Cov ntaub ntawv tsom xam ntawm kais dej raug: tooj liab, stainless hlau, thiab zinc alloy

Tooj liab (tooj dag): Cov ntaub ntawv tshaj tawm rau kev siab -} kais dej

Raug pes tsawg leeg:

Tooj dag yog ib qho kev ua los ntawm:

Tooj Liab (Cu): 57-60%

Zinc (Zn): 35-40%

Ib txoj kab tseg: Lead (PB), Tin (Sn), Hlau (FE), ALUMIN, ETC.

Siab -}}}}}}}}} ionucet raug feem ntau tau raws li cov qauv hauv ntiaj teb xws li:

CW617N (EN 12165)

HPB59-1 (CHAN CHANCORS)

Cov yam ntxwv ua:

Luam ntaub: zoo heev, tshwj xeeb tshaj yog nrog cov kab tooj dag.

Casting thiab Forging: Haum rau ob qho tib si, nrog siab seem ruaj khov.

Plating sib xyaw: zoo tagnrho rau chrome, npib tsib xee, thiab kub tiav.

Corrosion Kuj: muaj zog nyob rau hauv ib puag ncig dej.

Kev tsim khoom nyuaj:

Nruab nrab - yuav tsum tau tshaj tawm cov khoom siv ua pov lossis forging cov txheej txheem thiab feem ntau cnc machining. Cov ntsiab lus coj yuav tsum tau tswj kom ua raws li cov cai (piv txwv li, NSF / ansi 61 hauv Asmeskas).

Kev Xav Tau Lag Luam:

Nyiam rau high - kawg thiab ua lag luam- baec fireucets.

Muaj ntau yam nyob rau sab qaum teb America, Europe, thiab hwm tsev so thiab cov phiaj xwm.

Rising thov kom muaj tsawg - Le} {{1} {{1} {dawb tooj dag yog hloov mus rau ecobrass lossis C6801 hom.

Tus Hlau Stainless: Lub Ntev thiab EMO - Txoj Kev Zoo Lwm Tus

Raug pes tsawg leeg:

Kaiscet - qib steels stainless hlau muaj xws li:

304 Stainless Hlau:

Hlau (FE): Tshuav

Chromium (CR): 18-20%

Nickel (NI): 8-10.5%

316 Cov Hlau Stainless (Tubrog - qib):

Ntxiv 2-3% molybdenum (mo) rau txhim kho corrosion tsis kam.

Cov yam ntxwv ua:

Luam Ntawv: Harder rau lub tshuab tsis yog tooj dag lossis zinc alloy.

Forging / Casting: nyuaj; Feem ntau cnc - phoo ntawv los ntawm cov khoom tuav lossis peev cam khwb.

Plating: feem ntau tsis tas yuav; Nto polishing yog ib yam.

Corrosion Kuj: Zoo heev, tshwj xeeb tshaj yog 316 nyob rau hauv ntug dej hiav txwv.

Kev tsim khoom nyuaj:

Siab - yuav tsum muaj siab - ceev cnc khoom, kev tswjhwm zoo, thiab sijhawm siv sijhawm ntev dua. Tuam kev hnav yog siab dua, nce nqi tsim khoom.

Kev Xav Tau Lag Luam:

Ua kom nrov dua rau eco - Tus phooj ywg, Lead- kais dej dawb.

Nrov nyob hauv Tebchaws Europe, Nyiv, thiab Hwm cov kev lag luam uas cov neeg tau txais kev nyiam huv thiab kav ntev.

Txwv los ntawm cov nqi ntau lawm thiab lub sijhawm ua haujlwm.

Zinc Alloy: cov teeb meem pheej yig rau cov kais dej

Raug muaj pes tsawg:

Zinc Alloy (feem ntau zamak 3 lossis zamak 5) suav nrog:

Zinc (Zn): 95%

Aluminium (Al): 3-4%

Tooj Liab (Cu): 0.5-1%

Ib txoj kab tseg: magnesium (mg), npib tsib xee (ni)

Cov yam ntxwv ua:

Tuag Casting:Tsis tshua muaj neeg yooj yim thiab raug nqi -}}} Zoo rau cov duab nyuaj.

Machinability:Zoo, Tsawg Tshaj Plaws Post - Taug kev xav tau.

Plating Compatibility:Yuav tsum tau npaj ua si kom zoo, tab sis ua tiav yuav txaus nyiam.

Corrosion Kuj:Tsis muaj zog dua tooj dag lossis stainless hlau, yuav tsum muaj qhov zoo txheej.

Kev tsim khoom nyuaj:

Qes - zoo tagnrho rau high - nplej ntau lawm nrog tus nqi qis. Zoo heev tas qhov tseeb los ntawm kev tuag casting. Tsis haum rau ntu hauv kev sib chwv nrog cov dej nyob hauv ntau lub teb chaws vim tias muaj kev txhawj xeeb corrosion thiab leaching.

Kev Xav Tau Lag Luam:

Dominates qhov qis - rau nruab nrab-} kais dej ua lag luam, tshwj xeeb tshaj yog nyob rau hauv:

Miskas qab teb

Southeast Asia

Qhov chaw ntawm Africa
