Stainless steel tableware, had better choose which kind of?

I see there is an article to say vacuum cup cannot use outfit fruit juice on evening paper, otherwise the heavy metal in the cup is met migratory come out.
I am a bit serious after looking, my home is not little tableware is stainless steel, often feel vinegar at ordinary times. Stainless steel container installs fruit juice cannot, is encountering vinegar more insecure? ”
Lady of citizen goldenrain tree saw newspaper publish " fruit juice of vacuum cup outfit has bit of risk oh " after one article, dialed the telephone of column, say her home loves jealous, dare use stainless steel dinner service not quite nowadays.
Is this kind of worry of goldenrain tree lady reasonable?
Dispel doubt: Some fruit juice are caustic stronger than vinegar
Be aimed at the doubt of goldenrain tree lady, the reporter contacted Master of staff room of science of material of university of Qingdao science and technology and stuff of engineering courtyard metal to give birth to adviser Xu Lei to answer back and forth.
“ deposits fruit juice to should not be really the container that uses stainless steel raw material, still be good with terrarium contrast. Explanation of ” Xu Lei says,
“ because contrast of some fruit juice is acerbity,this is, PH value can arrive 1.2, growing hour to feel stainless steel meet some corrode action.
” but, PH value of vinegar follows so fruit juice comparing, relatively a few lower, and go to often mix with stainless steel chopstick, ladle, the dish that clip contains a lot ofvinegar, feel so a few minutes, needing only is the stainless steel with good quality, it is interrogative of it doesn't matter.
Analysis: 304 stainless steel are opposite the safest
What kind of stainless steel is just the stainless steel with the good quality that Xu Lei says?
“ stainless steel also distinguishs a lot of breed, if apply austenite stainless steel, also be namely what say 304 stainless steel as one used to do, be provision level, fight etch action contrast aspiration. ”
Dan Xulei also reminds, tableware of some stainless steel is not to use this kind namely certainly, what some use is the stainless steel of 200 series, fight corrode action a few poorer. Corrosion product is the inside metal of stainless steel namely, for instance chromium is mixed manganese, if the quantity is little, also need not ham and serious, the microelement of “ human body also is demand of a few heavy metal. ”
Of course, we hope absorbed undesirable material has been jumped over lesser, so when choosing stainless steel dinner service, of 304 raw material is most of aspiration. This kind of tableware should be purchased to big market, supermarket normally, product label can look to defend oneself when buying.
Outspread: Good stainless steel not dread is subtle wear away
The person that uses stainless steel dinner service should have experience —— to always grow what this kind of tableware uses, wash rinse to brush outside and unavoidable meeting to have wear away. Once appear,wear away, did retouch feel acidity material to separate a harmful heavy metal simply?
Stainless steel of “ provision level is exterior, in-house it is to be able to be fought corrode. ” Xu Lei informs a reporter, about 304 stainless steel character, subtle wearing away is not doubt, do not affect apply.
Need cleanness only clean, do not replace inside demand short hour, unless appearance has a lot of nick, accumulate dirty stuff so simply, and be washed not easily drop, just be worth to change at this moment.
This chopstick with wood, bamboo is different, optimal half an year changes these chopsticks.
