La dhajiyay 2015-11-23Daahan Dacromet waxaa loola jeedaa daahan aqueous zinc chromium daahan, daahan quusin, cadayashada ama buufinta qaybaha birta ama qaybaha dusha, sameeyay by dubay si ay u jajabiso zinc iyo chromate zinc oo ah qaybta ugu muhiimsan ee lakabka ka-hortagga daxalka ee aan noolaha ahayn.
Tilmaamaha ugu muhiimsan: 1. Iska caabbinta daxalka oo aad u xooggan
Marka la eego tiro isku mid ah oo daahan ah, daahan zinc chromium ee badda kulaylaha qoyan iyo xaaladaha atmospheric warshadaha, waxqabadka ilaalinta ee dajinta zinc sare, dahaadhay cadmium, maquufin kulul galvanized lakabka ilaalinta dhowr jeer iyo xataa dhowr jeer.
2.ma soo saari doono hydrogen ebrittlement
Ilaalinta dusha sare waxay ku habboon tahay xoogga xajinta ee Rm oo leh in ka badan 1000N / mm2 boolal xoog leh, ilo iyo qaybo kale oo ka mid ah birta noocaan ah.
Sifooyin kale:
1 rinji wanaagsan
2 in aan wasakhayn deegaanka
3 caabbinta kulaylka wanaagsan
4 adhesion sare
5 oo leh saxnaan wanaagsan
Sifooyin kale: 1. Rinjiga wanaagsan2. Wax wasakh ah oo deegaanka ah oo aan wasakhayn 3. Iska caabbinta kulaylka wanaagsan4. adhesion sare5.
