Jiangsu Province Hunhu Kuongorora Spot Cheki: 20% yemhangura towloy mateki anodarika kutungamira

Yekugeza kumeso, kubika, nemvura inofashaira, vagari vemo havagone kuita pasina pombi yemvura mazuva ese, pamwe chete nepombi. Kare, pakanga pane mishumo yokuti kwakanga kune zvinetso zvakawanda zvinotungamirira-mutobvu mumapombi, izvo zvinogona kukuvadza muviri wemunhu. Muna May wegore rino, iyo vhezheni itsva yemhando yenyika yepombi yakaburitswa zviri pamutemo uye ichaitwa zviri pamutemo kubva mwedzi unouya. Chiyero chitsva chenyika chinotsanangura muganhu wekunaya kwemutobvu.

Nezuro, iyo Quality Supervision Bureau yeJiangsu Province yakaita macheki enzvimbo uye yekutarisa njodzi pamapombi mumusika weJiangsu nenzvimbo dzekugadzira zvinoenderana neazvino nyika zviyero uye mitsva yenyika.. Semagumo, 20% yekunaya kwelead yecopper alloy taps yakapfuura muganhu wemwero mutsva wenyika.

Yakawandisa lead uye chromium

Kutanga muna December, kugadzirwa kwezvinhu zvinodarika mwero kucharangwa

Kare, pakanga pasina muganhu unosungirwa pahuwandu hwezvinosvibisa zvakanaya mumapombi. Iyo nyowani yenyika chiyero ichakwevera panzira dzekuona uye kudzikamisa zviyero zveUnited States. Ding Hongliu, director wehofisi yemuviri uye yemakemikari yeSuzhou Guta Chigadzirwa Hunhu Hwekutarisa uye Inspection Institute, akataura kuti kutariswa kwenjodzi kwainyanya kutariswa pamapombi emhangura alloy uye mapombi esimbi asina tsvina anoshandiswa nevagari mazuva ese., uye yakatarisa padambudziko remutobvu uye kunaya kwechromium mumapombi ayo vatengi vanonyanya kunetseka nawo.. monitor.

Muyero mutsva wenyika unotaura kuti kuwanda kwekunaya kwemutobvu mumapombi hakupfuuri 5μg/l., asi pakati 53 pombi dzinoti alloys yemhangura, 11 mabhechi emutobvu anopfuura mwero, kudarika 20% yezvese. “Chikonzero chikuru ndechekuti mazhinji emakambani ekugadzira anosarudza kugadzira mhangura, akakanda alloys emhangura, uye kutoshandisa ndarira yakadzokororwa senge kiyi mhangura, mota yemvura tangi mhangura, etc.” Ding Hongliu akayeuchidza kuti huwandu hwekunaya kwemutobvu hunoreva iyo 16 maawa ekubatana pakati pemvura nemadziro emukati epombi Kuwanda kwekunaya, saka mvura yakasara mupombi kwenguva yakareba inoburitswa panguva yekushandiswa, iyo inogona kunyatso kudzikisa njodzi yekuchengetedza.

Chiyero chitsva chenyika chinotiwo kuwanda kwekunaya kwechromium hakupfuuri 10.0μg/l., asi mukuedzwa, kuchine mabache maviri epombi anodarika mwero. Pane zvikonzero zviviri zvekunaya kwakanyanya kwechromium. Imwe ndiyo yasara kunaya kwechromium mumusono wewelding uye nekunamira kwepamusoro., uye imwe yacho ndeyekuti iyo pombi pachayo ine chromium, iyo inonaya panguva yekunyudzwa.

Zvisinei, dhipatimendi rinoona nezvemhando yepamusoro raona matambudziko nezvigadzirwa izvi, asi haikwanise kupa zvirango pakambani. Ding Hongliu akazivisa izvozvo kutanga mwedzi unouya, chero bedzi iyo faucet ine zuva rekugadzira iri mushure meZvita 1 ichionekwa kuti inopfuura mwero, inogona kurangwa. Gu Yonghua, mutevedzeri wemukuru weJiangsu Provincial Quality Supervision and Supervision department, akati bazi rinoona nezvemhando yepamusoro riri kupa yambiro yenjodzi kumakambani aya anenge aona matambudziko nekuvakumbira kuti vakurumidze kugadzirisa zvinhu..

Will Stainless simbi ichaita ngura?

Mumuedzo uyu, batch rimwe remapombi esimbi isina tsvina yakanyatsoratidza zviratidzo zvenzvimbo dzakakura dzekuora mushure mebvunzo. Maererano naWang Xiaopeng, inspector weFenicha uye Decoration Inspection Hofisi yeSuzhou Chigadzirwa Hunhu Chekutarisa uye Inspection Institute., kana iyo oxide firimu iri pamusoro pepombi yesimbi isina kubatwa isina kubatwa zvakanaka, ngura ichaitika.

Simbi isina tsvina inogona kuve nemarara. Zvakadini nemamiriro ezvinhu emhangura alloy faucets? Miedzo yabuda inoratidza izvozvo 47.2% ye 53 mabhechi emhangura alloy faucets anotadza kuzadzisa zvinodiwa. Pane 25 Batch, zvinova zvinotonyanya kunetsa.

Zinc alloy inonyepedzera kunge copper alloy

Muchipimo chitsva chenyika chichaitwa, zvinonyatsotaurwa kuti zinc alloy zvinhu hazvifanirwe kushandiswa muzvikamu zvepombi zvinosangana nemvura.. Zvisinei, panguva yekuongorora, nyanzvi dzakaona kuti pachine chiitiko chekushandisa zinc alloy faucets kuita kunge mapombi emhangura alloy pamusika.. Pakati pe 53 mabhechi epombi anonzi alloys emhangura, 9 mabhechi aive emanyepo ane zinc alloys.

Wang Xiaopeng akati kana vatengi vanotenga, pane nzira diki yekuita mutsauko. Rusvingo rwemukati rwezvigadzirwa zvemhangura alloy kazhinji haruna kunyanya kutsetseka, nepo mukati memadziro emu zinc alloy yakanyanya kutsetseka, uye rusvingo rwomukati rune mitsetse iri pachena inoparadzanisa.

Usave nemakaro

Mhedzisiro dzebvunzo dzinoratidza kuti dzinenge dzese dzinonetsa matepi panguva ino dzakaiswa pazasi 300 yuan. Parizvino, tani yemhangura yakachena inodhura kupfuura 68,000 yuan, uye pombi inoshandisa 500g yemhangura. Mari yemhangura inenge 34 yuan, uye mutengo wekugadzira hauzove wakaderera pane 100 yuan. Naizvozvo, kune matambudziko makuru mumhando yekupfekedzwa kwepamusoro uye kunaya kwemutobvu ne 30 ku 40 yuan faucet pamusika.
