Stainless hlau yog cov khoom siv hlau siv dav hauv kev lag luam xws li roj av, tshuaj, thiab chiv. Ferritic stainless hlau hais txog stainless hlau nrog cov ntsiab lus chromium ntawm 11% mus rau 30%, lub cev-centered cubic crystal qauv, thiab cov qauv ferrite feem ntau thaum siv. Nws yog dav siv nyob rau hauv cov khoom siv hauv tsev, kho kom zoo nkauj architectural, khoom siv hauv chav ua noj, tableware, thiab lwm yam. Ntau yam kev sib raug zoo nrog tib neeg lub neej.
1. Qhov xwm txheej tam sim no
430 stainless hlau, raws li tus neeg sawv cev ntawm ferritic stainless hlau, yog ib qho kev pab txuag stainless hlau. Vim nws cov ntsiab lus chromium siab, ferritic stainless hlau muaj qhov zoo corrosion kuj thiab cov khoom tiv thaiv oxidation, tab sis cov khoom siv tsis zoo thiab cov txheej txheem. Yog li ntawd, nws yog feem ntau siv nyob rau hauv acid-resistant lug nrog me ntsis kev nyuaj siab thiab raws li ib tug anti-oxidation steel hom. Cov yam ntxwv ntawm 430 stainless hlau tsuas yog ua tau raws li cov khoom xav tau ntawm chav ua noj ib puag ncig thiab stainless hlau tableware, yog li nws yog dav siv hauv stainless hlau tableware.
2. Lus nug
430 stainless hlau tableware yog cov khoom siv niaj hnub uas muaj kev sib cuag nrog zaub mov. Yog tias nws tsis ua haujlwm zoo thaum siv, cov khoom hlau uas muaj nyob rau hauv stainless hlau yuav nkag mus rau hauv cov zaub mov los ntawm kev ua noj nruab nrab thiab yuav noj los ntawm tib neeg lub cev. Lawv yuav maj mam sib sau nyob rau hauv tib neeg lub cev. Thaum lawv ncav cuag ib theem, lub sij hawm, nws yuav ua rau tib neeg noj qab haus huv. Yog li ntawd, nws qhov ntsuas kev noj qab haus huv yog qhov ntsuas tseem ceeb ntsig txog tib neeg kev nyiam huv, kev nyab xeeb thiab kev noj qab haus huv. Lub teb chaws thiab txawm lub ntiaj teb no muaj cov qauv kev noj qab haus huv nruj rau cov hlau hnyav xws li chromium, npib tsib xee, arsenic thiab txhuas. Chromium yog tshuaj lom heev rau tib neeg lub cev thiab ua rau lub cev puas tsuaj. Chromium muaj zog stimulating nyhuv ntawm daim tawv nqaij daim nyias nyias, ua rau eczema, dermatitis, tracheitis thiab rhinitis, ua rau muaj kev tsis haum tshuaj thiab tej zaum yuav ua rau mob cancer; nws cuam tshuam rau cov kabmob hauv lub cev, tshwj xeeb tshaj yog rau lub raum thiab daim siab. Thaum ob lub cev muaj teeb meem, Kev tswj lub cev cov metabolism hauv lub cev yuav ua rau muaj teeb meem, daim siab ascites, cirrhosis, thiab txawm tuag. Suav thiab German cov qauv xav kom cov nag lossis daus los ntawm chromium tsawg dua lossis sib npaug li 0.4mg.dm-2, tab sis qhov no tsis yog qhov tseeb.
3. Ua rau thiab kho
In the production process of 430 ferritic stainless steel tableware, improper heat treatment process leads to the segregation of impurity carbides and martensite residue, which then causes galvanic corrosion reaction in the corrosive medium, ultimately leading to excessive chromium ion precipitation (>0.4mg .dm-2), teeb meem rau kev noj qab haus huv.
Ferritic stainless hlau cov khoom tuaj yeem raug muab tshem tawm tom qab ua tiav kom txo qis martensite. Nyob rau tib lub sij hawm, thaum lub sij hawm annealing txheej txheem, koj yuav tsum tsis txhob nyob rau hauv lub intergranular corrosion-rhiab kub cheeb tsam (850 ~ 950 degree) ntev. Koj tuaj yeem xaiv qhov nruab nrab, qhov kub thiab txias ceev kom tsis txhob muaj qhov tshwm sim ntawm kev xeb hauv zos.
