Embodiment 1
[0032] Preparation of liquid metal treatment agent
[0033] In 1000 parts of water, add the following components:
[0034] Sodium hydroxide 345 parts
[0035] Hydrazine hydrate 85 parts
[0036] Sodium chloride (or potassium chloride) 67 parts.
[0037] The preparation method of liquid metal composite material, concrete steps are as follows:
[0038] 1) Provide shaped liquid metal substrates, especially aluminum-based liquid metals.
[0039] 2) Carry out surface decontamination treatment to liquid metal substrate, to remove the stain on its surface;
[0040] The surface decontamination formula is: KOH65g / L, K2CO345g / L, sodium dodecylbenzenesulfonate 1.5g / L, decontamination temperature 60°C, decontamination time depends on the specific decontamination effect.
