Embodiment approach

[0023]As a specific embodiment of the present invention, one end of the vertical plate 33 located in the second chamber 22 is fixedly connected with a moving plate 4, and the two sides below the moving plate 4 are fixedly connected with an airbag 41, and the airbag 41 is far away from the moving plate 4. One end of the airbag 41 runs through the horizontal plate 11, and air holes 42 are provided on both sides of the airbag 41. When the moving plate 4 moves up with the vertical plate 33, the airbag 41 stretches to bring the gas in the first chamber 21 into the second chamber 22; When the plate 33 moves up, it drives the moving plate 4 to move up. After the moving plate 4 moves up, the air bag 41 is stretched. After the air bag 41 is stretched, the gas in the first chamber 21 enters the second chamber through the air hole 42 on the air bag 41 In the chamber 22, because the eight-hydrate barium hydroxide crystal and the ammonium chloride crystal in the second chamber 22 react to a...

Abstract

The invention belongs to the technical field of polypropylene plastics, and particularly relates to a polypropylene sheet. The polypropylene sheet comprises a sheet body; a rectangular cavity is formed in the sheet body, and the interior of the rectangular cavity is divided into a first cavity and a second cavity through a transverse plate made of polypropylene. A liquid storage chamber is formed in the top of the sheet body, a group of partition plates are attached to the interior of the liquid storage chamber, the adjacent partition plates are connected through compression springs, and mercury is filled between the ends, away from the compression springs, of the partition plates and the liquid storage chamber in a sealed mode. The polypropylene sheet is simple in modeling, and the pull rope can be separated from the piston plate on the basis that mercury is heated to expand, so that the barium hydroxide octahydrate crystals and the ammonium chloride crystals are subjected to mixed reaction to absorb heat, and the purpose of cooling the polypropylene sheet is achieved. When the temperature is high, the sheet body is protected, and therefore the polypropylene sheet holds the advantages of being high in impact resistance, tough in mechanical property and resistant to corrosion of various organic solvents and acid and alkali.

Description

technical field [0001] The invention belongs to the technical field of polypropylene plastics, in particular to a polypropylene sheet. Background technique [0002] Polypropylene is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in the industry and is one of the common polymer materials. Australian coins are also made from polypropylene. [0003] Although polypropylene has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion, its shortcomings are also very prominent, mainly because of its low melting point, which is about 135 ° C, so it is not resistant to High temperature, and in the high temperature state, its rigidity is insufficient, and it is easy to deform, so that its original advantages are lost. This is a problem that polypropylene needs to solve in the ...
