Nrog rau kev ua raws li kev hloov kho thiab qhib txoj cai, lub teb chaws kev lag luam tau ua tiav kev loj hlob sai, thiab kev tsim kho loj hauv nroog, vaj tse pej xeem, thiab cov chaw ncig ua si tau muab cov kev xav tau tshiab rau cov dej kub thiab dej hauv tsev. Tib neeg tau mob siab rau cov teeb meem dej tsis zoo thiab lawv cov kev xav tau txhim kho tas li. Qhov tshwm sim ntawm cov kav dej stainless hlau tau ua kom yooj yim dua rau tib neeg lub neej.
Feem ntau siv galvanized steel kav tau maj mam thim tawm ntawm keeb kwm theem vim lawv corrosiveness. Cov kav dej yas, cov kav dej sib xyaw, thiab cov kav tooj liab tau dhau los ua cov kav dej hauv cov kav dej. Feem ntau, cov kav hlau stainless muaj qhov zoo dua, tshwj xeeb tshaj yog nyias-walled stainless hlau kav nrog phab ntsa tuab ntawm tsuas yog 0.6-1.2mm. Lawv muaj cov yam ntxwv ntawm kev nyab xeeb, kev cia siab, kev nyiam huv, kev tiv thaiv ib puag ncig, thiab kev siv nyiaj txiag hauv cov dej haus zoo, cov dej kub, thiab cov khoom siv dej uas tseem ceeb rau kev nyab xeeb thiab kev nyiam huv. Lawv tau raug pov thawj los ntawm kev siv engineering hauv tsev thiab txawv teb chaws los ua ib qho zoo tshaj plaws kev ua tiav, tshiab, txuag hluav taws xob, thiab ib puag ncig cov kav dej hauv cov kav dej.
Tam sim no, daim ntawv thov ntawm cov kav dej stainless hlau tau nce qib hauv cov tshuab dej thoob ntiaj teb. Tsis tas li ntawd, cov tsev, cov tsev ua haujlwm, thiab cov chaw kho mob kuj tseem siv cov kav dej tsis muaj steel vim tias nyob rau hauv cov chaw no, qhov dej huv thiab kev nyab xeeb ntawm cov dej yuav tsum tau txiav txim siab ua ntej.
Daim ntawv thov ntawm nyias-walled stainless hlau kav nyob rau hauv txawv teb chaws pib nyob rau hauv 1960s, thiab tsim lub teb chaws kuj tau lug siv nyob rau hauv lub tsev cov dej thiab kev kho mob systems. Tebchaws Askiv, Lub Tebchaws Yelemees, Tebchaws Meskas, thiab Nyij Pooj txhua tus muaj cov qauv rau cov kav hlau xeb, nrog rau cov qauv ISO thiab DIN. ANSI/NSF611997a lub teb chaws tus qauv/National Health Fund thoob ntiaj teb tus qauv tsim los ntawm Tebchaws Meskas raws li Txoj Cai Dej purification tau raug lees paub los ntawm World Health Organization. Cov kav dej thiab cov khoom siv ntawm cov dej haus tam sim no kuj siv cov qauv saum toj no ua lub hauv paus rau kev pov hwm kev noj qab haus huv. Thawj pawg ntawm cov ntaub ntawv uas ua tau raws li qhov yuav tsum tau ua ntawm tus qauv no suav nrog ANSI 304304L, 316, thiab 316L.
Hauv Tebchaws Europe thiab Amelikas, ntau thiab ntau lub tsev thiab tsev siv cov kav hlau tsis muaj steel. Lawv siv 316l ntawm cov khoom siv kub thiab txias txias, thiab siv cov kev sib txuas siab kom sai thiab nyab xeeb rau nruab cov kav hlau stainless thiab cov kav dej. Cov dej xa dej ntawm Detroit Arena hauv Tebchaws Meskas, suav nrog cov kav dej ncaj qha ntawm txhua qhov chaw muag khoom, siv 304 stainless hlau kav. Tom qab ntau tshaj li kaum xyoo ntawm kev sim, cov kav dej faus hauv lub khw Karlskoga hauv Sweden tau hloov los ntawm 316 stainless hlau kav. Tam sim no, cov kav dej tsis muaj steel hlau tau dhau los ua cov khoom siv rau ntau dua 1600 qhov tsim tshiab hauv nroog cov chaw kho dej khib nyiab (WWTPs) hauv Tebchaws Meskas.
Nyiv tau pib txhim kho thiab siv cov kav hlau tsis muaj steel hauv cov tsev nyob rau thaum ntxov xyoo 1970s vim qhov tsis zoo ntawm cov dej haus tsis zoo hauv cov kav dej. Tom qab ntawd nws tau txuas mus rau cov kav dej hauv av hauv 20 xyoo tom qab xyoo 1980, thiab thaj chaw Tokyo tau hloov kho rau cov kav dej. Tsis ntev los no, ntau dua 80% ntawm cov neeg nyob hauv tau hloov cov yeeb nkab hauv qhov qub (cov yeeb nkab sib txuas ntawm cov neeg nyob hauv thiab cov kav dej loj) nrog cov kav dej tsis muaj steel, yog li txo tus nqi xa dej ntawm cov kav dej los ntawm 7.7 thiab txuag dej. Tsis tas li ntawd, nws kuj tau siv dav hauv cov chaw kho dej, cov kav dej txuas hniav, thiab cov choj txuas hniav.
Hauv kev tsim kho cov kav dej kav dej, cov kav dej galvanized tau xaus lawv cov keeb kwm ntev xyoo pua, thiab ntau yam tshiab ntawm cov kav dej yas thiab cov kav dej sib xyaw kuj tau tsim sai heev. Txawm li cas los xij, ntau lub kav dej "tseem muaj qee qhov tsis txaus, nyob deb ntawm qhov ua tau raws li qhov xav tau ntawm cov kav dej xa dej thiab lub teb chaws txoj cai rau cov dej haus thiab dej zoo." Yog li ntawd, cov kws tshaj lij kwv yees tias cov khoom siv ntawm kev tsim kho cov kav dej yuav thaum kawg rov qab mus rau lub sijhawm ntawm cov kav hlau hlau, thiab raws li kev thov txawv teb chaws, cov kav hlau nyias nyias hauv cov kav hlau yuav raug txiav txim siab tias yog ib qho ntawm cov kav dej uas muaj lub zog zoo tshaj plaws. .
Lub sijhawm nce qib thiab daim ntawv thov rau nyias-walled stainless hlau kav hauv Suav teb tau tuaj txog:
Lub durability ntawm ultra-nyias stainless hlau kav tau raug lees paub los ntawm engineering zej zog. Cov neeg tsim khoom hauv Sichuan, Guangdong, Zhejiang, Jiangsu thiab lwm thaj chaw hauv Suav teb tau tsim nws tus kheej tsim kev sib txuas thev naus laus zis thiab kev tsim hluav taws xob, ua rau lawv cov kav dej zoo heev. Muaj cov kws tshaj lij kev lag luam tsim cov kav dej ultra-nyias stainless hlau hauv Sichuan, Guangdong, Zhejiang, Jiangsu thiab lwm qhov chaw, thiab cov khoom lag luam paub tab. Yog li ntawd, lub sij hawm tau los txog rau kev nce qib thiab daim ntawv thov ntawm ultra-nyias stainless hlau kav hauv Suav teb.
Raws li "Ninth Tsib Xyoo Plan" rau kev tsim kho kev lag luam thiab 2010 Lub Hom Phiaj Lub Hom Phiaj, nws kwv yees tias qhov kev xav tau ntawm cov kav dej ntawm xyoo 2001 thiab 2010 yuav yog 500000 txog 600000 km, ntawm qhov kev thov rau cov kav dej txias thiab dej kub hauv tsev. cov tsev yuav yog 400000 km. Txoj kev loj hlob ntawm cov kav dej stainless hlau yog qhov tseem ceeb heev rau kev txhim kho qib ntawm niaj hnub nroog architecture.
Nrog rau txoj kev loj hlob ntawm lub teb chaws kev lag luam, cov kav dej ncaj qha hauv cov nroog xws li Shenzhen thiab Shanghai tau tsim sai heev. Kev lag luam loj hlob hauv nruab nrab lub nroog tseem tab tom npaj thiab ua kom tiav. Nyob rau hauv cov dej haus ncaj qha, cov yeeb nkab stainless hlau series yog undoubtedly ua.
Tam sim no, qee qhov kev lag luam hauv tsev muaj peev xwm tsim tau thiab txuas ntxiv txhim kho nyias-walled stainless hlau kav thiab raj. Lawv tau tsim kev sib koom ua ke ntawm kev sib txuas ntawm nws tus kheej thiab cov khoom siv xws li cov kav dej. Txhim khu kev qha technology, txo cov nqi ntxiv. Qhov no tau tsim muaj txiaj ntsig zoo heev rau kev nce qib, daim ntawv thov, thiab kev txhim kho ntawm nyias-walled stainless hlau kav.
