Raws li cov ntaub ntawv los ntawm Tuam Tshoj Chain Store & Franchise Association, tus nqi pov tseg zaub mov hauv cov chaw lag luam ncav cuag 8% - 12%. Txawm li cas los xij, cov tub yees stainless hlau zoo tuaj yeem ntev lub sijhawm tshiab ntawm cov zaub mov khov los ntawm ntau dua 30% thiab txo tus nqi pov tseg rau hauv qab 5%. Tshwj xeeb tshaj yog tawm tsam keeb kwm yav dhau los ntawm kev lag luam zaub mov ua ntej loj hlob ntawm tus nqi txhua xyoo ntawm ntau dua 20%, ua ib qho khoom siv tseem ceeb rau kev khaws cia kub qis, nws muaj feem cuam tshuam ncaj qha rau qhov zoo ntawm zaub mov thiab cov kab hauv qab ntawm kev nyab xeeb zaub mov, ua tus neeg nqa khoom tseem ceeb rau kev txhim kho kev ua haujlwm hauv chav ua noj.
Yuav tsum xyuam xim dab tsi thaum yuav cov khoom siv stainless hlau hauv khw?
Yuav tsum tau ua tib zoo saib xyuas qhov zoo thiab kev ua haujlwm ntawm cov khoom siv tub yees. Feem ntau, kev txiav txim siab tuaj yeem ua los ntawm cov txiaj ntsig thiab cov yam ntxwv ua haujlwm ntawm cov khoom siv. Cov hauv qab no yog cov ntaub ntawv qhia txog qhov zoo:
(1) Qhov Zoo Tshaj Plaws ntawm Kev Tiv Thaiv Kev Kub Ntxhov uas Tsis Hloov Tau
Chav ua noj ua haus muaj av noo thiab muaj roj, roj, kua qaub, thiab alkalis ntau. Cov txee ua los ntawm cov hlau txias dov yooj yim yuav xeb thiab xeb. Qhov sib txawv, cov txee ua los ntawm SUS304 stainless hlau qib zaub mov tuaj yeem tiv taus 500 teev yam tsis muaj xeb hauv kev sim ntsev tsuag uas tau teev tseg hauv GB / T 4334.5 - 2015. Lawv tuaj yeem tswj lawv qhov chaw kom zoo txawm tias tom qab kov ntev nrog cov txuj lom hauv chav ua noj xws li kua ntses thiab kua txiv hmab txiv ntoo. Lub neej ua haujlwm ntawm cov txee no tuaj yeem ncav cuag 10 - 15 xyoo, yuav luag ob npaug ntawm cov ntaub ntawv ib txwm muaj, txo cov nqi kho dua tshiab ntawm cov khoom siv.
(2) Cov Khoom Tua Kab Mob
Txhawm rau kom muaj zog tiv thaiv kab mob zaub mov, cov tub yees stainless hlau zoo txhim kho lawv cov teebmeem tua kab mob los ntawm cov thev naus laus zis xws li nano-silver coatings thiab cordierite ceramic liners. Piv txwv li, tus qauv Haier BC/BD - 300GHPT tau raug sim kom muaj tus nqi tua kab mob ntawm 99.99% tawm tsam Escherichia coli thiab Staphylococcus aureus. Lub qhov rooj gaskets kuj tseem tuaj yeem tiv thaiv rau hom pwm, suav nrog Aspergillus niger. Cov cuab yeej no txo qhov kev pheej hmoo ntawm kev sib kis ntawm cov zaub mov hauv tsev neeg los ntawm 60%, ua tau raws li cov kev cai ntawm National Food Safety Standard rau Kev Huv Si ntawm Kev Tua Kab Mob Hauv Rooj Noj Mov, thiab dhau los ua qhov kev lees paub tseem ceeb rau kev ua raws li kev noj haus.

Cov tub yees stainless hlau muaj lub zog compressive ntau dua 200MPa thiab tsis muaj kev pheej hmoo ntawm kev ntsws lossis deformation hauv qhov chaw kub qis. Nrog rau kev tsim qauv modular, kev siv qhov chaw tuaj yeem nce ntxiv 25%. Kev siv cov qauv tub rau khoom tiered txhim kho kev nkag mus rau zaub mov kom zoo dua 40%. Lawv sib xyaw ua ke nrog chav ua noj tag nrho. Xyoo 2024, feem ntawm kev ua lag luam ntawm cov khoom lag luam no tau txog 23.8%, ob npaug piv rau xyoo 2019.
(4) Yooj yim ntxuav
Tsim los ua kom tau raws li qhov xav tau ntawm kev siv ntau zaus ntawm chav ua noj ua lag luam, tag nrho lub txee muaj qhov chaw ua los ntawm cov hlau tsis xeb nrog qhov du ntawm Ra≤0.8μm, thiab tus nqi roj seem tsawg dua 3%. Nws tuaj yeem ntxuav sai sai nrog cov tshuaj ntxuav tsis muaj teeb meem yam tsis tas yuav tsum tau saib xyuas. Cov ntaub ntawv sim qhia tau tias lub sijhawm ntxuav yog 50% tsawg dua li ntawm cov iav liners, thiab qhov chaw tseem tiaj tus tsis muaj khawb seem txawm tias tom qab 1,000 daim ntaub so, hloov kho zoo rau cov yam ntxwv ntawm cov roj ntau thiab kev ntxuav ntau zaus hauv chav ua noj.
Kev Cia Siab Yav Tom Ntej
Kev lag luam noj mov tab tom nrawm nrawm rau kev siv hluav taws xob zoo thiab kev txawj ntse. Tus qauv tshiab hauv tebchaws GB 12021.2 – 2025, uas yuav siv rau xyoo 2026, yuav ua kom nruj dua qhov kev txwv kev siv hluav taws xob rau cov tub yees thiab cov tub yees khov los ntawm ηs≤70% mus rau ηt≤40%, nce 42.9%, thiab xav tias yuav tshem tawm 20% ntawm cov khoom siv hluav taws xob ntau. Lub caij no, qhov nkag mus ntawm cov tub yees khov ntse yuav tshaj 38% hauv xyoo 2025. Cov haujlwm xws li kev tswj kub IoT thiab kev saib xyuas kev siv hluav taws xob yuav dhau los ua cov yam ntxwv txheem. Qhov loj me ntawm kev ua lag luam ntawm cov qauv ua hauv yuav ncav cuag 16.23 billion yuan. Kev siv cov tshuaj txias uas tsis muaj kuab paug rau ib puag ncig thiab cov thev naus laus zis hloov pauv tau txo qhov kev siv hluav taws xob nruab nrab ntawm kev lag luam los ntawm 22% piv rau xyoo 2019.
Cov kev ceev faj
Kev saib xyuas yuav tsum ua raws li cov ntsiab cai ntawm "tiv thaiv kev xeb, tiv thaiv lub foob, thiab tswj qhov kub." Rau kev ntxuav txhua hnub, siv daim ntaub mos mos nrog cov tshuaj ntxuav tsis muaj zog thiab tsis txhob siv cov khoom tawv xws li cov hlau los tiv thaiv kev khawb.
So cov gaskets qhov rooj nrog dej sov ib zaug ib lub lim tiam kom tswj tau lawv qhov kev ua haujlwm sealing, uas tuaj yeem txo qhov poob txias los ntawm 15%. Nws raug pom zoo kom kuaj xyuas cov qhov txias ntawm lub compressor txhua rau lub hlis thiab muaj kev saib xyuas tshaj lij ib zaug ib xyoos.
Yuav tsum nco ntsoov tias cov khoom noj uas muaj kua qaub yuav tsum tsis txhob kov ncaj qha rau lub txee. Thaum yaj ntawm qhov kub qis, qhov kub hloov pauv yuav tsum tsis pub tshaj ± 5 ° C kom tiv thaiv cov dej noo kom tsis txhob ua rau xeb.
