Peb yam ntxwv ntawm stainless hlau yeeb nkab: weldability, corrosion kuj thiab polishing kev ua tau zoo (BQ)
Weldability
Cov kev xav tau rau kev ua haujlwm vuam sib txawv rau cov khoom siv sib txawv. Hom tableware no feem ntau tsis xav tau kev ua haujlwm vuam, thiab txawm tias suav nrog qee lub lag luam lauj kaub. Txawm li cas los xij, cov khoom lag luam feem ntau xav tau cov ntaub ntawv raw nrog kev ua haujlwm zoo vuam, xws li chav kawm II tableware, thermos khob, steel yeeb nkab, lub rhaub dej kub, dej dispenser, thiab lwm yam.
Corrosion kuj
Feem ntau ntawm cov khoom siv stainless hlau xav tau zoo corrosion kuj. Stainless hlau kav, xws li chav kawm I thiab II tableware, chav ua noj, lub rhaub dej, haus dej haus, thiab lwm yam., qee cov neeg ua lag luam txawv teb chaws kuj ua cov tshuaj tiv thaiv corrosion ntawm cov khoom: kub cov khoom nrog NaCl aqueous tov rau boiling, ncuav tawm cov tshuaj. Tom qab ib lub sijhawm, ntxuav thiab qhuav, thiab ntsuas qhov hnyav, txhawm rau txiav txim siab qib ntawm corrosion (Ceeb toom: thaum polishing cov khoom, vim muaj cov Fe nyob rau hauv daim ntaub abrasive los yog abrasive daim ntawv, xeb me ntsis yuav tshwm sim nyob rau hauv lub polishing khoom. nto thaum lub sij hawm xeem)
Polishing kev ua tau zoo (BQ)
Tam sim no, cov khoom lag luam stainless hlau feem ntau polished thaum tsim khoom. Tsuas yog ob peb yam khoom, xws li lub tshuab rhaub dej thiab cov tshuab dej, tsis tas yuav polishing. Yog li ntawd, nws yuav tsum tau zoo polishing kev ua tau zoo ntawm raw cov ntaub ntawv. Cov yam tseem ceeb cuam tshuam rau kev ua haujlwm polishing yog raws li hauv qab no:
① Cov khoom tsis zoo ntawm cov khoom siv raw. Xws li khawb, pockmarks, acid pickling, thiab lwm yam.
② Cov khoom siv raw thiab cov khoom siv ntawm cov kav dej stainless hlau. Yog hais tias lub hardness tsawg dhau, nws tsis yooj yim rau polish (BQ cov cuab yeej tsis zoo), thiab yog tias qhov hardness tsawg dhau, cov txiv kab ntxwv tev yog ib qho yooj yim los tshwm rau saum npoo thaum sib sib zog nqus nqus, yog li cuam tshuam rau cov cuab yeej BQ. Cov cuab yeej BQ nrog siab hardness yog qhov zoo.
③ Tom qab kos duab sib sib zog nqus, me me dub me me thiab caij tsheb yuav tshwm sim ntawm qhov chaw ntawm qhov chaw uas muaj deformation zoo, yog li cuam tshuam rau cov cuab yeej BQ.
