The steel( zinc department) phosphoric acid salt surface processing craft
Take off to want
At a merit and shortcoming that experimented to check the cultural heritage understanding 磷 chemical engineering skill various type before,but the zinc department function is good is a main direction study currently,so put forward the zinc department phosphoric acid salt processing conduct and actions to study the direction originally.The certain 磷 of experiment turns various condition of handle the craft,the temperature is a 30-500 Cs,the PH is worth to 2.8 or so,the accelerant is the second sodium nitrate 1.0 gs/ L,the additive turns the 1.0-1.5 gs/ L of 钠 for the fluorine.Pass again just hand over to experiment the assurance the low temperature 磷 turns the formulation:The butter of zinc is a 8.00 gs/ L,the phosphoric acid is a 0.07 mols/ L,nitric acid is 0.06 mols/ L,the nitric acid 镍 is 1.00 gs/ L.
Key word:The 磷 turn,the cupric sulfate intravenous drop,bear the eclipse,just hand over to experiment
