The invention relates to the field of sealing and particularly relates to a rubber barrel with relatively hard upper and lower end parts, which is used in an oil exploitation process and can bear high temperature and high pressure, a packer and a bridge plug. According to one aspect of the invention, the rubber barrel is provided; and the hardness of the upper end part of the rubber barrel is greater than that of the middle part of the rubber barrel, so that the deformation of the middle part in the radial direction is greater than that of the upper end part in the radial direction when the upper end part bears first axial pressure. The hardness of the upper end part of the rubber barrel is greater than that of the middle part of the rubber barrel, so that the upper end part is almost used for transmitting the first axial pressure to the middle part and the lower end part, but not utilizes the first axial pressure to self radial deformation when the upper end part bears the first axial pressure. Therefore, the middle part and the lower end part have the radial deformation when the relatively small first axial pressure is used, and the sealing of the whole rubber barrel is realized.

The invention relates to a preparation method of structure-enhanced silver/copper antibacterial zeolite and a product prepared from the structure-enhanced silver/copper antibacterial zeolite. According to the invention, the silicon-to-aluminum ratio of the zeolite is changed and a proper amount of modifiers (such as refractory mortar, zirconium phosphate or fly ash) are added so as to enhance the mechanical strength and stability of the zeolite and improve the defect that the traditional zeolite product is nondurable; and a gelatinizing agent of a sodium hydroxide or potassium hydroxide alkaline aqueous solution is added, and a hydrothermal gelatinizing process, molding (such as carrying out oil pressing to form a hollow cylinder shape), drying and calcining are carried out so as to prepare the durable and high-practicability zeolite product. In the antibacterial zeolite provided by the invention, silver ions with the best antibacterial property and copper ions with good antibacterial property and low cost are used as antibacterial metal ions; and compared with the conventional method in which single antibacterial metal is used, the preparation method disclosed by the invention can maintain the excellent antibacterial capacity of the silver ions, and by mixing the copper ions, the preparation cost is reduced, the acceptability of the antibacterial zeolite product is increased, so that the antibacterial zeolite product can be more widely applied to purification of indoor air.

By utilizing decabromodiphenyl ether as the flame retardant, the composite cored EPS foam plastic panel has good heat resistance, is healthy to a human body, has no risk and is environmentally friendly; hydrogen-containing silicone oil is added to be matchedwith the double-layer epoxy resin board and methyl hexahydrophthalic anhydride during the curing and stirring, so that the structural strength of the machined and formed EPS foam plastic panel is improved, and the EPS foam plastic panel dost not attract dust in a working environment with a high dust content, and the aesthetic degree of the EPS foam plastic panel is increased.

The invention relates to the field of sealing, in particularly to a rubber sleeve which can bear high temperature and high pressure and comprises a metal wire sealing ring, a packer and a bridge plug used in the oil exploitation industry. The rubber sleeve comprises the metal wire sealing ring and a fiber wire sealing ring, wherein the metal wire sealing ring and the fiber wire sealing ring abut against each other and are arranged on the lower portion. The metal wire sealing ring comprises a plurality of mutually intersecting metal wires and glue bonding the metal wires together. The fiber wire sealing ring comprises a plurality of fiber wires which mutually intersect and resist high temperature and high pressure and glue bonding the fiber wires together. When the metal wire sealing ring is arranged below the fiber wire sealing ring, axial pressure transmitted to the fiber wire sealing ring can be reduced due to the friction between the metal wire sealing ring and a central pipe and/or a sleeve pipe, and at the time axial pressure on the fiber wire sealing ring can be effectively reduced. The reason for generation of shoulder protrusion is too large axial pressure, so that generation of shoulder protrusion can be reduced or prevented through the design.
