Examples
Embodiment 1
[0021] Take 70% sodium hydroxide, 20% trisodium phosphate, 5% n-tetradecyl polyoxyethylene ether, 3% sodium oleate, and 2% triethanolamine by weight, and mix the above raw materials evenly to make an annealed plated Cleaning agent for tin pre-treatment steel plate 1.
[0022] Add cleaning agent 1 for pre-tinned steel plate after annealing directly to the water in the cleaning section before tinning, so that the weight percent concentration is 3%, and the annealed steel plate is cleaned at a cleaning temperature of 75°C, and the cleaning efficiency is 99%. Above, the residue on the steel plate surface is less than 6mg / m 2 .
Embodiment 2
[0024] Take 80% sodium hydroxide, 10% trisodium phosphate, 3% tetradecyl polyoxyethylene ether, 5% sodium oleate, and 2% triethanolamine by weight. Tin pre-treatment steel plate cleaning agent 2.
[0025] Add cleaning agent 2 for pre-tinned steel plate after annealing directly to the water in the cleaning section before tinning, so that the weight percentage concentration is 3%, and the annealed steel plate is cleaned at a cleaning temperature of 70°C, and the cleaning efficiency is 99.2% Above, the residue on the steel plate surface is less than 6mg / m 2 .
Embodiment 3
[0027] Take 72% sodium hydroxide, 12% trisodium phosphate, 6% n-tetradecyl polyoxyethylene ether, 7% sodium oleate, and 3% triethanolamine by weight, and mix the above raw materials evenly to make an annealed plated Cleaning agent for tin pre-treatment steel plate 3.
[0028] Add cleaning agent 3 for pre-tinned steel plate after annealing directly to the water in the cleaning section before tinning, so that the weight percent concentration is 4%, and the annealed steel plate is cleaned at a cleaning temperature of 80°C, and the cleaning efficiency is 99.3% Above, the residue on the steel plate surface is less than 6mg / m 2 .
