2. Tulaga lelei o oloa
3. Fa'aoga
faatoaga: Phosphoric acid o se mea mataʻina taua mo le gaosiga o phosphate fertilizers (superphosphate, potassium dihydrogen phosphate, ma isi) ) mea mata.
Alamanuia: Phosphoric acid o se vailaʻau mataʻutia taua, ma o ana galuega autu o loʻo mulimuli mai:
1. Fa'amama le u'amea ma fai se ata phosphate e le mafai ona fa'aaogaina i luga o le u'amea e puipuia ai le uamea mai le pala.
2. Faʻafefiloi ma le nitric acid e avea o se vailaʻau faʻamalo e faʻaleleia ai le lamolemole o le uʻamea.
3. Phosphateesters, mea mata mo le gaosiga o vailaau ma vailaau faʻasaina.
4. Mea mata'utia mo le gaosiga o phosphorus-i totonu o le afi mumu
Mea'ai: Phosphoric acid o se tasi o mea'ai faaopoopo. E fa'aaogaina i mea'ai e fai ma sui oona ma mea fa'afefete. Coca-Cola o loʻo iai le phosphoric acid.O le Phosphate ose mea'ai fa'aopoopo taua ma e mafai ona fa'aaogaina e fai ma fa'aleleia mea'ai.
O le uamea luga "fosforification togafitiga". O le mea e taʻua o le phosphorus e faasino i le auala e gaosia ai mea faigaluega uʻamea e ala i se vaifofo acidic o loʻo i ai le masima dihydrogen -phosphate, ma se auala e faʻatupuina ai se faʻamaumau e le mafai ona faʻaogaina le phosphate membrane i luga o lona luga e faʻatupu ai se gaioiga faʻamaʻi. O le membrane e taʻua o le phosphorum film. O le faʻamoemoega autu o le ata o le phosphorum o le faʻateleina lea o le faʻapipiʻiina o le ata faʻapipiʻi ma faʻaleleia le faʻafefeteina o le paʻu. E tele auala e faʻafefe ai le phosphorus. E tusa ai ma le vevela i le taimi o le phosphorusization, e mafai ona vaevaeina i le maualuga o le vevela phosphorus (90-98 ° C), vevela vevela phosphorus (60-75 ° C), maualalo vevela phosphate (35-55 ° C) ma le N potu vevela phosphorus.
O le tekinolosi passivation o le ata phosphorum e masani ona faʻaaogaina i Amerika i Matu ma Europa. O le faʻaaogaina o tekinolosi faʻaogaina e faʻavae i luga o uiga o le phosphate film lava ia. E manifinifi le ata o le phosphorum. E masani lava, o le 1-4g / m2, lea e le sili atu i le 10g / M2, o lona avanoa avanoa pore e tele, ma o le ata lava ia e faʻatapulaʻaina le faʻafefeteina. O nisi e vave ona ele samasama a'o fa'agogo. A maeʻa le phosphorusization, e mafai ona faʻamalosia atili le faʻamaʻiina ma le tapunia o togafitiga e le uʻamea o loʻo faʻaalia i totonu o pores o le ata phosphorurative, poʻo le faʻaogaina o le passivation layer. Ole a'afiaga ole fa'ama'iina e fa'amautu ai le phosphate ile ea.
O le ata o le liua o le phosphate o loʻo faʻaaogaina i le uʻamea, alumini, zinc, cadmium, ma ona alo, lea e mafai ona faʻaaogaina e fai ma faʻamaʻi faʻamaʻi mulimuli poʻo le ogatotonu o isi faʻasalalauga. O lana matafaioi e iai vaega nei.
E ui lava o le Faʻaleleia o le ata phosphorurative e manifinifi, ona o se mea e le -metal non-conductive isolation layer, e mafai ona suia le conductor lelei o luga o le mea faigaluega uamea i se conductor leaga, taofia le fausia o micro-eletise i luga o le fogaeleele. le mea faigaluega u'amea Fa'aleaogaina o ata fa'apipi'i. Ole Siata 1 o lo'o lisiina ai a'afiaga ole phosphate film ile tete'e ole u'amea.
Faʻaleleia le faʻapipiʻiina o ata i le va o le matrix ma le faʻapipiʻi poʻo isi mea teuteu faʻaola o se fausaga faʻapipiʻi atoa e tuʻufaʻatasia se vavalalata vavalalata. E leai se tuaoi manino i le vaitaimi. O mea porous o le ata phosphorurative e faia ai le sui tapuni, faʻaofuofu, ma isi mea e ulu i totonu o nei pores, ma faʻapipiʻi vavalalata i le membrane phosphoridized, ina ia faʻaleleia atili ai le pipii.
Tuuina atu se ata mama phosphorus i luga e mafai ona tupu i luga o le uʻamea workpiece e aunoa ma le filogia o suauu ma le ele-leai vaega. O le mea lea, o mea faigaluega u'amea sa fai phosphorus e mafai ona maua ai le mama, toniga, ga'o-noa ma elea luga.
