Fosphate Coatings Mu'ai Togafitiga mo La'au Uamea

O le mua'i togafitiina mo mea uamea a'o le'i fa'aogaina le pauta o le phosphating lea e mafai ona fesuisuiai i le mamafa o le ufiufi.

O le sili atu o le mamafa o le paʻu o le liua o le maualuga lea o le maualuga o le faʻafefeteina e maua; o le maualalo o le mamafa o le ufiufi o le sili atu lea o mea tau masini.

O lea e tatau ai ona filifili se fetuunaiga i le va o mea faʻainisinia ma le faʻafefe. O le mamafa o le faʻapipiʻiina o le phosphate e mafai ona faʻalavelave ai efuefu ufiufi i lena gau tioata e mafai ona tupu pe a oʻo i le faʻapipiʻiina i le faʻaogaina o malosiaga faʻainisinia, faʻataʻitaʻiga. punou po'o le a'afiaga.

Ona o le faʻapipiʻiina lelei o le paʻu paʻu i le phosphate coating, o le faʻamavaega e masani lava ona tupu i le phosphate / metal substrate interface nai lo le phosphate / paʻu faʻapipiʻi atinaʻe.

Fosphate coatings e ufiufi e BS3189/1959, Vasega C mo zinc phosphate ma Vasega D mo uʻamea phosphate.
O se saito lelei tioata zinc phosphate e fautuaina i le mamafa o le ufiufi o le 1-2g/m2 ma mo le u'amea phosphate i le 0.3-1g/m2. E mafai ona fai le fa'aoga e ala i le fa'asuina pe lofu. Chromate passivation e le masani ona manaʻomia.

O fa'alavalava u'amea phosphate e masani ona fa'aoga ile tolu pe fa fa'agaioiga. O le galuega e masani lava ona pasia ni vaega vai e lua a'o le'i fa'amago.

Zinc phosphate e mafai ona fa'apipi'i pe fufui i se fa'agaioiga e lima, ie. alkali degrease, fufulu, zinc phosphate, lua vai vai.

E taua tele le faʻapipiʻiina o le mea faigaluega pe a uma le phosphating i se taimi vave e mafai ai pe a uma ona faʻagogo.
