The utility model discloses an anti-corrosion coating polishing device, and particularly relates to the technical field of anti-corrosion coating polishing, a box body and two mounting joints are arranged, a rack, a fixing frame, a plate fixing mechanism and a polishing mechanism are arranged, a polishing space is formed on the rack, the fixing frame is mounted at the top of the rack, and the plate fixing mechanism is mounted on the rack. The fixing frame extends upwards to the position above the grinding space, the plate fixing mechanism is movably installed in the grinding space, the grinding mechanism is installed on the fixing frame and located above the grinding space, and the grinding mechanism can be close to the grinding space so as to grind the to-be-ground plate fixed by the plate fixing mechanism. Therefore, the plate to be polished can be fixed without manual operation during use, the function of automatically fixing the plate to be polished is achieved, large-scale and high-efficiency production is ensured, and industrial operation is achieved.

The invention belongs to the technical field of biological medicines, and discloses an anti-tumor polypeptide composition as well as a preparation method and application thereof. The composition is prepared from the following components in parts by weight: 10 to 30 parts of mucopolysaccharide combined hybrid peptide (polypeptide A) extracted from the body wall of the sea cucumber, 5 to 15 parts of angiogenesis inhibiting peptide RGD-4C, 5 to 10 parts of tumor penetrating peptide iRGD, 3 to 8 parts of thymosin alpha 1, 2 to 6 parts of ganoderma lucidum polysaccharide and 1 to 4 parts of vitamin C palmitate. Wherein the polypeptide A is prepared by a process comprising specific ultrasonication, ultrafiltration, ion exchange chromatography and reversed-phase liquid chromatography purification. The invention also provides a preparation method of the composition, which comprises the steps of weighing, sterile mixing, grinding and sub-packaging, and can be further prepared into dosage forms such as freeze-dried powder injection and the like. The composition can be used for preparing medicines for treating solid tumors such as lung cancer, breast cancer, colorectal cancer, liver cancer and the like through synergism of multiple components and multiple target points, and can be combined with chemotherapeutic medicines such as paclitaxel and the like.

The present invention relates to a pouch film laminate in which a base material layer, a gas barrier layer, and a sealant layer are laminated in this order, in which the sealant layer comprises a first sealant layer comprising a polypropylene random copolymer and a second sealant layer comprising a crosslinked polypropylene, and the degree of crosslinking of the second sealant layer is in the range of 52% to 80%.

This utility model discloses a fume extraction device for rib welding, belonging to the field of rib welding technology. It includes a fume extraction pipe, with a fume extraction hood fixed to one end. The fume extraction hood has a ventilation groove inside, and a connecting port is provided at one end of the inside of the fume extraction pipe. Support frames are symmetrically fixed to the bottom of the fume extraction pipe, and a reinforcing frame is fixed to the upper end of the support frames. A positioning plate is fixed to one side of the bottom end of the support frames. This utility model, by installing a fixed fume extraction device at the rib welding point, promptly removes harmful gases generated during welding, preventing personnel exposed to this environment for extended periods from inhaling large amounts of harmful substances. This improves the working environment, avoids short-term discomfort such as eye irritation, dizziness, and nausea caused by fume dispersion, enhances employee comfort, and prevents the rapid removal of fume from obstructing the welding line, reducing rework or defects, improving welding precision, and ensuring welding quality and safe production.
