The application discloses a welding rod for 1000MPa high-strength steel and a preparation method thereof. The welding rod comprises a coating and a welding core, and the coating is wrapped on the outside of the welding core. The coating powder comprises the following components in parts by weight: 30-35 parts of fluorite, 20-30 parts of dolomite, 5-8 parts of strontium carbonate, 2-5 parts of sodium titanium silicate, 5-10 parts of potassium oxalate, 5-10 parts of atomized ferrosilicon, 2-5 parts of titanium powder, 0.5-1.0 parts of lanthanum cerium fluoride, 1-5 parts of lithium carbonate, 1-2 parts of sodium carboxymethyl starch, 0.5-1.5 parts of copper powder and 8-15 parts of iron powder. The welding rod has excellent all-position welding process performance, the arc is stable during welding, fine droplet transition is presented, the molten slag has moderate fluidity, the welding spatter is small, and the weld formation is fine and beautiful.

This invention relates to the field of dichloromethane waste gas treatment technology, specifically disclosing a molten salt-assisted preparation method for ultra-microporous activated carbon used to remove dichloromethane. The method of this invention includes the following steps: urea, potassium oxalate, chloride salt and coconut shell carbonized material are mixed and ground in different proportions, and then activated at 800℃ for 60 min to obtain a series of ultra-microporous activated carbons. The preparation method provided by this invention can control the pore structure of activated carbon to obtain adsorption materials with excellent dichloromethane purification performance. The material synthesis is simple, the cost is low, and it has the conditions for large-scale production.
