Iko kurapwa kwepamusoro kwegiya kunogadziriswa kuti ivandudze mamiriro epamusoro ezvinyorwa.Kazhinji, kune vatema kurapwa (pamusoro oxidation), yakasimba lubrication kurapwa, galvanizing, phosphorurative kurapwa, kemikari sirivha plating, uye raydent pamusoro kurapwa.Vavo hunhu hwehunhu hwavo. Tsananguro ndeyotevera

1. Kurapa kwakasviba (pamusoro oxidation):

Kurapwa kwealkaline dema: Pakuisa simbi mune alkaline kurapwa mhinduro kune 14ctc, simbi pachayo inoridza kemikari uye inoita dema reganda firimu pamusoro payo.Ukobvu hweblack cortex huri pazasi, uye makemikari zvinongedzo zvina -iron oxidation.Iyo cortex ine anti-rust effect.

2. Solid lubrication kurapwa:

Ingopfapfaidza lubricant yakasimba pamusoro pevhiri zino regiya, uye lubricant inonamatira kumusoro kuti iome kuita firimu reganda.Iyo distan sulfide zvimedu zviri mumafuta ekuzora zvinopinda mukati mesimbi tishu kuti itambe lubrication maitiro.Kunyanya mukutanga kumhanya kwemagiya kana kudzivirira kudzora kwayo pamicro-kufamba kunokonzerwa nediki friction mafambiro.Kazhinji inoshandiswa munzvimbo iyo mafuta ekuzora asingagoni kushandiswa

3. Galvanized:

Kurapa kwepamusoro kwechinangwa chekuvandudza anti-rust kuita kwesimbi.Nekufambira mberi kwe rhinate passivation kurapwa, kuita kwechitarisiko kwakavandudzawo zvakanyanya.Ukobvu hweiyo plating layer yakasiyana, kazhinji inenge 225 μm.

4. Phosphorusization kurapwa:

Pakurapa phosphate: Simbi inonyudzwa muinodziya phosphate mhinduro yemakemikari kurapwa, kuitira kuti simbi pamusoro iite phosphate inodzivirira membrane.Iyo anti-rust kuramba yephosphorized cortex ine yakanaka abrasion kuramba uye lubrication maitiro, saka inonyanya kushandiswa mukurapa kwezvikamu zvinotsvedza.

5. Kemikari sirivha plating:

Kupokana kwekuora kwemakemikari plating / abrasion kuramba kwakakwira, uye sirivheri-plated process haipfuure magetsi uye electrolytic.Inokodzera zvigadzirwa nehupamhi hwepamusoro uye nekururama zvinodiwa uye maumbirwo akaoma.

6. Raydent surface treatment:

Raydent kurapwa kunoshandisa nzira yakafanana neye electroplating kugadzira 1 ~ 2 μm gobvu dema oxidized neat firimu pamusoro pechinhu chaamai.Nokuti firimu reganda uye simbi T bhuku, zvakaoma zvikuru kubvisa.Iyo ngura yekudzivirira simba yakasimba / kupfeka -resistant kugona inovandudzwa, uye ruvara rwakasviba.

Cherechedza:

1. Inobatwa nechimiro uye ukuru, cortex haigoni kuumbwa zvakafanana mukati memudzi wemeno.

2. Nguva dzinoenderana dzeROHS dzinoda kujekeswa kutsanangura kuti kurapwa kwehexagonal chromium kunoda kubviswa.
