Chii chinonzi pickling phosphating
Iyo inzira yekurapa pamusoro pesimbi, pickling iko kushandiswa kwehuwandu hweasidhi kuchenesa simbi kubvisa ngura pamusoro.Phosphating ndeyekunyorovesa simbi-yakashambidzwa simbi ine phosphating mhinduro kuumba oxide firimu pamusoro, iyo inogona kudzivirira ngura uye kuvandudza kunamatira kwepende kugadzirira danho rinotevera.

Kunhonga kubvisa ngura nekusvuura ndiyo nzira inoshandiswa zvakanyanya mundima yeindasitiri.Chinangwa chekubvisa ngura uye kubviswa kweganda chinowanikwa nekubviswa kwemagetsi ehydrogen inogadzirwa ne acid dissolution ye oxide uye corrosion.Iyo inonyanya kushandiswa mukunhonga ndeye hydrochloric acid, sulfuric acid uye phosphoric acid.Nitric acid haiwanzo shandiswa nekuti inoburitsa muchetura nitrogen dioxide gasi panguva yekunhonga.Hydrochloric acid pickling inokodzera kushandiswa kune yakaderera tembiricha, haifanire kudarika 45 ℃, kushandiswa kwekusungwa kwe10% kusvika 45%, kunofanirawo kuwedzera huwandu hwakakodzera hweasidhi mhute inhibitor yakakodzera.Sulfuric acid payakadzika tembiricha pickling kumhanya inononoka, inofanirwa kushandiswa mukati metembiricha yepakati, tembiricha ye50 ~ 80 ℃, kushandiswa kwekusungwa kwe10% ~ 25%.Chakanakira phosphoric acid pickling ndechekuti haizoburitse masara ehuori (zvizhinji kana zvishoma pachange paine Cl-, SO42- yasara mushure mehydrochloric acid uye sulfuric acid pickling), iyo isina kuchengetedzeka, asi iyo yakashata yephosphoric acid ndeyekuti iyo mutengo wakakwira, kukurumidza kwe pickling kunononoka, kushandiswa kwakawanda kwe10% kusvika 40%, uye tembiricha yekurapa inogona kunge yakajairika kusvika 80 ℃.Mukuita pickling, kushandiswa kweakasanganiswa asidhi zvakare inzira inoshanda kwazvo, senge hydrochloric-sulfuric acid yakasanganiswa asidhi, phospho-citric acid yakasanganiswa asidhi.Huwandu hwakakodzera hwecorrosion inhibitor hunofanirwa kuwedzerwa ku pickling, kubvisa ngura uye oxidation yekubvisa tangi mhinduro.Kune marudzi akawanda e corrosion inhibitors, uye kusarudzwa kuri nyore, uye basa rayo nderekudzivisa kuparara kwesimbi uye kudzivirira "hydrogen embrittlement".Nekudaro, kana kunhonga "hydrogen embrittleness" inonzwisisika workpieces, kusarudzwa kwecorrosion inhibitors kunofanirwa kungwarira zvakanyanya, nekuti mamwe corrosion inhibitors anodzivirira kuita kwemaatomu maviri ehydrogen mumamorekuru ehydrogen, anoti: 2 [H] → H2↑, kuitira maatomu ehydrogen pamusoro pesimbi inowedzerwa, ichiwedzera "hydrogen embrittleness" maitiro.Naizvozvo, zvinodikanwa kubvunza corrosion data manual kana kuita "hydrogen embrittlements" bvunzo kudzivirira kushandiswa kwengozi corrosion inhibitors.

Kubudirira kweindasitiri yekuchenesa tekinoroji - green laser kuchenesa
Iyo inonzi laser yekuchenesa tekinoroji inoreva kushandiswa kweiyo yakakwira simba laser danda kuvheneka pamusoro peiyo workpiece, kuitira kuti pamusoro petsvina, ngura kana kupfekedza nekukasira kubuda kana kubvisa, kukurumidza-kumhanya uye kunoshanda kubviswa kwechinhu chiri pamusoro. kusungirirwa kana kuvhara pamusoro, kuitira kuti uwane nzira yakachena.Iyo tekinoroji nyowani yakavakirwa pakuita kwekudyidzana kwelaser uye chinhu, uye ine mabhenefiti ari pachena kana ichienzaniswa neyakajairwa nzira dzekuchenesa dzakadai semechani yekuchenesa, kemikari yekuchenesa corrosion, mvura yakasimba yakasimba kuchenesa kuchenesa, yakakwira frequency ultrasonic kuchenesa.Iyo inoshanda, inokurumidza, yakaderera mutengo, diki yekupisa mutoro uye mechanical mutoro pane substrate, uye isingakuvadzi pakuchenesa;Tsvina inogona kudzokororwazve, hapana kusvibisa kwezvakatipoteredza kwakachengeteka uye kwakavimbika, hakukuvadzi hutano hweanoshanda anogona kubvisa zvakasiyana-siyana zvakasiyana-siyana, zvikamu zvakasiyana-siyana zvekuvhara level yekuchenesa maitiro zviri nyore kuwana otomatiki kudzora, kure kure kuchenesa uye zvichingodaro.

Iyo yakasvibira uye kusvibiswa-isina laser yekuchenesa tekinoroji inogadzirisa zvachose kushoropodzwa kwekusvibisa kwezvakatipoteredza kwepickling phosphating kurapwa tekinoroji.Tekinoroji yekudzivirira kwezvakatipoteredza uye girinhi yekuchenesa tekinoroji - "laser kuchenesa" yakatanga uye yakasimuka nemhepo.Tsvagiridzo yayo nekusimudzira uye mashandisiro anotungamira shanduko nyowani yekuchenesa maindasitiri modhi uye kuunza chimiro chitsva kuindasitiri yekurapa kwepasirese.
