This invention discloses a strippable coating for laser shock processing, which is composed of carbon powders 5-15 wt.%, bonding agent 50-70 wt.%, self-drying thinner 15-35 wt.% and additive 2-5 wt.%. The thickness of the coating layer is generally 60-150 mums. The strippable coating is manufactured by: (1) placing carbon powders in a reactor, and adding bonding agent, self-drying thinner and additive; and (2) stirring uniformly, and adjusting the pH value to 7.5 with 25% ammonia solution. The strippable coating can intimately adhere to the surface of metals, and cannot be stripped during continuous laser shock process, thus having a good shock effect.

The invention discloses a remover for removing biological slime in recirculated cooling water. The remover contains a polysorbate nonionic surfactant, a biosurfactant and an osmotic agent. The biosurfactant is a glycolipid-type biosurfactant. The invention also provides a method for removing biological slime in a recirculated cooling water system by the remover. The method comprises putting the remover into the recirculated cooling water. The remover effectively removes biological slime deposited on the equipment and pipes of the recirculated cooling water system, effectively improves effects of removing biological slime of the recirculated cooling water system, reduces a synthetic surfactant use amount, and reduces draining environment pollution caused by use of the synthetic surfactant.

The invention discloses a circulating cooling water biological slime stripping agent. Specifically, the biological slime stripping agent contains an alkylaryl sulfonate anionic surfactant, a biological surfactant and a penetrating agent. The invention also provides a method for stripping slime in a circulating cooling water system. The method includes putting the circulating cooling water biological slime stripping agent into circulating cooling water. The biological slime stripping agent provided by the invention can effectively strip the biological slime deposited on the equipment and pipeline inner walls of a circulating cooling water system. And by adopting the biodegradable and environmental friendly biological surfactant to replace parts of chemical synthesis surfactants, the dosage of chemical synthesis surfactants can be reduced, and at the same time, a good biological slime stripping effect can be achieved, and secondary pollution to the environment can be reduced.

The application discloses a method for stripping a photoresist on an Array plate, which is used for stripping and repairing the photoresist on the Array plate. The method comprises the steps of conducting dry-method stripping on the photoresist on the surface of the Array plate, and removing the over-baking part of the photoresist; coating photoresist stripper on the photoresist with the removed over-baked part, and carrying out a reaction on the photoresist stripper and the photoresist with the removed over-baked part, and stripping the photoresist with the removed over-baked part from the Array plate. The method for stripping the photoresist on the Array plate provided by the application is used for stripping and repairing the photoresist on the Array plate, the photoresist is subjected to the dry-method stripping, an extremely thin layer of over-baked photoresist in the post-baking process can be removed, then the residual photoresist is stripped by utilizing the photoresist stripping liquid, and then the photoresist on the Array plate can be stripped thoroughly.

The invention provides a preparation method of a tungsten disulfide nano sheet. The preparation method comprises the following steps: (1) mixing tungsten disulfide with a strong acid, carrying out full infiltration, and adding a ferrate or a metal peroxide for carrying out a reaction; (2) slowly and dropwise adding the reactant obtained after the reaction into deionized water for dilution; (3) carrying out ultrasonic treatment on the diluted liquid in an ultrasonic dispersion device; (4) carrying out standing on the dispersed liquid, and removing tungsten disulfide which is not stripped or hasa low stripping degree in the obtained precipitate; (5) carrying out suction filtration treatment on the supernatant liquid obtained after standing, washing the obtained material with hydrochloric acid, and then carrying out washing to neutrality by using deionized water; and (6) finally drying the obtained product to obtain the tungsten disulfide nano sheet. According to the method provided by the invention, the tungsten disulfide nano sheet is prepared by stripping through the reaction of the strong acid with the ferrate or the metal peroxide and through the ultrasonic action; the method issafe and stable, is free of pollution, and has easily available raw materials; the operation is easy; the equipment is simple; the yield is high; and the product quality is good.
