Pickling:
Zvinoenderana nekumwe kusungwa, tembiricha uye kumhanya, asidhi inoshandiswa kubvisa iron oxide ganda kemikari, inonzi pickling.
Phosphating:
Maitiro ekugadzira phosphate coating pane simbi pamusoro kuburikidza nemakemikari uye electrochemical reaction.Iyo yakaumbwa phosphate inoshandura firimu inonzi phosphating firimu.
Chinangwa: Kuwedzera anti-corrosion uye anti-rust zvimiro zvepamusoro pechinhu.Panguva imwecheteyo, iyo phosphate firimu yakaumbwa semutakuri wekuzora ine maitiro akanaka nerubricant uye inoderedza iyo yepamusoro friction coefficient yekutevera kugadziridzwa kwezvinhu.Kuvandudza kunamatira kwepende uye gadzirira danho rinotevera.
Saponification:
Mushure mekunge workpiece iri phosphating, iyo stearate uye zinc phosphate film layer mune mhinduro yakanyudzwa mu saponification bath inoita kuti iite zinc stearate saponification layer.Chinangwa: Kugadzira saponification layer ine yakanakisa adsorption uye lubricity pamusoro pechinhu, kuitira kufambisa kufambira mberi kwakanaka kweinotevera kugadzirisa tekinoroji.
Iyo nzira yepickling rust uye chiyero ndiyo inonyanya kushandiswa nzira mumunda weindasitiri.Chinangwa chekubvisa ngura uye oxide chikero chinowanikwa nemuchina wekubvisa asidhi pane oxide dissolution uye corrosion kugadzira hydrogen gasi.Iyo inonyanya kushandiswa mukunhonga ndeye hydrochloric acid, sulfuric acid, uye phosphoric acid.Nitric acid haiwanzo shandiswa nekuti inoburitsa muchetura wenitrogen dioxide gasi panguva yekunhonga.Hydrochloric acid pickling inokodzera kushandiswa pane tembiricha yakaderera, haifanirwe kudarika 45 ℃, inofanirawo kuwedzera huwandu hwakakodzera hweasidhi mhute inhibitor.Iko kukurumidza kunyura kwe sulfuric acid pakupisa kwakadzika kunonoka, yakakodzera kushandisa pane tembiricha yepakati, tembiricha 50 - 80 ℃, shandisa 10% - 25%.Chakanakira phosphoric acid pickling ndechekuti haizoburitse masara ehuori, ayo akachengeteka, asi kushata kwephosphoric acid kudhura kwakanyanya, kunonoka kutora kukurumidza, kushandiswa kwese kuri kuita 10% kusvika 40%, uye tembiricha yekugadzira inogona normal tembiricha kusvika 80 ℃.Mukuita pickling, kushandiswa kweakasanganiswa asidhi zvakare inzira inoshanda kwazvo, senge hydrochloric acid-sulfuric acid yakasanganiswa asidhi, phosphoric acid-citric acid yakasanganiswa asidhi.
Mutsetse wekunhonga wakagadzirwa neWuxi T-control wakavharirwa zvizere uye otomatiki.Iyo nzira yekugadzira inoitwa mune yakavharwa tangi uye yakasarudzika kubva kunze kwenyika;iyo acid mhute inogadzirwa inotorwa neiyo acid mhute shongwe yekunatsa kurapwa;maitiro ekugadzira akaparadzaniswa kubva kune hutano hweanoshanda Impact;otomatiki kudzora, kugadzirwa kwakanyanya, kuburitsa kukuru, kunyanya kwakakodzera kuburitsa hombe, kugadzirwa kwepakati;komputa otomatiki kutonga kwemaitiro paramita, yakagadzikana kugadzirwa maitiro;zvichienzaniswa neyakapfuura pickling phosphating yekugadzira mutsara, yakanyanya kuvandudza mashandiro, asiwo zvakanyanya Nyika inoderedza kusvibiswa kune zvakatipoteredza.
