Kungani isitifiketi se-KTW siyi-"Ipasipoti Yezempilo" Ebalulekile Yezivalo Zenjoloba?—Ukuvula Isihluthulelo Sezimakethe Zomhlaba Wonke Namanzi Okuphuza Aphephile

Isihlokwana: KunganiIzimbonakalisoKumapayipi Akho, Izihlanzi Zamanzi, kanye Nezinhlelo Zokuphayipha Kumele Ube Nale “Passport Yezempilo”

Isitatimende Sabezindaba – (China/Agasti 27, 2025) - Enkathini yokuqwashisa ngezempilo nokuphepha okuphezulu, wonke amaconsi amanzi esiwasebenzisayo ahlolwa ngendlela engakaze ibonwe ohambweni lwawo. Kusukela kumanethiwekhi amakhulu okuphakelwa kwamanzi kamasipala kuya kuma-faucet asekhishini lasekhaya kanye nemishini yokusabalalisa amanzi ehhovisi, ukuqinisekisa ukuphepha kwamanzi “ngebanga lokugcina” kubaluleke kakhulu. Ngaphakathi kwalezi zinhlelo, kukhona umnakekeli ongaziwa kodwa obalulekile—izivalo zerabha. Njengomkhiqizi ohamba phambili emhlabeni jikelele wezivalo zerabha, i-Ningbo Yokey Co., Ltd. ihlola esinye sezitifiketi ezibaluleke kakhulu zokuphepha kwamanzi okuphuza: isitifiketi se-KTW. Lokhu kungaphezu kakhulu kwesitifiketi; kusebenza njengebhuloho elibalulekile elixhumanisa imikhiqizo, ukuphepha, kanye nokwethenjwa.

Isahluko 1: Isingeniso—Umqaphi Ofihliwe Emaphuzwini Okuxhumana
Ngaphambi kokuhlola kabanzi, ake siphendule umbuzo obaluleke kakhulu:

Isahluko 2: Siyini Isitifiketi se-KTW?—Akuyona nje Idokhumenti, Kodwa Ukuzibophezela
I-KTW akuyona indinganiso yamazwe ngamazwe ezimele; kunalokho, iyisitifiketi sezempilo nokuphepha esinegunya elikhulu eJalimane semikhiqizo ehlobene namanzi okuphuza. Igama layo livela ezifinyezweni zezikhungo ezintathu ezinkulu zaseJalimane ezinesibopho sokuhlola nokwamukela izinto ezithinta amanzi okuphuza:

• K: IKomidi Lamakhemikhali Lokuhlolwa Kwezinto Ezisetshenziswayo Ngokuthintana Namanzi Okuphuza (i-Kommission Bewertung von Werkstoffen im Kontakt mit Trinkwasser) ngaphansi kwe-German Gas and Water Association (DVGW).
• T: Ibhodi Lokweluleka Kwezobuchwepheshe Nesayensi (Technisch-Wissenschaftlicher Beirat) ngaphansi kweNhlangano Yamanzi YaseJalimane (DVGW).
• W: Iqembu Elisebenzayo Lamanzi (iWasserarbeitskreis) ngaphansi kwe-German Environmental Agency (UBA).

Namuhla, i-KWT ngokuvamile ibhekisela ohlelweni lokugunyazwa kanye nesitifiketi oluholwa yi-German UBA (Federal Environment Agency) lwazo zonke izinto ezingezona ezensimbi ezithinta amanzi okuphuza, njengerabha, ipulasitiki, izinamathiseli, kanye nezinto zokugcoba. Iziqondiso zayo eziyinhloko yi-KTW Guideline kanye ne-DVGW W270 standard (egxile ekusebenzeni kwe-microbiological).

Kalula nje, isitifiketi se-KTW sisebenza “njengepasipoti yezempilo” yezivalo zerabha (isb., ama-O-rings, ama-gasket, ama-diaphragm), okuqinisekisa ukuthi ngesikhathi sokuxhumana isikhathi eside namanzi okuphuza, azikhiphi izinto eziyingozi, zishintshe ukunambitheka kwamanzi, iphunga lawo, noma umbala wawo, futhi zingavimbela ukukhula kwamagciwane ayingozi.

Isahluko 3: Kungani Isitifiketi se-KTW Sibalulekile Ezimpahleni Zenjoloba?—Izingozi Ezingabonakali, Isiqinisekiso Esibonakalayo
Abathengi abavamile bangase bacabange ukuthi ukuphepha kwamanzi kuthinta amanzi ngokwawo noma izinhlelo zokuhlunga kuphela. Kodwa-ke, ngisho nezivikelo zerabha ezincane kakhulu ezindaweni zokuxhuma, amavalvu, noma izindawo zokuhlangana zingaba yingozi ekuphepheni kwamanzi okuphuza.

1. Ingozi Yokuhlanzwa Kwamakhemikhali: Inqubo yokukhiqiza imikhiqizo yerabha ihilela izithasiselo zamakhemikhali ezahlukahlukene, njengezinto zokupholisa, izinto ezivikela ukungcola, izinto ezilwa nokuvuvukala, kanye nezinto ezifaka imibala. Uma kusetshenziswa izinto ezingezinhle noma izinto ezingafanele, la makhemikhali angase angene emanzini kancane kancane. Ukungenisa izinto ezinjalo isikhathi eside kungaholela ezinkingeni zempilo ezingamahlalakhona.
2. Ingozi Yezimpawu Zokuzizwa Ezishintshile: Irabha engaphansi kwesilinganiso ingase ikhiphe iphunga elibi "lerabha" noma ibangele ukufiphala kanye nokushintsha kombala emanzini, okulimaza kakhulu ulwazi lokuphuza kanye nokuzethemba kwabathengi.
3. Ingozi Yokukhula Kwamagciwane: Izindawo ezithile ezibonakalayo zithambekele ekunamatheleni nasekusabalaleni kwamagciwane, zakha ama-biofilm. Lokhu akugcini nje ngokungcolisa ikhwalithi yamanzi kodwa futhi kungase kube namagciwane (isib. iLegionella) abeka usongo oluqondile empilweni yomphakathi.

Isitifiketi se-KTW sibhekana ngokuqinile nazo zonke lezi zingozi ngochungechunge lwezivivinyo eziqinile. Siqinisekisa ukungangeni kwezinto zokuvala (akukho ukusabela emanzini), ukuzinza (ukusebenza okuqhubekayo ngokusetshenziswa isikhathi eside), kanye nezakhiwo zokulwa namagciwane. Kubakhiqizi abanjengoNingbo Yokey Co., Ltd., ukuthola isitifiketi se-KTW kusho ukuthi imikhiqizo yethu ihlangabezana nezinye zezindinganiso eziphakeme kakhulu zomhlaba wonke zokuphepha emanzini okuphuza—ukuzibophezela okuqinile kumakhasimende ethu nakubathengi bokugcina.

Isahluko 4: Indlela Yokuthola Isitifiketi: Ukuhlolwa Okuqinile Nenqubo Ende
Ukuthola isitifiketi se-KTW akuyona into elula. Kuyinqubo ethatha isikhathi, edinga amandla amaningi, futhi ebiza kakhulu, okubonisa ukucophelela okudumile kweJalimane.

1. Ukubuyekezwa Kwangaphambi Kokuqala Nokuhlaziywa Kwezinto Ezibalulekile:
   Abakhiqizi kumele baqale bathumele uhlu olunemininingwane lwazo zonke izingxenye zomkhiqizo enhlanganweni yesitifiketi (isb., ilabhorethri evunyelwe yi-UBA noma i-DVGW), kufaka phakathi ama-polymer ayisisekelo (isb., i-EPDM, i-NBR, i-FKM) kanye namagama amakhemikhali aqondile, izinombolo ze-CAS, kanye nezilinganiso zazo zonke izithako. Noma yikuphi ukushiywa noma ukungalungi kuzoholela ekwehlulekeni kwesitifiketi ngokushesha.
2. Izinqubo Zokuhlola Okuyinhloko:
   Amasampula ezinto ahlolwa amasonto amaningi ezindaweni zokucwaninga ezilingisa izimo ezahlukene zamanzi okuphuza ezimbi kakhulu. Ukuhlolwa okubalulekile kufaka phakathi:
   • Ukuhlolwa Kwezinzwa: Ukuhlola izinguquko ephunga lamanzi kanye nokunambitheka kwawo ngemva kokucwiliswa kwezinto ezibonakalayo.
   • Ukuhlolwa Okubonakalayo: Ukuhlola ukuthi amanzi ayaguquguquka yini noma awanawo umbala.
   • Ukuhlolwa Kwezinto Eziphilayo (DVGW W270): Ukuhlola ikhono lento yokuvimbela ukukhula kwamagciwane. Lesi isici esivelele sokuqinisekiswa kwe-KTW, okuyenza ihluke kwezinye (isb., i-ACS/WRAS) ngezindinganiso zayo eziphakeme kakhulu.
   • Ukuhlaziywa Kokufuduka Kwamakhemikhali: Ukuhlolwa okubaluleke kakhulu. Kusetshenziswa amathuluzi athuthukile njenge-GC-MS (i-Gas Chromatography-Mass Spectrometry), amanzi ahlaziywa nganoma yiziphi izinto eziyingozi ezikhipha amanzi, kanti amazinga awo alinganiswa ngokunembile. Inani eliphelele labo bonke abafudukayo kumele lihlale lingaphansi kwemingcele echazwe ngokuqinile.
3. Ukuhlolwa Okuphelele Nokwesikhathi Eside:
   Ukuhlolwa kwenziwa ngaphansi kwezimo eziningi—amazinga okushisa amanzi ahlukahlukene (abandayo nashisayo), ubude bokucwiliswa, amazinga e-pH, njll.—ukuze kulingisa ubunzima bomhlaba wangempela. Inqubo yonke yokuhlola nokugunyaza ingathatha izinyanga eziyisithupha noma ngaphezulu.

Ngakho-ke, uma ukhetha uphawu olunesitifiketi se-KTW, awukhethi nje umkhiqizo, kodwa uhlelo oluphelele oluqinisekisiwe lwesayensi yezinto ezibonakalayo kanye nokuqinisekiswa kwekhwalithi.

Isahluko 5: Ngale KweJalimane: Ithonya Lomhlaba Wonke le-KTW kanye Nenani Lemakethe
Nakuba i-KTW yaqala eJalimane, ithonya layo kanye nokuqashelwa kwayo kuye kwanda emhlabeni wonke.

• Isango Lokuya Emakethe YaseYurophu: Kuyo yonke i-EU, yize indinganiso ehlanganisiwe yaseYurophu (i-EU 10/2011) izogcina isithathe indawo yayo, i-KTW isalokhu iyindinganiso ethandwayo noma ebalulekile yokubhekisela emazweni amaningi kanye namaphrojekthi ngenxa yomlando wayo wesikhathi eside kanye nezidingo eziqinile. Ukuba nesitifiketi se-KTW kufana nokufinyelela emakethe yamanzi ephezulu yaseYurophu.
• Ulimi Olujwayelekile Ezimakethe Zomhlaba Wonke Ezisezingeni Eliphezulu: ENyakatho Melika, eMpumalanga Ephakathi, e-Asia, nakwezinye izifunda, izinhlobo eziningi zokuhlanza amanzi ezisezingeni eliphezulu, izinkampani zobunjiniyela bamanzi, kanye nabakhi bephrojekthi bamazwe ngamazwe babheka isitifiketi se-KTW njengesibonakaliso esibalulekile sekhono lobuchwepheshe lomhlinzeki kanye nokuphepha komkhiqizo. Kuthuthukisa kakhulu inani lomkhiqizo kanye nedumela lomkhiqizo.
• Isiqinisekiso Sokuthobela Imithetho Esiqinile: Kubakhiqizi abangaphansi komfula (isib., abahlanzi bamanzi, ama-valve, izinhlelo zamapayipi), ukusebenzisa izivalo eziqinisekiswe yi-KTW kungenza inqubo yokuthola izitifiketi zokuphepha kwamanzi zasendaweni ibe lula kakhulu (isib. i-NSF/ANSI 61 e-US, i-WRAS e-UK), kunciphisa izingozi zokuthobela imithetho kanye nezindleko zesikhathi.

Ku-Ningbo Yokey Co., Ltd., ukutshala izinsiza ekutholeni izitifiketi eziningi zamazwe ngamazwe, kufaka phakathi i-KTW, akuphathelene nokuphishekela iphepha. Kuvela emsebenzini wethu oyinhloko wenkampani: ukuba ngumlingani wesixazululo sokuvala othembekile kakhulu kumakhasimende omhlaba wonke. Siyaqaphela ukuthi imikhiqizo yethu, nakuba imincane, inemithwalo yemfanelo ebalulekile yokuphepha.

Isahluko 6: Ungaqinisekisa Kanjani Futhi Ukhethe? Isiqondiso Sabalingani
Njengomthengi noma unjiniyela, kufanele uqinisekise futhi ukhethe kanjani imikhiqizo eqinisekisiwe ye-KTW efanelekile?

1. Cela Izitifiketi Zokuqala: Abahlinzeki abahloniphekile kufanele banikeze amakhophi noma izinguqulo ze-elekthronikhi zezitifiketi ze-KTW ezikhishwe yizinhlangano eziqashelwa ngokusemthethweni, ezigcwele izinombolo zokuhlonza ezihlukile.
2. Qinisekisa Ububanzi Besitifiketi: Hlola imininingwane yesitifiketi ukuqinisekisa ukuthi uhlobo lwezinto eziqinisekisiwe, umbala, kanye nobubanzi bokushisa kokusetshenziswa (amanzi abandayo/ashisayo) kuyafana nomkhiqizo owuthengayo. Qaphela ukuthi isitifiketi ngasinye sivame ukusebenza ekwakhiweni okukodwa okuthile.
3. Themba kodwa Qinisekisa: Cabanga ngokuthumela inombolo yesitifiketi kugunya elikhiphayo ukuze iqinisekiswe ukuqinisekisa ubuqiniso bayo, ukusebenza kwayo, nokuthi ihlala ingakapheli isikhathi sokuphelelwa yisikhathi.

Yonke imikhiqizo efanele evela ku-Ningbo Yokey Co., Ltd. ayigcini nje ngokuthobela isitifiketi se-KTW kodwa futhi isekelwa uhlelo lokulandelela kusukela ekuqaleni kuze kube sekupheleni—kusukela ekuthathweni kwezinto zokusetshenziswa kuya ekuthunyelweni komkhiqizo oqediwe—okuqinisekisa ikhwalithi nokuphepha okuqhubekayo kweqoqo ngalinye.

Isiphetho: Ukutshala imali ku-KTW Kuwukutshala Imali Ekuphepheni Nasesikhathini Esizayo
Amanzi angumthombo wokuphila, futhi ukuqinisekisa ukuphepha kwawo kuwumjaho wokudlulisa kusuka emthonjeni kuya empompini. Izimpawu zerabha zisebenza njengomlenze obalulekile walo mjaho, futhi ukubaluleka kwazo akunakunganakwa. Ukukhetha izimpawu eziqinisekiswe yi-KTW kuwukutshalwa kwezimali okunesu ekuphepheni komkhiqizo, impilo yomsebenzisi, idumela lomkhiqizo, kanye nokuncintisana emakethe.

I-Ningbo Yokey Co., Ltd. isalokhu izibophezele ekuhlonipheni isayensi, ukunamathela ezindinganisweni, kanye nokuzinikela ekuphepheni.
