Ukwelashwa okungaphezulu kwegiya kucutshungulwa ukuze kuthuthukiswe isimo esingaphezulu sezinto ezibonakalayo.Ngokuvamile, kukhona ukwelashwa okumnyama (i-oxidation ebusweni), ukwelashwa kokugcotshwa okuqinile, ukufakwa kwe-galvanizing, ukwelashwa kwe-phosphorurative, i-chemical silver plating, kanye nokwelashwa kwe-raydent surface.Izimpawu zabo zezimpawu zabo Incazelo imi kanje

1. Ukwelashwa okumnyama (i-oxidation ebusweni):

Ekwelapheni okumnyama kwe-alkaline: Uma ubeka insimbi kusixazululo se-alkaline ku-14ctc, insimbi ngokwayo idlala umphumela wamakhemikhali bese yenza ifilimu yesikhumba esimnyama ebusweni bayo.Ugqinsi lwe-cortex emnyama lungezansi, futhi izithako zamakhemikhali zine-oxidation ye-iron.I-cortex ine-anti-rust effect.

2. Ukwelashwa kokugcotshwa okuqinile:

Vele ufafaze okokugcoba okuqinile ebusweni bezinyo lesondo legiya, kanye nokothambisa okunamathela phezulu ukuze ome ukwenza ifilimu yesikhumba.Izinhlayiya ze-distan sulfide eziqukethwe kuzithako zokugcoba zingena kusishuqulu sensimbi ukuze zidlale umphumela wokugcoba.Ikakhulukazi ekusebenzeni kokuqala kwamagiya noma ukuvimbela umthelela wawo wokugcoba ekuhambeni okuncane okubangelwa ukunyakaza okuncane kokungqubuzana.Ngokuvamile isetshenziswa endaweni lapho amafutha okugcoba angeke asetshenziswe khona

3. Amagalani:

Ukwelashwa okungaphezulu ngenjongo yokuthuthukisa ukusebenza kwensimbi okulwa nokugqwala.Ngokuthuthuka kokwelashwa kwe-rhinate passivation, ukusebenza kokubukeka nakho kuye kwaba ngcono kakhulu.Ugqinsi longqimba lwe-plating luhlukile, ngokuvamile luba ngu-225 μm.

4. Ukwelashwa kwe-Phosphorusization:

Ukwelashwa kwe-phosphate: Insimbi icwiliswa kusisombululo se-phosphate yokushisa ukuze isetshenziswe ngamakhemikhali, ukuze indawo yensimbi yakhe ulwelwesi oluvikelayo lwe-phosphate.Ukumelana nokugqwala kwe-phosphorized cortex kunokumelana okuhle nokuhuzuka kanye nomphumela wokugcoba, ngakho-ke isetshenziswa kakhulu ekwelapheni izingxenye ezishelelayo.

5. I-Chemical silver Plating:

Ukumelana nokugqwala kokumelana namakhemikhali eplating/abrasion kuphezulu, futhi inqubo yesiliva-plated ayidluli ugesi kanye ne-electrolytic.Ifanele imikhiqizo enosayizi ophezulu kanye nezidingo zokunemba kanye nokwakheka okuyinkimbinkimbi.

6. Ukwelashwa kwe-raydent ebusweni:

Ukwelashwa kwe-Raydent kusebenzisa indlela efana ne-electroplating ukuze kukhiqizwe ifilimu ewugqinsi emnyama ene-oxidized engu-1 ~ 2 μm ebusweni bento engumama.Ngoba ifilimu yesikhumba kanye nencwadi ye-T yensimbi, kunzima kakhulu ukuyikhipha.Umthamo wokumelana nokugqwala unamandla/ukumelana nokugqoka uyathuthukiswa, nombala umnyama.

Qaphela:

1. Ithonywa ukuma nobukhulu, i-cortex ayikwazi ukwakheka ngokulinganayo ngaphakathi empandeni yamazinyo.

2. Izikhathi ezihambisanayo ze-ROHS zidinga ukucaciswa ngokucacile ukuze kucaciswe ukuthi ukwelashwa kwe-chromium ene-hexagonal kumele kususwe.
