VIGA Faucet Mugadziri 
1. Preface
Parizvino, Iyo yemukati maindasitiri anogadzira faucets ane zvinhu zvikuru zvinosanganisira ndarira, simbi isina ngura, Purasitiki, etc. Ruzhinji rwekutengesa mumisika yakagadzirwa yeEurope uye United States ndeye mhangura matipi, China, Sekureva kwapasi rose kwehukuru hwematipi, Mazhinji ematare ekutumira kunze kwemapapheni emapuranga. Zvinyorwa zvikuru zvezvemhangura fa fura uye zpper uye zinc, inowanzozivikanwa sekaruva. Chikamu chidiki chebvu chinowedzerwa kune iyo ndarira panguva yemachinda maitiro ekuvandudza kutema kwekuita kwendarira. Kana pasina kutungamira kunowedzerwa zvachose, Iyo faucet haizove yakaoma kutema, Murombo Anokanganwira Kuita uye Zvimwe Zvinetso, Kunyangwe kana chigadzirwa chakapera, Izvo zvakare zvichaitawo kupaza nekuda kweshungu dzinoshamwaridzana kupokana
Tungamira isimbi inorema iyo inokuvadza hutano hwevanhu, asi mafuro makuru munyika dzakabudirira muEurope uye America yakagadzirwa nendarira, uye ndarira haina kutsiviwa nezvimwe zvinhu. Izvi zvinodaro nekuti kupfupika kwemutobvu kunogumira nezvigadzirwa zvechigadzirwa kune imwe kukosha uye inoonekwa yakachengeteka. Semuyenzaniso, Iyo North American Faucet inexicity bvunzo, NSF / Ansi61-2012, inoda kuti itungamire kutungamira kusati kwadarika 5 μG inofungidzirwa kuti yakachengeteka.
Saka, Tichifunga nezvehutano hwehutano hwakakonzerwa nehurema hwesimbi simbi, Nheyo dzeNyika Itsvanyiriri (NSF) kuitiswa mukudzika-kumashure kutsvagurudza uye kuongororwa kwehuremu hwesimbi simbi muzvigadzirwa mukuwirirana nekumwa mvura, Yakagadzirira iyo bvunzo standard NSF / ANSI61, yakagadzirwa yakadzama nzira yekuongororwa uye kudzikisira zvinodiwa zvinodiwa, uye yave iri mubatsiri weChexity testity test chiyero chekunwa mvura yekunwa mashandiro ekutarisa muNorth America. Chiyero chinogamuchirwa zvakanyanya mune dzimwe nyika nematunhu, kusanganisira china, yekuongororwa kwekuremerwa kwesimbi simbi kubva pamatanga nekutaura zvakananga kana zvisina kunanga.
2.NSF / Ansi61-2012 Standard
2.1 Nhanganyaya kune chiyero “Kunwa mvura yemvura – Health Mhedzisiro” [1] yakagadzirwa neiyo National Sanitation Foundation (NSF), Sezvo iyo yekutanga yekutanga yakapihwa mukati 1988, Mushure mevhisi yakati wandei yeiyo update, iyo yazvino shanduro ndiyo 2012 vhezheni yeicho chazvino.nsf / ansi 61-2012 Standard Covers zvigadzirwa zvinosanganisira pombi system (mapaipi uye zvakakodzera), Zvigadzirwa Zvekudzivirira, Kuongorora Zvinhu, mavharuvhu, Kupera Zvigadzirwa (samapipi, etc.).
2.2 NSF / ANSI& 61 inorema simbi yekufungidzira bvunzo maitiro ematumba emvura
Iyo NSF / ANSI 61-2012 Test chikamu cheFacets chikamu 9, izvo zvine simba kwazvo uye zvine simba kwazvo kuNorth America sechiyero chekuongorora simbi inorema uye organics kusimuka kubva kuFucet zvigadzirwa kubva kuhurongwa hwekuedza maitiro. Muchikamu 9, iyo faucet, sechigadzirwa chekupedzisira, ndeye default yakafumurwa kune yekupedzisira 1 litre yemvura, i.e. IZVI izvi 1 litita yemvura inokanganiswa neiyo chaiyo yekunyepedzera masimbi uye zvisikwa.
Iyo inorema simbi yekuedza inoitwa nekutora matatu akazara seti yematanho uye kutanga kunyepedzera neChishanu masikati. Kutanga kugeza iyo faucet ine tap mvura uye wozadza iyo ine mvura inodonha. Kubva pazuva 1 kusvika pazuva 18, Kunze kweMugovera neSvondo, chinja mhinduro yekunyanyisa 2 maawa kubva 9:00 ku 17:00, 5 nguva pazuva. Zvinobuda zvakaunganidzwa 9:00 pamazuva 3, 4, 5, 10, 11, 12, 17, 18 uye 19 Zvekutungamira uye 9:00 pazuva 19 Kune vakasara 13 Simbi Inorema.
2.3 NSF / ANSI 61 Kuverenga kweiyo q kukosha kwematipi
Sepamusoro pekutungamira zvirimo chiratidzo chakasimba maitiro, huwandu hwenzvimbo dzinosiyana kubva panguva yekudzika nguva yekunyora. Kuti udzikise huwandu hwepakati huwandu hwemutungamiri hwakarongedzwa panguva yakapihwa, Nsf yakaisa nhamba yehuwandu, yakaverengerwa yakagadziriswa makomendi uchishandisa logarithmic zvinoreva uye yakajairika kutsauka, uye pakupedzisira yakaverengera kukosha kwehuwandu Q kuti utungamire kuwanikwa.
(1) Yakagadziriswa kusangana inoverengwa neiyo inotevera formula: NF = N1 × N2 × CMV
(2) Mu equation, N1 =(Saf / Sal)Vl / vf(Static))N2vf(Static)/Vf(kuyerera)=; Sal ndiyo nzvimbo yechigadzirwa kunyudzwa panguva yekuyedza; Vl ndiyo huwandu hwemvura hwakazadzwa panguva yekuedzwa; Vf(Static) inotsanangurwa pano se 1l. CMV ndiyo inotonhora mvura mamiriro echinhu (= mvura inotonhora yakazara vhoriyamu / yakazara mvura yakazadza vhoriyamu).
(3) Verenga iyo yakasikwa logarithm yeiyo yakagadziriswa yekushambadzira uchishandisa fomula yij = lnxij.
(4) Kuverenga iyo logarithmic zvinoreva kune yega ye 3 samples maererano neye inotevera formula: Ita =(Yi3 + yi4 + yi5 + yi10 + yi11 + yi12 + yi17 + y18 + yi19)/9
(5) Verenga kutsauka kwakajairika kweiyo logarithmic zvinoreva zvinoenderana neyekutevera formula: (6) Kuverenga iyo q kukosha zvichienderana neye inotevera formula: Iko k ndiko kusingaperi kukosha kweiyo nhamba yemitambo iyo zvinoenderana nehukuru hweyekuedzwa kwemuenzaniso, K = 2.6028 Kana zviripo 3 bvunzo samples.
2.6 NSF / ANSI61 inorema simbi bvunzo mhinduro pane faucet kukwira, Sekutanga kwechitatu-bato rekuyedza sangano mu Mainland china iyo inogona kuitisa NSF / ANSI61 kuyedza, Isu tinopfupisa ruzivo rweNSF / ANSI61 kuyedza pane faucets pane zvakapfuura 8 makore uye kusvika kune inotevera mhedziso: (1) Tungamira zvisizvo, Asi maitiro ese anowedzera zvishoma nezvishoma kuderera. (2) Kazhinji, Kurema kwesimbi kutadza kwekutadza kunonyanya kutaurwa mune inotevera simbi inorema: tungamira, Copper, Arsenic, zinc, Cadmium, etc. Nhamba dzekupedzisira 100 Models of Faucets NSF / Ansi61 bvunzo mhinduro, izvo 92, kana 92%, akapfuura bvunzo, Kukundikana 8, chiyero chekutadza che 8%. Ye 8 Models Yakundikana, Iko kukosha kweQ yekutungamira kwekutungamira kwakundikana kuzvidavirira 3, Copper, Arsenic, zinc, Cadmium, chromium yezviri kutadza account 1 imwe neimwe.
3.NSF / ANSI61 pane iyo kukanganiswa kweiyo faucet indasitiri nekuda kweiyo North American Faucet Faucet Testing Standard Asmea112.18.1 Inotendera iyo yakakwira kutungamira yemukati yemhangura mumatare emvura ari 8%, Asi mabhizinesi mazhinji ekugadzira ane hanya nezvekushandiswa kwakananga kwekutungamira kwemukati memusoro wepfuma yedutu yakaomesesa kupfuudza iyo NSF / ANSI6 TEST, Saka mamwe mabhizinesi anozosarudza kushandisa akaderera kutungamira mhangura kana kutotungamira-yemahara emhangura fapper, Asi maitiro achinja, Maitiro ehunyanzvi uye mutengo wakakwira.
Mamwe mabhizinesi achashandisa iyo “kutungamira kwekushambidza” nzira yekubvisa kutungamira kubva kumvura yemvura, Iyo nheyo ndeye kushandisa iyo mhangura-kutungamira yekunyungudika mhinduro musiyano. Tembiricha yeFucet kukanda kazhinji kazhinji kupfuura 1,000 Dhigirii celsius, uye iyo yekunyungudika yenzvimbo ndeye 327.5 Dhigirii celsius, zvekuti kutungamira mukuumbwa kwenzvimbo yemukati neyekunze kwekutungamira kwekutungamira.
Iyo inotungamira yemukati pamusoro pechiso yakakwira kupfuura mukati. Kushambidza tungamira usati wabuda mufekitori kushandisa iyo sarudzo yemakemikari maitiro maitiro, Nekushambadzira kwakanyanya kweiyo yakasimba alkali solution yekubata sampuli, geza kumeso kwezvinhu zvakanaka, uyezve zvakaringana acid kurwa, Ipapo kutungamira mumhangura faucet inokurumidza kuora mwoyo. MuNSF / ANSI61 bvunzo, Iko kukosha kweQuecet yaive 8.5μG usati washamisa uye 4.1μg mushure mekugeza kutungamira, Nekuderera kwakakosha muQ kukosha.
4. Pfupiso yakasanganiswa nechiitiko chekutanga chetungamiri mufuma, Iko kutarisisa kwekukakavara kwayo, inonyanya kusiyana mukuyedza nzira. Mamwe masangano anotora nzira yakagadziriswa yemukati, vamwe vanotora nzira yekudyidzana, uye vamwe vanotora nzira yakakurudzirwa yenyika, Nenzira dzakasiyana siyana uye zvakasikwa zvakaringana mhedzisiro. Izvi zvinotungamira pakushayikwa kwekufanana uye asymmetry mune media uye neruzhinji ruzivo. Saka, Sezvo iyo nyowani yenyika yenyika yave kuda kuitwa, Isu tinokurudzira kuti NSF / ANSI61 kuburitswa seyunivhesiti yekufungidzira nzira yeFaucets kuti aedze kuongororwa kwakawanda masimbi mazhinji senge anotungamira kubva pamaonero ehurongwa. Nzira dzekuyedza uye zvinodiwa zvinogona kuve zvakarongedzwa kumamiriro azvino eindasitiri
