Puas yog txias- dov coils yuav tsum tau qhuav tom qab passivation?

1.Vim li cas thiaj ua kom qhuav yog ib kauj ruam tseem ceeb?

Xyuas kom tsim thiab kho ntawm Passivation Film:

Cov tshuaj passivation ua rau nyias nyias, noo noo -muaj, gel-zoo li zaj duab xis nascent ntawm daim kab xev. Drying (using hot air) removes free water and water of crystallization from this film, transforming it into a dense, stable, and strongly adhesive solid protective film.

Ib zaj duab xis ntub dej tsis muaj zog muaj lub cev tsis tshua muaj zog thiab yooj yim wiped tawm los yog puas thaum lub sij hawm tom ntej winding thiab tsheb thauj mus los.

Tiv thaiv "Watermark Rust" thiab "White Rust":

Qhov no yog qhov txaus ntshai tshaj plaws. Yog tias tsis muaj dej noo (tshwj xeeb tshaj yog cov yeeb yaj kiab dej) muaj nyob rau ntawm daim kab xev los yog nruab nrab ntawm cov txheej coil, cov dej noo tsis tuaj yeem evaporate tom qab winding, sai sai ua rau cov dej stains los yog loj heev - cheeb tsam electrochemical corrosion (dawb xeb) ntawm cov hlau phaj.

Lub hom phiaj ntawm kev kho mob passivation yog tiv thaiv xeb; Yog hais tias xeb tshwm sim vim tsis tiav ziab, thawj lub hom phiaj ntawm cov txheej txheem yog kiag li swb.

Tsis txhob cuam tshuam cov tshuaj sib npaug ntawm cov tshuaj passivation:

Cov kua dej uas muaj nyob hauv yuav txuas ntxiv yaj thiab dilute tus neeg sawv cev passivating, uas ua rau muaj qhov tsis sib xws ntawm cov yeeb yaj kiab passivation, tsis ua haujlwm, lossis cov tshuaj tiv thaiv ntau dhau, cuam tshuam rau nws qhov sib xws thiab kev tiv thaiv kev ua haujlwm.

2.Dab tsi yog cov kauj ruam ziab hauv cov txheej txheem ntws?

Cov cuab yeej ziab khaub ncaws: Feem ntau siv lub tshuab ziab khaub ncaws ua haujlwm siab -(xws li lub thawv cua kub txau), uas sai sai evaporates tag nrho cov noo noo los ntawm cov kab nrib pleb los ntawm tshuab cua sov (kub, airflow, thiab ceev yog adjustable).

Tswj Tsis Siv Neeg: Kev ziab kub thiab lub sij hawm yuav tsum tau ua kom zoo raws li cov kab ntau lawm ceev, passivation tov hom, thiab sawb thickness kom ntseeg tau tias cov sawb saum npoo kub nce mus txog saum cov lwg taw tes thiab qhuav tag thaum nws tawm hauv lub tshuab ziab khaub ncaws.

3.Dab tsi yog qhov tsim nyog kom qhuav cov kauj ruam?

Qhuav tom qab passivation tsis yog ib qho kev xaiv, tab sis yog ib qho tseem ceeb ntawm cov txheej txheem los xyuas kom meej qhov ua tau zoo ntawm cov txheej txheem passivation.

4.Dab tsi yog lub luag haujlwm ua kom qhuav?

Nws ua kom qhov zoo kawg nkaus ntawm kev kho deg (pickling, yaug, passivation) thiab lav qhov ruaj khov ntawm cov khoom ua ntej khaws cia thiab kev thauj mus los.

 

5.Dab tsi yog cov ntsiab lus zoo?

Kev ziab tsis tiav yog ib qho ntawm feem ntau ua rau xeb tsim ntawm passivated coils nyob rau lub sij hawm luv luv. Thaum lub sijhawm tshuaj xyuas ntau lawm, ntxiv rau kev kuaj xyuas qhov hnyav ntawm cov yeeb yaj kiab passivation, nws kuj tseem yuav tsum tau kuaj xyuas seb qhov saum npoo puas qhuav tag.
