The invention belongs to the technical field of paint spraying and particularly relates to a protection method for preventing splashing pollution during paint spraying. The protection method comprisesthe following steps that first, a spraying opening of a paint spraying machine is cleared to remove dirt and residual paint near the spraying opening; second, the surface of a to-be-sprayed metal plate is cleaned up to guarantee that no chipping and no water spot remain; and third, a device for preventing splashing pollution during paint spraying is fixed to the edge of a to-be-sprayed area of the metal plate surface. According to the protection method for preventing splashing pollution during paint spraying, the device for preventing splashing pollution during paint spraying in the third step prevents the paint from splashing out of the to-be-sprayed area; and according to the device for preventing splashing pollution during paint spraying, the periphery of the to-be-sprayed area is protected through a plastic film, the splashing paint is blocked by the plastic film in the paint spraying process, the plastic film can be torn off after paint spraying, using is convenient, and the paint splashing prevention effect is good.

The invention discloses a construction method of an underwater blocking net, and relates to the technical field of underwater salvage equipment. The construction method of the underwater blocking net comprises the following steps that S1, the two ends of the bottom of the blocking net are connected with anchor chains; S2, the blocking net and the two anchor chains are put into water through a workboat; and S3, bases are arranged at the two ends of a river bank. According to the construction method of the underwater blocking net, stormy waves drive water flow to impact an inclined plate, so that the inclined plate is stressed to deflect, meanwhile, the inclined plate drives an elastic plate to extrude each other during deflection, the elastic plate can drive the inclined plate to continuously vibrate, and an elastic film is pulled through a second pull rope while the inclined plate deflects or vibrates, so that a device can be prevented from being damaged due to excessive deflection of the inclined plate, it can also be guaranteed that the inclined plate deflects to pull the elastic film, the elastic film and the water waves are continuously slapped to make a sound, and the buoy finding and seeking effect is good during underwater rescue.

Water-continuous composition comprising 75 to 90 wt % liquid oil, comprising 0.05 to 5 wt. % of a porous powderous vegetable matter made from nuts, seeds, beans kernels, pits and cellulose having a volume weighted mean particle diameter (d_4,3) not exceeding 0.5 mm.

The invention discloses a welding spatter prevention agent. The welding spatter prevention agent comprises 25 parts of solvent naphtha, 5 parts of petroleum ether and 70 parts of oil-based materials per centum, wherein the base-based materials are lubricating oil, the above raw materials are subjected to high-temperature blending and stirring, and the agent is obtained. A preparing method of the welding spatter prevention agent comprises the five procedures of weighing, primary stirring, secondary stirring, filling and packaging. When the agent is used, a user directly sprays the agent to thesurface of a non-welding surface, due to the fact that the oil-based materials that is the lubricating oil are used as the main raw materials, the oil-based materials can effectively form an isolationfilm between welding slag and the object surface, adhesive power between the welding slag and the object surface can be reduced, and the welding slag is prevented from being bonded on the object surface. Convenience is brought to the welding work, labor intensity of a worker is reduced, work efficiency and product fineness can be improved, dust and noise pollution can be reduced, and on the basis, the agent has the good application prospect.

The invention provides a gas-liquid distribution disk for a hydrogenation reactor. The gas-liquid distribution disk comprises a disk plate, wherein the disk plate is provided with multiple distributors; the distributors are provided with cylindrical bubble caps; the centers of the tops of the bubble caps are provided with round holes, the bottoms of the side surfaces of the bubble caps are provided with tooth seams; the bubble caps are internally provided with central pipes coaxial with the bubble caps; bubble cap supports are welded at the tops of the central pipes, bubble cap auxiliary positioning plates are welded at the middles of the central pipes and the bottoms of the central pipes are covered by clamp plates; the tops of the clamp plates are provided with fixed pull rods, the side surfaces of the clamp plates are provided with bumps, and the bottoms of the clamp plates are provided with stream breakers; the bubble caps and the central pipes are connected by virtue of the clamp plates and the fixed pull rods and fixed to the disk plate. The gas-liquid distribution disk has the characteristics of reliable structure, reasonable design and uniform material distribution; by use of spiral tooth seams, the gas carrying capability can be improved, and a rotation effect can be generated by a medium; the structure of the distributor is simplified by virtue of the design of the fixed pull rods, and the central pipes and the bubble caps are fixed to the disk plate by only locking fixed nuts at the tops of the pull rods.
