Umpompi wensimbi osindayo owedlulele

Imikhiqizo yenhlanzeko ihlobene nempilo nokuphepha kwabantu. Okwamanje, ukuthuthukiswa kwemboni yasekhaya yezimpahla zenhlanzeko akujwayelekile kakhulu. Kusenegebe elikhulu kubuchwepheshe besimanje bokukhucululwa kwendle uma kuqhathaniswa namazwe asethuthukile njengaseYurophu nase-United States. Izinga nokuphepha kwemikhiqizo yezindlu zangasese akwanele ngokusobala.

I-Promei faucet hexavalent chromium idlula izinga leminyaka emibili elandelanayo kuhlu olumnyama lwekhwalithi

Ku 2013, i-Shanghai Municipal Bureau of Quality Supervision yenze ukugada okukhethekile kanye nokuhlola ikhwalithi yompompi abakhiqizwa futhi bathengiswa e-Shanghai.. Uphawu lokuhweba olukhiqizwe yi-Zhuhai Pulemei Kitchen and Bath Co., Ltd. nguPulemei, futhi imodeli yokucaciswa yi-DN15 isibambo esisodwa sokulawula okukabili 70101G, umpompi wasekhishini onedethi yokukhiqiza noma inombolo yenqwaba 2013-1-15, kutholwe ukuthi yeqa izinga le-chromium (i-chromium ene-hexavalent) okuqukethwe, futhi ukunemba kwentambo yepayipi kutholwe njengokungafaneleki, ngoba izinkomba ezimbili bezingafaneleki, yayimakwe ngokukhethekile ngokuthi ” Inkinga yekhwalithi ibucayi”.

I-Shanghai Municipal Bureau of Quality Supervision isho esazisweni ukuthi i-chromium (i-chromium ene-hexavalent) iphrojekthi ihlole inani le-chromium ene-hexavalent emkhiqizweni ocwiliswa amanzi. Ukungena kwe-chromium eyi-hexavalent kungase kubangele ukujiya kolwelwesi lomlomo, isicanucanu, ubuhlungu obukhulu besisu nesibindi Ukuvuvukala, okuhambisana nezimpawu ezinjengokuphelelwa umoya, izinga lokushaya kwenhliziyo, namajaqamba enyama, ibeka impilo yomuntu engozini. Ukuhlolwa kokunemba kochungechunge lwepayipi kuyikhwalithi yokunemba kochungechunge. Ukwehluleka kwale nto kungase kubangele ukuthi umkhiqizo uvuze amanzi noma uqhume isixhumi esibonakalayo.

Ngemva konyaka, ekugadweni okukhethekile kanye nokuhlola indawo okwenziwa yi-Shanghai Municipal Bureau of Quality Supervision in 2014, I-Zhuhai Promet iphinde yatholakala ine-chromium eyeqile (i-chromium ene-hexavalent) okuqukethwe. Ngo-Agasti 18, i-Shanghai Municipal Bureau of Quality Supervision ikhiphe i- “2014 I-Shanghai Water Tap Product Quality Supervision Spot Check Results”, eyayibonisa ukuthi umenzi (okuzisholo) kuyinto “Ikhishi le-Zhuhai Pulemei & I-Bath Co., Ltd.” kanye nophawu lokuhweba ” Umpompi wasekhishini onemodeli yokucaciswa kwe “I-DN15, 70118A”, idethi yokukhiqiza noma inombolo yenqwaba ye “2013-11-15” yahlulelwa njengomkhiqizo osezingeni eliphansi ngenxa ye-chromium eningi (i-chromium ene-hexavalent).

I-chromium ene-carcinogen hexavalent etholwe kumpompi idlula izinga futhi iyingozi empilweni.

I-Promei ibilokhu ikhangiswa njenge “uhlobo oluhamba phambili emhlabeni lwempahla yensimbi engagqwali”, futhi sekuyisikhathi eside ekhuthazwa “zero lead impilo” njengendawo yayo yokuthengisa. Eminyakeni emibili, kuyashaqisa ngempela ukutholwa kabili ngokulandelana ukuthi okuqukethwe kwe-chromium (i-chromium ene-hexavalent) idlula izinga. I-Chromium iyingxenye yensimbi emhlophe enezimo ezimbili ze-valence, okuyi-trivalent chromium ne-hexavalent chromium. I-trivalent chromium ayinabungozi kubantu, kodwa ngaphansi kwezimo ezithile, i-chromium ene-hexavalent ekhiqizwa ngemva kwe-oxidation iyi-carcinogen eyingozi kubantu. Ngokusho kongoti bezimboni, uma ukunemba kwentambo yepayipi okungafanelekile kuthinta kuphela ukusebenza komkhiqizo, bese kuba i-chromium eyeqile (i-chromium ene-hexavalent) kungase kubeke engozini impilo yabantu.

Yinkampani enjalo nje ye-sanitary ware ekhuthaza ngamandla “zero-lead impilo” futhi igcizelela ukuthi imikhiqizo yayo ayinawo umthofu. Kutholwe ngokuphindaphindiwe ukuthi okuqukethwe kwe-chromium (i-chromium ene-hexavalent) idlula izinga, okubonisa ukushiyeka kwenqubo yokuqapha izinga lomkhiqizo wayo.

I-Stainless steel faucet ayiyona “ziro lead” Ukukhangisa kohlangothi olulodwa lwe-Promet kudukisa ukusetshenziswa

Kanye, isici esikhulu senkulumo-ze yebhizinisi ukukhuthaza uhlangothi olulodwa ukuthi inkomba eyodwa ifanelekile, ngenkathi uziba noma ukhipha ezinye izinkomba. Nokulinganisa ukuthi umpompi ufanelekile yini, inani lemvula yomthofu lingenye yezici. Kukhona ezinye izinsimbi emkhiqizweni, kanye nokulawula okungalungile kungase kubangele ukulimala emzimbeni womuntu.

Muva nje, ngesikhathi abasebenzi baseChina Quality Miles bevakashele izitolo zezinto zokwakha zasekhaya eBeijing, bathola ukuthi isikhangiso esikhulu sePromite “0 Ukuhola okuholayo” futhi “0 Impilo Eholayo” yayidonsa amehlo kakhulu. Ngakho, umpompi wensimbi engagqwali ngempela “ziro lead”? Yeka ukuthi kuyiqiniso kangakanani ngemuva kwe-hype?

Ngaphambi kwalokhu, Ama-CCTV “Ingabe Ngempela” Uhlelo lwenze izivivinyo zesampula 14 ompompi brand. Imiphumela yesampula yabonisa ukuthi wonke amapayipi aqukethe umthofu. I-National Building Materials Industry Construction Hardware Plumbing Products Quality Supervision and Inspection Centre inesibopho salokhu kuhlola.. Ukuhlolwa kusekelwe ku-JC/T1043-2007 “Umkhawulo Wokukhishwa Komthofu Ovela Kumpompi Wamanzi”. Leli zinga libeka ukuthi inani lomthofu ophuma kompompi bamanzi lingakanani 11 micrograms/litre. Ngokwaleli zinga, ukuqapha umpompi kudinga ukugezwa, ocwile for 19 izinsuku zokulingisa amanzi asekhaya, thatha amasampula amanzi ngezikhathi ezahlukene, futhi ihlaziye ngamakhemikhali inani lemvula yomthofu. Ngemva 21 izinsuku zokuhlolwa, imiphumela yokuhlolwa yabonisa ukuthi 14 ompompi bemikhiqizo abathunyelwe ukuthi bayohlolwa baqukethe umthofu, kanye nenani lemvula yomthofu kompompi bensimbi engagqwali ngempela laliphansi kunalelo lompompi bethusi. Kodwa akukhona ukuthi ompompi bensimbi engagqwali abanawo umthofu. I “ziro lead” okukhuthazwa ngamabhizinisi afana ne-Promax ayihambisani neqiniso. Kungumbono nje webhizinisi.

Ngokusho kwabangaphakathi embonini, ngomqondo oqinile, insimbi engagqwali nayo iqukethe umthofu, kodwa iwumthofu ophansi. Akusho ukuthi impahla ayinawo umthofu. Insimbi engagqwali ayinawo umthofu. Amapayipi angaphakathi kumpompi wensimbi engagqwali, indandatho yerabha yepulasitiki, futhi ipulasitiki yomlomo wensimbi nayo iqukethe umthofu. ukuhola. Inkinga enkulu ngensimbi engagqwali ukuthi izinsimbi ezisindayo zidlula izinga. Ngaphandle kokuhola, izinsimbi ezisindayo ngokweqile ziyethusa kakhulu. Ikhwalithi ebanzi yemikhiqizo kampompi wasekhishini idinga ukulawula okuqinile kokuqukethwe komthofu nezinye izinto ezifana ne-chromium, manganese, i-arsenic, njll., okungase kulimaze impilo yabantu. Ochwepheshe bezimboni bakhumbuza ukuthi abathengi akudingeki balandele ngokungaboni “ziro lead” lapho uthenga ompompi, futhi amabhizinisi anesibopho sokuhlinzeka abathengi ngolwazi oluphelele kanye nenhloso, esikhundleni sokumemezela uhlangothi olulodwa okuyihaba nokusetshenziswa okudukisayo.

Ukwethulwa kwezinga elisha likazwelonke kuzonqanda ngempumelelo isimo sezinsimbi ezisindayo ngokweqile kompompi.

Kubikwa ukuthi izinga elisha likazwelonke “I-Ceramic Sheet Sealing Faucet” iqale ukusebenza ngokusemthethweni ngoDisemba 1, 2014. Phakathi kwazo, umpompi wempompi wensimbi esindayo, ukusebenza kokuvala, izinga lokugeleza, futhi ukuphila kuyimigomo eyisibopho, futhi ngokokuqala ngqa kuyisibopho ukuthi inani lezibalo lemvula yomthofu kumpompi akufanele libe likhulu kune 5 micrograms/litre. Izinga likazwelonke elisha linyusa izigaba zokutholwa kokuqukethwe kwensimbi kompompi ukuze 17 izinhlobo. Ngaphezu kokuhola, 16 okuqukethwe kwensimbi okufana ne-chromium ne-manganese kufakwe ezintweni ezibalulekile zokutholwa. Izindinganiso ezilinganiselwe zokungcola kwensimbi zizohambisana nezindinganiso zaseYurophu nezaseMelika.

Ngemva kokuqaliswa kwezinga likazwelonke elisha, ukubukeka kanye nekhwalithi yompompi emakethe kulindeleke ukuthi kuthuthukiswe, futhi ingakhuthaza amabhizinisi ukuqinisa ukuphathwa nokuthuthukiswa kwemikhiqizo, okuzodlala indima ebalulekile ekusebenzeni okujwayelekile kwayo yonke imakethe yezimpahla zenhlanzeko futhi kwenze imboni yezimpompi zaseChina ibe igxathu eliya phambili Izindinganiso zamazwe ngamazwe, kanye nezinxushunxushu zezinsimbi ezisindayo ngokweqile kompompi basekhaya nazo zizonqandwa ngempumelelo.
