Tom qab lub khob thermos "tuag" tau nthuav tawm, cov nqi sib txawv heev. Cov pheej yig xwb raug nqi kaum tawm yuan, hos cov kim kim kim mus txog phav phav yuan. Puas pheej yig thermos khob yuav tsum tsis zoo? Cov khob thermos kim puas raug them se IQ?
Hauv xyoo 2018, CCTV nthuav tawm 19 hom "tuag" lub khob thermos ntawm lub khw. Tom qab nchuav hydrochloric acid rau hauv lub khob thermos thiab tso nws rau 24 teev, ntau cov manganese, nickel thiab chromium hlau tuaj yeem kuaj pom hauv hydrochloric acid.
Peb cov no yog cov hlau hnyav. Lawv cov ntsiab lus ntau dhau tuaj yeem ua rau muaj kev tiv thaiv qis, ua xua ntawm daim tawv nqaij, thiab ua rau mob qog noj ntshav. Lawv muaj kev phom sij tshwj xeeb rau cov neeg laus thiab menyuam yaus, thiab tuaj yeem ua rau kev loj hlob dysplasia thiab neurasthenia.
Qhov laj thawj yog vim li cas lub khob thermos muaj cov hlau hnyav no yog vim nws lub tank sab hauv feem ntau yog ua los ntawm peb cov khoom siv hlau tsis zoo, xws li 201, 304 thiab 316.
201 stainless hlau yog cov hlau tsis muaj hlau tsis muaj chromium thiab cov ntsiab lus npib tsib xee. Txawm li cas los xij, nws yog qhov yooj yim rau xeb hauv qhov chaw ntub dej thiab nws yooj yim rau corrosion thaum raug cov tshuaj acidic, yog li precipitating hnyav hlau. Nws tsis tuaj yeem tiv nrog zaub mov thiab dej qab zib tau ntev.
304 stainless hlau feem ntau suav hais tias yog cov khoom noj khoom haus qib thiab tuaj yeem siv los ua cov liner ntawm lub khob thermos; 316 stainless hlau yog kev kho mob-qib stainless hlau, uas muaj kev ruaj ntseg dua thiab tshwj xeeb tshaj yog corrosion-resistant.
Yuav kom txuag tau cov nqi, qee cov tub lag luam uas tsis ntseeg siab feem ntau xaiv qhov pheej yig tshaj 201 stainless hlau ua cov liner sab hauv ntawm lub khob thermos. Txawm hais tias cov thermos khob no tsis yooj yim rau tso cov hlau hnyav thaum sau cov dej kub, lawv tau yooj yim puas thaum lawv nkag rau hauv cov dej qab zib thiab kua txiv hmab txiv ntoo. Corrosion, ua rau cov hlau hnyav heev.
Lub teb chaws cov qauv ntseeg tau hais tias lub khob thermos uas tsim nyog tuaj yeem muab rhaub hauv 4% acetic acid tov rau 30 feeb thiab soaked rau 24 teev, thiab cov hlau hauv chromium tsiv teb tsaws tsis tshaj 0.4 mg / square decimeter. Nws tuaj yeem pom tias txawm tias lub khob thermos tsis zoo yuav tsum ua kom tau raws li cov qauv ntawm kev muaj peev xwm tuav cov dej qab zib carbonated, tsis yog cia cov neeg siv khoom khaws cov dej kub xwb.
Txawm li cas los xij, cov khoom tsis tsim nyog thermos khob hauv khw muag khoom yog ua los ntawm cov khoom lag luam qis qis, cov hlau tsis muaj xeb lossis siv cov hlau tsis zoo, uas yuav ua rau tib neeg noj qab haus huv.
Qhov tseem ceeb yog tias tus nqi ntawm cov thermos khob no tsis yog txhua yam khoom pheej yig. Ib txhia yog ntau tshaj kaum lossis nees nkaum yuan txhua, thiab qee qhov siab li ib lossis ob puas yuan. Feem ntau hais lus, 100 yuan yog txaus rau cov lag luam siv cov ntaub ntawv nyab xeeb los tsim cov thermos khob. Txawm hais tias tsis muaj qhov tshwj xeeb yuav tsum tau ua rau cov nyhuv rwb thaiv tsev, kaum tawm yuan tuaj yeem ua tiav.
Txawm li cas los xij, ntau lub khob thermos ib txwm hais txog lawv qhov kev ua haujlwm thermal rwb thaiv tsev, muab cov neeg siv khoom pom tias lawv cov khoom muaj kev nyab xeeb kiag li. Thaum xaiv lub khob thermos ntawm kev ua lag luam, peb yuav tsum ua tib zoo mloog thiab sim xaiv lub npe me ntsis kom paub zoo dua. Txawm li cas los xij, muaj cov thermos khob nrog SUS304 thiab SUS316 ntawm lub tank sab hauv.
Nyob rau tib lub sijhawm, koj kuj yuav tsum tau soj ntsuam seb puas muaj cov cim ntawm xeb hauv lub khob thermos, seb qhov chaw yog du thiab translucent, seb puas muaj ntxhiab tsw ntxhiab, thiab lwm yam. Feem ntau hais lus, lub tank sab hauv tsis muaj xeb, du nto. thiab tsis muaj ntxhiab tsw tuaj yeem lav tau tias cov khoom yuav tsis xeb thiab nws yog cov tshiab tsim stainless hlau.
Tus nqi ntawm thermos khob tam sim no nyob rau hauv kev ua lag luam sib txawv. Cov khob thermos pheej yig dua me ntsis siv cov cuab yeej tshem tawm tus Tsov tus tw thiab muaj qhov zais tail chamber rau hauv qab rau kev txuag hluav taws xob, tab sis lawv siv ntau qhov chaw thiab txo cov dej cia.
Cov khob thermos kim dua feem ntau tshem tawm cov qauv no. Lawv feem ntau siv sib dua thiab muaj zog austenitic stainless hlau liner (tseem yog SUS304 stainless hlau). Hom stainless hlau no tswj cov ntsiab lus ntawm cov hlau chromium ntawm 16% -26%, uas tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm chromium trioxide rau saum npoo thiab muaj zog corrosion kuj.
Txawm li cas los xij, cov khob thermos ntawm lub khw muag khoom muag ntau dua 3,000 txog 4,000 yuan txhua zaus muaj lub tank sab hauv ua los ntawm titanium alloy. Cov nyhuv rwb thaiv tsev ntawm cov khoom siv no zoo ib yam li cov hlau tsis muaj steel. Qhov tseem ceeb yog tias nws muaj kev nyab xeeb heev, vim tias titanium tsis ua rau hnyav hlau lom. Txawm li cas los xij, tus nqi no yeej tsis tsim nyog rau cov neeg feem coob.
Feem ntau hais lus, feem ntau lub khob thermos tsis suav tias yog IQ se. Qhov no zoo ib yam li kev yuav lub lauj kaub hauv tsev. Lub lauj kaub hlau uas raug nqi ntau dua li ib daim tsis tas yuav phem, tab sis qhov tshwm sim ntawm kev ntsib cov khoom tsis zoo yuav nce ntxiv. Ib yam khoom uas muaj nqi heev tsis tau raws li qhov xav tau ntawm cov neeg feem coob. Ua ke, yuav cov khoom luv nqi ntawm 100-200 yuan yog qhov kev xaiv ntawm ntau tus neeg.
