tsis ntev los no, thaum cov neeg ua haujlwm ntawm Tuam Tshoj Quality Miles tau mus xyuas cov khw muag khoom hauv tsev hauv Beijing, lawv pom tias qhov kev tshaj tawm loj ntawm Promite “0 Lead Lead” thiab “0 Lead Health” yog qhov muag heev. Yog li, yog stainless hlau faucet tiag tiag “xoom lead”? Yuav ua li cas muaj tseeb yog nws qab lub hype?

Ua ntej no, CCTV cov “Puas yog tiag” qhov kev zov me nyuam tau ua cov qauv ntsuas rau 14 hom faucets. Cov txiaj ntsig ntawm kev kuaj pom tau tias tag nrho cov faucets muaj cov hmoov txhuas. National Building Materials Industry Construction Hardware Plumbing Products Quality Supervision and Inspection Center yog lub luag haujlwm rau qhov kev xeem no. Kev xeem yog raws li JC/T1043-2007 “Kev txwv ntawm Lead tso tawm ntawm cov kais dej”. Cov txheej txheem no tau teev tseg tias cov hlau lead tso tawm los ntawm cov kais dej yog 11 micrograms / liter. Raws li tus qauv no, Kev saib xyuas faucet yuav tsum tau muab yaug, soaked rau 19 hnub simulate cov dej hauv tsev, coj cov qauv dej ntawm lub sijhawm sib txawv, thiab tshuaj ntsuam xyuas tus nqi ntawm cov hmoov txhuas los nag. Tom qab 21 hnub xeem, cov kev xeem tau pom tias cov 14 hom faucets xa tuaj rau kev tshuaj xyuas muaj cov hmoov lead, thiab tus nqi ntawm cov hmoov lead los nag hauv stainless hlau faucets yog qhov tseeb qis dua li ntawm tooj liab faucets. Tab sis nws tsis yog tias stainless hlau faucets tsis muaj txhuas. Cov “xoom lead” txhawb nqa unilaterally los ntawm cov lag luam xws li Promax tsis nyob rau hauv txoj kab nrog qhov tseeb. Nws tsuas yog gimmick ntawm kev lag luam.

Raws li kev lag luam insiders, nyob rau hauv ib tug nruj kev xav, stainless hlau kuj muaj txhuas, tab sis nws yog low-lead. Nws tsis tau txhais hais tias cov khoom tsis muaj txhuas. Stainless hlau tsis muaj txhuas. Cov kav dej hauv lub faucet stainless hlau, lub nplhaib roj hmab yas, thiab cov yas ntawm lub qhov ncauj hlau kuj muaj cov hmoov txhuas. coj. Qhov teeb meem loj tshaj plaws nrog cov hlau tsis muaj hlau yog cov hlau hnyav tshaj li tus qauv. Tsuas yog siv lead ua, cov hlau hnyav hnyav dua yog qhov txaus ntshai dua. Qhov zoo ntawm cov khoom siv hauv chav ua noj faucet yuav tsum muaj kev tswj xyuas nruj ntawm cov ntsiab lus txhuas thiab lwm yam khoom xws li chromium., manganese, khoom, lwm., uas yuav ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv. Cov kws tshaj lij kev lag luam ceeb toom tias cov neeg siv khoom tsis tas yuav tsum ua qhov muag tsis pom kev “xoom lead” thaum yuav faucets, thiab cov lag luam yuav tsum tau muab cov ntaub ntawv qhia meej thiab lub hom phiaj rau cov neeg siv khoom, es tsis yog ib sab exaggerated tshaj tawm thiab siv dag ntxias.

Kev taw qhia ntawm tus qauv tshiab hauv lub tebchaws yuav ua rau muaj txiaj ntsig zoo rau qhov tshwm sim ntawm cov hlau hnyav hnyav hauv faucets

Nws tau tshaj tawm tias tus qauv tshiab hauv tebchaws “Ceramic Sheet Sealing Faucet” tau raug coj los siv rau lub Kaum Ob Hlis 1, 2014. Ntawm lawv, lub faucet hnyav hlau nag lossis daus, sealing kev ua tau zoo, tus nqi ntws, thiab lub neej yog cov ntsiab lus uas yuav tsum tau ua, thiab thawj zaug nws yog qhov yuav tsum tau ua kom tus nqi txheeb cais ntawm cov nag lossis daus hauv cov faucet yuav tsum tsis txhob ntau dua. 5 micrograms / liter. Tus txheej txheem tshiab hauv lub tebchaws nce kev tshawb nrhiav cov ntsiab lus ntawm cov hlau hauv faucets rau 17 hom. Ntxiv rau cov hmoov txhuas, 16 cov ntsiab lus hlau xws li chromium thiab manganese muaj nyob rau hauv cov khoom tseem ceeb tshawb nrhiav. Cov qauv txwv rau cov pa phem hlau yuav ua raws li European thiab Asmeskas cov qauv.

Tom qab ua raws li lub teb chaws tus qauv tshiab, cov tsos thiab zoo ntawm faucets nyob rau hauv lub lag luam yuav tsum tau txhim kho, thiab nws tuaj yeem txhawb nqa kev lag luam kom ntxiv dag zog rau kev tswj hwm thiab kev hloov khoom dua tshiab, uas yuav ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm tus qauv ntawm tag nrho cov khoom siv huv huv thiab ua rau Tuam Tshoj txoj kev lag luam faucet ua ib kauj ruam mus rau thoob ntiaj teb cov qauv, thiab kev ntxhov siab ntawm cov hlau hnyav hnyav hauv cov kais dej hauv tsev kuj tseem yuav raug kho kom zoo.
