Phosphating pretreatment line yesimbi zvikamu kana welded parts

Iron phosphate ndiyo inonyanya kushandiswa pretreatment yeupfu yekupotera nekuti inogona kushandiswa neinenge chero chinhu uye ine zvakatipoteredza zvine hushamwari bi-zvigadzirwa kana sludge. Iyi nzira inowanzoshandiswa pazvinhu zvesimbi.

Zinc phosphate isiri-metallic, crystalline coating iyo inonyanya kuomerera kune zvinhu. Zvakakosha kucherechedza, zinc phosphate inobuda kubva kune mhinduro pachayo, kwete kubva kune chikamu chepamusoro senge iron phosphate coating. Zinc phosphate makristasi anotanga kuumba panzvimbo yeanodic pane chikamu chepamusoro uye anomira kuumba kana chikamu chepamusoro chapedzwa, kureva. vakarova imwe crystal. Kusiyana nesimbi phosphate, zinc phosphate haigoni kuchenesa uye kupfeka panguva imwe chete: saka, nhanho ina-kushambidza, sukurudza, zinc phosphate, sukurudza ndeye yakajairika setup. Nepo zinc phosphating ichipa yakagadziridzwa coating adhesion zvivakwa, zvirinani kupfekedza munzvimbo dzakasimba uye zvirinani kuramba corrosion, maitiro acho ane mutengo wepamusoro wekushandisa, anoshandisa simbi dzinorema, uye anogona kuburitsa dhaka rakati wandei, pasina imwe ine hushamwari hwezvakatipoteredza nechinangwa chekurasa. Zinc phosphate inowanzo shandiswa pane galvanized simbi zvinhu.

Chromium phosphate inonyanya kushandiswa kune aruminiyamu alloy based parts. Nepo maitiro aya achibudirira, sezinc phosphate, inoshandisa simbi dzinorema dzinoda kudzoserwa kuti dziraswe zvine hushamwari.

Kudzora iyo phosphating maitiro kwakakosha kuti uwane inopindirana coatings izvo zvinozoguma nekugadzikana kwekupfeka maitiro. Iwo akanyanya kukosha maitirwo ekudzora muphosphate shanduko coating ndeaya:

Nguva - iyo yakareba nguva yekusangana iyo yakawanda nguva yekuita makemikari, maitiro acho anofanira kunge akareba zvakakwana kuti abvumire chemistry kuumba yunifomu yejasi.

Tembiricha - makemikari anowanzo kuve ane hutsinye pane yakakwirira tembiricha

Concentration uye pH - iyo yakawanda asidi mukugadzirisa inomhanyisa maitiro ekuputira uye inogona kukonzera huremu huremu hwekuvhara.
