Unyango oluphezulu lwegiya lucutshungulwa ukuphucula umgangatho wezinto eziphathekayo.Ngokubanzi, kukho unyango olumnyama (i-oxidation yomphezulu), unyango lokuthambisa oluqinileyo, ukugalela, unyango lwe-phosphorurative, i-chemical silver plating, kunye nonyango lwe-raydent surface.Iimpawu zabo zeempawu zabo Inkcazo ngolu hlobo lulandelayo

1. Unyango olumnyama (i-oxidation yomhlaba):

Ngonyango olumnyama lwe-alkaline: Xa ubeka isinyithi kwisisombululo sonyango lwe-alkaline kwi-14ctc, isinyithi ngokwaso sidlala umphumo wekhemikhali kwaye senze ifilimu yesikhumba esimnyama ebusweni bayo.Ubukhulu be-cortex emnyama bungezantsi, kwaye izithako zemichiza zine-iron oxidation.I-cortex ine-anti-rust effect.

2. Unyango lokuthambisa oluqinileyo:

Ukutshiza nje i-lubricant eqinileyo kumphezulu wezinyo levili legiya, kunye ne-lubricant ebambelela kumphezulu ukuze yome ukwenza ifilimu yolusu.I-distan sulfide particles eziqulethwe kwizithako ze-lubricant zingena kwizicubu zetsimbi ukuze zidlale umphumo wokuthambisa.Ngokukodwa ekusebenzeni kokuqala kweegiya okanye ukuthintela ifuthe layo lokuthambisa kwi-micro-movement ebangelwa ziintshukumo ezincinci zokukhuhlana.Ngokuqhelekileyo isetyenziswe kwindawo apho ioli yokuthambisa ingasetyenziswa

3. Iigalvanized:

Unyango lwangaphezulu ngenjongo yokuphucula ukusebenza kwe-anti-rust yesinyithi.Ngokuqhubela phambili kwonyango lwe-rhinate passivation, ukusebenza kwenkangeleko kuphuculwe kakhulu.Ubunzima bomgangatho wokutya bahlukile, ngokubanzi malunga ne-225 μm.

4. Unyango lwe-Phosphorusization:

Kunyango lwe-phosphate: Isinyithi sintywiliselwa kwisisombululo se-phosphate yokufudumeza kunyango lwekhemikhali, ukuze umphezulu wesinyithi wenze i-membrane ekhuselayo ye-phosphate.Ukumelana ne-anti-rust ye-cortex ye-phosphorized inokumelana ne-abrasion efanelekileyo kunye nefuthe lokuthambisa, ngoko ke isetyenziswa kakhulu kunyango lweendawo ezityibilikayo.

5. Ukufakwa kwesilivere ngekhemikhali:

Ukuxhatshazwa kwe-corrosion of chemical plating / abrasion resistance is high, kwaye inkqubo yesilivere-plated ayidluli umbane kunye ne-electrolytic.Ifanelekile kwiimveliso ezinobungakanani obuphezulu kunye neemfuno ezichanekileyo kunye nemilo enzima.

6. Unyango lomphezulu weraydent:

Unyango lwe-Raydent lusebenzisa indlela efana ne-electroplating ukuvelisa ifilimu eyi-1 ~ 2 μm engqindilili emnyama ecocekileyo ecocekileyo kumphezulu wezinto ezingumama.Ngenxa yokuba ifilimu yesikhumba kunye nencwadi ye-T yensimbi, kunzima kakhulu ukuyikhupha.Umthamo wokuxhathisa umhlwa unamandla / ukunxiba -umthamo onganyangekiyo uyaphuculwa, kwaye umbala umnyama.

Phawula:

1. Ichaphazeleka ngokumila kunye nobukhulu, i-cortex ayikwazi ukubunjwa ngokulinganayo ngaphakathi kweengcambu zamazinyo.

2. Izihlandlo ezihambelanayo ze-ROHS kufuneka zicaciswe ngokucacileyo ukucacisa ukuba unyango lwe-chromium ene-hexagonal kufuneka lususwe.
