The invention belongs to the technical field of welding materials, in particular to a low-hydrogen easy-to-weld basic flux-cored wire for structural steel prepared from steel slag. It is made of low-carbon cold-rolled steel strip wrapped core powder, which includes steel slag 22%‑28%, Mo40V40Al20 powder 7.5%‑9.0%, FeMn60Si34C0.02 powder 5.6%‑8.2%, FeTi80‑A powder 4.1%‑ 5.0%, CaF plated with Ni on the surface 2 Powder 7.8%‑9.6%, Nano TiO 2 4.2%-6.0%, 200 mesh nitrocellulose powder 3.1%-3.8%, feldspar 2.1%-3.0%, and the balance is FHT100·25 reduced iron powder. The invention has stable arc, small spatter, good post-weld forming, easy slag removal, suitable for all-position welding, low residual hydrogen content in deposited metal, uniform chemical composition and high mechanical properties, and is an innovation in the field of basic flux-cored welding wire. .

The invention discloses a POE adhesive film with high electrical strength and electrical tracking resistance. The POE adhesive film comprises the following raw materials by weight: 70 to 90 parts of ethylene-octene copolymer modified particles and 10 to 30 parts of a functional masterbatch, wherein the functional masterbatch comprises the following raw materials by weight: 70 to 90 parts of an ethylene-vinyl acetate copolymer, 10 to 30 parts of an ethylene-methyl methacrylate copolymer, 0.1 to 5.0 parts of a photoinitiator and 0.5 to 3.0 parts of a stabilizer; and the stabilizer is a benzil stabilizer. The invention also discloses a preparation method for the above-mentioned POE adhesive film. On the basis that high transmittance and adhesion properties of the adhesive film are maintained,the POE adhesive film provided by the invention has high electrical strength and electrical tracking index resistance, is applied to packaging of a photovoltaic assembly, can effectively improve theelectrical strength and electrical tracking index resistance of the photovoltaic assembly, avoids large drop or failure of the power of the photovoltaic assembly in the process of photoelectric conversion, thereby greatly reducing hot spot effect and the phenomenon of electric breakdown damage or electrical tracking damage.
