Zinc phosphate uye mashandisirwo ayo

Generally zinc phosphate conversion coating inoshandiswa kupa kuchengetedzwa kwekugara kwenguva refu. Anenge ese maindasitiri emotokari anoshandisa rudzi urwu rwekushandura coating. Izvo zvakakodzera kune zvigadzirwa zvinosangana nemamiriro okunze akaoma. Coating quality iri nani pane iron phosphate coating. Iyo inoumba 2 - 5 gr/m² coating pamusoro pesimbi pamusoro kana yakashandiswa pasi pepende. Kushandisa, kuseta uye kutonga kwemaitiro aya kwakaoma kupfuura dzimwe nzira uye zvinogona kuiswa nekunyudza kana kupfapfaidza.

Organic makomisheni senge nickel uye manganese anowedzerwa mubhavhu kuti awedzere kuita kwekuputira. Zvakare activation inogona kushandiswa kugadzira diki phosphate makristasi pane simbi pamusoro pamberi zinc phosphating.
Zinc phosphate reaction inoitika mune amorphous shape ine grey - dema ruvara.
pH optimizers inowedzerwa kuti ikurumidze kuita. Tembiricha, nguva yekushandisa, kutarisisa, pH, yakazara asidhi uye yemahara acid kukosha ndiwo maparamita anofanirwa kunge ari pasi pekutonga.

Zinc phosphates, coating range pakati pe7 – 15 gr/m², inoshandiswa mukudhirowa waya, kudhirowa kwechubhu uye maindasitiri anotonhora ekugadzira. Phosphated metal workpieces inogadzirirwa kune inotevera nhanho nekushandiswa kweanodzivirira lubricans uye sipo.
