A method for manufacturing an enamel-coated bullet is described. The method starts with casting a bullet from a metal material and quenching the cast bullet. After the bullet cools, applying a lubricant to the bullet and sizing the bullet to the appropriate caliber and rinsing the bullets in a solvent. Thereafter, applying an enamel coating to the bullets. The coating uses about 1 part by volume lacquer thinner, about 1.5 parts by volume hardener, and about 2.5 parts by volume epoxy paint. The process continues by contacting the bullets with a moving fluid for a sufficient time that they become dry and heating the bullets in an oven at a temperature of between 150 and 250° F. for a time between 20 and 45 minutes. Finally, the process involves applying a lubricant to the coated bullet and resizing the bullet to the appropriate caliber.

The invention relates to a preparation method of a molybdenum disulfide-based lubricating coating, which relates to the technical field of chemical composition application. It is to wash, dry and phosphate the workpiece to be coated; then use molybdenum disulfide as a lubricant, epoxy resin as a binder, banana water as a diluent, and ethylenediamine as a curing agent. The prepared molybdenum disulfide-based lubricating coating is coated on the surface of the workpiece; under normal temperature conditions, it is naturally dried for 20-30 minutes to form a molybdenum disulfide-based lubricating coating. Compared with the prior art, it has the advantages of simple and convenient production process, low production cost and good product quality.

The present invention discloses a restoration solution for cine film bubble and a restoration method. The restoration solution comprises 100 parts by volume of n-butanol, 60 to 120 parts by volume of lacquer thinner having 5% by mass of ethyl cellulose, 8 to 20 parts by volume of diphenyl isooctyl phosphite, 2 to 10 parts by volume of bis (1,2,2,6,6-pentamethyl-4-piperidyl) sebacate, and 2 to 15 parts by volume of petroleum ether. The present invention integrates micro-restoration, bubble puncture and optical filling, and effectively restores a bubble having a diameter of 0.1 mm to 1 mm generated between a film base layer and an emulsion layer of a cine film. The present invention has advantages of simple method of operation, low cost and good controllability. And the used restoration solution has good thermal stability, oxidation resistance, and permeability, and can eliminate the phenomenon of light scattering within the bubble, so that patterns and writing of the original image data are explicitly presented, and a better restoration effect is achieved without damages to films. Therefore, the restoration solution has good application values and market prospects.

The invention relates to the field of detergents, particularly a banana oil paint detergent which is composed of the following components in parts by weight: banana oil, sodium dodecyl benzene sulfonate, sodium hydroxide, sodium hydroxide, ethoxylated sodium alkyl sulfate, dichloromethane and deionized water. By using the banana oil as the solvent, the anionic surfactants sodium dodecyl benzene sulfonate and ethoxylated sodium alkyl sulfate are combined, thereby obviously displaying the activity of the anionic surfactant and enhancing the depainting effect and depainting efficiency.

The invention discloses a screw propeller rust removing and painting device for a civilian ship. The device comprises a device body in which a rust removing chamber is formed, wherein storing spaces are symmetrically formed at the upper part and the lower part of the left side of the rust removing chamber; a switch chamber is arranged at the right sides of the storing spaces; a rust removing agent is fed to an empty chamber through a second feeding port; lacquer thinner is fed through a first feeding port in the upper side; an anti-rust paint is fed through a first feeding port in the lower side; and then a screw propeller shaft is inserted into a clamping block. With the adoption of the device, a small screw propeller can be fully automatically subjected to rust removing and painting treatment; compared with a manual rust removing method, the device has the advantage that the efficiency is greatly improved; the rust removing and painting are carried out in a sealing condition, so that the corrosive damage of the rust removing agent to people can be prevented; and meanwhile, the damage of paint to respiratory tract of people can be prevented.

The invention provides a cleaning solution capable of preventing a low-hardness PVC injection molded part from paint peeling-off and a cleaning treatment process. The cleaning solution is prepared by mixing a lacquer thinner and alcohol in which the content of ethanol is larger than or equal to 95% at the volume ratio of 1: 3. A face needing to the painted of the low-hardness PVC injection molded part is immersed into the cleaning solution to be wholly soaked for 1-3 seconds, so that oil fouling on the surface of the low-hardness PVC injection molded part is dissolved; then the low-hardness PVC injection molded part is taken out from the cleaning solution and immediately submerged into fresh water to be wholly soaked for at least 4 min, so that the dissolved oil fouling is separated from the surface of the low-hardness PVC injection molded part to emerge from water; the low-hardness PVC injection molded part is taken out and aired to be used for surface painting till the face needing to the painted of the low-hardness PVC injection molded part is clean in fresh water. After the low-hardness PVC injection molded part is subjected to cleaning treatment before painting, a paint sprayed on the surface of the low-hardness PVC injection molded part cannot peel off, so that the product quality of batch production is guaranteed, the labor intensity of workers is greatly reduced, and the long-lasting difficult-to-solve problem that the paint on the surface of the injection molded part peels off in the injection product manufacturing industry is effectively solved.
