PPGI uamea u'amea ma Vaious lanu ma Zinc Layer
Fa'amatalaga o oloa
Uila Umea Fa'amea Fa'aula'i Fa'atasi ma Fa'ailoga Lanu RAL uma o se 'u'amea lea e fa'apipi'i ai se mea fa'apipi'i (fa'ata'ita'iga vali, ata...) e fa'apipi'i vili'. A fa'apipi'i i luga o le u'amea, o le mea fa'apipi'i (i le vai, fa'apipi'i po'o le pa'u pa'u) e fausia ai se ata e iai le puipuiga, teuteu ma/po'o isi mea fa'apitoa.
I le 40 tausaga, ua faʻateleina le gaosiga o uʻamea a Europa i le 18.
Uamea
O le filifiliga o mea u'amea e fa'atatau i le tele, masini ma mea e tete'e ai le pala e mana'omia mai le oloa fa'apipi'i o lo'o fa'aogaina. O mea e sili ona taatele o mea uʻamea e faʻapipiʻiina faʻaletino o:
★ u'amea u'amea vevela (HDG) lea e aofia ai se mea'ai uamea fa'aitiitia mālūlū o lo'o fa'apipi'iina ai se vaega o le zinc e ala i se fa'aulu vevela e tu'uina atu ai mea fa'alelei atili i luga o le sila.
★ uʻamea malu uamea (GMS) e mafai ona faʻaaogaina e fai ma paluga ma faʻaululima o faasitepu, paipa ma isi.
★ O isi u'amea fa'avae zinc o lo'o ufiufi i luga o le sila ma fa'aaogaina e fai ma mea e fa'apipi'i ai le u'amea, e maua ai mea eseese. Latou te tuʻuina atu le faʻaleleia atili o le pala i tulaga faʻapitoa.
★ Electro-galvanised (EG) uamea ufiufi e aofia ai se mea malulu faaitiitia i luga o lea e ufiufi ai se vaega o le zinc e se faiga electrolytic.
★ u'amea fa'aitiiti mālūlū (CR) e aunoa ma se fa'a'ofuina o le zinc
★ u'amea alumini ga'o
★ O le tele o isi substrates e faʻapipiʻiina faʻaletino: zinc / uʻamea, uʻamea uʻamea, tinplate, apamemea, zinc ma kopa.
Fa'alavalava
O lo'o fa'aogaina le tele o mea fa'apipi'i fa'aola mo u'amea ua uma ona valiina, fa'atupuina ina ia tu'uina atu tulaga eseese o le tumau ma le fa'atinoga, po'o le fa'amalieina o mana'oga fa'alelei eseese. O fa'alavalava e masani ona fa'aogaina e fa'avae ile vali vai, e ui o ata (fa'aigoa o laminates) ma pa'u pa'u e fa'aogaina i ni vaega laiti. O vali vai ia (fa'ata'ita'iga, mea fa'auma, 'ofu fa'auma/tua, polyesters, plastisols, polyurethanes, polyvinylidene fluorides (PVDF), epoxies), pa'u pa'u ma ata laminate.
O vali vai e sili atu i le 90% o faʻalava na faʻaaogaina mo uʻamea vali. O ata tifaga e masani ona faʻaaogaina i mea e manaʻomia ai le maualuga o le matagofie. E mafai ona ausia suiga i le mafiafia o ata tifaga, lanu ma le fa'ai'uga ( lamolemole, fa'atulagaina pe lolomi. O pa'u pa'u e mafai ona fa'amatalaina o le "vali malo" lea e mafai ona liusuavai e fai ai se ata fa'aauau i luga o le mea'ai. O ituaiga faʻapipiʻi taʻitasi e iai ona lava faʻamanuiaga faʻapitoa, pe o le mafiafia, susulu, maaa, fetuutuunai, tumau i le tau leaga poʻo le tetee atu i osofaʻiga vailaʻau. O le filifiliga o le faiga e sili ona talafeagai e tatau ona faʻavae i luga o lona faʻaogaina ma faʻamoemoega faʻatinoga.
