Isheke lokuhlola indawo ye-Jiangsu Province: 20% yeCopper Alloy Taps idlula ukuhola

Okokugeza ubuso, ukupheka, namanzi abilayo, izakhamizi azikwazi ukwenza ngaphandle kwamanzi kampompi nsuku zonke, kanye nompompi. Phambili, kwaba nemibiko yokuthi kunezinkinga ezengeziwe zomthofu ompompini, okungase kubangele ukulimala emzimbeni womuntu. NgoMeyi walo nyaka, inguqulo entsha yezinga likazwelonke lompompi likhishwe ngokusemthethweni futhi lizoqala ukusebenza ngokusemthethweni kusukela ngenyanga ezayo. Izinga elisha likazwelonke licacisa umkhawulo wemvula yomthofu.

Izolo, i-Quality Supervision Bureau yesiFundazwe sase-Jiangsu yenze ukuhlola nokuqapha ubungozi kompompi basemakethe yase-Jiangsu nasezindaweni zokukhiqiza ngokuvumelana namazinga kazwelonke amanje kanye namazinga amasha kazwelonke.. Ngenxa yalokho, 20% yemvula eholayo yompompi bengxubevange yethusi yeqe umkhawulo wezinga elisha lezwe.

Umthofu oweqile ne-chromium

Kusukela ngoDisemba, ukukhiqizwa kwemikhiqizo eyeqa izinga kuzojeziswa

Esikhathini esedlule, wawungekho umkhawulo oyisibopho enanini lezinto ezingcolisa umoya ezinqwabeleka kompompi. Izinga likazwelonke elisha lizosebenzisa izindlela zokutholwa kanye namazinga omkhawulo we-United States. Ding Hongliu, umqondisi wehhovisi eliphathekayo nelamakhemikhali leSuzhou City Product Quality Supervision and Inspection Institute, uthe ukuqapha ubungozi kugxile kakhulu kompompi bengxube ye-copper alloy kanye nompompi bensimbi engagqwali abasetshenziswa abahlali nsuku zonke., futhi kugxilwe enkingeni yomthofu kanye nemvula ye-chromium kompompi abathengi abakhathazeke kakhulu ngayo. qapha.

Izinga elisha likazwelonke libeka ukuthi inani lemvula yomthofu kumafaucethi alikho ngaphezu kuka-5μg/l, kodwa phakathi 53 ompompi abathi ama-alloys ethusi, 11 amaqoqo omthofu adlula izinga, okwedlula 20% kwengqikithi. “Isizathu esiyinhloko ukuthi izinkampani eziningi zokukhiqiza zikhetha ukucubungula ithusi, ama-alloys ethusi, futhi usebenzise nethusi eligaywe kabusha njengethusi elingukhiye, ithangi lamanzi emoto yethusi, njll.” UDing Hongliu ukhumbuze ukuthi inani lemvula yomthofu libhekisa ku- 16 amahora okuxhumana phakathi kwamanzi nodonga lwangaphakathi lwempompi Inani lemvula, ngakho-ke amanzi ashiywe kumpompi isikhathi eside ayakhishwa ngesikhathi sokusetshenziswa, okunganciphisa ngempumelelo ingozi yokuphepha.

Izinga elisha likazwelonke liphinde libeke ukuthi inani lemvula ye-chromium alikho ngaphezu kuka-10.0μg/l, kodwa ekuhlolweni, kusekhona amaqoqo amabili ompompi abedlula izinga. Kunezizathu ezimbili zemvula eningi ye-chromium. Enye imvula eyinsalela ye-chromium kumthungo wokushisela kanye ne-surface coating., kanti enye iwukuthi umpompi ngokwawo uqukethe i-chromium, eliwa ngesikhathi sokucwiliswa.

Nokho, umnyango wamanje wokugada ikhwalithi uthole izinkinga ngale mikhiqizo, kodwa ayikwazi ukufaka izinhlawulo enkampanini. UDing Hongliu wethule lokho kusukela ngenyanga ezayo, inqobo nje uma impompi idethi yayo yokukhiqiza ingemuva komhla ka-1 Disemba itholwa ukuthi yeqa izinga, ingajeziswa. Gu Yonghua, isekela lomqondisi woMnyango Wezokuqondisa Nokwengamela Ikhwalithi Yesifundazwe sase-Jiangsu, uthe uMnyango obhekele izinga lekhwalithi unikeza izexwayiso ngengozi kulezi zinkampani ezibone izinkinga futhi uzicela ukuthi zisheshe zilungise.

ezinye izinkinga

Ingabe insimbi engagqwali nokugqwala?

Kulesi sivivinyo, iqoqo elilodwa lompompi bensimbi engagqwali empeleni babonisa izimpawu zezindawo ezinkulu zokugqwala ngemva kokuhlolwa. Ngokusho kukaWang Xiaopeng, umhloli Wehhovisi Lokuhlola Ifenisha Nokuhlobisa leSuzhou Product Quality Supervision and Inspection Institute., uma ifilimu ye-oxide ebusweni bompompi wensimbi engagqwali ingaphathwa kahle, ukugqwala kuzokwenzeka.

Insimbi engagqwali ingase igle. Kuthiwani ngesimo semibhobho ye-copper alloy? Imiphumela yokuhlolwa ikhombisa lokho 47.2% kwe 53 amaqoqo ompompi bengxube ye-copper ahluleka ukuhlangabezana nezidingo. Bangu 25 amaqoqo, okuyinto ekhathaza nakakhulu.

I-Zinc alloy izenza ingxube yethusi

Ezingeni elisha likazwelonke elizosetshenziswa, kubekwe ngokucacile ukuthi i-zinc alloy materials akufanele isetshenziswe ezingxenyeni zikampompi ezithintana namanzi ngokuqondile.. Nokho, ngesikhathi sokuhlolwa, ochwepheshe bathole ukuthi kusekhona isimangaliso sokusebenzisa ompompi bengxube ye-zinc ukuzenza ompompi bengxube yethusi emakethe.. Phakathi kwe 53 amaqoqo ompompi okuthiwa ama-alloys ethusi, 9 amaqoqwana ayengawomgunyathi anezinhlayiya ze-zinc.

U-Wang Xiaopeng uthe lapho abathengi bethenga, kunendlela encane yokwenza umehluko. Udonga lwangaphakathi lwemikhiqizo ye-alloy yethusi ngokuvamile alusicaba kakhulu, kuyilapho udonga lwangaphakathi lwe-zinc alloy lubushelelezi kakhulu, futhi udonga lwangaphakathi lunemigqa ehlukanisayo esobala.

khumbuza

Ungabi nobugovu

Imiphumela yokuhlolwa ibonisa ukuthi cishe bonke ompompi abanenkinga kulokhu bagxile ngezansi 300 yuan. Okwamanje, ithani lethusi elihlanzekile libiza ngaphezu 68,000 yuan, kanti umpompi usebenzisa cishe u-500g wethusi. Izindleko zethusi cishe 34 yuan, futhi izindleko zokukhiqiza ngeke zibe ngaphansi 100 yuan. Ngakho-ke, kukhona izinkinga ezinkulu izinga enamathela surface kanye kwezulu umthofu nge 30 ku 40 i-yuan faucet emakethe.
