The invention provides a manufacturing method of a flexible display screen, a flexible glass substrate and a flexible display screen. The manufacturing method comprises the following steps: forming a TFT layer at one side of a flexible glass substrate; forming a high-molecular enhancement layer at the other side of the flexible glass substrate; solidifying the high-molecular enhancement layer; forming a display layer on the TFT layer; and forming a packaging layer on the flexible glass substrate at one side of the TF layer. The high-molecular enhancement layer is arranged at one side of the flexible glass substrate. The flexible display screen consists of a flexible glass substrate, a TFT layer, a high-molecular enhancement layer, a display layer, and a packaging layer. According to the invention, a defect of frangibility of the flexible glass substrate is overcome and the compressive strength of the flexible glass substrate is enhanced, thereby improving the product quality.

The invention discloses a water-lubricated composite material thrust bearing of a nuclear main pump, which comprises a stainless steel tile base and an engineering plastic layer. The stainless steel tile base has a concave-convex surface connected to the engineering plastic layer, and the concave-convex surface and the engineering plastic layer are composited by thermoplastic molding. For forming, the ratio between the area of ​​the concave-convex surface and the area of ​​the orthographic projection of the concave-convex surface on the stainless steel tile base is 1.2-2. The concavo-convex surface of the present invention and the engineering plastic layer are combined by the concavity and convexity of the concavo-convex surface, and the unique cohesiveness of the rough surface and the engineering plastic layer after melting to form a composite material thrust bearing with reliable physical connection as one, which can play Metals and non-metals have their own advantages, which can greatly reduce the thickness of the engineering plastic layer and improve the load-carrying capacity. Under the influence of pressure and temperature during operation, the bearing size still has good stability, which is more conducive to establishing a stable and safe lubrication. The water film is a new type of water-lubricated composite material thrust bearing that is anti-nuclear radiation, safe and reliable.

The invention provides a composite slag remover and a manufacturing process thereof, and belongs to the field of pulp slag removal equipment. The composite slag remover comprises an inner container (1) made of ceramic. The composite slag remover is characterized in that a layer of high molecular elastic material (2) coats the outer side of the inner container (1), and the inner container (1) and the high molecular elastic material (2) are composited into an integrated structure. The manufacturing process of the composite slag remover sequentially includes the steps that a green body, made of aluminum oxide, of the inner container (1) is prepared in an isostatic pressing mode under the pressure of 120-300Mpa, a numerically controlled lathe is utilized to turn the inner side and the outer side of the green body of the inner container (1), the green body is fired into the inner container (1), the molten high molecular elastic material (2) coats the outer side of the inner container (1) under the pressure of 20-30Mpa, and vulcanization is conducted. The composite slag remover has the advantages of being high in strength, light in weight, accurate in installing geometric dimension, convenient to install, low in using cost and friction coefficients of the ceramic inner container, and capable of improving the paper pulp purifying rate and achieving energy saving and environment friendliness.
