Zvakanakira uye Zvakaipa zveTrivalent Chromium Plating

Kutanga, chii chinonzi Trivalent?

Zviri akushongedza chrome plating, iyo inogona kupa scratch uye corrosion kuramba mumhando dzakasiyana dzemavara.Trivalent chromeinoonekwa seye eco-inoshamwaridzika imwe kune hexavalent chromium.

Tevere, Ngatitarisei zvakadzama maitiro aya kuti tinzwisise mabhenefiti ayo uye zvipingamupinyi.

Zvakanakira:

Zvakanakira zvetrivalent chromium maitiropamusoro peiyo hexavalent chromium maitiro kune zvishoma zvinonetsa kwezvakatipoteredza nekuda kwekuderera kwehuturu hwe trivalent chromium, kugadzirwa kwepamusoro, uye kuderera kwemitengo yekushandisa.

Muchikamu chechromium chetatu, hexavalent chromium inosvibisa yekugezera yekugezesa.Naizvozvo, iyo yekugezera haina chero huwandu hunoyemurika hwehexavalent chromium.Iyo yakazara chromium kuungana kwe trivalent chromium mhinduro inosvika chikamu chimwe muzvishanu icho chehexavalent chromium mhinduro.

Nekuda kwekemikari yetrivalent chromium electrolyte, kutadza hakuitike panguva yekuputira sezvakunoita panguva yehexavalent chromium plating.Kushandiswa kwe trivalent chromium zvakare kunoderedza matambudziko ekurasa marara nemitengo.

Zvakaipa:

Izvo zvakashata zveiyo trivalent chromium process ndezvekuti maitiro acho anotarisisa kusvibiswa kupfuura hexavalent chromium process, uye trivalent chromium process haigone kurongedza huwandu hwakazara hweplate ukobvu hunogona kuita hexavalent chromium process.Nekuti inonzwa nekusvibiswa, iyo trivalent chromium process inoda kunyatsogeza uye kusimba murabhoritari kudzora kupfuura zvinoita hexavalent chromium process.Trivalent chromium yekugezera inogona kukora kweplate kunosvika 0.13 kusvika 25 µm.Haikwanise kushandiswa kune yakawanda yakaoma chromium plating application.

Trivalent chromium electroplating yekugezera yakagadziridzwa kunyanya kutsiva yekushongedza hexavalent chromium plating yekugezera.Magadzirirwo ekugeza ane matrivalent aratidza kuve akaoma nekuti trivalent chromium inonyungudika mumvura kuita maion akagadzikana asingakurumidzi kuburitsa chromium.Parizvino, pane mhando mbiri dze trivalent chromium maitiro pamusika: single-sero uye kaviri-sero.Misiyano mikuru mumatanho maviri ndewekuti iyo kaviri-sero process solution ine ishoma-ku-hapana chlorides, nepo imwe-sero process solution ine yakanyanya kuwanda kwekloridi.

Pamusoro pezvo, iyo maviri-sero maitiro anoshandisa lead anode anoiswa mumabhokisi eanode ane dilute sulfuric acid solution uye akaiswa mukati memembrane inopindika, nepo imwe-sero process inoshandisa kabhoni kana graphite anode inoiswa pakatarisana nayo. mhinduro yeplating.Ruzivo nezvemaitiro aya haawanikwe nekuti trivalent chromium yekugezera parizvino pamusika ndeyamuridzi.

Heano maitiro makuru eTrivalent chrome:

· Hushamwari pazvakatipoteredza-utsi hune muchetura hushoma pane plating ine hexavalent

· Mushoma tsvina tsvina

· Mari yekuchenesa mvura yakaderera

· Mitemo yekuyedza mishoma uye mitengo yakabatana

The drawbacks ndeiyi inotevera:

· Mutengo wakakwira zvishoma pamakemikari & kugadzirisa kusiyana nehexavalent plating.

· Kuoma mukusarudza anode

· Complex mhinduro kuumbwa

· Kuomerwa coating ukobvu kuwedzera
