Puas yuav stainless hlau insulated khob xeb?

Qee cov phooj ywg tau yuav stainless hlau insulated khob thiab pom tias lawv tau xeb tom qab siv lawv rau lub sijhawm. Tsis yog nws hais tias stainless hlau yuav tsis xeb? Cov khoom cuav? Qhov tseeb, nws tsis txhais hais tias stainless hlau insulated khob yuav tsis xeb. Hauv ib puag ncig tshwj xeeb, nws tuaj yeem ua rau lawv xeb.
Stainless hlau muaj peev xwm tiv taus atmospheric oxidation, uas yog, stainless hlau, thiab kuj muaj peev xwm corrode nyob rau hauv xov xwm uas muaj acid, alkali, thiab ntsev, uas yog, corrosion kuj. Tab sis qhov loj ntawm nws cov corrosion kuj txawv nrog cov tshuaj muaj pes tsawg leeg, lub xeev additive, kev siv, thiab ib puag ncig nruab nrab hom ntawm cov hlau nws tus kheej. Zoo li 304 steel yeeb nkab, nws muaj qhov zoo heev corrosion kuj nyob rau hauv qhov chaw qhuav thiab huv si, tab sis thaum tsiv mus rau ntug hiav txwv dej, nws yuav sai sai xeb hauv hiav txwv pos huab uas muaj cov ntsev ntau; Thiab 316 steel kav ua tau zoo. Yog li ntawd, tsis yog txhua hom stainless hlau tuaj yeem tiv taus corrosion thiab xeb hauv ib puag ncig.
Stainless hlau yog nyias, muaj zog, thiab ruaj khov chromium nplua nuj oxide zaj duab xis (cov yeeb yaj kiab tiv thaiv) tsim rau ntawm nws qhov chaw, uas tiv thaiv kev nkag mus ntxiv thiab oxidation ntawm oxygen atoms thiab muab lub peev xwm los tiv thaiv corrosion. Ib zaug rau qee qhov laj thawj, cov yeeb yaj kiab no tsis tu ncua puas, cov pa oxygen atoms hauv huab cua lossis kua yuav tsis tu ncua infiltrate, lossis hlau atoms hauv cov hlau yuav txuas ntxiv sib cais, tsim cov hlau oxide xoob, thiab cov hlau saum npoo yuav raug corroded tsis tu ncua. Hom ntsej muag npog ntsej muag no puas tsuaj rau ntau txoj hauv kev, thiab hom hauv qab no muaj nyob hauv lub neej txhua hnub:
1. Qhov saum npoo ntawm stainless hlau yog them nrog plua plav lossis cov hlau txawv teb chaws uas muaj lwm yam hlau. Nyob rau hauv huab cua ntub, cov dej condensed nruab nrab ntawm cov ntawv txuas thiab cov hlau tsis muaj hlau ua cov roj teeb micro, ua rau cov tshuaj tiv thaiv electrochemical uas ua rau cov yeeb yaj kiab tiv thaiv, hu ua electrochemical corrosion.
2. Organic tshuaj xws li zaub, kua zaub, thiab phlegm adheres rau saum npoo ntawm stainless hlau, tsim cov organic acids nyob rau hauv lub xub ntiag ntawm dej thiab oxygen. Nyob rau tib lub sijhawm, cov organic acids tuaj yeem corrode hlau nto.
3. Qhov saum npoo ntawm stainless hlau adheres rau cov khoom uas muaj acids, alkalis, thiab ntsev (xws li alkali dej thiab txiv qaub dej txaws rau ntawm phab ntsa dai kom zoo nkauj), ua rau lub zos corrosion.
4. Nyob rau hauv cov huab cua phem (xws li huab cua uas muaj ntau cov sulfides, carbon oxides, thiab nitrogen oxides), ntsib cov dej condensed yuav tsim sulfuric acid, nitric acid, thiab acetic acid kua ntsiab lus, ua rau cov tshuaj corrosion.
Tag nrho cov xwm txheej saum toj no tuaj yeem ua rau kev puas tsuaj rau cov yeeb yaj kiab tiv thaiv ntawm cov hlau tsis huv, ua rau xeb. Yog li, thaum peb tsis siv lub thermos ntev, peb yuav tsum ua kom qhuav thiab tsis txhob khaws cov dej qab zib xws li yogurt thiab dej ntsev kom ntau li ntau tau los tiv thaiv corrosion ntawm phab ntsa sab hauv ntawm lub thermos.
