O la matou fa'atonuga e tatau ona tu'uina atu i a matou tagata fa'aoga ma tagata fa'atau oloa ma fofo sili ona lelei ma taugofie mo le Top Grade Sodium Sulfide 25kg Specification, O oloa uma e gaosia i masini fa'aonaponei ma faiga fa'atonutonu fa'amaoni ina ia mautinoa le maualuga o le tulaga lelei. Talia tagata fa'atau fou ma matutua e fa'afeso'ota'i matou mo le galulue fa'atasi fa'apisinisi.
O la matou galuega e tatau ona faia o le auauna atu lea i tagata faʻaoga ma tagata faʻatau i oloa ma fofo faʻatekinolosi feaveaʻi sili ona lelei ma taugofie. Matou te talia le avanoa e fai pisinisi ai ma oe ma matou te faʻamoemoe e fiafia e faʻapipiʻi atu nisi faʻamatalaga o a matou oloa. E mafai ona faʻamaonia le lelei tele, tau taugofie, tuʻuina atu i le taimi atofaina ma le tautua faʻatuatuaina. Mo nisi fesili, aua le faʻatuai e faʻafesoʻotaʻi matou.













O le aʻoaʻoina o tagata faigaluega fou e tatau ona taulaʻi i le tali atu i faʻalavelave faʻafuaseʻi o le Sodium Sulfide. Faʻataʻitaʻi ni tulaga o le masaa o le reagent ma faʻataʻitaʻi vave le faʻamamāina i le vavae faʻapitoa e mitiia ai le vai. E tatau ona aofia i iloiloga le ofuina saʻo o ufimata kesi i totonu o le 20 sekone. Sodium Sulfide E tatau ona faʻatulagaina ni faʻataʻitaʻiga masani mo le tafe o le eletise, e aofia ai ma faʻatonuga mo tali atu i faʻalavelave faʻafuaseʻi mo le motusia faʻafuaseʻi o le eletise.
