The present invention relates to a siloxane hard resin including alicyclic epoxy siloxane alone or a reactive monomer, which is prepared by condensation reaction of alkoxysilanes, and has a weight average molecular weight in the range of 1000 to 4000 and a molecular weight distribution of PDI 1.05 to 1.4. A siloxane hard cured article produced by photo- or thermal polymerization has high hardness by compact crosslinking of siloxane molecules having different molecular weights.

The technical problem of this invention is to eliminate the need to use deformable panel walls and to find the body of a shape that no false deformation, such as dented deformation, takes place in a portion of the body due to the hot filling of the contents or the reduced pressure created by the treatment of retort-packed foods. The object of this invention is to obtain a bottle that can inhibit the deformation caused by reduced pressure, has a high buckling strength, and is good in outer appearance. As the solution, there is provided a biaxially drawn, blow-molded bottle made of a synthetic resin, in which the surface rigidity of the wall of body is set in such a manner that a part of the body wall cannot become dented inward under a reduced inner pressure of at least 350 mmHg (46.7 kPa).

A method of forming films over an insulating material is provided whereby an underlayer film having electric conductivity is formed on the surface of the insulating material constituting a base member, and a hard carbon film is formed over the underlayer film so that the surface electrical resistance value of the hard carbon film can be controlled so as not to cause the surface thereof to be charged with static electricity by varying an electrical resistance value of the underlayer film. In the case where the underlayer film is formed of a metal film composed of titanium, chromium, tungsten, or the like, the resistance value thereof can be changed by varying the thickness of the metal film. In the case where the underlayer film is formed of a semiconductor film composed of silicon, germanium, or the like, the resistance value thereof can be changed by varying the thickness of the semiconductor film, or the concentration of an impurity added thereto.

The invention discloses a low-temperature assisted ultrasonic surface rolling intensifying device and a processing method. The device consists of a surface rolling member, a loading member and a heating member, wherein a clamping handle is arranged on the surface rolling member; the loading member is arranged at the tail end of the surface rolling member; a spring, a pressure sensor, a baffle, a transducer and an amplitude-change pole are sequentially arranged on the end face of the loading member; the amplitude-change pole is provided with a rolling head of which the front end is provided with a roller through a guide sleeve; the outer side of the surface rolling member is connected with an ultrasonic generator; and the heating member is provided with a temperature controller and heating wires connected and controlled by the temperature controller According to the processing method disclosed by the invention, an ultrasonic rolling technology and low-temperature heating treatment are combined; on the basis of softening materials by using low temperature heating, an ultrasonic frequency electrical signal is converted into ultrasonic mechanical vibration by using the transducer; and after the ultrasonic mechanical vibration is amplified by the amplitude-change pole, vibration with a certain amplitude is outputted and transmitted to the rolling head, and high-speed vibration between the rolling head and workpieces in the rolling process is realized, thereby better refining material grains on the surface layers of the workpieces, and generating greater residual compressive stress and high surface hardness.

The gradient composite coating layer for continuous casting crystallizer copper plate contains Co in 50-79.9 vol%, Ni in 20-49.9 vol% and Al2O3 grains of size below 0.5 micron in 0.1-10 vol%. The coating is in gradient structure with outwards gradually increased Co and Al2O3 content and decreased Ni content. During production of the composite coating layer, inside amino sulfonate system with Al2O3 grains in 10-80 g / L and size below 0.5 micron added, gradient Co-Ni-Al2O3 coating is deposited onto copper or copper alloy via specific Al2O3 grain activating pre-treatment and electric deposition process. In the activating pre-treatment, FC-4 cation surfactant is used as ion dispersant. The composite Co-Ni-Al2O3 coating may be used in various high temperature wear resisting fields widely.

The invention belongs to the technical field of high polymer materials, and in particular relates to a polypropylene composite material for an automobile hard plastic instrument panel and a preparation method for the polypropylene composite material. The polypropylene composite material is prepared from the following raw materials in percentage by weight: 33 to 76 percent of polypropylene, 0 to 2 percent of heat stabilizer, 0 to 2 percent of processing aid, 0 to 2 percent of nucleating agent special for polypropylene, 10 to 20 percent of plasticizer, 2 to 6 percent of compatibilizer, 10 to 25 percent of superfine talc powder and 2 to 10 percent of chopped flat fiberglass. When the polypropylene composite material for the automobile hard plastic instrument panel is prepared, the chopped flat fiberglass is added, so that the surface hardness of the polypropylene composite material is increased, good scratch resistant effects are achieved without adding any scratch resistant agent, and a matte effect is also achieved; the polypropylene composite material also has the characteristics of high flowability, high rigidity, high heat resistance, high dimensional stability, high impact resistance, low glossiness and scratch resistance, and requirements on a material for the automobile hard plastic instrument panel are completely met.

The invention provides a cover plate of a bendable display panel. The cover plate comprises a glass substrate, the surface of the glass substrate is formed with a recessed area, and the recessed areathins the glass substrate to a bendable thickness; the recessed area is filled with a flexible material to form a bendable area of the cover plate in cooperation with a glass layer of the recessed area; the cover plate has the advantages of using glass in a non-bending area and using a stricture of ultra-thin glass filled with a flexible material in the bendable area to achieve the technical effects of reducing the cost of the bendable cover plate, increasing the surface hardness and enhancing the user's hand feeling.
